--- title: "Windfall Gold Project Receives Environmental Approval | BBA" date: 2026-11-12T15:40:00-05:00 author: Justas Gasiunas canonical_url: "https://www.bbaconsultants.com/en-us/news/windfall-reaches-a-key-milestone-with-its-environmental-authorization" section: News --- Gold Fields’ Windfall gold project has just reached a major milestone with the granting of its environmental authorization by the Government of Québec. BBA is already fully engaged in the project and is deploying about 170 people each week to carry out the detailed engineering, which is now more than 50% complete. 1. Located in the Eeyou Istchee James Bay region, Windfall is one of the highest-grade gold projects in Canada. The certificate of authorization now makes it possible to begin construction activities, in accordance with applicable conditions, commitments and regulatory requirements. At full capacity, Gold Fields expects to produce approximately 300,000 ounces of gold per year. ## A wide range of expertise at work BBA is carrying out the detailed engineering and design for the processing plant, including the ore crushing and material handling, milling, leaching, gold recovery and refining circuits. Our mandate also includes tailings filtration, paste plant and water treatment facilities, as well as site-wide electrical distribution, telecommunications, automation, instrumentation and control systems. In addition, the scope includes several non-process infrastructures, such as a permanent camp and selected site facilities. ***“Obtaining this authorization marks an important turning point for Windfall. A project of this scale depends on the ability to bring many disciplines together in an integrated way. This collaboration across our areas of expertise is what allows us to make a tangible contribution to its progress.” -*** Isabelle Leblanc, Vice-President, Mining and Metals The authorization is the result of several years of environmental and social studies, technical analyses, dialogue with communities and collaboration with government authorities. It also follows the signing, in June 2026, of the Uukiimau Agreement between Gold Fields, the Waswanipi Cree First Nation, the Cree Nation Government and the Grand Council of the Crees. Windfall is entering a new phase with this authorization now in place. Our teams are already fully engaged and will continue to work closely with Gold Fields to advance the project. ## About BBA BBA Consultants has been a trusted partner in the energy and natural resources sector for more than 45 years.
