Gold Maps  -  How to Use Geological Maps and Systems to Target Gold in WA

The key takeaway from using Geological Maps is how to use them as "Gold Maps" to target gold  in WA. i.e. To show the location and types of Geology where gold in likely to be found in WA. (Or anywhere in the world  for that matter!)

Here are 4 basic criteria you use to find gold in an area More detailed in the "Where to Find Gold In WA." pages but broadly they are;

1. By Association

  • Understand Rock Types that Gold occurs, eg Quartz, Ironstone.
  • Look at Local Deposits and rock types. 
  • 1:250000 and 1:10000 Map Explanatory Notes.

Mineral or gold deposits in the local area tells you: 

  • The types of rocks to look for, and 
  • The geological structure it occurs in the  Geological Map area.

Regolith (The rocks and soil between the bedrock and Surface) - Sediments Over Archean Rocks (Archean and Proterozoic Rock Types are the key Geological Age periods of formation of Primary Gold.) also host secondary gold formations

2. By Proximity   

  • Where gold has been found before. 
  • Old Gold Mines and Mining areas.
  • Scraping detecting and dryblowing areas.
  • Abandoned Mines.

3. Analysis of Geological Structure

  • Use Geological Maps (Tengraph Web or GeoMap) as gold maps,
  • Sills, Dykes, faults, contact zones, quartz veins
  • Primary Archean rocks
  • Secondary gold deposit types such as Laterite, Salt lakes, calcretes. Can be formed after erosion and chemical deposition in situ on top of  or downhill, downslope or downstream from Primary Deposits.
  • Hidden paleo channels. Ancient stream beds or waterways that have been covered by sediments.

4. Soil Sampling and testing to find Hidden Deposits.

  • Historical soil sampling and drilling is available from WAMEX (WA Mines Exploration data can be shown and interrogated on Geoviewer, Tengraph Web and GeoMap) 
  • Minedex shows where minerals occurrences, mines, types of mines, drill holes, outcrops are. They can be viewed on Geoviewer, Tengraph Web and GeoMap)

The geologic map patterns in an area enable you to create your own understanding of gold maps i.e. where gold is likely to occur in the locality where you are prospecting.

Explanatory Notes - Tell Y0u Where the Gold is Found

In the page on Geological Maps Online and how to get them there is also a link to "Explanatory Notes for 1:100000 or 1:250000 maps" these notes actually tell you in the Economic Geology Section what types of Geology minerals occur in the area of the Map.

That is Mighty Helpful!


Geology and Gold in Tengraph Web and Using GeoMap as Gold Maps

Geology and gold locations can be identified on the freely downloadable PDF Geology maps described in the "Free Geological Maps" page or:

  • in Tengraph Web which is an online program or, 
  • GeoMap which is an offline program that you use in the field. 

It can also be used to identify the gold mines and occurrences and thus are gold maps as well as identifying the geology where gold occurs in an area.

How to use Tengraph web and GeoMap is more fully described in out training site www.geomap-training-wa.com which also has a series of Free training on the prospecting rules in WA and How to Locate Gold 

The Free training Course conists of the following Elements:

1.0 The 4 Methods to Target Gold in WA

2.0 Rules and Laws for Gold Prospecting In West Australia

3.0 How to Access and Login to Tengraph WEB

4.0 An Overview of GeoMap

Historical Gold Mines on GeoMap

Geoviewer Can Be Used to Create Gold Maps

Geoviewer is an online program provided by the Department of Mines (DMIRS) and you can create gold maps using selected Geology Maps and information about gold mines taken from Minedex as in the graphic. 

We will provide more information and training about Geoviewer shortly but information is available on the DMIRS Website at GeoViewer

Gold Maps Using Goldtracker

There are programs and apps that analyse all the technical data that you need to know to target a specific location to find gold in WA.

Goldtracker is one that analyses the potential of gold deposits for every graticular block in WA. A graticular block is 1 minute by 1 minute of latitude and longitude.

There are approximately 1.09 million (1,090,080) graticular blocks in WA

Goldtracker analyses and calculates a score based on a complex algorithm using:

  • Geological Structure and Gold Deposit types (13 Types).
  • Lithology and Chemical elements within each graticule e.g. Au, As, Se Fe, Mo, Ag, Bi (Above background).
  • Economic Geology.
  • Alluvial occurrences, workings, Historical Data,.
  •  Technical evaluation of likelihood of occurrences  by Dr Watling and Ray Hammond.

There are 19000 graticular blocks that have a score of 80 or above in Western Australia. 

A Score of 80 is considered to be of  good potential for gold deposits in any block.

Goldtracker is available here at www.goldtracker.net.au

There  are many ways to create your own gold maps to search for gold and with them you can laser focus on the areas of WA that you want to prospect for gold.
