Gold miners are currently popular with investors who want to generate real returns from the yellow metal. But when investing in miners it’s always worth considering what can go wrong. That’s especially true with companies which have just one operating asset. 

When I added Egypt-based gold producer Centamin to the SIF Folio in September, I acknowledged this risk, but I didn’t expect things to go wrong quite so quickly. 

On Friday, the shares fell 20%+ after the company said it had found signs of instability in one of the pit walls of the open-cast section of its Sukari mine. Fourth-quarter production is expected to fall by around 40% as a result, with an as-yet unknown hit to costs.

  • Temporary power provider Aggreko (LON: AGK)

  • Information, education and networking group Wilmington (LON: WIL)

  • Gold producer Centamin (LON: CEY)

Finally, here’s a list of the portfolio’s current holdings, as they stood during market hours on 5 October:


The two oldest stocks in the portfolio - Aggreko and Wilmington - are also its biggest losers. Perhaps this is unsurprising. Both were bought in December 2019, during the market euphoria which followed the Conservative’s decisive election win.
