Focus Graphite Announces Final Results From 2022 Drill Program at Lac Tetepisca; West Limb Extends Mineralized Strike to 8 KM
Press Release
Ottawa, ON, December 18, 2025 – Focus Graphite Inc. (TSX.V: FMS | OTCQB: FCSMF | FSE: FKC0) (“Focus” or the “Company”), a leading developer of high-grade flake graphite deposits and innovator of next-generation lithium-ion battery technology, reports the final assay results from its 2022 exploration and definition drilling program at the Company’s 100%-owned Lac Tetepisca Graphite Project (the “Project”). Today’s disclosure includes results from the remaining twenty-two (22) drill holes on the West Limb, along with complementary results from six (6) previously disclosed holes in the Southwest extension of the Manicouagan-Ouest Graphitic Corridor (“MOGC”) flake graphite deposit.
These results extend the drilled strike length of mineralization to approximately eight (8) kilometers along a folded structure. All assay results from the 2022 drill campaign have now been received and released.
Highlights
- Final assay results received from the Focus’s 2022 Lac Tetepisca drill program drill program have now been received, completing 74 drill holes totalling 14,900.5 meters and 11,824 assays and enabling the Company to proceed with an updated Mineral Resource Estimate in Q1 2026.
- Results from the 22 West Limb and 6 Southwest MOGC holes extend confirmed graphite mineralization along a approximately 8-km strike length, significantly expanding the scale of the Lac Tetepisca system.
- Multiple West Limb holes returned significant graphite intervals, more or less aligned on strike along one of the aeromagnetic anomalies, including:
- 16 m (true) @ 9.02% Cg, including 10.50 m @ 24.49% Cg (LT-22-160)
- 55 m (true) @ 8.90% Cg and 24.97 m (true) @ 6.43% Cg (LT-22-161)
- 98 m (true) @ 8.17% Cg and multiple additional mineralized horizons (LT-22-162)
- Drilling at the Southwest MOGC intersected a second, structurally distinct mineralized horizon, highlighted by:
- 19 m (true) @ 9.71% Cg, including 8.61 m @ 14.76% Cg (LT-22-141)
- Completion of the full assay dataset represents a major technical milestone, positioning Focus to reassess the scale, continuity, and development potential of Lac Tetepisca as it advances toward metallurgical, purification, and downstream application testing.
Dean Hanisch, Chief Executive Officer of Focus Graphite, stated, “The completion of all assays from our 2022 drilling program provides the complete dataset required to advance an updated Mineral Resource Estimate, anticipated in Q1 2026. The current maiden resource predates all 2022 drilling, and the results confirm meaningful upgrade potential across the Lac Tetepisca system.”
While mineralized intervals intersected in the West Limb are not to the same extent than those in the main MOGC deposit, it demonstrated the continuity of the broad low grade graphitic mineralization in this area, at a different stratigraphic level than on the South Limb where MOGC is located. The extent of this low-grade zone is apparently sufficient to be considered in the incoming Mineral Resource Estimate (“MRE”) update planned for Q1 2026.Despite being lower grade, definition of, “significant mineralization” is defined as intercepts grading ≥5.0% graphitic carbon (“Cg”) over a minimum true thickness of 6.0 metres, with internal dilution set at a maximum of 7.0 consecutive metres and no external dilution. This definition has been maintained to be consistent with previous releases.
MOGC Resource Background
The MOGC flake graphite deposit is part of the Company’s Lac Tetepisca Project, located southwest of the Manicouagan Reservoir on the Nitassinan of the Pessamit Innu First Nation, in Quebec’s Cote-Nord region. The MOGC is currently defined by a linear 1.5 km long segment of an 8 km long folded geophysical magnetic-electromagnetic anomaly that trends N035°. The April 4, 2022 NI 43-101 Technical Report, prepared by DRA America’s Inc. (“DRA”), outlines a pit-constrained Indicated Resource of 59.3 million tonnes (Mt) grading 10.61% Graphitic Carbon (Cg) for an estimated content of 6.3 Mt of natural flake graphite (in-situ), and an Inferred Resource of 14.9 Mt grading 11.06% Cg for an estimated content of 1.6 Mt of natural flake graphite. This maiden resource predates all drilling completed in 2022. An updated MRE incorporating all 2022 drill holes is expected in Q1 2026.
The current maiden resource—which positions the MOGC as one of the largest flake graphite deposits in North America—is detailed in the NI 43-101 Technical Report Mineral Resource Estimate Lac Tetepisca Graphite Project, Quebec, prepared by DRA and dated April 4, 2022. The reporst is available on the Company’s profile at www.sedarplus.ca/ on the Company’s profile. This maiden resource predates all drilling completed in 2022. As demonstrated in previous releases, the 2022 drill program extended the mineralization at depth and to the southwest, and now to the West Limb.
2022 Exploration and Definition Drill Program
Focus completed 74 diamond drill holes totalling 14,900.5 metres between March 3 and November 17, 2022 at the Project. Program objectives of the exploration and definition drilling program were twofold:
- Complete systematic definition drilling along strike and at depth of the MOGC deposit to support the conversion of Inferred resources to the Indicated category and to expand the total mineral resource estimate.
- Test the graphite abundance that might be the cause of the magnetic and aeromagnetic anomaly extending from the MOGC toward the Southwest extension and West Limb.
Prior to this release, the Company disclosed full results from twenty-seven (27) definition holes drilled along strike of the MOGC deposit, partial results for eighteen (18) exploration holes at the Southwest MOGC target and seven (7) exploration holes at the West Limb target.
The remaining results from West Limb (22 holes, Table 1, Figure 1) and Southwest MOGC (6 holes, Table 3, Figure 1) are provided herein. All assays results for the 2022 campaign are now complete.
Also included are minor corrections of previously released results for two (2) West Limb holes (Table 2, Figure 1).
One aborted hole (LT-22-147) in the Southwest MOGC target was abandoned due to technical/drilling difficulties and was successfully re-drilled and under the LT-22-172 moniker.
