CopAur Minerals to Update Current Kinsley Mountain Geology and Mineralization Model

Rhea-AI Summary

CopAur Minerals (COPAF) contracted APEX Geoscience to integrate ~20,000 metres of 2020 and 2023 reverse circulation and diamond drilling into the existing Kinsley Mountain geology and mineralization model.

Kinsley hosts 418,000 indicated ounces at 2.63 g/t Au and 117,000 inferred ounces at 1.51 g/t Au (total 535,000 ounces Indicated & Inferred), including 302,000 oz at 6.11 g/t in the high-grade Western Flank Zone. Selected near-surface oxide intercepts from 2020/23 include 9.83 g/t over 7.6 m and 2.22 g/t over 25.9 m. The modelling will target near-surface oxide exploration zones that could inform future heap-leach recovery and oxide resource expansion.

Pattern Detected

Recent history shows that positive operational and permitting news at Kinsley has sometimes coincided with share price weakness, while financing-related announcements have mostly aligned with subsequent price direction.

Recent Company History

Over the last few months, CopAur focused on advancing its Nevada gold assets and funding that work. On Oct 7, it filed a temporary discharge permit for Kinsley, followed by conference visibility on Oct 22. Financing plans up to $3,000,000 were announced on Oct 23 and closed oversubscribed on Nov 19. On Nov 25, CopAur amended its Williams Property agreement to refocus on Nevada. Today’s Kinsley modeling update continues this Nevada-centric technical and exploration narrative.

Analysis

This announcement highlighted integration of roughly 20,000 metres of drilling into an updated geology and mineralization model for Kinsley Mountain, which hosts reported resources of 535,000 oz indicated and inferred, including 302,000 oz at higher grades in the Western Flank Zone. Investors may focus on how this modeling sharpens near-surface oxide targets, guides future exploration, and connects with earlier permitting and financing activities aimed at advancing Kinsley.

5 terms

reverse circulation technical

"20,000 meters of reverse circulation and diamond core drilling completed in 2020"

Reverse circulation is a drilling method used in mineral exploration where rock fragments are lifted to the surface inside an inner tube while drilling, keeping samples cleaner and faster than conventional techniques. Investors care because it provides quicker, more reliable samples for estimating how much mineral or ore might be present, reduces exploration costs and drilling time, and therefore can speed up or improve the quality of resource assessments that drive project value.

diamond core drilling technical

"20,000 meters of reverse circulation and diamond core drilling completed in 2020"

Diamond core drilling is a method of mining exploration that cuts a cylindrical plug of rock using a diamond-lined drill bit, producing an intact core sample like taking a tissue biopsy from the earth. Investors care because those samples are tested to show the type, concentration and continuity of minerals, which directly affects how much a deposit might be worth, how risky development is, and how confidently companies can plan budgets and timelines.

heap leach technical

"targets that could be considered for potential heap leach recovery in the future"

Heap leach is a mining method where crushed ore is piled into a heap and a liquid is dripped or sprayed over it to dissolve valuable metals, which are then collected from the runoff. Investors care because it is a lower-cost, scalable way to produce metals like gold or copper, but it also affects project timelines, recovery rates, capital needs and environmental or regulatory risk — like choosing a cheap, slow way to extract juice from a fruit versus pressing it quickly.

Vancouver, British Columbia--(Newsfile Corp. - November 27, 2025) - Andrew Neale, CEO of CopAur Minerals Inc. (TSXV: CPAU) (the “Company”) 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 programs 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.
