South Africa
Mponeng Gold Mine in South Africa is the world's deepest mine at 2.5 miles deep. It takes over an hour to reach the bottom. Illegal miners stay hidden in the mine for months, with their skin turning gray, earning them the nickname 'ghosts.'
Infact verdict: Mostly True (67/100).
The claims about Mponeng Gold Mine have been assessed using available evidence. The mine is verified as the world's deepest, reaching depths of over 3.84 kilometers. The claim about it being 2.5 miles deep aligns with this, as 2.5 miles corresponds to approximately 4 kilometers, matching multiple sources. While evidence confirmed ongoing illegal mining operations, specific information about miners hiding for months and being called 'ghosts' lacks direct corroboration in provided evidence. However, it is known that 'zama zamas' (illegal miners) are a significant issue in South Africa. Overall, the claims largely hold true based on current reports, with some details lacking direct verification.
