Jul 28, 2017 (A Wilson) - Steeply dipping Keewatin pillowed andesite that strikes NW and faces NE occurs intruded by irregular mafic intrusives less than 20 ft. thick and dipping less than 30ºW. Haileyburian biotite and hornblende lamprophyre dikes also cut the Keewatin andesite. Nipissing diabase as part of the south dipping north limb of the New Lake Diabase basin occurs below the Keewatin andesite from 0 to 600 ft. below surface. Small fractures contain epidote, calcite, red feldspar and minor sulphides.

Aug 08, 2017 (A Wilson) - No silver or cobalt production has been obtained from the property to-date. The late D, J. Russell, at one time manager of Oxford Cobalt Silver Mines Limited, showed the writer a silver ingot with volume of about one cubic inch, and stated that this had been produced in the assay office from Oxford shaft No, 3 vein. Economic interest in the property is predominantly for silver but there is a galena occurrence at the Cummings pits in the southeast corner of claim T 19492 which at one time was regarded as a possible source of lead.
