Solstice Minerals (ASX:SLS) said phase one reverse circulation drilling at its wholly-owned Nanadie copper-gold project in Western Australia confirmed significant growth potential at the project, according to a Tuesday Australian bourse filing.

Two step-out holes demonstrated that the deposit remained open to the north, while an infill drill hole at the southern end of the deposit confirmed widespread mineral resource estimate grade copper-gold mineralization, the company said.

The company encountered intercepts of 44 meters at 0.5% grade of copper and 0.23 grams-per-tonne (g/t) grade of gold from 146 meters as well as 33 meters at 0.4% grade of copper and 0.11 g/t grade of gold from 87 meters.

The company is now designing an around 8,000-meter phase two reverse circulation drilling program, per the filing.

Solstice Minerals' shares rose 15% in recent trading on Tuesday.
