Expansion Of Troy Canyon Mineralized Trend

VANCOUVER – CopAur Minerals Inc. reported on the final assay results from the 2025 field-based program of geologic mapping and surface rock geochemical sampling at the Troy Canyon property in Nevada. The Troy Canyon gold-silver project is in the Grant Range of eastern Nye County, NV, approximately 150 km 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 along the contact between the limestone hanging wall and the quartz monzonite footwall of the Tertiary (23 Ma) Troy pluton.
The 2025 Troy Canyon rock sampling program included the collection of 56 samples from outcrop and historic mine workings. Of the 56 samples, a total of 9 samples returned greater than 0.1 grams-per-tonne (g/t) gold (Au) and up to 23.1 g/t Au. A total of 7 samples returned greater than 10 g/t silver (Ag) and up to 56 g/t Ag.
Highlights of 2025 rock sampling at Troy Canyon include: 1) 23.1 g/t Au and 11.1 g/t Au; including 25 g/t Ag and 37 g/t Ag, respectively from historic mine workings outcrops located 300 metres west of the historic Locke Gold Mine portal at the West Locke workings. 2) 56 g/t Ag, 48 g/t Ag and 36 g/t Ag from the Sheepherders adit located 80 metres north of the Locke Mine portal; and from the West Locke workings. 3) New discovery of mineralized quartz-hematite breccia zone returning 31 g/t Ag located 1,000 metres southwest of the Locke Mine.
Mineralization at Troy Canyon occurs within quartz vein and hematite-breccia bodies localized along the sheared contact of the Troy pluton. All mineralized samples occur within this silica body in localized zones with silica-hematite veining, stockwork, and breccias. Bedding measurement and the presence of Z-folds suggest the main zone silica body lies on the limb of an anticline located to the southwest that was not encountered during mapping. The strike of the veins and breccias is similar to bedding measurements in the limestone, although they are steeper and dip to the west, an observation that will enhance future drill targeting. Mapping and prospecting have also resulted in the expansion of the Troy mineralized trend from 400 to greater than 1,000 metres with the discovery of mineralized quartz-hematite breccia along strike to the southwest.
