"The following investigation was undertaken to determine the adaptibility [sic] to amalgamation and cyanidation of a certain ore from the property of Mr. Charles Bush near Custer, South Dakota. A preliminary sample of the ore was obtained and laboratory tests made upon it. A ton lot of the ore was then put through the ore dressing laboratory at the South Dakota School of Mines. Upon examination the large sample was found to differ in value and to some extent in character from the preliminary sample, but the scheme of treatment worked out for the first sample was found to work excellently on the main sample"--Page 1.
