31,000 acres of 100% owned exploration properties in close proximity to
the Twin Metals Project


7,053 line kilometre airborne VTEM-Magnetic survey completed and
definition of high priority targets for follow-up


Expanding team from 4 to 12 for a summer geochemistry and mapping
program


Initiating drilling in June, and planning additional drilling as year
progresses



TORONTO, May 5 /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 $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 $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.




Phillip Larson, P. 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
