Molycorp made a bold move last year with a $35M investment in Boulder Wind Power. This investment sustains a wind turbine technology that is not dependent on dysprosium and is strategically complementary for Molycorp given that company's seeming lack of dysprosium among its deposits. I've seen other media reports that describe Boulder Wind's technology as "non-ferrous," which is curious given Molycorp's move toward neodymium-iron-boron (NdFeB) magnet combinations.
It's worth noting that Great Western Minerals Group has had a well-integrated business model for many years. Molycorp's model is large in scale and is notable for having something that has eluded Great Western for some time: profitability.
Full disclosure: No positions in any companies mentioned.
