Re: News Releases - Monday, July 21, 2008 Title: Duluth Metals Receives Ni 43-101 Report On Interim Nokomis Deposit Resource Estimate Before Commencement Of Pre-Feasibility Study
TORONTO, Ontario, July 21, 2008 - Duluth Metals Limited ("Duluth") (TSX: DM) (TSX:DM.U) today announces the receipt of the 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 Maturi Extension Properties, Minnesota, USA, prepared for Duluth Metals Limited". Richard E. Routledge, M.Sc., P.Geo. of Scott Wilson RPA, Toronto Canada, is the Independent Qualified Person who prepared the report which is available on www.sedar.com or the Company website at www.duluthmetals.com.
"This update on our Resource prepared by Scott Wilson RPA confirms good continuity, grade and the fact that we are delineating zones of higher grade mineralization", stated Henry J. Sandri, President and CEO. "As the Resource is estimated on approximately 50% of our Maturi Extension Properties, we look forward to expanding the Nokomis Deposit and seeking out high grade exploration opportunities."
The Updated Nokomis Resource Estimate defines 449 million tonnes Indicated Resources grading 0.624% copper, 0.199% nickel, 0.600 grams per tonne TPM (copper equivalent grade of 1.46%), plus an additional 284 million tonnes of Inferred Resources grading 0.627% copper, 0.194% nickel, 0.718 grams per tonne TPM (copper equivalent grade of 1.50%). (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 January 22, 2008, NI 43-101 Scoping Study produced by Scott Wilson RPA.)

- 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 Economic 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.
