"importantly, this project is 100% owned by guardian metal, royalty free. conveniently, it is also 15 km away from pilot mountain and shares the same access road. "we look forward to continuing to move this opportunity forward rapidly, alongside the important work that is currently ongoing at both pilot mountain and tempiute."   technical summary § pilot north includes the historical world war ii-era mines of "copper head", "western metals", "muller mountain", "jasper" and "tungsten valley", each with extensive outcropping tungsten (w) - copper (cu) bearing skarns at the contact of granitic intrusions with limestones of the luning formation (i.e. the same geology as the company's pilot mountain project).   § notably, very high-grade copper, silver, tungsten, zinc and strongly anomalous lead, gallium and gold was returned from multiple areas within the project including (table 1):   o 31 overlimit copper assay results including: 14.65%, 10.6%, 9.21%, 8.86%, 7.22%, 6.92%, 6.89%, 6.78%, 6.7%, 6.27%, 5.56% and 5.3% cu.   o 12 overlimit silver assay results including: 708 g/t, 538 g/t, 496 g/t, 319 g/t, 284 g/t, and 276 g/t ag.   o 13 overlimit tungsten trioxide (wo3) assay results including: 0.59%, 0.46%, 0.40%, 0.36%, and 0.36% wo3.   o additionally, gold results up to 1.025 ppm au, gallium results up to 49 ppm ga, zinc results up to 12% zn, and lead results up 3.81% pb.   § the company shortly will be undertaking detailed geological mapping of the most prospective areas to guide the next exploration steps which may include geophysical surveys and diamond drilling.   background pilot north is located approximately 15 km northwest of the company's co-flagship pilot mountain project and shares the same road access. pilot north comprises five distinct areas: copper head, western metals, muller mountain, tungsten valley and jasper. the company considers that these all represent genetically related tungsten-copper-polymetallic skarn mineralisation at the contacts of granitic intrusions with limestones of the luning formation, a similar geological setting to the deposits at pilot mountain. following initial reconnaissance and staking of pilot north, the company's expert geological consultant, dr lawrence carter, undertook detailed geological mapping and sampling across the project to characterise the mineralisation and to develop strategies to advance pilot north as a satellite to the company's flagship pilot mountain project. from this fieldwork, 92 rock chip sampled were assayed at als usa inc laboratories using the following analytical packages: me-ms61 for multielement, au-icp21 for gold, me-xrf15c for high grade wo3 and  ag/cu/pb/zn-og62 for overlimit samples (see table
