Quarterly Report
For the period ended 30 September 2004
OVERVIEW
The September quarter has been a particularly busy one for Rox, with two drilling programs, resource estimation and a pit optimisation study completed.
A RAB drilling program of 6,764 metres early in the quarter identified a number of targets which returned high-grade drill intercepts. Three of these targets at Bonnie Jean, Ballarat Menzies and Wedderburn were followed up with RC drilling (1,316 metres) later in the quarter. Disappointingly, the RC follow-up did not reproduce the high-grade hits from the earlier RAB drilling. The RAB drilling also identified a number of other lower grade targets which are yet to be tested by RC drilling.
The RC drilling program did produce a further high-grade intercept at Lady Shenton North, of 5 metres at 12.1 g/t Au from 5 - 10 metres depth. The intercepts at Ballarat Menzies were also of interest producing 5 metres at 1.81 $g/t$ Au from 10 - 15 metres depth and 5 metres at 1.44 $g/t$ Au from 40 - 45 metres depth.
The RC drilling also discovered a new nickel laterite zone west of Yunndaga, called Acacia Ridge, with high-grade nickel hits of 14 metres at 0.91% Ni, 0.17% Co and 15 metres at $0.76\%$ Ni, $0.17\%$ Co being recorded. The high cobalt values are particularly noteworthy. This is believed to be an extension of the large Highway nickel laterite deposit to the south.
Resource estimation using new drilling data increased the resource by $11\%$ to $170,900$ ounces contained gold, with 77% in the Measured and Indicated category. Pit optimisations of these new resources identified 24,000 ounces that could be profitably mined. The Company will continue to seek to expand resources and will concentrate on drilling high-grade targets beneath surface deposits in the coming quarters.
EXPLORATION AND DEVELOPMENT ACTIVITIES
RAB Drilling
Rox Resources Limited (ASX code RXL, "Rox") completed a RAB drilling programme of 145 holes totalling 6,764 metres in early August, testing soil anomalies on the Aspacia-Yunndaga Trend, the Eastern Mafic Trend (mainly targeting shallow gold workings) and the First Hit South RAB anomaly. Holes were sampled at 5 metre intervals and assayed for gold by Atomic Absorption Spectroscopy, except for smaller intervals at the end of holes.
Two new discoveries were made at Bonnie Jean and Ballarat Menzies, located SE of Lady Harriet (see attached map). Best results included:
| S7RB0052 | 13 metres [email protected] g/t$ Au from 20m depth (to EOH) at Bonnie Jean, |
|---|---|
| S8RB0004 | 10 metres [email protected] g/t$ Au from 15m depth at Ballarat Menzies, and |
| 1 metre [email protected]/t$ Au from 30m depth (to EOH), and | |
| FHRB0006 | 5 metres @ 12.8 g/t Au from 25m depth at Wedderburn (south of First |
| Hit pit) |
Other noteworthy results were:
| 58RB0001 | 5 metres [email protected] g/t$ Au from 10m depth at Ballarat Menzies, |
|---|---|
| 58RB0002 | 5 metres @ 2.31 g/t Au from 15m depth at Ballarat Menzies, |
| 58RB0005 | 5 metres @ 1.43 g/t Au from 10m depth at Ballarat Menzies, |
| FHRB0007 | 5 metres @ 2.49 g/t Au from 25m depth at Wedderburn, and |
| FHRB0008 | 10 metres @ 1.46 g/t Au from 40m depth at Wedderburn. |
Full drill results are shown in Table 1 and prospect locations are shown on Figure 1.
RC Drilling
An RC drilling program of 21 holes totalling 1,116 metres was completed during September, following up previous RAB and RC results at Bonnie Jean, Ballarat Menzies, Wedderburn and Lady Shenton North. All holes were drilled at inclinations of -60° to local grid east. Significant results returned from 5 metre composite samples (1 metre split assays are still awaited) were:
| LSRC0004 | 5 metres at 12.1 $g/t$ Au from 5m to 10m |
|---|---|
| 5 metres at 1.96 g/t Au from 20m to 25m | |
| LSRC0006 | 10 metres at 0.94g/t Au from 20m to 30m |
| BMRC0001 | 5 metres at 1.81g/t Au from 10m to 15m |
| 5 metres at 1.11g/t Au from 25m to 30m | |
| BMRC0006 | 5 metres at 1.44g/t Au from 40m to 45m |
Disappointingly the RC twin of the previous RAB hole at Bonnie Jean $(13m \otimes 9.9, g/t \wedge u)$ did not return any values greater than $0.2$ g/t Au. Full results are given in Table 2.
Rox also drill tested a likely nickel laterite zone west of Yunndaga, where no previous drilling had occurred. A line of 5 holes for 200m intersected significant nickel in every hole, with best results:
| YNRC0003 | 14 metres at 0.91% Ni, 0.17% Co or 1.59% NiEq, including |
|---|---|
| 2 metres at 1.39% Ni, 0.30% Co or 2.59% NiEq | |
| YNRC0001 | 15 metres at 0.76% Ni, 0.17% Co or 1.44% NiEq, including |
| 2 metres at $1.06\%$ Ni, 0.45% Co or 2.86% NiEq. | |
| (NiEq = Ni + 4 x Co, based on current metal prices) |
Drilling intersected both saprolitic material with very high cobalt values, and low magnesium siliceous material, similar to the Highway deposit to the south where Heron Resources Limited recently announced a resource of 85 million tonnes grading 0.72% Ni, 0.051% Co. Heron expect siliceous ore to upgrade to 1.5% Ni.
The high cobalt values in both intercepts, with very high nickel equivalent (NiEq) grades, and the styles of mineralisation are particularly attractive for future processing. Full drilling results are given in Table 3 and drill hole locations are shown on Figure 2.
Resource Estimation
Rox also completed a new resource estimate at Menzies (following its initial drilling programmes), which was used as the basis of a preliminary evaluation of mining options.
The results indicated an 11% increase in contained ounces of gold compared to the previous estimate, and an increase in confidence with approximately 77% of the resource now classified as Measured or Indicated, as shown in the table below at a lower cut-off of $1 g/t$ .
| Category | New | Previous | |||||

| Measured | 75,000 | 2.3 | 5,500 | 98,000 | 2.8 | 8,900 | |
| Indicated | 1,559,000 | 2.5 | 124,900 | 810,000 | 2.9 | 75,600 | |

| TOTAL | 2,128,000 | 2.5 | 170,900 | 1,734,000 | 2.8 | 153,600 |
Tables $4 \& 5$ show the results in more detail. Resource estimation methodology is described in Appendix 1.
Pit Optimisation
It was previously recognised that high-grade portions of the resources lying below the open pits may be amenable to exploitation by either underground mining or extensions/cutbacks to the existing open pits. Pit optimisations were run to evaluate how much might be extractable by open pit, to target any in-fill drilling required (particularly at the 86,000 ounce Yunndaga deposit), and to determine where the open-pit to underground transition might be for each deposit.
A series of gold prices ranging from A\$500/oz to A\$700/oz were used in the optimisations and it was assumed that contract mining and toll treatment would be the preferred path for development, as described in Appendix 2.
While the optimisations were run primarily as a tool to begin assessment of various development options, they showed that at a gold price of $A$575/\alpha z$ , 185,000 tonnes at a grade of $4.4$ g/t Au yielding 24,200 ounces may be profitably mined.
However, this is only a preliminary result, and more information will be needed before any definite statements about mining options can be made. For example, in-fill drilling of sparsely drilled areas may increase grades, while a portion of the optimised resources may not be able to be mined due to back-filling of open pits, previous unaccounted for underground mining and geotechnical issues.
Rox will continue to examine the alternatives, including underground mining and on-site treatment as a means of maximising the value of the remaining exploitable resources.

High-grade cuts were applied at different values for different deposits (see Appendix 3) depending on grade distribution statistics
Appendix 1: Resource Estimation Methodology
The Lady Shenton, Yunndaga and Lady Harriet resource estimates were undertaken by Resource Evaluations Pty Ltd, while First Hit and Selkirk were completed by Rox and audited by Resource Evaluations.
Resource estimates by Resource Evaluations Pty Ltd used Inverse Distance Cubed (ID3) grade interpolation, constrained by resource outlines based on mineralisation envelopes prepared using a nominal cut-off grade of $0.5$ g/t Au and a minimum down hole length of 3m. Block dimensions were 10m NS x 5m EW x 2.5m vertical with sub-cells of 5m x 2.5m x 1.25m.
Drill data were from the drill database provided by Paddington Gold Pty. Ltd., which was checked and validated by IO Digital Pty. Ltd. The database included exploration/resource definition drilling as well as grade control drilling. Some additional holes drilled recently by Rox were also included. Holes were mostly drilled by reverse circulation (RC) with down hole sampling on 1m and 2m intervals. For resource estimation, samples were composited either to 1m or 2m intervals (depending on the deposit).
A search ellipse of $30m \times 30m \times 3m$ radius was used for the first pass of grade interpolation followed by a second pass at 60m, and a third pass at 120-150m. The search ellipse was orientated along the dip and strike of mineralisation. Bulk density values of 1.9 t/m3, 2.3 t/m3 and 2.75 t/m3 were used for oxide, transitional and fresh material respectively. No dilution was modelled.
Resources were classified as Indicated if the drilling pattern was closer than or equal to 20m x 20m, with Inferred classified from this limit up to $100m \times 100m$ (but only if geological continuity was reasonable).
High-grade cuts were 20 g/t Au for Lady Harriet, 25 g/t Au for Lady Shenton, and 30 g/t Au for Yunndaga.
For the resource estimates carried out by Rox, the parameters used were identical to those above except for:
- Sample Quality Control, where examined, showed good repeatability between duplicate samples.
- Minimum down hole interval was 2m with maximum internal dilution of 2m for the 0.5 g/t Au grade envelope.
- Block size of 5m NS x 5m EW x 2.5m vertical was used, with sub-blocks of 2.5m x 2.5m x $1.25m.$
- High-grade cuts were 60 g/t Au for Selkirk, and 25 g/t Au, 32 g/t Au and 40 g/t Au for three different domains modelled in the First Hit deposit.
Appendix 2: Pit Optimisation Parameters
The optimisations were undertaken by Intermine Consultants who used the following mining, transport and milling costs, based on industry "standard" costs and/or enquiry. The royalty scheme was the 1% NSR payable to Paddington Gold. Input from a recent geotechnical review by Snowden Mining Industry Consultants was used to determine pit slopes etc.
| Milling | \$20/t (estimate of toll milling cost at Paddington or Davyhurst) |
|---|---|
| Transport | $$7/t$ (estimate based on use of 100km bitumen road to Paddington @ |
| $$0.07/t km$ , or 63km gravel road to Davyhurst @ \$0.11/t.km) | |
| Administration | $$1/t$ (estimate) |
| Mining | \$1.50/t (estimated for ore and/or waste) |
| Recoveries | 90% mining, 92% metallurgical (data from previous operator) |
