Name of the Project
Halfmile-Stratmat massive sulphide zinc/lead/silver project.

Location
The project is located in the Bathurst Mining Camp of New Brunswick, Canada.

Client
Trevali Mining.

Project Description
A preliminary economic assessment (PEA) has determined that, under the base case, ore from the Halfmile and Stratmat deposits will be fed to a new 3 000 t/d concentrator plant at the Stratmat site.

The alternative case PEA envisages the transport of preconcentrated dense-media feed to Trevali’s Caribou concentrator plant.

For both cases, the PFS envisages a mine life of 13 years, with peak early payable production of about 117-million pounds of zinc, 35-million pounds of lead, two-million pounds of copper and 766 000 oz silver.

The Halfmile deposit has measured and indicated resources of 7.8-million tonnes grading 2.35% lead, 6.94% zinc and 36 g/t silver. The deposit includes inferred resources of 6.5-million tonnes grading 1.51% lead, 5.62% zinc and 23 g/t silver.

The Stratmat deposit has an indicated resource of 4.7-million tonnes grading 2.1% lead, 5.3% zinc and 49 g/t silver, and an inferred resource of 2.4-million tonnes grading 2.1% lead, 4.8% zinc and 39 g/t silver.

Potential Job Creation

Net Present Value/Internal Rate of Return
Under the base case, the project has a post-tax net present value (NPV), at an 8% discount rate, of C$99-million and an internal rate of return (IRR) of 19%, with a payback of 3.6 years.

The alternative case indicates a post-tax NPV, at an 8% discount rate, of C$116-million and an IRR of 25%, with a payback of 2.6 years.

Value
The base case estimates preproduction capital at C$231-million. The alternative case estimates preproduction capital at C$156-million.
