Focus Graphite’s Lac Tetepisca resource: capex and pit geometry notes for engineers
Reviewed by Joe Ashwell

30 Second Briefing
Focus Graphite’s Lac Tetepisca project in central Quebec now hosts 14.7 million tonnes of contained graphite at 10.2% Cg, an 86% increase over its 2022 resource, ranking fifth globally and second in North America by contained tonnes. The updated estimate, based on 26,095 metres of drilling in 150 holes, includes 12.3 million tonnes contained graphite in measured and indicated resources (120.1 million tonnes at 10.27% Cg) plus 2.3 million tonnes inferred (24.1 million tonnes at 9.88% Cg). Grades above 10% Cg, open-pit geometry with favourable strip ratios, low-cost Quebec hydropower and planned >99.9% purity processing underpin analyst views that Focus trades at an 81% discount to peers.
Technical Brief
- Resource update is constrained by 26,095 m of core drilling across 150 holes on MOGC.
- Lac Tetepisca lies ~800 km northeast of Montreal within the Manicouagan-Ouest Graphitic Corridor and SW extension.
- Analyst notes both Lac Tetepisca and Lac Knife are open-pit deposits with favourable strip ratios.
- Reported grades at Lac Knife (15.4% Cg) and Tetepisca “far exceed” typical 3–5% Cg Chinese operations.
- Quebec hydropower is emphasised, with electricity typically forming 10–20% of graphite mine operating costs.
- Focus secured C$14 million government funding in December to build an ultra-high-purity (>99.9% Cg) processing plant.
- Targeted ultra-high-purity output is aimed at military, defence, aerospace and advanced technology applications.
- Equity market values Focus at about US$4 per tonne contained graphite versus a sector average of US$21/t.
- Globally, Lac Tetepisca’s contained graphite is benchmarked against Balama North/Nicanda Hill, Sarytogan, Mahenge and Graphite Creek.
Our Take
With Focus Graphite’s Lac Tetepisca now ranking alongside large resources such as Sarytogan (Kazakhstan) and Graphite Creek (Alaska), Quebec is emerging in our database as one of the few jurisdictions outside China and Africa that can host globally significant natural graphite clusters tied to lithium-ion batteries.
Northern Graphite’s planned US$200 million anode plant at Yanbu and the restart of Kearney in Ontario show that downstream and restart capital is already being committed for North American graphite; a 14.7 Mt contained graphite inventory in Quebec positions Focus as a potential future feedstock candidate for similar value-added processing hubs in Bécancour or the US.
The 81% valuation discount to the sector average on a per-tonne basis, despite Lac Tetepisca’s above-typical grades and scale, signals that early-stage Quebec graphite developers are still being priced as high-risk compared with peers in our graphite coverage, which may give strategic buyers or offtakers leverage in negotiations over the next funding steps.
