Open questions: East Lothian

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 5 records. All regions.

Bankton Colliery

• The BGS mine-plans catalogue holds a Mining Remediation Authority abandonment plan titled 'Bankton' (catalogue 11914, Four Feet, dated 1933); the catalogue gives no location and the plan's details do not clearly tie it to this working, so it may belong to another of the same name. (uncertain)

Elphingstone Colliery

• Mining Remediation Authority abandonment plans titled 'Elphingstone' are dated 1882 (Five Foot), 1907 (Great) and 1929 (Splint, catalogue 11609); the 1929 plan may bear on the unestablished closure date. (uncertain)

Limeylands Colliery

• The BGS mine-plans catalogue holds a Mining Remediation Authority abandonment plan titled 'Limeylands' (catalogue 9539, Parrot, dated 1928); the catalogue gives no location and the plan's details do not clearly tie it to this working, so it may belong to another of the same name. (uncertain)

Oxenford Colliery

• Oxenford No. 3 was sunk in 1949 and closed in January 1959. (disputed)
• Oxenford closed in 1962, with Bellyford. (disputed)

Tynemount Colliery

• Historic Environment Scotland records sinking and production as commencing in 1924. The Fourth Statistical Account of East Lothian says the colliery was sunk in 1925. (disputed)
• Historic Environment Scotland gives the colliery as closed in 1952 and abandoned in 1962. The Fourth Statistical Account gives the closure as 1962, which is the abandonment date rather than the end of working. (disputed)
