Québec Certificate of Authorization Clears Path for Windfall Construction

The Québec government's issuance of a Certificate of Authorization to Gold Fields and its wholly owned subsidiary, Windfall Mining Group Inc., formally authorises construction of the Windfall Project. The release states this milestone follows the signing of the Uukiimau Impact Benefit Agreement with the Cree First Nation of Waswanipi, the Cree Nation Government, and the Grand Council of the Crees in June 2026. Bonterra describes the approval as a significant step toward development of the Windfall Project and notes it reinforces the region's potential to become a major gold mining district.

Phoenix JV Positions Bonterra Adjacent to Advancing Windfall Development

Bonterra's connection to the Windfall Project centres on its Phoenix JV, which is situated adjacent to the Windfall Project and governed by a definitive earn-in and joint venture agreement with Windfall Mining Group Inc., originally announced in November 2023. Gold Fields became Bonterra's counterparty following its acquisition of Osisko Mining in October 2024 for C$2.16 billion. Under the agreement, Gold Fields can earn a 70% interest in the joint venture by incurring C$30 million in work expenditures on or before November 2026, including expenditures previously incurred by Osisko Mining.

Barry Project PEA Adds Financial Context to Bonterra's Urban-Barry Portfolio

The announcement coincides with a broader period of activity for Bonterra. On October 14, 2026, the company released a Preliminary Economic Assessment for its Barry Project, outlining an after-tax net present value of C$665 million and an internal rate of return of 54% at a long-term gold price of US$3,500 per ounce. The company notes the PEA mine plan incorporates approximately 40% of contained gold ounces from its February 2026 Mineral Resource Estimate. Readers should note the PEA is preliminary in nature and there is no certainty its projections will be realised.
