Project update - ASX:EVN
Evolution project briefing: no new drilling or resources; project timelines and growth targets
Evolution's 15 September 2026 investor briefing updates project status and timing at Cowal, Northparkes and Ernest Henry. It reports no new drill results and no new resource or reserve estimate; the resource and reserve tables are as at 31 December 2025. The new content is project progress, capital costs, first-ore dates and growth targets that the company describes as indicative or aspirational.

What investors must know
- The deck contains no new drill results and no new Mineral Resource or Ore Reserve estimate; its resource and reserve tables are as at 31 December 2025 and were first released on 1 May 2026.
- Group gold Mineral Resources are 1,300 Mt at 0.75 g/t for 31 Moz, up from 30 Moz a year earlier, and Ore Reserves are 460 Mt at 0.79 g/t for 12 Moz.
- Projects described as on track: Cowal Open Pit Continuation ($430M), Northparkes E22 block cave ($545M EVN share, first ore end FY30), Northparkes Coarse Particle Flotation ($75M EVN share, production FY28 H2) and Ernest Henry Bert ($160M, first ore FY29).
- The Northparkes expansion study ($14M EVN share) covers pre-feasibility work on the MJH block cave and the E44, Major Tom and E51 open pits, plus concept studies on three block caves, and is due for completion in FY27.
- The Cowal Tier 1 pathway is a target, not a resource: slide 6 shows a -25% to +150% range in life-of-mine ounces with no data points, and the company says it does not yet have reasonable grounds to believe the aim will be achieved.
- Bert (about 6 ktpa Cu and 12 koz pa Au) and Greater Duchess (about 10 ktpa Cu and 5 koz pa Au from about FY30) are shown as production figures, with a footnote that they are indicative only and subject to studies, permits and approvals.

How the price reacted
News signal mixed, and on day 1 the stock moved 0.0% against the gold index (XGD). After 20 trading days: -1.7% against the XGD.
From the last close before the market could trade on it ($13.55 on 14 Sep 2026), with day-1 volume 2.1x the 20-day average.
EVN's past price-sensitive news
After 9 earlier announcements, EVN rose on day 1 5 times and fell 4 times - an average move of -0.8%.
No share price reactions to earlier news are on record for this company, so no pattern can be drawn. The shares closed at A$13.55 on 14 September and were A$13.02 at the time of the supplied data, a fall of about 3.9%. Over the same period the XGD fell about 3.6%, GDX 13.3% and GDXJ 18.1%, so the move looks closer to the sector than to this briefing. The day-one reaction to the 15 September release is not supplied.

The market it landed in
| Market | On the day | Now | Since |
|---|---|---|---|
| Gold (US$/oz) | US$4,352 | US$3,886 | -10.7% |
| Gold (A$/oz) | A$6,085 | A$5,737 | -5.7% |
| Copper (US$/lb) | US$6.33 | US$6.09 | -3.8% |
| AUD/USD | 0.7152 | 0.6774 | -5.3% |
At the 14 September close, gold was US$4,351.9/oz (A$6,084.87/oz) and copper US$6.33/lb. The latest supplied prices are gold US$3,886.3/oz (A$5,737.08/oz) and copper US$6.09/lb, with AUD/USD at 0.6774 after falling 5.3%. At A$5,737/oz, spot remains far above the A$1,717/oz AISC in DrillScore's database for the June 2026 quarter, so the margin picture is still wide after the fall. The deck states no price deck, so no spot-versus-assumption comparison is possible. Copper is up 19.7% on a year ago, which supports the Northparkes and Ernest Henry copper growth case. Sector mood turned sharply negative after the release: GDX fell 13.3%, GDXJ 18.1% and COPX 19.1%, while the US dollar index rose 4.0% and the 10-year yield rose to 5.154%.
Against EVN's own history
DrillScore holds no earlier gold or copper intercepts for this company, so there is no drilling history to compare. No capital raisings are on record. The last analysed announcements were the FY26 results on 19 August 2026 (record A$1,475m profit, A$1,347m cash, 21.0c final dividend, and FY27 AISC guided higher) and the Carnaby acquisition on 27 July 2026. This deck adds no new cash, guidance or production figures to that history.
Risks & caveats
- The Cowal Tier 1 and life-of-mine upside depends on discovery drilling, studies and approvals that are not yet complete (Mod 2 approvals are in progress).
- Greater Duchess depends on the Carnaby acquisition, which remains subject to Carnaby shareholder, court and regulatory approvals.
- Production figures for Bert, Greater Duchess and the Northparkes expansion are indicative and not backed by a JORC basis in this document.
- Gold and copper prices have moved sharply since the release; gold is down about 5.7% in A$ terms and silver about 22.7% in US$ terms.
- Several projects are early stage (E22 box cut and decline, Bert portal and early works), so first-ore dates carry execution risk.
What's next
- Northparkes expansion study completion (pre-feasibility and concept studies) - FY27
- Cowal Mod 2 approvals (shown as Mod 21 on slide 7), in progress - not stated
- Cowal integrated business case and incremental investment decisions - FY28+
- Northparkes Coarse Particle Flotation production (recovery uplift about 2% Cu and Au) - FY28 H2
- Ernest Henry Bert first ore (7-year life) - FY29
- Northparkes E22 block cave first ore (9-year life) - End FY30
- Greater Duchess production (indicative, subject to Carnaby acquisition and approvals) - from about FY30
- Southern Lake Protection Bund and infrastructure relocation at Cowal - FY27 Q1
- Carnaby acquisition completion (subject to approvals) - not stated
Questions worth asking
- What JORC basis and Competent Person sit behind the Bert, Greater Duchess and regional copper production figures?
- When will the FY27 Northparkes expansion studies report, and what decisions and capital will they require?
- What discovery drilling is planned at Cowal (E41, Oban corridor, GR), and when will results be reported?
- How do the FY27 AISC guidance increase and lower gold prices affect margins at Cowal and Northparkes?
- What are the timing, funding and conditions of the Carnaby acquisition and Greater Duchess development?
What it means
For someone following Evolution, this briefing mainly shows where the company's projects stand. Open Pit Continuation, E22, Coarse Particle Flotation and Bert are described as on track, with first ore or production dates running from FY26 to FY30. It contains no new drilling or resource numbers, so the reported resource and reserve base is unchanged. The growth story (Cowal Tier 1, the Northparkes expansion and Greater Duchess) is still at study or aspiration stage, and the company says it does not yet have reasonable grounds for the Cowal aim. Gold and copper prices and miner shares have fallen since the release, but that move is sector-wide rather than specific to this news. The studies, approvals and FY27 cost guidance will matter more than this briefing alone. This is general information, not a recommendation.
