Potentate Mining and Rock Creek Sapphires in the media.
This week Potentate Mining is in the spotlight on pages 12-13 of the latest edition of Gems & Jewellery, a publication of the Gemmological Association of Great Britain (GemA) – the oldest Gemmological Association in the world.
Recently, Montana-based Potentate Mining LLC secured approximately 3,000 acres of sapphire-bearing ground covering the famous Rock Creek sapphire district, including the Gem Mountain sapphire mine, near Philipsburg, Montana. Since the discovery of these sapphire deposits in the 1890s, this is the first time that one company has consolidated such a large land position, encompassing the old alluvial sites as well as the area on the hills in between these old workings (figure 1). Potentate has assembled a team of highly experienced placer miners, geologists, mining engineers, and heavy equipment operators to recover and process the sapphires from this mine.
Potentate Mining and our Rock Creek Sapphires are on centre stage in the latest edition of InColor, a publication of the International Colored Gemstone Association (ICA) representing an international membership of colored gemstone and jewelry dealers, wholesalers, miners, and gemmological laboratories around the world. The Director of Marketing – WFB is currently on the Board of Directors of the ICA.
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.
