Bonterra Resources Inc. ($BTR) Announces Updated Mineral Resource Estimates
Val-D'Or, Quebec--(February 23, 2026) - Bonterra Resources Inc. (TSXV: BTR) (OTCQX: BONXF) (FSE: 9BR2) is excited to share updated Mineral Resource Estimates (the "2026 MREs") for its Barry and Gladiator deposits. The estimates have been independently prepared by P&E Mining Consultants Inc. in accordance with National Instrument 43-101 and are effective as of February 18, 2026.
Marc-Andre Pelletier, President and CEO, stated: "The updated 2026 MREs prepared by P&E, combined with additional drilling completed since 2021, has resulted in a significant increase in Mineral Resources across all classifications for the Properties. Overall, the quality of the 2026 MREs has improved, highlighted by a 30% increase in Measured & Indicated Mineral Resources, along with important technical enhancements, including a more conservative Mineral Resource classification methodology and an increase in the minimum mining width from 1.20 m to 1.75 m, closely aligned with industry standards. Both deposits remain open at depth and along the eastern down-plunge, particularly at Barry, where two drill rigs are currently testing extensions of the mineralization. Most importantly, the Urban-Barry Camp continues to demonstrate its potential to host multiple multi-million-ounce gold deposits."
2026 MREs Details & Assumptions
The Geological interpretation and modeling of the deposits reveal significant details:
The Barry Mineral Resources Estimate is based on over 73 veins grouped within 10 vein sets extending from surface to 650 m in depth. Measured Mineral Resources were defined where proximal to historical pits and determined using three drill holes spaced up to 15 m apart. Indicated Mineral Resources are limited to areas defined using three drill holes spaced up to 30 m apart, while Inferred Mineral Resources represent areas with drill hole spacing up to 60 m. Open pit Mineral Resources are reported within an optimized pit at a gold cut-off grade of 0.3 g/t Au.
The Gladiator Mineral Resources Estimate is based on over 127 vein structures within 8 structural groups, with Block model grade estimates controlled by geological interpretations. Similar methodologies apply, with Measured, Indicated, and Inferred Mineral Resources classified based on drill hole spacing.
Mineralized domains were initially developed by Bonterra and reviewed by P&E. The Qualified Person (QP) considers the geological modeling and Mineral Resources classification consistent with industry practices. Further details regarding the 2026 MREs will be available on SEDAR+ within 45 days of this news release.
Gold Fields has an agreement to acquire a 70% interest in the Project by spending C$30 million in work expenditures, with a minimum commitment of C$10 million per year over three years. This strategic move underscores Bonterra's commitment to advancing its exploration assets.
The Barry and Gladiator project's drill core gold analyses are performed at Bachelor Mine Laboratory, Actlabs, and AGAT Laboratories, which employ rigorous QAQC analysis programs. The analyses are carried out by fire assay and atomic absorption finish, with independent verification samples sent to ALS Minerals laboratory.
Bonterra is a Canadian gold exploration company with a portfolio of advanced exploration assets anchored by a central milling facility in Québec. The Company's assets include the Gladiator, Barry, Moroy, and Bachelor gold deposits, collectively holding 1.401 million ounces of Measured & Indicated Mineral Resources at an average grade of 2.90 g/t Au.
