Rare earth elements include the 17 lanthanides (La through Lu on the periodic table), plus scandium and yttrium. They are actually not all that rare and often occur together. However, they tend not to be concentrated in easily exploitable ore deposits, and they are difficult to separate out from their ore bodies. The Moun- tain Pass reserve is considered the richest site worldwide discov- ered to date. Since its closing, China has produced over 95% of the world’s rare earth elements. Mined nearly continuously since 1952, Mountain Pass ceased operations in 2002 except for minor processing of stockpiled ore after a series of environmental problems and increasing competi- tion from China. Now, after a lengthy process to permit a 30 year expansion plan, the latest owner, Molycorp, Inc., broke ground in January 2011 for an extensively reworked extraction and process- ing site. Molycorp states they will be mining fresh ore at the site some time in 2011 and will be operating at full capacity by the end of 2012. Mining rare earth elements is inherently risky. Radioactive ores often occur along with the rare earth elements.

But age isn’t Weverything. This 1.6 million acre wonderland is the third largest national park unit in the lower 48 states, smaller only than Death Valley and Yellowstone. Superlatives abound: the world’s largest Joshua Tree forest, 600-foot tall singing sand dunes, rugged “sky island” mountain ranges covered with pinyon-juniper forest, nearly 700,000 acres of designated wilderness, and rocky, sandy soils cov- ered with purple, blue, red, and pink carpets of flowers in spring. The Preserve is also renowned for its exceptional wildlife viewing, being a sanctuary for iconic species such as the desert tortoise, des- ert bighorn sheep, golden eagle, kit fox, and mountain lion. Although the Preserve is not widely known, it has developed a dedicated following. In 2009, several grassroots efforts to pro- tect and promote the Preserve came together to create a friends group. This effort was led by a diverse group of civic leaders, con- servationists, businessmen and women, writers, artists, and land CRAIG DEUTSCHE owners within the Preserve. Their shared care, effort, and voice Along the Mojave Road - Mojave National Preserve materialized into the formation of the Mojave National Preserve Conservancy (MNPC). This groups’ stated mission is: • Preserve, protect, and promote the unique natural beauty, ecolog- ical integrity, and rich cultural history of Mojave National Preserve • Build a community dedicated to the enduring stewardship of Mo- In This Issue March 2011 jave National Preserve The Conservancy is a non-profit organization built on individ- Writing A New Chapter: Rare Earth Mining At Mountain Pass ........
