Straightforward and low-cost ore sorting and jig circuits could produce 20% copper concentrates. Recent testing has demonstrated that a simple and inexpensive two-step process could elevate the high-grade copper mineralization that American West Metals Ltd. has outlined in near-surface deposits at its Storm project in Nunavut into a high-quality direct shipping ore (DSO) ready for market. "The program has produced commercial grade DSO products from typical copper ores through...
American West Metals Ltd. capped its first season of exploration drilling in Nunavut with the discovery of substantial copper mineralization at depth at Storm Copper, a development that the explorer believes will be a "game-changer" for the early-stage project. Initial assays from drill hole ST22-10 confirm the presence of sediment-hosted copper and zinc sulfide mineralization that indicates the potential for a major mineralized system lying below the very high-grade copper...
"Grade is king" is an adage that guides mineral exploration and mining. The premise behind this basic axiom of the mining business is the less ore that needs to be mined and processed per ounce of precious metals, pound of base metals, kilogram of critical minerals, or carat of gemstones produced, the more profitable an operation will be. The kingliest of orebodies would be of such high grade that a mining company would simply need to dig up the ore, crush it, and then ship it...
American West Metals Ltd., a junior led by two mining industry veterans from Australia, has returned to the Arctic this year for a second field season in pursuit of rich deposits at the Storm Copper project on Somerset Island in northeastern Nunavut. Storm hosts a 120-kilometer (75 miles) mineralized trend within an extensive 4,145-square-kilometer (1,600 square miles) land package that covers multiple copper and zinc geochemical anomalies along strike. In March 2021,...
Osisko Metals Inc. May 8 said that recent tests show that ore sorting shows the potential to reduce the costs to transport and process ore at a future mine at its Pine Point zinc project in Northwest Territories. Ore sorting, which identifies and rejects unmineralized rock prior to feeding ore into a mill, is gaining popularity as a means to improve ore grades and reduce processing costs at mines. Osisko sent 800 kilograms (0.8 metric tons) of mineralized samples from Pine Poi...
Trilogy Metals Inc. Jan. 31 announced a US$16.2 million work program this year for the Upper Kobuk Mineral Projects in Northwest Alaska, a work program that is expected to result in major milestones toward realizing the world-class mineral potential the Ambler Mining District has to offer. Similar to the previous two years, Australia-based South32 Ltd. will invest US$9.2 million of the 2019 funding, which will go toward infill and resource expansion drilling at the Bornite...
With initial results from the 2018 drilling at Bornite topping 5 percent copper, Trilogy Metals Inc. and South32 Ltd. have decided to extend this year's program at the Upper Kobuk Mineral Projects in the Ambler Mining District of Northwest Alaska. Trilogy has only received partial assay results from one hole drilled this year, but the results are impressive. This hole, RC18-0247, cut 16.4 meters grading 5.34 percent copper and 0.21 percent cobalt to the north of the...
