The ability of Re-2OX to achieve exceptionally high recovery rates for both cobalt and silver, plus nickel and copper, while also removing 99% of arsenic, expands the potential of the Castle mine.
Canada Cobalt Works Inc. (TSXV: CCW) (OTC: CCWOF) (Frankfurt: 4T9B) (the “Company” or “Canada Cobalt”), a technology leader in the Northern Ontario Cobalt-Silver Camp, is pleased to announce that the Company has made important breakthroughs in its proprietary and environmentally green Re-2OX process for the recovery of cobalt, precious metals and base metals.
As the electric vehicle supercycle intensifies, Canada Cobalt is the only company in Canada’s cobalt heartland to produce a technical grade cobalt sulphate test product from its own feed (refer to August 15, 2018, news release). Significantly, Re-2OX skips the normal smelting process to create battery grade cobalt sulphate while nickel- manganese-cobalt (NMC) battery grade formulations are also in the pipeline.
In addition, the ability of Re-2OX to achieve exceptionally high recovery rates for both cobalt and silver, plus nickel and copper, while also removing 99% of arsenic, expands the potential of the Castle mine given Phase 1 underground results released February 19, 2019, and a second phase starting soon. Furthermore, Re-2OX is a value-driver for the company’s planned tailings programs at Castle and elsewhere in the district, and will also be used by Canada Cobalt to immediately build a new model of “streaming” opportunities for the Company with respect to other battery metal projects while protecting the process.
Given the current optimization level of Re-2OX, and the growing importance of this hydrometallurgical process to Canada Cobalt and its shareholders, the Company has initiated the process of submitting a patent application for this proprietary metal extraction method.
Frank J. Basa, Canada Cobalt President and CEO, commented: “The fact that SGS has demonstrated that Re-2OX can very efficiently recover a broad set of metals from arsenic-rich material, ranging from low grade to high-grade, further de-risks the Castle mine project and expands opportunities to build shareholder value. Further Re-2OX optimization will target the recovery of gold.”
Quality Assurance/Quality Control
A hand-cobbed, 73-kilogram sample of waste material was taken from the Castle mine and crushed to negative- 10 mesh and then blended by SGS Laboratories in Lakefield, Ontario. From this, a representative sample was submitted for analysis by lead fusion fire assay for silver and gold. Other metals were assayed by ICP after multi- acid digestion. The material was subsequently used for testing the proprietary Re-2OX process. Canada Cobalt relies on internal SGS laboratory independent QA/QC, which allows the disclosure of the results provided.
