Taking a Shares and Shares ISA from £20,000 to £1m is formidable however theoretically doable. For instance, if a mean progress fee of 12% a 12 months could possibly be sustained for 35 years, a seven-figure portfolio would end result.
In truth, since September 2020, the share value of the FTSE 100’s Endeavour Mining (LSE:EDV) has grown by a mean of 13.4% a 12 months. If that fee held regular, somebody might turn into an ISA millionaire inside 32 years.
Nevertheless, a double-figure progress fee 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 belongings for gold.
Because the desk beneath reveals, the typical value obtained by the group in the course of 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 shortly. 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 value.
In 2024, by 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 $338.
| Quarter | Realised gold value ($/oz) | AISC ($/oz) |
|---|---|---|
| This fall 2023 | 1,945 | 947 |
| Q1 2024 | 2,041 | 1,186 |
| Q2 2024 | 2,287 | 1,287 |
| Q3 2024 | 2,342 | 1,287 |
| This fall 2024 | 2,590 | 1,141 |
| Q1 2025 | 2,783 | 1,129 |

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 referred to as Elton John: Touched by Gold. Through 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 most likely agree with Sir Elton. However I doubt whether or not a 26-minute “unique entry” documentary that includes a lot of gold boots, glasses, and jewelry – in addition to his assortment of gold discs — may have a lot of an affect on costs. Economists reckon world financial institution demand and inflation, significantly within the US, may have extra of an affect.
However there are challenges that Endeavour should cope with. Because the chart beneath reveals, costs may be unstable. If gold begins to fall, there’s more likely to be a major pullback within the group’s share value.

As well as, mining is operationally difficult, significantly in rural Africa the place its principal belongings are situated. Currencies on the continent can even fluctuate considerably and, in the event that they go within the mistaken course, might adversely affect earnings.
Trying forward
Nevertheless, in the intervening time, there’s no signal of a slowdown in gold costs and most observers consider the rally’s not over but.
The present (26 September) value 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 the $4,000-barrier someday in 2026. Business consultants seem to agree that present market circumstances make a pointy correction unlikely.
On this foundation, as a long-term hedge towards world uncertainty, I reckon Endeavour Mining is a inventory to contemplate.
