The SK-7 region is underlain by massive plagioclase porphyritic basalt flows and coarse-bladed plagioclase and pyroxene porphyry dikes of the Upper Triassic Stuhini Group, Mess Lake Volcanic Facies. Middle to Late Triassic medium-grained equigranular augite diorite and gabbro of the Stikine Plutonic Suite are in contact with the Stuhini rocks just north of Skeeter Lake. Biotite granite to tonalite of the Late Devonian Forrest Kerr Plutonic Suite are in fault contact on the 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-7 intersected basaltic augite porphyry with up to 2.5 per cent primary magnetite and a trace of pyrite. Trace amounts of bornite occurred over a 6.1 metre interval. The IP anomaly was thought to have been due to magnetite content.
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.
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 claims. Also see BB 57 (104G 118) for related details.
