Similar Deposits To Mountain PassTony Mariano: We know of a number of deposits in North America where we can acquire the light lanthanides. We can do well going from lanthanum into the mid-atomic number lanthanides. That would include deposits such as Molycorp Mineral's (NYSE:MCP) Mountain Pass in California,
Rare Element Resources Ltd.'s (TSX.V: RES) Bear Lodge carbonatite in Wyoming, and Wicheeda Lake in British Columbia, which is run by a private company, Spectrum Mining Corporation. [Editor's note: Molycorp Minerals (NYSE:MCP) went public 7/29/2010. See
press release.]
The Mountain Pass deposit is rich in LREEs with ample grade and tonnage, and Molycorp has the technology to produce excellent REE concentrates for lanthanum, cerium, praseodymium, neodymium and samarium. And based on work that I have done in Wicheeda Lake, that mineralogy is amenable to physical concentration and there should be no problems in chemical processing.
Although we have sources in North America for LREEs in addition to those I just mentioned, to me they may have the best potential.
Anthony N. (Tony) Mariano, PhD, is a geological consultant on rare earths and other rare metals. For decades, he has been the "go-to" expert on the geology and mineralogy on rare earths, niobium-tantalum and other rare metals. A seasoned mineralogist and petrographer, Tony integrates his strong knowledge of geology and extractive metallurgy ("geometallurgy") to predict success or failure of proposed rare earth ventures. Companies around the world depend on his professional opinions on the potential economic viability of deposits based on mineralogical examination, lab work and field visits. After earning his PhD in geology from Boston University, Tony worked a number of years at Kennecott Research's lab in Massachusetts, after which he began his career as a consulting geologist, specializing in carbonatite-hosted rare earth and niobium deposits.
