Haggruvan was more or less an auxilary mine to Ställbergsgruvan ( https://pbase.com/jakobe/stallberg ), as the mines were connected via a drift at 500 meters depth. All ore was brought up at Klingspor's shaft in Ställberg. However, the previous wooden headframe was replaced in 1955 with a modern concrete one. Haggruvan was closed in 1968, whereas Ställbergsgruvan continued its operations until 1977.
