Carolina Rush expands Jefferson Project near Brewer

Toronto, Ontario--(Newsfile Corp. - August 11, 2026) - Carolina Rush Corporation (TSXV: RUSH) (OTCQB: PUCCF) (the "Company") has executed nine new mineral lease agreements for 2,524 acres adjacent to the west and northwest of the Brewer Gold-Copper Project in Chesterfield County, South Carolina. Since 2016, the Company has leased land outside the Brewer property, referred to as the Jefferson Project, which is 100%-owned by Carolina Rush. Together, the Brewer Project and the Jefferson Project now constitute a 3,480-acre contiguous land package (see Figure 1).

Highlights

Nine new mineral leases for a total of 2,524 acres have been secured to expand the 100%-owned Jefferson Project adjacent to the west and northwest of the Brewer property;

The Jefferson and Brewer projects now form a contiguous land package covering 3,480 acres;

Eight of the nine new Jefferson Project leases require no annual lease payments for the first 10 years;

Recent drill results and independent geological review reinforce the importance of evaluating the Brewer gold-copper system further northwest and down-dip; and

The expanded land position provides room to assess deeper porphyry copper-gold targets and additional near-surface epithermal gold targets.

Carolina Rush President and CEO Layton Croft stated: "Recent drilling at Brewer materially improved our understanding of the gold-copper system and reinforced the importance of western-northwestern targeting. Securing 2,500 additional acres gives Carolina Rush a much larger land position while preserving capital for exploration. More than 90% of Jefferson Project land has no annual lease-fee requirement for the next decade. We believe this is a disciplined expansion that strengthens the Company's long-term exposure to both porphyry copper-gold and epithermal gold opportunities across the greater Brewer district."

About the Jefferson Project Carolina Rush has maintained its 100%-owned Jefferson Project since 2016 through private mineral leases outside the Brewer property, most recently until now including one lease covering 44 acres. The Company's ten new leases are now effective with multiple arm's-length private landowners and no material closing conditions outstanding. No securities were issued and no finder fees were paid in connection with any of the Jefferson Project leases. The Jefferson Project today includes ten active mineral leases covering 2,568 acres adjacent to the west and northwest of the Brewer property.

All ten Jefferson Project agreements provide Carolina Rush with exclusive mineral exploration and property purchase rights, subject to their respective terms. In all cases, the property purchase price excludes consideration of any mineral resource potential. Eight of the ten leases have no annual lease payments during the first 10 years and include a future production royalty. Two lease agreements have annual lease payments and no royalty.

The expanded Jefferson land position allows the Company to incorporate a substantially larger area into its district-scale geological interpretation and assess prospective areas for porphyry copper-gold and near surface epithermal gold targets. There has not yet been sufficient exploration to determine whether mineralization identified at Brewer extends onto Jefferson.

About the Brewer Gold-Copper Project The Brewer Gold-Copper Project consists of two land parcels for a total of 912 acres, located in Chesterfield County, South Carolina. Brewer was historically operated as an open-pit oxide gold mine. It produced approximately 178,000 ounces of gold before mining ended in the mid-1990s. Carolina Rush's exploration since 2020 has identified a large and complex magmatic-hydrothermal system below and around the former mine. The Brewer Project contains near-surface gold-copper mineralization and deeper porphyry-style exploration potential.

The Company recently completed an initial three-hole deep drilling program at Brewer. For drill results and analysis see the Company's news releases of May 4, 2026 , June 25, 2026 , and July 13, 2026 .

The Company's 2025 Brewer maiden Mineral Resource Estimate includes:

An Indicated mineral resource of 6.2 million tonnes grading 0.97 g/t gold and 0.12% copper, containing 192,000 ounces of gold, together with 16.7 million pounds of copper;

An Inferred mineral resource of 8.8 million tonnes grading 0.74 g/t gold and 0.04% copper, containing 210,000 ounces of gold and 8.3 million pounds of copper; and

An additional Inferred backfill mineral resource of 11. 9 million tonnes grading 0.36 g/t gold and 0.03% copper, containing 139,000 ounces of gold and 9.7 million pounds of copper.

The Mineral Resource Estimate is supported by a Technical Report entitled "NI 43-101 Technical Report and Mineral Resource Estimate - Brewer Project", with an effective date of March 20, 2025. The report is filed on SEDAR+ ( www.sedarplus.ca ) and available on the Company's website .
