Carolina Rush completes initial Brewer Porphyry drill program

Toronto, Ontario--(Newsfile Corp. - July 13, 2026) - Carolina Rush Corporation  (TSXV: RUSH) (OTCQB: PUCCF)  ("Carolina Rush" or the "Company") reports results from Hole B26C-039 ("Hole 39"), the third and final hole of the initial deep drill program at the Brewer Gold-Copper Project in South Carolina, USA, funded under the Company's earn-in agreement with OceanaGold Corporation (TSX: OGC) (NYSE: OGC) ("OceanaGold"). Hole 39 was drilled approximately 400 meters southeast of Hole 37 and collared just west of the former Brewer mine, intersecting significant gold-copper mineralization and demonstrating lateral continuity of the Brewer epithermal system in a previously untested area. Hole 39 completes the initial three-hole deep porphyry exploration drilling campaign at Brewer.

In conjunction with Holes 37 and 38, results from Hole 39 support the geologic model of a shallow northwest dipping alteration system and strengthens the Company's interpretation that the core of the copper-gold porphyry system is located further west-northwest and remains untested by drilling. Highlights 51 meters grading 0.62 g/t gold ("Au") and 0.22% copper ("Cu") from 214.0 meters, including: 12 meters grading 1.04 g/t Au and 0.60% Cu from 217.5 meters; Au-Cu mineralization encountered in Hole 39 represents a 50-meter step out from the nearest intercept used to calculate the current Mineral Resource Estimate; Mineralization remains open for expansion and demonstrates continuity of the broader Brewer hydrothermal system; The result highlights potential opportunities for future resource growth while complementing the Company's ongoing evaluation of deeper exploration targets. Carolina Rush CEO, Layton Croft, stated: "Hole 39 demonstrates that Brewer continues to offer opportunities for value creation.
