An underground sampling program has been completed on Exall Resources’ (TSE) La Verde Grande property in Sonora, Mexico.
Sampling on the upper level of the old mine returned values of 1.13% copper, 3.42% zinc, 0.12 grams gold per tonne and 71 grams silver across 18 metres. On the main level, sampling yielded 2.17% copper, 0.38% zinc, 0.19 grams gold and 88 grams silver over 26.4 metres. At the lower level, the mineralized structure contained 2.05% copper, 2.55% zinc, 0.1 grams gold and 10 grams silver across 15.9 metres. About 12 metres separate the three levels. Based on the encouraging results, the company plans to initiate a drill program immediately.
In other news, mining engineering firm Kilburn has been contracted to complete a feasibility study on Exall’s Santo Tomas copper-gold porphyry project in Sinaloa, Mexico. The study is intended to confirm the viability of solvent extraction-electro-winning for processing copper oxide ores. Exall also has an agreement with American Barrick Resources (TSE) to seek gold projects for joint venture in Mexico.
