Swanson gold results and 6.05 g/t hit: project economics and drilling lens for engineers

30 Second Briefing
LaFleur Minerals’ latest drilling at the 19,214-hectare Swanson Gold project in Quebec’s Abitibi Belt yielded a standout intercept of 6.05 g/t gold over 8 m in hole SW-26-124 at the Bartec target, the first modern hole there since 1987, but overall continuity across Bartec, Jackson and Jolin remains weak. Jackson returned 1.45 g/t over 7.70 m in SW-26-111 along a 1,200 m mineralised corridor, while Jolin’s SW-26-103 cut 1.77 g/t over 6.45 m. Despite a March 2026 PEA giving Swanson a US$70.8 million NPV and 65% after-tax IRR, LaFleur’s share price has fallen over 18% since 22 September, with Bartec now prioritised for follow-up drilling.
Technical Brief
- Swanson tenement covers 19,214 hectares, comprising 464 mineral claims plus one mining lease.
- Project lies 66 km from Val-d’Or in the Abitibi Gold Belt, ensuring established mining infrastructure access.
- Three named gold-bearing zones (Bartec, Jackson, Jolin) are constrained by >36,000 m of historical drilling data.
- Bartec’s current hole is the first modern drill test there since 1987, indicating a large data gap.
- At Jackson, mineralisation is now traced along a 1,200 m west-northwest corridor from the historical showing.
- March 2026 preliminary economic assessment reports C$101 million NPV and 65% after-tax IRR for Swanson.
- Market reaction has been negative, with LaFleur’s share price down >18% since 22 September plus 2.86% Monday.
Our Take
Swanson’s location 66 km from Val-d’Or in the Abitibi Gold Belt aligns it with a cluster of brownfield and near-mine gold projects in northwestern Quebec in our coverage, where existing infrastructure and a mature permitting regime have tended to shorten development timelines compared with new camps in northern Canada.
The 464 mineral claims and single mining lease at Swanson suggest LaFleur is still balancing regional exploration upside with a more advanced core asset; in similar Abitibi gold cases in our database, operators have often pivoted capital towards the best-performing zone once early drilling clarifies which targets can support a standalone mine plan.
