The Hope's Hill Gold Mine is approximately 2 kilometres north of Southern Cross, and 500 metres west of the Southern Cross-BullFinch Road, and just north of the southern limit of the Lake Koorkoordine salt-pan. It contains a long narrow, 90 metre deep, and partially re-filled north north-west trending open pit, with two large earth encased mullock plateaus to the east.
The mine was one of the first in the Southern Cross area, discovered by Macpherson (surname) around 1888. He named it the Caledonian, everyone else called it Hope's Hill. The name refers to the Hope's Hill Gold Mine from the early 1890's, then refers to an area containing several named prospecting leases from 1900 to 1910, before being called Hope's Hill Gold Mine again from the late 1980's until modern production stopped in the early 1990's.
Modern production achieved 220 000 ounces from the shallow open pit, averaging between 2.0 to 8.05 g/t.
We have an early description of the surface of the deposit less than one year after discovery. It was a bold 50 foot wide outcrop of white quartz, with a cutting, and 50 foot deep shaft at the top of the hill. The lode strikes north north-west and dips slightly west. The Hanging Wall side is white quartz and quartose sandstone, with irregular slate and grit banding. The Footwall side is ferruginuous quartz with 4 to 6 feet of soft carbonaceous clay rich in fine gold.
The Hopes Hill Gold Mining Company is noted as employing 20 to 30 men in 1897. A 40 head battery and an extensive plant was erected by the end of 1899. At face value it appears to be an overstatement for the amount of gold available. By 1901, its reported the company had abandoned mining on the lease.
From this time to at least 1910, several prospectors operated small leases in the area. This may have continued in later times, but no information was found.
