Duluth Metals Highlights 155 feet of 1.371% Copper, 0.281% Nickel and 0.863 grams Total Precious Metals at west Maturi in the Twin Metals Minnesota Project

11.10.2012  |  CNW
  • Drill results of additional 30 holes in the Maturi Deposit of Twin Metals Minnesota
  • Drilling of the Maturi Deposit consistently returned good grades and intersections across four areas within the deposit
  • Approximately 170 additional drill holes, including the 30 holes (MEX-349 to MEX 378) featured in this press release, will be factored into the final pre-feasibility AMEC resource study due in Fall 2012
  • The final pre-feasibility AMEC resource estimate report will confirm the economic opportunities represented by this resource

TORONTO, Oct. 11, 2012 /CNW/ - Duluth Metals Limited ("Duluth Metals") (TSX: DM) (TSX: DM.U) is pleased to announce assay results for 30 additional holes from Maturi as drilling continues on the Twin Metals Minnesota Project in northeastern Minnesota. Drilling results continue to indicate continuous and relatively thick mineralization with certain higher grade zones. These recently completed holes will be incorporated into the final resource estimate to be issued by AMEC in Fall 2012.

All of the 30 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. The holes are grouped into four distinct areas within the resource as shown in Figure 1 further in this press release, and are referred to as:

  1. Area 1 - shallow west Maturi
  2. Area 2 - deeper west Maturi
  3. Area 3 - central Maturi
  4. Area 4 - northeast Maturi

"This set of 30 holes highlights the continuity of this resource as well as the significant thickness of the well mineralized material", stated Vern Baker, President of Duluth Metals. "The ability to include data from a large number of additional holes and to incorporate a more detailed geological interpretation will provide a much stronger resource estimate for the Twin Metals Minnesota project this fall. The final pre-feasibility AMEC resource estimate will allow mine planning to focus on early utilization of the most economic mineralization. This resource estimate will also upgrade large areas of the resource from the Inferred to the Indicated category."

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

In Area 1 (shallow west Maturi):

  • Mex-371 returned a 155 foot intersection of 1.371% copper, 0.281% nickel, 5.1 g/t silver and 0.863 grams TPM (TPM = Platinum+Palladium+Gold) at a 0.5% Cu cut-off.

In Area 2 (deeper west Maturi):

  • Mex-373 returned a 105 foot intersection of 0.868% copper, 0.262% nickel, 3.3 g/t silver and 0.743 grams TPM at a 0.5% Cu cut-off.
  • Mex-357 returned a 144 foot intersection of 0.799% copper, 0.292% nickel, 2.8 g/t silver and 0..704 grams TPM at a 0.5% Cu cut-off.

In Area 3 (central Maturi):

  • Mex-351 returned a 62 foot intersection of 0.823% copper, 0.278% nickel, 2.7 g/t silver and 1.028 grams TPM (TPM = Platinum+Palladium+Gold) at a 0.5% Cu cut-off.
  • Mex-362 returned a 85 foot intersection of 0.805% copper, 0.264% nickel, 2.8 g/t silver and 0.905 grams TPM at a 0.5% Cu cut-off.
  • Mex-367 returned a 147 foot intersection of 0.758% copper, 0.231% nickel, 3.0 g/t silver and 0.813 grams TPM at a 0.5% Cu cut-off.

In Area 4 (northeast Maturi):

  • Mex-355 returned a 158 foot intersection of 0.905% copper, 0.306% nickel, 3.1 g/t silver and 0.782 grams TPM (TPM = Platinum+Palladium+Gold) at a 0.5% Cu cut-off.
  • Mex-376 returned a 90 foot intersection of 0.870% copper, 0.255% nickel, 2.9 g/t silver and 0.771 grams TPM at a 0.5% Cu cut-off.

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.

Phillip Larson, P. Geo. is the Qualified Person for Duluth Metals and Senior Geologist for Duluth Metals, in accordance with NI 43-101 of the Canadian Securities Administrators, and is responsible for Duluth Metals technical content of this press release and quality assurance of the exploration data and analytical results.

About Duluth Metals Limited

Twin Metals holds mineral and land assets of approximately 32,000 acres of leased and permitted land, including mineral resources prepared in compliance with the requirements of NI 43-101.

This press release contains forward-looking statements (including "forward-looking information" within the meaning of applicable Canadian securities legislation and "forward-looking statements" within the meaning of the US Private Securities Litigation Reform Act of 1995) relating to, among other things, the results of drilling operations of Duluth Metals and exploration and mine development.  Generally, forward-looking statements can be identified by the use of words such as "plans", "expects" or "does not expect", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates" or "does not anticipate", or "believes", or variations of such words and phrases or statements that certain actions, events or results "may", "could", "would", "might" or "will be taken", "occur" or "be achieved".  Duluth Metals has relied on a number of assumptions and estimates in making such forward-looking statements, including, without limitation, the prices of copper, nickel and platinum group metals (PGMs) and the costs associated with continuing exploration and mining development.  Such assumptions and estimates are made in light of the trends and conditions that are considered to be relevant and reasonable based on information available and the circumstances existing at this time. 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.
