Greatland gets WA environmental approval for Havieron, completing both state and federal primary approvals
Greatland says the WA Minister for the Environment has given the state primary approval for its Havieron gold-copper project, following the federal approval of 24 April 2026. With both primary approvals in hand, the company is targeting a Final Investment Decision in the June 2026 quarter. The release gives no capital cost, funding plan or conditions attached to the approval.

What investors must know
- Both primary environmental approvals for Havieron are now received: the Commonwealth approval (EPBC Act, 24 April 2026) and the WA Part IV approval (25 May 2026).
- The WA approval is subject to specified environmental conditions, which the announcement does not list.
- The company targets a Final Investment Decision for Havieron in the June 2026 quarter, with the approvals described as allowing it to advance towards that decision.
- Early works and tendering for critical path packages are already under way, including boxcut tunnel installation, underground development and blind bore construction preparation.
- The announcement says Havieron could produce around 270koz of gold a year at steady state with a 17-year initial mine life, but gives no study reference or capital cost.
How the price reacted
News signal positive, and on day 1 the stock moved -1.7% against the gold index (XGD). After 20 trading days: -1.9% against the XGD.
From the last close before the market could trade on it ($13.92 on 25 May 2026), with day-1 volume 0.9x the 20-day average.
GGP's past price-sensitive news
After 9 earlier announcements, GGP rose on day 1 4 times and fell 5 times - an average move of +2.6%.
DrillScore has no recorded share price reactions to earlier price-sensitive news from Greatland, so no past reaction pattern can be drawn. The share price fell from A$13.92 before release to A$10.36 now, a move of about 26%, over a period when gold, copper and copper miner funds also fell. The market context cannot be separated from this announcement's effect.

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$4,523 | US$3,886 | -14.1% |
| Gold (A$/oz) | A$6,328 | A$5,737 | -9.3% |
| Copper (US$/lb) | US$6.34 | US$6.09 | -4.0% |
| AUD/USD | 0.7157 | 0.6774 | -5.4% |
At release (22 to 25 May 2026), gold was US$4,523.2/oz (A$6,327.92/oz) and the AUD was US$0.7157. Since then gold has fallen to US$3,886.3/oz (A$5,737.08/oz) and the AUD to US$0.6774, while the US dollar index and 10-year yield have risen. A lower A$ gold price narrows margins against any Havieron cost base, but the release gives no cost or price assumptions to test against. Sector mood has weakened: GDXJ is down 11.3% and COPX down 16.9% since release, while the XGD is up 6.6%.
Against GGP's own history
DrillScore's database holds no drilling history for Greatland, so there is no earlier intercept to compare with. The March 2026 quarter reported cash of A$1,208.2m, no debt, 82,723oz of gold and AISC of A$2,056/oz. The 30 March 2026 resource update put Telfer at 8.0Moz. This approval is a permitting step and does not change those figures.
Risks & caveats
- The approvals are a permitting milestone, not a decision to build. The Final Investment Decision has not yet been made.
- The WA approval comes with environmental conditions that are not described in the announcement.
- No capital cost, schedule or funding plan for Havieron is given in this release, so the scale of the commitment cannot be judged from it.
What's next
- Final Investment Decision on Havieron - June 2026 quarter (targeted)
- Telfer life extensions, referred to as alongside Havieron development - not stated
Questions worth asking
- What is the capital cost of Havieron and how will it be funded between existing cash and debt?
- What are the specified conditions attached to the WA approval, and do any affect the schedule or cost?
- On what study is the 270koz a year and 17-year mine life based, and what are the lowest quartile cost assumptions?
- Will the Final Investment Decision still be made in the June 2026 quarter given the recent fall in gold prices?
What it means
This is a meaningful permitting milestone for Havieron, and it removes one of the approval hurdles ahead of a possible Final Investment Decision. It does not show what the project will cost, how it will be funded or what returns it will earn, and the WA conditions are not yet described. Investors following the stock should watch for the Final Investment Decision announcement, the capital cost and the conditions attached to the approvals.
