Point Location Description: Collar of drill hole 65-10.
Location Method: Data Compilation
Access Description: Access to the area is difficult an is probably best achieved via the Hellyer main road that extends south-southwest from Highway 101 into Crockett tp, 3 km south of the drill hole. From this road there are a number of tertiary logging roads that come to within a kilometre of the drill set-up.
1964: Keevil Mining Company - ground geophysical surveys, diamond drilling.

Dec 07, 2005 (A Wilson) - A suite of high metamorphic grade gneisses occur in the area. They have been derived from granitic rocks, possible arenaceous metasediments and mafic metasedimentary rocks. The gneisses derived from granitic rocks are medium to coarse grained, have a strong foliation defined by trails of 5-10% hornblende, together with minor garnet (1-3 mm) and contain orientated xenoliths. The xenoliths range in composition from coarse massive hornblende to digested diorite. The gneisses possibly derived from arenaceous metasediments have a strong banding with development of a nebulous or pegmatitic neosome. The paleosome is typically finer grained and low concentrations of mafic minerals (biotite and hornblende) occur in thin lamellae. The gneisses derived from mafic volcanics are highly variable and the dark green hornblend forms between 20 and 90% of the rock. Where the mafic content is lower, the gneiss can be layered with variable concentrations of hornblende and garnet tending to be concentrated in certain layers. These layers range between 1 and 40 cm thick. Rusty staining due to the presence of sulphides is also restricted to certain layers within the hornblende gneisses.

Dec 07, 2005 (A Wilson) - Mineralization is hosted in a banded garnetiferous, biotite, hornblende geniss with some narrow pegmatite phases. The mineralization consists of 15-20% disseminated pyrrhotite and massive strigers of pyrrhotite up to 3 cm wide. Some pyrite and chalcopyrite is associated wit the pyrrhotite. A single assay returned values of 0.01% Cu.
