MAC Themac Resources Group Ltd

THEMAC Resources Group Limited (TSX VENTURE: MAC) ("THEMAC" or "the Company") is pleased to announce that, on June 29, 2011, the Company selected Tucson-based M3 Engineering and Technology Corporation to complete the pre-feasibility study for its Copper Flat Project. M3 is a full-service design firm specializing in architecture, engineering and construction management, and has 24 years of mining experience.

The pre-feasibility study will be Canadian Securities Administrators (CSA) National Instrument 43-101 (NI 43-101) compliant and is expected to be completed in December 2011.

M3 Engineering will be the primary study provider and report author, with input by Independent Mining Consultants; Golder and Associates; Parametrix; Intera; Shomaker and Associates, and SRK-Reno.

The pre-feasibility study will reflect the additional benefits of inclusion of gold and silver recoveries identified from an on-going pulp re-assay program overseen by SRK-Vancouver.

"We much look forward to refining our cost estimates and providing further evidence of the project's overall economic robustness," said Barrett Sleeman, CEO of THEMAC Resources Group.

About the Copper Flat Project

Copper Flat is a former producing mine located approximately 20 miles southwest of Truth or Consequences in Sierra County, State of New Mexico, USA. Permitting for a return of the project to production is at an advanced stage, and a pre-feasibility study is in progress and targeted for completion during 2011.

The Copper Flat project is a porphyry copper-molybdenum-gold-silver deposit. The deposit has NI 43-101 Indicated Mineral Resources of 107 million short tons grading 0.303% copper and 0.01% molybdenum for 645 million lbs copper and 21.4 million lbs molybdenum, plus Inferred Mineral Resources of 46 million short tons grading 0.24% copper and 0.006% molybdenum for 222 million lbs copper and 5.6 million lbs molybdenum.

The gold and silver content of the deposit is evidenced by historic production and metallurgical test work, and gold and silver are targeted for incorporation into the deposit's NI 43-101 Mineral Resource statement following completion and interpretation of a re-assay program using historic drill pulps.

An NI 43-101 Preliminary Economic Assessment ("PEA") dated June 30, 2010 and updated February 25, 2011 has been completed for Copper Flat and can be viewed on SEDAR.

Civil infrastructure in place at Copper Flat includes a tailings dam, largely pre-stripped open pit, power lines, water well field and pipeline, access roads, diversion channels and building foundations. The project land package comprises in excess of 1,200 hectares. For more information visit www.nmcopper.com.
