México.- La empresa mexicana Autlán informó que posee las reservas de manganeso de grado metalúrgico más grandes de América del Norte, que representan, a su vez, prácticamente todas las que se han descubierto en México.
Las operaciones de Autlán se llevan a cabo en las minas de Molango, Naopa y Nonoalco, localizadas en el distrito manganesífero de Molango en el Estado de Hidalgo.
Este distrito cubre un área de aproximadamente 1,250 kilómetros cuadrados y contiene los depósitos de mineral de manganeso de grado metalúrgico más importantes de América del Norte, según el U.S. Geological Survey.
Las reservas de Autlán constituyen casi todas las reservas probadas de manganeso en México con base en los Informes Anuales de la Cámara Minera de México (Camimex).
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.
