Argentina Gold Update

ECR MINERALS plc
(“ECR Minerals”, “ECR” or the “Company”)

 

ECR Minerals plc is pleased to provide the following update on exploration within its Sierra de las Minas gold project area in La Rioja Province, Argentina.

  • High grades including 54 g/t gold, 51.4 g/t gold and 51.2 g/t gold returned by surface geochemical sampling at Cuerpo SI and Don Chiche prospects
  • Preparations for geophysical survey at El Abra gold prospect underway with drilling planned to start within the next 60 days

Further to the Company’s announcement of 15 September 2011, ECR has now received assay results for an additional 25 samples taken at two prospects within the Company’s Sierra de las Minas area during August. Best results from the 25 samples are given in the table below.

All samples were prepared for fire assay and ICP elemental analysis by ACME Analytical Laboratories in Mendoza, Argentina. ACME Analytical Laboratories is certified to ISO 9001 and ISO/IEC 17025 standards.

As with previous sampling, anomalous base metal values, including high grade copper, were returned at both the Cuerpo SI and Don Chiche prospects. Further exploration will seek to establish whether these base metal values are of economic significance.

More detailed sampling of the Cuerpo SI and Don Chiche prospects, along with the Maestro Agüero, Mina San Antonio, Casa Viejas and Mina Azul prospects, is planned. The Company will also continue to conduct first pass sampling of historic prospects at Sierra de las Minas in order to expand the identified prospective areas for further exploration and identify new ones.

Preparations for the ground based pole-dipole geophysical survey planned to commence at the El Abra prospect later this month are continuing and discussions with drilling contractors are underway with regard to the drilling programme that is proposed to follow the geophysical survey at El Abra.

ECR holds 100% exploration rights to the Sierra de las Minas project area and 100% exploitation rights to a number of prospects within it, including the El Abra prospect (save for a 2% NSR royalty payable in respect of production from the El Abra and Jazmin prospects). Exploration rights for other prospects may be converted to exploitation rights by application to the government of La Rioja Province.

 

Patrick Harford, Managing Director of ECR Minerals plc, comments:

“These further high grade assays from sampling at Sierras de las Minas have identified another two exciting prospects as high priority for further exploration. They particularly demonstrate the potential of Sierra de las Minas for the generation of highly promising exploration targets. The project area contains a large number of historic prospects still to be visited for first pass evaluation.

Results from the upcoming drilling and geophysical programme at El Abra will allow a more detailed understanding of the local geology and will be used to guide exploration across the Sierra de las Minas project area.

To date our exploration has shown that the project area contains over 2km of gold bearing quartz veins. At surface, these veins exhibit good mining widths and high grade gold values. Whilst it is too early to place resource numbers on any of the prospects, the upcoming drilling programme at El Abra will indicate whether potentially economic mineralisation continues to depth there and positive drilling results will allow us to plan a more detailed drilling programme in order to fully appraise El Abra with a view to estimating a resource.”
