Duluth Metals Highlights 153.5 feet of 0.767% Copper, 0.197% Nickel and 1.988 grams Total Precious Metals at Twin Metals Minnesota's Birch Lake Deposit
- Drill results of an additional 28 holes (BL11-01 to BL12-21) in the Birch Lake Deposit of Twin Metals Minnesota
- The 28 drill holes from the Birch Lake Deposit which are featured in this press release will be factored into the final pre-feasibility AMEC resource numbers due early December 2012; this is in addition to the 159 additional drill holes and 70 wedge offsets for the Maturi Deposit
- The final AMEC resource report will provide the basis for mine planning within the pre-feasibility study. Duluth Metals also expects the new estimate will confirm the extent and distribution of the higher grade portions of the deposit
TORONTO, Nov. 27, 2012 /PRNewswire/ - Duluth Metals Limited ("Duluth Metals") (TSX: DM) (TSX: DM.U) is pleased to announce assay results for 28 holes on the Birch Lake Deposit within the Twin Metals Minnesota Project in northeastern Minnesota. The Birch Lake Deposit is one of three mineral resources in close proximity to one another within the Twin Metals Minnesota Project, these being the Maturi, Birch Lake and Spruce Road Deposits. All of the holes have significant length intercepts continuing to indicate a higher grade platinum+palladium+gold (TPM) content within the Birch Lake resource relative to other resources in the project. These additional holes will be incorporated into the final resource estimate to be issued by AMEC in early December 2012.
"The addition of these holes to the Birch Lake database will provide the basis for a stronger estimate in the western part of the Twin Metals Minnesota Project. The Birch Lake resource provides potential flexibility in the project as it is geographically separate (5 miles) from Maturi, and shows a higher contribution to revenue from precious metals than some of the other sections in the project", stated Vern Baker, President of Duluth Metals.
Drilling highlights in the Birch Lake Deposit include:
- BL11-07-W1 returned a 153.5 foot intersection of 0.767% copper, 0.197% nickel, 3.0 g/t silver and 1.988 grams TPM (TPM = Platinum+Palladium+Gold) at a 0.5% Cu cut-off.
- BL11-05 returned a 67.5 foot intersection of 0.710% copper, 0.230% nickel, 2.5 g/t silver and 1.817 grams TPM at a 0.5% Cu cut-off.
- BL12-09 returned a 101.3 foot intersection of 0.862% copper, 0.273% nickel, 3.0 g/t silver and 1.237 grams TPM at a 0.5% Cu cut-off.
- BL12-10 returned a 53 foot intersection of 0.638% copper, 0.182% nickel, 2.3 g/t silver and 1.158 grams TPM at a 0.5% Cu cut-off.
A more detailed summary of the assay results for BL11-01 to BL12-21 as grouped by areas can be found in the table below. True thickness is estimated at about 90% of core length:

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 Birch Lake Drill Program, half core samples were 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.

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.
