Duluth Metals Announces Higher Grade Intercepts With New Twin Metals Drilling Results

TORONTO, Ontario, February 10, 2011 - Duluth Metals Limited ("Duluth Metals") (TSX: DM) (TSX:DM.U) today announced assay results for 15 holes drilled by Twin Metals Minnesota LLC (Twin Metals), on the Nokomis joint venture project in Minnesota, U.S.A. Results of the current drill holes which were drilled within and adjacent to the Central and Eastern High Grade Zones (see press release dated December 11, 2009) confirm and extend the high grade mineralization in these areas. The majority of the holes returned copper equivalent (CuEq) values significantly greater than the Indicated Resource global grade of 1.51% CuEq. In addition, 13 of the 15 holes returned assay intervals of greater than 1 gram per tonne Total Precious Metals, compared to the global average of 0.66 g/t for the Nokomis Deposit (as per Scott Wilson RPA NI 43-101 compliant Resource Report dated December 10, 2009).

Highlights include MEX-194 which returned 120 feet of 0.934% copper, 0.222% nickel, 3.2 g/t silver and 1.925 grams per tonne (g/t) Total Precious Metals (TPM = Platinum+Palladium+Gold) (Cu Equivalent* of 2.35%), including a 30 foot section of 1.181% copper, 0.262% nickel, 3.7 g/t silver and 2.439 g/t TPM (Cu Equivalent* of 2.96%), as well as a 30 foot section of 1.160% copper, 0.263% nickel, 4.4 g/t silver and 2.398 g/t TPM (Cu Equivalent* of 2.88%). MEX-182 intersected 145 feet of 0.827% copper, 0.225% nickel, 3.3 g/t silver and 1.319 g/t TPM (Cu Equivalent* of 1.99%) including a 15 foot section of 0.994% copper, 0.271% nickel, 3.3 g/t silver and 1.640 g/t TPM (Cu Equivalent* of 2.45%), as well as a 15 foot section of 1.576 % copper, 0.583% nickel, 9.9 g/t silver and 2.921 g/t TPM (Cu Equivalent* of 4.21%).

Vern Baker, President of Duluth Metals, stated: "Drilling to better delineate the higher-grade portions of the Nokomis deposit has been very encouraging. The results from drilling have increased our confidence in the quality of grade and continuity within this zone. These results will allow Twin Metals to confidently evaluate a mine plan incorporating this area into early production schedules allowing for improved project economics."

A map illustrating the location of the 15 drill holes reported in this press release can be found on the Company website under this press release at www.duluthmetals.com.

A more detailed summary of the assay results for MEX-182, 183, 183-W1, 184, 185, 186, 187, 188, 189, 190, 191, 192, 193, 194 and 195 can be found in the table below. True width is estimated at about 90% of core length.

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.

About Duluth Metals

Duluth Metals is committed to acquiring, exploring and developing copper, nickel and platinum group metal (PGM) deposits. Duluth Metals has a joint venture with Antofagasta plc on the Nokomis Project, located within the rapidly emerging Duluth Complex mining camp in north-eastern Minnesota. The Duluth Complex hosts one of the world's largest undeveloped repositories of copper, nickel and PGMs, including the world's third largest accumulation of nickel sulphides, and one of the world's largest accumulations of polymetallic copper and platinum group metals. Aside from the joint venture, Duluth Metals retains a 100% position on approximately 31,000 acres of mineral interests on exploration properties adjacent to and nearby the Nokomis joint venture.

About Twin Metals Minnesota LLC

Twin Metals Minnesota LLC is a new joint venture company, which is 60% owned by Duluth Metals and 40% by Antofagasta plc.
