Harry Crofts (Shireoaks No3 or Anston colliery) was ill fated from the start by poor geology. It was sunk 1924/26 to Top Hard at 488 yards (446m) and production began in Aug 1928 but stopped in 10th Aug 1929, however the single shaft was used until 1931. The shaft was re-opened and used for ventilation for Shireoaks again in 1951, and shared the shaft with Kiveton Park 1957-1970 but was capped off temporarily due to water ingress in 1970s and finally capped in May 2002.
