Duluth Metals Announces High Grade Nickel Intercepts Indicative of New Contact Zones in the Maturi Deposit

September 4, 2013
        --  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

TORONTO, Sept. 4, 2013 /PRNewswire/ – 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 = 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

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.

Figure 1 shows the two reported holes, historic drill holes and the
conductive zones.

nickel-rich footwall mineralization including MEX-276-W1 results can be
found in the table below. True width is estimated at about 80-90% of
core length.

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
