As part of the Granite Mountain complex, the dominant rock here is hornblende-biotite tonalite, a granitic, which is an intrusive igneous rock consisting of feldspar, quartz, mica and/or amphibole ...

The basement rocks returning the highest lithium concentrations are identified as biotite schist and amphibolites with the majority of these samples in close proximity to their contact points with ...

Within the schist occurred sediments with alteration and mineralization at 124.7-153.2m and 186.5-198m, in additional a complex zone from 216-240.8m included talc schist, biotite schist and the ...

The first rock type, found along the ridge line of this prospect, is a biotite-hornfels-schist that is in contact with the granitoids beneath.
