Solstice Minerals (ASX:SLS) said preparations are underway for imminent additional infill and step-out aircore drilling at the Edjudina Range discovery, within the Yarri gold project in Western Australia, according to a Monday Australian bourse filing.

The infill aircore drilling is designed to selectively assess the orientation of gold-bearing structures through scissor drilling in key locations and to also conduct step-out exploration beyond the northern limits of drilling.

Its shares rose 5% in recent trading on Monday, reaching their all-time high.
