Point Location Description: DDH 13 report 31D09NW0013
Location Method: Data Compilation
Access Description: Trenches excavated in the angle formed by Hwy 507 and the old road route in the extreme NW corner of lot 14, con 2. Access is by paved Highway # 507 (open year-round) which cuts through the eastern section of this claim group. This highway can be accessed from Gooderham in the north and from a highway which joins Lindsay/Bobcaygeon to Peterborough in the south. The property is bordered immediately to the east by Mississagua Lake.
1962: Zone D of Greene Deposit ( showings of vermiculite in SE corner of Cavendish Township. Trenches show 10-15 % mica or are barren.1992- 1994: A. Archibald – Cavendish Vermiculite Deposit; till sampling, overburden drilling, geochemical, geophysics.

Jan 16, 2017 (A Wilson) - The claim group is mainly underlain by Grenville limestone which has been altered to marble, dolomite, and diopside. Areas can be seen in this marble with disseminated flakes of amber mica (Phlogopite and biotite) which has been altered to vermiculite. The higher grade vermiculite flakes are of a green colour. In some areas, the mica is heavily concentrated in a mica schist, or an amphibolite schist unit. These units locally strike east-west in the area between Catchacoma and Mississagua Lakes, and northeast-southwest in the areas to the west around highway #507.

Jan 16, 2017 (A Wilson) - Vermiculite is prevalent in the top soil over large areas and these areas are in many places underlain by vermiculrtized limestones. Amber, green-black, and silver mica when exfoliated becomes a light cream colour. Flakes of mica to one-quarter inch are uncommon with the main flake size under one-eighth of an inch. Some of the mica is only partially vermiculitized and will not fully exfoliate. As vermiculite is light and tends to float , a secondary concentration of this material should be found in low or swampy areas. There are several swampy areas or low-ground conditions underlying the claim group and survey area near known vermiculite-rich sections which may have concentrations of vermiculite. These areas could be of economic interest. No attempt has been made to explore the bedrock but some road-cuts along highway # 507 have shown the vermiculite to be exposed in lenses or shear-controlled fractures
