“Two decades ago, Atlas Copco, a Swedish mining technology company, was the largest holding in LTGG. At the time, around a quarter of the portfolio was invested in mining and resource companies, several of which went on to deliver very substantial returns. We have recently been revisiting this domain and our logic is simple. While AI token use can scale exponentially, the essential physical inputs to the AI buildout can only expand linearly; indeed, in areas such as copper, supply is barely responding to surging demand. The likes of Zijin Mining and Freeport-McMoRan deserve some more research work from us, as do MP Materials (America’s only fully-integrated rare-earth producer) and Cameco, a leading uranium supplier.”
