1. NATURE OF OPERATIONS

Western Copper and Gold Corporation (together with its subsidiaries, "Western" or the "Company") is directly engaged in exploration, permitting and development of the Casino mineral property located in Yukon, Canada (the "Casino Project").

The Company is incorporated in British Columbia, Canada. Its head office is located at 907-1030 West Georgia Street, Vancouver, British Columbia. 

While Western has been successful in raising sufficient capital to fund its operations, if the Company successfully progresses through permitting to the development and construction stage for the Casino Project, the Company will need to raise additional funds to complete the development and construction of the Casino Project. There can be no assurance that it will be able to raise such project financing in the future. 

2. BASIS OF PRESENTATION

a. Statement of compliance

These condensed interim consolidated financial statements have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board ("IFRS Accounting Standards") as applicable to the preparation of interim financial statements under IAS 34, Interim Financial Reporting. The condensed interim consolidated financial statements should be read in conjunction with the Company's annual consolidated financial statements for the year ended December 31, 2024, which have been prepared in accordance with IFRS Accounting Standards.

These financial statements were approved for issue by the Company's board of directors on November 6, 2025.

b. IFRS Pronouncements

Amendments to IFRS 9 and IFRS 7 - Amendments to the Classification and Measurement of Financial Instruments 

In May 2024, the IASB issued Amendments to the Classification and Measurement of Financial Instruments (Amendments to IFRS 9 and IFRS 7). These amendments updated classification and measurement requirements in IFRS 9 Financial Instruments and related disclosure requirements in IFRS 7 Financial Instruments: Disclosures. The IASB clarified the recognition and derecognition date of certain financial assets and liabilities, and amended the requirements related to settling financial liabilities using an electronic payment system. It also clarified how to assess the contractual cash flow characteristics of financial assets in determining whether they meet the solely payments of principal and interest criterion, including financial assets that have environmental, social and corporate governance (ESG)-linked features and other similar contingent features. The IASB added disclosure requirements for financial instruments with contingent features that do not relate directly to basic lending risks and costs and amended disclosures relating to equity instruments designated at fair value through other comprehensive income. 

The amendments are effective for annual periods beginning on or after January 1, 2026, with early application permitted. Management is currently assessing the effect of these amendments on our financial statements.

IFRS 18 - Presentation and Disclosure in Financial Statements

In April 2024, the IASB issued IFRS 18, Presentation and Disclosure of Financial Statements (IFRS 18), which replaces IAS 1, Presentation of Financial Statements. IFRS 18 introduces a specified structure for the income statement by requiring income and expenses to be presented into the three defined categories of operating, investing and financing, and by specifying certain defined totals and subtotals. Where company-specific measures related to the income statement are provided, IFRS 18 requires companies to disclose explanations around these measures, which are referred to as management-defined performance measures. IFRS 18 also provides additional guidance on principles of aggregation and disaggregation which apply to the primary financial statements and the notes. IFRS 18 will not affect the recognition and measurement of items in the financial statements, nor will it affect which items are classified in other comprehensive income and how these items are classified. The standard is effective for reporting periods beginning on or after January 1, 2027, including for interim financial statements. Retrospective application is required, and early application is permitted. Management is currently assessing the effect of this new standard on our financial statements.

c. Accounting estimates and judgments

The preparation of financial statements in conformity with IFRS Accounting Standards requires management to exercise judgement in the process of applying its accounting policies and to make estimates that affect the reported amounts of assets and liabilities and disclosures of contingent assets and contingent liabilities at the date of the financial statements and the reported amounts of income and expenses during the period. Actual results could differ from those estimates. Differences may be material.

The Company is required to make significant judgements in assessing whether there are any indicators of impairment relating to its exploration and evaluation asset. If any such indicator exists, then an impairment test is performed by management. Indicators of impairment may include (i) the period for which the entity has the right to explore in the specific area has expired during the year or will expire; (ii) substantive expenditures on further exploration for the evaluation of mineral resources in the specific area is neither budgeted nor planned; (iii) sufficient data exists to support that extracting the resources will not be technically feasible or commercially viable; and (iv) development or sale of a specific area is unlikely to recover existing exploration and evaluation asset costs. If any of these indicators are present, management would need to assess whether the exploration and evaluation asset should be impaired. There are no indicators of impairment as of September 30, 2025.

Changes in any of the assumptions or estimates used in determining the recoverable amount could impact the impairment analysis. Management did not identify any impairment indicators during the nine months ending September 30, 2025. 

Judgment is required in assessing whether a mineral property is in the exploration and evaluation phase and should be classified as an exploration and evaluation asset or if the exploration and evaluation phase has been completed and the mineral property should be reclassified as property and equipment. We determined that although a feasibility study for the Casino Project has been completed, the Company has not yet received the necessary licenses and permits required to consider the exploration and evaluation stage to have been completed.

9. EQUITY INCENTIVE PLANS

The Company has three equity incentive plans consisting of a stock option plan (the "Option Plan"), a restricted share unit plan (the "RSU Plan") and a deferred share unit plan (the "DSU Plan") (collectively the "Equity Incentive Plans"). Pursuant to the Company's annual general meeting held on June 17, 2021, it was approved that the maximum aggregate number of common shares issuable under the Equity Incentive Plans cannot exceed 10% of number of common shares issued and outstanding.

a. Stock Options and Share-based payments

Stock Options

Under the Option Plan, the exercise price of the stock options must be greater than, or equal to, the market value of the Company's common shares on the last trading day immediately preceding the date of grant. Stock options vest over a two year period from the date of grant unless otherwise determined by the directors. The maximum stock option term is 10 years. At September 30, 2025, the Company could grant an additional 3,740,311 stock options under the terms of the stock option plan. A summary of the Company's stock options outstanding and the changes for the periods then ended, is presented below:

During the three and nine months ended September 30, 2025, the Company recognized an expense in respect of stock options of $198,040 and $747,872, respectively, in the statement of loss and comprehensive loss (three and nine months ended September 30, 2024 - $293,488 and $1,024,780, respectively). During the three and nine months ended September 30, 2025, $22,296 and $95,602, respectively, was capitalized (three and nine months ended September 30, 2024, $17,017 and $46,896, respectively) in the exploration and evaluation assets in relation to stock options.

On June 12, 2025, 200,000 stock options were exercised by a former director of the Company. The proceeds from this exercise were settled against the cash payable pursuant to a concurrent DSU settlement (Note 9c).

Stock options outstanding are as follows:

The average share price for options exercised during the nine months ended September 30, 2025, was $1.54 (nine months ended September 30, 2024 - $1.26). Of the total stock options outstanding, 4,031,994 were vested and exercisable at September 30, 2025. The weighted average exercise price of vested stock options is $1.81, and the average remaining contractual life is 2.57 years.

The fair value of each option granted is estimated on the date of grant using the Black-Scholes option pricing model. The weighted average assumptions and resulting fair values are as follows:

b. Restricted Share Units

The Company granted restricted share units ("RSUs") in accordance with the RSU plan approved at the June 17, 2021 shareholders meeting. These RSUs vest in three equal tranches: Tranche one - on completion of 12 months from grant date, Tranche two - on completion of eighteen months from the grant date and Tranche three - on completion of twenty-four months from grant date. These RSUs are classified as equity-settled as these awards will be settled by issuing the shares and are valued at the market price of the Company shares on the date of grant. As at September 30, 2025, the Company could grant an additional 4,427,078 RSUs under the RSU Plan. A summary of the Company's RSUs outstanding and the changes for the periods then ended, is presented below:

In relation to RSUs, the Company recognized an expense of $231,824 and $781,157 for the three and nine months ended September 30, 2025, respectively (three and nine months ended September 30, 2024 - $215,210 and $553,895, respectively) in the statements of loss and comprehensive loss. During the three and nine months ended September 30, 2025, $90,687 and $381,839 respectively, was capitalized, (three and nine months ended September 30, 2024 - $20,720 and $96,967, respectively) in the exploration and evaluation assets.

c. Deferred Share Units

Only directors of the Company are eligible for deferred share units ("DSUs") and each DSU vests immediately and is redeemed upon a director ceasing to be a director of the Company.

During the six months ended June 30, 2025, 197,444 deferred share units were settled by way of cash, rather than the issuance of shares. The aggregate cash payment owing of $359,348 was net against the cash proceeds receivable from a concurrent option exercise of $282,000 (Note 9a), resulting in a net cash payment to the holder of $77,348.

10. KEY MANAGEMENT COMPENSATION

The Company's key management includes its directors and officers. The remuneration of key management was as follows:

Share-based payments represent the fair value of vested stock options, RSUs and DSUs previously granted to directors and officers during the periods presented above.

During the three and nine months ended September 30, 2025, the Company recorded a bonus accrual of $181,501 and $544,504, respectively, which is recorded in salaries and director fees above. There was no bonus accrual recognized during the three and nine months ended September 30, 2024.

During the three and nine months-ended September 30, 2025, the Company paid fees of $33,369 to a company controlled by a director of the Company for consulting services related to permitting activities for the Casino Project. There were no such fees incurred during the three and nine months ended September 30, 2024.

12. SEGMENTED INFORMATION

The Company's operations are in one segment: the acquisition, exploration, and future development of mineral resource properties.  All interest income is earned in Canada and all assets are held in Canada.

13. SUPPLEMENTAL CASH FLOW INFORMATION

Non-cash working capital items

14. CAPITAL MANAGEMENT

The Company considers capital to be equity composed of share capital, contributed surplus, and deficit.  It is the Company's objective to safeguard its ability to continue as a going concern so that it can continue to explore and develop mineral resource properties. 

The Company monitors its cash position on a regular basis to determine whether sufficient funds are available to meet its short-term and long-term corporate objectives, and makes adjustments to its plans for changes in economic conditions, capital markets and the risk characteristics of the underlying assets. 

To maintain its objectives, the Company may attempt to issue new shares, seek debt financing, acquire or dispose of assets or change the timing of its planned exploration and development projects.  There is no assurance that these initiatives will be successful. 

There was no change in the Company's approach to capital management during the period.  Western has no debt and does not pay dividends. The Company is not subject to any externally imposed capital restrictions.

15. FINANCIAL INSTRUMENT RISK

The Board of Directors has overall responsibility for the establishment and oversight of the Company's risk management framework. The Company has exposure to liquidity, credit, and market risk from the use of financial instruments. Financial instruments consist of cash and cash equivalents, short-term investments, marketable securities, certain other assets, and accounts payable and accrued liabilities.

a. Liquidity risk

Liquidity risk is the risk that the Company will be unable to meet its financial obligations as they come due. The Company uses cash forecasts to ensure that there is sufficient cash on hand to meet short-term business requirements. Cash is invested in redeemable GICs, which are highly liquid investments and available to discharge obligations when they come due. The Company does not maintain a line of credit.

b. Credit risk

Financial instruments that potentially subject the Company to credit risk consist primarily of cash and cash equivalents and short-term investments. These financial instruments are at risk to the extent that the institutions issuing or holding them cannot redeem amounts when they are due or requested.  To limit its credit risk, the Company uses a restrictive investment policy. Cash and cash equivalents and short-term investments are held with high quality financial institutions. Substantially all cash and cash equivalents and short-term investments held with financial institutions exceeds government-insured limits. We have established credit policies that seek to minimize our credit risk by entering into transactions with investment grade credit worthy and reputable financial institutions. The carrying amount of financial assets, other than marketable securities, recorded in the financial statements represents Western's maximum exposure to credit risk.

c. Market risk

The Company is exposed to market risk because of the fluctuating values of its publicly traded marketable securities. The Company has no control over these fluctuations and does not hedge its investments. Marketable securities are adjusted to fair value at each balance sheet date. A 10% fluctuation in value of its publicly traded marketable securities rate would have a minimal impact on the Company's loss and comprehensive loss.

As at September 30, 2025, the carrying amounts of cash and cash equivalents, short-term investments, and accounts payable and accrued liabilities are considered to be reasonable approximations of their fair values due to the short-term nature of these instruments. The fair value of the marketable securities is determined by reference to published price quotations in an active market (classified as level 1 in the fair value hierarchy).

d. Interest rate risk

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate due to changes in market interest rates. The Company's financial assets and liabilities are not exposed to interest rate risk due to their short-term nature and maturity. Cash and equivalents and short-term investments are subject to fixed interest rates. The Company is not subject to interest rate risk.

CASINO PROJECT UPDATE

Permitting and Submission of the Environmental and Socio-economic Effects Statement ("ESE Statement")

On October 6, 2025, the Company announced the submission of its ESE Statement for the proposed Casino Project to the Yukon Environmental and Socio-economic Assessment Board ("YESAB").

The submission is an important step in the Panel Review process under the Yukon Environmental and Socio-economic Assessment Act ("YESAA"), representing a significant positive step in the permitting process for Casino.

The ESE Statement details the assessment of potential Project-related and cumulative environmental and socio-economic effects for Valued Environmental and Socio-economic Components ("VESECs"). With the implementation of a comprehensive suite of environmental management measures, including mitigation measures, management and monitoring plans, and an adaptive management approach, Project-related residual effects and any cumulative residual effects were assessed to be not significant across all VESECs.

The next step will involve a sufficiency check by YESAB's Executive Committee to confirm that the ESE Statement meets the ESE Statement Guidelines, as well as other preparatory steps by YESAB to formally establish the Panel of the Board, which will conduct a comprehensive assessment of the Project.

Economic Impacts of the Casino Project

The Company engaged MNP LLP, a Canadian accounting and consulting firm, to conduct updated economic impact modeling that quantifies Casino's direct, indirect, and induced economic effects across Canada.

Study Highlights (at US$3.60/lb Cu and US$1,700/oz Au):

- Economic Growth: Over its proposed 27-year mine life, Casino is estimated to contribute over C$44 billion to Canada's GDP, including over C$37 billion in the Yukon.

- Job Creation: Casino would directly employ approximately 700 workers and create an additional 2,000 jobs across suppliers, contractors, and local businesses, generating over C$12 billion in wages and salaries over the mine life.

- Government Revenues: Each year, Casino is forecasted to generate C$175 million in tax revenue for the Government of Yukon and C$231 million for the Government of Canada.

- Critical Minerals Production in Canada: Casino is positioned to become one of North America's largest producers of copper and molybdenum - both included on Canada's official list of critical minerals, with copper designated as one of six priority critical minerals essential for economic growth.

Infrastructure

The Company continues to provide updates on infrastructure initiatives supporting the development of Casino Project, including the B.C.-Yukon Grid Connect Project, Yukon Resource Gateway Project, and the Port of Skagway Transportation Study.

B.C.-Yukon Grid Connect Project:

On September 17, 2024, Natural Resources Canada ("NRCan") conditionally approved $40 million in funding to advance pre-feasibility work for a high-voltage transmission energy corridor connecting the isolated Yukon electrical grid to the North American grid in British Columbia (the "Grid Connect"). Western is pleased to report that the conditions for this funding have been met by the Yukon Development Corporation ("YDC"), an entity of the Government of Yukon, which included a 25% YDC funding commitment over and above the $40 million from NRCan. Subsequently, a contribution agreement with NRCan was officially signed in Ottawa on February 14, 2025, where project planning activities have since commenced. With its significant industrial load, the Casino Project is central to the concept behind the Grid Connect - its advancement signals confidence in the Casino Project's potential and its role in shaping the Yukon's future infrastructure. While Western continues to advance LNG as the Casino Project's base case power solution, the Company looks forward to working alongside YDC and First Nations to help make the grid connection a success.

On October 1, 2025, YDC published a report on the shared benefits of the Grid Connect, noting that the project links Canada's northwest to the North American grid. The transmission line will electrify several diesel-reliant communities and significant critical mineral developments in the Yukon and B.C.'s Northwest Corridor.

Yukon Resource Gateway Project:

On March 22, 2025, the Government of Yukon announced the inclusion of the Dempster Highway in the Yukon Resource Gateway Project ("Gateway Project"), expanding the scope of the initiative to include Arctic security and regional connectivity. Whilst positive for the Yukon, a portion of funding previously allocated to the Casino Copper-Gold Access Road has been redirected to support this near-term priority. Western remains in close collaboration with the Yukon government, and discussions on future funding are expected to advance as the project moves through the environmental assessment process, which includes the road.

Port of Skagway Transportation Study: 

Western has completed an updated transportation study evaluating options for shipping concentrate from the Casino Project to the Port of Skagway ("Skagway"). The study, conducted in collaboration with the Municipality of Skagway and the Government of Yukon, assessed both bulk and containerized transportation methods, assessed infrastructure requirements at Skagway, and provided feasibility-level capital and operating cost estimates across multiple scenarios. Several promising transportation alternatives were identified, with costs broadly in-line with, or lower than, the Company's 2022 feasibility study estimates. The Municipality of Skagway at its Borough Assembly Meeting on August 21, 2025, re-iterated its support for the transportation study, mineral shipments and related permitting at Skagway.

Drilling Program

On March 27, 2024, the Company announced the results from the 2023 drilling program (the "Drill Program") on its wholly-owned Casino copper-gold-molybdenum deposit.  The Drill Program was developed by Western's Technical and Sustainability Committee, which is comprised of members from Western, Rio Tinto and Mitsubishi Materials.

The 2023 Drill Program consisted of seven holes for 2,244 m ranging from 130 m to 556 m in length.  The drill holes were located inside the current pit boundaries and were selected to provide a range of grades, host rocks, and mineralogy.  The drill holes were also selected to convert indicated resource to measured.

Results from the Drill Program continued to show the importance of the Core Zone wherein relatively higher grades are encountered.

The 2023 Drill Program also included 783 m of geotechnical and hydrogeological drilling designed by Knight-Piesold Consulting, which targeted the ground conditions of the proposed open pit, stockpiles, tailings management facility, heap leaching facility, new airstrip, and the proposed Ranney well site.

Metallurgical Program

On February 13, 2025, the Company announced results from a supplemental metallurgical program (the "Metallurgical Program") for the Casino Project.

The Metallurgical Program used drill core composites of material representing potential mill feed taken from the 2023 diamond drilling program with more variable copper, gold, and molybdenum levels than had been tested in previous drill campaigns and from a broader period of planned mining, The fifteen composites of approximately 200 kg were subjected to detailed mineralogy, comminution testing, flotation testing and detailed analysis of copper concentrates. Composite preparation and all metallurgical test work was completed at ALS Metallurgy in Kamloops, B.C.

Standard processing methods continue to produce good recoveries for copper and gold, consistent with previous metallurgical work. The program achieved significantly higher recoveries for molybdenum.

Casino would produce a high gold grade copper concentrate and a separate molybdenum concentrate. Both are expected to be highly marketable given the very low levels of impurities.

The outline of the Metallurgical Program and the review of the results were developed by Western's Technical and Sustainability Committee, which is comprised of members from Western, Rio Tinto and Mitsubishi Materials.

Feasibility Study

On June 28, 2022, the Company released the results of its Feasibility Study (the "Study") on its wholly-owned Casino copper-gold-molybdenum deposit.  The Study considered the Project being constructed as an open pit mine, with a concentrator processing 120,000 tonnes per day (t/d) to recover copper, gold, molybdenum and silver, as well as a 25,000 t/d oxide heap leach facility to recover gold, silver and copper.

The Study supersedes all previous studies and incorporates an updated mineral resource and mineral reserve with an effective date of June 13, 2022.  The Study examines the development of the Casino Project, which comprises the processing of 1.43 billion tonnes of Mineral Reserve for both the mill and heap leach, with deposition of mill tailings and mine waste in the Tailings Management Facility ("TMF") consistent with the design concepts considered during the Best Available Tailings Technology ("BATT") Study as a base case development.             

Unless otherwise indicated, all references to "$" are to Canadian dollars and references to "US$" are to United States dollars.

RESULTS

The Study indicates that the potential economic returns from the Project justify its further advancement and securing of the required permits and licenses for operation.

The financial results of the Study were developed under commodity prices that were based on analyst projections of long-term metal prices and a CAN$:US$ exchange rate of 0.80 ("Base Case" prices).

The following table summarizes the financial results:

MINERAL RESERVES

The Mineral Reserve estimate is based on an updated open pit mine plan and mine production schedule using commodity prices of US$3.25 per pound copper, US$1,700 per ounce gold, US$12.00 per pound molybdenum and US$22.00 per ounce silver.

All of the mineralization included in the Mineral Reserve estimate with respect to the Casino Project is contained on mineral titles controlled by Western.  The following table presents the Mineral Reserve that is the basis for this Study.

Notes:

1. The Mineral Reserve estimate has an effective date of June 13, 2022 and was prepared using the CIM Definition Standards (10 May 2014).

2. Columns may not sum exactly due to rounding.

3. Mineral Reserves are based on commodity prices of US$3.25/lb Cu, US$1550/oz Au, US$12.00/lb Mo, and US$22.00/oz Ag.

4. Mineral Reserves amenable to milling are based on NSR cutoffs that vary by time period to balance mine and plant production capacities.  They range from a low of $6.11/t to a high of $25.00/t.

5. NSR value for supergene (SOX and SUS) mill material is NSR (C$/t) = $73.63 x recoverable copper (%) + $40.41 x gold (g/t) + $142.11 x moly (%) + 0.464 x silver (g/t), based on recoveries of 69% gold, 52.3% molybdenum and 60% silver.  Recoverable copper = 0.94 x (total copper - soluble copper). 

6. NSR value for hypogene (HYP) mill material is NSR (C$/t) = $67.88 x copper (%) + $38.66 x gold (g/t) + $213.78 x moly (%) + $0.386 x silver (g/t), based on recoveries of 92.2% copper, 66% gold, 78.6% molybdenum and 50% silver.

7. Mineral Reserves amenable to heap leaching are based on an NSR cutoff of $6.61/t.

8. NSR value for leach material is NSR (C$/t) = $14.05 x copper (%) + $47.44 x gold (g/t) + $0.210 x silver (g/t), based on recoveries of 18% copper, 80% gold and 26% silver.

9. AuEq and CuEq values are based on prices of US$ 3.25/lb Cu, US$ 1550/oz Au, US$ 12.00/lb Mo, and US$ 22.00/oz Ag, and account for all metal recoveries and smelting/refining charges.

10. The NSR calculations also account for smelter/refinery treatment charges and payables.

On August 9, 2022, the Company filed a technical report titled "Casino Project, Form NI 43-101F1 Technical Report Feasibility, Yukon, Canada" with an effective date of June 13, 2022 (the "Report").  The Report summarizes the results of the Feasibility Study on the Casino copper-gold project, which results were first reported by the Company in a news release dated June 28, 2022.

RESULTS OF OPERATIONS

THREE MONTHS ENDED SEPTEMBER 30, 2025

Western incurred a loss of $890,292 ($0.00 per common share) for the three months ended September 30, 2025, compared to a loss of $680,737 ($0.00 per common share) over the same period in 2024. The scale and nature of the Company's activity have remained generally consistent throughout these periods, but a few items led to differences in the comparative figures, as follows:

The Company recorded a gain on marketable securities of $534,133 during the three months ended September 30, 2025, compared to $347,480 during the same period in 2024 as a result of increases to the share price of the marketable securities held by Western at each period end date.

Interest income recorded of $406,624 during the three months ended September 30, 2025, compared to interest income of $906,389 during the same period in 2024 as higher rate bearing investments matured in the current period.

Professional fees increased by $112,845 during the three months ended September 30, 2025, compared to the same period in 2024 due to an increase in accrued audit and related fees for 2025 year-end compared to the same period in 2024.

Wages and benefits decreased by $277,099 during the three months ended September 30, 2025, due to certain severance payments for employees in the comparative period.

NINE MONTHS ENDED SEPTEMBER 30, 2025

Western incurred a loss of $2,155,353 ($0.01 per common share) for the nine months ended September 30, 2025, compared to a loss of $5,328,202 ($0.03 per common share) over the same period in 2024. The scale and nature of the Company's activity have remained generally consistent throughout these periods, but a few items led to differences in the comparative figures, as follows:

The Company recorded a gain on marketable securities of $2,218,307 during the nine months ended September 30, 2025, compared to $198,320 during the same period in 2024 as a result of increases to the share price of the marketable securities held by Western at each period end date.

Interest income recorded $1,614,346 during the nine months ended September 30, 2025, compared to an interest of $1,885,148 during the same period in 2024 as higher rate bearing investments matured in the current period.

Professional fees decreased by $144,424 during the nine months ended September 30, 2025, compared to the same period in 2024 due to a decrease in legal activity.

Wages and benefits decreased by $1,260,923 during the nine months ended September 30, 2025, due to certain severance payments for employees and bonuses awarded to certain executives in the comparative period.

Share based payments decreased by $56,134, driven by timing, valuation, and recognition differences relating to the underlying share-based compensation grants.

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents totaled $10,400,485 as at September 30, 2025 (December 31, 2024 - $14,202,317).  Cash and cash equivalents and short-term investments totaled $55,383,540 as at September 30, 2025 (December 31, 2024 - $67,972,991). Western's net working capital (current assets less current liabilities) as at September 30, 2025 totaled $51,338,257 (December 31, 2024 - $66,851,141). 

Western is an exploration and permitting stage company. As at the date of this report, the Company has not earned any production revenue. It depends heavily on its working capital balance and its ability to raise funds through capital markets to finance its operations. Although the Company expects that the current cash and short-term investments on hand will be sufficient to fund anticipated operating activities in the next twelve months, it will require significant additional funding to complete the development and construction of the Casino mine. 

Operating activities

The significant components of operating activities are discussed in the Results of Operations section above. 

Financing activities

During the nine months ended September 30, 2025, the Company received $1,275,000 from the exercise of warrants, $1,857,084 from the exercise of options, and expended $62,252 on lease payments.

During the nine months ended September 30, 2024, the Company completed a bought deal public offering for gross proceeds of $45,999,999 and private placements for gross proceeds of $8,282,154.

During the nine months ended September 30, 2024, the Company received $3,465,000 from the exercise of stock options and expended $170,215 on lease payments.

The table below summarizes the actual use of proceeds incurred up to September 30, 2025, compared to the expected use of proceeds from the bought deal offering documents1:

The Company expects to incur the remaining permitting and engineering expenditures over the next 12 months.

Investing activities

Investing activities include both mineral property expenditures, and purchases and redemptions of short-term investments. Investments with an original maturity of greater than three months are considered short-term investments for accounting purposes. Purchases and redemptions of short-term investments are mainly driven by cash requirements and available interest rates.

During the nine months ended September 30, 2025, the Company redeemed, on a net basis, $8,187,879 in short-term investments, as well as generated proceeds of $2,571,837 from the sale of marketable securities. Additionally, the Company spent $15,120,339 on exploration and evaluation assets and $50,075 on fixed assets purchases.

During the nine months ended September 30, 2024, the Company purchased, on a net basis, $51,197,377 in short term investments and spent $8,874,509 on exploration and evaluation assets. 

A summary of activities relating to the Casino Project is available under the Casino Project Update section at the beginning of this report.

OUTSTANDING SHARE DATA

As at the date of this report, the Company has 202,056,426 common shares outstanding. The Company also has 6,664,963 stock options outstanding with exercise prices ranging from $1.11 to $2.22, 1,285,555 restricted share units and 493,820 deferred share units to be settled by way of common shares issued from treasury.

The Company has no off-balance sheet arrangements and no long-term obligations other than those described throughout this document, or in the description of exploration and evaluation assets contained in the notes to the consolidated financial statements.

KEY MANAGEMENT COMPENSATION

The Company's key management includes its directors and officers. The remuneration of key management during the periods presented was as follows:

Share-based payments represent the fair value of stock options, RSUs and DSUs previously granted to directors and officers during the periods presented above. Salaries and share-based payments for certain officers are capitalized in exploration and evaluation assets and the balance is recognized in the statement of loss and comprehensive loss.

During the three and nine months ended September 30, 2025, the Company recorded a bonus accrual of $181,501 and $544,504, respectively, which is recorded in salaries and director fees above. In the comparable period, figures included certain severance payments for employees and bonuses awarded to certain executives.

During the three and nine months-ended September 30, 2025, the Company paid fees of $33,369 to a company controlled by a director of the Company for consulting services related to permitting activities for the Casino Project. There were no such fees incurred during the three and nine months ended September 30, 2024.

SIGNIFICANT ACCOUNTING ESTIMATES

Use of estimates and judgements

The preparation of financial statements in conformity with IFRS accounting standards requires to exercise judgement in the process of applying its accounting policies and to make estimates that affect the reported amounts of assets and liabilities and disclosures of contingent assets and contingent liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates. Differences may be material.

Exploration and evaluation assets

The carrying amount of the Company's exploration and evaluation assets represents costs net of write-downs and recoveries to date and does not necessarily reflect present or future values.  Recovery of capitalized costs is dependent on successful development of economic mining operations or the disposition of the related mineral properties. 

The Company's assets are reviewed for indication of impairment at each balance sheet date.  If indication of impairment exists, the assets' recoverable amount is estimated.  If the assets' carrying amount exceeds the recoverable amount, then an impairment loss is recognized in the statement of loss. The Company's review did not identify any indication of impairment.

Judgment is required in assessing whether a mineral property is in the exploration and evaluation phase and should be classified as an exploration and evaluation asset or if the exploration and evaluation phase has been completed and the mineral property should be reclassified as property and equipment. We determined that although a feasibility study for the Casino Project has been completed, the Company has not yet received the necessary licenses and permits required to consider the exploration and evaluation stage to have been completed.

ADOPTION OF NEW AND REVISED STANDARDS AND INTERPRETATIONS

Amendments to IFRS 9 and IFRS 7 - Amendments to the Classification and Measurement of Financial Instruments 

In May 2024, the IASB issued Amendments to the Classification and Measurement of Financial Instruments (Amendments to IFRS 9 and IFRS 7). These amendments updated classification and measurement requirements in IFRS 9 Financial Instruments and related disclosure requirements in IFRS 7 Financial Instruments: Disclosures. The IASB clarified the recognition and derecognition date of certain financial assets and liabilities, and amended the requirements related to settling financial liabilities using an electronic payment system. It also clarified how to assess the contractual cash flow characteristics of financial assets in determining whether they meet the solely payments of principal and interest criterion, including financial assets that have environmental, social and corporate governance (ESG)-linked features and other similar contingent features. The IASB added disclosure requirements for financial instruments with contingent features that do not relate directly to basic lending risks and costs and amended disclosures relating to equity instruments designated at fair value through other comprehensive income. 

The amendments are effective for annual periods beginning on or after January 1, 2026, with early application permitted.  Management is currently assessing the effect of these amendments on our financial statements.

IFRS 18 - Presentation and Disclosure in Financial Statements

In April 2024, the IASB issued IFRS 18, Presentation and Disclosure of Financial Statements (IFRS 18), which replaces IAS 1, Presentation of Financial Statements. IFRS 18 introduces a specified structure for the income statement by requiring income and expenses to be presented into the three defined categories of operating, investing and financing, and by specifying certain defined totals and subtotals. Where company-specific measures related to the income statement are provided, IFRS 18 requires companies to disclose explanations around these measures, which are referred to as management-defined performance measures. IFRS 18 also provides additional guidance on principles of aggregation and disaggregation which apply to the primary financial statements and the notes. IFRS 18 will not affect the recognition and measurement of items in the financial statements, nor will it affect which items are classified in other comprehensive income and how these items are classified. The standard is effective for reporting periods beginning on or after January 1, 2027, including for interim financial statements.

Retrospective application is required, and early application is permitted. Management is currently assessing the effect of this new standard on our financial statements.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for designing, establishing, and maintaining a system of internal control over financial reporting ("ICFR") to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in Canada.

The President & CEO and the CFO assessed the design and operating effectiveness of the Company's internal control over financial reporting as of December 31, 2024 and determined that it's ICFR was effective as of December 31, 2024.

In making this assessment, the Company's management uses the criteria established by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in its 2013 Internal Control-Integrated Framework.

There has been no change in the Company's ICFR during the nine-months ended September 30, 2025, that materially affected or is reasonably likely to materially affect our internal control over financial reporting.

DISCLOSURE CONTROLS AND PROCEDURES

Management is responsible for designing, establishing, and maintaining a system of disclosure controls and procedures.  Disclosure controls and procedures are designed to provide reasonable assurance that material information relating to the Company is made known to management, particularly during the period in which the annual filings are being prepared and that information required to be disclosed by the Company in its annual filings, interim filings or other reports filed or submitted by it under securities legislation is recorded, processed, summarized and reported within the time periods specified in securities legislation.

The President & CEO and the CFO evaluated the effectiveness of the Company's disclosure controls and procedures as of December 31, 2024. Based on this evaluation, our President & CEO and CFO concluded that the design and operation of our disclosure controls and procedures were effective as at December 31, 2024 and as of September 30, 2025, there has been no material change in our disclosure controls and procedures.

FINANCIAL INSTRUMENT RISK

The Board of Directors has overall responsibility for the establishment and oversight of the Company's risk management framework.  The Company has exposure to liquidity, credit, and market risk from the use of financial instruments.  Financial instruments consist of cash and cash equivalents, short-term investments, marketable securities, and accounts payable and accrued liabilities.

Liquidity risk

Liquidity risk is the risk that the Company will be unable to meet its financial obligations as they come due.  The Company closely monitors its liquidity position and endeavours to ensure it has adequate sources of funding to finance its projects and operations.  Some of the Company's cash is invested in redeemable GICs, which are highly liquid investments and available to discharge obligations when they come due.  The Company does not maintain a line of credit.

Credit risk

Financial instruments that potentially subject the Company to credit risk consist primarily of cash and cash equivalents and short-term investments. These financial instruments are at risk to the extent that the institutions issuing or holding them cannot redeem amounts when they are due or requested.  To limit its credit risk, the Company uses a restrictive investment policy. Cash and cash equivalents and short-term investments are held with Schedule 1 chartered banks in Canada. Substantially all cash and cash equivalents and short-term investments held with financial institutions exceed government-insured limits. We have established credit policies that seek to minimize our credit risk by entering into transactions with investment grade credit worthy and reputable financial institutions. The carrying amount of financial assets, other than marketable securities, recorded in the financial statements represents Western's maximum exposure to credit risk.

Market risk

The Company is exposed to market risk because of the fluctuating values of its publicly traded marketable securities. The Company has no control over these fluctuations and does not hedge its investments. Marketable securities are adjusted to fair value at each balance sheet date.

Interest rate risk

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate due to changes in market interest rates. The Company's financial assets and liabilities are not exposed to interest rate risk due to their short-term nature and maturity. Cash and equivalents and short-term investments are subject to fixed interest rates. The Company is not subject to interest rate risk.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Information contained in this MD&A that are not historical facts are forward-looking information and forward-looking statements within the meaning of applicable securities legislation and involve risks and uncertainties (collectively, "forward-looking statements"). Certain forward-looking information may also be considered future-oriented financial information ("FOFI") as that term is defined in NI 51-102.  The purpose of disclosing FOFI is to provide a general overview of management's expectations regarding prospective financial performance, financial position or cash flows and readers are cautioned that the assumptions used in the preparation of such information, although considered reasonable at the time of preparation, may provide to be imprecise or inaccurate and, as such, undue reliance should not be placed on FOFI. Forward-looking statements include, but are not limited to, statements with respect to the future price of metals; the estimation of mineral reserves and mineral resources, the realization of mineral reserve estimates; the results of metallurgical testing programs; the timing and amount of any estimated future production, costs of production, and capital expenditures; project schedules; the Company's proposed plan for its properties, including the development of the Casino Project; recommended work programs; costs and timing of the development of new deposits; success of exploration and permitting activities; permitting timelines; currency fluctuations; requirements for additional capital; government policy between Canada and the United States, including potential tariffs and retaliatory tariffs, regulation of mineral exploration or mining operations; environmental risks; the review of the submitted Environmental and Socio-economic Effects Statement and the timing thereof; unanticipated reclamation expenses; title disputes or claims; limitations on insurance coverage; the timing and possible outcome of potential litigation; the potential advancement of a high-voltage transmission line network connecting the Yukon electrical grid to the North American grid in British Columbia; and the impact of potential global pandemics on the Company's business and operations. In certain cases, forward-looking statements can be identified by words such as "plans", "expects", "is expected", "budget", "scheduled", "estimates", "intends", "anticipates" or "does not anticipate", or "believes", or variations of such words and phrases or state that certain actions, events or results "may" or "may not", "could", "would" or "would not", "might" or "will be", "occur" or "be achieved". Such statements are included, among other places, under the heading "Casino Project Update" in this MD&A and may include, but are not limited to, statements regarding perceived merit of properties; mineral reserve and mineral resource estimates; exploration and evaluation expenditures; results of the Study (including projected economic returns, operating costs, capital costs and other financial results in connection with the Casino Project); cash flow forecasts; exploration results at the Company's properties; budgets; work programs; permitting and other timelines; the Company's engagement with local communities; estimated timing for construction of, and production from, any new projects; market price of precious and base metals; expectations regarding future price assumptions, financial performance; or other statements that are not statements of historical fact.

Forward-looking statements are necessarily based upon a number of estimates and assumptions, including material estimates and assumptions related to the factors set forth below that, while considered reasonable by the Company as at the date of this MD&A in light of management's experience and perception of current conditions and expected developments, are inherently subject to significant business, economic and competitive uncertainties and contingencies. The material assumptions used to develop the forward-looking statements herein include assumptions that (1) political and legal developments in jurisdictions where Western operates, or may in the future operate, being consistent with Western's current expectations, (2) prevailing and projected market prices and foreign exchange rates, exploitation and exploration estimates will not change in a materially adverse manner, (3) requisite capital and financing will be available on acceptable terms, (4) equipment and personnel required for permitting, construction and operations will be available on a continual basis, (5) no unforeseen disruptions or delays, unexpected geological or other effects, equipment failures, or permitting including any disruptions caused any future pandemics or any other unforeseen disruptions or delays that would have an adverse effect on Western's operations, (6) equipment, labour and materials costs increasing on a basis consistent with Western's current expectations, and (7) general economic, market or business conditions will not change in a materially adverse manner and as more specifically disclosed throughout this document, and in the AIF and Form 40-F. 

Forward-looking statements involve known and unknown risks, uncertainties and other factors, which may cause the actual results, performance or achievements of Western and its subsidiaries to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. Such risks and other factors include, among others, history of losses and negative operating cash flow; risks inherit to mineral exploration and development activities; uncertainties relating to interpretation of drill results and the geology, continuity and grade of mineral deposits; risks related to the potential loss of the Company's properties; uncertainty as to timely availability of permits and licenses and other governmental approvals; risks related to the Company's dependence on a single project; title risks; price fluctuations of the Common Shares; risks surrounding statutory and regulatory compliance; risks surrounding environmental laws and regulations; risks surrounding land reclamation costs; operational risks surrounding the remote location of assets; risks surrounding Western's ability to maintain its infrastructure; risks involved in fluctuations in gold, copper and other commodity prices; uncertainty of estimates of capital and operating costs, recovery rates, production estimates, and estimated economic return; changes in project parameters as plans continue to be refined; risks related to the cooperation of government agencies and Indigenous peoples in the exploration and development of Western's property; volatility in the price of metals; climate change risks; risks related to fluctuations in currency exchange rates; risks surrounding dilution of the Common Shares; dependence on members of management and key personnel; competition risks; inflation risks; risks related to macro-economic factors including global financial volatility; potential natural disasters, terrorist acts, health crises and future pandemics; risks related to the need to obtain additional financing to develop the Company's property and uncertainty as to the availability and terms of future financing; litigation risks; the possibility of delay in exploration or development programs or in construction projects and uncertainty of meeting anticipated program milestones; risks related to potential acquisitions and the integration thereof; risks related to operations; risks related to the feasibility study and the possibility that future exploration and development will not be consistent with the Company's expectations; risks related to joint venture operations; conclusions of economic evaluations; possible variations in mineral reserves, mineral resources, grade or recovery rates; insurance risk; reclamation costs; risks related to conflicts of interest; risks related to internal controls; tax risks, specifically related to the Company's classification as a "passive foreign investment company" under the meaning of Section 1297 of the U.S. Internal Revenue Code of 1986, as amended; failure of plant, equipment or processes to operate as anticipated; accidents, labour disputes and other risks of the mining industry; risks related to information technology and cybersecurity; risks related to regulatory compliance; the Company's history of not paying dividends; and risks related to shareholder activism; impact of any global pandemics and the Russian invasion of Ukraine; and other risks and uncertainties disclosed in the AIF and Form 40-F, each of which provide for a more detailed discussion of some of the factors underlying forward-looking statements and the risks that may affect the Company's ability to achieve the expectations set forth in the forward-looking statements contained in this MD&A.

Although Western has attempted to identify important factors that could affect it and may cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. Forward-looking statements may prove to be inaccurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. Western does not undertake any obligation to release publicly any revisions to these forward-looking statements to reflect events or circumstances after the date hereof to reflect the occurrence of unanticipated events unless required by applicable securities law.

Non-GAAP Measures and Other Financial Measures

Alternative performance measures in this MD&A, such as "cash cost" and "free cash flow", are used to provide additional information. These non-GAAP performance measures are included in this MD&A because these statistics are used as key performance measures that management uses to monitor and assess performance of the Company's property and to plan and assess the overall effectiveness and efficiency of mining operations. These performance measures do not have a standard meaning within IFRS accounting standards and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. These performance measures should not be considered in isolation as a substitute for measures of performance in accordance with IFRS accounting standards.

CAUTIONARY NOTE TO U.S. INVESTORS

The MD&A has been prepared in accordance with the requirements of the securities laws in effect in Canada as of the date of this MD&A, which differ in certain material respects from the disclosure requirements of United States securities laws.  The terms "mineral reserve", "proven mineral reserve" and "probable mineral reserve" are Canadian mining terms as defined in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") - CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended.  NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects.  The definitions of these terms and other mining terms, such as "inferred mineral resource," differ from the definitions of such terms, if any, for purposes of the disclosure requirements of the United States Securities and Exchange Commission (the "SEC"). 

Accordingly, information contained and incorporated by reference into this MD&A that describes the Company's mineral deposits may not be comparable to similar information made public by issuers subject to the SEC's reporting and disclosure requirements applicable to domestic United States issuers.
