After the failure to find payable gold at the neighbouring Flemings Reef, landowner Malcom Fleming sold the property to George Muir in 1918. He employed experienced prospector, Robert Worth, who discovered another auriferous reef to the north (north of the No. 4 Road). It was named Muirs Reef. It was worked from 1920 to 1928, said to have produced 1299 kg Au and 385 kg Ag.
The area is said to contain several adits and the foundations of a 10 head stamp battery, however it is on private property, and partly altered by grazing and kiwifruit production. Glass Earth Ltd explored the site 2009-2013, finding a 2 metre long high grade section of reef. It is an epithermal reef of quartz and adularia in the Coromandel andesite.
