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
