Enormous copper-gold deposit in Alaska contains enough of this superalloy metal to supply global demand for 40 years North of 60 Mining News – November 2, 2018
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 of...
