Mining on the environmentally sensitive Duluth Metallurgical complex in Minnesota is gleaning strong local support from a union/Chamber of Commerce alliance.

LONDON – In what must be a welcome development for prospective miners, PolyMet and Duluth Metals, Minnesota’s Chamber of Commerce and local mining unions will be mounting a combined campaign to try to ensure that mining of what has to be one of the world’s most significant mineral deposits, is given the go-ahead by state and federal bodies.

According to a report in the Duluth News Tribune, The Minnesota Chamber of Commerce, the state’s largest business group, and the Minnesota Building and Construction Trades Council have formed “Jobs for Minnesotans” to promote development of the state’s first-ever massive base and precious metals mining operations on the Duluth Metallurgical Complex which hosts one of the world’s largest potential polymetallic orebodies and which could see large scale mining for the next century, with its associated employment and tax benefits for the state and federal economies.

The Duluth Complex hosts an enormous resource of relatively low grade polymetallic mineralisation, which in combination represents perhaps the world’s largest ever discovery of an orebody containing copper, nickel, cobalt, pgms and gold – and Polymet and the Duluth Metals 60:40 jv with Antofagasta – the Twin Metals project – are the two most advanced projects on the Complex at the moment. However the area where these enormous deposits is hosted lies in an environmentally sensitive locality between the Boundary Waters recreational area and brownfields mining and processing sites left over from the still significant Minnesota taconite iron ore mines and process plants.

Insolvent US coal miner agrees to stop mountaintop-removal mining – by Henry Lazenby (MiningWeekly.com – November 15, 2012)

TORONTO (miningweekly.com) – Bankrupt US coal miner Patriot Coal on Thursday became the first miner to cease large-scale mountaintop-removal coal mining in central Appalachia in exchange for more time to comply with the Clean Water Act at several of its central Appalachian mines.

As the company is preparing for Chapter 11 litigation, it had reached an agreement with three environmental groups that had sued over water pollution from its West Virginia operations.

The agreement was presented for consideration to Judge Robert Chambers of the US District Court for the Southern District of West Virginia, and had its roots in water pollution lawsuits filed by environmental protection groups the Sierra Club, the Ohio Valley Environmental Coalition (OVEC) and West Virginia Highlands Conservancy.

Mountaintop-removal coal mining is an economical but devastating form of strip mining unique to West Virginia, Virginia, Kentucky and Tennessee. Coal companies blast apart mountain ridge tops to expose multiple coal seams and then dump the waste in streams, creating so-called valley fills.

Patriot Coal said it had concluded that continuing and expanding its surface mining, particularly large-scale surface mining of the type common in central Appalachia, was not in its long-term interests.

More mineral riches from the smoky waters of Minnesota – by John Chadwick (International Mining – November 2012)

June 19, 2013November 14, 2012

International Mining is a global technical magazine written for miners by miners. John Chadwick is the publisher. john@im-mining.com

Ore riches that built America have much more to offer. Minnesota’s Iron Ranges to the west of Lake Superior – Vermilion, Mesabi and Cuyuna from the northeast of Duluth down to the south-southwest – have been the most important ore deposits in US history, and continue to be so, providing well over 90% of the iron ore the country needs. Just a few of the great historical landmarks include the establishment, in 1901, of the world’s first multi-billion dollar corporation, US Steel.

There was also the Minnesota Mining and Manufacturing Co (3M) founded in 1902 at the Lake Superior town of Two Harbors. However its only connection with the Iron Ranges was location. The deposit was set up to mine for grinding-wheel abrasives proved to be of little value.

William Boeing made profits from the Mesabi Range and just a few other great names with Iron Ranges associations include Henry Bessemer, Frederick Weyerhaeuser, Andrew Carnegie, John D. Rockefeller, Kelsey D. Chase, and J.P. Morgan.

According to the miner, truly magnificent orebodies are being revealed in an area that has already played a very important role in the US mining industry.

LONDON (INTERNATIONAL MINING) – Ore riches that built America have much more to offer. Minnesota’s Iron Ranges to the west of Lake Superior – Vermilion, Mesabi and Cuyuna from the northeast of Duluth down to the south-southwest – have been the most important ore deposits in US history, and continue to be so, providing well over 90% of the iron ore the country needs. Just a few of the great historical landmarks include the establishment, in 1901, of the world’s first multi-billion dollar corporation, US Steel.

Before that, in May 1890, Edmund Longyear (founder of one of the companies that was to become, much later, Boart Longyear) brought the diamond drill to the Iron Ranges. This exploration tool was to be a key to unlocking the riches of the region.
William Boeing made profits from the Mesabi Range and just a few other great names with Iron Ranges associations include Henry Bessemer, Frederick Weyerhaeuser, Andrew Carnegie, John D. Rockefeller, Kelsey D. Chase, and J.P. Morgan.

Of the known US mineral resources, Minnesota accounts for 99% of the nickel, 90% of the iron, 88% of the cobalt, 51% of the platinum and 48% of the palladium, 40% of the manganese and 34% of the copper. America’s third largest mining state may be poised to take the lead. In work pioneered by Duluth Metals, its Senior Vice President, Exploration, Dean M. Peterson and his innovative team, truly magnificent orebodies are being revealed in an area that has already played such an important role in the US mining industry.

China joins nations seeking treasure in warming Arctic – by Elisabeth Rosenthal (New York Times/NBC News – September 19, 2012)

Bid to join Arctic Council is so ‘it won’t be shut out from decisions on minerals and shipping,’ expert says

NUUK, Greenland — With Arctic ice melting at record pace, the world’s superpowers are increasingly jockeying for political influence and economic position in outposts like this one, previously regarded as barren wastelands.

At stake are the Arctic’s abundant supplies of oil, gas and minerals that are, thanks to climate change, becoming newly accessible along with increasingly navigable polar shipping shortcuts. This year, China has become a far more aggressive player in this frigid field, experts say, provoking alarm among Western powers.

While the United States, Russia and several nations of the European Union have Arctic territory, China has none, and as a result, has been deploying its wealth and diplomatic clout to secure toeholds in the region.

“The Arctic has risen rapidly on China’s foreign policy agenda in the past two years,” said Linda Jakobson, East Asia program director at the Lowy Institute for International Policy in Sydney, Australia. So, she said, the Chinese are exploring “how they could get involved.”

Endangered species listing for Sage grouse would be crippling for the country – by Dorothy Kosich (Mineweb.com – September 10, 2012)

An endangered species listing for the western sage grouse is “a horrible, mean and nasty law and we don’t want to go there,” says the director of the Wyoming Wildlife and Natural Resource Trust.

LAKE TAHOE, NEVADA (MINEWEB) – “The entire country could be crippled immensely” if 11 western states fail in their efforts to avert a federal Endangered Species Act (ESA) listing for the sage grouse,” warned Bob Budd, executive director of the Wyoming Wildlife and Natural Resources Trust, an independent state agency aimed at enhancing wildlife habitat and natural resource values throughout Wyoming.

In a recent speech to the Nevada Mining Association Convention at Stateline, Lake Tahoe, Budd stressed that although western sage grouse populations have experienced a significant decline in the past 50 years, “The last place we want sage grouse being managed is in the federal courts.”

If the bird is listed under the ESA in 2015, individual birds rather than sage grouse populations will be protected by the federal government, Budd observed.

The Doer [Robert Friedland – Mining Entrepreneur] – by Peter Koven (National Post – September 4, 2012)

September 4, 2012

The National Post is Canada’s second largest national paper.

On paper, Robert Friedland’s influence on the Canadian mining world seems to be waning. The legendary promoter showed a rare sign of weakness this year, losing control of Ivanhoe Mines and its massive Oyu Tolgoi copper mine in Mongolia to British-Australian mining giant Rio Tinto, and Friedland has seemingly disappeared from public view. So why can’t people stop talking about him?

Because love him or hate him, there’s no disputing Friedland’s imprint on the industry. From mastering the art of mining stock promotion in the 1980s and 1990s, to correctly calling the China boom and forging business ties with Asia in the 1990s and early 2000s, Friedland has always been the trailblazer everyone else tries to follow. In the few months the self-made billionaire has spent out of the limelight, investors have speculated wildly about when and where he will pop up next. Such speculation has never been easy where Friedland is concerned.

After a stint as a hippie in the 1970s, during which he befriended Steve Jobs, Friedland embraced the junior mining world and set up shop in Vancouver. He has rarely strayed from the headlines in the years since. He developed a big gold mine in Colorado, which was later shut down after an environmental accident (earning Friedland the “Toxic Bob” nickname that still sticks).

Mining heritage still alive in Upper Peninsula [Michigan] – by Phil Power (Holland Sentinel – August 20, 2012)

August 20, 2012

http://www.hollandsentinel.com/homepage

Ann Arbor — Michigan’s Upper Peninsula has been a powerfully mining-oriented place ever since early explorers were astonished to discover enormous chunks of pure copper in the Keweenaw Peninsula.

The iron ore deposits uncovered west of Marquette in the 19th century were so rich that unprocessed ore was shipped directly to blast furnaces to be made into iron. Once those deposits were worked out, vast quantities remained of less pure — but plenty rich — iron ore. Ever since, this has been one of the U.P.’s biggest industries, creating jobs extracting, processing and shipping iron ore to steel mills from Cleveland to Gary, Ind.

I’ve just returned from a family vacation at our cabin “up north,” where we toured the Tilden iron mine near Negaunee, owned and operated by Cliffs Natural Resources Co., which readers may remember was named Cleveland-Cliffs until a few years ago.

The scope and scale of the mine flabbergasted us. As we approached, we saw a vast three-story rust-colored building looming that seemed to run on for a mile or so. Hills of waste tailings as high as the biggest ski hill rose up to the south.

SEC conflict minerals rule foot-dragging a nightmare-GAO – by Dorothy Kosich (Mineweb.com – July 24, 2012)

The longer the SEC delays adoption of a final conflict minerals rule, the worse the situation becomes for global manufacturers voluntarily trying to keep conflict minerals out of supply chains.

RENO (MINEWEB) – A performance audit by the U.S. General Accounting Office (GAO) has found the continued delay of the SEC to issue a final conflict minerals rule has contributed to “a lingering uncertainty among industry and other stakeholders” who have tried to implement voluntary conflict minerals supply chain initiatives.

In a recent report to the U.S. Congress, the GAO noted “the uncertainty regarding SEC’s reporting and due diligence requirements” has complicated the efforts of industry associations, multilateral organizations, and others who have developed global and in-region sourcing initiatives to help companies comply with future rules regarding conflict minerals.

Congress has pressured the SEC on two fronts to adopt rules relating to conflict minerals and resource extraction. In a June 22 letter to the SEC, 58 members of Congress urged the commission to implement Sections 1502 and 1504 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, which require public companies to make disclosures relating to the use of conflict minerals and payments made for mining of resources.

Mining Boom in Great Lakes States Prompts Environmental Concern – by Jim Malewitz (Stateline/Pew Centre – May 24, 2012)

BIG BAY, Michigan – For thousands of years, the Salmon Trout River held fast to a deep secret, as its pristine waters flowed into Lake Superior. Below the river’s headwaters, and hidden underneath 1,000 feet of sand, clay and rock, lie 4.1 million metric tons of ore speckled with valuable metals — primarily nickel and copper — a deposit that’s valued at as much as $5 billion.

The treasure is no longer a secret here on the Yellow Dog Plains, a region of Michigan’s Western Upper Peninsula marked by large swaths of untouched lands. The staccato of the hydraulic drill now overpowers the sound made by birds flying overhead, and trucks kick up dust where trees once stood. “I see something new every time I come here,” says Catherine Parker, noting a yellow electrical cord stretching across the ground, seemingly without end. The winding dirt road she drives is now bordered by a path of utility lines recently installed. It’s an addition that Parker, who doesn’t own a cell phone, says ruins the aesthetic.

Kennecott Minerals, a local subsidiary of the London-based mining giant, Rio Tinto, discovered the deposit about a decade ago. The company, which owns at least 400,000 of acres of mineral rights on the peninsula, is nearing completion of the nearly $500 million Eagle Mine, set to become the first primary nickel mine in the United States.

[Duluth Metals Ltd.] Company boosts projections for mine near Ely, Minnesota – by Associated Press (Canadian Business Magazine – June 13, 2012)

June 19, 2013June 14, 2012

Founded in 1928, Canadian Business is the longest-publishing business magazine in Canada.

MINNEAPOLIS (AP) — New data suggest that a proposed mine near Ely contains one of the world’s largest deposits of copper, nickel and precious metals, along with some of the largest platinum and palladium resources outside South Africa, the company planning the mine told analysts Wednesday.

Duluth Metals Ltd., the Canadian-based parent of Twin Metals Minnesota LLC, significantly boosted its estimates of what could be pulled from the mine based on the data projections, which are measured two ways.

The company said the site has “indicated resources” of 8 billion pounds of copper, 2.5 billion pounds of nickel and 12.1 million ounces of palladium, platinum and gold. The company is highly confident in those estimates because they are based on samples taken from a high number of drill sites.

Duluth Metals separately projects “inferred resources” of 13.5 billion pounds of copper, 4.6 billion pounds of nickel and 15.8 million ounces of precious metals. Those estimates are less certain because they’re based on fewer bore holes.

[Minnesota] Ely copper deposit estimate doubles – by John Myers (Duluth News Tribune – June 14, 2012)

http://www.duluthnewstribune.com/

Already reported as the world’s largest untapped deposit of copper, the Twin Metals mine exploration area near Ely contains even more copper, nickel, platinum and other valuable metals than previously estimated, the mine’s parent company said Wednesday.

Toronto-based Duluth Metals released an updated resource estimate that’s double its 2009 estimate, though the new findings aren’t likely to change the already developing plans for Twin Metals mining operations.

Data gathered from exploratory drill sites, including 170 new drill core samples reviewed in the past nine months, indicate a staggering 8 billion pounds of copper, 2.5 billion pounds of nickel and 12 million ounces of palladium, platinum and gold underground at the site along Highway 1 near the Kawishiwi River.

New report confirms enormous potential of Duluth base metals/pgm/gold resource – by Lawrence Williams (Mineweb.com – June 14, 2012)

A new independent technical report from AMEC confirms the vast tonnages and economic grades in the Duluth Metals/Antofagasta Twin Metals base and precious metals project in Minnesota.

LONDON (MINEWEB) – We have always been very aware of the enormous potential of the ground held by Duluth Metals in eastern Minnesota on the edge of the old iron range which contains literally many billions of tons of complex ore grade material with significant copper, nickel, platinum group metals and gold content.

It has to be one of the world’s great mineral deposits – the major problems are permitting and finding the funding to mine it – neither necessarily an easy task nowadays, although one suspects the funding may be the easier of the two given that Duluth has brought in a base metals mining major, Antofagasta, to help it develop and mine a significant part of the resource under the Twin Metals jv (60% Duluth and 40% Antofagasta) banner.

On the permitting front there is bound to be considerable opposition to mine development there from environmentalists given it borders on the Boundary Waters recreational area. However Twin Metals reckons it can meet the environmentalists’ concerns using modern mining standards, mining the deposit underground to reduce the surface impact and use brownfield sites from old iron range operations to locate some of the key surface facilities.

Homestake [South Dakota gold mine] grand dame’s body donated to science – by Dorothy Kosich (Mineweb.com – May 31, 2012)

One of the ultimate examples of the sustainability of mines-the nation’s first deep underground science lab-was formally unveiled deep in the caverns of the former Homestake gold mine.

RENO (MINEWEB) – Nearly five years ago Mineweb told readers about plans to transform the former grand dame of U.S. gold mining, the Homestake gold mine in Lead, South Dakota, into the nation’s first national deep underground science laboratory.

On Wednesday, South Dakota’s Sanford Underground Research facility formally unveiled the new 4,850-foot deep Davis campus, which will seek to unravel the mystery of dark matter, and also search for a rare form of radioactive decay.

The Large Underground Xenon Dark Matter Search Experiment or LUX experiment, considered the world’s most sensitive and largest dark-matter detector–is the culmination of the work of 70 scientists and 14 institutions over the past four years.

LUX physicist Simon Fiorucci told a local TV station, “There is a lot of mass that does not emit light that we cannot account for.”

‘Mining Truth initiative’ wants to ‘educate’ Minnesotans about mining – by Dorothy Kosich (Mineweb.com – May 24, 2012)

Minnesota environmental special interests say their latest initiative aims to engage all Minnesotans, including miners, “in a respectful, open, fact based dialogue” about sulfide mining.

RENO (MINEWEB) – A coalition of three environmental organizations Wednesday announced it has launched a statewide sulfide mining initiative in Minnesota. Two mining companies, PolyMet and Twin Metals, are developing two mines in Minnesota’s lake country.

“Today, there is little awareness about sulfide mining-it’s very different from the iron ore mining that is more familiar to Minnesotans,” said Paul Danicic, executive director of Friends of the Boundary Waters Wilderness and founding member of the initiative Mining Truth. “This is a complex issue with long-term economic and environmental implications. We need a broad conversation about this.”

“The evidence shows there is reason to be cautious about effects on our lakes, rivers and groundwater, but we also recognize that the immediate need for jobs in Northern Minnesota is real,” said Paul Austin, executive director of Conservation Minnesota and founding member of Mining Truth.
