Point Location Description: South end of the Main Trench where the stream flows over the iron formation.
Location Method: Field Visit with GPS
Access Description: Relatively easy access is possible from the main Sultan Access Road. This is done by initially taking the Blamey Access road 7km to the Cunningham Access road and then driving another 8km to the northern T-junction just south of the property. The west T-junction is a circuitous logging trail which goes clockwise to join up with the old road from the fire tower to the Main Showing. The final section of this road is not passable with a truck under normal circumstances. Alternatively, from the old drill camp which is in a hollow off the Eastern T-junction there is a good base line extending north to the showing.

Metamorphism Type: Regional
Metamorphism Grade: Greenschist
Dec 07, 2005 (S Fumerton) - Schists with local drag folds occur preferentially in the argillaceous and sulphide rich horizons within the iron formation. It is suspected that this deformation is a result of differential movement during regional folding being accommodated in the less competent rocks. In addition two main younger fault trends have been documented, an East West trend which includes the Joubin fault, and a southeast trend associated with brecciation. The east west trending faults generally dip moderately to the south and have off-set the primary stratigraphy and locally cut off the lateral limits of the mineralization. The main fault in this set, which has been called the Joubin Fault, effectively has separated the Main showing from the South Zone. Adjacent to the fault, some sericitic alteration has been noted within the metavolcanic units. Common feldspar porphyry dykes have a similar strike but dip sub-vertically. The southeast trending faults are near vertical and have associated chlorite pyrrhotite alteration in brecciated zones.

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) - There has been considerable debate as to whether the mineralization is essentially a primary sedimentary deposit, a hydrothermal deposit controlled by the intersection of faults with banded iron formations, or the remobilisation of primary mineralization during regional folding and faulting. This debate is due to elements of all styles existing. It has been concluded that six types of mineralization occur:- 1) Horizons of banded coarse grained, massive pyrite/pyrrhotite with sphalerite and chalcopyrite associated with banded iron formations.? primary mineralization recrystallized during tectonism. 2) Fine grained disseminated to semi-massive sphalerite and pyrite in argillaceous chert horizons which may be primary mineralization. 3) 'Chert Breccia Zones' with chlorite, chalcopyrite, pyrite, sphalerite, and galena which may be remobilised sulphides forming veins during tectonism. 4) Chloritic volcanic - argillite - sulphide breccia with mineralized joints carrying chalcopyrite, sphalerite and galena. 5) Chloritic argillite - pyrite horizons with chalcopyrite and sphalerite replacing pyrite for short distance laterally. 6) Late east west quartz carbonate veins associated with alteration which carry pyrite, galena, sphalerite, and chalcopyrite. Bornite is an additional mineral that occurs locally were mineralization has been recrystallized during tectonism. On a large deposit scale there is some zoning to the mineralization. This zoning is characterised by copper enrichment in the structurally lower beds and in the centre of the deposit. In turn the copper gives way progressively to zinc enrichment, then iron enrichment in the upper horizons and lateral margins. Similar zonations occur in individual beds. Mineralogical zoning is also apparent as pyrite is the dominant iron sulphide in the Lower Cherts where as pyrrhotite dominates in the Upper Cherts.

Geologist: W Savage
Notes: A second visit was made to the Shunsby property. During the year which has elapsed since we visited the property in 956 the value of copper, lead, and zinc in the world markets steadily deteriorated. As a result there was nobody at this time working on the mining claims in the Cunningham area except a prospecting party under the direction of Martin Shunsby. He was able to show the writer several newly discovered and interesting zones of mineralization on the outlying claims. The previous fall, after Nipiron had withdrawn, additional finances were made available to Shunsby Mines by a syndicate of mining companies which appointed Teck Exploration to direct further investigations. Another 5600' of drilling in 17 holes was done. Three of these holes were drilled in the 'copper zone' where the Nipiron drilling had been concentrated and Teck estimated that it contained 152,000 tons grading 1.35% Cu, 1.22% Zn. Most of the new drilling was done one claim to the south and a number of holes intersected mineable widths of up to 6% Zn. [ PRECIS ]
Date: Jun 01, 1993
Geologist: S Fumerton
Notes: A visit was made to examine the property following the past winters drill program. The old camp site by Hiram Lake is in ruins and both cabins are uninhabitable. Most of the old core racks have partially collapsed though some boxes have been relabelled. Probably during the recent work by MPH. Core from the recent drilling by Phelps Dodge has been stacked in a crib at the old camp site.
