Carolina Rush (TSXV:RUSH) - First Drill Confirmation of Copper-Gold Porphyry System at Brewer

Interview with Layton Croft, President & CEO, Carolina RushOur previous interview: https://www.cruxinvestor.com/posts/carolina-rush-tsxvrush-testing-deep-porphyry-potential-in-americas-first-gold-district-9470Recording date: 1st July 2026Carolina Rush has completed the first deep drilling program at its Brewer Gold-Copper project in South Carolina, confirming the presence of a copper-gold porphyry system beneath its historic near-surface gold mine. The program, consisting of three deep holes totaling 3,500 metres, marks a significant shift in the company’s exploration focus from shallow gold mineralisation to a larger, deeper target.Results from hole 37 provided early indications of a porphyry system, including elevated copper levels, the presence of chalcopyrite, and characteristic quartz veining. More importantly, hole 38 delivered a breakthrough by intersecting copper-gold mineralisation beneath the lithocap for the first time. The hole returned multiple mineralised intervals, including 60 metres grading 681 ppm copper and 0.24 g/t gold within potassic alteration, a zone typically associated with the core of porphyry deposits.A revised geological model, developed with porphyry expert Dr. Richard Sillitoe, suggests the system is tilted 20–30 degrees to the northwest rather than vertical. This interpretation implies that the mineralised core may lie at a shallower and more economically accessible depth than previously assumed.The project is being advanced through an earn-in agreement with OceanaGold, which must invest US$8 million by the end of 2027 to earn a 50% stake. Carolina Rush remains the operator, while OceanaGold brings funding and regional infrastructure, including its nearby Haile gold mine.With a defined near-surface resource of approximately 500,000 ounces of gold and growing evidence of deeper porphyry potential, Brewer represents a dual-opportunity asset. Assay results from the third hole are pending, and further drilling is planned to test the system along its interpreted northwest extension.Learn more: https://www.cruxinvestor.com/companies/carolina-rushSign up for Crux Investor: https://cruxinvestor.com
