Duluth Metals Announces 34.5 feet at 2.82% CuEq from Twin Metals New Drilling Results

TORONTO, June 9, 2011 /CNW/ - Duluth Metals Limited ("Duluth Metals") (TSX: DM) (TSX: DM.U) is pleased to announce assay results for 15 holes drilled on the Nokomis Deposit, one of four qualified resources on the Twin Metals Project in northeastern Minnesota. Drilling results continue as expected, with highlights showing higher grade assays from the Eastern, Central and Western Area higher grade zones, as well as two above average holes (Mex-208, 209) approximately 300 metres north-west of the Eastern Area. Four holes (Mex-197, 199, 201, 203) drilled outside of the Central Area, together with Mex-208 and 209 drilled outside the Eastern Area, confirm expansion to the previously released higher grade areas.

In and outside the Eastern Higher Grade area, drilling highlights include:

*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.

"The drilling program of our joint venture company, Twin Metals Minnesota LLC (Twin Metals), continues to confirm the continuity, scale, and grades expected in this deposit. Within the larger in-fill drilling program, the expansion and verification of areas identified as higher grade will allow the Twin Metals team to evaluate economic optimization through mine sequencing", stated Vern Baker, President of Duluth Metals. "The early utilization of higher grade ore will be a major consideration for planning. The drilling and the potential economic benefits of early sequencing of 'high grade zones' make an outstanding project look stronger with every hole."

The Twin Metals Project now 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 nickel-copper-PGM deposits within a new emerging mining belt in Minnesota, USA.

The Twin Metals Project is currently in the pre-feasibility phase. Separate consulting engineering firms are being engaged for both the overall pre-feasibility study and an updated resource report. AMEC E&C Services Inc. from Reno, Nevada has been engaged to review and prepare a comprehensive updated NI 43-101 Resource Report on the expanded Twin Metals Project which now includes the Twin Metals and Franconia properties.

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.

David Oliver, P. Geo. and Twin Metals Site Manager is the Qualified Person for this press release, in accordance with NI 43-101 of the Canadian Securities Administrators, and is responsible for the technical content and quality assurance of the exploration data and analytical results.
