Phoenix Tailings’ $375M rare earth plant: project economics for mine planners
Reviewed by Joe Ashwell

First reported on MINING.com
30 Second Briefing
Phoenix Tailings will build the $375 million Freedom Separation rare earths processing plant at Eastman Business Park in Rochester, New York, a 500,000-square-foot facility designed to process over 18,000 tonnes of mined and recycled feedstock annually and produce more than 4,400 tonnes per year of separated rare earth oxides by 2028. The plant is part of the $1.2 billion Freedom project separation and metallisation platform, backed by a $500 million conditional loan commitment from the US Department of War’s Office of Strategic Capital. New York State will provide $3 million in performance-based tax credits, with at least 90 new jobs expected on site and over 500 across three states.
Technical Brief
- Freedom Separation is sited within Eastman Business Park, leveraging existing heavy industrial, utilities and chemical-processing infrastructure.
- Phoenix Tailings is targeting commercial-scale processing of both mined concentrates and recycled rare earth-bearing materials.
- Production ramp is scheduled to begin in 2027, with staged commissioning implied before full throughput.
- The Rochester plant is one element of Phoenix Tailings’ wider $1.2 billion Freedom separation and metallisation platform.
- A $500 million conditional loan commitment from the US Department of War’s Office of Strategic Capital underpins project financing.
- New York State support is structured as $3 million in performance-based tax credits tied to delivery milestones and jobs.
- At least 90 on-site roles are planned at Eastman Business Park, within more than 500 jobs across NY, MA and NH.
- Federal and state political backing (Governor Hochul, Senator Schumer) reduces permitting and policy risk for midstream rare earth capacity.
Our Take
Phoenix Tailings appears repeatedly in our coverage alongside MP Materials and Energy Fuels as one of a small group of US‑backed rare earths players that have collectively secured multi‑billion‑dollar federal support, signalling that the Freedom Facility is being positioned as part of a coordinated domestic supply chain rather than a standalone niche plant.
The conditional $500 million loan from the US Department of Defense’s Office of Strategic Capital, referenced in a June 2026 item on the ‘Freedom Facility’, implies that the $375 million Rochester plant cost is being underpinned by defence‑grade offtake expectations, which typically come with tighter performance and schedule covenants than commercial bank debt.
Linkages in our database between Phoenix Tailings and Advanced Magnet Lab’s DLA‑funded NdFeB magnet work suggest that rare earth oxides from the Freedom Project are likely to be targeted at downstream defence and EV magnet producers, increasing pressure on China‑sourced material in those specific high‑specification segments.
