The Kutcho 1 occurrence is located just to the west of Kutcho Creek, a little more than 4 kilometres south of the airstrip, about 93 kilometres east-southeast of the community of Dease Lake.

The Kutcho 1 showing is hosted by the central division of the upper Permian-Lower Triassic Kutcho assemblage. Mineralization comprises lenses of semi-massive to massive sulphide within a pyritic cherty exhalite unit, which is intermittently exposed in an area measuring about 80 by 40 metres (Assessment Report 24866). Mineralization in the vicinity of the Kutcho 1 occurrence was encountered in a diamond-drill hole cored by Noranda Exploration Company, Limited in 1977. Chloritic schist intersected in hole NK-3 included a 3-metre interval containing 2 to 5 per cent pyrite with disseminated chalcopyrite, which contained 0.11 per cent copper (Assessment Report 6686). The area was re-staked and mapped in 1994 and optioned to Atna Resources Limited in 1996. The area was mapped as a pyritic cherty exhalite unit in 1994, and during follow-up work for Atna Resources in 1996 a pit was excavated where an angular float block of massive to semi-massive pyrite-chalcopyrite was discovered within the unit. This pit exposed bedrock of highly siliceous rock with about 20 per cent pyrite that locally displays primary sulphide layering. A sample of this bedrock material yielded 3282 parts per million copper, 1110 parts per million lead, 1097 parts per million zinc, 7.0 parts per million silver and 7 parts per billion (ppb) gold (Assessment Report 24866). Several mineralized float boulders were encountered during excavation of the pit, including a 5 kilogram subangular block of well banded, siliceous, semi-massive to massive sulphide, which contained 10,592 parts per million copper, 2234 parts per million lead, 1816 parts per million zinc,17.6 parts per million silver and 30 parts per billion gold (Assessment Report 24866). An exploration program by Atna Resources Limited in 1997 included 9 diamond-drill holes, several of which were cored in the area of the Kutcho 1 showing (Assessment Report 25465). However, none of these holes were filed for assessment.

The pit excavated within the pyritic cherty exhalite unit was located during a 2011 mapping program by the British Columbia Geological Survey, but it is partially caved and bedrock is no longer exposed. The cherty exhalite exposed near the pit is a light to medium grey, very siliceous rock with several per cent disseminated pyrite, and local lenses and patches of heavily disseminated to semi-massive pyrite. Rocks to the east and northeast of the exhalite unit are mainly epidote-chlorite schists derived from mafic volcanic rocks. Rocks to the south and southeast include coherent units of quartz-plagioclase-phyric metarhyolite intercalated with pyritic siliceous exhalite similar to that near the pit, and two narrow units of mottled red/grey chert that are probably also exhalites (iron chert units from Assessment Report 24866). These iron chert units commonly have 1 to 2 per cent disseminated pyrite, and local narrow lenses of more heavily disseminated pyrite. A sample collected from one of the iron chert units, located 80 metres southeast of the pit, contains 652.5 parts per million copper, 33.3 parts per million lead, 669 parts per million zinc and 1.2 parts per million silver (Table 1, sample 11PSC-438; Fieldwork 2011, page 94).
