Where sources disagree, MineArchive keeps both accounts rather than picking one; where a fact could not be settled, the record says so. 7 such claims on 3 records. All regions.

• The quarries closed in 1958. (disputed)

Cononish Mine

• A January 2009 report, made before large-scale operations resumed at Cononish, describes mining equipment including tipper trucks and an excavator still standing underground, along with visible gold in the rock and a narrow older adit that leads out behind a waterfall. (uncertain)
• Mining at Cononish effectively stopped at the end of September 2023 when staff were laid off, and the site went onto care and maintenance with a core team retained for environmental monitoring. Reporting in March 2025 said a South African group had bought the mine and intended to recapitalise it and restart production. MineArchive has not confirmed whether production has in fact resumed. (uncertain)
• A monitoring report of June 2023 rated eight of the mine's planning conditions red and five amber. Among them was the settlement pond, still unrepaired after fifteen months of promised work, which Parkswatch Scotland reports had leaked polluted water into the River Cononish from the start. (uncertain)

Pirnhall Colliery

• All Pirnhall's electricity was supplied from Bannockburn Colliery. (disputed)
