Key Questions

Geochemistry

Geology GeophysicsMineral System

From Turnbull et al, 2018

What are Targets?

Defined as:• Areas of highest mineral potential• Best combination of predictive variables that

map the mineral system

Used to:• Focus exploration• Acquire new ground• Guide land planning and management• Plan drilling

Lithium pprb reclassified. 10 highest; 1 lowest post

probability

Lithium pprb grid (from model)

How are Targets Created?

1. Post probability of producing mines.

2. Specifying a percentage reduction of the study area.

3. Using natural breaks in the post probability values.

Cut-off methods

Attributing Targets with Model Data

Approximately 486 Lithium targets have been identified in the Taupo Volcanic Zone

Ranked by maximum and mean post probability

How are Targets Ranked?

• Model Name, year and type• Commodity• Mineralisation style• Country• Datum/Projection• Unit Cell• Success Rate• Conditional Dependence• Geochemical data (drill, rock, stream and

soil sample numbers, max assays)• Geology – lithology and age• Faults• Geophysical surveys• Tenement status• Ownership information• Cadastral and cultural data (proximity to

urban areas...) • Environmental restrictions
