Liberty Silver Corp has begun its drilling programme on the Trinity Silver property located in Nevada, US.

Boart Longyear has been appointed as the contract driller to undertake the drilling programme, planned for up to 7,000m.

Liberty Silver Corp President and COO Bill Tafuri said that the drilling programme will help the company understand the significant resource potential contained in the Trinity property. "The historic data and new geophysical surveys on the Trinity property will enable us to be more effective with our drilling, mitigate drilling risk and allow us to better control costs."

The prospect comprises of a formerly productive open pit silver mine, called the Trinity Mine, which was operated by US Borax and has been shut since 1989.

The mine produced approximately 5Moz of silver from 1.1Mt of oxide ore, at a grade of 6oz/t of silver, using heap leach technology.

The company has assay data from over 400 historic drill holes, including data from over 100 drill holes outside the Trinity mine resource area. Liberty has integrated the historic geophysical surveys and a recently completed magnetotelluric survey, which can be used to identify high-priority targets.

The first phase of drilling will be on extensions from the original pit to confirm the continuity of mineralisation identified by historic drilling and to define the extent of the resource. The company said that the previous drill holes revealed silver, lead and zinc mineralisation at depths of up to 150m, and that the deposit is still open at depth.

Liberty also intends to begin geophysical surveys on three of the six identified silver targets during the course of the first drilling phase.
