Constantine Announces Partner-Funded Winter Exploration Program-Golden Mile Property, Ontario

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 17, 2012) - Constantine Metal Resources Ltd. (TSX VENTURE:CEM) ("Constantine" or the "Company") is pleased to announce Teck Resources Limited ("Teck") is planning a winter exploration program on the Company's Golden Mile property in Timmins, Ontario, comprising approximately $600,000 in exploration expenditures The large, 68 square kilometer, Golden Mile Property is located 9 kilometers northeast of Goldcorp's multi-million ounce Hoyle Pond deposit and covers the Pipestone Fault System where it crosses the "Porcupine Giant Mine Corridor" that has produced more than 55 million ounces of gold. The winter program is designed to follow-up on targets generated from Teck-funded exploration and compilation work carried out in August and September, and is planned to include overburden drilling and ground-based geophysical surveys, subject to permit approvals and ongoing stakeholder consultation.

A small overburden drill program conducted in the 1980s identified a strong gold-in-till anomaly at the southern edge of the property, suggesting the potential for a significant gold mineralized bedrock source located up-ice to the north of these drill holes. Defining gold-grain dispersal trains with overburden drilling is a proven technique for tracing glacially transported gold back to its bedrock source. The combination of the historic gold-grain data and interpretations of geological, geochemical and geophysical work completed by Constantine has defined a large prospective area for gold mineralization. This area is the focus of the planned winter program, with the objective of identifying and refining diamond drill targets. Details for the winter work program are being finalized and Constantine is currently targeting start-up in early 2013.
