High-purity silica
Silicon metal is a strategic high-tech commodity that is produced by smelting high-purity silica with carbon (coal, charcoal). It has applications in the production of photovoltaic cells, computer chips and diverse range of high-tech products that increase efficiency and reduce energy consumption.
The demand for silicon metal is increasing exponentially due to high-tech and renewable energy applications of the commodity.
MHM owns two areas of high purity silica mineralisation in Tasmania that are prospective for use in silicon metal production;
Sorell Silica Project
Comalco (now Rio Tinto Aluminium) previously delineated four project areas suited to silicon metal production, significant potential to upgrade both purity and tonnage.
Unique “world-class” deposit with respect to magnitude and purity.
Silica displays excellent thermal stability and mechanical strength - critical factors in suitability for use to produce silicon metal.
Drilling to confirm tonnage and grade to JORC compliance subject to positive news regards potential offtake.
Marrawah Silica Project
Reported purity and tonnage potential within specifications.
Adjacent to sealed roads, excellent proximity to international ports.
