Gold mineralisation occurs within the Beaton's Creek conglomerate.
The geological unit is the Hardey Formation with an age of approximately 2.75 billion years.
Coarse and fine gold is seemingly related to higher concentrations of pyrite within a 200 metre sequence of poorly-stratified, poorly-sorted, polymictic, pebble-to-boulder ferruginous conglomerate.
