VanEck's Gold Miners ETF (GDX) climbed about 95% last year. Investors are now looking beyond consumer-facing AI apps to the hardware, metals and mining companies that will underpin large-scale AI deployments — including a range of Australian miners already rolling out digital twins, autonomous haulage and maintenance analytics.

Why metals matter to AI buildout

AI at scale needs more than chips and code. It needs power, networking gear and a steady flow of metals that go into processors, servers and data-centre interconnects. The World Gold Council has noted rising technology demand for gold, which is already a meaningful slice of global supply for some end-uses.

Gold is a corrosion-resistant conductor used in high-reliability electronics. Silver plays a complementary role: it is commonly used in photovoltaic cells and high-speed interconnects. Industry commentary has also warned that reserves and refining capacity could tighten as hardware demand scales.

Data-centre growth feeds the demand loop. Major banks and research groups project a substantial rise in global power demand from data centres by 2030, which implies a larger fleet of servers and networking kit. More servers mean more connectors, bonding wire and plated components that rely on gold and silver.

How miners and technology meet

Mining companies aren't just digging and shipping ore anymore. They're deploying machine learning for exploration and to run sites more efficiently.

Industry surveys list concrete applications across the sector: predictive maintenance to avoid costly downtime, autonomous haulage, digital twins to model process flows, and AI-driven exploration to prioritise drill targets.

Some large producers are already tying those capabilities to their operations, and a range of Australian miners are deploying digital twins, autonomous trucks and maintenance analytics. Those tools aim to lower unit costs and shorten time between discovery and production.

That matters for investors because metals that go into AI hardware face two linked forces. First, demand from technology can scale quickly when cloud providers and chip foundries expand. Second, supply-side constraints—mine life, permitting and refining capacity—can take years to address. When demand jumps faster than supply, prices rise and mining equities tend to amplify those moves.

Where investor returns could come from

There are three practical ways investors can play the tie between AI and metals:

  • Physical metal exposure — bullion or allocated metal holdings provide direct commodity exposure.
  • Mining company shares — equities can benefit when producers cut unit costs through digital tools and expand output.
  • Funds and ETFs — equity funds such as VanEck's Gold Miners ETF (GDX) concentrate mining exposure and can act as leveraged plays on the metal because miners' margins often expand faster than the metal price.

That combination — rapidly scaling hardware demand from data centres and chip foundries plus slow-moving supply responses at mines and refineries — is what can push metal prices and mining equities sharply higher. Watch cloud providers' capacity announcements, chip-foundry expansion plans and miners' next quarterly production updates; those are the near-term triggers likely to move prices and stocks.
