Broadway eyes porphyry discovery in Montana

VANCOUVER — Broadway Gold Mining (TSXV: BRD; US-OTC: BDWYF) is big-game hunting at its Madison gold-copper property in the historic Butte-Anaconda mining district around 38 km due southeast of Butte, Montana. The company picked up the 8-km² project package – which includes the dormant Broadway mine and contiguous Madison concessions – in late 2016. The site saw underground mining from the 1880s through 1950s, which yielded around 408,000 tonnes of material at an average grade of 9.1 grams gold per tonne. In the mid-2000s, Coronado Resources invested roughly US$10 million to trial mine at Broadway under small miner exclusion regulations. The project infrastructure includes a crushing plant, certified weight scale and grid power. The mine development ran to around 229 meters vertical depth and 610 meters laterally.
