 It was at this time that an attempt was made to obtain a stock exchange listing, but it failed due to a variety of factors, including the move of mining into areas in which royalties had to be paid e.g.to AMAX in the south west area, the general decrepitude of the mining machinery and not least the start of a general crushing of the pillars and collapse in the centrally worked out areas, which was at least partially stopped by wrapping pillars with conveyor belt and old haulage rope to stabilize them.The employees subsequently sold Copper Range to Metall Mining Corporation (shortly to rename itself Inmet Mining) in 1989.
