LIBRA ENERGY ANNOUNCES GRAPHITE DISCOVERY AT STIMSON PROJECT IN ONTARIO - DRILLS 4.7% GRAPHITIC CARBON OVER 14.7 METRES

Libra Energy Materials Inc. has released assay results from its maiden diamond drilling program at its 100-per-cent-owned Stimson project, located approximately 26 kilometres east of Cochrane, Ont. Although the single-hole program was designed to test a historical possible spodumene occurrence (see company press release dated Feb. 2, 2026), drill hole ST26-001 intersected a significant zone of graphitic mineralization, hosted within a graphitic metasedimentary unit.

Highlights:

• 4.7 per cent graphitic carbon over 14.7 metres intersected in hole ST26-001 (175.32 metres to 190 metres), including samples up to 10.45 per cent Cg (179.0 metres to 179.43 metres);
• Confirms a graphite-bearing system at Stimson; warrants follow-up evaluation of flake size, extent and scale;
• Additional broad zones of zinc mineralization, returning 0.52 per cent zinc over 18 m (159 metres to 177 metres) coincident with the graphite mineralization;
• Excellent infrastructure advantage: only 26 km east of Cochrane, with road access and proximity to rail, power and established mining services.

"The results from our maiden drill program at Stimson were unexpected in the best possible way. While the hole did not return spodumene as anticipated, it delivered a compelling graphite intercept. We are only one hole into this system, yet the thickness and grade already compare favourably to many early-stage graphite discoveries in the Superior craton. This provides significant upside potential for the company," commented Koby Kushner, chief executive officer of Libra. "Graphite remains secondary to our primary lithium strategy, but the discovery meaningfully enhances the value of Stimson. With excellent infrastructure and strong community support, we believe the asset is highly attractive for potential partners. Meanwhile, we continue to advance our large portfolio and look forward to drill results from our Penelope project in Brazil next (see company press release dated March 16, 2026)."

Stimson drilling overview

The 2026 winter program at Stimson consisted of a single diamond drill hole (ST26-001), totalling 203 metres. The hole was designed as a follow-up to historic Noranda exploration hole PT94-11 (1994), which had intersected pegmatite dikes previously interpreted as possibly spodumene bearing. While the pegmatites encountered in ST26-001 were confirmed to be barren of significant lithium (values ranging from three to 116 parts per million lithium across 84 samples), the hole intersected a meaningful zone of graphite mineralization within the surrounding graphitic metasedimentary package. This unexpected result opens a new commodity vector on the property.

Graphite results

The reported graphitic interval represents a weighted-average grade calculated from continuous sampling across a partially healed fault zone in graphitic metasediments. Carbon assays were obtained using ALS Geochemistry method C-IR18 (graphitic carbon by induction furnace following HCl leach and roasting to remove carbonate and organic carbon). A summary of carbon assay statistics for hole ST26-001 is provided below.

Many drill holes completed historically by Noranda on the property are also recorded as having intersected graphitic metasedimentary units (assessment record 42H02SE0010), suggesting that graphite-bearing horizons may extend across multiple claims and represent a regionally developed feature warranting systematic exploration.

Follow-up plans (next steps):

• Following the encouraging results from ST26-001, Libra is evaluating the Stimson project as a polymetallic exploration opportunity; proposed next steps include: surface prospecting program to refine the geological model and trace graphitic horizons along strike;
• Relogging and review of historical drill holes that intersected graphitic metasedimentary units;
• Compilation of geophysical and geochemical data across the southern claim block to define drill-ready targets for graphite, base metals and precious metals.

No additional drilling is planned at this time by Libra at Stimson. The company may provide updates as surface work and data compilation progress and may consider seeking a partner to advance the project while Libra maintains its primary focus on lithium exploration in Canada and Brazil.

Quality assurance/quality control

Drill core was logged and sampled at Bayside Geoscience's facility in Thunder Bay, Ont. A total of 160 samples (151 rock samples and nine standards) were submitted to ALS Geochemistry's preparation lab in Thunder Bay and analyzed at ALS's Vancouver laboratory, an ISO/IEC 17025 accredited facility independent of the company. Gold was determined by 30-gram fire assay with AAS finish (Au-AA23), graphitic carbon by HCl leach, roast and induction furnace IR detection (C-IR18), and lithium and trace elements by sodium peroxide fusion ICP-MS (ME-MS89L). Certified reference materials, blanks and field duplicates were inserted into the sample stream and reviewed for performance prior to release of results.

True widths of the reported interval are not yet known and will be refined following structural interpretation. Reported intervals are core lengths.
