Access Description: Highway 11/17 east to the Dorion Mine Road. Head south for 1.6 km., just before the second gravel pit turn east onto a bush road. Follow this road for 1 km. to the railway track. Follow the path for 600m to the west end of the occurrence.
1940s: area was prospected for base metal mineralization. Old workings consist of several trenches and the adit. 1967: Mr. Dzuba acquired the mineral rights and proceeded to work the claim for amethyst. 1970: stripping and shallow trenching. 1972: Dzuba carried out manual trenching. 1974: Dzuba dug trenches. 1976: Dzuba carried out blasting and trenching. 1977: Dzuba carried out power stripping. 1979: Dzuba carried out stripping, trenching, and blasting. Production continued for approximately 15 years, until about 1982. 1982: Noranda Exploration Company Ltd. carried out linecutting, geological mapping, rock and soil sampling, and mag and EM geophysical surveys. 1986: property was staked by J.W. Redden. 1988: J.W. Redden carried out stripping and a VLF-EM survey. 2014: D. Kalik and J. Harasym carried out stripping and trenching.

Jun 01, 2018 (Therese Pettigrew) - The main part of the occurrence is in a wide carbonate-quartz breccia zone which has been traced along strke for 600 m at an azimuth of approximately 090 degrees. The breccia separates Archean monzonite to the north from Sibley Group mudstone to the south. The monzonite is dark pink and massive, the mudstone is red, fine grained, thinly bedded, with small grey reduction spots.

Jun 01, 2018 (Therese Pettigrew) - Silicification of the mudstone is evident close to the breccia zone. The breccia zone varies from 1.5 to 4. M wide and consists of angular clasts of monzonite and mudstone in a matrix of quartz, calcite, and some barite. Sulphides, chalcopyrite, galena, and sphalerite occur in disseminations and veinlets towards the northeastern end of the breccia. Amethyst occurs in the quartz-carbonate matrix and as spectacular points lining some very large vugs in the vein. The colour of the amethyst is quite variable, from almost pink to very dark purple (Garland, 2000).
