TORONTO, Nov. 10, 2011 /CNW/ - Duluth Metals Limited ("Duluth Metals") (Toronto:DM.TO) (Toronto:DM-U.TO) is pleased to announce assay results for another 16 holes drilled on the Twin Metals Project in northeastern Minnesota. The drill results confirm the continuity of the Nokomis Resource with the Maturi Resource and highlight two higher grade holes in the vicinity of the Eastern Higher Grade Zone:

  • Mex-247 returned 120.0 feet of 0.921% copper, 0.260% nickel, 3.1 g/t silver and 1.335 grams TPM (Cu Equivalent* of 2.22%), including a 15.0 foot section of 1.360% copper, 0.426% nickel, 4.7 g/t silver and 2.101 grams TPM (Cu Equivalent* of 3.45%), and including a 40.0 foot section of 1.160% copper, 0.319% nickel, 3.9 g/t silver and 1.714 grams TPM (Cu Equivalent* of 2.79%).
  • Mex-255 returned 120.0 feet of 0.938% copper, 0.254% nickel, 4.0 g/t silver and 0.950 grams TPM (Cu Equivalent* of 2.08%) including a 50.0 foot section of 1.157% copper, 0.349% nickel, 3.9 g/t silver and 1.255 grams TPM (Cu Equivalent* of 2.72%), including a 20.0 foot section of 1.086% copper, 0.261% nickel, 3.9 g/t silver and 1.119 grams TPM (Cu Equivalent* of 2.31%).

Thirteen drill holes completed in the vicinity of the Nokomis Resource western boundary demonstrate the continuity of the mineralization towards the west. Drilling highlights include:

  • Mex-252 returned 157.0 feet of 0.721% copper, 0.219% nickel, 2.4 g/t silver and 0.544 grams TPM (Cu Equivalent* of 1.60%) including a 35.0 foot section of 0.977% copper, 0.268% nickel, 3.2 g/t silver and 0.731grams TPM (Cu Equivalent* of 2.07%).
  • Mex-258 returned 209.0 feet of 0.741% copper, 0.230% nickel, 2.9 g/t silver and 0.533 grams TPM (Cu Equivalent* of 1.65%) including a 109.0 foot section of 0.866% copper, 0.265% nickel, 3.3 g/t silver and 0.639grams TPM (Cu Equivalent* of 1.92%).

*Note - Copper Equivalent is based on US metal prices of: Copper - $1.75/lb, Nickel - $7.00/lb, Cobalt - $10.00/lb, Gold - $600/oz, Platinum - $1,100/oz, Palladium - $350/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.

Currently a pre-feasibility study is underway on the Twin Metals Project with Bechtel as the lead consultant to analyze and prepare a mine plan and project description for eventual environmental review, permitting, and operations. As the Twin Metals Project has expanded considerably with the acquisition of additional compliant resources, AMEC E&C Services Inc. has been contracted to complete a new NI 43-101 resource estimate for Nokomis, Birch and Maturi and a technical report for Spruce Road, incorporating the four compliant resources under the Twin Metals Project.

"The consistency and scale of the Twin Metals project continues to be sustained by all the drilling.", stated Vern Baker, President of Duluth Metals. "The ongoing drill program, which has six drills turning, is crucial for the Pre-Feasibility study. This drilling will be instrumental in allowing a large portion of the resource to be defined as 'Indicated'. Resources from the 'Indicated' category are critical to building a NI43-101 compliant Pre-Feasibility report."

A map illustrating the location of the 16 drill holes reported in this press release can be found on the Company website under this press release at www.duluthmetals.com. The map shows the designated NI 43-101 resource outlines for the Nokomis, Maturi and Spruce Road Deposits.

The Twin Metals Project 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 copper- nickel-PGM deposits within a new emerging mining belt in Minnesota, USA.

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.
