TORONTO (miningweekly.com) – Vancouver-based potash hopeful Potash One has appointed John McEwan as vice-president of solution processing, for the company's Legacy potash project, in souther Saskatchewan.

McEwan was previously the principal process engineer at Rio Tinto, and was involved in process and project engineering for feasibility studies and the recovery of potash from the mining giant's potash deposits in Argentina and Canada.

However, these assets have recently been sold to Brazilian miner Companhia Vale do Rio Doce.

“John provides a wealth of technical knowledge, 30 years of chemical processing which includes solution mine development experience,” said Potash One CEO Paul Matysek.

The company's Legacy project, in Saskatchewan, is currently in prefeasibility stage, and the firm expects to have the study completed by April or May this year, Matysek said last month.
