A new prospectivity mapping technique has been developed that is invaluable for gold exploration in several gold rich regions of the Yilgarn Craton. Parametric Fingerprint Analysis allows you to put your tenements into perspective and to assess which kinds of deposit you can expect to discover.

2. WHAT ARE PARAMETRIC FINGERPRINT MAPS?
• A new tool for mineral exploration
• Developed from a wealth of geological data including GSWA maps and the
Minedex database
• Based on computationally intensive statistical analysis of known gold
deposits and how they relate to the surrounding geology
• They assess a region’s mineralisation potential
• They can identify which deposits occur in ground geologically similar to your
tenement
• The can be used to rank tenements in order of mineralisation favourability
• They can be used to assess directionality in prospectivity in an area
• Discover natural extensions to mineralisation

3. EXAMPLE
PARAMETRIC
FINGERPRINT
For the Kalgoorlie Terrane, 14
geological parameters have
been identified that are spatially
related to gold mineralisation.
These geological parameters
have been represented in map
from and normalised for the
purposes of measuring a
deposit’s fingerprint.
We are working in 14 dimensional
space!

Baden Powell Gold Deposit
Vector values are represented as the number of
standard deviations from the mean of each input layer
V1 anticlinal fold hinge abundance (-.44)
V2 fault abundance (0.36)
V3 lithological contact abundance (1.55)
V4 low rheological contrast contact abundance (2.16)
V5 fault proximity (-0.77)
V6 high rheological contrast contact abundance (-0.88)
V7 lithological contact proximity (-0.73)
V8 low rheological contrast contact proximity (-0.79)
V9 strike of proximal anticlinal fold hinge (-0.39)
V10 strike of proximal fault (-1.01)
V11 strike of proximal lithological contact (-0.43)
V12 lithological variety within 2km radius (2.29)
V13 lithological variety within 5km radius (1.46)
V14 change in lithological variety (0.01)

fingerprint map for the Kalgoorlie
Terrane.
Parametric fingerprint map is for
the deposit called Baden Powell
and is based on 14 input Layers.
Warm colours indicate locations
parametrically similar to the
location of the reference gold
deposit.

5. EXAMPLE 0.5%
SIMILARITY MAP
This map is based on the previous
and shows the 0.5% of the
ground that is parametrically
most similar to the fingerprint
location.
It allows for a quick analysis of a
regions importance based on a
single known deposit.

6. FACTS ABOUT YILGARN GOLD
• Gold mineralisation is the result of craton-wide events
• Any host rock can be mineralised
• Some better than others
• Almost any structure can be mineralised
• Some better than others
• Statistically based empirical prospectivity mapping techniques can be
used to construct maps with a definitive predictive capability
• Based on outcrop data and prospectivity analysis, only around 40% of gold deposits
have been discovered.
• Many undiscovered gold deposits will lie under shallow cover in
geologically similar environments to known gold deposits

7. IT’S LOGICAL!
• An area geologically similar to one that contains known mineralisation
will be more likely to host mineralisation itself
• Our atlases of Parametric Fingerprint Maps can be used to measure
key geological parameters and to see how well they apply in your area.
• Over 950 sites of known gold mineralisation in the Kalgoorlie Terrane
• We ‘fingerprint’ each of these in relation to statistically proven
mineralisation-related parameters
• We see how well these fingerprints compare to the geology of your
area as a series of easy-to-read maps

8. USES OF FINGERPRINT ANALYSIS
• Evaluate your tenement
• Do other deposits share similar geology to your tenement?
• If so, which deposits are these?
• Are they significant deposits?
• Considering acquiring another tenement
• Fingerprint analysis provides a quick evaluation of a tenement without the need to
visit the location
• Fingerprint analysis can help you determine the direction to expand your attention
• Do you have several tenements that you need to winnow down?
• Fingerprint analysis, in conjunction with traditional methods, can help you in the
decision making process

9. WE PROVIDE
• A map that shows the number of relevant
Minedex records that occupy
parametrically similar ground to your
tenement.
• Maps that show the individual
contribution of each component
fingerprint
• PDF ‘atlas’ of results
• Additionally we can provide the data for your
tenement in GeoTiff format for easy
importation into a GIS
• Report of the analysis

10. AN EXAMPLE
• Client interested in acquiring a prospecting
license that boarders on their mining lease
• Fingerprint analysis of mining lease (to the right)
shows that between 1 and 18 unique Minedex
records (out of 963 or ~2%) are located in
parametrically similar ground.
• The northern part of their tenement has the
greater number of fingerprint matches
• This part of the tenement can be considered more
prospective
• The prospecting license to the west has a poor
number of matches relative to the mining lease
• Probably not a good acquisition*
• Instead focus on analysis / acquisition of ground to the
north.
As these are based on public-domain data you should, of course, not rely solely on the
fingerprint analysis results in making any decision. The results of this analysis needs to be taken in
context with other decision making tools. Please read the disclaimer that comes with the atlases
of parametric fingerprint maps about the use of these data.

11. COVERAGE
• We have produced atlases of gold deposit parametric fingerprint maps
for the following regions
• Kalgoorlie Terrane (1:250K)
• Leonora 1:250K map sheet
• Laverton 1:250K map sheet
• If your tenement or area of investigation falls within one of these map
sheets then we can conduct a fingerprint analysis for you.
• We are currently assessing the Murchison province at 1:500K and this
will be available late 2013 / early 2014
