Overview
The gold mines beneath Casterly Rock are the traditional source of House Lannister's fabled wealth — though the novels and the television adaptation give notably different accounts of how much gold, if any, is left in them by the story's present day.
History
Casterly Rock's gold has underpinned House Lannister's wealth and standing for generations, to the point that the family's riches are treated as proverbial across Westeros.
Workings
Neither the novels nor the show detail the mines' physical workings; both instead focus on what the gold means for House Lannister's finances and reputation.
Canon & adaptations
The two versions of the story disagree sharply here. The television series has Tywin Lannister privately admit to his daughter Cersei that the family's 'last working mine dried up three years' earlier, revealing the Lannisters' famous wealth to be a bluff propped up by loans from the Iron Bank of Braavos. The novels never make this claim — George R. R. Martin has stated directly that Casterly Rock's mines are not tapped out; the book-canon problem is instead that the Lannisters have been spending gold faster than the mines can produce it to fund their wars, a debt crisis rather than a resource exhaustion.

Recorded claims
Each claim is marked with its basis — explicit canon, MineArchive inference, adaptation only, or fandom interpretation — and attached to the source(s) below. Where tellings disagree, both are kept.
- The television series states the Lannisters' gold mines ran completely dry three years before the relevant season, per a private admission from Tywin to Cersei Lannister. (adaptation only, medium) 1
- The novels do not depict the mines as exhausted; the Lannisters' financial trouble in the books is that their spending outpaces what the still-productive mines bring in, not that the gold has run out. (MineArchive inference, low) 2
