Copper Standard Announces Commencement of Drilling at Colpayoc Project

In This Article:

Vancouver, British Columbia--(Newsfile Corp. - April 3, 2024) - Copper Standard Resources Inc. (CSE: CSR) ("Copper Standard" or the "Company") announces the commencement of drilling at its flagship Colpayoc Project in the Yanacocha Mining District in Cajamarca, Peru.

The Company has started Phase I of a two-phase drill program. Phase I is expected to include approximately 16,400 feet (5,000 meters) of drilling over 18 drill holes to test the potential large copper/gold porphyry and expand the existing resource. The Company anticipates completion of the Phase I drill program by mid-2024. Phase II to be based upon Phase I results. The Company's proposed drill program stems from the expansion of geologic knowledge and understanding of the deposit attained through the relogging of historical drill core and complementary detailed fieldwork.

During detailed geologic reviews, the Company identified a potential porphyry copper/gold target underlying the previously drilled oxide gold cap. The gold cap contains over 300,000 ounces of an inferred gold resource and remains open both laterally and at depth. Average drill hole depth will be approximately 655 feet (200 meters) where drilling is designed to confirm and expand the current oxide gold resource. At least two drill holes are expected to reach depths of approximately 1,300 feet (400 meters) to test for the enriched copper and copper-gold primary grades in the untested porphyry system underlying the Daylight oxide gold resource.

These programs are fully funded for 2024 with the completion of the Company's recently over-subscribed $5 million private placement.

Andy Swarthout, Chairman, commented "2024 represents a significant opportunity for Copper Standard, and we look forward to expanding our gold resource as we test the extent of the underlying porphyry system. Previous drilling ended in phyllic alteration with anomalous gold and copper, indicating potential proximity to a porphyry copper/gold system. Phase I drilling will not only establish the potential of the oxide gold mineralization at depth but will provide important guidance for expanded exploration of the underlying porphyry system in Phase II drilling."
