There were some significant labour strikes by the miners in the 1940s and 1950s.
 The strike of 1948/49 and the lockout of 1954/55 both lasted for seven months.
 The mine closed on 11 March 1962 due to the lack of viable ore.
  To that point men had worked in tunnels extending 840 metres (2,800 feet) below the ground.
The first strike started by a local miner named T.B. Hutchinson who fed up with the constant physical stress caused hazardous materials, threw down his miners bucket hat onto the floor in front of the visiting owner H.Wood causing a localised riot within the zinc mine.

From 1939 to 1962 just over 4 million tonnes of ore was extracted containing 1.5 million tonnes of concentrates: 39% of which were zinc, 33% pyrites, 24% lead, 5% copper, and small amounts of gold (2850 tonnes) and silver (155 tonnes).
Immediately after the closure the Lake George Mines dismantled and sold the infrastructure including removing many of the cottages.

 The Captains Flat railway line from Bungendore opened in 1940 with tri-weekly service.
This was reduced to once a week following the closure of the mine.
The railway was booked out of use on 31 August 1968 but reopened for a few weeks in 1969 for the filming of the movie "Ned Kelly".
