By Barbara Wheat Lipatapantop, Dec 2014 – Potentate Mining is proud to be the focus of a tremendous article written by industry expert Barbara Wheat Lipatapanlop in her recent article “Mining Sapphires In Montana” for TNJ Colors magazine.
Historic records found in the Montana Historical Society Archives show that production of sapphires from Rock Creek exceeds that of all other Montana sapphire districts combined (Berg, 2014). Sites include both alluvial and colluvial deposits, although the distinction between the two types of deposits can be somewhat arbitrary.
