Chase Mining Corporation Ltd (ASX:CML) has received a conditional offtake offer to supply between 2,000 and 5,000 tonne of topaz concentrate per month from its Torrington Project in NSW.

This follows exhaustive quality testing of a bulk sample of the nominally 97% topaz concentrate by an international abrasives supply company as a high-pressure water cutting abrasive feedstock.

The material supplied by Chase is representative of what would be produced by a proposed gravity recovery plant from the present flowsheet with a minus 1 mm silexite feed from Torrington.
