Carolina Rush Improves Commercial Terms of Brewer Option Agreement with Government

Carolina Rush Corporation has executed the Sixth Amendment to its Option Agreement for the Brewer Mine Property, fundamentally altering the financial structure of the deal. The estimated US$27 million purchase price is no longer due as a lump sum at closing. Instead, payment is restructured into 10 equal annual installments, contingent upon the full permitting of new mining operations by state and federal authorities.

Under the amended terms, financial assurance at closing can now be satisfied through five non-cash methods, referencing EPA guidelines for Superfund settlements. The company retains its existing NI 43-101 mineral resource estimates for the project. This amendment follows a completed initial three-hole deep drilling program and an adjacent land expansion at the Jefferson Project.

Carolina Rush Corporation (RUSH) has amended its Brewer acquisition agreement to eliminate immediate lump-sum cash outflows, tying payments instead to regulatory milestones. This change reduces upfront capital requirements through non-cash financial assurance options, preserving working capital for exploration activities. The amendment follows the September 2025 option agreement and aligns with standard negotiation practices for advancing a Superfund site. The adjustment does not alter the exploration stage, resource status, or immediate catalysts, representing an expected incremental step in project advancement. No new strategic investors or major financing events were announced alongside the amendment.

Carolina Rush Corporation (RUSH) is a junior explorer focused on the Brewer Gold-Copper Project in Jefferson, South Carolina. The project is located approximately 13 km from OceanaGold’s producing Haile Gold Mine.

In March 2025, the company released a maiden NI 43-101 Mineral Resource Estimate for the site. The resource includes: - Indicated: 6.2 million tonnes at 0.97 g/t Au and 0.12% Cu (192,000 oz Au, 16.7M lbs Cu). - Inferred: 8.8 million tonnes at 0.74 g/t Au and 0.04% Cu (210,000 oz Au, 8.3M lbs Cu). - Inferred Backfill: 11.9 million tonnes at 0.36 g/t Au and 0.03% Cu (139,000 oz Au, 9.7M lbs Cu).

Historical production at the site totaled approximately 178,000 ounces of gold between 1987 and 1995 via heap leach. The exploration model interprets the deposit as a tilted magmatic-hydrothermal system with a potential deep porphyry copper-gold source.

Recent drilling conducted from January to April 2026 totaled 3,579 meters across three holes. These efforts confirmed an extensive hydrothermal system and porphyry vectors but did not intersect the target porphyry center. Mineralization remains open for expansion.

Additionally, the company has secured 2,524 acres adjacent to Brewer, creating a contiguous 3,480-acre land package for district-scale exploration.
