Everyday Drill Hole Spacing Analysis | Jane Levett Snowden Optiro | Geology Symposium 2022 | APAC

Описание: Jane Levett, Principal Consultant - Snowden Optiro delivered her presentation with the title "Everyday Drill Hole Spacing Analysis" as part of the Geology Symposium 2022 in Perth hosted by Datamine Software.

Drill Hole Spacing Analysis (DHSA) is a set of geostatistical processes that assess estimation quality for a given actual or planned drill spacing:
🔵 Inform drill programme requirements from early-stage resource development to grade control.
🔵 Supports Mineral Resource Classification.

Jane Levett is an Associate Principal Consultant with Snowden Optiro, specialising in geological modelling and resource estimation. After graduating from UWA Jane has worked across many levels of the exploration and mining industry; from helicopter stream sediment sampling in the Northern Territory, pit wall mapping in New South Wales, resource development with Father Christmas in Finland, and plenty of time in Western Australia’s Goldfields.
Jane loves the challenge of ensuring geology sits front and centre in the resource estimation process and enjoys a hearty JORC debate. She currently lives in Albany, which guarantees a healthy work/life balance.
