The SK-3 region is underlain by mafic to intermediate lapilli tuff, lesser ash, breccia and tuffite: aphyric or plagioclase and augite-phyric and coarse-bladed plagioclase porphyry flows and sills of the Upper Triassic Stuhini Group, Middle to Late Triassic medium-grained equigranular augite diorite and gabbro of the Stikine Plutonic Suite are in contact with the Stuhini rocks north of Skeeter Lake. Biotite granite to tonalite of the Late Devonian Forrest Kerr Plutonic Suite and Pennsylvanian carbonate rock of the Stikine Assemblage are in fault contact with the Stuhini rock to the immediate east.
In 1981, Teck drilled 7 holes (SK-1 to SK-7) along a north-south access road over 5 kilometres. All drill holes were reported to have cored andesitic fragmental rocks, pyroclastics, tuffs and flows. Drill hole SK-3 was drilled on metal factor and frequency effect anomalies. Andesitic flows and pyritic and graphitic tuffs were encountered with trace to 0.3 per cent chalcopyrite (Assessment Report 10067). The IP anomaly was explained by pyrite and graphite.
Work History
During 1971 Hecla Operating Company performed a soil geochemical survey for copper, a ground magnetometer survey, and geological mapping of the Skeeter Lake valley. A few minor chalcopyrite showings were located, and several small weakly anomalous soil areas outlined. The magnetometer survey helped correlation of geology.
In 1973 Hecla surveyed four reconnaissance induced polarization lines on the claim group. Possible anomalous results were obtained on all four lines, but the lines were too widely spaced for correlation.
In 1981 Teck Explorations Limited contracted Phoenix Geophysics Ltd. to survey 15.6-line kilometres of induced polarization on lines spaced 300 metres apart. Several anomalous zones were identified and were tested by drilling of seven 122-metre-deep diamond-drill holes. These holes, designated SK-1 to SK-7 were drilled from south to north over 5 kilometres along a rough access road or trail, immediately west of Skeeter Lake.
In 2015, Teck Resources reported mineralization north of Skeeter Lake. See Schaft Creek (104G 015) for further details of work done by Teck Resource in the area of the Schaft Creek deposit.
