A temporary production stoppage by China's largest rare earth exporter makes the creation of an American rare earth stockpile more likely, according to a report by dealReporter that appeared in yesterday's FT. The stoppage was a "wake-up call" for the US Department of Defense because the rare earth elements are needed for a variety of defense applications, writes dealReporter, citing a congressional source. The article quotes congressional sources and three rare earth companies saying that "the creation of a US rare earth strategic reserve is more likely to get the go-ahead after (Inner Mongolia Baotou Steel Rare-Earth (SHA:600111)) halted production. Such a move would create another source of demand for the metals, likely aiding a rebirth of the US rare earths industry."

Minmetals is not finished acquiring companies to add to its stable of base metal mines, according to Bloomberg. The state-run Chinese miner, with operations in Australia and Laos, a month ago snapped up Anvil Mining for $1.3 billion, thus expanding its reach into Africa. Anvil’s key asset is the Kinsevere mine, located in the Democratic Republic of Congo. Bloomberg reports the firm is planning more takeovers because it needs to extend the life of its mines and boost valuations. Minmetals' stock is undervalued compared to other comparable raw materials producers and consummating more deals would help raise its valuation, says the story, quoting a manager at First Asset Investment Management Inc.:

A proposed uranium mine in Virginia is attracting its share of proponents and detractors.

On Thursday a day-long forum was held to weigh arguments on either side of whether the private company should be allowed to (mostly underground) mine the Coles Hills deposit.

It seems that Guatemala's poor will go to extreme lengths for the chance to find valuable precious metals. The Associated Press reports that hundreds of people regularly search for jewelry and scraps of metal among the trash that spills from a drainage tunnel into Guatemala City's main landfill: Every day, about 300 hike to the bottom of the ravine and wade into the water in search of rings and bracelets made of silver or gold. The water sifts and carries away the lighter garbage, leaving heavy metals on the stream bed.
