Aug 14, 2017 (A Wilson) - Keewatin bedded cherty sediments as well as softer varieties are exposed in the vicinity of New Lake Creek. The rocks in the vicinity of the creek are fractured. Apparently the surfaces along which movement has taken place are distributed over a width of from 100 to 200 ft. The rock at the bottom of the shaft is said to be greatly broken and intersected by mud seams.

Aug 14, 2017 (A Wilson) - Pyrite, galena and sphalerite are disseminated, in small amounts, so far as seen in them. Mr. O. Gauthier reported that one band of pyrite exposed in the shaft was 2 feet wide. Cobalt bloom was not seen by the writer in the shaft dump but Mr. Gauthier reported a one-inch cobalt-bearing vein had been disclosed by the shaft. S. Cole reported that 6 samples taken from the shaft carried between 4 and 23 ozs. silver per ton and that samples containing galena and pyrite from the dump yielded assay returns of about 100 ozs. silver per ton. Shaft samples assayed up to 3900 g/t Ag; pyrite-galena up to 3400 g/t Ag.
