31,000 Acres of 100% Owned Exploration Properties in Close Proximity to the Twin Metals Project

TORONTO, May 5, 2011 - 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
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

- 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.

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

(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,
