NEVADA — Rocmec Mining, based in a suburb of Montreal, says it has signed an agreement for the use of its thermal fragmentation rock breaking technology in the Midas underground gold mine 100 km northeast of Winnemucca. The mine is owned and operated by Newmont Mining of Denver.
Rocmec will use its thermal fragmentation mining method rather than explosives to break up ore and recover a narrow-vein stope over an initial distance of 183m, which is currently available. The company aims to deliver the advantages of the thermal fragmentation such as reduced dilution, increased productivity, and lower production costs.
Ore from the Midas mine is processed by conventional milling and Merrill-Crowe zinc precipitation.
