Open-pit gold mine.

Species not listed but likely to the similar or the same as the Granny Smith Mine which is 500 metres south. Goanna, Granny Smith and Windich Mines are all on the same lode, with a strike length of 3500 metres. While gold mineralisation is continuous along the entire length, it is only economic at the three mines. Granny Smith was discovered by Ray Smith in 1979, and after the Granny Smith Mine was abandoned around 1992, other nearby gold ore bodies were mined to feed the processing plant.

Goanna is 25 kilometres south of Laverton in the Laverton Shear Zone, of major north-south shears and associated faults.

The upper regolith is topsoil and colluvium of banded iron formations, quartz and ferruginous nodules as gravel; then a hardpan of cemented red-brown colluvium and clays; then saprolite of a weathered bedrock in red-brown clays with red-orange ochre, with veins and seggregations of calcite.

At Goanna the gold is entirely within the oxidised and weathered meta-sediments. The ore body is 800 x 50 x 8 metres, dipping 50 degrees to the east. The sediments contain banded iron formations where most of the gold is found, where they are cut obliquely by sub-parrallel shears. The shears trend north-north-west and strike for 1 kilometre, the mineralisation 5 to 20 metres thick.
