Apex Confirms Favourable Monazite and Bastnaesite Mineralogy at the Rift Rare Earth Project
Rhea-AI Summary
Apex Critical Metals (OTCQX:APXCF) reported quantitative X-ray diffraction results from drillholes at its 100%-controlled Rift Rare Earth Project in Nebraska, confirming monazite and bastnaesite as the dominant rare earth element (REE) host minerals in the Trinity and Neo zones. According to Apex, these minerals underpin most global rare earth oxide production and have well-established processing flowsheets, which the company views as reducing technical and metallurgical risk for Rift.
Apex has engaged SGS Geochemistry to conduct TIMA mineralogical analysis, with results to guide preliminary metallurgical testwork at SGS’s Lakefield facility. The company also renewed a three‑month marketing agreement with Rumble Strip Media for C$1,000,000 and a 12‑month Zimtu Capital marketing program at $15,000 per month, both focused on investor awareness.
Positive
- Monazite and bastnaesite confirmed as dominant REE hosts at Rift’s Trinity and Neo zones via QXRD analysis
- Use of well-established processing flowsheets for monazite and bastnaesite may reduce technical and metallurgical risk, according to Apex

- Additional 12‑month marketing support via Zimtu ADVANTAGE program at $15,000 per month for strategic investor engagement
Negative
- High near-term marketing cash outlay of C$1,000,000 over three months under the renewed Rumble Strip agreement
- Ongoing marketing commitment of $15,000 per month for 12 months to Zimtu Capital, adding fixed costs
- Project still in early-stage exploration with metallurgical work and an inaugural mineral resource estimate yet to be completed
News Explained
Rift’s processing derisking remains an early-stage assessment, while related-party marketer Zimtu has disclosed Apex share and warrant holdings.
Apex reports completed QXRD characterization of selected Rift drill-core rejects, but preliminary metallurgical testwork remains a future step following the planned TIMA analysis.
Because the company calls the finding a positive early indicator and says it will inform future testwork, its statement that the results “significantly derisk” Rift is an early-stage assessment rather than a reported recovery result.
The renewed Zimtu arrangement also carries a disclosed related-party governance detail: Zimtu owns 7,947,216 common shares and 278,336 warrants, and approval excluded the two directors who disclosed their Zimtu relationships and recused themselves.

Highlights:
Mineralogical analysis confirms monazite and bastnaesite as the dominant rare earth element (REE)-bearing minerals within the Trinity and Neo zones at the Rift Project
Monazite and bastnaesite have well-established mineral processing flowsheets for recovery from carbonatite-type deposits and, therefore, significantly derisk the Rift Project by providing a clear pathway and approach for testwork.
Monazite and bastnaesite are the dominant source minerals for REEs globally, both today and historically, and thus form the backbone of the rare earth raw materials industry.
Mineralogical data will inform preliminary metallurgical testwork anticipated to begin shortly at SGS Canada's Lakefield, ON, facility.
Sean Charland, CEO of Apex Critical Metals, commented: "These mineralogical results are an important confirmation for the Rift Project and validate the historical literature. Monazite and bastnaesite are the same two minerals that underpin the majority of the world's existing REE supply chain. Seeing them as the dominant REE hosts at Rift, rather than a complex assemblage of less-understood phases, is a strong signal for the potential metallurgical simplicity of this deposit as we advance toward our inaugural mineral resource estimate."

Key Observations and Takeaways
Mineralogical characterization was completed on representative drill core reject samples selected from drillholes RIFT26-001A, RIFT26-002, RIFT26-003 and RIFT26-005A by Quantified X-ray Diffraction (QXRD). The results demonstrate that REE mineralization at Rift is hosted predominantly within monazite and bastnaesite, the two REE minerals responsible for the substantial majority of global rare earth oxide production. Monazite and bastnaesite have well-documented processing flow sheets which reduce the technical risks when compared with other novel REE mineral species.
Global carbonatite-sourced REE supply is primarily derived from monazite and bastnaesite. Decades of industrial-scale operating history at deposits such as Mountain Pass and Bayan Obo have refined the processing routes for these two minerals, reducing the technical and metallurgical risks typically associated with other, less-established REE mineral phases.
Building on the QXRD results reported herein, the Company has engaged SGS Geochemistry to complete TIMA (TESCAN Integrated Mineral Analyzer) analysis on select samples from the Trinity and Neo Zones. TIMA is an automated mineralogical technique to characterize individual mineral grains, providing quantitative data on REE mineral species, grain size distribution, and degree of liberation from host gangue minerals. Results from the TIMA program are expected to refine understanding of REE mineral speciation. This information is intended to inform the design of preliminary metallurgical testwork at the Rift Project which will be undertaken by SGS Geochemistry following TIMA results.
The Company considers the identification of a simple, two-mineral-dominant REE assemblage to be a positive early indicator for potential downstream processing, as both monazite and bastnaesite are well understood industrially and are amenable to conventional beneficiation techniques (gravity/magnetic/flotation concentration).
Marketing Update
The Company also announces that it has renewed its marketing and investor awareness agreement with Rumble Strip Media Inc. ("Rumble") to support the Company's ongoing investor outreach initiatives (the "Rumble Agreement").
Under the Rumble Agreement, Rumble will provide digital marketing, content creation, advertising development, media planning and buying, and related consulting services to Apex. In consideration, Apex will pay an aggregate of C

Quality Assurance / Quality Control
Samples selected for QXRD analysis were derived from pulverized reject material generated during standard geochemical sample preparation and were representative of samples previously reported for whole-rock REE geochemistry. Mineralogical analysis was completed by Activation Laboratories Ltd. using powder X-ray diffraction with quantitative phase abundance determined by Rietveld refinement.
