U.S. Sen. Lisa Murkowski (R-Alaska) and Joe Manchin (D-West Virginia) have teamed up to introduce bipartisan legislation aimed at addressing America's "Achilles' heel" – a heavy dependence on foreign countries for its growing mineral needs. "Our nation's mineral security is a significant, urgent, and often ignored challenge. Our reliance on China and other nations for critical minerals costs us jobs, weakens our economic competitiveness, and leaves us at a geopolitical d...
As the Pebble Limited Partnership advances the Pebble copper-gold-molybdenum project through the permitting process, environmental groups opposed to the proposed mine are employing a wide arsenal of tactics to impede the progress. In its latest volley, Earthworks, an environmental non-governmental organization (ENGO), has requested that the British Columbia Securities Commission (BCSC) and the U.S. Securities and Exchange Commission (SEC) investigate whether Northern Dynasty...
With 12.5 million acres of land spanning Alaska's Interior, Doyon Ltd. is the largest private landholder in the state and one of the largest in the nation. For mining and mineral exploration companies, the rich mineral potential of these lands may be more impressive than the sheer size of the estate. This is because the Doyon region is a nearly Texas-sized swath of Interior Alaska that is renowned for its gold and a host of other metals, providing the regional corporation,...
As is usually the case this time of year, the mining industry is awash in backward-looking statements designed to allow for more accurate forward-looking statements. Prime among them is one of my favorites, S&P Global's annual "World Exploration Trends 2019", a summary of what happened industry-wide in 2018 and what it may portend for the mining industry in 2019. The study predicts that global exploration budgets will increase again in 2019, although by a smaller amount, with...
The value of non-fuel metals produced in Alaska and the United States during 2018 were similar to 2017, according to Mineral Commodity Summaries 2019, an annual report published by the U.S. Geological Survey. Alaska mines produced roughly $3.44 billion worth of non-fuel minerals last year, down nearly 3 percent from the US$3.53 million in 2017. This slight drop is largely due to lower output from the two largest mines in the state – Fort Knox and Pogo. The roughly 1.4 b...
Freegold Ventures Ltd. March 5 reported that the potentially large porphyry copper-gold-silver-tungsten deposits it has been exploring on the Shorty Creek project in Interior Alaska has drawn the interest of Australia-based South32 Ltd. Under an option agreement with Freegold Ventures, a South32 subsidiary has agreed to fund up to US$10 million of exploration over the next four years, including US$2 million this year. This exploration spending keeps an option open for South32...
Northern Cobalt Ltd. Feb. 26 reported that a recently completed magnetic survey has confirmed the presence of a large magnetite body at its Snettisham vanadium-titanium project in Southeast Alaska. Situated about 50 kilometers (32 miles) south of Juneau, Snettisham hosts a large outcropping body of magnetite with iron, titanium, vanadium, and possibly platinum-group elements. This intrusion extends for at least 3,800 meters along the coast of the Snettisham Peninsula and up...
Pebble Limited Partnership has taken another step toward gaining the permits needed to develop a mine at its large copper-gold-molybdenum project in Southwest Alaska. On Feb. 20, the U.S. Army Corps of Engineers – Alaska District announced that it has published the draft environmental impact statement for a proposed 20-year mine at this world-class deposit that could help fill the United States' increasing need for copper, a demand that is being driven by the expanding e...
U.S. Sen. Lisa Murkowski, R-Alaska, called on Congress to pass legislation that will curb the United States' increasing dependence on foreign countries for its growing mineral needs. In its Mineral Commodity Summaries 2018, the U.S. Geological Survey identified 50 minerals for which the U.S. was reliant on other countries for at least 50 percent of its supply, including 21 for which America is 100 percent import reliant. Many of these are on the USGS list of 35 minerals and...
In addition to being a past producer and a future source of most of the 35 minerals and metals considered critical to the United States, Alaska currently contributes a globally significant amount of one of these vital metals – germanium. While not a widely known metal, germanium has optical qualities that make it an important ingredient in fiber-optics, infrared optics, electronics and solar energy systems. "The extensive use of germanium for military and commercial a...
Ucore Rare Metals Inc. Nov. 6 said it has begun consultation with officials from the Ketchikan Gateway Borough, the Southeast Alaska municipality where Ucore plans to build its Strategic Metals Complex, a facility that will produce individual rare earth elements and other strategic metals from non-Chinese sources. Rare earth elements are more abundant than their name suggests. The 17 elements commonly included in this group – 15 lanthanide elements on the periodic table, p...
With nearly indistinguishable physical and chemical properties, niobium and tantalum are almost always found together in nature. Both are also critical to the defense, energy and high-tech sectors in the United States, but neither are mined domestically. For these reasons, the United States Geological Survey considers these transition metals "indispensable twins" that are critical to America's economic and strategic wellbeing. "Niobium and tantalum are transition metals that...
Ucore Rare Metals Inc. Nov. 7 said it plans to exercise its option to purchase IBC Advanced Technologies Inc., the Utah-based company that developed the molecular recognition technology used to separate rare earth elements from a solution derived from Ucore's Bokan Mountain project in Southeast Alaska. This technology, also known as MRT, was proven to efficiently pull out individual high-purity rare earths with a pilot plant known as SuperLig-One and is being implemented into...
Geologists familiar with Alaska already know the Far North State is a great place to explore for critical minerals and metals such as graphite, rare earths, platinum metals, cobalt and tin. A new report published by the U.S. Geological Survey, however, indicates that Alaska may be richer in these and other minerals and metals vital to the economy and security of the United States than previously realized. Working alongside the Alaska Division of Geological & Geophysical...
U.S. President Donald Trump sparked a renewed interest in critical minerals and metals when he issued an executive order calling on federal agencies to devise a strategy to ensure the United States has reliable supplies of these commodities vital to America's economic and strategic security. "It shall be the policy of the federal government to reduce the nation's vulnerability to disruptions in the supply of critical minerals, which constitutes a strategic vulnerability for...
Alaska is rich in rare earth, a unique group of elements that are so distinctive that most are placed in their own separate section at the bottom of the periodic table. While scientist have long realized that rare earths possessed distinctive characteristics that set them apart from their fellow elements, it wasn't until the advent of the color television in the 1960s that these unique properties had any sort of widespread practical application. Over the ensuing five decades,...
With nearly indistinguishable characteristics, niobium and tantalum are considered the "indispensable twins" among the 35 minerals and metals considered critical to the United States. "Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties," the U.S. Geological Survey wrote in a 2018 paper on the twin metals. While nearly identical twins, they each have their own set of unique...
While copper is not on the United States Geological Survey's list of 35 minerals and metals critical to America, there is no doubt of this metal's importance to both the everyday and avant-garde technologies vital to America's economy and security. "None of the other critical minerals work without copper," Trilogy Metals President and CEO Rick Van Nieuwenhuyse told Mining News. Automobiles are a prime example of how emerging technologies and green energy will drive the demand...
With a melting point of 5,756 degrees Fahrenheit and a heat-stable crystalline structure, rhenium is extremely resistant to both heat and wear. This durability makes it a vital element in superalloys used in jet and industrial gas turbine engines. "The high-temperature properties of rhenium allow turbine engines to be designed with finer tolerances and operate at temperatures higher than those of engines constructed with other materials," the United States Geological Survey...
The strength and durability of steel and other alloys is greatly enhanced by adding a small amount of vanadium, currently the primary use of this critical mineral. While this toughness is legendary, the future of vanadium could rest in another set of more subtle traits that could make it the element of choice for large-scale storage of renewable energy generated by wind and solar. "Vanadium is becoming more widely used in green technology applications, especially in battery...
With more than 100 known tin occurrences, Alaska is considered the best place in America to establish a domestic source of this critical alloy metal that has defined human progress since the dawn of the Bronze Age. "Today, Alaskan tin deposits are known to be widespread, occurring from the central Alaska Range north to the Brooks Range and across Interior Alaska ... Southwest Alaska and the Seward Peninsula," according to the 1997 publication, Mineral Deposits of Alaska. And...
Since the stampedes of prospectors trekked North in the latter half of the 19th Century, the lure of Alaska's rich gold lodes has drawn dreamers and miners North. Today, four hardrock mines and hundreds of family-run placer operations across the Last Frontier churn out roughly 1 million ounces of this alluring precious metal each year – and the largest stores of aurum discovered here have yet to be realized. Despite being a relatively rare metal that has served as a c...
Antimony is a poor conductor of heat, an attribute that lends itself to this semi-metal's most common use, as an ingredient to make clothing, mattresses and other products flame resistant. While making work clothes and household items safer and less likely to catch fire is a relatively new use for antimony, humans have been using antimony for other purposes for more than 5,000 years. "For example, the ancient Egyptians and early Hindus used stibnite, which is the major ore...
Extremely rare, yet a vital ingredient to emerging solar panel technologies, tellurium is the epitome of what it means to be a critical metalloid, an element that possesses the properties of both a metal and non-metal. "Most rocks contain an average of about 3 parts per billion tellurium, making it rarer than the rare earth elements and eight times less abundant than gold," the United States Geological Survey wrote in a 2015 report on this critical metalloid. "Grains of...
Extremely hard and with the highest melting point of all the elements on the periodic table, tungsten is vital to a broad spectrum of commercial and military applications, yet there are no mines in the United States producing this durable metal. Nearly 60 percent of the tungsten consumed in the U.S. during 2018 was used to make the cemented tungsten-carbide, a compound of roughly equal parts tungsten and carbon. Roughly twice as strong as steel, tungsten carbide is often...
