THEMAC Resources Group Limited Announces a 56% Increase in Recently Updated Measured & Indicated Resource Estimate

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 31, 2012) - THEMAC Resources Group Ltd. (TSX VENTURE:MAC) ("THEMAC" or the "Company") today announced the completion of an updated National Instrument 43-101 (NI 43-101) resource estimate of its 100% owned Copper Flat project located in Sierra County, New Mexico, prepared by M3 Engineering & Technology Corporation (M3) and Independent Mining Company (IMC), both located in Tucson, Arizona.

The recently completed resource estimate reflects the results of a previously announced drilling completed in 2010 and 2011; the re-assay of 2,969 historical pulps to obtain gold and silver values and continued geotechnical and engineering design studies.


  • The total Measured and Indicated Resource increased by 56% to 1,005,891,000 pounds of contained copper from the previously reported 645,000,000 pounds of contained copper.
  • The total Resource (indicated and inferred) of 153,000 Ktons, of which 107,000 was indicated, that was reported in the 2010 Preliminary Economic Analysis (PEA) has been increased to 202,303 Ktons of which 194,097 Ktons is now measured and indicated resources.
  • Only 8,206 Ktons remain classified as Inferred Resources.
  • The re-analysis of 2,969 pulps of historical drill samples has permitted IMC to factor both gold and silver values into approximately half of the current resource model. As a result, additional re-assaying of historical pulps is planned with the intent to increase contained gold and silver.

The resource estimate summarized in the table below was prepared under the supervision of John M. Marek, P.Eng., President of Independent Mining Consultants of Tucson, Arizona who is an Independent Qualified Person as defined under NI 43-101, and reviewed by Raymond Irwin, P.Geo., a Qualified Person for the Company. The subject resource classifications were assigned in conformance with NI 43-101 and its standards and guidelines.

"I am extremely pleased with the progress that is being made on the evaluation of the Copper Flat deposit and the results of the recently completed resource update. The continuing enhancement of the resource from the recent drilling is extremely positive for the economic viability of the copper flat project; and, the recent recovery in the commodity prices may also be expected to add substantially to the value of the resource," said Andre J. Douchane, CEO. "Having a copper resource that now contains a billion pounds puts the Copper Flat Project in a much different league than when it only had 645 million pounds of copper scheduled to be processed. Equally as exciting, we've added 430,000 ounces of gold and 9 million ounces of silver to the resource."


  • The mineral resource is based on the application of the floating cone algorithm to the block model to establish the component of the deposit that has "reasonable prospects of economic extraction." The mineral resources are therefore contained within a computer-generated open pit geometry.
  • Slightly different metal prices were used in the November 2011 resource estimate as compared to the June 30, 2010 study, comprising part of the PEA undertaken by SRK Consulting Inc.
  • The cutoff grade reflects the estimated cost to process the ore plus site general and administrative expenses which total $7.25/ton.
  • Ktons is equivalent to 1,000 short tons, and a short ton is equivalent to 2,000 lbs.
  • Copper and molybdenum grades are dry weight.
  • Gold and silver values are reported in Troy ounce/short ton.
  • Gold and silver values were not available at the time of this study in the outer edges of the deposit so the inferred grades for gold and silver are respectively shown as zero or near zero.

"Along with moving forward with engineering, definitive metallurgical test work and final mill design, we are also finalizing a spring drill program to bring the comparatively higher grade core that was described in earlier work up to NI 43-101 standards," said Ray Irwin, VP Exploration. "As the orebody is still open, the spring drilling program is viewed with optimistic anticipation."

Location and Project History

The Copper Flat project hosts a Laramide porphyry copper-molybdenum deposit containing recoverable gold and silver credits located in the Las Animas Mining District of Sierra County, NM, approximately 150 miles (242 km) south of Albuquerque, NM and 20 miles (32 km) southwest of Truth or Consequences, NM.

The Copper Flat project consists of 26 wholly owned patented mining claims, 184 unpatented mining claims and 29 placer mining claims totaling 4,241.2 acres or 1,717 ha.

This advanced stage exploration/development project operated for a short period of time in 1982 (March-June 1982) by Quintana Minerals Corporation before operations were curtailed due to falling copper prices. During this brief period of production, the Copper Flat mine produced 1.48 Mst of ore yielding 7.4 Mlbs. of copper, 2,301 ounces of gold and 55,966 ounces of silver.
