VANCOUVER, June 20, 2012 /PRNewswire/ – Callinex Mines Inc. (TSX.V – CNX)
(OTCQX – CLLXF) has entered into an agreement to acquire a 100%
interest in a group of claims known collectively as the “Flin Flon
Claims”. The 44 adjacent claims are located in Northern Manitoba’s Flin
Flon Mining district, south of the operating 777 mine, and near the
formerly producing Schist Lake, Westarm, and Centennial mines. The
claims total approximately 3,798 hectares in area, and are considered
to be highly prospective for VMS style mineralization. Because of their
proximity to known world class VMS deposits in Northern Manitoba, the
Company considers them to be high value exploration targets.

The Flin Flon Caims were optioned from the vendor, Peter C. Dunlop (the
“Optionor”), for consideration of $25,000 and 25,000 shares of
Callinex’ common stock, to be issued within 5 business days of the TSX
Venture Exchange’s approval of the agreement (the “Effective Date”).
Should the company elect to continue operating the property after 12
months following the Effective Date, they shall pay a further $30,000
and 30,000 shares of the company’s common stock to the Optionor. Should
the company elect to continue operating the property after 24 months
from the Effective Date, an additional payment of $45,000 and 45,000
shares of the company’s common stock is due to the Optionor. Finally,
should the company elect to maintain its interest in the property after
36 months from the Effective Date, a final payment of $150,000 and
150,000 shares of the company’s common stock is payable to the
Optionor. Should the company elect to discontinue its operation of the
property at any time prior to the option payments being made, full
undivided ownership of the claims will be returned to the Optionee.

Upon the final payment of all three annual installments of cash and
stock, the Company will own a full 100% interest in the Flin Flon
Claims, subject to a 2% NSR payable to the Optionor (the “Royalty”).
The Optionor holds a 100% interest in the Flin flon Claims except that
nine of the claims are currently subject to a 1% net smelter returns
royalty which the Optionor has agreed to repurchase within 24 months of
the Effective Date. The Company retains the right, exercisable at any
time, to purchase 50% of the Royalty (being 1% of Net Smelter Returns)
from the Optionee for a total payment to the Optionor of $1,000,000.
