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:
 
 
 Table 1: Principal Structure of the AgreementOceanaGold  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.

 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."
