Title: Duluth Metals Expands Higher Grade Area on Nokomis Deposit

TORONTO, Ontario, April 22, 2010 - Duluth Metals Limited ("Duluth Metals") (TSX: DM) (TSX:DM.U) today announced results for six holes drilled in the 2010 Winter Drilling Program on the Nokomis Deposit, Ely Minnesota. Significantly higher grade intersections have been returned for five of the holes, which together with previously reported hole MEX-158, indicates the potential for a larger higher grade area situated in the north central section of the currently defined Nokomis Deposit.

These six drill holes (MEX 157, 158, 159, 160, 161 and 164) are located in proximity to previously announced higher grade zones (see press release dated December 11, 2009) which were highlighted in the most recent NI 43-101 Resource Estimate dated December 2009. A map illustrating the location of these six drill holes in relation to the higher grade areas published in the December 11, 2009 press release can be found on the Company website under this press release at www.duluthmetals.com.

"These 2010 Winter Drill Program results indicate that some of the previously defined, higher grade areas within the Nokomis Deposit are growing in size. Increasing tonnage in our higher grade areas will clearly add to the already positive economics of the Nokomis Project", stated Dr. Henry J. Sandri, President and CEO of Duluth Metals. "The focus of our current 2010 Spring Drill Program is to continue to further evaluate and quantify theses notable higher grade copper, nickel, platinum, palladium, gold and silver zones in portions of the Nokomis Deposit."

For the 2010 Winter 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.
