iconic minerals, nv

In 2021, GRE created an NI 43-101 Preliminary Economic Assessment (PEA) for the Bonnie Claire lithium project in Nevada.  GRE is currently involved in advancing this work into a Pre-Feasiblity Study.  This project involved the following elements: Calculation of a mineral resource estimate; Creation of a mine plan for lithium-rich clay extraction; Design of a metallurgical testing program and a metallurgical plant, and Creation of an economic model
To access deeper high-grade lithium, GRE evaluated the use of innovative borehole mining methods which will allow for the exploitation of the high-grade lithium clays below lower-grade cover.  


GRE’s team is working with Bonnie Claire and a respected metallurgical lab to design the process flowsheet for producing battery-grade lithium carbonate.   The first sample of battery-grade lithium carbonate has been produced.  GRE will be the lead author on the upcoming Pre-Feasibility Study.   

clayton valley

century lithium, nv

Century Lithium owns 100% of the Clayton Valley Lithium Project  totalling 5,585 acres in west central Nevada, USA. Exploration and development by Century led to the discovery of an extensive resource of lithium-bearing claystone, immediately adjacent to the lithium brine basin in the valley. The lithium resource is exposed at surface, sheltered from erosion by Angel Island, an outcrop of Cambrian metavolcanic and clastic rocks, protruding through the Pliocene lakebed sediments.
