Sinda ^{Filed, US Offering, NYSE: SIND}

We hold title to, or have exploration and exploitation rights on, five contiguous mining concessions covering a large-scale, high-grade, silver-gold greenfield discovery located in the historic Guanajuato epithermal silver belt of Mexico. The Sinda Property is a large primary silver asset that we believe has the potential to be a globally significant mining operation. The Sinda Property is located approximately 22 miles (35 kilometers) from the colonial city of San Miguel de Allende in the Mexican state of Guanajuato, approximately 180 miles (290 kilometers) northwest of Mexico City and 28 miles (45 kilometers) southeast of the Guanajuato Mining District, in close proximity to several of the world’s largest and historically most productive silver deposits and mines. The location of the Sinda Property provides access to existing regional infrastructure and an established labor force to support current and future exploration and mining activities. Mexico is the world’s top silver mining jurisdiction, accounting for approximately 20% of all global mined silver production in 2025. Recent policy shifts in Mexico have reignited investment and exploration, and we expect that this will provide a positive backdrop for our exploration and development plans. Large primary silver assets such as the Sinda Property are rare, with only approximately 28% of global mined silver supply coming from primary silver mines in 2024.
