Dec 07, 2005 (S Fumerton) - The mineralization is hosted in a shear zone located on the contact between a diorite and highly strained epiclastic sediments. There are some small scale crenulation folds in the shear zone.

Dec 07, 2005 (S Fumerton) - The diorite on the south side of the shaft is a medium grained massive unit. Pervasive saussuritization occurs in the unit and there is a foliation developed near the sheared contact. The epiclastic unit to the north is highly strained and schistose though probably derived from arenites and conglomerates. The schistosity is due to the high sericite content and fine grained recrystallization. Strong brown carbonate alteration occurs in the sheared contact zone between the two main units.

Dec 07, 2005 (S Fumerton) - There is a trace of pyrite together ilmenite disseminated within the quartz, carbonate, chlorite knots. These knots are locally up to 30cm thick and have a short strike length. Though generally there are two sets of quartz veining the altered zone. The boudinaged and rotated quartz veins which are typically less than 3cm thick but do develop into larger knots. Secondly discordant en-echelon extension veins up to 1cm thick and 20cm long. The carbonate altered shear zone can be traced over 20m in the recent trenching.
Jun 29, 2016 (A Wilson) - Values of 4 g/t Au were reportedly returned from the vein in 1910. Samples collected from the Moore shaft allegedly returned values of 0.5 g/t Au (1939). Average assays for samples collected along strike of the mineralized zone were between 1.98 and 24 g/t Au (1979). Assays from a sheared diorite at the shaft (collected in 1987) returned values of 2.7 g/t Au over 4 m.
Jun 12, 2013 (P Bousquet) - A sample, 522122, taken from a trench consisting of light grey or light green-grey altered mafic rocks returned an assay of 2.81 g/t Au (T-5852).

Geologist: S Fumerton
Notes: There are a number of areas that have been stripped recently along the strike extension of the altered shear zone. This stripping has exposed similar altered shear zones concentrated on the diorite - epiclastic sediment contact. However, there is a paucity of quartz veining associated with the shear zones.
