  • Drill results of an additional 30 holes (MEX-379 to MEX 408) in the Maturi Deposit of Twin Metals Minnesota
  • Approximately 159 additional drill holes and 70 wedge offsets for the Maturi Deposit, including the 30 holes featured in this press release, will be factored into the final pre-feasibility AMEC resource numbers due later this month (November 2012)
  • The final pre-feasibility AMEC resource estimate report will confirm the extent and distribution  of the higher grade portions of the deposit the  presence of which is indicated by the current drill results

TORONTO, Nov. 9, 2012 /PRNewswire/ - Duluth Metals Limited ("Duluth Metals") (TSX: DM) (TSX: DM.U) is pleased to announce assay results for 30 additional holes, MEX-379 to 408, on the Maturi Deposit within the Twin Metals Minnesota Project in northeastern Minnesota. The majority of the holes have significant length intercepts that meet a 0.5% Cu cut-off criteria. These holes, distributed across the Maturi Resource, continue to indicate the ability to define a higher grade sub-set of the resource for early utilization. These additional holes will be incorporated into the final resource estimate to be issued by AMEC later this month (November 2012).

"These additional 30 holes will be factored into the final pre-feasibility AMEC resource study which we are expecting by the end of this month", stated Vern Baker, President of Duluth Metals. "The final pre-feasibility AMEC resource estimate will allow mine planning to focus on early utilization of the most economic mineralization. This resource estimate is expected to upgrade a significant portion of the resource from the Inferred to the Indicated category."

Drilling highlights in the western section of the Maturi Deposit include:

The Twin Metals Minnesota Project covers over 32,000 acres of land/mineral interests and consolidates the largest base and precious metal land position in Minnesota. This extensive land position provides Twin Metals with the platform to plan and develop one the world's largest copper-nickel-PGM deposits within a new emerging mining belt in Minnesota, USA.

For the 2011-2012 Drill Program, half core samples are being prepared at ALS Minerals laboratories in Thunder Bay and then shipped to its analytical facilities in Vancouver. Samples are being analyzed for Au, Pt, and Pd using a 30g standard fire assay with an ICP-AES finish and for 33 other elements using a four acid (near total) digestion and a combination of ICP-MS and ICP-AES. ICP over-limits for copper and nickel are re-analyzed using dissolution four acid (near total) digestion followed by ICP-AES or AAS. The remaining half core samples are being stored in Minnesota.

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. In addition, all forward-looking statements in this press release are given as of the date hereof.  Duluth Metals disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, save and except as may be required by applicable securities laws.  The forward-looking statements contained herein are expressly qualified by this disclaimer.
