en.Wedoany.com Reported - Zacatecas Silver has signed a definitive option agreement with subsidiaries of Heliostar Metals (Heliodor Metals and Minera Aurea) to acquire 100% interests in four exploration projects located in Sonora and Oaxaca, Mexico.

The transaction covers the Cumaro, La Lola, Oso Negro, and Ejutla projects, which are considered to have gold and silver exploration potential. Under the agreement, Zacatecas Silver will make staged payments totaling $450,000 in cash and $750,000 in company shares over the next three years. As part of the transaction closing, Heliostar has received an initial cash payment of $129,000 and has been issued 4,217,845 shares of Zacatecas Silver.
The transaction also allows Heliostar to retain a 2% net smelter return (NSR) royalty on the transferred projects, enabling it to benefit from future exploration and development progress. The new owner has the right to purchase 1% of this royalty for $2 million at any time before the commencement of commercial production.
Regarding asset potential, the Oso Negro project in Sonora is an undrilled intermediate sulfidation epithermal system, with prior sampling showing gold grades up to 13.3 g/t and silver grades up to 953 g/t. The project contains at least four main veins with an average width of approximately 3 meters, along with several secondary veins. The Cumaro project in Sonora covers a 5-square-kilometer area along the same trend as Coeur Mining's El Picacho asset, hosting extensions of low-sulfidation veins. The company plans to immediately initiate an intensive field mapping and sampling program. The La Lola project in Sonora comprises nine mining claims totaling approximately 1,183 hectares, offering regional-scale exploration potential. Its most prominent structure is the La Barra vein, a 5-kilometer-long quartz-carbonate-fluorite vein with exposed widths of up to 40 meters. This is an extensive and underexplored system that will be the focus of an initial intensive rock chip sampling and mapping program. The Ejutla project in Oaxaca covers 10,603 hectares adjacent to the San José mine. The region has a diverse metallogenic history containing multiple deposit types, with potential for hosting precious metal mineralization associated with low-sulfidation epithermal systems and Carlin-type gold mineralization.
