Northern Dynasty on Thursday its US subsidiary聽Pebble聽Limited Partnership has filed an appeal with the US Army Corps of Engineers (USACE) over its decision to deny a key water permit for the Pebble copper-gold-molybdenum-silver-rhenium聽mine in Alaska.
The USACE denied the Clean Water Act permit in November because the plan submitted by the聽Pebble聽Limited Partnership detailing how it would handle the project鈥檚 waste in the ecologically sensitive area did not comply with guidelines.
鈥淎dditional details about the聽Pebble聽Partnership鈥檚 RFA (request for appeal) submission will be released in the days and weeks ahead,鈥� Northern Dynasty Minerals said on Thursday.
Former President Donald Trump had moved closer in July to approving the mine鈥檚 permit, reversing a decision by Barack Obama.
But a prominent group of Republicans, including Trump鈥檚 son Donald Trump Jr., had publicly voiced opposition, saying the mine could destroy fishing and hunting areas.
鈥淣orthern Dynasty believes that key aspects of the USACE鈥檚 ROD and permitting decision 鈥� including its 鈥榮ignificant degradation鈥� finding, its 鈥榩ublic interest review鈥� findings and its perfunctory rejection of Pebble鈥檚
CMP 鈥� are contrary to law, unprecedented in Alaska and fundamentally unsupported by the administrative record,鈥� the company said in a press release.
With resource estimates including 6.5 billion tonnes in the measured and indicated categories containing 57 billion pounds of copper and 71 million ounces of gold, 3.4 billion pounds of molybdenum and 345 million silver ounces, if permitted, Pebble would be North America鈥檚 largest mine.
Midday Friday, Northern Dynasty鈥檚 shares were up 4% on the TSE. The company has a C$344 million market capitalization.
