Marquette & Arizona Mining Company started in December 1902. In 1903 the main shaft was sunk to a depth of 562ft. Water was struck at 450ft. but, sinking continued until it was necessary to install a pump. At this time it was decided that it would be more economical to continue prospecting with a diamond drill. The shaft was allowed to flood to the 430ft. level. Work underground ceased in January 1904 and diamond drilling was stopped later that year. The surface facilities were substantial, with a headframe, hoist house, a boarding house, four bunk houses, a superintendent’s house and a few other dwellings.
