Announcements, explained

Each one in plain English, with the numbers worked through for a shareholder.

17 Apr 2024regulatory community update▼ BadMajor

The Army Corps refused to engage with the remand at all, citing the EPA veto. The appeal win of April 2023 is worth nothing: the permit application will not be reconsidered while the veto stands.

Kopernik's principal and chief financial officer, Isabel Satra, joined the board eight months earlier.

The appeal worked: the Army Corps' Pacific Ocean Division refused to uphold the November 2020 permit denial, accepting that the process leading to the record of decision was not properly followed, and sent the application back to the Alaska District. Twenty-nine months after the denial, the company won the administrative fight - three months after the EPA veto made the permit moot.

The EPA issued its Final Determination on 31 January 2023, using its Clean Water Act veto to bar disposal of mine waste in the Bristol Bay watershed. Nine years after the 2014 proposed determination, and after a favourable impact statement in 2020, the deposit is put out of reach by the agency rather than by the permitting process.
