Duluth Metals Announces Twin Metals Frame-of-Reference for Bechtel Led Pre-Feasibility Study

TORONTO, March 21, 2012 /PRNewswire/ --

Duluth Metals Limited ("Duluth Metals") (TSX: DM) (TSX: DM.U) is pleased to announce that Twin Metals Minnesota LLC has instructed Bechtel Engineering to prepare the NI-43-101 Pre-Feasibility Study on the Twin Metals Project based on the following parameters:

• A vertically integrated mining complex;
• Large scale phased underground mine plan and development;
• Evaluating different scenarios respecting both on-site and off-site surface facility alternatives, including examining options in milling capacity up to approximately 80,000 tonnes/day through-put; and,
• A hydrometallurgical plant with a minimum capability of producing copper cathode, nickel hydroxide and a PGM concentrate.

Vern Baker, President of Duluth Metals, stated: "Bechtel and the other Pre-Feasibility Consultants are aggressively working to define a large integrated mining operation that respects the environmental and social values of Minnesotans and which will benefit the State of Minnesota for generations.  This project is being planned with the latest technologies in order to protect Minnesota's environment and will be a long-term economic engine for Northern Minnesota."

An initial pre-feasibility NI-43-101 Resource Estimate report on the consolidated resources of the Twin Metals Project is nearing completion by AMEC and is anticipated to be finalized by the end of April, 2012.  This report is going through final iterations as minor additions are incorporated into the geologic model.  This resource will be used for mine planning purposes in the pre-feasibility study.  This initial resource update will be followed up by a pre-feasibility resource report which will incorporate data from recent, current, and near future targeted drill programs.

A number of risk factors may cause actual results, level of activity, performance or outcomes of such exploration and/or mine development to be materially different from those expressed or implied by such forward-looking statements including, without limitation, whether such discoveries will result in commercially viable quantities of such mineralized materials, the possibility of changes to project parameters as plans continue to be refined, the ability to execute planned exploration and future drilling programs, possible variations of copper, nickel and PGM grade or recovery rates, the need for additional funding to continue exploration efforts, changes in general economic, market and business conditions, and those other risks set forth in Duluth Metals' most recent annual information form under the heading "Risk Factors" and in its other public filings.  Statements related to "reserves" and "resources" are deemed forward-looking statements as they involve the implied assessment, based on realistically assumed and justifiable technical and economic conditions, that an inventory of mineralization will become economically extractable.  Forward-looking statements are not guarantees of future performance and such information is inherently subject to known and unknown risks, uncertainties and other factors that are difficult to predict and may be beyond the control of Duluth Metals.  Although Duluth Metals has attempted to identify important risks and factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors and risks that cause actions, events or results not to be as anticipated, estimated or intended.  Consequently, undue reliance should not be placed on such forward-looking statements.
