IAEA Reports Construction Activity at Iran’s Pickaxe Mountain Site
Satellite imagery shows increased excavation and road work at the underground site, while the IAEA says it still cannot verify activity inside.
- On Thursday, IAEA Director-General Rafael Mariano Grossi reported construction activity at Iran's Pickaxe Mountain facility near Natanz, monitoring developments remotely through satellite imagery.
- A CSIS analysis of six years of imagery indicates the site has moved from large-scale excavation toward internal construction and external reinforcement to protect sensitive nuclear infrastructure from military attacks.
- Iran restricted IAEA access following damage during a 12-day conflict in June 2025, preventing the agency from independently verifying the current condition of Iran's stockpile of uranium enriched to near weapons-grade levels.
- President Donald Trump threatened strikes against the site on Friday, warning Tehran against further activity as the United States military develops a new bunker-buster munition for deeply buried facilities.
- The United States awarded a prototype contract for a new munition succeeding the GBU-57A Massive Ordnance Penetrator in September 2025, though analysts note the site remains incapable of enrichment work.
