  *Two high grade nickel intersections with significant off hole
    electromagnetic anomalies
  *Down hole Crone electromagnetic surveys indicate strong conductivity off
    hole from Mex-50 and Mex-111
  *New geophysical and drilling results indicate potential for semi-massive
    to massive sulphide mineralization

Duluth Metals Limited ("Duluth Metals") (TSX: DM) (TSX: DM.U) is pleased to
announce that a zone of high grade nickel-copper mineralization has been
intersected on the southern edge of the Maturi Deposit within the Twin Metals
Minnesota ("Twin Metals") Project in northeastern Minnesota.Drilled as part
of the metallurgical program, Hole MEX276-W1 intersected 26.5 feet of 3.93%
nickel, 0.68% copper, 0.44 g/t silver, and 0.44 g/t TPM (TPM =
Platinum+Palladium+Gold). A follow-up hole, MEX-468 , drilled approximately
300 feet to the southwest intersected 15.0 feet of 1.52% nickel, 0.99% copper,
0.50 g/t TPM . Crone down-hole electromagnetic surveying in MEX-468 has
confirmed extensive off-hole conductivity. As the drill holes are within the
margin of an extensive coincidental conductive zone, there is strong potential
for additional higher grade mineralization within this area.

Geophysical Crone down-hole electromagnetic (EM) surveying in drill-holes
MEX-50, MEX-111 and MEX-468 has shown strong conductivity off-hole from MEX-50
and MEX-111 in a zone extending 2500 feet long by 500 to 1000' wide with
better conductivity in the immediate vicinity of MEX-468 as shown in Figure 1.
The new nickel mineralization occurs as massive to semi-massive sulphides, at,
or immediately below the contact between the South Kawishiwi Intrusion and the
Giants Range batholith.On time, step response data from the Crone survey,
indicates a zone of higher conductivity in close proximity to MEX-468, within
the larger conductive zone. Higher conductivity is indicative of greater
concentrations of conductive minerals, such as massive sulfides.

"Within a massive mineralized system like Twin Metals, our geologists have
always believed there is potential for higher grade pods of mineralization,"
stated Christopher Dundas, Chairman and CEO of Duluth Metals Limited."These
new off-hole anomalies suggest that the conductive zone is extensive and
requires additional drilling to test the central portions for massive and
semi-massive sulphides."

"This drilling shows that the geologic potential of the Twin Metals Project
can continue to evolve," commented, Vern Baker, President of Duluth Metals.
"We see the possibility of higher grade massive sulphide zones within the TMM
project area. The opportunity to find and define these zones may add a new
dimension to what is already a world class project."

Other higher grade nickel intersections have been reported on the margins of
the conductive zone in previous holes drilled by Twin Metals. MEX-276
intersected 5 feet of 1.76% nickel, 0.73% copper, 0.31 g/t TPM ; MEX-439M-W1
intersected 5 feet of 1.56% nickel, 0.55% copper, 0.54 g/t TPM ; and
MEX-439M-W3 intersected 5 feet of 1.18% nickel, 0.98% copper, 0.36 g/t TPM .

In addition, historic hole DU-13 , which is located approximately 3000 feet to
the south within a mineralized area previously referred to as the Nickel Ridge
Area, reported 10 feet of 1.57% nickel, 1.03% copper .(See Duluth Metals
press release dated August 18, 2009.)There is no drilling between this hole
and the newly identified mineralization.

The Twin Metals Minnesota Project covers over 32,000 acres of land/mineral
interests and consolidates the largest base and precious metal land position
in Minnesota. This extensive land position provides Twin Metals with the
platform to plan and develop one the world's largest copper-nickel-PGM
deposits within a new emerging mining belt in Minnesota, USA.

For the 2013 Drill Program, half core samples are being prepared at ALS
Minerals laboratories in Thunder Bay and then shipped to its analytical
facilities in Vancouver. Samples are being analyzed for Au, Pt, and Pd using a
30g standard fire assay with an ICP-AES finish and for 33 other elements using
a four acid (near total) digestion and a combination of ICP-MS and ICP-AES.
ICP over-limits for copper and nickel are re-analyzed using dissolution four
acid (near total) digestion followed by ICP-MS. The remaining half core
samples are being stored in Minnesota.
