Blackpatch Flint Mines

• The scheduling text gives eight shafts investigated in 1922-1930; Wikipedia and Dyer give seven excavated. (disputed)
• Dyer suggests the mines were worked intermittently for perhaps 500 years, from the Neolithic to the Middle Bronze Age, with a new shaft every five years. (uncertain)

Cissbury Flint Mines

• Wikipedia gives the period of use as both around 300 years and around 900 years in different sections. (disputed)
