New intelligence shared between Israel and the United States is raising fresh concerns that Iran may be quietly rebuilding key parts of its nuclear program beneath one of the most heavily fortified underground facilities in the Middle East.

According to multiple reports, Israeli intelligence believes Iran transferred thousands of uranium-enrichment centrifuges into the deeply buried tunnel complex known as Pickaxe Mountain, located near the Natanz nuclear facility, following the 12-day Israel-Iran conflict in June 2025.

If accurate, the assessment suggests Tehran could be positioning itself to resume uranium enrichment in a location that is significantly more difficult to target than its previously known nuclear facilities.

The intelligence has renewed international debate over Iran’s nuclear ambitions, future military action, and the effectiveness of existing international monitoring efforts.

Israeli Intelligence Raises Alarm

According to reporting by The Wall Street Journal, Israeli intelligence officials believe Iran relocated thousands of nuclear centrifuges into the underground Pickaxe Mountain complex after Israeli and U.S. airstrikes targeted Iran’s primary nuclear facilities during last year’s conflict.

Israeli officials reportedly shared the assessment with the United States, warning that Iran may now possess the capability to restart enrichment activities inside one of the most hardened nuclear facilities ever constructed.

The reported intelligence has not been independently verified, and Iran has not publicly acknowledged transferring centrifuges to the site.

An Israeli military official familiar with last year’s campaign reportedly stated that the earlier strikes did not sufficiently eliminate all elements of Iran’s nuclear weapons infrastructure and suggested additional military action may still be required.

Why Pickaxe Mountain Matters

Known inside Iran as Mount Kolang Gaz La, Pickaxe Mountain has attracted the attention of Western intelligence agencies for years.

The underground complex lies approximately one mile south of Iran’s Natanz enrichment facility and is believed to extend between 295 and 450 feet beneath solid rock, making it one of the most heavily protected nuclear sites in the country.

Analysts believe the facility was originally intended to replace Iran’s centrifuge assembly plant that suffered major damage during a 2020 explosion widely attributed to sabotage.

Because of its extraordinary depth, military experts believe destroying the facility would present a major challenge even for advanced bunker-busting weapons.

Satellite imagery has reportedly shown continued tunnel construction, reinforced entrances, expanded security, and ongoing truck traffic over the past year.

Could Iran Secretly Enrich Uranium?

According to Israeli intelligence, the relocated centrifuges could potentially be used to enrich Iran’s existing stockpile of uranium already enriched to approximately 60% purity.

While 60% enriched uranium is not considered weapons-grade, experts note that it is technically much closer to weapons-grade enrichment than lower enrichment levels used for civilian nuclear power.

David Albright, president of the Institute for Science and International Security, told The Wall Street Journal that it is likely Iran has moved centrifuges into the underground tunnels.

Former National Security Council official Nate Swanson warned that the greatest concern would be a clandestine breakout—a scenario in which Iran secretly enriches uranium beyond international oversight.

He emphasized that without inspections, the international community cannot verify what activities are taking place inside the underground complex.

IAEA Still Lacks Access

One of the greatest concerns surrounding Pickaxe Mountain is the continued lack of access by the International Atomic Energy Agency (IAEA).

According to reports, Iran has denied inspectors access to the facility and has not fully disclosed its intended activities there.

IAEA Director General Rafael Grossi previously stated that Iran informed the agency several years ago of its intention to conduct nuclear-related activities at the location.

Without inspections, independent verification remains impossible.

Iran continues to insist its nuclear program is exclusively peaceful and has repeatedly denied seeking nuclear weapons.

Trump Warns Pickaxe Mountain Could Become a Target

President Donald Trump recently identified Pickaxe Mountain publicly as a possible future military target.

Speaking during an interview with conservative radio host Hugh Hewitt, Trump stated:

“Pickaxe is a possible target for a nice, big, fat shot right near the front door.”

The remarks marked one of Trump’s clearest public references to the underground facility.

Israeli Prime Minister Benjamin Netanyahu has reportedly continued encouraging Washington to maintain pressure on Tehran and prevent Iran from rebuilding its nuclear infrastructure.

Whether additional military operations occur remains uncertain.

Growing Regional Tensions

The reported intelligence arrives as tensions across the Middle East remain elevated following last year’s conflict.

Israel has consistently warned that preventing a nuclear-armed Iran remains one of its highest national security priorities.

Meanwhile, American officials continue balancing military deterrence with diplomatic efforts designed to prevent further escalation throughout the region.

If the intelligence proves accurate, Pickaxe Mountain could become one of the most strategically important nuclear sites in the world.

Prophetic Perspective

The continuing focus on Iran’s nuclear ambitions comes as many students of Bible prophecy closely watch developments involving Israel and the nations surrounding it. Scripture repeatedly identifies the Middle East as a region that will play a central role in end-times events (Zechariah 12; Ezekiel 38–39; Matthew 24). While the Bible does not specifically identify modern nuclear technology, it warns of increasing wars, rumors of wars, and escalating international tensions before Christ’s return. Believers are encouraged to remain discerning, avoid speculation beyond what Scripture reveals, and place their confidence not in political leaders or military power but in God’s sovereign plan.

Conclusion

Israeli intelligence believes Iran may be quietly rebuilding critical portions of its nuclear infrastructure deep beneath Pickaxe Mountain, a facility that could prove extraordinarily difficult to destroy if conflict resumes. Although these assessments have not been independently verified, they have intensified concerns within Israel, the United States, and among international nuclear experts regarding Iran’s future intentions. As calls grow for renewed IAEA inspections and diplomatic pressure, the world will be watching closely to determine whether Pickaxe Mountain becomes the next focal point in the long-running confrontation over Iran’s nuclear program.
