Other important prospects besides the Temagami Copper Mine, and Kanichee Mine, were being explored on the Mayfair Property. It was at this time when the Mayfair Mining Company had discovered another sulphide occurrence by Vermillion Lake, in the southwest corner of Strathy Township, Nipissing District, Ontario, Canada. The company at the time had additionally staked a total of 23 mining claims on Vermillion Lake. Predictions from the company's geologist soon had stated that the area showed well geological formations for gold, and base metal prospecting. Trebor Mines, Limited, and the Mayfair Mining Company had made partnership deals to further explore this property. Other statements by Trebors Mines, Limited had stated that the company plans to put this area into production.
Further explorations of this area had soon resulted in a wide sulphide zone that had traveled the length of Vermillion Lake. Lower copper, and gold values were strongly reported to have been associated with pyrite, and other statements suggested that copper, and zinc values may be increased by diamond drilling. The area of vermillion lake is considered to have a presence of cross-faulting, and basic intrusive on the property that may have formed this sulphide zone. Some more statements from the company suggested that more diamond drilling needs to be done under the lake as the sulphide zone is said to disappear Explorations of the area revealed that this sulphide zone had a length of 1 mile, and was 30 to 50 feet wide. Much of the whole entire geology of this area is known to consist of minor chalcopyrite, and sphalerite, which are associated with pyritic facies of iron formations.
A geological survey was conducted on the property during the summer, and fall months of 1955. The whole entire survey at this time had mainly been establish by picket lines spaced at 300 foot distances, and marketed by stations at 100 foot intervals. Even more procedures had taken place when the company outlined vermillion, and O'Connor lakes by air photograph.
Much of the whole entire country rock that surrounds Vermillion Lake is known to be in a Keewatin Series, and composed of acid, and basic volcanics striking northeast-southwest, and dipping southeast. These volcanic are strongly determine to form the Keewatin rocks, in which the axis is in the northeast arm of Temagami Lake. Examinations of this area had revealed that the Keewatin rocks are intruded by an older basic intrusive of diorite, gabbro, and paridotite, and the later diabase intrusives of Keewatin Diabase. Additional information reported that some of the basic intrusives are considered to be a sill formation, and other intrusives of Algoma age include granite, and porphyry. . .
