VENUS ENTERS NEW EXPLORATION JOINT VENTURE ADJACENT TO ARGYLE DIAMOND MINE

Venus Resources Limited ("Venus Resources" or "Company") is pleased to announce a new joint venture in its search for a diamond bearing pipes north of the Argyle Diamond Mine, under younger cover rocks.

The Company has entered into a joint venture agreement with Seaward Holdings Pty Ltd (a company controlled by Mr Matthew Hogan, a director of Venus Resources) ("Seaward") over tenement E80/3359 ("Tenement") which is located adjacent to the Argyle Mining Lease and also adjacent to E80/3253 owned 95% by Venus Resources.

Under the terms of the joint venture, Venus Resources may earn a 70% equity in the Tenement by completing a bankable feasibility study on any diamond deposit found. Until completion of the bankable feasibility study, Venus Resources will have no interest in the Tenement. There is no minimum expenditure commitment (except to keep the Tenement in good standing) and Venus Resources may withdraw from the joint venture at any time. The key terms of the joint venture agreement are set out on page 4 of this release.

Information on the Tenement and Report highlights

E80/3359 is located 20 kilometres from the Argyle Diamond Mine and covers an area of approximately 21 square kilometres. A large proportion of the Tenement is covered by Cambrian aged basalt (600 million years old) which Venus Resources considers has the potential to hide an undiscovered lamproite pipe.

Work on the Tenement over the last 15 years has been non-existent due to Aboriginal land right issues. The solid relationship established between Venus Resources and the traditional family groups has now facilitated access and exploration to the ground the subject of the Tenement .

The independent Directors of the Company commissioned an Independent Consulting Geologists Report ("Report") on the Tenement, a complete copy of which is appended to this release.

Highlights from the Report are as follows:

The main target in E80/3359 is a low-lying valley consisting of Cambrian basalt with high ridges to the south and west. The ridges consist of older Lissadell Formation quartzite. A creek flows southeastward through the valley and cuts a steep gorge in the quartzite ridge to the south of the target. The south ridge is controlled by a major fault which trends northeast through the tenement and intersects with the Glenhill fault zone beyond the licence area in this direction. The fault is considered to be important as it represents a major splay on the Glenhill Fault. The gorge to the south of the target area is thought to be controlled by a local north-south trending fault or lineament.

This relatively minor structure is significant as it represents a cross-trend which may produce a dilational zone on the north side of the intersection with the main northeast trending fault. This conceptual dilation zone, now buried by younger basalt, represents the main target in E80/3359.

Significantly, the geometry of the faults at Target 1 is similar to the geometry of the Razor Ridge and Gap Faults at Argyle. That is, a secondary fault trending approximately east-west intersects with the primary fault trending north-south.

Furthermore, the dimensions of the valley are roughly the same size as the Argyle pipe before it was tilted down-to-the-north in the Devonian.

Based on the present data, it is difficult to estimate the thickness of the Cambrian basaltic rocks which fills the valley. If the relatively shallow dipping edges of the Proterozoic outcrops are followed down-dip, the Cambrian basalt may be somewhere between 50-250 metres in depth.

The writer is of the opinion that Target 1 satisfies the geological requirements on which the exploration concepts at Argyle North are based:

• It lies within the Glenhill Fault Corridor, • the fault pattern at the target is similar to Argyle, • the cover rocks may be relatively thin and • the valley could accommodate a substantial intrusion.

The report goes on to conclude that

“Venus Resources has the potential via the completion of a bankable feasibility study to earn a 70% interest in E80/3359. This is a high risk high reward exploration play based on sound geological concepts.

2 The opportunity to acquire additional ground in the highly prospective structural corridor to the north of the Argyle Diamond Mine where diamond bearing lamproite pipes may have been intruded but be buried below younger cover rocks and therefore hidden from discovery is considered consistent with the stated objectives of Venus Resources and previous tenement acquisitions and work programs completed by them. Success in high risk exploration requires the ability to relatively cheaply test a range of targets and quite often the more targets tested the greater chance of success.

Targets have been defined within E80/3359 where this cover sequence may be relatively thin and/or where the fault patterns suggest that intrusions are more likely to have occurred. These targets require drill testing to test for the presence of buried lamproite pipes. ”

Planned work programme

A work programme designed to systematically drill test the target areas has been planned with site clearances complete and drilling is due to commence in the seconjd week of September.

INDEPENDENT CONSULTING GEOLOGIST’S REPORT

E 80/3359

1st August 2008 The Independent Directors Venus Resources Mezzanine Level BGC Building 28 The Esplanade Perth WA, 6000

Dear Sirs,

At the request of Venus Resources (Venus), R. Russell and Associates (RR&A) has prepared this independent geological report on the diamond exploration project within E80/3359, located approximately 20 kilometres from the Argyle Diamond Mine. The project is located in ’s East Kimberley area and is currently held by Seaward Holdings Pty Ltd (a company controlled by Mr Matthew Hogan, a director of Venus Resources Limited and therefore a related party of Venus Resources Limited).

The report has been prepared in accordance with the Code and Guidelines for Assessment and Valuation of Mineral Assets and Mineral Securities for Independent Expert Reports (the Valmin Code) which is binding upon Members of the Australasian Institute of Mining and Metallurgy (“AusIMM”). It has been prepared by J. Richard Russell, principal of R. Russell and Associates (RR&A) who is a Member of the AusIMM and a qualified geologist with 25 years experience in mineral exploration.

Neither the writer, nor any of his associates or employees have any interest either direct, indirect or contingent neither in Venus nor in any of the mineral assets included in this report nor in any other Venus asset nor has any such interest existed previously.

Site visits have been made to the project areas within E80/3559. Information used in the preparation of this report has been derived from site visits, technical information provided by Venus and other publicly available data.

For the purpose of Sections 731 to 733 of the Corporations Act, RR&A were involved in the preparation of the Independent Consulting Geologists Report of Mineral Exploration Properties included in the original Venus Resources Limited Prospectus (dated 23rd April 2007).

A detailed geological report follows however in summary:

We are of the opinion that:

5 a) The targets within E80/3359 are conceptually sound and relate to the intersection of major fault structures with the potential to provide conduits of potentially diamond bearing lamproite pipes emplaced at a similar time to the Argyle pipe dated at approximately 1.2 billion years old. b) These targets are located underneath Cambrian aged (600 my) basaltic rocks which would have hidden any pipes present from discovery. c) Venus has a satisfactorily and clearly defined exploration and expenditure programme focused on testing the targets via reverse circulation drilling. Drilling is the most effective method to explore for undiscovered diamond bearing lamproite pipes under the younger cover rocks. d) Sufficient preliminary work has taken place to justify the budgeted exploration and expenditure programme. e) The proposed minimum expenditure commitment is entirely consistent with the current geological knowledge of the project. f) It is beyond the scope of this report to comment specifically on the proposed commercial transaction between Venus and Seaward, however we note the following:

1) Valid diamond pipe targets located in the vicinity of the Argyle Diamond Mine and hidden under younger cover rocks are rare and offer the potential for new and significant discoveries. 2) Venus may withdraw at any stage with no payments or benefits to Seaward, except to maintain the tenement in good standing and we note the minimum expenditure commitment is only $20,000/annum. 3) There is no cash or shares to be issued to Seaward under the terms of the JV except for the repayment of past expenses estimated at $6,000. 4) All future expenditure is solely dependent on the results 5) Venus has the right to earn a 70% interest in the tenement following the completion of a bankable feasibility study. 6) It is our belief that given the potential exploration prize the proposed deal provides Venus with the opportunity to test a valid diamond exploration target and potentially earn a 70% interest in any diamond pipe discovery in close proximity to the Argyle Diamond mine in a prospective structural setting.

7 1 ARGYLE NORTH PROJECT

1.1 Introduction

Venus Resources Limited proposes to enter into a Farmin and Joint Venture with Seaward Holdings Pty Ltd over tenement E80/3359, located in the East Kimberley region of Western Australia (Figure 1). The project is located 18 kilometres north of the Argyle Diamond Mine and contains targets of diamond bearing lamproite intrusions that my be buried below younger cover rocks on similar fault systems to those which are thought to control the Argyle pipe.

2.2 Tenure, Location and Access

The tenement E80/3359 is 20.8 square kilometres in extent and was granted for a five year period on the 19th March 2008. The project area is in the central part of the Lissadell 1:250,000 sheet area and on the Dunham River 1:100,000 sheet.

The project is located on the Glenhill Station with a number of station tracks transecting the tenement and providing relatively easy access to the areas of interest. The nearest supply centre is the major town of Kununurra which is located about 80 kilometres north- northeast of the project area but about 140 kilometres by road.

2.3 Exploration History

There is little open file data available in the project area. Much of the early exploration appears to have been carried out as ‘open-range’ reconnaissance exploration without tenements. This approach precluded the requirements for formal reporting so the results are not available for assessment. However, the writer believes that, following the discovery of the Argyle Pipe in 1979, the main creeks in the project area were sampled for kimberlitic heavy minerals by the CRA/Ashton Joint Venture.

Basaltic volcanics were found to be outcropping extensively throughout the entire tenement area except on the margins of the tenement, where the older Proterozoic rocks are present.

Apart from the open-range stream sediment sampling, the project area itself remains largely unexplored. It must be pointed out that stream sediment sampling is extremely unlikely to locate a diamond bearing pipe which is buried below cover rocks.

An independent report commissioned by a previous tenement holder in May 2001, “Potential for Lamproite Pipe and NeoProterozoic Paleo-alluvial Diamond Deposits beneath the Early Cambrian Antrim Plateau Volcanics within the Ragged Range Paleo- Valley, Halls Creek Mobile Belt” has been obtained and reviewed.

This report suggests that “Although diamond provinces typically contain clusters of /, historical exploration around the Argyle pipe has only resulted in the discovery of a few, very small, deeply eroded dykes. It is feasible that the 1200-1100

8 MA diamond-bearing lamproite pipes, other than the Argyle pipe, utilised the Glen Hill Fault system (and its associated secondary splays) to intrude the Carr Boyd Group. These pipes might have a similar geological history but are yet to be exposed by erosion from beneath the basalt cover and therefore remain to be discovered. These pipes are likely to be will preserved like the Argyle pipe.”

The report goes on to say “the Glen Hill Fault system is also the major geological entity that guided the development of the Ragged Range palaeo-valley. Repeated movement along the fault has resulted in a complex history of sediment/volcanic deposition and erosion within the palaeo-valley. The Glen Hill Fault was not only instrumental in providing a transport route and home for the Argyle pipe but also effectively sheltered it from erosion through the development of the Ragged Range palaeo-valley. “

“The ideal dilational structural site (i.e, fault dilation) that hosts the Argyle pipe could be repeated at numerous sites along the Glen Hill Fault system further to the north beneath the Neoproterozoic and Paleozoic formations within the Ragged Range palaeo-valley. These buried dilational sites could host diamond-bearing lamproites that are even better preserved than the Argyle pipe as they would remain untouched by Tertiary erosion. Dilational sites are likely to be developed at fault intersections, bends or terminations along either the main Glen Hill Fault or its second order splays.”

No on-ground exploration was completed by the previous tenement holder whose work was limited to literature studies and conceptual targeting.

2.4 Geological Setting in the Halls Creek Orogen

2.4.1 Structure

The project is located in the Halls Creek Orogen in the East Kimberley region of Western Australia (Figure 1). The orogen is a northeasterley trending belt formed in the Palaeoproterozoic when the Kimberley Craton to the northwest collided with a composite Archaean craton to the southeast. The orogen represents a major mobile zone that continued to be structurally active into the Phanerozoic. The final major structural event occurred during the Devonian when many of the major strike slip faults were reactivated and coarse clastic sediments filled fault-controlled troughs (Veevers, 1969; Dow and Gemuts, 1969).

2.4.4 Cambrian and Devonian cover rocks

The Cambrian Antrim Plateau Volcanics unconformably overlie the Proterozoic rocks (Figure 4). These flood basalts buried a landscape of considerable relief in this part of the East Kimberley. A major valley was probably located to the west of the Glenhill Fault which may have been a fjord or partly frozen flooded glacial valley. The outpourings initially filling the valleys and, with successive outpourings, covered the crests of the ranges (Traves, 1955).

9 The volcanics are unconformably overlain in the project area by coarse-grained sediments of the Devonian Ragged Range and Galloping Creek formations. These deposits were laid down in the Early Upper Devonian (about 380 million years ago (Ma)) following major movements along the Glenhill and Revolver Creek Faults. The faulting produced uplift to the west and in the Carr Boyd Ranges to the east of the project (Mory and Beere, 1988). To the east of the Glenhill Fault, the Devonian sediments are dominated by coarse sandstones with pebble layers and these are thought by the writer to represent braidplain and river outwash deposits.

2.4.5 The origin of diamonds

Diamond geologists generally agree that diamonds were formed in a so-called ‘diamond stability field’ in the upper mantle lithosphere. This zone occurs at depths of over 150 kilometres where the pressure is high (over 40 kilobars) and the temperature is moderate (between about 1,000OC to 1,200OC). This upper mantle environment is regarded as relatively ‘cool’ and occurs below older parts of the earth’s crust known as cratons. These cratons are usually older than the Palaeoproterozoic era (about 1,600 Ma) and often date from the Archaean era which ended about 2,500 Ma.

12 Diamonds crystallised in an ultrabasic peridotic magma in which mantle rocks, which are relatively rare at the surface, are common. The main mineral constituents of these peridotitic rocks are olivine, pyrope , orthopyroxene, clinopyroxene, chromite and ilmenite which occur in various proportions. The diamonds are usually only a minor component of the magma.

Under the right tectonic conditions, a fluidised mixture consisting of liquid and gas-rich magmas mixed with fragments of mantle rocks, possibly including diamonds, made its way along faults or other weaknesses in the overlying crust (‘conduits’) to the surface. The magma would have intruded rapidly into the crustal surface rocks where it solidified in or lamproite dykes, sills or pipes. The intrusion of kimberlite and lamproite magmas is usually accompanied by powerful explosions as the hot, highly-pressured gas- charged magma passes through the groundwater near the surface. This type of explosive intrusion is known as a ‘diatreme’. Diatremes often comprise feeder dykes at lower levels and volcanic breccia and crater-fill deposits at higher levels. The size and shape of the diatremes may vary but a diameter of more than 1,000 metres is unusual. It is common for the upper parts of the diatreme to be eroded and the actual crater of the pipe is usually absent. Both kimberlite and lamproite pipes occur in clusters or fields. A typical cluster may contain 10 to 20 pipes although clusters of over 50 pipes are known. The diamond content of the pipes in the same cluster is often highly variable.

The kimberlite or lamproite itself consists of various rock fragments derived either from the mantle or torn off the walls of the intrusion during the passage of the magma. These rocks are commonly rounded by the intense abrasion produced within the upward moving magma. Near the surface, local rocks may have slumped into the magma from above after the eruption formed a crater at the surface. The kimberlite or lamproite is therefore said to be a hybrid breccia, or rock composed of different types of fragments which have been welded together by the hardened magma.

Lamproite or kimberlitic eruptions are not generally accompanied by large volumes of lava or extrusive rocks. Once the magma has been emplaced, it is easily weathered and rapidly eroded by natural processes. The more resistant mantle minerals in the pipe (such as , ilmenite or chromite) together with any diamonds which may be present, are liberated into the local soils and then into the rivers draining the area around the pipe. These minerals become the pathfinder minerals used for locating kimberlite and lamproite diatremes and are known as ‘kimberlitic indicator minerals’. They are recovered from stream sediment samples or loam samples. Diamonds are so rare, even in concentrations of indicator minerals, that they are often only recovered from samples taken in relatively close proximity to the source pipe. The erosional history of the pipe is important in determining the dispersion pattern of the diamonds and indicator minerals.

If the pipe is covered by a sequence of younger volcanic rocks, there will be no further introduction of kimberlitic material into the soils and creeks. This usually means that there will be little or no evidence of the whereabouts of the pipe.

13 2.4.6 The Argyle diamond pipe

Three groups of ultrabasic intrusions are present in the East Kimberley region (Jaques et al, 1986). By far the most economically important and significant for the present project are the diamondiferous olivine lamproite intrusions at Argyle and a few kilometres to the southwest at the Lissadell Road Dykes. The Argyle pipe has been dated at 1177 +- 47 Ma and is 50 hectares in size (Boxer, et al, 1986). Apart from the Lissadell Road Dykes, which have been interpreted as the possible root zone of a second lamproite pipe, no further pipes have been found. This is unusual as deep-seated intrusions of the Argyle type usually occur as part of a cluster of intrusions.

The local conduit for the pipe appears to have been the southern part of the north-south trending Glenhill Fault, known locally as the ‘Gap Fault’. The actual point of intrusion was at the intersection between the east-northeast trending ‘Razor Ridge Fault’ and the Gap Fault. These controls appear to have been important in the upper, brittle part of the crust. At deeper levels, the major Halls Creek Fault, which trends north-northeast about 7km to the east of the pipe, may be the mantle-tapping conduit along which the lamproite magma was initially channelled toward the surface.

2.5 Exploration Concepts

2.5.1 Glenhill Fault Corridor

The Glenhill Fault has been identified as the main control on the emplacement of the Argyle lamproite. This fault continues for at least 50 kilometres to the north of Argyle and is therefore viewed as a prospective structural corridor for further diamond bearing intrusions.

Exploration to the north of the Argyle lamproite has mainly involved mapping and stream sediment sampling by CRA and Ashton Mining, the Argyle Joint Venture and other companies. To date, no further lamproite intrusions have been discovered.

2.5.2 Cover rocks

Much of the area to the north of Argyle is covered by Cambrian volcanics and Devonian sediments (Figure 5). These rocks are half the age or less than the Argyle lamproite. While it is widely acknowledged that further diatremes of the same type and age as Argyle could occur to the north, previous explorers have been deterred by the assumption that the cover is prohibitively thick and that the area is structurally complex.

2.5.3 Exploration Model

While acknowledging that the geological issues of locating a buried diatreme to the north of Argyle may be challenging, exploration may not be prohibitively difficult. In the writer’s opinion, two considerations may have been overlooked or not fully appreciated by previous explorers:

14 1. A considerable amount of erosion has occurred in the period following the deposition of the cover rocks. There is the possibility that some of the buried pipes may now lie below much thinner cover accessible to modern exploration and mining techniques.

2. The area to the north of Argyle is indeed structurally complex. However, much of the structuring may not be important in the context of locating further buried diatremes. Structurally, targets can be localised to:

• The prospective corridor along the Glenhill Fault Zone • The intersection zones between secondary cross faults and the main fault zone. In particular, intersection zones similar to the geometry of the Gap and Razor Ridge fault intersection, which controls the Argyle intrusion, would be particularly prospective.

Within this structural context, a major target area is identified in E80/3359 where diatremes buried below Cambrian aged basalts may occur. The target is located on the intersection of an interpreted major NE trending structure (clearly visible on the magnetic image) with a north trending structure providing possible dilationary positions at the time of emplacement of the Argyle diamond pipe.

3 TARGETS

Photo geological mapping (Russell, 2006) has located structurally and geomorphologically significant features which may represent diatremes buried under Cambrian basaltic cover rocks within E80/3359.

3.1 Target 1

The main target in E80/3359 is a low-lying valley consisting of Cambrian basalt with high ridges to the south and west. The ridges consist of older Lissadell Formation quartzite. A creek flows southeastward through the valley and cuts a steep gorge in the quartzite ridge to the south of the target. The south ridge is controlled by a major fault which trends northeast through the tenement and intersects with the Glenhill fault zone beyond the licence area in this direction. The fault is considered to be important as it represents a major splay on the Glenhill Fault. The gorge to the south of the target area is thought to be controlled by a local north-south trending fault or lineament.

This relatively minor structure is significant as it represents a cross-trend which may produce a dilational zone on the north side of the intersection with the main northeast trending fault. This conceptual dilation zone, now buried by younger basalt, represents the main target in E80/3359.

Significantly, the geometry of the faults at Target 1 is similar to the geometry of the Razor Ridge and Gap Faults at Argyle. That is, a secondary fault trending approximately east-west intersects with the primary fault trending north-south. Furthermore, the dimensions of the valley are roughly the same size as the Argyle pipe before it was tilted down-to-the-north in the Devonian.

15

Based on the present data, it is difficult to estimate the thickness of the Cambrian basaltic rocks which fills the valley. If the relatively shallow dipping edges of the Proterozoic outcrops are followed down-dip, the Cambrian basalt may be somewhere between 50-250 metres in depth.

From the previously completed program by Venus on its adjacent tenement E80/3253, cover sequences of up to 200 metres thick were successfully drill tested and no major impediment to the testing of the targets is foreseen.

The writer is of the opinion that Target 1 satisfies the geological requirements on which the exploration concepts at Argyle North are based:

• It lies within the Glenhill Fault Corridor, • the fault pattern at the target is similar to Argyle, • the cover rocks may be relatively thin and • the valley could accommodate a substantial intrusion.

4 CONCLUSIONS AND RECOMMENDATIONS

Venus Resources has the potential via the completion of a bankable feasibility study to earn a 70% interest in E80/3359. This is a high risk high reward exploration play based on sound geological concepts.

The opportunity to acquire additional ground in the highly prospective structural corridor to the north of the Argyle Diamond Mine where diamond bearing lamproite pipes may have been intruded but be buried below younger cover rocks and therefore hidden from discovery is considered consistent with the stated objectives of Venus Resources and previous tenement acquisitions and work programs completed by them.

Success in high risk exploration requires the ability to relatively cheaply test a range of targets and quite often the more targets tested the greater chance of success.

Targets have been defined within E80/3359 where this cover sequence may be relatively thin and/or where the fault patterns suggest that intrusions are more likely to have occurred. These targets require drill testing to test for the presence of buried lamproite pipes.
