History and Exploration:
1957 – Jonsmith Minex, Limited.
Jonsmith Mines had acquired a total of 45 claims in Sewell Township, in which a group of 13 claims were examined. These foremost claims had extended south from Weston Lake to Crossover Lake and were surveyed in 1956. Surveying during this period was done by using ground magnetic and electromagnetic methods. A north-south trending magnetic anomaly, that’s about 1,200 feet long and 400 feet wide, was outline between Highway 101 and the southern corner of Weston Lake in an area underlain by migmatite composed of hybrid diorite and xenolithic granodiorite containing large blocks of amphibolite, mafic pillowed volcanic flows, and quartzo-feldspathic gneiss. Some of these large blocks also contain appreciable disseminated pyrite, and pyrrhotite in place. Upon examination a total of seven surface diamond drill holes were drilled on this anomaly in the spring of 1957, which totalled 1,891 feet in length. Drilling had indicated that the main part of the magnetic anomaly is due to an unexposed diabase dike. A small but more intense magnetic peak on the southwestern side of the main anomaly appears to be due to a large block or blocks of amphibolite included in the granodiorite and containing sparsely disseminated pyrite and pyrrhotite and very rare chalcopyrite.
1957 - Canadian Johns Manville Company Limited.
Canadian Johns Manville had acquired a group of seven claims to its asset in the northern part of Weston Lake. Upon examination it was revealed that the area is covered by sandy overburden and there are no exposures. The area was mapped in 1957, which revealed that the underlying rocks are believed to be migmatitic and hybrid granodiorite. This resulted in dropping the claims in Sewell Township.
1957 – 1965 – Canadian John Manville Company, Limited.
This also resulted in staking out claims on the northern part of Weston Lake that comprised of 14 claims. Geological and geophysical surveys were carried out in the area, but revealed no surface exposures. These claims were shortly after dropped before another group of claims were acquired in 1965. It was during this time period that two holes were diamond drill on unpatented claim S124757. One of these holes was stopped at 112 feet in overburden, and the second hole cut 102 feet of overburden and then continued to 650 feet essential lying in granodiorite.
1964 – L. Lapierre
A large area between Weston Lake, Crossover Lake, and Sewell Lake was staked by L. Lapierre in 1964. Mr. L. Lapierre had also owned a saw mill on Weston Lake which is now referred as Old Mill Camp. This resulted in diamond drilling four surface holes, totalling 1,255 feet in length. Three of these holes are located to the south of Crossover Lake, and the fourth is about 500 feet east of Sewell Lake outlet bay. All four of these holes had intersected mainly light coloured mafic metavolcanics and minor felsitic and rhyolitic material. Small quartz veins and stringers are present in all the holes, and minor pyrite, with traces of chalcopyrite, is reported in the drill hole east of Sewell Lake in the northern hole of the group located south of crossover Lake.
