Taking a Shares and Shares ISA from £20,000 to £1m is formidable however theoretically doable. For instance, if a median progress price of 12% a 12 months might be sustained for 35 years, a seven-figure portfolio would consequence.
In truth, since September 2020, the share worth of the FTSE 100’s Endeavour Mining (LSE:EDV) has grown by a median of 13.4% a 12 months. If that price held regular, somebody might grow to be an ISA millionaire inside 32 years.
Nonetheless, a double-figure progress price is the exception quite than the norm. And previous efficiency shouldn’t be relied upon to foretell future returns.
An asset for unsure occasions
However Endeavour, one of many world’s main gold producers and the most important in West Africa, has achieved this feat on the again of hovering costs. Throughout occasions of financial uncertainty, traders are inclined to swap different monetary property for gold.
Because the desk beneath exhibits, the common worth acquired by the group throughout the second quarter of 2025 was 62% greater than within the final quarter of 2023. Over this era, prices have additionally risen however much less rapidly. The group claims to have the fourth-lowest all-in sustaining price within the business (AISC). The result’s greater earnings and a hovering share worth.
In 2024, by way of a mixture of share buybacks and dividends, Endeavour reckons it returned $251 to shareholders for each ounce of gold it produced. For the primary half of 2025, the equal determine was $338.
Taking benefit
To attempt to capitalise on this curiosity within the treasured steel, the World Gold Council, the commerce physique for the business, has made a documentary known as Elton John: Touched by Gold. In the course of the movie, the well-known singer describes the steel as “timeless” in addition to representing one thing that’s “inspirational, awe-inspiring and joyous”.
Anybody who has invested in Endeavour over the previous few years will in all probability agree with Sir Elton. However I doubt whether or not a 26-minute “unique entry” documentary that includes numerous gold boots, glasses, and jewelry – in addition to his assortment of gold discs — could have a lot of an impression on costs. Economists reckon international financial institution demand and inflation, notably within the US, could have extra of an affect.
However there are challenges that Endeavour should take care of. Because the chart beneath exhibits, costs might be risky. If gold begins to fall, there’s more likely to be a major pullback within the group’s share worth.

As well as, mining is operationally difficult, notably in rural Africa the place its principal property are situated. Currencies on the continent can even fluctuate considerably and, in the event that they go within the flawed course, might adversely impression earnings.
Wanting forward
Nonetheless, in the intervening time, there’s no signal of a slowdown in gold costs and most observers imagine the rally’s not over but.
The present (26 September) worth is round $3,750. And because of geopolitical issues, tensions between President Trump and the US Federal Reserve, and “strong” central financial institution purchases, UBS is predicting $3,800 by the tip of 2025 and $3,900 by mid-2026.
Deutsche Financial institution is extra bullish and reckons it might break by way of the $4,000-barrier someday in 2026. Trade specialists seem to agree that present market situations make a pointy correction unlikely.
On this foundation, as a long-term hedge in opposition to international uncertainty, I reckon Endeavour Mining is a inventory to think about.
