Duluth Metals Files New Ni 43-101 Preliminary Assessment Report Confirming Positive Economics For Expanded Nokomis Project

TORONTO, Ontario, January 12, 2009 - Duluth Metals Limited ("Duluth Metals") (TSX: DM) (TSX:DM.U) today announced the receipt of a new independent NI 43-101 Preliminary Assessment ("PA" or Scoping Study) on its Nokomis Project, a large copper-nickel-PGM deposit in Minnesota, from Scott Wilson Roscoe Postle Associates ("Scott Wilson RPA"). Highlights of the study were press released on November 25, 2008 and the full report has now been filed on SEDAR. This report provides an updated Preliminary Assessment of the Nokomis Project, based on the June 2008 Mineral Resource Estimate, and is based on an expanded 40,000 tonne per day ("tpd") production rate scenario, doubling the January 2008 PA production rate case. The report confirms positive economics for the Nokomis Deposit even at today's lower metal prices with the potential to be one of the world's low cost copper-nickel producers.

The new Scoping Study used three metal price scenarios (all monetary units are in $US) to examine the economics of developing and mining the Nokomis Deposit:

• Low-Price Case - reflecting recent low metal prices of 1.55/lb Cu; $4.90/lb Ni; $10.00/lb Co; $795/oz Pt; $295/oz Pd; $600/oz Au.
• Base Case - same base case prices used in the previous Technical Report (January 2008 PA), based on long-term average price forecasts of the past several years. ($1.75/lb Cu; $7.00/lb Ni; $10.00/lb Co; $1,100/oz Pt; $350/oz Pd; $600/oz Au)
• Market-Price Case - prices as of January 13, 2008, for direct comparison to the previously reported 20,000 tpd scenario contained in the January 2008 PA.

Potential annual metal production under the 40,000 tpd expanded production scenario for all three price cases is as follows:

• 181.7 million pounds of copper per annum;
• 42.3 million pounds of nickel per annum; and
• 251,000 ounces of platinum-palladium-gold per annum.

The new independent NI 43-101 Scoping Study was completed by Scott Wilson Roscoe Postle Associates ("Scott Wilson RPA"). Holger Krutzelmann, P.Eng., Jason Cox, P.Eng., and Richard Routledge, M.Sc., P.Geo., of Scott Wilson RPA are the Independent Qualified Persons who are responsible for the report.

This new PA for the Nokomis Project encompasses the following general process flow: Ore production rate of 40,000 tonnes per day, or 14 million tonnes per year; Underground mining by blasthole open stoping with partially recoverable pillars; Underground access by shaft and ramp; Underground ore handling by conveyor systems; Underground primary crushing, further crushing and grinding on surface; Transfer from mine to concentrator via 10 km slurry line; Agitated holding tanks at mill with a minimum capacity of 11,000 m3; Flotation concentration, producing a bulk copper-nickel-cobalt-PGM-gold concentrate; Hydrometallurgical processing using PLATSOL(tm) process; Production of saleable copper and nickel metal via standard electrowinning, and production of cobalt and PGM-gold products to be shipped to refineries for final processing to metal; and a brownfields tailings disposal facility within three kilometers of the processing site.

The following table shows unit cash costs (operating and capital), calculated for either nickel or copper. This measure provides a means to compare costs in dollars per pound of metal to individual metal prices (also in dollars per pound of metal). Scott Wilson RPA notes that the calculation is net of byproduct credits, which in this case amount to approximately 60% of revenue. Since no single metal is a dominant contributor, unit cash costs calculated in this manner appear very low, or negative in most cases.

"We are pleased that the new Preliminary Assessment report indicates that the expanded Nokomis Project is robust at the selected scenarios of long-term metal prices" said Dr. Henry Sandri, President & CEO of Duluth Metals Limited. "Both the new expanded case at 40,000 tonnes per day of production and the earlier 20,000 tonne per day case demonstrate positive economics at various price cases. This demonstrates that the Nokomis Project has significant flexibility in optimizing the production throughput, relative to the overall size of our published resource to date. We are currently in the pre-feasibility data collection and assessment stage of the project and anticipate enhancing the economics by delineating higher grade feed that can be mined and processed at an early stage of the project, studying the impact and staging of various scales of operation, as this 40,000 tpd case is doing, confirming much larger Indicated and Inferred Resources, and converting a significant portion of those resources to Measured Reserves."

Scott Wilson RPA reports their model is sensitive to higher grade and world metal prices. The economic analysis contained in this press release is based, in part, on Inferred Resources, and is preliminary in nature. Inferred Resources are considered too geologically speculative to have mining and economic considerations applied to them and to be categorized as Mineral Reserves. There is no certainty that the reserves development, production and economic forecasts on which this Preliminary Assessment is based will be realized.

The database for the Resource used in the PA was based on 106 drill holes drilled by DML. In completing the 2008 drill program, DML has now drilled 154 holes, of which 48 holes are not included in the current Indicated and Inferred Resources. The new PA has scoped a conceptual mine plan based on a 40,000 tpd operation over a 22 year mine life with average grades of Cu 0.68%, Ni 0.21%, Pd 0.47g/t, Pt 0.21 g/t, Au 0.10 g/t, Co 0.01%. This proposed operation mines 282 million tonnes, which is less than half the resource estimate published by Scott Wilson RPA on July 18, 2008. The current Nokomis Resource Estimate as per the Scott Wilson NI 43-101 Technical Report on the Resource Estimate, dated July 18, 2008, is as follows:

(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, and Palladium - $350/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 January 22, 2008, NI 43-101 Scoping Study produced by Scott Wilson RPA.)
