The Brunswick Belt project is composed of four (4) claim groups totaling 586 claims that cover approximately 12,892 hectares (129 km2). It is located roughly 25 km south west of the city of Bathurst, and covers the continuation of the mineralized horizon that hosts the original world-class Brunswick No. 6 and No. 12 mines immediately to the east. These mines produced zinc, lead and silver for over 50 years, and the mines were last operated by Glencore Canada until closure in 2013. The Brunswick No. 12 mine was the world’s largest underground zinc mine and produced 137 million tonnes grading 8.74% zinc, 3.44% Pb, 0.37% Cu, and 102 g/t Ag (1) over a period of 49 years.
Historically, a significant amount of exploration work was performed in the Brunswick Belt area by Brunswick Mining and Smelting, Noranda and its successors. At that time, the objective was to find additional mill feed for the Brunswick No.12 concentrator that produced at a rate of 10,500 tpd or approximately 3.5 million tonnes annually.
The Brunswick Belt warrants exploration for new deposits on the basis of new ideas and concepts developed by the Osisko Metals team, including the significance of mining smaller scale, standalone operations that would feed a central concentrator. Within this highly prospective brownfield area of the Brunswick horizon geology, a number of significant historical deposits exist and which have not been assessed in the context of the new global reality of current zinc markets.
