Duluth Metals Announces Aggressive 2011 Program for Twin Metals Project After Acquisition of Franconia

Acquisition of Franconia has significantly expanded the scope and scale of the joint venture development

TORONTO, April 28, 2011 - Duluth Metals Limited ("Duluth Metals") (TSX: DM) (TSX: DM.U) is pleased
to announce a corporate update on the Twin Metals Project. Financing
requirements for the Twin Metals Project are fully covered for the next three
years by Antofagasta plc which is providing US$130 million in funding for the
joint venture operating company, Twin Metals Minnesota LLC ("Twin Metals")
which is 60% owned by Duluth Metals and 40% by Antofagasta plc.

Twin Metals Project

The Twin Metals Project is the new name for the expanded project which
includes the Nokomis Deposit and additional resources on newly acquired
adjacent properties. Three significant NI43-101 compliant resources have been
added to the project with the acquisition of Franconia Minerals Corporation
("Franconia"). These resources include the Maturi Deposit, the Birch Lake
Deposit, and the Spruce Road deposit. Franconia held an undivided 70%
interest in these properties and has exercised its option to increase its
interest to 82% by agreeing to fund all of the carried interest of its joint
venture partner through to commercial production. The Twin Metals Project
encompasses all these resources and the fully contiguous land package that
contains all four resources. The Twin Metals Project is currently in an
extensive review of various scaling and development alternatives for the
expanded project. For the next several years, Twin Metals will be focused on
advancing the Project, as it moves through pre-feasibility towards completion
of a bankable feasibility and a Draft Environmental Impact Statement. Twin
Metals has a dedicated budget of US$130 Million to finance development
activities over a 36 month period.

Current work on the Twin Metals Project includes:

- Drilling with 5 rigs to better understand deposit, including continuity
between Maturi and Nokomis deposits;

- A sixth rig is drilling large diameter core to add to the metallurgical
bulk sample;

- Geological review of old and new core data to provide a fully updated
resource estimate for the full property;

- Additional metallurgical tests conducted on progressively larger
samples;

- Assessment of a range of various scales of operations and a variety of
production alternatives;

- Environmental base line studies to provide inputs for the Environmental
Review Process;

- Construction completion this summer of a new project office for Twin
Metals in Ely, to accommodate the rapidly expanding project program.

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.
