Project Background

La Parrilla is a large scale, low-cost, long life Tungsten and Tin Mine.

The project has an Australasian Joint Ore Reserves Committee (“JORC”) compliant resources total 49 million tonnes (“mt”) at a grade of 998 parts per million (“ppm”) tungsten trioxide (“WO3“) and JORC compliant reserves of 29.8mt at a diluted grade of 931ppm WO3.

With its core infrastructure in place, the site is accessed directly from the highway along a 3km asphalt road and is serviced by electricity and water. Importantly, the mine is located within a short trucking distance from both the Atlantic and Mediterranean ports.


Production started in December 2018 and with financing and key contracts all in place, development work is on track. The ramp-up phase, to mine 2 mtpa of Run of Mine and produce approximately 2,700 tonnes of tungsten concentrate and 500t of tin (Sn) concentrate per annum, is near completion.
