VANCOUVER – Riverside Resources has optioned its Los Cuarentas project, in Sonora, Mexico, to Hochschild Mining in a deal that will see the major spend U$8 million over five years to earn an initial 51% interest.

The prospect generator has defined several targets at the gold-silver project, which is located 17 km northwest of SilverCrest Metals‘ Las Chispas project and 15 km northeast of Premier Gold Mines‘ Mercedes mine.

Riverside believes the past-producing project, which supported near-surface underground mining in the 1950s, has potential to host a near-surface, high-grade gold vein system. The company received drill permits for the project, which has not seen any known drilling to date, in April.

Once Hochschild has earned a 51% interest in Los Cuarentas, it can earn another 24% (for 75%) by spending US$3 million and completing a feasibility study. It can then buy the remainder of the project for US$20 million. Riverside would retain a 1% net smelter royalty.

Under the earn-in agreement, Riverside will remain operator for at least the first two years. Hochschild can extend that for another year.

Through a sampling and target mapping program completed earlier this year, Riverside has identified three well-defined targets for drilling at Los Cuarentas: Santa Rosalia, Santa Rosalia Sur and El Sombrero. It has also identified three new prospective targets: El Sombrerito, El Sombrero Norte and Santa Rosalia Norte.

Rock-chip samples from the 8-sq.-km project returned assay highlights including 18 g/t gold, 12.3 g/t gold, 7.3 g/t gold and 3 g/t gold.

The low-sulphidation epithermal gold-silver project hosts multiple gold-bearing quartz veins located within a larger structural corridor. Riverside says the sampling results indicate continuity along the principal mineralized zones.

According to the junior, Los Cuarentas has similar characteristics to other nearby gold-silver deposits, including strong argillic and phyllic alteration surrounding low-sulphidation epithermal vein systems that host the gold and silver mineralization.
