Dec 07, 2005 (S Fumerton) - The chlorite schist fragments on the muck pile vary between having a week foliation to a very strong 'polished' foliation with a crenulation cleavage. This schist represents an extreme phase derived from the diorites and granodiorites. Intermediate phases include the porphyroclastic quartz diorite which may or may not have a strong flaser texture.

Dec 07, 2005 (S Fumerton) - The mineralization is located in an altered shear zone that cuts quartz dioritic and granodioritic rocks of the Chester Granitoid Complex. There are various phases present including:- 1) medium to coarse grained hornblende diorites - quartz diorites with some limited development of feldspar porphyroblasts, 2) some very coarse grained, quartz rich granodiorites with conspicuous blue quartz grains (<4mm) and a matrix enriched in chlorite, 3) a cataclastic rock derived from the granodiorites which contains a dark chloritic matric and angular, blue quartz porphyroclasts, and 4) a chlorite schist. There are also a number of small felsic dykes cutting the quartz dioritic phases. Locally the biotite alteration and to a lesser extent the chlorite carbonate alteration in the shear zones is intense enough to result in a schistose appearance to the rocks.

Oct 28, 2013 (S Fumerton) - Chalcopyrite with lesser pyrite occurs in semi continuous trails up to 3mm thick and disseminated in various rocks. Sulphides form up to 2% of the rock locally. Mineralized rocks include the coarse grained quartz rich phases of the granitoid complex associated with chlorite alteration and the various cataclastic rocks derived from the granitoid rocks.There is a correlation between the intensity of alteration in the shear zones and the grade of gold mineralization. Little vein material is apparent in the muck piles and on surface. However, a number of pieces of muck contain short quartz and quartz/carbonate veins hosted in the chlorite schist. Otherwise what little veining is left consists of a very fine grained, banded, grey to milky white quartz with common chalcopyrite grains disseminated throughout. Chalcopyrite also occurs in cross fractures within the quartz vein and in thin veinlets in the adjacent wall rock which parallel the quartz vein.
Dec 07, 2005 (A Wilson) - Sampling by Ironside et al in 1934 returned values of 6.5 g/t Au over 1.4m in channel samples and values up to 42 g/t Au from grab samples. The average reported grade underground in 1937 was 29 g/t au over 0.7 m. Results from underground sampling in 1947 ranged between 0.3 g/t and 35 g/t Au in channel samples. The average grade of the bulk sample collected in 1979 was 30 g/t Au across 0.9 m for 60m.

Notes: A brief visit to the shaft area was made and the author was met by Norbert Reinhart who was in the process of replacing the old timber cap on the shaft with a concrete cap. (This was completed by October 12th). The timbers in the shaft are in good order and the inclined steel headframe is intact though the hoist rope has been removed. Similarly the hoisting room, which contains an old compressed air hoist, is intact but the compressor has been removed. Other buildings on site are in ruins and some old underground carts are scattered around the headframe. In some exploration reports there is mention that the old trenches were filled in. This is not the case as just west of the shaft there is a 3 to 4m deep open cut with a fence at the east end adjacent to the shaft. This open cut is covered in vegetation debris.
