Carolina Rush-OceanaGold Partnership to Commence Deep Drilling at Brewer in January 2026

Toronto, December 8, 2025 - Carolina Rush Corp. (TSXV: RUSH) (OTCQB: PUCCF) ("Carolina Rush" or the "Company") is pleased to announce that, all required approvals having been received in connection with the Earn-In Option Agreement (the "Agreement") between Carolina Rush and OceanaGold Corp. ("OceanaGold"), all conditions were satisfied and the Agreement became active on November 26, 2025 (see news releases of September 16, 2025 and November 27, 2025 for more information).

The newly formed joint Technical Committee, comprised of two members of each of the companies, has held its first meeting and approved the Stage 1 exploration program and budget, which includes approximately 3,000 meters of drilling beginning January 5, 2026. This Stage 1 exploration program and budget formally commences Phase 1 of the Agreement, during which OceanaGold must spend a minimum of US$1.5 million. To earn a 50% interest in the Brewer Project, OceanaGold must spend a total US$8 million by the end of 2027.

President and CEO of Carolina Rush, Layton Croft, stated: "Our partnership with OceanaGold is off to a great start. Combined technical expertise and knowledge of the large, complex Brewer system helps us de-risk and plan our inaugural deep drill program in alignment together. Our aim is to test Brewer's porphyry copper-gold potential."

Stage 1 Program Overview
The initial deep-drilling campaign will test high-priority porphyry copper-gold targets defined through geologic mapping, geochemistry, and the MT-IP geophysical survey:

• DDH A-1 - approximately 1,500 meters planned: oriented to test the strongest portion of the low-resistivity body interpreted as a potential porphyritic intrusion beneath and west of the former Brewer Mine.
• DDH A-2 - approximately 1,500 meters planned: contingent on A-1 results, this hole will test the southern margin and core of the deep resistivity anomaly, collared in quartz-sericite-pyrite altered volcanic rocks exposed on surface.
• DDH B-1: approximately 1,000 meters planned: designed to evaluate a separate deep MT-IP anomaly to the north-northwest, in an area with anomalous molybdenum, topaz, and trace chalcopyrite-bornite mineralization never previously drill-tested at depth.

These holes collectively aim to determine whether a Cu-Au porphyry system underlies the high-sulfidation epithermal mineralization historically mined at Brewer.

About Carolina Rush
Carolina Rush Corporation (TSXV: RUSH) (OTCQB: PUCCF) is a Southeastern U.S.-focused exploration company advancing the Brewer Gold-Copper Project in South Carolina, which is now under an Earn-In Option Agreement with OceanaGold Corporation. Brewer is a large, underexplored system with demonstrated near-surface Au-Cu epithermal mineralization and potential for deeper porphyry-style mineralization. Brewer is located 13 km from OceanaGold's producing Haile Gold Mine, which has 2025 production guidance of 170,000-200,000 ounces of gold (source: www.oceanagold.com).
