The Caroline gold mine is located on a parallel structure or splay shear from the Mary Lane shear zone, on a steep ridge hosting Au/Cu mineralisation. The ironstones in the area are best developed around the mine, attaining 15 x 100 feet, as hematite/magnetite quartz ironstones or hematite/magnetite stringer zones in chloritised sedimentary rock of carbonate, chlorite, or talc alteration zones. Lamprophyries crop out near the mine as flat lying sheets, with at least one intersecting the ironstone body at the mine.

Limited historic information found. The earliest dates found was 1935, with a crushing by G. Wherrett. Ben May is also noted as a part owner in 1935.

Around the same time, another source states the mine was on option for 12 000 pounds to the Euro Development Company. A shaft had been sunk to 40 feet, with a parcel crushed at 2 ounces to the tonne, and another 150 tonnes of ore ready to be processed. Total production from the mine to the end of 1935 was 1216 tonnes of ore for 163 ounces of gold. Un-named crushings were found in 1936 and 1939.

Henrietta Ruger is noted as taking out the lease in 1945 (GML 134E). There were probably several individual prospectors over the years. A 1965 source states the mine is still being operated intermittently, having produced to that time 280 ounces of gold.

The area immediately south-east of the mine was later explored by Roebuck Resources, and the Caroline mine itself by Posgold in the mid 1990's, finding very little. At this time the lease was owned by P.C. Perry.
