The McIntosh Gold Mine is near the intersection of the Marvel Loch-Forrestania and Parker Range Roads. It is a short distance south-west of the intersection.
The mine was developed by Billy McIntosh, the second person to arrive at Parker Range after W.M. Parker discovered gold here in 1888. In 1891, McIntosh Gold Mining Company was floated in Adelaide with 80 000 capital. According to the prospectus, Billy gets nothing from the float, the entire shareholder money being used for the purchase of a battery and development. Laws at the time did not cover mis-truths made by mining companies, and there is no way Billy would have just given the mine away. Especially considering the capital was far more than what was needed to develop the mine.
The battery was purchased from the nearby Queenslander mine. It did not crush for the public, and was idle for long periods. Once the Coolgardie goldfield was announced, the mine was abandoned as miners fled to this incredibly rich field, and the battery was left to rust away.
J.W. Powell was mine manager. He struggled to get labour and materials to operate the mine even before the Coolgardie rush.
In 1912, a party of seven tributers were operating the mine. In 1918, the Golden Butterfly Company, from the Banker mine elsewhere in the district, took out a 12 month option over the mine.
Shortly after the discovery in 1889, several gold specimens were presented to the Perth Museum from the McIntosh reef, showing quartz peppered with minute specks of gold and gold flakes. These will be hidden somewhere in the bowels of the museum warehouse with the 30 000 other specimens it owns, and that the public have never seen.
The site covers two major shear zones, 1 kilometre and 0.4 kilometres west of the Parker Range banded iron formation horizon. The western line covers the historic mines called Searchlight, Ripper (Piemonte), McIntosh and Garibaldi. The main mine on the eastern line was called LSD. Production records from McIntosh were not recorded. Most of the work was down to 26 metres below the surface which marked the water level and limit of oxidation.
