NexGold Goldboro drilling uplift: resource and feasibility notes for mine planners

30 Second Briefing
NexGold Mining is increasing 2026 drilling at the fully permitted Goldboro project in Nova Scotia by one-third to 40,000 metres after reverse circulation infill holes in the West pit, including RC-26-147 (6 metres at 12.06 g/t from 44 metres, with 1 metre at 67.41 g/t) and RC-26-102 (18 metres at 3.84 g/t from 44 metres), confirmed near-surface continuity and tenor. The 3,420-metre, 72-hole RC campaign is about 62% complete and will feed a resource update, an updated feasibility study due in Q3 and a potential construction decision this year. A 2022 study on Goldboro, now combined with the Goliath gold complex in NexGold’s portfolio, outlined ~100,000 oz/year over 11 years with a 26% after-tax IRR at a 5% discount rate, with economics likely stronger at current gold prices.
Technical Brief
- Reverse circulation infill drilling totals 3,420 metres across 72 holes focused on the proposed West pit.
- Key shallow intercepts include 10 m @ 4.13 g/t from 11 m (RC-26-129) and 7 m @ 9.31 g/t from 25 m (RC-26-144).
- Near-surface mineralisation continuity within early pit phases is being resolved at a higher spatial detail than previous campaigns.
- Goldboro comprises two fully permitted open-pit deposits about 175 km northeast of Halifax, simplifying pre-construction sequencing.
- National Bank Financial flags reduced risk in early-years production, mine planning and project financing from the new data.
- The 2021 resource stands at 21.6 Mt measured and indicated @ 3.52 g/t (2.58 Moz) plus 3.18 Mt inferred @ 4.73 g/t (484 koz).
- A 2022 feasibility study assigned a US$328 million net asset value at a 5% discount rate and 26% after-tax IRR.
- Rising gold prices since 2022 are expected to improve project economics relative to the original feasibility base case.
Our Take
Goldboro’s 2.58Moz measured and indicated resource at 3.52 g/t puts NexGold into the mid-tier project bracket in our database, where feasibility-stage Canadian gold assets with similar grade and scale have tended to attract interest from larger producers once permitting and mine design are largely de-risked.
The shallow, high-grade intercepts reported from the West pit (starting around 10–50 m downhole) imply potential for an early high-margin open-pit phase, which, if confirmed in updated economics, could materially improve the 26% after-tax IRR outlined in the 2022 study and support project financing discussions with groups like National Bank Financial.
