West Coast Silver (ASX:WCE) started an air core program at the Elizabeth Hill project in Western Australia to identify targets surrounding the historical mine and along the eastern Munni Munni margin, according to a Thursday filing with the Australian bourse.

The program follows completion of the second phase diamond campaign, testing near-surface mineralization, and potential deeper areas beneath historical workings, where visible native silver was intersected, with assays pending, the filing said.

The company will continue to evaluate data from within its tenement area to generate new targets, per the filing.

Shares rose 10% in afternoon trade on Thursday.
