Bitfarms Mines 411 BTC in September 2023

- Fully energizes Rio Cuarto at 51 MW, expanding total operating capacity to 233 MW -

- Increases hashrate 9% to 6.1 EH/s -

- Improves energy efficiency to 36 w/TH with new 28 w/TH miners -

Toronto, Ontario and Brossard, Québec (October 2, 2023) - Bitfarms Ltd. (NASDAQ: BITF//TSX: BITF), a global vertically integrated Bitcoin mining company, provides a Bitcoin (BTC) production and mining operations update for September 2023.

“In September, we continued to install new miners and fully energized Rio Cuarto to 51 MW, increasing our operating capacity by 9% to 233 MW. Year-to-date, we increased operating capacity by 24% and upgraded and expanded our fleet with over 15,000 additional miners,” said Geoff Morphy, CEO of Bitfarms. “Also in September, our hashrate increased 9% to 6.1 EH/s, slightly below our Q3 2023 target of 6.3 EH/s reflecting some electrical infrastructure delays that pushed out the Baie-Comeau, Québec facility’s full installation by a couple of weeks.”

“We continue to believe that many of our best opportunities for growth and investment will arise around the next Bitcoin halving expected to occur in April 2024. To this end, we are focused on infrastructure and balance sheet strength to provide the financial flexibility to move aggressively when conditions for growth are optimal. We continued to pay down debt, closing September with under $10 million of outstanding indebtedness, all of which is scheduled for repayment in advance of the halving,” added Morphy.

Ben Gagnon, Chief Mining Officer of Bitfarms, said, “As the farm in Argentina became fully energized, our BTC production was 411 in September, up 7.3% from August 2023 even with a 2.7% network difficulty increase in the month.”

“Executing on our comprehensive fleet management strategy, we have further optimized our miner portfolio while bolstering our balance sheet in anticipation of purchasing the next generation of sub-20 w/TH miners after the halving. The September installation of S19 Pro + miners in Argentina nearly doubled the number of sub-30 w/TH miners in operation and shifted the fleet portfolio constitution; it is now comprised of 23% sub-30 w/TH miners, 58% 30-40 w/TH machines and 19% 40-45 w/TH machines. As expected, we are now well positioned to leapfrog over the XP generation entirely and strategically layer in the new sub-20 w/TH miners for both upgrades and expansion. The recently announced new generation of sub-20 w/TH miners have the capability to rapidly drive hashrate growth and increase energy efficiency around halving at significantly lower costs per TH than XP miners have traded for throughout 2023,” concluded Gagnon.

Mining Review

Due to the added corporate capacity supplemented by the moderate weather in North America that minimized curtailment and facilitated uptimes, September production of 411 BTC rose 7.3% from the 383 BTC mined in August, which included an extra day of production.

Network difficulty increased 2.7% in September compared to August, as Bitcoin miners anticipating higher Bitcoin prices continue to invest in capacity and come online. For the nine months ended September 30th, network difficulty increased 61.5% while the BTC price was up roughly 63.2%, resulting in a 3.6% improvement in mining economics as measured by USD/TH/day.
