SnapshotCarolina Lithium will be one of the world’s largest and lowest cost producers of lithium hydroxide.

Piedmont Lithium has nearly completed a rigorous process to obtain our state mining permit, which began in August 2021 with the North Carolina Department of Environmental Quality.

Deposit type

  • Pegmatite

Summary:

The mineralised pegmatites are thought to be concurrent and cross-cutting dike swarms extending from the Cherryville granite. As the dikes progressed further from their sources, they became increasingly enriched in incompatible elements such as lithium (Li) and tin (Sn). The dikes are considered to be unzoned.

Within the Project, spodumene pegmatites are hosted in a fine to medium grained, weakly to moderately foliated, biotite, hornblende, quartz feldspar gneiss or commonly referred to as amphibolite. The spodumene pegmatites range from fine grained (aplite) to very coarse-grained pegmatite with primary mineralogy consisting of spodumene, quartz, plagioclase, potassium-feldspar and muscovite.

Three main zones of mineralisation have been extensively drilled leading to Indicated and Inferred Mineral Resource classifications. The largest is in the western portion of the property, known as the B-G Corridor, where close spaced drilling has identified mineralisation for 1,400 metres along strike and to a depth of 150 to 200 metres below surface. This corridor accounts for 54% of the total resource reported.

The F Corridor is the second largest area of mineralisation and accounts for 30% of the total resource reported. This corridor is located along the eastern portion of the property and also consists of multiple pegmatite dikes, these dikes have been drilled for 750 metres along strike and 150 to 200 metres below surface.

The third area, known as the S Corridor, is divided into two zones of mineralisation and accounts for the remaining 16% of the total resource reported.
