Of all the mines that had sunk shafts into the great Baltic Lode, the Trimountain could be considered the ugly ducking of the bunch. Besieged by mismanagement and difficult geography the mine was never able to fully take advantage of the copper bounty below its feet. From its establishment in 1899 up until its closure in 1920 the mine was only able to produce minimal profits – only about 3.5 million when all was said and done. (It’s neighbor to the south – the Champion – made over 25 million during the same period) Even after Copper Range took over operations in 1925, it could only keep the struggling mine afloat for another five years. It closed for good in 1930.
