(THE "COMPANY") (TSXV: RCT; OTCBB: RCTFF AND FRANKFURT: R5I): The Board of Directors is pleased to announce the closing of the acquisition by the Company of the remaining 49% interest in the Mina Real Project previously announced on October 19, 2006 by way of acquisition of all of the issued shares of ALB Holdings Inc. ("ALB"). The sole asset of ALB is the 49% equity interest in Mina Real Mexico SA de CV ("Mina Real Mexico"). The Company has issued 10,500,000 common shares to the shareholders of ALB in connection with the acquisition. These shares are subject to a four-month hold period expiring April 2, 2007. In addition, the Company has completed the non-brokered private placement announced on November 30, 2006 for the revised amount of 700,456 units, at $1.15 per unit, with each unit consisting of one share and a full warrant. Each warrant will be exercisable at $1.40 for a term of two years and will contain a forced conversion provision which comes into effect after June 30, 2007 should the shares trade in excess of $2.30 per share for 45 consecutive trading days. The shares and the warrants are subject to a four-month hold period expiring on April 12, 2007. Three associated institutional investors subscribed to 300,000 Units of the aforenoted private placement which brings their combined holding to 3,196,500 common shares and 1,336,900 warrants which, if exercised, would increase their common share holdings to 16.7% of the outstanding shares of the Company. Upon closing of the acquisition and the private placement, the Company will have 25,522,191 common shares outstanding. Dr. Alfredo Parra, the President of Mina Real Mexico and founder of the Mina Real Project, now owns 13.2% of the outstanding common shares of the Company. Dr. Parra, in addition to being President of Mina Real Mexico and the Company's in-house Qualified Perrson, is a member of the Board of Directors of the Company and a QP Member of the Mining and Metallurgical Society of America with special expertise in Mining. "THE CONSTRUCTION OF OUR 200 TONNES/DAY MILL AND RELATED INFRASTRUCTURE IS NOW NEARING COMPLETION AND I EXPECT TO INITIATE START-UP PROCEDURES WITHIN THE NEXT WEEK TO TEN DAYS. METALLURGICAL TESTS INDICATE THAT ONCE THE MILLING OPERATION REACHES ITS DESIGN EFFICIENCY WE SHOULD ACHIEVE RECOVERY RATES IN THE AREA OF 95% FOR GOLD AND BETWEEN 60 AND 92% FOR SILVER, DEPENDING ON THE LEVEL OF MANGANESE IN THE ORE. ONCE THE BASE MILLING OPERATIONS HAVE BEEN STABILIZED A DESIGN ENHANCEMENT WILL BE COMPLETED THAT SHOULD STABILIZE THE RECOVERY OF SILVER AT THE 90% LEVEL. THE COMPANY'S STRATEGY IS TO UTILIZE THE CASH FLOW FROM MINING AND MILLING OPERATIONS TO DEVELOP A 43-101 COMPLIANT RESOURCE RELATIVE TO THE OVER 6 KILOMETERS OF IDENTIFIED VEIN STRUCTURE ON THE MINA REAL PROPERTIES AND EXPAND MINING AND MILLING OPERATIONS TO THE 300+ TONNES/DAY LEVEL BY MID-2007. CONCURRENTLY, THE COMPANY WILL BE CONCENTRATING ON THE ACQUISITION OF ADVANCED EXPLORATION AND DEVELOPMENT PROPERTIES IN THE REGION EITHER SOURCED 100% BY THE COMPANY'S MANAGEMENT OR ACQUIRED THROUGH JOINT VENTURES WITH JUNIOR EXPLORATION ORIENTED COMPANIES OR MAJORS WHO DON'T HAVE THE LOCAL EXPERTISE OR STRATEGIC DESIRE TO OPERATE SMALLER MINING PROJECTS WITH CAPACITY IN THE RANGE OF 200-500 TONNES/DAY."
