This study introduced a smart-glass-based augmented-reality framework integrated with RTK-GNSS positioning for real-time bench-level ore-grade visualization in open-pit mining. By converting conventional block-model grades into lightweight polygon representations and synchronizing them with high-precision spatial positioning, the system enables intuitive in-situ interpretation of ore-waste boundaries directly within the operator’s field of view. Experimental observations demonstrated stable spatial alignment, acceptable visualization latency for walkingspeed inspection, and improved cumulative positioning accuracy through RTK correction and sensor fusion, with corrected AR alignment maintained within 0.46 m. The results confirm that the integration of RTK-anchored positioning, polygon-based geological abstraction, and wearable augmented-reality visualization can deliver spatially coherent and operationally meaningful bench-level representation of ore-grade information. Such capability enhances situational awareness and interpretability during grade-control activities and illustrates the practical potential of immersive digital visualization within emerging digital mining environments. Current validation focused on pedestrian traversal as a controlled test environment. The MINARVIS production platform is intended for in-vehicle deployment, with the augmentedreality rendering pipeline designed for use within excavator, drill, and loader cabin environments. The present evaluation establishes the technical feasibility of the core approach within a research prototype context. Extended field deployment and quantitative performance validation under production conditions are currently in progress as part of the MINARVIS commercial pilot program, with site trials expected at an operational open-pit mine in Western Australia. 5. ACKNOWLEDGEMENT The MINARVIS spatial correction architecture, including its infrastructure-free positioning methodology and augmented reality integration framework, is the subject of a provisional patent application currently pending with IP Australia.
