Zacatecas Silver Corp. has announced a definitive option agreement to acquire a 100% interest in the Cumaro, La Lola, Oso Negro, and Ejutla exploration properties from Heliostar Metals Ltd. The properties are located in Sonora and Oaxaca, Mexico, and represent a significant expansion of Zacatecas Silver's Mexican growth platform.
Highlights of the Acquisition
The Oso Negro property presents a compelling, undrilled high-grade discovery opportunity with high-grade gold and silver across multiple multi-metre vein systems. The Cumaro property is strategically positioned along strike from Coeur Mining's active El Picacho development, hosting extensions of proven low-sulphidation epithermal vein systems. La Lola offers district-scale exposure with a 5 km vein system up to 40 metres wide, while Ejutla adds a substantial 10,603-hectare land position near the San Jose Mine, hosting multiple high-level epithermal veins and potential Carlin-style mineralisation.
Transaction Terms
Under the definitive agreement, Zacatecas Silver must pay US $450,000 to Heliostar in staged payments over three years, and issue US $750,000 in common shares to Heliostar over the same period. The initial payment of US $150,000 and issuance of US $300,000 in shares have been partially completed.
This acquisition significantly strengthens Zacatecas Silver's position in premier mining jurisdictions in Mexico, providing exposure to high-grade gold and silver exploration opportunities with strong depth potential.
