San Francisco Startup Claims Breakthrough in Transforming Mercury Into Gold
San Francisco startup Marathon Fusion claims to produce stable gold from mercury using nuclear fusion technology at a rate ten times higher than CERN records, opening potential avenues for commercial energy and rare medical isotopes.
A San Francisco-based startup claims it has achieved what alchemists pursued for centuries: transforming base metals into gold using advanced nuclear technology rather than chemical tricks. Marathon Fusion announced on October 21 that an experiment conducted last month successfully produced stable gold at a rate ten times higher than the record previously measured at the CERN particle accelerator.
The scientific process involves bombarding mercury atoms with high-energy neutrons derived from nuclear fusion reactions, altering the atomic nucleus to create an unstable isotope that subsequently decays into genuine gold. According to the company, the resulting substance possesses identical properties to naturally mined precious metal.
While this is not the first instance of artificial gold creation—as CERN researchers reported generating microscopic amounts of gold from lead back in 2025—Marathon Fusion reports a significant scale-up. However, the company has yet to disclose the exact quantity produced, the total cost of the experiment, or whether independent verification has been achieved.
Market experts note that commercial viability remains distant. Company calculations suggest a future one-gigawatt commercial fusion reactor could theoretically yield about two tons of gold annually as an energy generation byproduct, potentially boosting a power plant's revenue from 223 million dollars to 482 million dollars per year. Yet, with global annual gold mining reaching thousands of tons, a single facility would not radically disrupt the global market.
Beyond precious metals, Marathon Fusion's primary strategic focus includes the production of rare radioactive isotopes utilized in targeted cancer therapies. The company hopes its developing technology will eventually address severe medical shortages and supply critical diagnostic and therapeutic materials to the healthcare sector.
