Point Location Description: West end of area A stripping marked on a 1990 trench map
Location Method: Field Visit with GPS
Access Description: Easy access to the property is via a series of logging roads from the main haul road linking Sultan - Ramsay - Highway 144. From this Main Haul Road the turn-offs to be taken are the Blamey Road for 7km then the Cunningham Road. The Cunningham road goes north for about 8km where it splits into a crude T-junction running East West. From this point the trenches are a couple of kilometres further north along a base line and a series of trails from an old exploration camp off the eastern T-junction. Alternatively drill trails come in from the north via the old fire tower.

Dec 07, 2005 (S Fumerton) - Differential movement along the argillaceous beds is not as conspicuous as at the main showing whereas the fracturing due to faulting is as strong. Two main fault trends are present, an east west trend including the 'Joubin Fault' and a southeast trend associated with brecciation.

Dec 07, 2005 (A Wilson) - Mineralization is confined to a series of banded iron formation within a sequence of mafic to felsic metavolcanics. The entire package has been overturned with the mafic metavolcanics structurally beneath the iron formation and felsic metavolcanics above. The iron formation has been divided into two main units. The Upper Chert has thicker chert beds and consists of chert conglomerates. The Lower Chert consists of a mixture of lithologies. At the showing, felsic metavolcanics structurally overlie the chert horizons, but are intercalated with the chert along strike. These felsic rocks are primarliy tuffaceous with banded crystal, lapilli and breccia tuffs being present together with some local flows. Chloritic and sericitic alteration is present in the matrix of these tuffs. The mafic metavolcanics (lower diorite) is fine to coarse grained and has a tholeiitic affinity. The whole sequence has been intruded by an irregular plug of diorite called the digestive diorite.

Dec 07, 2005 (S Fumerton) - Various interpretations have been advanced to explain the mineralization including 1) a chemical sedimentary origin distal from any base metal source, 2) a sedimentary - exhalative model proximal to a volcanic source, and 3) a primary sedimentary origin remobilised during regional tectonism and metamorphism associated with the emplacement of various dykes. This debate is a result of various features characteristic of each process which include fine grained graded sulphide beds, coarse grained subhedral sulphides along fractures, massive sulphide veins etc. These features also have a major impact on the uneven grade of the known mineralization. In a zone adjacent to a felsic dyke there are a number of massive galena trails and veins where the dykes cut through the argillaceous and sulphide horizons.
