ECU Silver Mining has exposed the upward continuity of many mineralized layers called the A vein package, through the current underground development. These veins were separately explored at level 17 and are now exploring at the lower 18 and 19 levels.
The veins were irregularly mined at the upper levels from 14 to 17. The height of the active mining region is 260 m in total. The upward continuity of the A veins package is 300 m.
There is a 100 m section in the block established by the A veins package, where the veins are located closer and can be mined. The average thickness of the vein sections in the levels 12 and 19 is 35 m, which represents a volume of over 3,000,000 t of mineralized material in 260 m.
The company recently identified the upward expansion of the A veins package data when the system was found during a new ramp drive at the level 12. It has intersected 1.18 g/t gold, 0.31% copper, 307 g/t silver, 0.33% lead and 0.36% zinc over 24 m at the A veins package.
In addition, ECU is advancing the deep drill hole under the Santa Juana mine and has currently penetrated the target zone under the immense sulphide that was cut initially in the SJ-18-21 drill hole. The drill has cut 200 m under the planned outcrop of the huge sulphide zone found on the top. Mineralization was identified for more than 20 m of core length. This mineralization seems to be a replication of the difference in the mineralized A4 vein intercepts, above 1,200 m. The mineralization differs from the huge sulfides to the calcite and sulfides mixture in the upper A4 vein levels.
The Chairman and CEO of ECU Silver Mining, has commented that a strong mineralization similarity exists in the initial daughter hole when compared to the mineralized material explored above 1,200 m.
The company had signed a merger agreement with Golden Minerals to form a new junior precious metals mining firm, during June 2011.
