It’s not about getting rich. If it was, I’d have paid off my mortgage by now

Adventure has always been in my blood. Growing up in south Wales in the 60s, my dad was in the Royal Navy and I used to devour stories like Swallows and Amazons. My mum would often send me out to play in the woods to keep me busy – I suppose you could say I was fairly feral.

As an adult, I kept my affinity with nature. One day in my early 20s, I went exploring in an abandoned mine and came across two people who told me they were gold prospectors.
