New analysis shows major resource potential at Cottesloe

Assessment and digitisation of Historical Drill Data shows

0.25% Copper (Cu), 4.6% Lead (Pb), 0.97% Zinc (Zn)

165 g/t Silver (Ag) and 0.26 % Cobalt (Co)

Paterson Range, Western Australia

Wishbone Gold Plc (AIM: WSBN, AQSE: WSBN), is pleased to announce reprocessed drill results from the Cottesloe project (including Cottesloe East announced in January) following the digitisation and combining of all previous data sets.

Size and Potential

The Cottesloe project has a well defined base metal anomaly of 2.5km with an anomalous rockchip and soil results extending the strike to 8km (Figure 1). Base metal anomalies with highest grades over 2 metre samples were 0.25% Copper (Cu), 4.6% Lead (Pb), 0.97% Zinc (Zn), 165 g/t Silver (Ag) and 0.26% Cobalt (Co). As previously reported Cottesloe and Cottesloe East have over 25 target areas within the combined project area.

The newly analysed data consists of 483 drill holes drilled By Esso, Amax and Occidental between 1976 and 1986. In addition there are multiple soil and rock chip analyses from City Resources, MIM (Mt Isa Mines) and BHP (1976-1996).

The best intercepts in this drilling were (Figure 2,3):

*Drill Intercepts previously reported.

The main base metal zone in the closer spaced drilling is already 2.5km long and is open to the north, with continuities indicated in rock chips, soils and drilling throughout the basin along the target horizon of over 8km strike length (Figure 1).

Architecture and anomalism is highly prospective for sediment hosted base metal mineralisation similar to that at nearby Nifty (Cu) and Maroochydore (Cu-Co) and also the Mt Isa style (Zn-Pb-Ag) deposits.

Richard Poulden, Wishbone Gold's Chairman, commented;

"Terra Search finding and analysing this historic drill and exploration data provides a major step forward in our knowledge of the Cottesloe group. Using this data we are effectively building off three historic drilling programs providing several years of data. Coupled with our new experience of the MT technology we are pleased to be this far ahead before starting our own drill campaign. With silver, cobalt, lead and zinc grades this high in the targeted area this is hugely promising."

Mobile Magneto Tellurics (MT)

As previously announced with Red Setter, Mobile MT has been flown over the entire Cottesloe tenements. As with Red Setter, the data will be interpreted by Southern Geoscience Consultants ("SGC"). SGC will incorporate the newly digitalized data and results from the MT program into the existing model. Once target areas are defined further Heritage approvals will be conducted if necessary to cover the future drill program.

The anomalous zones at the Cottesloe prospect mark out three separate anomalies as shown in Figures 2 and 3. These consist of 2 stratabound anomalies within the hinge of the syncline which are clearly defined by strong Pb, Ag anomalies with support from Zn, Cu and Co. A third anomaly in the centre of the hinge zone is defined by a very strong Zn anomaly with support in Co.

This is interpreted to be a potential leakage anomaly from the deeper base metal horizon. During weathering, metal mobility varies depending on the metal with Pb and Ag being the least mobile, then Cu, with Zn and Co the most mobile. This explains the patterns of anomalism within the prospect (Figure 3).

Cottesloe East

Highlights:

-- Review of historical work shows strong copper anomalism along the contact between the base of the Broadhurst Formation and the Coolbro Sandstone

-- Strong potential for Sediment hosted mineralisation similar to that at Nifty 50km to the north.

-- Copper anomalism within the tenement of up to 3880 ppm Cu (0.39% Cu) in soils, 2150ppm Cu in drilling, 1440ppm Cu in Lag and 1703ppm Cu in Rockchips.

Historical work summary

The tenement covers the eastern portion of a basin of the Broadhurst Formation within a major syncline above the Coolbro Sandstone. This stratigraphy is the same as that at the Nifty Copper project.

A detailed review of the historic work has been undertaken showing a strong, consistent pattern of copper anomalism along the base of the Broadhurst Formation within drilling, rockchip, soil and lag sampling. The anomalous results occur over a 15km strike , (Figure 4) that remains largely untested by systematic work.

Work carried out comprised sporadic stream sediment samples, soil & lag focused on the south-eastern portion of the tenement and a small number of diamond and percussion drilling focussed on the lithological contact of the Coolbro sandstone and the Broadhurst Shale-sandstone. This contact is conformable in some cases but may be a faulted contact in this vicinity. Soil samples retuned up to 3880 ppm Cu along this contact zone within the tenement and Rock chips up to 1703 ppm Cu.

Drillholes within the tenement were primarily targeting Uranium anomalism rather than base metal. There were two holes that tested the contact zone both of which hit anomalous base metals with BR5 intersecting up to 2150ppm Cu at 100m depth & BR7 560ppm Cu @ 120m depth. The fold closure just south of the tenement shows strong anomalism both at surface and in drill hole SR7 which intersected 15m @ 1940 ppm Cu from 32m with a peak value of 3350ppm Cu.

The only more focused soil- lag sampling was carried out over the Broadhurst Formation by BHP in the south-eastern area of the tenement. It highlights a Cu anomaly over a 3km zone with results of up to 766 & 1440ppm in lag sampling.
