Delineated deposit with some historic open-pit production.



In April 2018 Trevali entered into an Option Agreement to earn a 75% interest in the Murray Brook Deposit from Puma Exploration.

The Murray Brook Deposit, which comprises 484 hectares under mining lease 252, has a currently defined measured mineral resource of 3.68 million tonnes grading 5.57% Zn, 1.87% Pb, 0.36% Cu, 70.5 g/t Ag and 0.56 g/t Au, plus indicated mineral resources of 1.60 million tonnes grading 4.48% Zn, 1.63% Pb, 0.70% Cu, 65.3 g/t Ag and 0.88 g/t Au (for a combined measured and indicated resource of 5.28 million tonnes averaging 5.24% Zn, 1.80% Pb, 0.46% Cu, 68.9 g/t Ag and 0.65 g/t Au containing approximately 610 million pounds of zinc, 209 million pounds of lead and 11.7 million ounces of silver) as of December 21, 2016. The core of the mineral resource occurs in the west zone (zinc-lead) which is 200 metres wide, extending from surface to 300 metres vertical, and the true thickness of the massive sulphide body varies from 75 metres to 100 metres. The east zone (copper-gold) is 100 metres wide, also extending from surface to 300 vertical metres and is mainly mineralized with gold and copper.
