Alkane Resources Ltd has discovered a potential mine extension for the Tomingley Gold Operations in Central West New South Wales, Australia, with drilling results highlighting a steep plunge of new gold mineralisation beneath the existing San Antonio deposit.
Two drill holes encountered hits of high-grade gold beneath San Antonio’s planned open cut mine, which stretches over a 1-kilometre-long continuous strike and remains largely untested at depth.
Results included 3 metres at 1.79 g/t gold from 273 metres, 2 metres at 5.03 g/t gold from 416 metres and 6 metres at 1.37 g/t gold from 711 metres.
ALK intends to drill test several other high-grade areas for down-dip mineralisation, targeting promising host rock including andesites, monzodiorites and dacites.

Targeting fresh zones of gold
“The broader Tomingley region has many occurrences of gold mineralisation,” Alkane Resources managing director Nic Earner said.
“As well as potential mine extensions of our existing undergrounds we are doing early-stage work on identifying new mining areas.”
Drilling results of note from beneath San Antonio include:
Hole SAR003D -
- 3 metres at 1.79 g/t gold from 273 metres including 1 metre at 2.43 g/t from 274 metres;
- 2 metres at 5.03 g/t from 416 metres; and
- 1 metre at 2.98 g/t from 464 metres.
Hole SAR004D -
- 1 metre at 2.78 g/t gold from 334 metres;
- 6 metres at 1.37 g/t from 711 metres including 1 metre at 2.44 g/t from 711 metres and 1 metre at 2.34 g/t from 713 metres.
ALK has also restarted regional exploration at Tomingley for the 2025 season.
The first pass of aircore drilling will cover 17,000 metres across promising volcanic rocks and structures interpreted from drone magnetic surveys.
Alkane will then employ diamond and reverse circulation (RC) drilling rigs to test the El Paso, Tomingely Two and new targets identified by previously completed fieldwork, for about 3,200 metres of drilling.
