Scoping Study for Moolart Well Gold Project Commences
Key Points
- Commencement of a Scoping Study on the Moolart Well gold project in the Duketon $\bullet$ joint venture, north Laverton area, WA.
- Moolart Well has the potential to host at least 1 million ounces of gold down to a vertical depth of 100m, with 458,000oz already in a shallow laterite resource down to an average depth of 8m.
- The scoping study will evaluate the technical parameters and the broad economic $\bullet$ options for development of a gold mining operation based on the Moolart Well project;
- A 25,000m drilling program at Moolart Well has commenced in conjunction with the $\bullet$ Scoping Study:
- The cost of the Scoping Study and associated drilling will be approximately \$1.4 $\bullet$ million (100% basis) and Regis' share will be met from existing cash reserves:
- The results of the Scoping Study are expected to be reported to the market early in the December quarter.
Summary of Announcement
On 26 May 2005 Regis Resources NL ("Regis"; ASX code RRL) announced that it had elected to move to management of the Rosemont Duketon and the Duketon Region joint ventures ("Duketon joint venture") in the north Laverton region of Western Australia. The Directors of Regis are now pleased to further announce the commencement of a Scoping Study over the Moolart Well gold project within the Duketon joint venture area. The Moolart Well property currently contains a resource of 458,000 oz of gold in laterite over a 4km strike length down to an average depth of 8m. Only broad spaced exploration has been undertaken on the mineralisation known to exist beneath the laterite zone. The Scoping Study will run concurrently with an extensive RC drilling program targeted to explore these significant zones of oxide and sulphide mineralization. This drilling program is currently underway.
Background
The Moolart Well project is located within the Duketon Region Joint Venture approximately 100 kilometres north of Laverton in the Eastern Goldfields of Western Australia. Following completion of the transaction with Newmont Australia Ltd ("Newmont") expected in the third quarter of this year, the project will be effectively owned 59.2 % and managed by Regis.
With the creation of the Duketon joint venture in 1998, exploration activities increased predominantly focused on the existing gold projects in the area, in particular the Rosemont deposit. Newmont became manager in 2002 and subsequently discovered the Moolart Well mineralisation during a regional air core drilling program. Since that time exploration has focused predominantly on the Moolart Well project and the gold potential of the broader tenement package.
Laterite Resource
Previous manager Newmont established a JORC-compliant inferred resource in the Laterite zone over a north-south extent of 4km and down to an average vertical depth of 8m.

Oxide and Sulphide Intersections
Significant oxide and sulphide zone gold intersections exist beneath the laterite resource. None of these zones have been defined in detail, but the Directors believe several of these zones have the potential to be economic and the current drilling program is designed to test continuity to verify this assessment. Potential exists for a total resource of at least 1 million ounces of gold down to a depth of 100m vertical, including the 458,000oz already in the laterite zone. The resource potential of the project below 100m vertical depth is largely unknown and will be examined in selected areas during the current drilling program.
The oxide zone extends to 50-60m vertical depth, and broad spaced drilling on 100m sections has identified as many as seven potentially continuous mineralized zones striking obliquely through the property over a 4km strike. At least three of these oxide zones each have interpreted strike lengths approaching 1 kilometre (see attached figure). Significant oxide zone intersections are summarized in Table 2 below (all previously reported):

Only very limited drilling has been undertaken in the primary sulphide zone beneath the laterite and oxide mineralization. Notwithstanding this limited exploration, this drilling has discovered a number of mineralized gold zones at depth some of which are summarized in the table below. In addition, the drilling has delineated a broad zone of primary, low grade sulphide gold mineralisation which so far extends over nearly 1.5km of strike. This zone is open-ended, and will be important in understanding the origin of the gold mineralization in the area. The last three holes in Table 3 below indicate the tenor of this low grade zone.

Scoping Study Detail
The Scoping Study will examine the technical parameters and the economic potential of a mining development based on the Moolart Well gold project. The study will examine the various processing options for the existing laterite resource, and will include any oxide or sulphide resources that are defined from the current drilling program. In addition, the study will also look at the possible inclusion of known satellite resources into any development plan. The study will cover the following element headings:
- Laterite, oxide and sulphide resource evaluation and update; $\bullet$
- Conceptual open pit design; $\bullet$
- Crushing, screening parameters and $\bullet$
- Metallurgical characterisation of all ore types: ٠
- Conceptual process and plant design;
- Site engineering, hydrological and logistical evaluations; $\bullet$
- Financial modeling and option evaluation of development alternatives.
Moolart Well Drilling Program
A drilling program designed to further evaluate the Moolart Well mineralization has commenced, and consists of 25,000m of reverse circulation, aircore and diamond drilling. This program is part of a larger 70,000m program underway over the Duketon joint venture's extensive tenement holdings. In the Moolart well area this drilling is designed to test the continuity and attitude of the oxide and sulphide mineralization zones down to a vertical depth of 100m, as well as infill and extend the laterite resource. In addition, deeper drilling will seek to further outline the broad low-grade mineralized zone in the basement, known to have widths in excess of 50m and nearly 1.5km in length.
Cost
The cost of the Scoping Study and the associated resource/exploration drilling at Moolart Well are estimated to be \$1.4 million (100% level) and Regis' share will be funded from existing cash reserves. This expenditure will form part of Regis' obligation under the Heads of Agreement with Newmont to spend \$10 million on the Duketon joint venture properties.
Timing
Elements of the Scoping Study will commence immediately, and run concurrently with the drilling program referred to above. It is estimated the scoping study will be completed following the completion of the current project drilling, and is expected to be reported to the market early in the December quarter.
