Integral Metals Reports Preliminary Geomicrobial Results from Burntwood Project, Highlights Biological Pathfinder Potential for REE Exploration
Preliminary Geomicrobial Results Uncovers Promising Microbial Signatures Linked to Rare Earth Potential
CALGARY, Alberta, April 30, 2025 (GLOBE NEWSWIRE) — Integral Metals Corp. (CSE: INTG | OTC: ITGLF | FSE: ZK9) (the “Company” or “Integral”) is pleased to announce preliminary results from its 2024 geomicrobial survey at the Burntwood Project in northern Manitoba, where early findings demonstrate promising microbial patterns that may serve as biological pathfinders for rare earth element (REE) mineralization associated with carbonatite intrusions.
The survey covered the northern extent of the Burntwood Syenite-Carbonatite Complex, a regional intrusive system considered prospective for REE and other critical metals. A total of 808 unique soil samples were collected and analyzed using 16S rRNA and metagenomic sequencing, with sampling focused on confirmed carbonatite intrusion zones, background areas, and a systematic grid across the broader project area. Initial analysis revealed a statistically significant depletion of Burkholderiales and an enrichment of Rhizobiales in microbial communities overlying known carbonatite systems. These shifts, identified through LEfSe (Linear Discriminant Analysis Effect Size), may reflect subtle environmental changes linked to REE-bearing mineralization. These results are preliminary and form part of a broader, ongoing research initiative conducted in partnership with Dr. Andrew Cameron and the Institute for Microbial Systems and Society (IMSS) at the University of Regina. The project is supported by funding from the Natural Sciences and Engineering Research Council of Canada (NSERC), Mitacs, and the Manitoba Mineral Development Fund (MMDF).
“These early results are encouraging and reinforce our belief that geomicrobial techniques can provide powerful, low-impact insights in the search for buried mineral systems,” said Paul Sparkes, CEO of Integral Metals.
In parallel, rock, soil, and plant geochemical samples collected during the same 2024 program are currently undergoing analysis at the Saskatchewan Research Council (SRC). The integration of geomicrobial and geochemical datasets will inform exploration targeting and help prioritize areas for future drilling.
Integral Metals is committed to advancing critical mineral discovery using innovative, science-driven techniques that reduce environmental impact and improve targeting precision.
