Duluth Metals Limited announced assay results for the first 20 holes, MSW-0001 to MSW-0020, in the Maturi West Exploration Target area, including the up dip extension of the Birch Lake deposit, within the Twin Metals Minnesota Project ("TMM") in northeastern Minnesota. Assay results from the relatively shallow drilling highlight thick mineralized intersections which include: MSW-0014 returned a 150 foot intersection of 0.81% copper, 0.27% nickel, 2.7 g/t silver and 1.00 grams TPM (TPM = Platinum+Palladium+Gold) at a 0.3% Cu cut-off including a 110 foot intersection of 0.94% copper, 0.31% nickel, 3.1 g/t silver and 1.17 grams TPM at a 0.5% Cu cut-off; MSW-0017 returned a 210.5 foot intersection of 0.64% copper, 0.24% nickel 2.1 g/t silver and 0.35 grams TPM at a 0.3% Cu cut-off including a 120.5 foot intersection of 0.72% copper, 0.24% nickel, 2.6 g/t silver and 0.44 grams TPM at a 0.5% Cu cut-off; and MSW-0018 returned a 83 foot intersection of 0.60% copper, 0.19% nickel, 2.1 g/t silver and 0.41 grams TPM at a 0.3% Cu cut-off including a 50 foot intersection of 0.90% copper, 0.28% nickel, 3.7 g/t silver and 0.51 grams TPM at a 0.5% Cu cut-off. The Twin Metals Minnesota Project covers over 32,000 acres of land/mineral interests and consolidates the large base and precious metal land position in Minnesota. This extensive land position provides Twin Metals with the platform to plan and develop large copper-nickel-PGM deposits within a new emerging mining belt in Minnesota, USA. For the 2013 Drill Program, half core samples are being prepared at ALS Minerals laboratories in Thunder Bay and then shipped to its analytical facilities in Vancouver. Samples are being analyzed for Au, Pt, and Pd using a 30g standard fire assay with an ICP-AES finish and for 33 other elements using a four acid (near total) digestion and a combination of ICP-MS and ICP-AES. ICP over-limits for copper and nickel are re-analyzed using dissolution four acid (near total) digestion followed by ICP-AES or AAS. The remaining half core samples are being stored in Minnesota.

Duluth Metals Limited filed its Annual on Apr 01, 2013 for the period ending Dec 31, 2012. In this report its auditor, KPMG LLP, gave an unqualified opinion expressing doubt that the company can continue as a going concern.
