PRESS RELEASE

SMX ANNOUNCES THE SUCCESSFUL COMPLETION OF PROOF OF CONCEPT FOR ETHICAL SOURCING AND AUTHENTICATION OF SILVER IN COOPERATION WITH SMI

New York, April 15, 2024 – SMX (Security Matters) PLC (NASDAQ: SMX; SMXWW), a pioneer in digitizing physical objects for a circular economy, has announced today the successful completion of proof of concept for ethical sourcing and authentication of silver in cooperation with SMI.

SMX have now successfully completed the marking of 2.2 tons of silver within SMI’s operations. The program covered the marking of the silver raw material through continuous manufacturing processes to final products including recycling loops.

The SMX technology was added at the melting stage and the marked silver material was processed into blank (from casting, extrusion, rolling, annealing, blank cutting & recycling), and the quality of the marked intermediate material and final products was evaluated (from billet to blank and recycled blank after several cycles).

The results demonstrated 100% success rates on all marked products all along the production process (from billet to finished product) ensuring the durability and irrefutable proof of quality and Brand authentication of the silver for credible ESG reporting for stakeholders, customers, auditors, and regulators.

Success

Outcomes

SMX successfully implemented its Marking System across several batches of the silver at the melting stage and was able to differentiate marked from unmarked silver material, providing Brand authentication of the silver material.

SMX Marking System was successfully detected throughout the silver production process from melting, casting, hot & cold rolling, annealing to blank cutting & recycling, demonstrating its durability and traceability functionality.
