Mine developer Global Geoscience has appointed Amec Foster Wheeler for the Rhyolite Ridge Lithium-Boron Project in Nevada, US.
Amec will serve as engineering and design firm to complete the pre-feasibility study (PFS) for the project.
Global Geoscience owns a 100% interest in the Rhyolite Ridge project, which exhibits a large, shallow lithium-boron deposit.
The project is nearly 25km west of Albermarle’s Silver Peak lithium mine and 340km from the Tesla Gigafactory near Reno.
Lithium-boron mineralisation is found in the north and south sedimentary basins, which are 4km apart.
The Amec technical team has relevant experience in extraction and processing of lithium and boron ores in Chile, Argentina, and the US.
Global Geoscience managing director Bernard Rowe said: “In December 2017, we announced the positive outcomes from the initial Rhyolite Ridge mining study and favourable heap leach results.
“This work to date provides the foundation for the PFS and confirms that the large, shallow Rhyolite Ridge lithium-boron deposit is amenable to low-cost open-pit mining.
“Amec has the capability to rapidly progress the engineering and design work required to complete the Rhyolite Ridge PFS as targeted by mid-2018.”
Global Geoscience Engineering and Operations senior vice-president Matt Weaver said that Amec has completed several studies for mining projects in Nevada, in addition to relevant assessments for various lithium and boron sites worldwide.
