NEW YORK Duluth Metals Ltd. has named Kelly Osborne interim vice president of project development for its Twin Metals Minnesota LLC copper-nickel-platinum project.
Osborne will oversee the Minnesota project until a permanent replacement can be found, Duluth chairman and chief executive officer Christopher Dundas told AMM. He will then resume his responsibilities as chief operating officer of Duluth.
A number of crucial decisions will be made during the prefeasibility study in the next three to six months, including the scale, ramp-up and whether to include downstream processing plants at the northeast Minnesota mine, Dundas said.
"This is one of the largest development projects in the world and the beauty of this is its in the U.S.," he said, noting that these projects are typically located in more "exotic" areas, which can be burdensome. "Its nice to have this right in the heart of North America."
Its too early to speculate on the type of downstream operations that might be included in the project, but the company is evaluating all of its options, Dundas said.
The prefeasibility study, initially set to be completed by mid-2013 (amm.com, May 22), has now been pushed back to the start of 2014 due to the vast size of the project, he told AMM.
Duluth last month raised its resource estimates for the Twin Metals project, a 60-40 joint venture between Toronto-based Duluth and Chilean miner Antofagasta Plc, to 13.6 billion pounds of copper, 4.4 billion pounds of nickel and a combined 21.4 million ounces of palladium, platinum and gold from a prior estimate of 8 billion pounds of copper, 2.5 billion pounds of nickel and 12.1 million ounces of palladium, platinum and gold combined (amm.com, June 13).
