CopAur Minerals to Update Current Kinsley Mountain Geology and

Mineralization Model

Vancouver, British Columbia — November 27th, 2025 — Andrew Neale, CEO of CopAur Minerals Inc. (the

“Company”) (CPAU:TSXV) is pleased to report that the Company has contracted APEX Geoscience Ltd. of

Edmonton, AB to begin work to integrate the results of approximately 20,000 meters of reverse

circulation and diamond core drilling completed in 2020 and 2023 into the existing Kinsley Mountain

geology and mineralization model. Kinsley hosts current mineral resources of 418,000 indicated ounces

at 2.63 g/t gold and 117,000 inferred ounces at 1.51 g/t gold, (a total of 535,000 ounces Indicated &

Inferred) which include 302,000 ounces averaging 6.11 g/t gold within the high -grade Western Flank

Zone1.

“These drill program s were primarily an expansive exploration and near resource focused effort that

looked to equally make (i) new discoveries and (ii) target near resource expansion around the Main Pit.

This modeling effort will further delineate near surface oxide exploration targets that could be considered

for potential heap leach recovery in the future and provide the Company with further direction for

continued oxide resource expansion exploration efforts,” commented Andrew Neale.

Near surface oxide intercepts from the 2020/23 drill programs, as previously reported, include2:

• 9.83 g/t gold over 7.6 metres within a broader zone grading 2.88 g/t Au over 36.6 metres in

KMR20-030 at Mine Pit North located 75 metres north of the existing resource pit shell.

• 2.22 g/t Au over 25.9 metres; including 4.2 g/t Au over 10.7 metres in KMR23-03 at Main Pit

North outside the resource pit shell.

• 1.77 g/t gold over 25.3 metres in KMD20-07B, a new surface oxide discovery at Secret Spot.

Kinsley was last in production in 1998, when gold prices averaged around US$360 per ounce. Alta Gold

suspended operations to pursue another project and later entered bankruptcy, leaving Kinsley idle despite

its strong exploration and development potential.
