Northern Dynasty Minerals Plunges 35.58% Amid Insider Selling, Legal Battle

On July 18, 2025, Northern Dynasty Minerals experienced a significant drop of 35.58% in pre-market trading, marking a substantial decline in its stock value.

The recent plunge in Northern Dynasty Minerals' stock price can be attributed to several factors, including insider selling and regulatory uncertainties surrounding its Alaska Pebble Project. The company's shares have seen a dramatic decrease, with reports indicating a drop of up to 55% in a single day due to insider selling activities. This selling spree involved three company directors who collectively sold 353,000 shares earlier this week, raising concerns among investors about the company's future prospects.

In response to the regulatory challenges, Northern Dynasty Minerals has taken legal action by filing a motion in Federal District Court in Alaska. The company is seeking a summary judgment briefing schedule to address the unlawfulness of the Biden veto on the Pebble Project. This move is aimed at expediting the legal process and potentially removing the veto, which has been a significant obstacle for the project's development. The company's CEO, Ron Thiessen, expressed confidence that the court will agree with their assessment that the veto was unlawful and emphasized the importance of the Pebble Project for the U.S. to achieve self-sufficiency in critical metals like copper.

Despite the challenges, Northern Dynasty Minerals remains committed to working with relevant government agencies to resolve the issue. The company's principal asset, the Pebble deposit in Southwest Alaska, holds significant potential for copper and other metals, making it a crucial project for the U.S. economy. The outcome of the legal proceedings and the company's efforts to secure the necessary permits will be critical in determining the future of the Pebble Project and the company's stock performance.
