Recent satellite imagery has shown that Iran is reportedly fortifying an underground complex at Mount Kolang Gaz La, also known as Pickaxe Mountain, which is situated near its nuclear facilities. This construction comes at a critical time with heightened US-Iran tensions, particularly as discussions continue around Iran's nuclear program and its implications for international security.
The Institute for Science and International Security (ISIS), a US-based think tank, analyzed the images and indicated that new tunnel entrances are being reinforced, potentially aimed at protecting uranium enrichment activities or critical equipment. Despite Iran's repeated claims of a peaceful nuclear agenda, experts express concerns that the site could be operational soon.
Previous comments by former US President Donald Trump highlighted fears that Iran was close to developing nuclear weapons, with a warning issued in June 2025 about the nation's nuclear advancements. The site at Pickaxe Mountain had notably remained untouched during the US and Israeli airstrikes that year, drawing attention to its strategic significance.
The recent images reveal fresh concrete being applied over one of the tunnel entrances. Additionally, other entrances at the Isfahan nuclear site and Natanz facility have undergone sealing and repair work, with the suggestion that Iran is preparing defenses against potential air strikes.
Experts note that the presence of heavy construction machinery suggests that operations at Pickaxe Mountain may not yet be ready but indicate ongoing developments that could escalate tensions further if not managed through diplomatic channels. The call for renewed negotiations highlights the international community's concern over Iran's nuclear program amidst fears of an arms race in the region.
