Carolina Rush Intersects Copper-Gold Mineralization Below Lithocap at Brewer, Confirming Copper-Gold Porphyry System
Carolina Rush tests a deep porphyry target at the Brewer project as OceanaGold’s earn-in agreement continues to progress.
Carolina Rush Corporation (RUSH) has released drilling results from Hole 38 at its Brewer Gold-Copper Project, marking the first intersection of copper-gold mineralization below the project's extensive lithocap. The hole intersected broad zones of anomalous copper-gold mineralization, including:
- 60m @ 681 ppm Cu and 0.24 g/t Au
- 68m @ 470 ppm Cu and 0.15 g/t Au
These results provide direct evidence of porphyry-style alteration and mineralization, dominated by chalcopyrite within chlorite and minor potassic alteration. The geological model confirms a structurally tilted porphyry system, with the higher-temperature core interpreted to be down-dip to the northwest and currently untested.
Hole 38 is the second of three deep holes drilled under the OceanaGold earn-in agreement, with assay results for Hole 39 pending. OceanaGold satisfied its Q2 2026 minimum commitment of $1.5M and must fund a total of $8M by December 31, 2027, to earn a 50% interest.
Carolina Rush Corporation (RUSH) has released results that represent an expected, incremental step in its deep drilling program, which commenced in January 2026. The findings validate the company's geological model and provide a clear vector toward the untested porphyry core, though they do not constitute a discovery or a change in the fundamental risk profile.
The results align with previous expectations set by the Hole 37 release in May 2026 and the initial partnership announcement, with no surprises in grade, geometry, or partnership terms. Market reaction has been muted, with the stock price declining from approximately $0.13 in early June to $0.09, indicating that investors view this development as routine progress rather than a market-moving event.
Carolina Rush Corporation (RUSH) is a junior explorer focused on the Brewer Gold-Copper Project in Jefferson, South Carolina. The project sits approximately 13 km from OceanaGold's Haile gold mine and sits atop a historic high-sulfidation epithermal system.
The company’s maiden mineral resource estimate for 2025 includes an Indicated resource of 192 koz Au and 16.7 Mlbs Cu, alongside an Inferred resource of 210 koz Au and 8.3 Mlbs Cu. The current exploration phase targets a deep porphyry Cu-Mo-Au system beneath the lithocap, utilizing deep diamond drilling to test the structural geometry.
