Duluth Metals Receives NI 43-101 Report on Copper-Nickel-PGE Nokomis Deposit and Starts Scoping Study

Posted on: Monday, 13 August 2007, 09:16 CDT

TORONTO, Aug. 13 /PRNewswire-FirstCall/ -- Duluth Metals Limited ("Duluth") (TSX: DM) (TSX:DM.U) announces the receipt of the independent NI 43-101 compliant report completed by 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 Roscoe Postle Associates Inc., Toronto Canada, is the Independent Qualified Person who prepared the report which is available on http://www.sedar.com/ or the Company website at http://www.duluthmetals.com/.

"This technical report summarizes the high quality polymetallic character and consistency of the Nokomis Deposit. The deposit is primarily a copper-nickel-PGM play but has other potential credits including gold, silver and cobalt," stated Dr. Henry Sandri, President. "The Nokomis Deposit covers roughly one-third of our land holdings and the company is continuing drilling to confirm additional mineralization on the rest of our properties."

The Technical Report details the initial resource estimate previously announced by the Company on June 26, 2007. The resource estimate is reported as 347 million tonnes (382 million tons) of the higher classification resource category of Indicated Resources grading 0.62% copper, 0.20% nickel, 0.52 grams per tonne of total precious metals (TPM = Platinum+Palladium+Gold), plus an additional 108 million tonnes (119 million tons) of Inferred Resources grading 0.64% copper, 0.18% nickel, 0.70 grams per tonne TPM.

"The size, extent and consistency of the mineralized resources identified to date has prompted the Company to initiate a formal Scoping Study on the Nokomis Deposit. At the same time we are continuing to drill step-out holes to the East and South on the Maturi Extension Properties and to drill selective in-fill locations. The copper and nickel variograms in the report demonstrate the excellent consistency of copper, nickel and platinum group metal grades and geometry in the area explored to date", said Dr. Henry Sandri, "In other words, the Nokomis Deposit consists of big, contiguous and cohesive blocks of copper, nickel and PGM resources."

The Scoping Study is anticipated to be completed early in the fourth quarter of this year. Drilling is currently underway to upgrade the Inferred portion of the resource to Indicated. The mineralization is also open to the east, northeast and south and the current drilling may also add substantially to the resource in these areas. Based on the continued advancement of the project, the Company plans to start a Pre-Feasibility Study during the fourth quarter of 2007.

The resource estimate, principally located in the western portion of the property, is highlighted below and is also reported at higher cut-off grades as follows:

CIM definitions were followed for Mineral Resource estimation and classification. 2. Mineral Resources are estimated at a zone definition (wireframe) cut- off grade of 0.8% Cu equivalent grade (CuEq). 3. Mineral Resources were estimated using average long-term metal US$ prices of $6.00/lb nickel, $2.00/lb copper, $10/lb Co, $950/oz platinum, $350/oz palladium and $600/oz gold. 4. Bulk density is 3.01 t/m(3). 5. Resources were estimated to a maximum depth of approximately 1,350 m. 6. Copper equivalent (CuEq%) = Cu% + 1.94 x Ni% + 1.77 x Co% + 0.15 x Au g/t + 0.48 x Pt g/t + 0.17 x Pd g/t 7. The 0.8% CuEq cut-off grade includes all material in the wireframed zones. 8. TPM is Au g/t + Pt g/t + Pd g/t. 9. Co, Au, Pt, Pd grades, that are lacking in the few historic drill holes used in the estimate, have been entered in the resource database based on regression of assay grades from DML drill hole assays. 10. Resource blocks at cut-off grades up to and including 0.8% Cu form reasonably coherent areas that could be developed for mining.
