ON MEXICO ISSUES

• Vizsla Silver Corp., announced that it has resumed all field work activities at its Panuco project in Sinaloa due to improvement of the security conditions in the region. Ongoing programs include test mine development, geotechnical drilling, exploration drilling, mapping and geophysical surveys.
• Carlos Pavón Campos, leader of the Miners' Union "Frente", asserted that the USD $55M in question belongs to the workers, confirmed by a recent ruling against the union led by Napoleón Gómez Urrutia. Pavón who worked with Napoleón Gómez Urrutia point out that the judicial process has removed Grupo Mexico and Scotiabank from the trust, leaving the responsibility solely with the union. He highlighted that the ruling mandates the union to cover any payment discrepancies for workers who received between MXP $60-80K. He also mentioned that the three emblematic strikes, which have lasted almost 18 years, are no longer effective. In Cananea, workers have returned to work and many have already been paid. In San Martín, Zacatecas, most have also returned to work, and in Taxco, Guerrero, the company had requested the termination of the collective bargaining agreement due to the lack of mineral reserves. Pavón emphasizes that the workers still waiting to return are in a precarious situation, as the mine has no reserves and many of the original workers have aged or passed away.
