Andean Silver (ASX:ASL) continued advancing exploration at its Cerro Bayo project in Chile during the March quarter, confirming the prospectivity of newly identified mineralized vein systems, according to a Wednesday filing with the Australian bourse.

The company generated "outstanding" drilling results in key areas, with conversion drilling consistently intersecting main mineralized zones in Coyita, Delia SE, and Temer, the filing said.

Results will be integrated into an updated mineral resource estimate slated for release in the June quarter, per the filing.

Shares rose nearly 1% in afternoon trade Wednesday.
