St Barbara Lifts Nova Scotia Exploration Spend 64% as 105-Hole Drill Campaign Launches
St Barbara lifts Nova Scotia gold exploration spend 64% to $4.1 million as drilling program launches
St Barbara Limited has launched an accelerated exploration program in Nova Scotia, increasing its exploration budget 64% from $2.5 million in FY26 to $4.1 million in FY27. The investment drives a drilling campaign of up to 105 RC and IFRC holes for 4,400 metres across five to seven targets — a material step-up from zero drilling in FY26 — as the company advances a 58-target pipeline across its 681 km² tenement package.
The program targets mine-life extensions beyond the current 11-year plan at the proposed 15-Mile Processing Hub Project, with the exploration team doubled in size and further expansion anticipated for FY28. Drilling is scheduled to commence mid-August 2026 and take up to two months to complete, subject to prior consultation with First Nation and local community.
The scale of the opportunity
St Barbara’s Nova Scotia tenement position comprises 172 exploration licences, 4,206 claims, and 68,095 hectares (681 km²), plus one mining lease. The package contains 58 active exploration targets, with 46 located within a 75 kilometre radius of the 15-Mile Processing Hub. The Touquoy mine is planned to restart by December 2026.
FY27 accelerated program highlights:
- Budget: $4.1 million (+64% from FY26)
- Team: Doubled in size, with further FY28 expansion planned
- Drilling: Up to 105 RC/IFRC holes for 4,400 metres (versus none in FY26)
- Surface sampling: >2,000 samples (+80% from 1,100 in FY26)
- Prospectivity study: Terrane-wide targeting review covering >40,000 km²

Where the drill rigs are heading
The RC and IFRC drilling program splits into three components: Resource Extension RC drilling at 15-Mile (up to 8 holes for 1,000 metres) testing depth extensions at the Egerton-McLean, Hudson and Plenty deposits; Exploration RC drilling within the 75 kilometre radius at Dufferin, Isaac’s Harbour and Lower Seal Harbour (up to 21 holes for 1,500 metres); and Reconnaissance IFRC drilling at Patton, Falcon and Little Meander (up to 76 holes for 1,900 metres).
| Target | Drill Type | Holes / Metres | Rationale | Notable Historical Result |
|---|---|---|---|---|
| 15-Mile (Egerton-McLean, Hudson, Plenty) | RC Resource Extension | up to 8 holes / 1,000 m | Depth extensions | — |
| Dufferin | RC | 3 holes / 450 m | 500 m strike test west of NI 43-101 Inferred Resource | — |
| Isaac’s Harbour | RC | up to 6 holes / 750 m | Northern limb/fold axis | 31.9 g/t Au rock chip; 39,694 oz historical production; 3 km from NexGold’s Goldboro |
| Little Meander | IFRC | up to 10 holes / 250 m | Fenceline | 13.25 g/t Au rock chip |
| Falcon | IFRC | up to 24 holes / 600 m | NE anticline | 200 ppb Au till |
| Patton | IFRC | up to 42 holes / 1,050 m | Goldenville/granite contact; Au-Sn-In target | 34.1 ppb Au till; 6 km from East Kemptville Tin Mine |
| Lower Seal Harbour | IFRC | up to 12 holes / 300 m | E-W anticline | — |
The Patton program carries a de-risking element: a C$100,000 Mineral Resources Development Fund grant from the Nova Scotia Department of Natural Resources and Renewables covers 50% of program costs.
Understanding Meguma-style gold
St Barbara’s Nova Scotia deposits are textbook examples of turbidite-hosted mesothermal gold, a globally recognised deposit type analogous to the Victorian Goldfields (Australia), New Zealand’s Torlesse and Buller terranes, and California’s Motherlode belt.
Gold concentrates in anticlines — structural folds in the rock where sedimentary layers have been compressed and bent upward. The gold occurs within quartz veins and disseminated mineralisation hosted in the fold axes and limbs of these anticlines. St Barbara’s tenements cover 164 line kilometres of anticlines inside the 75 kilometre radius of the 15-Mile Processing Hub, with 75 line kilometres mapped where the prospective Moose River Formation occurs at surface or under shallow till cover.
The exploration workflow follows a staged approach: surface sampling (till and rock chip) identifies anomalies, which are tested by IFRC fenceline drilling to intersect bedrock mineralisation, then advanced targets progress to deeper RC or diamond drilling. This is a repeatable, well-understood model across a large tenement package, lowering geological risk across the target pipeline.
Building the pipeline — sampling, geophysics and a terrane-wide study
Surface sampling scaled up
The company has increased surface sampling by more than 80%, from 1,100 samples in FY26 to more than 2,000 samples in FY27. Sampling is split 70% around the 15-Mile Hub and 30% regional, testing up to 14 targets across the portfolio. The program runs from May to September 2026.
Geophysics and structural work
- ~50 km² UAV magnetic survey (~2,080 line kilometres) across 15-Mile, Old Austen Mine and Touquoy, scheduled for Q2 December FY27.
- 3D magnetic inversion models for all four deposits (15-Mile, Old Austen Mine, Old Mitchell Mine and Touquoy).
- Detailed structural review by a specialist consultant to define near-mine FY28 drill targets from diamond drill hole data.
Meguma Terrane prospectivity study
A gold prospectivity and targeting study covering the entire Meguma Terrane (>40,000 km²) is underway, with delivery expected in H2 FY27. Precursor geophysical grids were generated in Q4 FY26. The study aims to generate, for the first time, a single solid geology (lithostructural) map covering the Meguma Terrane.
The study will integrate all available geological, structural and geophysical data to generate gold prospectivity ‘heat’ maps, re-rank the 58-target pipeline, and identify new targets for H2 FY27 and FY28 follow-up programs.

What it means for investors and what comes next
St Barbara has committed a modest $4.1 million to systematically test a large, geologically proven package with high-grade historical hits. The target is mine-life extension beyond the current 11-year plan at a hub already at pre-feasibility stage. The investment supports an aggressive work program that doubles the exploration team, triples drilling metres, and applies advanced targeting tools across a 681 km² tenement position containing 164 line kilometres of anticlines.
The leverage is clear: multiple targets with historical high-grade rock chip results (31.9 g/t Au at Isaac’s Harbour, 13.25 g/t Au at Little Meander) located within economic trucking distance of a central processing hub. Each discovery adds incremental mine life and improves project economics.
Andrew Strelein, Managing Director and CEO
“St Barbara has previously announced the acquisition and pegging of attractive areas of known gold mineralisation that hosts numerous targets within 75 kilometres around the 15-Mile Processing Hub Project in Nova Scotia, while continuing to advance our development of the currently defined eleven year plus production centre. We can now share the high intensity work program that we have had underway commencing in the last quarter that will extend to June 2027. This 64% increase in exploration spend and doubling of the exploration team will allow us to maximise the opportunities we have in Nova Scotia.”
