The Ruttan deposit contains a NI-43-101 compliant inferred resource of 19.75 million tons of 1.17% Cu, 1.47% Zn and remains open for expansion to depth, beneath previous mine workings, and in the hanging and footwall zones.

Volcanic Massive Sulphide (VMS) deposits such as Ruttan are considered to rarely occur in isolation and form camps or clusters of deposits.

Trevali believes that the Ruttan deposit and immediate underexplored region holds good to excellent exploration potential.

The majority of the former mine infrastructure remains in place including tailings management facility, water treatment plant, power, road/rail and the town of Leaf Rapids that was built to service the former mine.

In Canada, the firm owns the Halfmile zinc-lead-silver mine and Stratmat polymetallic deposit, and has entered into a definitive agreement to acquire the Caribou Mine and Mill.
