*Note - Copper Equivalent is based on US metal prices of: Copper - $1.75/lb, Nickel - $7.00/lb, Cobalt - $10.00/lb, Gold - $600/oz, Platinum - $1,100/oz, Palladium - $350/oz and Silver - $8.50/oz, and the methodology with metallurgical recoveries, refining costs and other charges being considered for all metals in accordance with the Net Smelter Return Factors contained in the December 10, 2009 Technical Report On The Mineral Resource Estimate For The Nokomis Deposit On The Nokomis Property, Minnesota, U.S.A. by Scott Wilson RPA.

A map illustrating the location of the 8 drill holes reported in this press release can be found on the Company website under this press release at www.duluthmetals.com.  The map shows the designated NI 43-101 resource outlines for the Nokomis, Maturi and Spruce Road Deposits.  (see Franconia's company profile on Sedar at www.SEDAR.com for the October 20, 2006 Technical Report on the Preliminary Assessment of the Birch Lake and Maturi Deposits, Minnesota, U.S.A by Scott Wilson Roscoe Postle Associates; and the November 15, 2007 Technical Report on the Resource Estimate for the Spruce Road Deposit, Minnesota, U.S.A by Scott Wilson Roscoe Postle Associates; Cut-off grade 0.5% Cu.; see Duluth's company profile on Sedar at www.SEDAR.com for the December 10, 2009 Technical Report On The Mineral Resource Estimate For The Nokomis Deposit On The Nokomis Property, Minnesota, U.S.A.  Cut-off grade at 1.0% CuEq, **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).

As the Twin Metals Project has expanded considerably with the acquisition of the three Franconia qualified resources, AMEC E&C Services Inc. has been contracted to complete a new NI 43-101 technical report incorporating the four qualified resources within the Twin Metals Project: the Nokomis, Birch, Maturi and Spruce Road Deposits.  The summary results for this report are expected by February, 2012. With today's press release, the results of all drill holes included in the upcoming technical report (up to MEX 269) have been released.

"These positive drill results continue to be extremely encouraging. Holes MEX 262 and MEX 267 are the first reported results from the "donut hole" area acquired from Franconia. They show good grades and strongly indicate the expansion potential of the Central and Eastern High Grade Zones", stated Vern Baker, President of Duluth Metals. "The western holes confirm great continuity between Nokomis and Maturi. Overall the development drilling also shows the strong PGM component of the project."

A more detailed summary of the assay results for MEX-261 to 269 inclusive can be found in the table below. True width is estimated at about 90% of core length.

The Twin Metals Project covers over 25,000 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 2010-2011 Drill Program, half core samples are being prepared at ALS Chemex Ltd. laboratories in Thunder Bay and then shipped to its analytical facilities in Vancouver. Samples are being 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.

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's technical content of this press release and quality assurance of the exploration data and analytical results.
