Mkango Resources (TSXV:MKA) said on Monday that it has completed leach optimization test work, adding to an ongoing prefeasibility study on its Songwe Hill rare earth project in Malawi.
According to the Calgary-based company, leaching with diluted (20%) hydrochloric acid at ambient temperatures for 30 minutes achieved good recoveries, especially for critical and heavy rare earths, which has good implications for plant design and capital expenditures.
As quoted in the press release:
William Dawes, Chief Executive of Mkango, stated “This is a further milestone towards completion of the pre-feasibility study, targeted for first quarter 2014. The pre-feasibility study is based on the previously defined Indicated mineral resource so no further drilling is anticipated in the near term. Songwe hosts a major strategic resource of rare earths in Malawi, with the critical rare earths, neodymium, dysprosium, europium, terbium and yttrium, accounting for circa 70% of the gross in-situ value at current prices, and praseodymium accounting for a further 15%.”
