THEMAC Resources Group Announces Completion of Positive Prefeasibility Study

IRR of 36.2% Anticipated At Current Copper, Moly, Gold and Silver Prices

VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 19, 2012) - THEMAC Resources Group Limited (TSX VENTURE:MAC) ("THEMAC") today announced positive economics from a prefeasibility of its 100% owned Copper Flat Mine in New Mexico, completed by M3 Engineers of Tucson, Arizona.

Copper Flat is a former producing mine located in Sierra County, State of New Mexico, USA, approximately 150 miles south of Albuquerque and 20 miles southwest of the town of Truth or Consequences. The project land package comprises in excess of 1,200 hectares, and the ore reserves are located entirely on patented mining claims wholly-owned by THEMAC. The Copper Flat project will consist of a conventional drill and blast, truck and shovel operated mine having an overall estimated strip ratio of 0.6 tons of waste to 1 ton of ore. The mill is designed to have a simple SAG ball mill grinding circuit followed by a conventional floatation circuit.

Highlights of the Prefeasibility

  • Pre-tax IRR of 36.2% based on July 10th metal prices yields a US$388.5 million pre-tax NPV at an 8% discount rate or US$5.24 per share based on 74.1 million shares on issue
  • US$0.79 estimated operating cost per pound of copper for the first two years at July 10th prices and after byproduct credits
  • Payable production for the first two years is forecasted to be 130.57 million pounds of copper, 2.63 million pounds of molybdenum, 24,000 ounces of gold and 1.086 million ounces of silver
  • Proven and Probable reserves of 98.118 million tons containing 608.5 million pounds of copper, 18.1 million pounds of molybdenum, 295,000 ounces of gold and 6.48 million ounces of silver
  • Initial capital costs estimated to be US$297.7 million with Mine costs at US$28.3 million, Process at US$250.2 million and Owners Costs of US$ 19.2 million - costs include contingency
  • Value of existing infrastructure estimated at US$54 million

"I am extremely pleased that the prefeasibility study indicates a very viable project at Copper Flat," said André J. Douchane, CEO. "The Study shows a robust pre-tax return on investment of 36.2% at metal prices recorded on Tuesday, July 10, 2012. On that day copper and molybdenum were trading in the range of US$3.40 and US$12.50 per pound respectively, and gold and silver were trading around US$1580.00 and US$27 per ounce respectively."

The prefeasibility study for Copper Flat is based on the following general assumptions:

  • Proven and probable reserves of 98.118 million tons containing per ton 0.31% copper, 0.009% molybdenum, 0.003 oz. gold and 0.070 oz. silver
  • Milling rate of 9.125 million tons per year or nominal 25,000 tons per day
  • Mill recoveries estimated at 91.8% for copper, 60.7% for molybdenum, 70.8% for gold and 90.0% for silver.
  • Open pit pre-stripped from previous operation
  • Utilization of US$54 million in existing infrastructure
  • Average annual payable production of 50.76 million lbs. copper, 1.01million lbs. molybdenum, 12,750 oz. gold and 455,390 oz. silver
  • Base case model utilized prices of US$3.00 copper, US$12.00 molybdenum, US$1350.00 gold and US$25.00 silver, which yields an IRR of 26.7% and a pre-tax NPV of $242.3 million at an 8% discount rate
  • Average copper equivalent grade of based base case prices of 0.44% per ton

The study's base case estimated average operating cost of US$1.11 per pound of copper recovered was calculated assuming molybdenum, gold and silver as byproduct credits against operating costs of US$10.54 per ton processed.

Capital costs are estimated to be US$297.7 million. The mine capital portion of the total is US$28.3 million, the process is US$250.2 million and the owner's costs are US$19.2 million. Life of mine sustaining capital is estimated to be US$26.9 million for the mine and US$39.9 million for the process. A contingency of nearly 15% is included in all capital estimates.

These reserves and resources, which begin at the surface, are currently being updated to include the results of the last four holes drilled during the 2011 program, as well as the results of the first seven holes (CF12-01 through CF12-07) completed during the ongoing 2012 drilling program, which were released on June 27, 2012. During the coming months, as drilling results become available, additional reserve and resource updates are planned.

"This study was done to what I believe are the highest standards in the industry, and a lot of planning and innovation went into this study," said Mr. Douchane. "The ability to incorporate all of the existing foundations, power lines, flood control, water wells, water pipeline and surface roads into the design appears to have saved us an estimated US$54 million in capital costs. We expect the Record of Decision from the BLM and the State Mining Permit to be issued during third quarter 2013 by which time the definitive feasibility and all of the detailed engineering will have been completed. All major and long lead equipment is also planned to be available by the same time. If everything happens as anticipated, construction can start during fourth quarter 2013 and start-up of operations the following year end."

The prefeasibility study was prepared under the supervision of Conrad Huss, P.E. of M3 Engineers of Tucson, Arizona, who is an Independent Qualified Person as defined under Canadian NI43-101. Resources and reserves were calculated by IMC of Tucson, Arizona under the supervision of John Marek, P.E. &President, who is an Independent Qualified Person as defined under Canadian NI43-101.

The final prefeasibility report will be filed on SEDAR within 45 days of the date of this press release.
