Calibre Mining secures approval for third open pit at Valentine
Miner announced on Tuesday the approval of a third open pit at its Valentine Gold Mine.
Great Atlantic Resources (TSXV:GR) announced that it has recently located tungsten mineralization in a new target area at its 100%-owned South Quarry property, located in east-central Newfoundland, Canada.
In a press release, Great Atlantic explained that the tungsten mineralization occurs in quartz-dominant veins in bedrock at a historic trench / stripped area.
Great Atlantic also expanded the South Quarry property from 1,350 to 1,925 hectares
“This site is within the northern region of the property and northeast of the quarry referred to as the South Quarry,” the media brief states.
According to the Vancouver-based company, tungsten-bearing pegmatite veins are widespread in the northern region of the property including the South Quarry and an adjacent smaller quarry.
Back in 2015, the miner confirmed high-grade tungsten mineralization in veins in rubble and bedrock at the two quarries. Eleven rubble grab samples exceeded 5% WO3 and a 20-centimeter long channel sample along a 15-centimeter wide vein 2.96% WO3.
Tungsten is rare metal usually alloyed with other minerals to produce military equipment, incandescent light bulb filaments, X-ray tubes, electrodes in gas tungsten arc welding, superalloys, and radiation shielding.
