The Peach Tree was a late starter on the goldfield, discovered and initially developed by J. Crabtree and S. Bomm from 1907. They sold the lease for 250 pounds to Elliot and Saunders. For some reason, even though they were milling 30 dwt ore, profits barely covered expenses, and they ceased working the mine late 1912.

A. Thomas successfully applied for forfeiture of the lease early 1913. He took in a mining partner, Peter Brand, who sold his interest shortly after for 10 pounds to D. Thomas, brother to A. Thomas. D. Thomas had been active at Metzke's Find. Active mining was found by the Thomas' until the end of 1914.

The shoot was 100 feet long, 6 to 18 inches wide in diorite. This may refer to the central bar described by modern exploration.

Across 1993 to 1994, Pancontinental Mining developed a shallow pit, mining lateritic gold and Fe enriched ore. The site has now been rehabilitated. It is approximately 2 kilometres south of the Evanston-Mulline and Davyhurst-Mulline road junction, and just west of the latter road. The Mulline cemetery is between the mine and the road.

Peach Tree is a small lateritic regolith gold deposit, with no known primary mineralisation underneath, and is thought to be transported gold from elsewhere on the goldfield. Gold is hosted by lateritic gravels and duricrust which contain soil based carbonates in the upper 2 metres. The gold enrichment follows an east-west trend, with well defined south and west boundaries. To the south is saprolite and west fresh rock. Before mining the lateritic material formed a low mound.

Within this deposit was a massive bar of strongly induriated carbonate, striking east-west along the axis of the deposit. Gold values decreased the further from this bar. The regolith contained clays, loams (orange rich brown to red), Fe oxide enrichment, calcrete pisoliths and nodules. Gold enrichment in these deposits is the result of warm humid conditions during the Tertiary period, followed by the present arid period, and the influence of acid and saline groundwaters.
