Questcorp and Riverside Lock Down Key Sonora Mineral Concessions

FULL DISCLOSURE: Canacom Group is long the equity of Questcorp Mining and Riverside Resources.

Questcorp Mining (CSE: QQQ) and Riverside Resources (TSXV: RRI) have finalized a deal to consolidate a strategic slice of the La Union Project in Sonora, Mexico, securing full control over three key mineral concessions in the Famosa area just as the spring exploration season kicks off.

The transaction marks the completion of a multi-year option agreement. Riverside’s Mexican subsidiary, RRM Exploración, made a final payment of $125,000 to Pacific Comox S.A. to trigger the transfer of the La Famosa, Dana 7, and Dana 7 titles. The $175,000 total acquisition comes entirely free of any net smelter royalties.

The newly acquired ground is more than just a footnote to the project’s footprint. These concessions sit in the southern portion of the La Union district, where the geology suggests potential for carbonate replacement deposit style mineralization and structurally controlled polymetallic mineralization.

“Securing these concessions with no royalty burden enhances the project’s long-term potential,” said Saf Dhillon, President and CEO of Questcorp. The company’s partner, Riverside, echoed the sentiment, noting that the consolidation provides greater flexibility for the upcoming 2026 exploration program.

The timing is deliberate. With titles now secured through 2044 and 2053, the partners have a decades-long runway to explore and develop. The focus now shifts to the drill bit, as Questcorp and Riverside look to prove that the concessions hold the same metallic promise as neighboring projects in the prolific Sonora region.

This confidence is backed by high-grade data already coming out of the project. Recent results from the Union Mine area delivered a standout continuous chip channel sample of 30 meters grading 20.2 g/t gold and 226 g/t silver. These gram-metre figures suggest significant mineralization remains in place within the historical workings.

Beyond the known silver-gold-zinc targets, the team has stumbled upon a potential Carlin-style surprise. Drilling at the Luis Hill target intersected 42 meters of 0.3 g/t gold in black shales—a geological signature more commonly associated with Nevada’s massive sediment-hosted deposits than this part of Sonora, suggesting a potential disseminated gold target exists.

Questcorp Mining last traded at $0.145 on the CSE.
