The Belleterre property is located 120 km south of the city of Rouyn-Noranda and 3 km north-west of the town of Belleterre, in the Temiscamingue region of Quebec, Canada. The property is consists of 155 claims totaling an area of 24.8 km2. The former Belleterre mine is located 5 km to the west (production of 960 000 ounces of gold at 10.70 g/t Au between 1936 and 1959).
The Belleterre region straddles the limit between the Superior and Grenville provinces and is characterized by the Belleterre greenstone belt. This belt consists mainly of mafic volcanic metamorphosed to greenschist facies. The Belleterre property and its immediate vicinity host numerous precious metal (gold and silver) and base metal (copper, zinc and nickel) showings, associated, for the most part, to locally sheared quartz veins and to sulphide zones. The host rocks consist mainly of volcano-sedimentary rocks of intermediate to mafic composition, which are locally carbonatitized and silicified.
Auriferous quartz veins with pyrite laminations hosted in volcanic rocks are present on the property. Sericite-chlorite-pyrite shear zones cut by quartz veining are also auriferous. The mineralization is disseminated and locally in stringers of pyrite, sphalerite and galena.
• In 1941, the Chief showing (Veins 1, 2 and 3) was discovered. Two drill holes intersected this showing and the best results are: 8.20 g/t Au over 1.50 m and 51.40 g/t Au over 1.50 m
• In 1942, a bulk sample of 136 kg was collected from Veine no. 2 and yielded values of 130.21 g/t Au, 231.43 g/t Ag
• In 1994, a bulk sample of 18.20 kg was collected from Veine no. 1 aand yielded values of 74.06 g/t Au, 416.00 g/t Ag
Various work yielded the following results:
23.66 g/t Au sur 1.19 m (channel)
7.68 g/t Au sur 0.31 m (B89-1)
6.58 g/t Au sur 1.10 m (B89-3)
3.75 g/t Au et 10.80 g/t Ag sur 1.09 m (BE-06-04)
3.35 g/t Au et 10.20 g/t Ag sur 0.80 m (BE-06-08)
4.64 g/t Au et 11.90 g/t Ag sur 0.70 m (BE-06-09)
• In 1984, the Road-cut/Boudrias showing was discovered with a select sample yielding 235.88 g/t Au
• In 1996, on the Guillet showing, two selected samples collected in trenches #1 and #2 yielded values up to 19.41 g/t Au and 43.35 g/t Au, respectively
• In 2004, NioGold collected select samples from three historic trenches of the Guillet showing returning the following best Au results: 36.80 g/t, 5.68 g/t and 5.33 g/t
• In 2015 Khalkos Exploration acquired 50% of the property
