Carolina Rush Partners with OceanaGold on the Brewer Gold-Copper Project

Toronto, Ontario--(Newsfile Corp. - September 16, 2025) - Carolina Rush Corporation (TSXV: RUSH) (OTCQB: PUCCF) ("Carolina Rush" or the "Company") is very pleased to announce it has entered into an Earn-In Option Agreement ("the Agreement") with OceanaGold Corporation (TSX: OGC) (OTCQX: OCANF) ("OceanaGold") on the Company's Brewer Gold-Copper Project in South Carolina, USA. The Agreement grants OceanaGold an option to earn an 80% interest in the Brewer Project and to exercise Carolina Rush's underlying Brewer option (the "Brewer Option") to purchase the Brewer property.

Highlights:

• OceanaGold may earn a 50% interest in the Brewer Project by funding exploration expenditures of US$8,000,000 by December 31, 2027, and an additional 30% interest (for an aggregate 80% interest) by funding an additional US$12,000,000 by December 31, 2030 (see Table 1).
• OceanaGold may exercise Carolina Rush's underlying Brewer Option at any time before it expires on December 31, 2030, including assuming historical environmental liability in accordance with U.S. Environmental Protection Agency (EPA) financial assurance requirements.
• Upon OceanaGold earning a 50% interest, a 50:50 joint venture will be formed with standard rights of first offer and a 2% NSR clause if either party's interest reduces to 10% or less.
• If OceanaGold exercises the underlying Brewer Option before spending an aggregate of US$20,000,000 on Brewer exploration expenditures and earning an 80% interest, Carolina Rush will be carried until that amount has been spent.
• Under the joint venture, Carolina Rush will be the initial operator of the Brewer Project and will receive a 10% unallocated cost allowance.
• The Agreement is conditional on Carolina Rush shareholder approval, to be sought at a Special Shareholder Meeting on October 21, 2025. If shareholder approval is secured, OceanaGold will immediately advance US$150,000 for pre-drilling expenses, and within 12 months of shareholder approval will fund a firm minimum commitment of US$1,500,000.

 *'Commencement' starts upon Carolina Rush shareholder approval

Carolina Rush President and CEO Layton Croft stated: "Our partnership with OceanaGold marks an exciting new chapter in advancing the Brewer Project. OceanaGold is a growing intermediate gold and copper producer with four producing mines around the world, including the Haile Gold Mine located 13 km from Brewer. Their technical expertise and financial support will be instrumental in determining Brewer's porphyry potential by building on our Company's systematic exploration to date. The final step before we start our deep drilling program with OceanaGold is to secure Carolina Rush shareholder approval. To that end our Company's Board of Directors and Management Team strongly encourage all Carolina Rush shareholders to vote 'yes' at our Special Shareholder Meeting on October 21, 2025."
