Critical Minerals Alaska - Rhenium superalloy metal used in jet turbines

Pebble Limited Partnership

The measured and indicated resources at the Pebble deposit in Southwest Alaska continues roughly 2.9 million kilograms of rhenium, or roughly US$6.4 billion of the critical metal.

With a melting point of 5,756 degrees Fahrenheit and a heat-stable crystalline structure, rhenium is extremely resistant to both heat and wear. This durability makes it a vital element in superalloys used in jet and industrial gas turbine engines.

"The high-temperature properties of rhenium allow turbine engines to be designed with finer tolerances and operate at temperatures higher than those...
