Questcorp and Riverside Make New Gold Discovery in Initial Drill Results from Luis Hill and Famosa Targets at Union Project, Sonora, Mexico

Core Insights - Questcorp Mining Inc. and Riverside Resources Inc. announced a new discovery of Carlin-like gold mineralization at the Luis Hill target within the La Union Project in Sonora, Mexico [1][4] - Initial drilling at Luis Hill returned a significant intersection of 42 meters at 0.3 g/t gold, indicating a new style of mineralization not previously recognized at the project [2][5] Drill Program Highlights - The initial drill program included 12 core holes totaling over 1,600 meters across six targets, including the past-producing Union, Union Norte, and Famosa Mine [5] - Assays are pending for over 700 half-core samples from various targets, including Union, Union North, and Cobre [5] - The drilling strategy focused on angled and near-vertical holes to intersect typical Carbonate Replacement Deposit (CRD) systems, targeting depths generally less than 150 meters [5] Discovery Details - The discovery at Luis Hill included 23 assay intervals ranging from 0.005 g/t to 1.31 g/t gold, with 15 intervals exceeding 0.1 g/t and three exceeding 0.5 g/t [10] - The mineralization type found at Luis Hill is aligned with a carbonate-hosted metal system, which is significant for the region's geological context [5][9] Future Plans - The companies plan to organize a Phase 2 exploration program for H1 2026, which will build on the results from Phase 1 and include follow-up drilling, geophysics, geochemistry, and mapping [26][27] - The next set of drill results will be released following a QA/QC review [27] Strategic Orientation - The sediment-hosted gold style found at Luis Hill is comparable to Nevada's carbonate platform geology, indicating potential for further exploration in the Sonora Gold Belt [23] - The companies are optimistic about the potential for Luis Hill to become a major new discovery in Mexico, with plans for continued exploration in the area [9][26]
