The Straight-Across occurrence is located on a ridge 1.5 kilometres southeast of the outlet of Glacial Lake, about 39 kilometres southeast of the town of Dease Lake and 25 kilometres due east of Highway 37. It is approximately 900 metres north of the Wolf (104I 056) copper showing.

The showing displays similar argillic to advanced argillic alteration as Tanzilla (104I 050), Gopher zone, Mo East (104I 146) and Straight-Up (104I 172) showings located 10 kilometres west-northwest. Leached cavities are common, except in rare areas where abundant (less than 5 to 10 per cent) disseminated pyrite is preserved. A sample did not return significant base or precious metal concentrations. Massive grey silica plus/minus sericite altered volcanics are likely the Upper Triassic-Lower Jurassic Horn Mountain Formation (Hazelton Group). The southern part of the occurrence, and an isolated outcrop 300 metres to the east, consist of biotite hornfelsed and locally quartz-pyrite altered augite-bearing plagioclase porphyry, similar to the syn-mineral porphyry at Tanzilla. The area surrounding the Straight-across occurrence is covered by thick overburden.
