President Donald Trump has threatened to launch a military strike against Pickaxe Mountain, a heavily fortified underground facility near Iran’s Natanz nuclear complex that Western analysts believe could play a significant role in Tehran’s future nuclear ambitions.
The comments come as the U.S. military has carried out 11 consecutive nights of strikes against Iranian military targets, marking one of the most sustained campaigns against Iran in recent history. If a strike on Pickaxe Mountain occurs, analysts warn it would represent another major escalation in the conflict and could trigger retaliation across the region.
Why Pickaxe Mountain Is Drawing Global Attention
Pickaxe Mountain, known in Iran as Kuh-e Kolang Gaz La, sits just south of the Natanz uranium enrichment facility.
Construction began in 2020 after an explosion destroyed Iran’s above-ground centrifuge assembly plant at Natanz. Iranian officials said the new underground complex would replace that facility with a far more secure installation.
Security experts believe the site was intentionally built deep beneath solid rock to withstand conventional airstrikes.
According to the Institute for Science and International Security (ISIS), the underground complex is estimated to sit roughly 100 meters beneath the mountain, making it one of Iran’s most protected nuclear-related facilities.
Satellite imagery reviewed by multiple research organizations also shows extensive tunnel construction, reinforced security walls, and multiple underground entrances.
Trump Signals Strike Could Be Imminent
Speaking from the White House, Trump suggested military action may be only days away.
“We’ll be hitting that area very probably pretty soon… and very heavily.”
The president made similar comments earlier this month, saying the administration has been closely monitoring activity at the site.
His remarks suggest U.S. intelligence may believe the facility has become increasingly important to Iran’s nuclear program.
Why Analysts Believe the Site Matters
While Iran insists Pickaxe Mountain is not currently conducting nuclear activity, many Western nuclear experts believe the facility could eventually house highly sensitive operations.
David Albright, founder of the Institute for Science and International Security, said the mountain appears large enough to accommodate:
- Uranium centrifuge enrichment facilities
- Advanced centrifuge assembly operations
- Potential nuclear weapons research activities
However, analysts caution that there is no public evidence confirming exactly what is currently operating inside the facility.
Following the destruction of several Iranian nuclear sites during U.S. strikes in 2025, satellite imagery indicates construction at Pickaxe Mountain has accelerated.
Researchers at the Center for Strategic and International Studies (CSIS) report that Iran has expanded tunnel networks while adding extensive perimeter defenses around the complex.
Iran Warns of Major Retaliation
Iran responded forcefully to Trump’s latest comments.
Military officials warned that any attack on Pickaxe Mountain would represent what they described as “an explosion of war in the region.”
Iran’s Khatam Al-Anbiya military command warned that U.S. interests, along with those of American allies, could become targets if such an attack occurs.
Meanwhile, Iran’s Foreign Ministry dismissed U.S. claims about the site, arguing that Washington is using false allegations as justification for further military action.
Why Investors Should Pay Attention
Although Pickaxe Mountain itself has little direct economic significance, any attack on the facility could have broad market implications.
Investors will likely be watching for impacts on:
- Oil prices, particularly if tensions threaten shipping through the Strait of Hormuz.
- Defense stocks, which have generally outperformed during periods of heightened geopolitical risk.
- Energy and transportation companies exposed to Middle East supply disruptions.
- Safe-haven assets such as gold and U.S. Treasuries if military tensions intensify further.
With military operations already expanding and rhetoric escalating on both sides, markets remain highly sensitive to developments involving Iran’s nuclear infrastructure.
The Bottom Line
Pickaxe Mountain has become one of the most closely watched locations in Iran’s nuclear program because of its depth, security, and strategic location near Natanz.
Whether the site currently houses active nuclear operations remains unclear, but President Trump’s threat to strike it has elevated the mountain from a largely obscure facility to a potential flashpoint in an already volatile regional conflict.
For investors, any military action targeting the site would likely be less important than the broader consequences: the potential for wider regional escalation, higher energy prices, and increased geopolitical volatility across global financial markets.
