OVERVIEW OF EXPLORATION PROJECTS
WESTERN AUSTRALIA
GIDGEE PROJECT
During the period the company has continued its review of all project data, with some significant results being outlined as announced to the market subsequent to the end of the quarter on July 16 2009. This review has recognised the significance of previous drilling data, including intersections of 23m @ 0.67 g/t Au and 102m @ 0.42 g/t Au in drillhole WRC012.
The company has received the draft report for the resource estimations at Whistler, Rosie and Central/Bullseye, and is currently reviewing the results of this work.
The company carried out a 47 hole, 3368m aircore drilling programme at The Cup, Julia’s Fault and Montague North, with highly anomalous gold being intersected at Julia’s Fault, and reinforcing the prospectivity of this area. Interpretations of The Cup and Julia’s Fault areas are under way.

Gateway 85%, Herald Resources 15%
The company has largely completed a review of the historic exploration data, with this review confirming that there is significant potential for the discovery of additional sulphide gold mineralisation within the area, given only limited drilling has been carried out below the oxide zone. This work has also delineated previously drilled areas that are worthy of follow up to define additional oxide mineralisation.
As reported to the market on July 16 2009, subsequent to the end of the quarter, the data review concluded that broad low grade intersections, including 23m @ 0.67 g/t Au and 102m @ 0.42g/t Au in hole WRC012 at Rosie North are significant, with these yet to be followed up. The intersections remain open in all directions, and one interpretation is that they could represent a halo to a gold mineralised system to the east of Rosie North. Hole locations are shown in figure 4, with hole and intersection details previously reported to the market. The review has also outlined potential target zones at Whistler as presented in the July 16 release.
Interpretations and target areas at Whistler were also released to the market in the July 16, 2009 release.
Preliminary resource calculations for Whistler, the Rosie area and Central/Bullseye areas have now been completed, and the company is reviewing the consultant’s draft report.
Following the results of the previous sub-audio magnetics (SAM) survey to the east of Whistler, the company plans to carry out a further survey over, and to the east of the Airport gold trend. This, along with the results of the data review will be used to plan future drilling programmes.
The Cup E57/417
Gateway 100%
One aircore drillhole was completed at The Cup; however this failed to reach the target depth due to drilling conditions.
The Cup South E57/417 and E57/561
Gateway 100% / Gateway 75%/Red 5 25%
Seven aircore holes for 610m were completed to test a mid-channel response EM conductor approximately 2km south of The Cup prospect. A narrow zone of semimassive pyrite was intersected, which may explain the anomaly. The only geochemical response was weak arsenic anomalism associated with a shallowly west dipping folded gossanous horizon.
Julia’s Fault M57/429
Gateway 75%/Red 5 25%
Twenty five aircore holes totalling 1703m were drilled in the Julia’s Fault area.
Seven holes drilled to the south near the M57/429 and E57561 boundary (GAC26 to 32) returned variably anomalous Au, As and Cu, in gossanous material, that may

reflect a weathered sulphidic black shale horizon, similar to that seen at Julia’s Fault proper. Hole GAC031 intersected 2m @ 0.55g/t Au at the end of the hole, and therefore requires further follow up.
Drilling at Julia’s Fault intersected the same gossanous horizon as intersected in past driling, interpreted to be a folded and weathered sulphidic black shale. This horizon is associated with highly anomalous gold intersections as shown below, with in a number of cases the aircore holes terminating in anomalous gold due to the inability to drill through the gossans. Previous drilling also encountered similar difficulties.

Recent interpretations suggest that gold mineralisation at Julia’s Fault may be controlled by the intersection of NNW structures and a reactive sulphidic black shale horizon, and an interpretation is near completion.
Results of this interpretation to date indicate areas that have not been fully drill tested, and also reinforce the need to drill deeper in places where holes drilled to date have terminated (due to drilling difficulties) in mineralisation. Results of previous drilling programmes have been presented in past company releases to the market.
A map of the interpreted gossanous horizon and conceptual cross section is presented as figure 5, and final results of the interpretation will be released to the market when completed.
Bungarra West Joint Venture E57/709 / North Montague Area P57/1179, P57/1181
Gateway 30%, Legend Mining 70%/ Gateway 100%
Three short RAB holes totalling 45m were drilled across a strong EM conductor located within P57/1181, 100% held by Gateway. The anomaly is spatially associated with ironstone outcrops of possible sulphide origin. Lack of penetration of the drilling resulted in the target not being adequately tested
The ground EM anomaly identified in the southern part of the JV tenement (E47/709) has been modelled by Legend Mining, defining three moderate to strong conductors. The conductors have depths ranging from 30m to 100m and strike E-W and WNWESE with vertical to steep northerly dips.
Ground reconnaissance over the EM conductors was undertaken. Three rockchip samples of ferruginous/gossan material returned a maximum gold value of 377 ppb Au.

The significance of the EM anomalies is not clear, and drill testing of these features is planned by Legend.

A weak EM anomaly coincident with the base of a magnetic ultramafic unit was investigated as a potential Kambalda style nickel target.
Field investigations concluded the anomaly to be associated with an outcropping weakly suphidic chert that is interpreted as being at the base of an ultramafic unit.
Rock chip and soil sampling returned no geochemistry indicative of nickel mineralisation. The chert however returned weak gold anomalism of 92ppb. The anomalism may warrant limited follow up as a low order gold target.
NEW SOUTH WALES
COWRA PROJECT EL 5514 & 6102
Gateway Mining 100%; Minotaur and Mitsubishi Corporation - Mitsubishi Materials Corporation earning 51% and 24% respectively.
Ground geophysical surveys were undertaken as follow-up work to the airborne electromagnetic (VTEM) surveys completed in the previous quarter. A total of 16.8 line kilometres of ground electromagnetic surveys and 35 line kilometres of ground magnetic surveys were completed over 9 VTEM targets. Eight of the targets gave excellent ground geophysical responses and are undergoing 3D modelling to assist drill planning, which is expected to commence during the next quarter.
Minotaur has now formally advised the company that they have met the $700,000 expenditure commitment and that they have earned 51%. They advise that they will sole fund and work towards the second expenditure requirement. To date $958,000 has been spent by the current JV partners on the Cowra Project.
