Constantine Closes Private Placement Financing

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 05/28/12 -- Constantine Metal Resources Ltd. (TSX VENTURE: CEM) ("Constantine" or the "Company") is pleased to announce that it has closed the previously announced private placement agreement with Teck Resources Limited ("Teck") that includes certain rights regarding several of Constantine's Ontario gold properties. Teck invested $525,000 in Constantine at a premium to market through the purchase of 4,200,000 units priced at $0.125. Each unit consists of one common share in Constantine and one-half non-transferable common share purchase warrant. Each warrant is exercisable to acquire one common share at an exercise price of $0.16 for a period of 24 months from the closing date of the private placement. Proceeds of the financing will be used to fund exploration on the Company's Ontario gold properties, including reimbursement for recent airborne geophysical survey work, and general working capital.

All of the above securities are subject to a four-month plus one-day hold period expiring September 26, 2012 in accordance with applicable securities laws and stock exchange rules.

Concurrent with the private placement, Constantine has granted Teck an exclusive right to elect to option the Phoenix and Golden Mile properties, and a right of first offer/first refusal on certain claims in the Munro-Croesus Project area, referred to as the Munro Selection properties. Material terms of the option to joint venture and preferential rights agreements are detailed in a news release dated May 9, 2012. The Munro Selection properties exclude two shaft area claims at the historic high-grade Croesus mine and a contiguous block of eight claims located immediately adjacent and along strike to the west of the 2.1 million ounce Fenn-Gib deposit. None of the above described property rights apply to these ten claims, which remain 100% controlled by Constantine.
