Tertiary Minerals plc announced that it has staked claims over a new copper exploration project at Brunton Pass in Nevada, USA. The Company has staked 24 new mining claims on the east side of the Paradise Range, just north of State Highway 91, 190 km southwest of Reno, Nevada. Mercury was discovered in the claim area in 1945 and a small amount of mercury was produced in 1948. The area south of the mercury workings was drilled by Phillips Uranium Corp. in 1978 to test a reportedly large scintillometer anomaly but no further records can be found. The prospect area is underlain by Triassic-age limestone, sandstone, and siltstone which has been intruded by diorite. The sedimentary rocks are strongly altered locally and appear to be in fault contact with Tertiary-age volcanic rock (rhyolite) on all sides. Prospector small-scale workings are spread throughout a 1km x 0.6km area within the sedimentary enclave. Most of the workings explore shear zones and contact metasomatic (skarn) zones containing garnet, epidote, calcite, and copper minerals. Zones of silicification are abundant. The Company's copper-rich samples are also anomalous in uranium (up to 106ppm) and so the report of a large scintillometer further enhances the prospectivity of the project. The Company has commissioned a detailed drone magnetic survey to assist in target delineation. This will be carried out within the next two weeks and further exploration will follow.
