Alta Vista Ventures Ltd. (AVV-TSX-V) is pleased to announce that its optionee, Tosca Mining, has released analytical results from their recently completed drill program on the Carol Copper project, located in Sonora, Mexico.
Six drill holes, totaling of 577 metres, were drilled to investigate the continuity and extent of skarn mineralization encountered in surface trenches and outcrop. Drilling tested a target area measuring 875 metres in length.
All holes encountered moderately to strongly altered skarn zones. The Company is in the process of correlating surface data with the drill results.
A total of 400 samples (including blanks and standards) were sent for analysis with core samples ranging in length from 0.5 to 2 metres. Values received ranged from trace to 0.288 g/t gold, trace to 9.2 g/t silver, trace to 2.39% copper, trace to 0.10 % lead and trace to 1.06 % zinc.
In general, mineralization is localized over narrow widths. The widest intervals encountered in core were from hole 5, which intersected 0.98 % zinc over 2 metres from 6 to 8 metres depth and 0.29 % copper over 3 metres from 26 to 29 metres depth.
Fracture controlled mineralization combined with geochemistry indicates that the skarn formation was subjected to significant leaching and subsequent remobilization that has resulted in the copper/silver/gold/lead/zinc mineralization being concentrated in a zone at or near surface. The controls on the location of the higher grade mineralization intersected in the trenches remains to be fully understood.
Samples from Carol were prepared and analyzed by IPL Inspectorate in their facilities in Mexico and Vancouver, respectively. Samples generally consisted of 1-3 kg of material. Gold, silver, copper, lead and zinc were analyzed as part of a multi-element ICP package using an aqua regia digestion. Over limit samples with greater than 1% Cu, Pb and Zn were re-analyzed using ore grade detection limits.
