Property Visits
Company Property Township or Area Commodity Comments
Canadian Wollastonite St Lawrence Wollastonite Deposit Leeds Wollastonite Site tour for RGP staff to see the latest mine development, products, and environmental mitigation work. The tour was part of an RGP-wide section meeting.
HAK Resources Development Corp Easton Quarry Griffith Marble (Building Stone) Site visited by RG and SGA with claim holder who had recently acquired the claims. The visit was to assess the property, quarry, and stockpile. The road in to the site is very overgrown and narrow. The site itself is very overgrown with only parts of a large stockpile of marble boulders visible.
HAK Resources Development Corp Griffith Marble Prospect Griffith Marble (High Purity/Flux) Site visited by RG and SGA with claim holder to view the progress of clearing overgrowth and outcrop exposure and cleaning. The work is in preparation for a bulk sampling project.
J Clements Hardie Property Barrie Gold, Silver, Zinc Site visit by DG and RG with prospectors to view their newly acquired property. J Clements has recut trails and improved access to the site. Trenches and pits were located and samples were collected. The North and South zones within the Flinton Group's Myers Cave and Bishops Corners formation were identified.
J Merow Old Stoklosar Quarry Madoc Marble (Building Stone) Site visit by RG, RLUG and M. Forget to view stromatolite occurrences in outcrops and waste rocks.
Municipality of Highlands East Harcourt Graphite Mine Cardiff Graphite, Mineral Specimen The Harcourt Graphite Mine's adit and pit were visited by the Southern Ontario District Geologist and summer student. Coarse-grained flake graphite, up to 2-3cm across was abundant. One composite sample from the weathered exposed outcrop was collected. The visit was limited by inclement weather.
S Wanning Wanner Property Elzevir Copper, Gold, Silver Property tour for RGP staff. Examined access, 3 old pits and waste piles.

Hwy 41 near Shirtcliffe Lake Kaladar Sillimanite, Zinc Visited by the SO DG. Roadcuts north and south of the powerline were examined. North of the power line, a vein with a pinkish red alteration (cobalt bloom or rhodochrosite?) was sampled. The Shirtcliffe zinc discretionary occurrence (MDI31C11SE00119) could not be located under the powerlines and have been recommended to be deleted. South of the powerlines, the Shirtcliffe Lake sillimanite occurrence was examined as well.
Dubblestein Industrial Minerals Property Lyndoch Dolomite (Flux/Filler), Graphite, Magnesium Minerals, Silica RGP staff received a tour of the property from prospector M. Forget. Access was examined as well as high-purity dolomite and silica zones. Samples of both were collected.
Herring Lake Marble Sheffield Marble (Building Stone), Silver The location of sample HL001 (from assessment file 20000007897) was visited for further examination, as silver results of 56.1 g/t for HL001 are found in the assessment file, but are are unremarked upon. The original location of the sample was easily located, as small blocks had been removed by rock saw. This area was resampled, as well as an interesting vein visible in the roadcut.
Craig Gold Tudor Gold Historic workings (trenches, 2 shafts, and large dump piles) of the past-producing Craig gold mine were examined. Site features were located with LiDAR and cross-referenced with historical data.
