Duluth Metals Announces 120 Feet of 2.19g/t Total Precious Metals 350 Metres East of the Current Twin Metals Nokomis Resource
TORONTO, July 7, 2011 /PRNewswire/ --
Duluth Metals Limited ("Duluth Metals") (TSX: DM) (TSX: DM.U) is pleased to announce assay results for 15 holes drilled on the Twin Metals Nokomis Deposit in northeastern Minnesota, including 9 holes containing intersections with Total Precious Metals (TPM (equal sign) Platinum+Palladium+Gold) grades greater than 1g/t and 11 holes having intersections greater than 1.7% Copper Equivalent(x). Three holes, Mex-211, 217 and 225, intersected significant mineralization up to 350 metres due east of the current Nokomis resource, thereby expanding the current mineralized area southwards. This includes a 25 foot intersection in Mex-225, containing 3.385 g/t TPM within a 120 foot section of 2.19g/t TPM. Four holes, Mex-218, 220, 223 and 224 continue to confirm higher grade assays in the Eastern Higher Grade Zone, and two holes, Mex-212 and 219 continue to confirm higher grade assays in the B Higher Grade Zone. The Nokomis Deposit is one of four qualified resources within the Twin Metals Project being advanced by the joint venture company Twin Metals Minnesota LLC.
Highlights from expansion drilling south of the current Nokomis Deposit include:
- Mex-225 returned 185.0 feet of 0.710% copper, 0.184% nickel, 3.1 g/t
silver and 1.642 grams per tonne (g/t) Total Precious Metals (TPM
(equal sign) Platinum+Palladium+Gold) (Cu Equivalent(x) of 1.92%),
including a 120.0 foot section of 0.835% copper, 0.230% nickel, 3.6
g/t silver and 2.190 g/t TPM (Cu Equivalent(x) of 2.40%), as well as a
25.0 foot section of 1.100% copper, 0.325% nickel, 5.9 g/t silver and
3.385 g/t TPM (Cu Equivalent(x) of 3.39%). - MEX-217 intersected 267.5 feet of 0.698% copper, 0.184% nickel, 2.3
g/t silver and 1.139 g/t TPM (Cu Equivalent(x) of 1.72%) including a
20 foot section of 0.986% copper, 0.251% nickel, 3.4 g/t silver and
1.887 g/t TPM (Cu Equivalent(x) of 2.49).
Within the Eastern Higher Grade area, drilling highlights include:
- Mex-224 returned 170.0 feet of 0.690% copper, 0.180% nickel, 3.0 g/t
silver and 1.616 grams TPM (Cu Equivalent(x) of 1.86%), including a
87.0 foot section of 0.892% copper, 0.243% nickel, 3.5 g/t silver and
2.166 g/t TPM (Cu Equivalent(x) of 2.47%) as well as a 50.0 foot
section of 1.089% copper, 0.302% nickel, 4.2 g/t silver and 2.737 g/t
TPM (Cu Equivalent(x) of 3.06). - MEX-223 intersected 95.0 feet of 0.749% copper, 0.186% nickel, 2.5 g/t
silver and 0.738 g/t TPM (Cu Equivalent(x) of 1.60%) including a 50.0
foot section of 1.000% copper, 0.252% nickel, 3.1 g/t silver and 1.054
g/t TPM (Cu Equivalent(x) of 2.17). - MEX-220 intersected 125.0 feet of 0.786% copper, 0.195% nickel 4.0 g/t
silver and 1.566 g/t TPM (Cu Equivalent(x) of 2.00%) including a 30.0
foot section of 1.140% copper, 0.241% nickel, 7.1 g/t silver and 2.125
g/t TPM (Cu Equivalent(x) of 2.76). - MEX-218 intersected 80.0 feet of 0.695% copper, 0.188% nickel, 2.9 g/t
silver and 0.978 g/t TPM (Cu Equivalent(x) of 1.65%) including a 55.0
foot section of 0.809% copper, 0.208% nickel, 3.3 g/t silver and 1.129
g/t TPM (Cu Equivalent(x) of 1.89).
(x) Note - Copper Equivalent is based on US metal prices of: Copper - US$1.75/lb, Nickel - US$7.00/lb, Cobalt - US$10.00/lb, Gold - US$600/oz, Platinum - US$1,100/oz, Palladium - US$350/oz and Silver - US$8.50/oz, and the methodology with metallurgical recoveries, refining costs and other charges being considered for all metals in accordance with the Net Smelter Return Factors contained in the January 22, 2008, NI 43-101 Scoping Study produced by Scott Wilson RPA.
"The drilling program continues to provide results that increase our confidence in this resource. These results also indicate that areas of significantly higher TPMs can be identified within the resource. Two exciting intersections with very good precious metal results, 50 feet of 2.737g/t TPM in Mex-224 and 25 feet of 3.385 g/t TPM in Mex-225, show the potential within this resource to define areas with higher TPM values", stated Vern Baker, President of Duluth Metals. "Overall, the drilling this year has been quite encouraging. Three of the drill holes included in this release (Mex-211, Mex-217, Mex-225) show the continuity of the resource extending beyond the previous limits."

The Twin Metals Project now covers over 25,000 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 nickel-copper-PGM deposits within a new emerging mining belt in Minnesota, USA.
AMEC E&C Services Inc. from Reno, Nevada has been engaged to review and prepare a comprehensive updated NI 43-101 Resource Report on the expanded Twin Metals Project which now includes the Twin Metals and Franconia properties.
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.
David Oliver, P. Geo. and Twin Metals Site Manager is the Qualified Person for this press release, in accordance with NI 43-101 of the Canadian Securities Administrators, and is responsible for the technical content and quality assurance of the exploration data and analytical results.
