Trilogy Metals Inc. April 25 reported that the Arctic deposit at its Upper Kobuk Mineral Projects in Northwest Alaska now contains 2.4 billion pounds of copper and 3.4 billion lb of zinc in the indicated resource category, a roughly 40 percent increase for both metals. At a 0.5 percent copper-equivalent cut-off grade, the Arctic deposit is estimated to contain in-pit 36 million metric tons of in-pit indicated resources averaging 3.07 percent (2.4 billion lb) copper, 4.23 percent (3.4 billion lb) zinc, 0.73 percent (581...
There are good indications that large porphyry copper deposits may be found beyond the borders of the Pebble property held by Northern Dynasty Minerals Ltd. Quaterra Resources Inc. has cut a deal on Groundhog, one of the most promising of these prospects in this area of Southwest Alaska known for its world-class copper potential. “The Groundhog project offers the potential to discover a major deposit in an established porphyry belt,” said Quaterra Chairman and CEO Tom Pat...
Skeena Resources Ltd. April 20 published results from a preliminary economic assessment that investigates the potential of combined development of its Spectrum and GJ properties in the Golden Triangle of northwest British Columbia. The economic study calls for starting with a 10,000-metric-ton-per-day mine at the porphyry copper-gold Donnelly deposit on the GJ side of the project; ramping up to 20,000 metric tons per day in year six, when mining of the porphyry gold-copper Central zone deposit at Spectrum begins; and...
Auryn Resources Inc. April 20 reported that it has begun mobilizing fuel and supplies for an extensive summer exploration program at its Committee Bay gold project in Nunavut that includes 25,000 meters of drilling. In January, Goldcorp invested C$35 million in Auryn, giving the gold mining major a 12.5 percent stake in the exploration company. The 2017 program will include exploration of 12 newly identified targets across the 3,800-square-kilometer (1,500 square miles) Committee Bay property. Drilling will be focused within...
With winter programs winding down and summer efforts rapidly ramping up, it is becoming clear that 2017 will be a much more vigorous year for the Alaska mining industry than the 2013 to 2016 period. For example, my internal estimates are already pushing $75 million for exploration activity alone and a significant number of projects that have announced exploration plans have not yet announced budgets for 2017, so that number is likely to rise. Compare this to estimates of less...
Hecla Mining Company April 20 reported that its Greens Creek Mine produced 1.9 million ounces of silver and 14,022 oz of gold during the first quarter of this year. While this is down from the 2.5 million oz of silver and 15,891 oz of gold recovered at the Southeast Alaska operation during the first three months of 2016, it is higher than the company expected. This drop in metals production is primarily due to lower grades. Mill throughput at Greens Creek averaged about 2,190 tons per day during the first quarter of this...
Teck Resources Ltd. April 25 reported the Red Dog Mine in Northwest Alaska produced 102,500 metric tons of zinc during the first quarter, a six percent drop compared to the same period last year. The company attributed this drop to challenges of processing the higher grade but more complex ore from Qanaiyaq, the new pit at Red Dog. During the first quarter, ore from Qanaiyaq pit was introduced to supplement declining grade ore from the Aqqaluk pit, however, mill performance was adversely affected as these ores are...
