The Gilmour Brook South zinc-lead prospect is located about 20km south-southeast of the Brunswick No 12 mine. It is hosted within the Brunswick Horizon, at the top of the Nepisiguit Falls Formation, and exhibits mineralization in the style and type as that found both at the Brunswick No. 6 and No. 12 mines. This “Brunswick Horizon” sulphide mineralization is commonly present as semi-massive to massive occurrences of stratiform zinc-lead sulphide mineralization that has been intersected intermittently over a strike of 1400 m and locally to vertical depths of 700 metres. Historical drilling by Noranda Exploration during the period 1998 to 2000 intersected significant grade and widths of zinc-rich mineralization in two lenses approximately 400 metres apart.
In November 2017, Osisko Metals began a drill program at the Gilmour South Project. The objective of the drill program is to increase historical resources and to upgrade them to comply with NI43-101 regulations. A key part of this effort will be to investigate the potential for the thickening of the high-grade sulphide mineralization along previously unrecognized structural corridors that are typically associated to the major deposits in the BMC.
The historical estimates contained in the Gilmour South Project Map were obtained from the New Brunswick Government Mineral Deposits database. Readers are cautioned that Osisko Metals has not completed the work required to independently analyze and verify the results of previous operators nor has a qualified person done sufficient work to classify the historical estimates as current mineral resources or mineral reserves. Osisko Metals is not treating the historical estimate as current mineral resources, and it believes these historical estimates provide an indication of the potential of the property and are reported because they are deemed relevant to the description of the properties.
