Wolfden Resources of Thunder Bay, Ontario, has drilled a second hole into the high grade Footwall zone and – like the first one – it encountered polymetallic mineralization in Penobscot County. Assays are pending.
The new hole – a wedge drilled off the discovery hole – confirms that the Footwall zone is a steeply dipping lens and has a horizontal width of 3.5 metres at 625 metres below surface. The first hole, PM-18-031 intercepted 16.8% zinc and 8.4% lead (or 38.2% zinc equivalent) over 4.1 metres.
The mineralization is a disseminated to semi-massive sulphide with appreciable sphalerite and galena and lesser amounts of chalcopyrite and pyrite contained within a silica-iron carbonate-bearing volcanic exhalative horizon.
Wolfden notes that the Picket Mountain deposit is one of the highest grade polymetallic projects in North America. In January 2019 and using a 9% zinc equivalent cut-off, the indicated resource was 2.1 million tonnes grading 10.77% zinc and 4.29% lead. The inferred portion is 2.0 million tonnes grading 10.98% zinc and 4.35% lead.
