As global demand for energy storage continues its upward trajectory, the scramble to secure reliable, ethical, and scalable supplies of battery‑grade materials has become one of the defining challenges of the decade.
Graphite—still the largest component in a lithium‑ion battery by weight—sits at the centre of this shift. While Asia remains the world’s dominant supplier, North America’s battery supply chain is accelerating rapidly, fuelled by industrial policy, targeted investment, and the push for localized, low‑carbon mineral production. In this climate, few jurisdictions shine as brightly as Québec, whose stable regulatory environment, abundant hydroelectric power, and mining‑friendly infrastructure have positioned it as a future cornerstone of Western graphite production.
Into this landscape enters Lomiko Metals Inc. (TSX.V:LMR), which has now delivered a strongly positive Preliminary Feasibility Study (PFS) for its wholly-owned La Loutre Graphite Project in southeastern Québec. Completed by DRA Global in accordance with National Instrument 43‑101, the PFS outlines a long‑life, economically robust operation with metrics that place La Loutre among the more compelling emerging graphite development projects in North America.

A PFS with strong economics and long-term production stability
According to the PFS, the La Loutre Project delivers at 8% discounted a pre‑tax NPV (8%) of C$797.5 million and a 30.3% IRR, with a post‑tax NPV (8%) of C$617.4 million and a 24.7% IRR, based on a long‑term graphite concentrate price of US$1,524/t Cg. These economics translate into rapid capital recovery: a 3.1‑year pre‑tax payback and 3.2‑year after‑tax payback, supported by an initial capital expenditure (CAPEX) of C$504.6 million.
Probable mineral reserves, defined at a 1.50% graphitic carbon (Cg) cut‑off grade, total 46.8 Mt at 4.79% Cg, containing 2.24 Mt of in‑situ graphite—a solid foundation for a long‑duration operation. Over the 28‑year life of mine (LOM), the mill is expected to process 46,803 kt of feed, yielding 2,149 kt of graphite concentrate grading 97% Cg with an average 93% recovery.
The strip ratio remains competitive at 2.4:1, supporting cost‑effective mining. Average annual concentrate production is projected at 79.6 kt, with the first 20 years averaging ~97 kt per year before tapering as zones are depleted.
Stable location in Québec’s growing battery materials corridor
La Loutre sits within the Nominingue‑Chénéville Deformation Zone in south‑central Québec, a region increasingly recognized for its graphite endowment. The property covers 76 mineral claims over 4,528 hectares, approximately 200 km northwest of Montreal and within driving distance of established and emerging graphite operations such as Nouveau Monde Graphite’s Matawinie Project and the Imerys Lac‑des‑Îles mine.
This proximity to infrastructure, skilled labour, and renewable hydroelectricity enhances La Loutre’s potential as a low‑carbon, North American source of battery‑grade material.
A multi‑disciplinary PFS led by expert engineering teams
The PFS reflects an integrated effort by established consulting groups:
- DRA Global led the NI 43‑101 process, completed the plant design and infrastructure engineering, and compiled the PFS report.
- Norda Stelo handled geology, mineral resources, mine design, water management, and environmental studies.
- Knight Piésold delivered geotechnical design for waste facilities, pit slope recommendations, groundwater inflow modeling, and geochemical characterization of materials.
- Metpro Management reviewed metallurgical test work performed by SGS Canada.
Together, these firms provide a strong technical backbone, ensuring the study’s conclusions rest on conservative, industry‑standard assumptions.
Mining, processing, and infrastructure: A conventional, low‑risk design
Mining will utilize conventional open-pit methods, with operations scheduled over ten months each year. The design features two pits—the EV and Battery zones—each with five phases. The 1.73 Mt/year process plant relies on standard flotation technology, producing a high‑purity 97% Cg concentrate that is sorted into market‑aligned size fractions.
Environmental stewardship is built into the design:
- Filtered tailings reduce water consumption,
- Co‑disposal of tailings and waste rock promotes long‑term stability,
- Water recycling systems minimize fresh water intake, and
- Progressive backfilling and noise berms mitigate operational impacts.
The combination of filtered tailings and renewable power availability positions La Loutre as a future low‑emissions contributor to the graphite supply chain.
Resource base and long-term potential
The February 19, 2026, Mineral Resource Estimate includes both the EV and Battery zones. At the base case 0.95% Cg cut‑off, measured and indicated resources total 69.96 Mt at 4.41% Cg containing 3.08 Mt of graphite, with an additional 20.28 Mt inferred at 3.53% Cg containing 716 kt of graphite.
While only a portion of these resources are currently included in the reserve base, the scale suggests potential future mine life extensions or production uplifts, subject to further drilling and engineering.
U.S. Defense Production Act funding strengthens already stable position
Notably, this PFS and baseline data collection were supported by a US$8.35 million award under Title III of the U.S. Defense Production Act—a clear indicator of the major importance of North American graphite production. Phase 1 is now complete, with future phases supporting the path toward feasibility and commercialization.
Next steps: Toward feasibility and environmental approvals
The PFS recommends advancing La Loutre to a full Feasibility Study (FS) and completing a comprehensive Environmental Impact Study. Additional metallurgical work, trade‑off studies, and on‑site field programs will refine capital and operating assumptions and continue derisking the project.
With strong economics, a long mine life, and supportive government frameworks, La Loutre is positioned to advance steadily along the development pipeline.
Leadership insights
“Since the original PEA was published in 2021, we have completed significant engineering work to better define the project footprint and resource base, resulting in the updated resources, declaration of reserves, development of project infrastructure, and design plans for the project with the aim of minimizing the footprint and creating a compact, environmentally responsible, and sustainable project,” Lomiko’s CEO and director, Gordana Slepcev explained in a media statement. “At the same time, this study demonstrates the strong economic leverage the project possesses, and clearly demonstrates the potential for La Loutre to be a large economic driver in southern Québec and Canada with the mine life spanning for 28 years delivering hundreds of jobs and careers in the region, significant contracting opportunities for regional and Indigenous businesses and more than C$4.7 billion in revenue, as well as generational opportunities for local residents and the Indigenous community in the area.”
CEO Slepcev elaborated on this even further in an exclusive interview with The Market Online’s Ricki Lee on “The Watchlist”, which you can watch in full by clicking the video below.
