Re: News Releases - Friday, December 11, 2009 Title: Duluth Metals Receives NI 43-101 Report and Updated Resource Estimate for the Nokomis Deposit
TORONTO, Ontario, December 11, 2009 -- Duluth Metals Limited ("Duluth") (TSX: DM) (TSX:DM.U) today announces the receipt of an independent NI 43-101 compliant report completed by Scott Wilson Roscoe Postle Associates Inc. (Scott Wilson RPA) entitled "Technical Report on the Resource Estimate for the Nokomis Deposit on the Nokomis Property, Minnesota, USA". The report, which has been filed on SEDAR (www.sedar.com), updates the previous NI 43-101 compliant resource estimate and defines six higher-grade areas within this expanded resource. These higher-grade areas will be the focus of future mine planning, including any potential early sequencing that could improve the payback of the capital investment.
The six higher-grade areas are all contained within the current mineral resource. The three highest grade areas (Western, Eastern and Central) have a cumulative total of 92 million tonnes of Indicated Resources at an average grade of 1.80 CuEq%(copper equivalent grade) using a 1.0% CuEq cut-off grade. In addition, these three areas contain a combined 22 million tonnes of Inferred Resources at an average grade of 1.81 CuEq%, also using a 1.0% CuEq cut-off grade. The other higher grade areas (A, B and C) have a combined total of approximately 48 million tonnes of Indicated Resources at an average grade of 1.75% CuEq using a 1.0% CuEq cutoff grade and an additional 12 million tonnes of Inferred Resources at an average grade of 1.68% CuEq using a 1.0% CuEq cutoff grade. Together, the six higher-grade areas total approximately140 million tonnes of Indicated Resources and an additional 34 million tonnes of Inferred Resources. These totals are significant in relation to the projected 14 million tonnes per year (40,000 tonnes per day) of annual throughput contemplated in the Scott Wilson RPA NI 43-101 Preliminary Assessment dated January 2009.
The six higher-grade areas are shown in the Figure below which can also be viewed at www.duluthmetals.com by navigating to this press release.
Christopher Moreton, Ph.D., P.Geo. and Richard Routledge M.Sc., P.Geo, both of Scott Wilson RPA, Toronto Canada, are the Independent Qualified Persons who prepared the report which is available on both SEDAR and on the Company website (www.duluthmetals.com). A previous press release (October 26, 2009) also summarised these results.
"This new Resource Report prepared by Scott Wilson RPA confirms Nokomis as one of the largest valuable mineral assets in the world" stated Henry J. Sandri, President and CEO. "We look forward to entering 2010 with a strong program to move this deposit forward towards production. We will certainly be focusing on the potential expansion and mine sequencing of the higher grade zones which will be studied carefully during pre-feasibility in order to enhance and optimize cash flow in the initial years of operation"
The Scott Wilson RPA report states that the updated Nokomis Resource Estimate now contains 550 million tonnes of Indicated Resources grading 0.639% copper, 0.200% nickel, 0.660 grams per tonne TPM (TPM = Pt + Pd + Au) for a CuEq grade of 1.51%, plus an additional 274 million tonnes of Inferred Resources grading 0.632% copper, 0.207% nickel, 0.685 grams per tonne TPM for a CuEq grade of 1.53% (see Table footnotes further in this press release for an explanation of the copper equivalent formula).
The Scott Wilson RPA report provides a detailed summary of the Resource Estimate, at various cut-off grades, as follows:

- CIM definitions were followed for Mineral Resource estimation and classification.
- Mineral Resources are estimated at a zone definition (wireframe) cut-off grade of approximately 1.0% Cu equivalent grade (CuEq).
- The approximately 1.0% CuEq cut-off grade includes all material in the wireframed zones.
- Bulk density is 3.01 t/m3.
- Resources were estimated to a maximum depth of approximately 1,350 m.
- Copper equivalent (CuEq%) is based on Net Smelter Return Factors as determined for the Preliminary Assessment by Scott Wilson RPA dated January 18, 2008.
- Metal Prices used were $1.75/lb copper, $7.00/lb nickel, $10.00/lb Co, $600/oz Au, $1100/oz Pt and $350/oz Pd.
- Copper equivalent (CuEq%) = Cu% + 3.03 x Ni% + 0.63 x Co% + 0.30 x Au g/t + 0.76 x Pt g/t + 0.24 x Pd g/t based on expected metal prices and process recovery and refining charges.
- TPM is Au g/t + Pt g/t + Pd g/t.
- Co, Au, Pt, Pd grades, that are lacking in historic drill holes, have been entered in the resource database based on regression of assay grades from DML drill hole assays.
- There is no information available on silver recoveries for the Nokomis Deposit; these recoveries would be needed to include silver in the CuEq determination.

*Based on resource estimated at 1.0% copper equivalent cut-off The proposed 2010 program will focus on moving the property towards production and will include additional definition and step-out drilling, metallurgical tests, mine planning, pre-feasibility studies and continued environmental baseline studies.
The Resource Estimate contains all of Duluth Metals in-fill and step-out drill holes (155) as well as all (67) of its wedge holes from the 2006-2009 drill programs. Half core samples were prepared at ALS Chemex Ltd. Laboratories in Thunder Bay and then shipped to its analytical facilities in Vancouver. Samples were analyzed for Au, Pt, and Pd using a standard fire assay with an ICP finish and for 27 other elements using a four acid (near total) digestion and a combination of ICPMS and ICPAES. ICP over limits were re-analyzed using sodium peroxide fusion, acid dissolution followed by ICPAES. The remaining half core samples are being stored in Minnesota.
