Duluth Announces Appointments Arising out of Corporate Reorganization

TORONTO, July 28, 2010 - Duluth Metals Limited ("Duluth") (TSX: DM) (TSX:DM.U) today announces the
following appointments arising out of a corporate reorganization resulting
from last week's formation of Twin Metals Minnesota LLC ("Twin Metals"), the
new joint-venture company, of which Duluth is the 60% owner, with Antofagasta
plc ("Antofagasta") owning 40%. As an additional part of the reorganization,
Duluth is retaining in its wholly-owned subsidiary, DMC (USA) LLC,
approximately 31,000 acres of mineral interests on exploration properties
adjacent to and nearby the Twin Metals joint venture holdings.

Effective August 7, 2010, Vern Baker is appointed President of Duluth and
DMC (USA) LLC, and will be the lead representative of Duluth to the joint
venture with Antofagasta. Mr. Baker grew up in Reno, Nevada and has a
Bachelor of Science in Mining Engineering from the University of Nevada. He
later attained a MBA degree from Stanford University. Mr. Baker is a highly
experienced mining executive with a focus on underground operations. Vern has
broad experience in mining having previously been the General Manager of such
significant mining operations as the Goldstrike mine in Nevada (Barrick Gold
Corporation), the Homestake mine in South Dakota (Homestake Gold), the Hemlo
mine in Ontario (a joint-venture operation of Teck and Barrick) and the
Stillwater mine in Montana (Stillwater). Most recently, Mr. Baker has been VP
Operations for FNX Mining in Sudbury.

"The addition of Vern Baker to the Duluth team brings tremendous
operational and project development expertise to Duluth Metals as he clearly
has one of the best underground mining track records in North America,"
stated Christopher Dundas, Chairman of Duluth.

Effective immediately, Christopher Dundas, Chairman of Duluth will also
assume the position of CEO of Duluth. In addition, Duluth Metals announces
the appointment of Christopher Dundas, James J. Jackson, and Thomas Pugsley
as Duluth's three nominees to the Board of Twin Metals.

Dr. Henry (Rick) Sandri will be leaving Duluth to pursue other interests.
"Duluth Metals recognizes and appreciates Rick Sandri's significant
contribution to the development and evolution of the Company," said
Christopher Dundas.
