COPAUR COMMENCES GEOLOGIC MAPPING AND ROCK GEOCHEMICAL FIELD PROGRAM AT TROY CANYON

Copaur Minerals Inc. has engaged Apex Geoscience Ltd. of Edmonton, Alta., to complete a field-based program of geologic mapping and surface rock geochemical sampling at the 100-per-cent-owned Troy Canyon property in Nevada.

The Troy Canyon gold-silver project is in the Grant range of eastern Nye county, Nevada, approximately 150 kilometres east of Tonopah. The project consists of 59 contiguous unpatented mineral claims covering 493 hectares. High-grade gold mineralization occurs within massive quartz veins, vein breccias, and narrower sheeted vein and stockwork zones exposed for over 300 metres along the contact between the limestone hangingwall and the quartz monzonite footwall of the Tertiary (23 million years) Troy pluton.

The fall 2025 Troy Canyon exploration program is designed to follow up on high-grade gold-silver assays returned during the company's prior sampling efforts. The new surface rock samples will be augmented by detailed geologic mapping designed to advance the understanding of the structural and geologic controls on mineralization preparatory to diamond drill hole planning.

Field crews are currently on the site at Troy Canyon, and initial geologic observations indicate mineralized quartz vein and breccia localization preferentially along the intensely sheared contact of the Troy pluton and down plunge continuity possibly related to fold axis within the overlying Cambrian limestone and shale units.

Highlights of Copaur prior rock sampling at Troy Canyon include:

• 42.7 grams per tonne gold, 15 g/t Au and 91 g/t silver in outcrop of partially oxidized silica-sulphide breccia at the historic Locke West and East mine prospects;
• 37.7 g/t Au in oxidized quartz vein material sampled from historic waste dumps at the Locke East mine;
• 7.68 g/t Au, including 526 g/t Ag, in addition to 97.20 g/t Ag and 105 g/t Ag, from mine dump material coincident with 1.2 kilometres north-south trending greater than 10 parts per billion Au in soil anomaly along the western Troy Canyon claims along the historic Leadhill and Galena vein trends.

"The Troy Canyon property encompasses the past-producing Locke mine, which operated in the late 1940s, processing ore on a small scale, with gold grades reportedly in excess of 10 grams per tonne. This field reconnaissance is designed to support a permitting program in 2026 that will allow the company to initiate a diamond core drill program in late 2026 or early 2027," commented Andrew Neale.
