Pacific Rim Cobalt Embarks on Processing Options Study

The review is expected to be completed by March 31, 2018 and will include:

1) Descriptions of previous plants that have treated similar material with specific focus on recovery of nickel and cobalt values

2) Descriptions of processes that could be used for the material-type but have not been built at a commercial level

3) Identification of pros and cons for each process flowsheet reviewed

4) Recommendations for future work to minimize testing and quickly focus on 1 or 2 flowsheet options for further investigation.

MSM's principal is considered to be a global leader in extractive metallurgy of copper, cobalt and nickel, having written the book "Extractive Metallurgy of Nickel, Cobalt and Platinum Group Metals".

Ranjeet Sundher, Pacific Rim Cobalt's President and Chief Executive Officer, said, I believe we have an exceptional opportunity to build a company in the battery metals sector. Pacific Rim Cobalt plans on creating significant shareholder value by leveraging the "once in a lifetime" global shift from fossil fuels to renewable energy.

Demand for nickel and cobalt is expected to increase as production and adoption of electric vehicles (EVs) and their lithium-ion battery packs continue to grow. The EV market utilizes three principal battery types: lithium-cobalt-oxide (LCO), nickel-manganese-cobalt (NMC) and nickel-cobalt-aluminium-oxide (NCA), which utilize nickel and cobalt.
