TORONTO, April 23, 2012 /PRNewswire via COMTEX/ -- Continued positive drill results in between the Maturi and Nokomis Deposits
Results continuing to show higher grade PGM assays in the area of the "donut hole"
Pre-Feasibility study in progress on Twin Metals Project
The initial pre-feasibility NI-43-101 Resource Estimate report on the consolidated resources of the Twin Metals Project is nearing completion by AMEC

Duluth Metals Limited ("Duluth Metals") (CA:DM)(CA:DMU) is pleased to announce continued strong assay results for 15 holes drilled on the Twin Metals Project in northeastern Minnesota. Three holes, MEX-285, 279 and 273 drilled in the area of the "donut hole" (a parcel internal to the Nokomis resource acquired with Franconia acquisition) continue to demonstrate the continuity of higher grade platinum + palladium + gold (TPM) values in this area.
"These positive drill results continue to show the continuity of mineralization throughout the deposit. Holes MEX 285, 279 and 273 show additional higher grade results from the "donut hole" area acquired from Franconia and strongly indicate the potential for a mineable area with distinctly higher precious metal grades," stated Vern Baker, President of Duluth Metals. "The western holes confirm that Nokomis and Maturi are part of the same mineralized zone, and show relatively thick mineralized widths for that area."
Drilling highlights include:
Mex-285 returned 150.0 feet of 0.724% copper, 0.231% nickel, 2.40 g/t silver and 1.103 grams TPM (Cu Equivalent* of 1.87%) including 89.0 feet of 0.936% copper, 0.284% nickel, 3.02 g/t silver and 1.445 grams TPM (Cu Equivalent* of 2.37%).
Mex-279 intersected 145.0 feet of 0.623% copper, 0.173% nickel, 2.30 g/t silver and 1.272 g/t TPM (Cu Equivalent* of 1.63%) including 94.0 feet of 0.762% copper, 0.202% nickel, 2.66 g/t silver and 1.680 grams TPM (Cu Equivalent* of 2.01%).
Mex-273 intersected 68.0 feet of 0.616% copper, 0.194% nickel, 1.59 g/t silver and 1.202 g/t TPM (Cu Equivalent* of 1.68%) including 30.0 feet of 0.983% copper, 0.275% nickel, 2.25 g/t silver and 2.112 grams TPM (Cu Equivalent* of 2.65%).
One hole, Mex-0278M drilled to the east of the donut hole area returned 89.0 feet of 0.751% copper, 0.213% nickel, 2.86 g/t silver and 1.592 g/t TPM (Cu Equivalent* of 1.99%).
Eleven holes completed between the Maturi Deposit and the Nokomis Deposit demonstrate the continuous, relatively thick mineralization located between the two deposits. Drilling highlights include:
Mex-271 returned 160.0 feet of 0.574% copper, 0.232% nickel, 1.87 g/t silver and 0.451 grams TPM (Cu Equivalent* of 1.46%) including a 115.0 foot section of 0.653% copper, 0.262% nickel, 2.04 g/t silver and 0.517 grams TPM (Cu Equivalent* of 1.66%)
Mex-272 returned 232 feet of 0.625% copper, 0.186% nickel, 1.59 g/t silver and 0.455 grams TPM (Cu Equivalent* of 1.37%) including a 182 foot section of 0.706% copper, 0.206% nickel, 2.00 g/t silver and 0.522 grams TPM (Cu Equivalent* of 1.54%)
Mex-281 returned 153 feet of 0.688% copper, 0.221% nickel, 2.12 g/t silver and 0.725 grams TPM (Cu Equivalent* of 1.64%) including a 139.5 foot section of 0.723% copper, 0.230% nickel, 2.20 g/t silver and 0.773 grams TPM (Cu Equivalent* of 1.72%).

An initial pre-feasibility NI-43-101 compliant Technical Report on the consolidated resources of the Twin Metals Project is nearing completion by AMEC and is anticipated to be finalized in the second quarter of 2012. This report is going through final iterations as minor additions are incorporated into the geologic model. This resource estimate will be used for mine planning purposes in the pre-feasibility study. This initial resource update will be followed up by a final pre-feasibility resource estimate which will incorporate data from recent and current targeted drill programs.
In reference to our last press release dated March 21, 2012 "Duluth Metals Announces Twin Metals Frame-of-Reference for Bechtel Led Pre-Feasibility Study", Duluth Metals would like to correct and clarify the role of Bechtel in the Pre-Feasibility Study. Bechtel Mining and Metals will be leading and preparing the Pre-Feasibility Study for the Twin Metals Project, but will not prepare the Pre-Feasibility NI-43-101 Technical Report. AMEC E&C Services Inc. will be preparing the NI-43-101 Technical Report for the resource estimate that will be used in the Pre-feasibility Study. The selection of the consultant to prepare the NI-43-101 Technical Report on the Twin Metals Minnesota Pre-Feasibility study will occur in the near future.
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 2011-2012 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-AES or AAS. The remaining half core samples are being stored in Minnesota.
