Using MinView to Explore NSW Geological Information
MinView allows anyone to visualise detailed geological information for NSW. Options include aerial photos, geological maps, geophysical data, mining leases, active and derelict mines, microfossils and more. These instructions will help you get started. 1. Go to the MinView home page: https://minview.geoscience.nsw.gov.au/
The home page looks like this:
2. Pick an area to explore. It helps if you add place names. View major place names and geology at the same time by clicking the blue bar ‘Add view’ and choosing ‘-> Apply’ for Seamless geology.
The result is a geological map with major locations, roads, rivers and surface geology:

3. We are going to zoom in on the area around Orange and Bathurst using the + symbol at the upper left of the map. Drag the map to centre it.
4. We will now explore an area with proven mineral resources and use geophysical imagery layers. 5. First, switch back to the satellite imagery. Anything of interest there? Those who know Cadia mine may be able to spot it.
6. To see geophysical data:
• Click the blue bar ‘Add layer’
• Scroll down to ‘Geophysical imagery’
• Click the down arrow to open up the menu

The screen should look like this:
7. High gravity readings can indicate metal deposits, so scroll down and click the blue + to display ‘isostatic gravity’ to see this view (with the layer selection window collapsed).
The big red area on the left looks interesting (high gravity), so we need to explore to see if it is likely to have metals. 8. Unclick (red x) Isostatic gravity and click the blue + to display ‘Total magnetic intensity’ to see this view (with the layer selection window collapsed).

When you compare the views, there is definitely something happening on the left of the screen, Southwest of Orange, but not so clear on the right side, south of Bathurst. 9. To see if anyone has decided to mine the area:
• Open your layers and scroll down to Mineral resources.
• Show the options (click down arrow) to see Operating mines.
• Click the down arrow and view the Metallic mines (click blue +).
You will see three mine sites when you collapse the menu (two are on top of each other).
You can click on the mine icon and then the Report to learn more. What is mined at Cadia Valley Operations? What is mined at the Golden Clad Mine?

10. See if there are any drill holes nearby that you could use to find information. Add another layer for Drilling, Minerals drillholes and choose All. You will find that these red areas have led to a lot of exploration.
11. If you want to get a firsthand look at the geology of a drill core, you can find out what cores are held at the Core library in Londonderry.
• Unclick all mineral drillholes.
• Scroll up to Core library
• Open the menu Physical core
• Choose “All drillholes”.
This view has a lot less drill cores, but these cores are available for analysis and we may be able to find a promising strike without having to pay for drilling. 12. Explore the available data. You will note that there have been many analyses around the old Golden Clad mine. You can view cores in National Virtual Core Library free of charge and see what minerals are in them.

Click on the dataset for one of the cores. Here is part of the photographic data from a core taken just southwest of the Golden Clad Mine.
If you click on the image, you will open a new window in which the detail of the tray is shown, including analyses of reflection that indicate the mineral composition of the rock. 13. Click the red box to ‘Remove all layers’. Now explore around your home by clicking the magnifying glass icon and typing in your address. To find out what is near your home, add a layer for Mineral resources, mineral occurrences. If you click on the ‘Mineral occurrences’ line, it will show you the legend so that you can
identify the local resources. What minerals are found near your home? (Zoom out if necessary.) How far away are these resources?

Which resources are found near Sydney?
Which resources are found near Parkes?
On the map of NSW below, mark the main areas with mineral sands.
