Implementing photogrammetry into dynamic grade control workflows at the Waihi gold mine

Emerging technologies are a constant challenge to integrate into production geology workflows. The large volumes of data generated and the requirement for data to be analysed immediately can hinder technological advances.

Ore control processes at Waihi are now using new developments in the field of photogrammetry and grade control modelling to produce higher quality and improved geological interpretations. Add the ability to modify these interpretations immediately after data capture and the results are better geological models, with direct production benefits.
