Granby Consolidated Mining, Smelting and Power Co. was established by charter to operate in the Boundary region of southern British Columbia.

In 1891, Henry White and Matthew Hotter staked the Knob Hill and Old Ironsides claims respectively on what became known as Phoenix Mountain.

Miner, president of the Quebec-based Granby Rubber Company and a director of the Eastern Townships Bank.

In 1899, Graves and Miner formed the Granby Consolidated Mining & Smelting Co.,[3] which bought the Fourth of July, Victoria, Aetna, and Phoenix claims.

That July, the first trainload descended to the Granby smelter at Grand Forks,[3] which commenced processing in August.

Augmented by rate cutting, GN quickly replaced CP in hauling most of the mountain's ore.[3] The blister copper produced by the smelter[11] went to the Nichols Chemical Company in Brooklyn, New York for further refining.

Graves in liaison with GN's James J. Hill sought control,[3] but William H. Nichols acquired a majority interest in 1904.

[7] By 1906, the Knob Hill and the Old Ironsides workings joined underground to become a huge single network called the Granby mine, which spread into the Victoria claim that year.

By 1908, Granby Consolidated owned 35 claims on the mountain,[3] and smelter processing peaked at 1,178,853 tons, including ore from more distant mines.
