VMS Prospects

==> picture [234 x 84] intentionally omitted <==

Summary

Gidgee project hosted in greenstone terrain of the Yilgarn Craton
Highly prospective VMS targets – targeting high grade Cu/Zn deposits
Significant untested Electromagnetic (EM) anomalies extending the entire project length – over 30km of potential strike length
Shallow aircore/RAB drilling has historically returned typical VMS geochemical element suite: Cu, Zn, Pb, Au, Ag, As, Bi, Cd, Co, In, Sb, Mo, Sn, Se, Te coincident with EM anomalies  highly suggestive of base metal fertility
Discovery of ‘The Cup’ prospect in 2006 changed focus of Gateway from Gold to VMS
VMS Deposits occur in clusters; strong likelihood of other VMS mineralisation nearby
RC results at ‘The Cup’ include:
76m @ 0.7% Cu including 20m @ 1.57%

Minimal follow up drilling

44m @ 0.8% Cu including 9m @ 2.0%
Only 9 RC holes drilled at ‘The Cup’; 300m known strike length but appears to be part of a much larger system & open to the north, south & east
Potentially fertile VMS systems widely identified, with over 30km of prospective strike extent inside the current project area

Right Geological Environment for VMS deposits

Typical VMS terrain - Mafic Volcanics and Felsic/Intermediate Volcanic/Volcaniclastic Sequence (Achaean - Primitive Type) typical of ‘Bi-Modal Mafic’ packages which host a number of VMS deposits in the Yilgarn
30 km of prospective strike extent inside the project area
The ‘Montague Granodiorite’ intrusion is the probable source of felsic volcanic activity and the “ heat engine” which drove the VMS mineralisation – chemical composition of the granite is typical of sub-volcanic intrusions associated with this style of VMS
Numerous outcropping gossans , indicative of massive sulphide accumulations
Shallow transported cover (approx. 10m) overlies a significant proportion of prospective strike in the southwest of the project area at Gossans Galore and Gravel Pit, representing a significant exploration frontier

Project Overview - VMS

All the hallmarks of a Fertile VMS System

Alteration (sericite and chlorite) indicative of VMS systems identified widely across the project area in litho-geochemical test work

----- Start of picture text -----

The Cup - Significant Cu Discovery
----- End of picture text -----

MLTEM and VTEM anomalies geophysical surveys have located numerous conductive anomalies – VMS deposits are typically characterised by EM anomalism
Geochemical sampling of surface and subsurface gossan has identified wide spread anomalism for Cu, Zn, Ag, Au, Bi, Co, Mo, Sn, As, Sb, Se & Te typical of VMS Archaean Primitive Type mineralisation
Many areas with strong geochemistry have coincident EM conductors, suggesting base metal fertility below historical shallow drilling
RC, Aircore and RAB drilling have intersected significant Cu and Zn anomalism across the project’s entire prospective strike extent
Early exploration endeavour has intersected significant copper mineralisation at The Cup
Minimal exploration to the south of The Cup (Gravel Pit - approx 12km of prospective strike) has shallow anomalism of similar magnitude to that at The Cup – believed to be part of the same structure

Bevan and Bigfinger

•Historic surface rock chip sampling is highly anomalous for copper and zinc, up to 5.7% Cu

•Historic angled RAB drilling intersected copper and zinc mineralisation from surface – anomalous zones in orange, >0.2% Cu

•VTEM conductivity increases to the south along strike of strongly mineralised drilling at Bevan; yet to be tested; planned testing for RC program in July

•Next drill testing of southern mineralised extent at Bevan is 100m along strike and consists of shallow angled RAB drilling only, maximum of 35m down hole depth- does not test conductive zone below

Birthday Gossan

Coincident gossan outcrop and sub-crop in strongly weathered terrain - minor exploration to date
Rock chip sampling Anomalous for copper and zinc Highly anomalous pathfinder element
concentrations for Bi, Mo, Sn, Se and Ag.

As and Sb are also anomalous. Pathfinder elements are relatively immobile during weathering and potentially indicate target metal concentration below the highly weathered, metal depletion zone

Rock chip sample: Cu - 0.09% Zn - 0.004% Ag – 5.14g/t Bi - 8.08ppm Mo – 6.28ppm Sn – 9.4ppm Se – 32ppm

One hole drilled - GRC225 (did not test sulphide zone)

Intersected highly weathered gossanous material from 15–35m. Anomalous base metals and promising pathfinder element concentrations.

Target Metals in depleted zone (max dh grades) Cu - 0.076%, Zn - 0.13%

Pathfinder Elements (max dh grades)

Bi - 7.11ppm (aprx. 4 times greater than at The Cup mineralisation) Mo – 6.91ppm (aprx. same level as at The Cup mineralisation) Sn – 10.9ppm (aprx. 2 times greater than at The Cup mineralisation) Ag – 0.48g/t (aprx. 1/3[rd] level at The Cup mineralisation)

Other Gidgee Prospects

Victory Creek ( 75% Gateway; 25% Estuary Resources Ltd)

==> picture [385 x 307] intentionally omitted <==

Subject to JV with Placer Dome in 2006 prior to takeover by Barrick Gold
Placer “targeting minimum 5.0 million oz gold resource”[1]
Placer interpreted Victory Creek as having similarities to the Wallaby Deposit (7.1m ozs Au)
Very strong multi-element anomalism & broad zones of gold mineralisation (0.4 – 0.5 g/t Au) near surface
JV terminated early upon Placer takeover by Barrick Gold
Yet to be properly tested
Potential remains for Victory Creek to host an exceptionally large gold resource
