Broadway Gold Mining Ltd. (“Broadway” or the “Company”) is pleased to announce that it has contracted Groundhog Mining of Dillon, MT to immediately commence rehabilitation of the underground workings at Broadway’s Madison copper and gold project (“Madison”). The rehab work will enable the Company’s technical and operational team to access underground workings from which high-grade copper-gold mineralization was previously mined and Broadway believes there is potential for additional ore in these stopes. By shoring up the drifts and stopes, Broadway will be in a position to commence with a systematic sampling program including underground drilling as a first start of building a reserve, if deemed economically feasible, for future mining.
Previous Underground Results
Past sampling of the 600-level drift returned average grades of:
- 0.429 ounces per ton (oz/t) Au with 155 truck grab samples and 13 chip or channel samples ranging from 0.010 to 2.728 oz/t Au.
Sampling from the 600-level stopes returned grades from:
- 0.012 to 0.272 oz/t Au averaging 0.088 oz/t Au from 23 truck grab samples and 10 chip or channel samples; and,
- 0.012 to 1.924 oz/t Au averaging 0.663 oz/t Au from 45 truck grab samples and one chip sample.
Seven underground drill holes into the 600-level stopes returned grades ranging from:
- 0.272 oz/t Au across 11.5 feet in hole U10-03 to hole U10-02, which returned 74 feet at 0.743 oz/t Au.
Underground Work Underway
Concurrent to rehabilitation of the historic workings, planning for underground exploration at Madison is underway. The Company’s geological team is conducting baseline studies and compiling all historic data to support the exploration program design. Systematic sampling is planned to include multiple underground drill holes scheduled to commence in Q1 2017. This drilling would test the down dip continuation of gold mineralization at the bottom of the mine workings, below the lowest level of the Broadway Mine.
Situated within Broadway’s Madison project, the Broadway Mine operated from the 1880s to the 1950s and produced an estimated 144,000 ounces of gold (450,000 tons averaging 0.32 oz/t gold) from 6,000 feet of underground workings to a vertical depth of 750 feet. The deeper porphyry targets remain untested.
Madison is located near Silver Star, Montana in the Butte-Anaconda mining region, southwest of Montana’s world famous Butte copper mine. Major producers in the area include Barrick Gold’s Golden Sunlight gold mine and Montana Resources’ Continental Pit copper mine.
All intersections are core widths that were not converted to true widths by the previous owner. All noted underground and core assaying was completed by Norris Laboratory of Norris, Montana, a non-ISO facility, with occasional check sampling done by the ISO-accredited ALS Minerals Lab in North Vancouver, BC.
