Tactical Resources’ Nasdaq move and Texas REE tailings: key points for mine planners
Reviewed by Joe Ashwell

30 Second Briefing
Tactical Resources is pursuing a Nasdaq listing via a SPAC merger with Plum Acquisition Corp. III as it advances the Peak rare earths project in West Texas, built around ~4 million tonnes of REE-bearing tailings at the Sierra Blanca quarry. The company has now acquired the underlying quarry, including land, mineral rights, existing power, water, rail and crushing infrastructure, enabling a feedstock-first strategy with no new mining or primary permits. Development centres on a pilot and then modular demonstration plant for direct-leach extraction and separation of heavy rare earths such as dysprosium, terbium and yttrium.
Technical Brief
- Tactical now owns the quarry land, mineral rights, equipment and stockpiled material outright (100% control).
- Stockpiles generated over more than 20 years of railway ballast production are interpreted as REE-enriched.
- Approximately four million tonnes of tailings are expected to underpin at least five years of initial throughput.
- Direct-leach amenability of the hard-rock material allows bypassing several conventional rare earth beneficiation stages.
- Development sequence runs pilot plant → on-site demonstration plant → modular scale-up, aligned with staged offtake contracting.
- Heavy REE focus (Dy, Tb, Y) targets magnet and defence supply chains prioritised in recent US policy support.
Our Take
Rare earths pieces in our database that involve existing stockpiled material, like the 4 million tonnes of REE-bearing tailings at the Sierra Blanca quarry, typically move faster through early permitting because they are framed as waste reprocessing rather than greenfield mining.
Texas-linked rare earths and critical minerals items in our coverage often sit alongside national security narratives, so a Nasdaq listing for Tactical Resources would likely help position The Peak project as a US-aligned alternative to Congo- and China-exposed supply chains for dysprosium, terbium and yttrium.
With tailings alone expected to support about five years of operations, Tactical Resources can refine its flowsheet and offtake strategy before committing to full-scale primary mining, a sequencing approach that has reduced ramp-up risk at other US critical minerals projects in our database.
