West High Yield Resources (TSXV: WHY) is concentrating on metallurgical work for its Record Ridge magnesium deposit near Rossland, B.C. The company has initiated the final stage of the permitting process that was previously on hold due to financial challenges and the Covid-19 pandemic.
Tests done by Kingston Process Metallurgy (KPM) in 2019 demonstrated that the ore can be successfully leached using a proprietary hydrochloric acid process to produce a magnesium chloride solution. The solution can be purified to more than 99% MgCl2 by weight and used to produce saleable magnesium oxide and magnesium hydroxide.
This year metallurgical work continued with lab-scale tests to validate the flowsheet for the production of nickel chloride, nickel oxide, iron oxide and silica as well as magnesium oxide and hydroxide. A technical grade (98%) and a high grade (99%) magnesium oxide have been achieved by a spray roasting, washing and calcining process.
KPG recommended further tests to optimize the various nickel, silica and iron by-production, followed by preliminary engineering and costing work ahead of a pilot demonstration plant for the process.
WHY has drilled off measured and indicated resources of 43 million tonnes grading 24.6% magnesium at Record Ridge, and the deposit remains open in all directions.
