About
The mine produced over 150,000 ounces of gold at 15.9 grams/tonne in the period 1934 to 1944 and is north of the
Mining records indicate that the high-grade shoots were developed within stratabound veins on the limbs and closures of pre-existing folds. Individual lodes were mined over a strike length extending up to 200m and to depths of 155m below surface. The shoots are up to 10m wide and 30 to 70m long and were best developed in the Main and East Lobes. The mine lease and surrounding areas are considered to have good exploration potential for the discovery of additional high-grade shoots. The shear zones were reported as zones of complex deformation with strongly developed foliation and quartz-carbonate veining. None are well exposed at surface.
Some amphibolite rocks within the shear zones have been altered to biotite schist and the gold bearing quartz veins within the shear zones are weakly sulphidic. Gold was said to be associated with pyrite-arsenopyrite and/or chalcopyrite-pyrrhotite mineralisation. Mine workings on the Main Lode comprise an open pit to a depth of about 20m and underground drives and stopes down to the 4th Level at 90m depth. Some stopes were up to 10m wide but were generally between 2m and 5m wide. The lode strikes N-S over most of its length and dips steeply to the east. It was mined over a strike length of about 200m. Mine records show that within the broader lode, a small high-grade shoot which plunges to the south at 40 to 50 degrees is coincident with thickened parasitic fold on the east limb. The Main Lode was best developed between 15 and 60m vertical depth (Levels 1 and 3) and widest at approximately 30m vertical depth (Level 2). The East Lode was discovered following underground drilling from the Main Lode workings, and subsequently developed over six levels to a total vertical depth of approximately 155m. Stopes were from 2 to 10m wide and generally around 5m wide. The lode strikes NNE and dips steeply to the west. The best mineralisation is developed around a parasitic fold on the eastern limb of a north-plunging synform, and close to the closure of this structure. The lode was mined to surface in a steeply north-plunging shoot but in the deeper levels the plunge flattens markedly as it tracks northward along the closure of the synform. At the cessation of mining on the 6th Level the shoot was becoming sub-horizontal. West Lode and New Lode are linked by development from the Mt Palmer shaft at the 2nd Level. The New Lode consists of two lodes approximately 10m apart, which have been interpreted to form an anticlinal fold closure close to the present-day land surface. The fold is interpreted to plunge to the north. The New Lode has been mined over a strike length of 50m to a depth of 30m. The stopes are 2-3m wide and open to the surface. The lodes strike NNE and NE and both dip steeply to the east. The open pit is inaccessible due to steep walls and unstable ground and the stopes below the pit floor are filled with water. The West Lode was mined over a strike length of about 40m to a depth of 30m. The reported stopes are about 2m wide but do not reach the surface as the lode is reported to have pinched out 5m below surface. The lode strikes N-S but swings to the SW at its southern end and dips steeply to the east. Historical exploration programmes at
