Bonterra Congratulates Gold Fields on Securing Environmental Approval for the Windfall Project
Bonterra advances the Urban-Barry camp development after its Windfall permit cleared a significant regulatory hurdle.
Bonterra Resources Inc. (BTR) issued a congratulatory statement to partner Gold Fields Limited upon receiving the Certificate of Authorization to begin construction of the adjacent Windfall Project in Québec. This regulatory milestone follows the signing of the Uukiimau Impact Benefit Agreement with Cree First Nations in June 2026.
Bonterra retains a joint venture interest in the adjacent Phoenix Project, where Gold Fields can earn a 70% interest by incurring C$30 million in work expenditures by November 2026. The release references the October 14, 2026 Preliminary Economic Assessment (PEA) for the Barry Project, highlighting a C$665 million after-tax NPV and 54% IRR at a US$3,500/oz gold price assumption. Management emphasized the strategic alignment of the Urban-Barry camp's development and the long-term potential of Bonterra's asset base.
The announcement confirms expected regulatory progress for the joint venture partner’s flagship project, a milestone that validates the broader camp development narrative and supports the JV’s long-term value proposition. This development serves as a follow-up to prior permitting announcements and the impact benefit agreement established in June 2026. The news aligns with the November 2026 earn-in deadline and provides no new financial data, nor does it alter the C$30 million expenditure requirement or the company’s immediate liquidity position.
The Barry Preliminary Economic Assessment (PEA) metrics referenced in the report are contextual and rely on a highly speculative gold price assumption of US$3,500/oz. The PEA was already disclosed on October 14, 2026, and does not constitute a bankable feasibility study or a development decision under the joint venture agreement. Consequently, the announcement does not trigger an immediate change in Bonterra Resources Inc.’s (BTR) ownership, cash flow, or operational obligations.
Bonterra Resources Inc. (BTR) is a Québec-based gold exploration company focused on the Urban-Barry camp and the Desmaraisville South property. The company’s Urban-Barry operations are managed through a joint venture with Gold Fields Limited, the successor to Osisko Mining. This Phoenix JV covers the Barry and Gladiator deposits, with Gold Fields holding the right to earn a 70% interest by spending C$30 million by November 2026.
The Barry Project is a 100% owned mining lease covering 1.2 million tonnes, with permits for open pit and underground extraction. The site saw historical production of approximately 44,000 oz Au between 2008 and 2010. An October 2026 Preliminary Economic Assessment (PEA) outlines a 7.2-year mine life, a total capital cost of C$480.3 million, and an after-tax NPV of C$665 million at US$3,500/oz.
Desmaraisville South is also 100% owned and includes the Bachelor and Moroy deposits. A February 2026 Mineral Resource Estimate (MRE) reports 228 koz Measured & Indicated at 3.98 g/t Au. The Bachelor Mill, currently operating at 800 tpd, has permitting underway for expansion to 1,800 tpd. Additionally, the company maintains a joint venture with Agnico Eagle at Nelligan.
