Duluth Metals Announces Higher Grade Intercepts With New Twin Metals Drilling Results
By Duluth Metals Limited, PRNEWednesday, February 9, 2011
TORONTO, 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 (equal sign) Platinum+Palladium+Gold) (Cu Equivalent(x) 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(x) 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(x) 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(x) 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(x) 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(x) 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

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.

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.

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 (equal sign) 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%.
