This year the market capitalisation of Western Australian listed entities closed at A$362.7 billion, an increase of 3.7% effectively offsetting the decrease seen in 2024. During the past 12 months, we’ve observed some interesting commodity price movements and witnessed strong M&A activity within the mining and metals sector, which is sure to keep resource investors on their toes. The final quarter also saw the first impact of decreasing interest rates hitting the market. That, along with the increasing global geopolitical tensions, saw money return to the market, and a lot of it finding its way into the gold sector. Interestingly, without the last quarter push, we were on track for a further retraction of 3.8% in total market capitalisations from 2024 levels. It was an impressive final push to close the year out in positive territory.

In this special edition, we have delved into the topic of Unlocking the future of mining - How mining companies can build AI to achieve scale. The mining sector is changing – fast. Smart operations using artificial intelligence (AI), digital twins, and predictive analytics are revolutionising the industry. In particular, AI’s capabilities to mine insights from data at speed have the potential to drive massive efficiency gains and unlock significant value.
At this year’s Diggers & Dealers Mining Forum, we’re helping mining leaders take control of the change by exploring two sides of AI:
- The Opportunities – highlighting the positive outcomes AI can deliver: increased productivity and efficiency, reduced costs, improved safety, and smarter decision-making.
- The Challenges – the risks of inaction: being left behind by ignoring AI, not training staff to use AI safely, losing control over data, and gaps in cyber defence against deepfakes and other emerging threats. The critical need for powerful cybersecurity measures to protect against sophisticated attacks cannot be overstated.
