Restoration of Trading/Drilling Report


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



London: 27 April 2012 - ECR Minerals plc is pleased to provide the following update on ongoing drilling at the El Abra prospect within the Company’s Sierra de las Minas gold project area in La Rioja Province, Argentina.

The current drilling programme has been designed to ascertain the extent to which high grade quartz vein hosted gold mineralisation identified at surface at El Abra extends to depth down dip over a strike length of approximately 500m.



  • Assay results received in respect of 7 drill holes
  • Extension of high grade gold mineralisation to depth confirmed
  • Best intersection 3.0m in hole 2 grading 21.5 g/t gold including 1.0m at 50 g/t gold
  • Drilling continuing and further assays pending


Assay results in respect of gold mineralisation intersected by 5 holes of the current drilling programme are disclosed in the table below. The results have been received from the internationally accredited AcmeLabs laboratory in Mendoza, Argentina. Depths and intervals given are downhole.


Hole number Interval

1 0.85 0.25 81.05 81.9 94.5 45
2 (1st intersection) 0.5 4.8 96.0 95.5 116.5 55

6 0.5 3.75 45.2 45.7 104.3 55
7 No significant results 67.1 65
8 No significant results 65.0 45


Significant alteration and mineralisation has been identified visually in all holes completed so far. To date 8 of 12 planned holes have been completed. The assay results received have confirmed the intersection of significant gold mineralisation in holes 1, 2, 3, 5 and 6. No significant gold mineralisation was intersected in holes 7 and 8. Assays are pending in respect of hole 4 and certain other information regarding this hole is included in the table above.

Drilling at El Abra recommenced on 26 April 2012 having paused for approximately 2 weeks while spare parts were awaited following a breakdown of the drill rig. It is anticipated that the current 1,000m programme will be completed within the next 2 weeks. Core samples from the remaining holes in the programme will be submitted for assay as soon as possible. Following the conclusion of the programme a map of the El Abra prospect showing the location of each drilling station will be made available on the Company’s website.


Patrick Harford, Executive Chairman of ECR Minerals plc, comments:

“We are very encouraged by these results, which demonstrate that gold mineralisation does continue to depth at the El Abra prospect and that this mineralisation is of high grade in at least one area.

While assay results from the remaining 5 holes of the current programme are not yet available it is apparent that further drilling to follow on from this first programme is merited in order to more fully appraise the economic potential of El Abra in the context of ECR’s high grade, low tonnage production strategy. A key objective of further drilling would be to improve the Company’s understanding of the high grade zone of mineralisation intersected by hole 2 of the current programme from 99m downhole.

It is becoming increasingly clear that the gold mineralisation at El Abra is structurally and geochemically complex, and a detailed structural study along with additional surface geochemical sampling is planned and is expected to be of great value in targeting future drill holes.

However numerous identified and promising drill targets remain untested and a decision on whether to retain the drill rig presently on site after the completion of the present 1,000m programme will be made shortly.”
