All holes encountered moderately to strongly altered skarn zones, according to Alta Vista's statement. Six holes, totaling 577 metres, were drilled to investigate the continuity and extent of skarn mineralization found in surface trenches and outcrop.
The company said drilling tested a target area of 875 metres in length, with a total of 400 samples sent for analysis. Core samples ranged in length from 0.5 to 2 metres, while values were as high as 0.288 grams per tonne (g/t) gold, 9.2 g/t silver, 2.39% copper, 0.1% lead and 1.06% zinc.
The widest intervals found 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.
The company is now in the process of correlating surface data with the drill results, Alta Vista said.
Alta Vista, in common with other explorers, identifies and acquires properties that it feels exhibit high potential, and then compiles data and performs first pass confirmatory exploration, advancing its assets – ideally to drill-ready stage. From here, it deviates from the common path of junior explorers by bringing in a partner that earns an interest in the project by providing funding for further exploration.
The Carol property is located about 4 km from the Piedras Verdes porphyry deposit, Mexico's third largest copper producer at more than 70 million pounds per year.
In late May, the company received approval from the TSX Venture Exchange for its $300,000 private placement financing, the proceeds of which will be used for general working capital and its portfolio of projects.
