Nuinsco Extends Diabase Peninsula Uranium Project Agreement

Continued Exceptional Results Warrant Further Exploration

TORONTO, ONTARIO -- (Marketwire) -- 06/12/12 -- Nuinsco Resources Limited ("Nuinsco" or the "Company")(TSX: NWI) (www.nuinsco.ca) today announced an agreement has been reached with Dr. Lloyd Clark to extend the joint venture agreement concerning the Diabase Peninsula Project, located in the Athabasca Basin, northern Saskatchewan.

"The extension is warranted because of the continued excellent results that indicate that the rocks underlying the property have been subjected to a uranium mineralizing event capable of causing the formation of uranium bearing zones," said Paul Jones, President.

Under the terms of the original agreement between Dr. Clark and Trend Mining Company ("Trend") dated September 2, 2004, a cash payment of $935,000 was due to Dr. Clark on September 2, 2012. Nuinsco subsequently assumed responsibility for the original agreement when the Company entered into an option/joint venture agreement with Trend. The agreement with Dr. Clark has been extended for one year in exchange for a payment consisting of cash and common shares of Nuinsco totalling $75,000 and allows for an option to extend the agreement further. In reaching the agreement with Dr. Clark, Nuinsco will be well placed to direct more funds to exploring and advancing this excellent project that has been evaluated as a leader in the race to find the next uranium "Super Deposit" in the Athabasca Basin by the Northern Prospector magazine.

Of particular note with regard to results obtained to date, which indicate high potential for an Athabasca Basin-type deposit, are the following:

1.  42 drill holes have been completed on the project to date; 14 holes have
    returned samples with very substantial uranium content exceeding 50ppm
    and peaking at 707ppm uranium (greater than 10ppm uranium in sandstone
    is evidence of a mineralised system and proximity to concentrations of
    high-grade mineralisation). In total, 28 drill holes have returned
    values greater than 10ppm uranium - serving to further reinforce and
    highlight the outstanding scale of anomalous mineralization at Diabase.

2.  The combination of uranium-arsenic-nickel-cobalt-magnesium oxide, which
    typifies several of the mines in the Athabasca district, is present in
    drill holes and indicates the influence of a mineralizing system in the
    area - pointing to the presence of some form of unconformity
    mineralization nearby.

3.  The widespread presence of significant clay alteration in the sandstone
    which indicates the passage of hydrothermal fluids capable of
    transporting uranium mineralization.

4.  Uranium/lead ratios which provide evidence of local excess uranium in
    the Athabasca Basin sediments and suggest upward leakage of uranium-
    bearing hydrothermal fluids.

5.  The presence, established by more than 100m vertical displacement of the
    unconformity occurring between adjacent drill holes, of reactivated
    faults which provide permeable conduits that trap and concentrate
    uranium-bearing mineralizing fluids to create the small footprint but
    high-grade deposits found in the Athabasca Basin.

The Diabase Peninsula Project is located in the south-central part of Saskatchewan's Athabasca Basin, home to the highest grade uranium deposits in the world. A combination of uranium-arsenic-nickel-cobalt-magnesium oxide is typical of the mines in the Athabasca Basin. The widespread presence of this combination of elements in the holes drilled by Nuinsco indicates the influence of a mineralizing fluid, capable of forming deposits of uranium, on the Diabase Peninsula property.

The 21,959 hectare Diabase Peninsula Project is located approximately five kilometres north of the southern boundary of the Athabasca Basin. It encompasses a 35 km strike length above the regional-scale Cable Bay Shear Zone deformation zone in the basement rock units below the basin sandstone.
