people are speculating about fed interest in pebble due to Rhenium deposits there
"The
Pebble deposit in Alaska holds a particularly large store of
rhenium on U.S. soil. ... Calculations completed in 2011 estimates the measured and indicated resource contains roughly 0.45 g/t
rhenium, which equates to around 2.9 million kilograms, or roughly US$6.4 billion, of the critical superalloy metal."
Rhenium - Wikipedia
"
Nickel-based
superalloys of rhenium are used in the combustion chambers, turbine blades, and exhaust nozzles of
jet engines. These alloys contain up to 6% rhenium, making jet engine construction the largest single use for the element. The second-most important use is as a
catalyst: rhenium is an excellent catalyst for
hydrogenation and isomerization, and is used for example in
catalytic reforming of naphtha for use in gasoline (rheniforming process). Because of the low availability relative to demand, rhenium is expensive, with price reaching an all-time high in 2008/2009 of US$10,600 per
kilogram (US$4,800 per pound). Due to increases in rhenium recycling and a drop in demand for rhenium in catalysts, the price of rhenium has dropped to US$2,844 per
kilogram (US$1,290 per pound) as of July 2018"
