Exploration History

1950-69 : H.G. Greene; carried out an extensive programme of test pitting (2-4 ft deep) and held 39 claims in 1962.; DD-2-453 ft. 1976 ? : the property was probably acquired from Ruth Greene by Kebrew Holdings Inc. 1973-74 : Globes Minerals Inc. leased the ground and conducted limited auger and diamond drilling. 1975-77 :Goshawk Mines Ltd. (later, 1977, Insulite Development Corp.- auger sampling, diamond drilling and soil sampling and cut a large trench from which 2 bulk samples were taken. These were shipped to Vermiculite of Canada and the Ontario Research Foundation. 1992-1993: A. Archibald: till sampling, drilling, ground geophysics, linecutting, VLF-EM survey 2001-2003; Regis Resources Inc. announced the commencement of production. Adjustments made to plant with upgrading of operation with a large rotary dryer. Additional bulk sampling completed. First full level of commercial production will be reached by March 2004. The plant operated 24 hr/day, 3 days/week and employed a full time staff of 9.

Geology Comments

Dec 07, 2005 (C Papertzian) - Vermiculite occurs in marble, the largest concentrations near surface, near the SW corner of the Anstruther Granite. Flakes are generally < 1/8 inch, but up to 1/2 inch, amber-green-black-silver. Zone A covers an area 457 m (1,500 ft) x 122 m (400 ft) on the E side of the property and is estimated to contain a minimum of 49,400 tonnes of exfoliated vermiculite, averaging 11.9 % . Zone B consists of 4 separate bodies over 2,000 ft and zone C (at the W end) appears to be of fairly good grade.

Lithology

Lithology Comments

Jan 13, 2017 (A Wilson) - "The claim group is mainly underlain by Grenville limestone which has been altered to a marble. Areas can be seen in this marble with disseminated flakes of amber mica which has been altered to vermiculite. In some areas, the vermiculite is heavily concentrated in a mica schist, locally striking approximately east-west. On the south part of the claim group is the Anstruther granite batholith in the form of granite gneiss. Bordering this mass is a band of dark paragneiss which has been altered to biotite schist and amphibolite. In areas of vermiculite-rich limestone, the tops of the ridges generally appear to be capped by harder, vermiculite-poor limestone which has protected the softer vermiculite-rich limestone from erosion. A few localized outcrops show an estimated ten to thirty percent vermiculite. Vermiculite is prevalent in the top soil over large areas and these areas are in many places underlain by vermiculitized limestones". The vermiculite occurs in a band of crystalline limestone that is exposed for about 100 yards on both sides of the road at the point where the road crosses the boundary between lots 13 and 14, con. 2. The limestone band, which is approximately 250 feet wide, strikes northwest and dips steeply southwest. It is flanked on either side by granitic gneisses.

Mineralization Comments

Jan 13, 2017 (A Wilson) - Vermiculite occurs in marble, the largest concentrations near surface, near the SW corner of the Anstruther Granite. Flakes are generally < 1/8 inch, but up to 1/2 inch, amber-green-black-silver. Zone A covers an area 457 m (1,500 ft) x 122 m (400 ft) on the east side of the property and is estimated to contain a minimum of 49,400 tonnes of exfoliated vermiculite, averaging 11.9 % . Zone B consists of 4 separate bodies over 2,000 ft and zone C (at the west end) appears to be of fairly good grade. The vermiculite was found to be too fine for insulation but might be used as an additive in plaster or concrete. Augering and diamond drilling indicated that the largest concentration of vermiculite lies in the free state near surface. Zone A covers an area 457 m long by 122 m wide on the east side of the property. Zone B consists of four separate bodies over a strike length of 610 m. Zone C is located at the west end of the property and appears to be fairly good grade vermiculite.
