"El Tigre is also investigating a unique vat leach system that is being successfully operated by Dia Bras Explorations Inc. in the state of Chihuahua. This system requires the construction of several large 12 by 24 metre concrete containment areas (vats) where material is placed, leached and removed over a 5 to 7 day period. The metal rich solutions are then passed through a Merrill-Crowe precipitation circuit and silver and gold is recovered. El Tigre is retaining the same service providers as Dia Bras Explorations Inc. to assist in the evaluation, design and construction of the process facility".
