TSX Venture Exchange - Symbol: COL - Shares Outstanding: 102,994,527
TORONTO, ON. - NWM Mining Corporation 'NWM' (TSX-V: COL) is pleased to announce publication of an NI 43-101 compliant technical report for the Sierra Pinta past producing underground gold mine located in the northern part of the State of Sonora, Mexico.
The mine last operated in the 1950's and old workings extend along two high grade gold bearing Veins identified as the Dolores and La Pinta Veins. The Dolores Vein is a faulted offset of the La Pinta Vein. The report states that "Both of these Veins are open and have excellent potential to host additional mineralization down-dip. Additional exploration potential exists to the west of the known Dolores Vein and to the east of the La Pinta Vein."

The report provides that laboratory tests have outlined very favourable overall gold recovery characteristics for Vein material, stating "Laboratory scale tests on three samples using a combination of processing through a Knelson Concentrator followed by cyanide leaching of the resulting tails returned overall total gold recovery of 98.0% to 99.6%. Three bulk samples were found to have head grades of 42.8, 27.3 and 24.7 g/t Au."
A summary of both Channel and Panel sample tests from the report include:
"The grade and recovery characteristics for Vein material from the past producing underground gold mine at Sierra Pinta are very favourable. The report suggests that this is a highly prospective gold bearing property which is in geologic proximity to the Herradura mine and the new Dipolos and Solidad discoveries," said Chris Berlet, CEO of NWM Mining Corporation.
The NI 43-101 report recommends a two phased development approach. The recommendations include underground diamond drilling as well as development mining and further sampling in progression of a feasibility study to support mining operations on the property.
