Geology and Resource Model
Structural Controls on Gold Mineralization
Big Bear Gold Mine mineralization occurs within steeply dipping shear zones that channeled auriferous fluids from deep basement sources. Structural intersection points, combined with alteration halos, define high-grade shoots that justify the current resource confidence.
Drilling and Grade Control
Resource confidence rests on a blend of diamond drilling, downhole sensing, and 3D geological modeling. Grade variability is managed through focused infill drilling, allowing optimized pit shell design and minimal dilution during mining.
Mining Methods and Processing Flowsheet
Open-Pit and Selective Stoping
The operation predominantly uses open-pit mining with bench scales calibrated to equipment footprint. Selective stoping in higher-grade sectors reduces waste dilution and improves overall economics.
Conveyance and Leach Circuit Efficiency
Ore is crushed onsite and conveyed to the processing plant, where automated CIL circuits maximize gold recovery. Real-time grade tracking enables dynamic reagent dosing and consistent elution performance.
Operational Performance and Development Timeline
Construction and Commissioning
Current development activities focus on infrastructure, tailings management, and water control. Phased commissioning reduces risk and allows performance optimization before reaching steady state production.
Production Outlook and Cost Profile
Mine plans target all-in sustaining costs near established benchmarks, with upside from by-product credits and improved recovery rates. Production ramp-up aligns with contract marketing windows to optimize realized prices.
Environmental, Social, and Governance Considerations
Water Management and Land Rehabilitation
Water recycling loops and sediment controls protect downstream ecosystems. Progressive rehabilitation plans integrate native species and post-closure land use objectives, supported by independent monitoring.
Community Engagement and Indigenous Relations
Regular consultation with neighboring communities and Indigenous groups shapes local hiring, procurement, and training initiatives. Benefit-sharing frameworks aim to deliver lasting socio-economic opportunities aligned with regional priorities.
