The PAK deposit shares the differentiating characteristic of being low-iron spodumene to the world-class Greebushes’ deposit in southwestern Australia. The new PEA for the project includes a conversion facility to be able to  capitalize on a larger piece of the value chain.

The deposit is outcropped at the earth’s surface and is amenable to low-cost open pit mining. It is an LCT (lithium- cesium- tantalum) type pegmatite (coarsely crystalline granite or other igneous rock with crystals several centimeters to several meters in length). The deposit is a large intrusion, with internal zonation (defined mineralogical assemblages) and high concentration (PAK maintains the highest known grades in North America). These types of pegmatites have been the principal source of hard rock lithium, tantalum, rubidium and cesium ores mined in the world but there are few commercially-viable deposits.
