Amec Foster Wheeler to conduct Rhyolite Ridge PFS

Global Mining Review,

Australian-based lithium-boron mine developer Global Geoscience Ltd has appointed Amec Foster Wheeler (Amec, part of Wood plc) as the engineering and design firm to complete the Pre-Feasibility Study (PFS) for the Rhyolite Ridge Lithium-Boron Project in Nevada, USA.

Amec is a major leader in global mining solutions with a mining team consisting of more than 4000 people. The Amec technical team that will work on the Rhyolite Ridge PFS has extensive experience that is highly relevant to the project including:

  • Extraction and processing of lithium and boron ores in Chile, Argentina, United States, China and Serbia from the full range of brine, spodumene and sedimentary deposits.
  • Processing and refining of lithium to produce battery-grade lithium carbonate and lithium hydroxide.
  • Production of sulfuric acid at mining operations.
  • Leaching, evaporation, crystallisation, purification and solvent extraction relating to lithium and other salts.
  • Open pit mining and financial analysis in Nevada.
  • Heap leach processing and tailings management in Nevada and elsewhere.

According to Global Geoscience, a key aspect of Amec’s selection was its strong technical team and recent experience in lithium projects, including a sedimentary lithium-boron deposit like Rhyolite Ridge. Global Geoscience’s Senior Vice President of Engineering and Operations, Matt Weaver, said: “Amec’s capabilities and strong technical team are an exceptionally good fit for the Rhyolite Ridge PFS. Amec has completed numerous studies for mining projects in Nevada as well as relevant studies for various lithium and boron projects globally.”

Global Geoscience’s Managing Director, Bernard Rowe added: “Amec was chosen because of their capabilities, integrity and proven track record of delivering value. In December 2017, we announced the positive outcomes from the initial Rhyolite Ridge mining study and favorable 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.”
