Brixton Metals Corp. TSX-V: BBB has released additional drill results from its wholly owned Hudson Bay project located in the Ontario’s cobalt camp.
Figures associated with this news release are available on-line.
Highlights from six drill holes:
- Drill hole HB18-06 intersected 6.70 metres of 625.80 grams per tonne silver, 0.26 per cent copper, 0.45 per cent zinc and 0.12 per cent lead (937.29 g/t silver equivalent) from 36 m depth;
- Drill hole HB-18-04 intersected three m of 0.22 per cent cobalt and 0.48 per cent Cu, 17.3 g/t Ag (0.25 per cent cobalt equivalent) from 46 m depth;
- Drill hole HB-18-05 intersected 0.71 per cent Co, 10.3 g/t Ag, 0.46 per cent nickel, 0.37 per cent Zn (0.80 per cent Co Eq) over one m from 56 m depth;
- Drill hole HB18-07 intersected five m of 236.36 g/t Ag, 0.04 per cent Co, including 2,050 g/t Ag and 0.42 per cent Co (2.24 per cent Co Eq) over 0.50 m from 56 m depth.
Chairman and chief executive officer of Brixton, Gary Thompson, stated: “We continue to have success from our first drill campaign at the Hudson Bay project. The intercepts are at shallow depths 36 to 57 metres deep. For reference, 1 per cent cobalt is equivalent to 12 per cent copper or 1,600 g/t silver. We see the potential for both high-grade narrow veins and broad low-moderate-grade disseminated mineralized zones.”
The reported drill holes have confirmed the presence of additional cobalt and silver mineralization at the Hudson Bay project. Significant cobalt mineralization was intersected in drill holes HB-18-04 and HB-18-5 and consists of cobalt, nickel and copper minerals as disseminated and centimetres-wide veinlets. The mineralization is hosted in locally brecciated and chloritized cherty mafic-intermediate pillows (Archean volcanics). It appears that the cobalt mineralization intersected in drill holes 04 and 05 are part of a northwest-trending cobalt mineralization system that was also intersected in holes 01 and 03 (see Feb. 20, 2018, news release) that wasn’t previously mined out.

Cobalt equivalent values (Co Eq) were calculated using the formula Co Eq equals $17 times Ag g/t divided by 31.104 plus $3 times per cent Cu divided by 100 times 2,204.63 plus $28 times per cent Co divided by 100 times 2,204.63 plus $5.50 times per cent Ni divided by 100 times 2,204.63 divided by $28 divided by 2204.63 times 100. This method assumes full metal recoveries. Metal prices used in this calculation include: $17 per ounce for Ag, $3 per pound for Cu, $5.5 per pound for Ni and $28 per pound for Co. Silver equivalent values (Ag Eq) were calculated using the formula Ag Eq equals 17 tims Ag g/t divided by 31.104 plus $3 times per cent Cu divided by 100 times 2,204.63 plus 28 times per cent Co divided by 100 times 2,204.63 plus 5.50 times per cent Ni divided by 100 times 2,204.63 divide by 17 times 31.104. This method assumes full metal recoveries.
Drill hole HB-18-06 was drilled 76 metres northwest from drill hole HB-18-01 (1 per cent Co over 0.8 m, reported in Feb. 20, 2018, news release) and was successful in identifying silver and copper mineralization. See the associated table for highlights of the assays results from drill hole HB-18-06.

Drill hole HB-18-07 was designed to test the extension to the south of the silver-cobalt mineralization historically mined by previous operators. The drill hole intersected significant silver-cobalt mineralization and consisted of 2,050 g/t Ag and 0.42 per cent Co over 0.5 m. The mineralization consists of cobalt and silver minerals associated with chalcopyrite and arsenopyrite hosted in Huronian conglomerate.

About the Langis and Hudson Bay silver-cobalt project
Brixton’s wholly owned Langis and Hudson Bay past-producing mines are located 500 kilometres north of Toronto, Ont. The cobalt-silver mineralization occurs as steeply-to-moderately and in some cases shallow-dipping veins and as disseminations within any of the three main rock types: Archean volcanics, Coleman Member sediments and Nipissing diabase. The Langis mine produced 10.4 million ounces of silver at 25 ounces per ton Ag and 358,340 pounds of cobalt, and the Hudson Bay mine produced 6.4 million ounces of silver at 123 ounces per ton Ag and 185,570 pounds of cobalt. Historically, the cobalt camp produced 50 million pounds of cobalt as a by-product of 500 million ounces of silver production, and includes nickel and copper by-products.
