Allied Nevada Targets 450K oz/y of Gold by 2018
Allied Nevada has reported the results of a pre-feasibility study (PFS) for a proposed expansion at its Hycroft mine in northwest Nevada. The PFS assumes a two-phase construction program that would first result in mill throughput capacity of 60,000 short tons per day (st/d); a second phase would increase it to 120,000 st/d. An increase in the mine’s loading and haulage fleet would take place starting in 2017 to assure an adequate supply of ore to the expanded facilities. As a result of successful ambient alkaline oxidation (AAO) pilot plant work, onsite oxidation of sulphide concentrate...... read

Capstone Studies Pinto Valley Mine Life Extension
Capstone Mining has announced the results of a pre-feasibility study (PFS) for a mine-life extension of its Pinto Valley openpit mine in the Globe-Miami mining district of Arizona that extends the mine life by eight years from 2018 to 2026. Under the new operating plan, designated PV2, Pinto Valley will produce an average of 128.4 million lb/y of copper contained in concentrate and 6.6 million lb/y of copper cathode during the first five years of operation. Life-of-mine production will average 119.5 million lb/y of copper contained in concentrate plus 6.3 million lb/y of cathode copper, as well as 1.4 million lb/y of molybdenum and 235,000 oz/y of silver credited to concentrate.... read more

Alliance Reports Another Record Quarter
Officials at Alliance Resource Partners have announced strong Q1 2014 operating results, including 25% increases in the Appalachian region, culminating in 14 years of consecutive growth. The numbers, according to CEO Joe Craft, were driven by a major longwall move at the Tunnel Ridge operation and early production at the new Gibson South mine. "Collectively, our operations were able to operate efficiently despite severe winter weather," he added. Weather-related transportation disruptions in the Illinois Basin and cessation of operations at Pontiki in Q4 2013, however, resulted in lower Q1 2014 sales, despite higher sales volumes from the longwall …. read more

MSHA Issues Final Coal Dust Rule
In response to a rebound in both the number of cases and severity of pneumoconiosis, or black lung disease, U.S. Mine Safety and Health Administration (MSHA) officials have released a final rule on new allowable respirable dust levels for the coal mining industry. The final rule indicates a 25% reduction in permitted levels of breathable coal dust to 1.5 from 2 milligrams per cubic meter of air. This also halves the standard to 0.5 from 1 for certain mine entries and miners with pneumoconiosis. Dust samples, meanwhile, will now be mandated whenever mines operate at 80% of production— up from 50%; the new level, MSHA officials said, is "more representative of actual working conditions." …. read more
