Infinity Lithium (ASX:INF) will start drill-testing the CST gold-silver prospect within the Cobungra project in Victoria in July, according to a Thursday filing with the Australian bourse.

The prospect will undergo a first-pass drilling campaign to identify additional priority targets and areas of geological interest, the filing said.

The company is awaiting the mobilization of a diamond drill rig, expected to arrive within four to five weeks, per the filing.
