Northern Dynasty Shares Plunge 55% on Insider Selling Activity

Insider Sales Trigger Sharp Decline in Northern Dynasty Shares

Northern Dynasty Minerals (TSX: NDM, NYSE-A: NAK) suffered a staggering 55% drop in share value on Thursday, marking its steepest single-day loss since 2020. The sell-off came after senior company insiders—including VP of engineering Stephen Hodgson and chairman Robert Dickinson—offloaded substantial holdings. The Toronto-listed stock fell to C$1.41 before partially recovering to C$2.27, with trading temporarily halted due to the volatility.

The company’s U.S.-listed shares mirrored this trend, plunging over 55% during morning hours before rebounding slightly. At the market’s close, Northern Dynasty’s market cap sat at roughly C$1.2 billion (US$870 million), signaling investor unease. The company has not issued a public statement in response to the trading activity or MINING.com’s inquiry.

Focus Keyphrase: Northern Dynasty Shares Plunge

Thursday’s collapse follows a brief rally earlier in July when Northern Dynasty announced potential litigation settlements with the U.S. Environmental Protection Agency. The company stated the move could aid in securing regulatory approval for its controversial Pebble project in Alaska. However, the optimism faded rapidly as insider selling fueled speculation over internal confidence.

The Pebble project, often cited as the largest undeveloped copper and gold resource globally, includes notable quantities of molybdenum, silver, and rhenium. Despite its mineral potential, the project remains polarizing. Located near Bristol Bay—home to the world’s largest sockeye salmon fishery—the mine has drawn fierce opposition from environmentalists, local communities, and regulators for over a decade.

Meanwhile, investors are closely watching political developments. The stock had shown renewed strength this year amid expectations that a Trump administration could relax regulatory pressures. Thursday’s plunge has now erased those gains, leaving investors uncertain about the project’s trajectory.

SuperMetalPrice Commentary:

The 55% nosedive in Northern Dynasty shares underscores the precarious balance between insider confidence and market sentiment. While regulatory optimism surrounding the Pebble project had briefly lifted valuations, insider selling now casts doubt on internal expectations. Moving forward, investors should closely monitor not just policy shifts, but executive actions. As political winds change and environmental scrutiny intensifies, Northern Dynasty’s future will depend as much on its internal discipline as on external decisions.
