Duluth Metals Announces $8 Million Drilling and Work Program for Exploration Properties

TORONTO, May 5, 2011 /PRNewswire/ -- Duluth Metals Limited ("Duluth Metals" and "Company") (TSX: DM) (TSX: DM.U) is pleased to announce an aggressive spring/summer exploration and drilling program on the Company's 100% owned exploration properties. The Duluth Metals' land position in the Duluth Complex provides an exciting opportunity for future growth outside of the joint venture, while the Twin Metals Project is being advanced by Twin Metals Minnesota LLC. The exploration program is fully financed by the Company which had US$38 million in the treasury as of March 28, 2011.

The spring/summer program on the exploration properties includes:

- Follow-up and evaluation of a 7,053 line kilometre airborne VTEM-Magnetic survey over a 649 square kilometre area within the Duluth Complex which identified high priority targets for follow-up

- Evaluation of 2D and 3D models of magnetic susceptibility, gravity anomalies, and conductivity over the region

- Interpretation of the VTEM-Magnetic survey has been completed by Condor Consulting Inc., a world leader in airborne geophysical analysis

- A budgeted US$6 Million (10,000 meter) drilling program, with drilling on the first target area commencing in June

- A regional glacial till geochemistry and mineralogy program to detect and delineate unexposed mineralization

- Additional geological mapping coordinated with geophysics and geochemistry

- Expansion of the exploration team to 12 people in order to conduct a comprehensive summer field program.

Duluth Metals holds 31,000 acres of high value, grassroots exploration interests in the Duluth Complex. These properties were acquired on the basis of Duluth Metals' expertise on the mineral potential of mafic intrusions in general and the Duluth Complex in particular. This expertise led to the discovery of the world-class Nokomis Deposit, which based on the qualified resource(1) contains over 7.75 billion pounds of Indicated copper and 3.82 billion pounds of Inferred copper; 2.43 billion pounds of Indicated nickel and 1.25 billion pounds of Inferred nickel; and, 11.67 million ounces of Indicated precious metals (platinum+palladium+gold) and 6.03 million ounces of Inferred precious metals. The Company's strategy is to explore close to our known deposits and leverage our exploration team's knowledge of the Duluth Complex mineralizing system in new and innovative ways.

The primary focus is exploration for high-value mafic intrusion-hosted copper-nickel-platinum group metals deposits, including magma conduit-hosted nickel-rich massive sulphides, stratiform platinum-palladium reef style mineralization, as well as Nokomis-style copper-nickel-platinum group metals-rich disseminated sulphides. A budget of $8 Million is allotted for the full 2011 exploration program. While drilling will commence on selected state and private lands in early June, the Company still awaits the issuance of several pending Federal Prospecting Permits.

Geo. is the Qualified Person for Duluth and Senior Geologist for Duluth, in accordance with NI 43-101 of the Canadian Securities Administrators, and is responsible for Duluth's technical content of this press release and quality assurance of the exploration data and analytical results.

(1)The current NI 43-101 compliant Resource Estimate dated December 2009 for the Nokomis Deposit consists of 550 million tonnes of Indicated Resources grading 0.639% copper, 0.200% nickel, 0.660 grams per tonne TPM (TPM = Pt + Pd + Au) for a copper equivalent (CuEq) grade of 1.51%, plus an additional 274 million tonnes of Inferred Resources grading 0.632% copper, 0.207% nickel, 0.685 grams per tonne TPM for a CuEq grade of 1.53% (see December 10, 2009, Technical Report On The Mineral Resource Estimate For The Nokomis Deposit On The Nokomis Property, Minnesota, U.S.A. on http://www.sedar.com.)
