New Brunswick Critical Minerals Strategy 2026: Deposits, Projects and Responsible Growth

New Brunswick entered 2026 with a new Comprehensive Minerals Strategy, renewed exploration interest and several deposits connected to clean technology, advanced manufacturing and defence supply chains. The province’s goal is ambitious: become Canada’s leading jurisdiction for competitive and sustainable mineral exploration and development.

The opportunity includes tungsten and molybdenum at Sisson, polymetallic deposits at Murray Brook, manganese near Woodstock, and reported occurrences of gold and lithium. Converting geological potential into durable economic value will require more than permitting speed. Environmental performance, Indigenous partnerships, infrastructure, financing and community confidence are central to whether projects advance responsibly.

New Brunswick’s critical-minerals opportunity at a glance

Why critical minerals matter now

Critical minerals are inputs for electricity systems, electronics, aerospace, defence, batteries and advanced industrial components. Global demand and national-security concerns have increased attention on reliable, responsibly produced supply from trusted jurisdictions.

New Brunswick’s advantage is not only the presence of minerals. The province also points to decades of geoscientific information, skilled workers, roads, ports and access to North American and transatlantic markets. These assets can reduce certain development barriers, although each deposit has its own geology, economics and environmental context.

Sisson is the leading proof point

The proposed Sisson project north of Fredericton contains tungsten and molybdenum, both on Canada’s critical-minerals list. In August 2025, Natural Resources Canada announced $8.2 million to update the feasibility study and engineering design needed to support a construction decision. In November, the project was added to the federal nation-building projects list.

The Government of New Brunswick stated that construction could employ up to 500 people and operations up to 300 over an expected 27-year mine life. Those are project expectations, not confirmed outcomes. A final decision still depends on technical work, financing, approvals, market conditions and the project’s ability to meet environmental and community commitments.

A broader mineral portfolio reduces dependence on one project

The March 2026 strategy highlighted the Murray Brook deposit near Bathurst, which contains zinc, lead, copper and silver, as well as manganese in the Woodstock area. Gold and lithium occurrences expand the exploration narrative. This variety is important because mineral prices, processing requirements and end markets differ.

A diversified pipeline can support geoscience services, drilling, laboratories, environmental consulting, engineering, construction and transport before a mine enters production. It can also create opportunities to explore value-added processing, provided energy, scale and commercial economics support it.

Predictability and responsibility must advance together

The province plans a modernized Mining Act intended to create a more agile, predictable and timely regulatory system. Predictability can help investors understand requirements and timelines. It should not be confused with lower standards. Durable projects need clear environmental assessment, water management, closure planning, financial assurance and transparent public reporting.

Meaningful partnerships with Indigenous communities are equally important. Early engagement, respect for rights, shared decision-making and opportunities for ownership, employment or procurement can improve project design and distribute benefits more fairly. These relationships cannot be reduced to a final-stage consultation exercise.

Infrastructure connects deposits to markets

Mineral development depends on roads, electricity, digital connectivity, rail and ports. New Brunswick’s deepwater ports at Saint John and Belledune, plus connections to central Canada and the United States, can support equipment movement and eventual exports. Federal trade-corridor programs are also giving greater priority to infrastructure that unlocks critical-mineral supply chains.

The strongest opportunity is therefore a system: geology plus power, transportation, processing capability, skilled people and public confidence. Focusing only on what is underground understates both the potential and the work required.

What to watch through 2026 and beyond

• Introduction and details of the modernized Mining Act.
• Updated engineering, feasibility and financing milestones for Sisson.
• Exploration results and claim activity across the province.
• Indigenous partnership and benefit structures.
• Investments in roads, energy and trade corridors.
• Opportunities for local suppliers and value-added processing.
