Located at Porcupine Flat which was once a flourishing area of the Maldon goldfields,
a dredge and dragline operation was developed in 1958 that represented that phase of
gold mining in Maldon when technology enabled relatively large scale reworking of earlier
deposits which had first been worked by thousands of individual prospectors in the rush of the 1850s.

The dredge originally worked to the north of it's current site, the existing dam being constructed when the Porcupine Flat Gold Treatment Works were constructed over the original workings.
The dragline standing on the bank of the dam was brought from the Yallourn Coal Mine to assist in creating the initial dam and the ongoing operation. It proved to be of little value and was
abandoned in it's present position early in the operation.
