The first note found was 1891, stating a prospector by the name of McKenzie (surname) had discovered a reef, and was applying for a reward lease. Crushings were not found until early 1896 by D. Richardson.
Later in 1896 a local syndicate called the North West Australian Goldfields Mines took over, constructing a battery some distance away on the Nullagine River. Regular crushings for gold was then found by the company across 1897. The battery initially was only working five hours a day due to a lack of water, although it is later stated this problem had been overcome. It lacked a cyanide plant. Jason Isdell is mine manager. Several tunnels had been driven into the hill.
March 1896, 32 diamonds were recovered from the battery boxes, the largest half a carat. 30 more were found a month later. July 1897, 16 small diamonds were found in the battery boxes, the largest again half a carat. Spiro Achimovich, South African diamond expert arrived later in 1898 for the Lady Forrest syndicate and found several more diamonds at Barney's Hill.
The mine is one of several one to two kilometres north north-west of the Nullagine town site. Information relating to other mines would indicate it was at the southern end of the field, just north of the Grant's Hill Mindat locality. The area is heavily disturbed by bulldozing from the activities of modern exploration and mining companies. Map approximate only.
