CUSIP: 39141Y 10 3

SASKATOON, Sept. 25, 2012 /CNW/ - Great Western Minerals Group Ltd. ("GWMG" or the "Company"), (TSXV: GWG) is pleased to announce it will undertake a Preliminary Economic Assessment ("PEA") for its Hoidas Lake rare earth project based on promising large-scale lab results.

Combined beneficiation/metallurgical test work has successfully produced a rare earth rough concentrate as well as a phosphate concentrate. That was followed by further hydrometallurgical test work that produced a mixed rare earth carbonate and fertilizer that can either be saleable products or used for further rare earth separation.

The large-scale lab results received from the Chinese institute with which GWMG has been working during the past two years included the following:

(Summary report at

  • The test results for the magnetic separation-flotation process indicate that the total rare earth recovery in the rare earth and apatite concentrates is 89.45%.
  • The hydrometallurgical treatment of the rare earth rough concentrate included sulfuric acid roasting, water leaching, double-salt precipitation, caustic soda transformation, hydrochloric acid selective dissolution, radium removal and precipitation by ammonium carbonate. It resulted in a rare earth recovery of 78.62% in the produced mixed rare earth carbonate.
  • Extraction of rare earths and phosphorus from apatite concentrate using the developed process included nitric acid treatment, neutralization and precipitation, sulfuric acid roasting of the residue, water leaching and preparing rare earth product, plus gypsum precipitation and liquid ammonia neutralization of the filtrate. It resulted in a rare earth recovery of 78.64% in the produced mixed rare earth carbonate.
  • The combined beneficiation-metallurgical process resulted in an overall rare earth recovery of 70.33%, comprised of 38.68% from rare earth rough concentrate and 31.65% from apatite concentrate. The phosphate recovery from the apatite concentrate was 92.5% in the produced Nitrogen-Phosphorous complex fertilizer. The specifications of both the mixed rare earth carbonate and the fertilizer, according to GWMG's preliminary assessments, meet market requirements.

GWMG President and Chief Executive Officer Jim Engdahl said, "The promising test results for our Neodymium-enriched Hoidas Lake project have confirmed the validity of our original assumptions on the processes that are most likely to be successful. The positive results from the large-scale lab work have led GWMG to move ahead with a PEA for Hoidas that will also address the issues of its remote location now that we have removed the metallurgical bottlenecks from the project."
