Investing regularly in quality UK shares has an almost magical quality when given enough time. The mathematics of compounding mean that even modest monthly contributions can quietly snowball into a life-changing pool of wealth and, with it, a substantial passive income stream.
What an index fund delivers
The simplest starting point for a new investor is an index fund tracking the FTSE 100. Investing £500 a month at the long-run average of 8% annually over 30 years produces a chunky nest of around £745,179. And when following the 4% withdrawal rule, that translates into an income stream of £29,807 a year.
That’s a genuinely impressive outcome. But patient, selective stock-pickers could potentially do even better.
Can one stock change the maths entirely?
Atalaya Mining‘s (LSE:ATYM) delivered an average annualised return of 25.3% over the last decade – one of the standout performances in the entire UK market.
An investor drip feeding £500 a month into this mining enterprise at that rate over the past 10 years would now be sitting on around £266,268 today. Not bad. But here’s where it gets exciting.
If that compounding rate continues for just a few more years, that portfolio would grow to reach £1,649,350 – enough for a £65,974 second income. That’s more than double what index fund investors could earn in almost half the time.
So is it realistic or is it too good to be true?
Can Atalaya keep delivering?
Sustaining a 25.3% annualised return for another seven years is a pretty challenging feat for any business. And while it certainly isn’t impossible, Atalaya will need some powerful external tailwinds to get there. Fortunately, it might have some.
As a quick reminder, Atalaya is a copper mining enterprise operating in Spain. And the red metal could be a winning ticket to more wealth for long-term investors.
Electrification, electric vehicle adoption, grid expansion, and the global energy transition are all driving structural demand for copper. So much so that demand’s already outstripping supply – a trend that’s expected to accelerate over the next decade.
Despite ongoing efforts, the hunt for new significant copper deposits is proving quite tricky for the entire sector. And it’s why copper prices have been on an upward trajectory since the start of 2024, rising by over 60% already.
However, even with limited discoveries, other copper producers are finding ways to ramp up production volumes to capitalise on the commodity price momentum. And if demand were to suddenly fall in the near term due to slower industrial demand in the wake of widespread economic slowdowns, the copper price might start to reverse.
Put simply, while the emerging tailwinds are powerful, Atalaya’s nonetheless a highly cyclical business – a structural risk that investors must carefully consider.
Worth watching closely
The numbers tell a compelling story. For investors willing to do the research and take a long-term view, UK shares like Atalaya offer a genuine pathway to the kind of passive income that most people only dream about.
Obviously, as with every investment, there are no guarantees. But looking at Atalaya, the opportunity appears very real. That’s why for investors looking to build long-term wealth and gain exposure to a mission-critical sector, this mining business is worth a closer look.
