THEMAC RESOURCES UPDATE

London: 19 December 2012 - ECR Minerals plc is pleased to draw attention to the news release made today by THEMAC Resources Group Ltd (“THEMAC”). The full text of the release is provided below.

ECR owns approximately 19% of THEMAC’s issued share capital and has a fully diluted interest in THEMAC of approximately 21%. THEMAC is listed on the TSX Venture Exchange with the code MAC.

The Company also provides the following update with regard to its holding in THEMAC and its former holding in West Wits Mining Ltd.

THEMAC

ECR is aware of its shareholders’ enthusiasm for THEMAC and the Copper Flat project and in view of this the Company’s directors (the “Directors”) are considering the possibility of a distribution to ECR shareholders of part of the Company’s holding of THEMAC shares and warrants.

Presently the book value of ECR’s investment in THEMAC is substantially in excess of the Company’s market capitalisation. By distributing some of the securities comprising the investment, it could be expected that substantively more of this value would become tangible to ECR shareholders, who would become holders of THEMAC shares and/or warrants directly.

Any such distribution would require court approval, as well as the approval of ECR shareholders and convertible loan note holders. There is no certainty that any of these approvals could be obtained, and the process of seeking the approvals and, if permitted, making the distribution would take a number of months.

Before seeking court approval, it would likely be necessary for ECR to secure an increased level of working capital in order for the Directors to be in a position to make representations to the court with regard to safeguarding the position of the Company’s creditors, which would be customary in the court process.

In parallel, ECR remains open to opportunities to dispose of some or all of its interest in THEMAC for an acceptable cash value.

West Wits Mining

ECR has now disposed of its entire shareholding in West Wits Mining (ASX: WWI). The proceeds of the disposal, totalling approximately AUD 170,000, will be used to fund the ongoing activities of the Company.

THEMAC Copper Flat Update: Planned Geotechnical Drilling Intersects and Confirms Copper-Molybdenum Grades; Drill Hole Assays 0.66% Cu and 0.084 oz Ag per Ton Over 80 Feet

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 19, 2012) - THEMAC Resources Group Limited (TSX VENTURE:MAC) ("THEMAC" or "the Company") today provided an update on its 2012 core drilling program at the Company's Copper Flat project in New Mexico.

2012 GEOTECHNICAL CORE DRILLING PROGRAM-Results for Holes CNI 12-01 through CNI 12-06

During the period August 12 to September 12, 2012, the Company completed, as part of the 2012 Drilling Program, five angled geotechnical core holes totaling 3,609 feet. These holes were designed to provide geotechnical information (rock strength data), and should confirm that the average pit walls can be steepened, which has the possibility to reduce future waste removal. Once the final geotechnical report is received, the design of an optimized pit and associated final reserve and resource model can be completed for inclusion in the Feasibility Study.

"The Geotechnical Report is scheduled to be delivered during December 2012 and once we have the report we will immediately begin to optimize the pit," said Andre Douchane, CEO. "Depending on the workload of our contractor, we anticipate having completed the final pit design early in 1st quarter 2013 for inclusion in the Feasibility Study, which is on schedule for completion around the end of 1st quarter 2013."

In addition to providing the geotechnical information needed for the design of the optimized pit and the revised reserve and resource estimate, four of the five holes (CNI 12-01, CNI 12-03, CNI 12-04 and CNI 12-05) intersected and confirmed the presence of significant copper-molybdenum mineralization along or near the outer margins of the Copper Flat deposit. It should be noted that planned drill site CNI 12-02 was not drilled, while geotechnical hole CNI 12-06 contained no significant mineralization.

"We were excited to see the long continuity of reserve grade present in all four holes," said Ray Irwin, Vice President Exploration. "When combining the results from these four holes with our earlier drilling, we can clearly see that the mineralization is extending to the northeast and remains open to some degree along the deposit's major northeast trending structure."

The assay results presented below are based on a 0.20% Cu only cutoff unless there is a less than 0.20% Cu sample within a broader zone of Cu values that equal or exceed 0.20% Cu. The intervals and thicknesses reported are along the core axis.

Assay Methods

Assaying for the 2012 drilling program is being undertaken at the Skyline Laboratory in Tucson, AZ. Copper and molybdenum values are being determined by ICP/MS, gold by fire assay with AA finish, and silver by AA. Reference standards and blanks were inserted in the sample streams, and every tenth sample was objectively validated by ALS Minerals, Reno, Nevada using similar methodologies.

Standard procedures for core handling were in place during the entire drilling program, and a geologist was on site for all sample preparation and shipping.

About the Copper Flat Project

Copper Flat is a former producing mine located in Sierra County, State of New Mexico approximately 150 miles south of Albuquerque and 20 miles southwest of the town of Truth or Consequences.

Copper Flat is a porphyry copper-molybdenum deposit containing economically recoverable gold and silver mineralization hosted by a quartz monzonite stock which intrudes an andesitic volcanic complex. The Cretaceous (75 million years ago [Ma]) Copper Flat quartz monzonite hosts mineralization dominated by pyrite and chalcopyrite with subsidiary molybdenite. The mineralization is focused along intersecting northeast and northwest-trending faults, the intersection of which is associated with the host intrusive.

The project has an estimated $54 million benefit and financial savings from the civil infrastructure that is currently in place at Copper Flat including a tailings dam, largely pre-stripped open pit, power lines, water well field and pipeline, access roads, diversion channels and usable process building foundations. The Copper Flat land package comprises in excess of 1,200 hectares, and the deposit is located entirely on patented mining claims wholly-owned by THEMAC Resources Group.

Permitting for the return of the project to production is at an advanced stage, and a feasibility study is targeted for completion in March of 2013.
