CopAur Minerals Inc. announced that the first diamond drill hole (KMD23-01) is nearing completion. This marks the first milestone in the 3,500 metre (m) combined reverse circulation (RC) and diamond core drilling program presently in progress at the Company's Kinsley Mountain Gold Project (the "Kinsley Mountain Project" or "Kinsley Mountain") in Elko County, Nevada. The Western Flank Zone ("WFZ") resource infill diamond drill hole KMD23-01 has reached a depth of approximately 315 metres of a planned 350 metres hole depth.

From a depth of 250 metres KMD23-01 exhibited elevated arsenic values as determined by semi-quantitative portable X-ray fluorescence (XRF) analysis in association with intervals of oxidation, decalcification, silicification, increased pyrite mineralization within shale beds, faults and breccias, all well- known gold hosts at the Western Flank Zone. The Kinsley Mountain drill program will include up to 2,300 metres of RC and 1,200 m of diamond drilling. objectives of the 2023 Kinsley Mountain Drill Program: Western Flank Zone resource infill core drilling proximal to historical core drill holes yielding 21.3 grams-per-tonne (g/t) gold (Au) over 29 metres within hole PK137C2.

Test Kinsley Ridge induced polarization (IP) geophysical target to Secret Canyon Shale depth within an undrilled area between WFZ and the past producing Ridge Pit. The Kinsley Ridge target was based on 100 line-km of IP/resistivity surveys completed by the Company during 2021 and 2022 that generated numerous untested changeability anomalies. Main Pit North RC drilling to test the Company's 2020 shallow oxide gold intercept of 9.83 g/t gold over 7.6 metres in KMR20-0302.

High-grade oxide gold mineralization intersected to date at Main Pit North occurs within 120 metre depth from surface and 75 metres outside the current resource pit shell representing a unique resource expansion opportunity. Secret Spot.
