The Aspacia Gold Mine was a late arrival on the scene at Menzies. It was first pegged in November 1935 by Lorenzo Bona, Matteo Bedola, Bortolo Bedola, and Lorenzo Pieen, as 21 acres called the Aspacia.
Crushings began appearing through the Lady Harriet mill from 1939, after the lease was re-pegged. This time by John Tonta, Fausta Bona, Lorenzo Bona, and Pietro Marchetti. GML 5703Z. 24 acres.
An exemption was granted in 1942, when they all joined the Australian army. They resumed mining in July 1946 after returning. The lease was re-pegged again in November 1946. This was for Tonta, the Bonas, and now G. Marriotti. The lease contained a two compartment shaft down to 350 feet, on a semi sulphide lode containing quartz stringers 70 feet long and 2 feet wide. Crushings were noted until 1948.
Yet again, January 1948, the lease was re-pegged by much the same crowd of Giovanni Marriatti (probably same as above), John Tonta, Lorenzo Bona, Fausta Bona, and Petro (Pietro?) Marchetti. 12 acres. No crushings could be found past 1948.
This period from the 1930's to 1940's saw 9313 tonnes of ore extracted at 35.7 g/t yielding 10 731 ounces of gold. The source states the remaining resource is 19 000 tonnes of ore at 3.27 g/t yielding 2000 ounces of gold.
The mine is 500 metres west of the First Hit open pit, on the western edge of the goldfield, in turn about 1 kilometre west of Menzies. It is less than 50 metres north of the Menzies-Riverina Road, consisting of the shaft remains, and small mullock piles.
It is a south-west plunging deposit, within amphibolite rocks, and consists of quartz veining up to 2 metres thick, with a small envelope. Pyrite and arsenopyrite are the dominant minerals, with some chalcopyrite, galena, and sphalerite.
