Wishbone Gold Plc AIM: WSBNthe London listed precious metals trading and exploration company, advises that main licence recently acquired in Western Australia has now been named the Red Setter Project, and the Company's Australian consultants, Terra Search Pty Ltd, have been commissioned to commence an exploration programme on the high priority magnetic targets recently identified by Terra Resources, as previously announced. Exploration efforts will focus on the Refer to Figure 1 for location map. Our initial plans are to compile a new detailed subsurface picture of the magnetic signature of the newly identified and untested 2,m long by m wide set of more info targets at depths starting at only m in depth, as identified by our independent consultants.

In parallel to this work, we also aim to The Career Exploration Research Project an MMI geochemistry survey for gold and base metals, which has been successfully used by other explorers and operators in the Patersons Ranges area where new gold discoveries have been found buried deep below surface. Wishbone reported on the 4 th November that their independent consultants at Terra Search Pty Ltd concluded:. In their report to Wishbone, Terra Search concluded that inversion of the broad spaced available Government magnetic data has produced potential targets with a similar signature to those at Havieron. A new close spaced high power detailed magnetics and gravity is recommended as the The Career Exploration Research Project phase of exploration, and this work could further delineate drill targets in this area.

A drilling programme could then be formulated to test the full range of geophysical targets on the licence. A magnetic inversion on the wide spaced government magnetics was also undertaken by Terra Resources and the data is attached Figure 2.

Results of this modelling shows several north plunging magnetic bodies of equivalent susceptibility possibly pyrrhotite alteration that is evident at both Newcrest Mining and Greatland Gold's Havieron and RioTinto's Winu discoveries. Previous shallow drilling failed to test the magnetic targets as shown in Figure 3. The 3D magnetic inversion Figure 2 looks at the required shape of magnetic bodies of a particular magnetic susceptibility to produce the The Career Exploration Research Project disturbance in the earth's magnetic field. The 3D magnetic inversion has used magnetic susceptibility values consistent with the Havieron deposit.

The series of plunging bodies could represent alteration systems associated with a hydrothermal system. The sections below Figure 3 across the magnetic anomaly show the position of the deeper drilling in relation to these bodies.

The drilling has not penetrated the main targets, but potentially show signs of hydrothermal activity with Calcite and albite alteration. Figure 2: 3D inversion on the magnetic anomaly showing potential targets. Figure 3. Sections through the magnetic inversion with drillholes project to section. The two previous RC drill holes that did penetrate the Permian cover intersected calcareous bedrock and a magnetite bearing mafic dyke.

Petrological work confirmed the presence of magnetite and sporadic base metal sulphides within the dolerite, and it was concluded that the weakly mineralised dolerite dyke is the source of the Stirling magnetic anomaly and the low levels of base metal anomalism in the surrounding sediments.

Terra Search, the author of this report has some direct experience with Havieron, having logged several thousand metres of core on the project in Wallrock clasts within the breccias at Havieron comprise fine grained, possibly hornfelsed, albite and calcite altered rock from an undetermined as at November protolith. Mineralisation at Havieron is spatially associated with a through-going dolerite that is generally barren so assumed to be late stagehowever there are numerous altered, early dolerite clasts and intrusives that are associated with locally spectacular gold grades.

The The Career Exploration Research Project magnetic anomaly at Havieron was interpreted to reflect the strong sulphide component, however modelling during indicated that this was not the case, and On Persuasive Child Abuse Essay the source was situated deeper than the drilling that was being undertaken at the time. Whole rock geochemistry could be used to determine the affinities of the dolerite, to determine if The Career Exploration Research Project is compositionally favourable as a source of introducing sulphide mineralisation. Separation of magnetite, and testwork to determine whether it is hydrothermal or igneous in origin would further add to the understanding of mineralisation potential. If it can be reliably captured, magnetic susceptibility values would provide valuable data to feed into the geophysical work proposed below.

Re-modelling of the magnetic anomaly, preferably with the collection of new close spaced detailed ground or airborne magnetic data and gravity, would be recommended. The depth to the top of the anomaly is constrained by drilling, and magnetic data from the existing chips would provide a useful start point. Due to the existing wide spaced m spacing for the current magnetic data, further targets may be identified with a closer spaced survey. It is also recommended that a new geochemical programme be undertaken using MMI and or Ionic leach over the entire tenement area. If the review of existing reports, completion of geophysical modelling and investigation of existing RC chips are favourable, drill testing will be the most successful exploration technique in this area.

RC testing of the magnetic feature is not yet complete. The magnetic anomaly has known strike extent that has not been The Career Exploration Research Project
