TriAusMin is a company focussed on base and precious metals exploration and project development in New South Wales, Australia.

This long term exploration commitment to the Lachlan Fold Belt of NSW extends back to October 1993, when the Company was formed and first started exploring the region. The understanding of the region has evolved over time and now allows the Company to capitalise on opportunities within what we believe to be a world-class base and precious metals province.
