Juukan Gorge and the Limits of Legal Compliance.
Rio Tinto destroyed 46,000 years of heritage at Juukan Gorge, and it was entirely legal. That is the most important fact about it.
By Neil Fairburn · Director, Cultural Heritage Risk Management Ltd
On 24 May 2020, Rio Tinto destroyed two rock shelters at Juukan Gorge in the Pilbara to expand an iron ore mine. The shelters held 46,000 years of continuous occupation and deep significance for the Puutu Kunti Kurrama and Pinikura people, the Traditional Owners. The company had the legal right to do it. That is the single most important fact about the event, and the reason it reshaped cultural heritage management across the mining sector.
What was lost, and what was known
This was not a case of hidden significance. Rio Tinto had funded the archaeology itself. Excavation recovered around 7,000 artefacts, including a 4,000-year-old length of plaited human hair that DNA later tied directly to living Traditional Owners. The company's own archaeological report identified one of the shelters as being of the highest archaeological significance in Australia. The Parliamentary inquiry that followed found that preservation options existed and that the company understood the value of what it held. The destruction was legal. It was not inevitable.
How something so significant could be destroyed lawfully
The approval ran under Section 18 of the Western Australian Aboriginal Heritage Act 1972. Consent to disturb the site had been granted years earlier, and the Act gave Traditional Owners no effective mechanism to reopen that consent as the site's significance grew through later excavation. The Joint Standing Committee on Northern Australia, in its interim report titled “Never Again”, concluded that the legislation had failed, making the destruction of Indigenous heritage not only legal but almost inevitable. Legal compliance, in other words, certified the paperwork. It did not protect the heritage, and it did not protect the company.
What the standards now expect
The sector's response has hardened around a simple principle: a permit is not consent, and consent is not a signature obtained once and banked. The ICMM Mining Principles frame this through their performance expectations. Under Principle 3, members are expected to obtain the free, prior and informed consent of Indigenous Peoples where a project is likely to cause significant adverse impacts to critical cultural heritage, and to treat that consent as an ongoing relationship rather than a one-off transaction.
Around those commitments sits the ordinary machinery of good practice: proactive mapping of tangible and intangible heritage with the rights-holders themselves, a Cultural Heritage Management Plan embedded in the environmental and social management system, a chance finds procedure that actually stops work, training so that operators and contractors can recognise and respond to heritage on the ground, and third-party verification that tests whether any of this exists in practice rather than only on paper. None of it is mysterious or unusual. Juukan Gorge happened despite most of it being well understood at the time.
The real lesson
The cost of getting this wrong is not a fine. In the months after Juukan Gorge, Rio Tinto's chief executive and two senior executives left the company, investors publicly demanded accountability, and the firm's social licence to operate took damage that money could not quickly repair. The inquiry's conclusion was blunt: this was an incident waiting to happen, and other resource companies should take note.
For anyone managing a project with heritage exposure, the lesson is this. Legal compliance is the floor, not the defence. A Western Australia Section 18 approval, or its equivalent anywhere in the world, tells you that you are permitted. It does not tell you that you are safe, that the evidence still holds, or that the people whose heritage is at stake have genuinely consented. Heritage managed as a box to tick will, sooner or later, produce a Juukan Gorge. Heritage managed as a governed risk across the project lifecycle, with real consent and evidence that survives scrutiny, is how a project keeps both its heritage and its licence to operate.
