Solstice Minerals (ASX:SLS) said that geological work identified significant resource extension drill targets at its Nanadie copper-gold project in Western Australia, according to a Thursday Australian bourse filing.

Systematic relogging of historical drill holes and structural interpretation helped identify the targets, supported by both induced polarization and aeromagnetic surveys.

It is preparing a reverse circulation drilling campaign to test the targets.

Its shares rose 5% on market close.
