The Matt occurrence is located about 85 kilometres east-southeast of the community of Dease Lake, approximately 7.8 kilometres west of the Kutcho Creek airstrip. The showing was discovered during the 2011 mapping program by the British Columbia Geological Survey.

The Matt showing comprises a narrow, mineralized layer within Mississippian to Triassic Cache Creek Complex metasedimentary rocks located 1 kilometre north of the Nahlin fault. The mineralized unit is a layer of dark grey phyllite, 8 centimetres wide, which is stained with malachite and includes numerous small pits that may represent weathered-out sulphides. The host succession comprises siliceous phyllite, chert and cherty argillite, with local lenses of talc schist. A grab sample of malachite-stained rock from the pitted phyllite unit contains 4468.9 parts per million copper, 33.3 parts per million molybdenum, 29.1 parts per million lead and 2335 parts per million barium (Table 1, sample11PSC-410; Fieldwork 2011, page 96).
