Ridgestone Mining Inc. announced assays results from the recently completed mapping and routine sampling program at its wholly-owned Rebeico copper-gold project in Sonora State, Mexico. The program, which was comprised of geologic mapping, prospecting and sampling, was completed in May 2021. The program focused on an area around the past producing El Cobre copper mine as well as an approximately 5.25 square-kilometre area within the Rebeico concessions. Highlights: El Cobre: sampling from the mineralized structure outcropping on surface returned up to 3.5% copper over 1.0 metres, with sampling from the historic dumps ranging from 2.01 to 2.65% copper. Regional: Multiple mineralized structures and artisanal workings were encountered, with sampling returning up to 3.11% copper and up to 3.45 g/t gold from surface. Permitting: Permitting underway for a drill program to test the high-priority copper targets, including the El Cobre mine. Geological Model: Geological mapping has revealed mineralized breccias within and peripheral to volcanic intrusive rocks, contact skarns and hornfels within the sedimentary carbonate and siltstone rocks where they were in contact with volcanic intrusive rocks which are typical for a copper-gold porphyry system.
