Onfolio Eyes $3B Helium Resource with 20 Bcf Arizona Assets
ONFO•Onfolio signed an LOI with Paramount Helium to acquire Proton Green’s debt, securing over 20 billion cubic feet of helium and carbon dioxide assets in Arizona’s St. Johns Unit. Independent analysis estimates the site holds more than 50 kg of helium-3 valued at $10–20 million per kilogram.
1. Strategic LOI with Paramount Helium
Onfolio has executed a binding letter of intent with Paramount Helium to acquire the senior debt position of Proton Green, granting Onfolio control of helium and carbon dioxide assets in the St. Johns Unit, northeastern Arizona. This transaction paves the way for Onfolio’s entry into the global $122 billion industrial gas market.
2. St. Johns Unit Resource Overview
The St. Johns Unit resource is estimated to contain over 20 billion cubic feet of recoverable helium—approximately ten times the size of the former U.S. Federal Helium Reserve—and substantial carbon dioxide reserves. Independent evaluations identify more than 50 kg of helium-3, a rare isotope with applications in quantum computing and neutron detection, valued at $10–20 million per kilogram.
3. Market Implications and Outlook
Onfolio’s acquisition targets strategic independence in critical gas supply chains for semiconductor manufacturing, aerospace, defense and emerging technologies. The company plans to advance due diligence, finalize the binding combination, and develop the St. Johns assets to generate cash flow and establish a leading North American helium position.
