Zentek lines-up US patent for EMI shielding technology
Zentek (ZEN) filed a U.S. patent for its EMI shielding coating, ZEN-EMI-01, made from graphite from its Albany deposit. The coating showed promise in early lab tests, reducing EMI from radar and satellite frequencies. Albany's PEA estimates 34,500 tonnes of annual graphite production, with a post-tax NPV of $3.85 billion. The company cautions that commercialization is not assured.
