New report confirms enormous potential of Duluth base metals/pgm/gold resource – by Lawrence Williams ( – 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.

‘Mining Truth initiative’ wants to ‘educate’ Minnesotans about mining – by Dorothy Kosich ( – 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.

Duluth sets Bechtel parameters for 100 year copper-nickel-pgm mine PFS – by Lawrence Williams ( – March22, 2012)

Duluth Metals’ huge copper-nickel-pgm-gold resource on the Duluth complex in northern Minnesota moves on a stage with top engineering company Bechtel being given the parameters on which to base a PFS

HONG KONG (Mineweb) –  Talking to Duluth Metals Chairman and CEO, Chris Dundas at Mines & Money Hong Kong he remains extremely enthusiastic about his monster mining project in Northern Minnesota, USA which, if and when it comes to fruition, will become one of the world’s great underground mining operations with a mine life probably well in excess of 100 years.

Top engineering company Bechtel has been retained to undertake the preparation of the NI 43-101 Prefeasibility Study (PFS) on the initial project based primarily on the Nokomis section of this vast resource and the parameters under which Bechtel has been instructed give a great indication of the scale of operations envisaged.

Bechtel has thus been instructed to prepare its study based on the following:
