The abandoned pits are 20 kilometres south-west of Sandstone, and about 3 kilometres south-east of the Bulchina mine, and the Sandstone-Paynes Find Road. The site contains two small abandoned open pits, and a third pit between, which appears to have been filled with mullock from the other two. At the time of writing the site also contained a small processing plant.

The northern pit is called Goat Farm, middle Eureka, and Plum Pudding is the southern pit. The site holds the CIP processing plant, built by Herald Resources before Troy Resources, and then Black Oak Minerals took over. It has been mothballed since 2010, and is called the Sandstone Mill.

Modern production commenced in 1993 by Elmina NL, producing 10 000 ounces from the Bull Oak mine laterites. In 1994 Herald Resources constructed the above processing plant, and open pit mining from Twin Shafts. Subsequent production came from the Oroya, Goat Farm, Shillington, Two Mile Hill, Plum Pudding and Bull Oak open pits until 1999. Total production was 1.9Mt at 2.0 g/t for 125 000 ounces of gold.

In 1998, Troy Resources acquired the Bulchina project from Cambrian Resources, and in 1999 purchased the CIP plant from Herald. Mining began at Bulchina and they obtained 230 000 ounces at 3.62 g/t to April 2004, when it closed. The plant continued to process low grade stockpiles and waste material at 504 000 tonnes at 1.26 g.t. Production then swung east to the Lord Henry and Lord Nelson mines until 2010 when these closed. Black Oak Minerals subsequently acquired the leases.

Black Oak Minerals in a 2015 quarterly report state the site contains 50 Kt of ore with 30 Koz of gold at 1.69 g/t. It provides no other information, and the location does not appear to be a priority.
