St Barbara Limited is ramping up its gold exploration in Nova Scotia, increasing its FY27 budget by 64% and doubling its exploration team to accelerate resource growth near the 15-Mile Processing Hub.
- 64% increase in FY27 exploration budget to A$4.1 million
- 105 planned RC and IFRC drill holes totaling 4,400 meters
- Over 2,000 surface samples to be collected across 14 targets
- High-resolution UAV magnetic surveys and 3D modelling underway
- Province-wide Meguma Terrane gold prospectivity study launched
Significant Budget and Team Expansion for Nova Scotia Exploration
St Barbara Limited (ASX:SBM) is dramatically stepping up its gold exploration efforts in Nova Scotia, committing A$4.1 million to its FY27 program; a 64% increase over FY26’s A$2.5 million. This boost accompanies a doubling of the exploration workforce, signalling the company’s intent to aggressively pursue extensions to its 11-year mine life at the 15-Mile Processing Hub and regional targets.
Managing Director Andrew Strelein highlighted the strategic value of the expanded pipeline, which now comprises 58 exploration targets across 681 square kilometres, including 46 within a 75-kilometre radius of the 15-Mile hub. The enhanced budget and personnel increase are designed to maximise the opportunities within this extensive tenement package.
Robust Drilling Campaign Targets Multiple Deposits
The FY27 drilling program is ambitious, with plans for up to 105 Reverse Circulation (RC) and Interface Reverse Circulation (IFRC) holes totaling 4,400 meters. This includes resource extension drilling at 15-Mile (up to 8 holes, 1,000 meters), exploration drilling at Dufferin, Lower Seal Harbour, and Isaacs Harbour (up to 21 holes, 1,500 meters), and reconnaissance IFRC drilling at Patton, Falcon, and Little Meander (up to 76 holes, 1,900 meters). Notably, no RC drilling occurred in FY26, marking a clear shift to an active field season.
The program is scheduled to commence in mid-August, with completion expected within two months, subject to access approvals and community consultations. The company has also secured a C$100,000 grant to fund half the costs of the Patton drilling program, underscoring regional support for exploration activities.
Geophysical Surveys and Structural Studies to Refine Targets
Complementing the drilling, St Barbara is conducting extensive geophysical work, including a high-resolution UAV magnetic survey covering approximately 50 square kilometres across the 15-Mile, Old Austen Mine, and Touquoy deposits. This survey will generate detailed magnetic images and 3D inversion models for four deposits, including Old Mitchell Mine, to enhance geological interpretations and drill targeting.
In addition, a specialist structural geology consultant will undertake a detailed review of diamond drilling data to identify near-ready drill targets in the brownfield environment. These efforts aim to refine the understanding of structural controls on mineralisation and unlock further resource extensions.
Surface Sampling and Province-Wide Prospectivity Study
Surface sampling is also being ramped up, with over 2,000 till and rock chip samples planned across 14 priority targets. Approximately 70% of this sampling will focus on the 15-Mile Processing Hub area, with the remainder targeting regional prospects. These programs will help identify anomalous gold zones for follow-up drilling.
Parallel to field activities, St Barbara has commissioned a comprehensive gold prospectivity and targeting study covering the entire Meguma Terrane, a 40,000 square kilometre geological province. This study integrates a variety of geophysical datasets and geological information to produce a unified lithostructural map and generate gold prospectivity heat maps. The results will update and prioritise the existing target pipeline to guide exploration in the second half of FY27 and into FY28.
Strategic Context and Next Steps
The expanded exploration program follows recent positive developments at the 15-Mile Processing Hub, where St Barbara recently lifted Mineral Resources by 20% to 2.5 million ounces of gold, driven by updated geological models and historical drill data. This exploration acceleration fits within the company's broader strategy to underpin and potentially extend the mine life beyond the current 11 years, supporting the hub’s development and the planned Touquoy mine restart by December 2026.
While the program is well-funded and supported by grants, success hinges on drill results and geophysical interpretations yet to come. Access to some drill sites remains pending, and all exploration activities are subject to consultation with First Nations and local communities, which could influence timing and scope.
Bottom Line?
St Barbara’s aggressive exploration ramp-up in Nova Scotia could reshape its resource base, but the true impact will depend on upcoming drill results and regional study outcomes.
Questions in the middle?
- Will the expanded drilling program confirm significant extensions to known deposits near 15-Mile?
- How will the province-wide Meguma Terrane study influence target prioritisation and exploration strategy?
- What are the potential impacts of community consultations on exploration timelines and access?
