Using a 5% ZnEq cutoff, the resource estimate prepared by SRK Consulting (Canada) Inc., returned 4.70 million tonnes grading 5.31% zinc, 2.07% lead, 0.41% copper, 48.52 g/t silver and 0.59 g/t gold in the Indicated category and 2.40 million tonnes grading 4.76% zinc, 2.07% lead, 0.70% copper, 38.82 g/t silver and 0.42 g/t gold in the Inferred category.

Indicated Resource of 4.7 million tonnes grading 5.31% Zn, 2.07% Pb, 0.41% Cu, 48.52 g/t Ag and 0.59 g/t Au, and an Inferred Resource of 2.40 million tonnes grading 4.76% Zn, 2.07% Pb, 0.70% Cu, 38.82 g/t Ag and 0.42 g/t Au; using a 5% ZnEq cutoff

The large Volcanogenic Massive Sulphide deposit consists of at least five discrete mineralized zones that span a distance of over 2 kilometres. The multi-lens, multi-zone deposit remains open for expansion at depth and the Company considers the exploration potential good-to-excellent.

"The resource estimate has successfully increased the Companies confidence in the Stratmat deposit and added significant new tonnage, all very important for the next phase as Trevali advances its growth plans for the Bathurst Mining Camp" stated Dr. Mark Cruise, Trevali’s President and CEO.

The results from this SRK study will be incorporated into a planned Preliminary Economic Assessment update scheduled for later this year.
