ECU Silver Opens New Mining Unit Along Major Vein
Thursday September 16, 2010, 10:00 am
TORONTO, ONTARIO--(Marketwire - Sept. 16, 2010) - ECU Silver Mining Inc. (TSX:ECU; OTC:ECUXF - News) is pleased to report on results from a new mining unit on the western extension of the Terneras vein located within the Velardena Property. This section of the Terneras Vein, which is host to reported "inferred" resources, has been opened and successfully developed. The average gold grades, in the section opened to date, are approximately 500% higher than the grades for the corresponding resource block used in the calculation of the Company's National Instrument 43-101 mineral resource estimate. (my bolding for emphasis)
The current underground development completed by ECU has opened the western extension of the Terneras vein over a length, to date, of 60 metres (197 feet) with 18 cuts yielding average grades of 3.55 grams per tonne (g/t) gold (Au), 84 g/t silver (Ag), 0.82% lead (Pb) and 1.52% zinc (Zn) over a width of 1.15 metres (3.77 feet). The grades in the cuts increased westerly along the drift with the best result yielding 27.19 g/t Au, 66 g/t Ag, 6.99% Pb and 8.10% Zn over a width of 0.80 metres (2.62 feet).
In the last couple of months, ECU has opened workings in this area which had been interpreted as the western lateral extension of the Terneras vein. That interpretation was originally based on surface sampling, geological interpretation and a cut in drill hole BV-07-04 (press release dated August 29, 2007) that returned assays of 2.30 g/t Au, 3,130 g/t Ag, 15.4% Pb and 1.16% Zn over 0.40 metres (1.31 feet). The interpretation suggested that the Terneras vein had been displaced 150 metres (492 feet) to the south and could be followed laterally for another 700 metres (2,297 feet) to the west.
Michel Roy, Chairman and CEO of ECU stated, "The Terneras vein is one of the largest in the area and our work suggests this section of the vein continues for almost three quarters of a kilometre, which will make this area a very important mining unit for us. As witnessed in the Terneras vein, we are seeing a trend where we have opened several areas which contain mineral resources that are classified as inferred yet we have been successfully treating this material in our mills."
The Terneras mine was the most important mine of the Velardena district over 100 years ago. From its inception in the late 1800's to its closing in 1922, it is estimated that over 1,700,000 tonnes were extracted and processed, from this vein alone, at the local smelter owned by Asarco Mining. The mine closed at the beginning of the Mexican revolution for security reasons.
In those days, the Terneras vein was opened laterally over a length of 1,200 metres (3,937 feet) and a height of 630 metres (2,067 feet). The lateral limits of the workings corresponded to regional faults that displaced the east and west extensions which were not found in those days. Work done by ECU since 1997, has found both lateral extensions as well as demonstrated the continuity at depth.
Stephen Altmann, President of ECU also stated, "We are pleased to see that our Velardena Property continues to show examples of strong vein continuity, particularly within previously identified inferred mineral resources. Furthermore, in the case of Terneras, adding a new mining unit, that is independent from the other three mining units currently in operation, adds to the flexibility of our general mine plan and brings us closer to our target of mining sufficient mineralized material to fill both mills to nominal capacity before year end."
Cautionary Statements
Readers are cautioned that until a prefeasibility study is completed, there are no assurances these latest mineralized zones will be economically viable.
All widths are true widths. Samples were assayed at the ERSA laboratory in Torreon, Coahuila, Mexico which is currently in the process of being certified. Mr. Michel Roy, P. Geo., a "qualified person" within the meaning of NI 43-101, prepared the technical information disclosed in this news release.
