Vancouver, BC – Orex Minerals Inc. – (TSX-V: REX) (“Orex”), has received preliminary metallurgical test results for samples from the Main Zone of the Boleras Silver Deposit at the Sandra Escobar Project in Durango, Mexico. This project is being advanced by Orex under an option agreement with Canasil Resources Inc. – (TSX.V: CLZ) (“Canasil”). Results are now available for five samples, with increasing head grades, taken from across the Main Zone of the Boleras Silver Deposit. These results illustrate that recovery is grade dependent. A portion of the silver-bearing mineralogy is recoverable with leaching techniques, including hydrochloric acid (HCl), or sulphur dioxide (SO2) pre-treatment before cyanidation, and a portion is refractory, requiring more investigation. An extra high-grade sixth sample was also prepared for mineralogical work and was tested by the same methods at the Kemetco Research Inc. (“KR”) laboratory.
