Mallorn Bio's proprietary phytomining system grows biomass on low-value and contaminated land. The plants absorb residual gold. We recover the gold and certify the land is rehabilitated.
Our gold has been independently certified as the lowest-impact gold ever produced.
The value of gold in artisanal and small-scale mining (ASGM) tailings is between $220 billion and $300 billion. Other uneconomic gold resources total ~$7 trillion.
15 million artisanal miners work on contaminated sites with no viable clean-up technology at scale. Industry all-in sustaining cost has risen to $1,500+/oz as ore grades decline globally — and the average development lead time for a new gold mine is more than 15 years.
No scalable, low-cost technology exists to simultaneously remediate land and recover residual gold.
AISC ~$800/oz versus $4,700/oz gold price.*
No heavy machinery. No drill & blast. The most capital-efficient gold recovery method ever demonstrated.
Average climate impact across all three trial locations: 4,869 kg CO₂e per kg of gold doré — against a global average of 47,835. Between 5× and 42× less impact.*
Behind the field system sits a proprietary AI platform that assesses satellite data, historical industry datasets and artisanal-mining databases to identify target land — combined with more than 90 geologists on the ground managing site sampling, acquisition, and landholder and government relations.
