A former small mine located within the Thumb Creek State Forest.
Worked via adits.

While Gilligan et.al. indicates that this mine is 22km by road from Taylor's Arm, it is closer to Thumb Creek.

This mine and others in the area are located in what is also known as the “Taylor’s Arm Antimony Province”. This terminology appears on many geological maps.

The mines in the area are approximately 30-40kms west of Macksville and to the immediate east andwest of the Taylor’s Arm River.
