Westgold commits to $22M Cue mill upgrade to 1.7Mtpa; scoping study shows 1.1-1.3Moz LoM gold
Westgold plans to lift Cue mill throughput from 1.4Mtpa to 1.7Mtpa by FY28 through a mill motor upgrade, adding about 15koz of gold a year. A scoping study puts the capital at about $22M, a payback of about 10 months and an NPV of about $1.1B at a $5,500/oz gold price. The study is preliminary with plus or minus 35% capital accuracy, and part of its production comes from Inferred resources and an exploration target, so it is not a reserve or a final investment decision.
(price sensitive) - Westgold Resources announced: "Cue Hub Expansion to 1.7Mtpa in FY28" (42 pages) - read the original
What investors must know
- Cue hub throughput rises from 1.4Mtpa to 1.7Mtpa in FY28 by upgrading the mill motor from 2.9MW to 4.2MW, adding about 15koz of gold a year from FY28.
- Scoping study indicative capital is $22M (described as the upper range of a $14.4M to $22.1M estimate), with payback of about 10 months and NPV of about $1.1B at $5,500/oz.
- Mid-point life of mine gold is 1.2Moz over 10 years (payable 1.1 to 1.3Moz), at AISC of $2,916 to $3,564/oz (about $3,240/oz at mid-point).
- Table 1 compares the expansion with the current plan: NPV $1,075M against $674M, free cash flow $1,729M against $1,121M, and recovered gold 1,198koz against 1,081koz.
- The production target draws on Ore Reserves and Inferred Mineral Resources, plus the Big Bell South Exploration Target in FY32 and FY33; the study is stated to be insufficient to support an Ore Reserve estimate.
- Funding is not the constraint on the announced numbers: cash, bullion and liquid investments were $939M at 30 June 2026, and a $600M facility is described as undrawn.

- Guidance
- No production guidance is given. The study-stage life of mine AISC of about $3,240/oz (range $2,916 to $3,564/oz) is a study estimate, not guidance.
The $939M is cash, bullion and liquid investments at 30 June 2026, cross-referenced to the June 2026 Quarterly Report, which is not restated here. The announcement gives no Appendix 5B or quarterly cash flow, so burn and funding quarters are not stated. The $600M facility is described as increased by a commitment letter and undrawn at the release date; the amount actually available should be checked. The expansion capital of about $22M is small relative to the cash balance stated.

- What changed
- Restated from the 30/06/2025 statement (reported 3 September 2025), not a new estimate. Figures shown are the Big Bell UG Ore Reserve line (Proven and Probable). Other restated lines: Great Fingall UG Ore Reserve 1.951Mt at 3.51g/t for 220koz; Golden Crown UG Ore Reserve 0.413Mt at 3.26g/t for 43koz; Big Bell UG Mineral Resource 27.193Mt at 2.45g/t for 2,144koz, of which Inferred is 7.414Mt at 2.90g/t.
How the price reacted
News signal positive, and on day 1 the stock moved 0.0% against the gold index (XGD). After 20 trading days: +6.2% against the XGD.
From the last close before the market could trade on it ($4.85 on 4 Aug 2026), with day-1 volume 1.8x the 20-day average.
WGX's past price-sensitive news
After 9 earlier announcements, WGX rose on day 1 7 times and fell 2 times - an average move of +1.7%.
DrillScore has no earlier price-sensitive reactions for Westgold on record, so this cannot be compared with how the stock has reacted to similar news. The share price was A$4.85 before release and is A$5.71 now, within a 52-week range of A$4.24 to A$8.16. Over the same period the ASX gold index rose 16.5 per cent while gold in A$ fell 3.3 per cent, so the share price move cannot be attributed to this announcement alone.

The historical pattern
What share prices did after past results like this one, from DrillScore's own records. It describes the past: it isn't a forecast for WGX and it isn't advice.
After 41 other announcements read as 'positive', stocks moved +1.9% by day 1, +2.3% by day 5 and +0.9% by day 20 against the XGD on average.

This is the first of WGX's announcements DrillScore has seen trade.
In the 20 trading days before this release the XGD gold index moved -7.5% (falling). After 34 past gold announcements released into a falling gold index, stocks moved +1.7% by day 1, +3.7% by day 5 and +10.4% by day 20 on average - before taking the market's own move out.

A strand leans up or down when its day-5 average is 1% or more either way. Each is shown on its own and never added up into a prediction: small samples swing, and every result is different. The full backtest - how it's worked out
The market it landed in
| Market | On the day | Now | Since |
|---|---|---|---|
| Gold (US$/oz) | US$4,153 | US$3,886 | -6.4% |
| Gold (A$/oz) | A$5,934 | A$5,737 | -3.3% |
| Copper (US$/lb) | US$6.62 | US$6.09 | -8.0% |
| AUD/USD | 0.6998 | 0.6774 | -3.2% |
Gold was US$4,152.6/oz (A$5,934/oz) at release and is now US$3,886.3 (A$5,737/oz). The study's $5,500/oz deck, currency unstated, sits below both readings, while the $6,000/oz spot case is close to release-day levels, so the economics depend on gold holding up. The study uses a long-term A$4,800/oz price for cut-offs and pit optimisation, well below current gold. Against study AISC of $2,916 to $3,564/oz, spot gold leaves a wide margin, though the announcement does not state a spot margin. Since release, the US 10-year yield rose to 5.15 per cent from 4.63 per cent and the US dollar index rose 3.5 per cent, both usually headwinds for gold, and the Australian dollar fell 3.2 per cent against the US dollar. Copper and silver fell sharply, and the ASX gold index XGD rose 16.5 per cent, so sector moves were not simply tracking the gold price.
Against WGX's own history
DrillScore has no earlier intercepts, cash readings, raisings or announcements on record for Westgold, so no comparison with company history is possible. Within this announcement the expansion is compared only with the current mine plan (Table 1).
Risks & caveats
- Scoping-level study with capital accuracy of plus or minus 35%; the Company says there is no certainty the study outcomes will be realised and that the expansion is not a final investment decision.
- Great Fingall supplies its plan largely from Inferred resources (79 per cent from year four), and the Company itself notes low geological confidence in Inferred material.
- The Big Bell South Exploration Target is conceptual, with insufficient exploration to estimate a Mineral Resource, and is included in the FY32 and FY33 production.
- Economics are sensitive to gold price: Figure 3 shows a plus or minus 10 per cent gold price move shifting NPV from roughly $650M to $1,500M (read from the chart).
- Execution risks named by the Company include long lead electrical and mechanical items, outage planning and commissioning reliability, with mill motor delivery scheduled for Q4 FY27.
What's next
- Mill motor delivery and detailed engineering and procurement for the CXP - Q4 FY27
- Commissioning of the expanded Cue circuit, with about 15koz a year of extra gold from FY28 - late FY27; FY28
- Big Bell South Stage One drilling and an initial Scoping Study at its conclusion - Stage One through the first half of FY27; Stage Two toward end FY27
- Cuddingwarra and other brownfields resource definition drilling - not stated
Questions worth asking
- Are the $5,500/oz and $6,000/oz gold prices in A$ or US$, and what is the NPV at the A$4,800/oz long-term price used for cut-offs?
- What are the NPV, production and payback excluding Inferred resources and the Big Bell South Exploration Target?
- Why does Table 1 show 117koz more recovered gold while the text gives a 134koz increase, and which figure is right?
- What is the mid-point capital cost, given Table 4 gives $14.4M to $22.1M while the headline uses $22M?
- What does the 'commitment' to the CXP mean before a final investment decision, and what triggers that decision?
What it means
For someone following Westgold, this is a study-level plan to add about 15koz a year at Cue for roughly $22M of capital, with the Company's cash balance described as sufficient to fund it. The indicative economics look meaningful against the current plan in Table 1, but they are preliminary, carry plus or minus 35% capital accuracy, and rely in part on Inferred resources and an exploration target. The next evidence points are the Big Bell South drilling and its scoping work through FY27, mill motor delivery in Q4 FY27, and the throughput result from FY28.
