Ethan in Adelaide Posted April 24 Share Posted April 24 Hi team, just found this on Geoview map near Laverton. I have had a look and there is no mines or old works logged nor old GML OR P OR PA etc. is this something natural or? kind regards, ethan Link to comment Share on other sites More sharing options...
phrunt Posted April 24 Share Posted April 24 a dip in the ground where water settles more causing it to be greener? Link to comment Share on other sites More sharing options...
Aureous Posted April 24 Share Posted April 24 Most likely a rehabbed drill site. All of the drill cuttings have been pushed aside with a dozer and the bags collected and dumped. Lots of these in the district. The discolorization is due to the drill cuttings being green such as diorite, serpentine or green shale. Often, Nickel deposits are in a green zone there I've noticed.

GotAU? Posted April 25 Share Posted April 25 As there aren’t very definitive and more recent egress tracks leading to those I think they may be natural- to determine wether they’re mineral outcrops or places where cows hang out will take boots on the ground or at least some better aerials than that image.

jasong Posted April 25 Share Posted April 25 See if you can get lidar imagery of the area. Prospect pits/spoil piles are easy to see on those, but they have the be high resolution imagery. In the US a lot of the lidar is still the low resolution and the prospects are harder/impossible to see on it, I'm not sure about Australia resolutions.

Hi I have checked the historical google earth map from 1984, appeared it has been there since then. @GotAU? Link to comment Share on other sites More sharing options...

Drilling of Nickel anomalies and structural drilling has been going on there since the early 1970's. A great deal of 'Mining the stockmarket' occurred during and after the Poseidon Nickel boom of the late 1960's. A great many minor Nickel anomalies were drilled and explored to give the appearance of actual work taking place. The region is full of these and the soil is usually discolored for many decades. 1 Link to comment Share on other sites More sharing options...

Then probably a drill site as Aureous says, or maybe weathering bedrock outcrops? It would help also if you can get a geologic map of the area. If you suspect a drill site, it wouldn’t hurt to take some samples and pan them out. Link to comment Share on other sites More sharing options...

See where red pins are 😁 1 Link to comment Share on other sites More sharing options...

Cainozoic is simply Tertiary alluvium or most likely a conglomerate deposit, These are often sources of well traveled minerals and commonly drilled to determine both for mine-able values and to obtain mineral samples to determine regional sources of said mineral. In this case, usually gold and/or Nickel. So, some prospectivity but nothing to 'pack your bags at once and go' sorta thing 😉 I see its at Wilga, East of Lake Carey. Many of us here on DP will recognize the name and know that the whole district has had many thousands of gold patches found over the past few decades. With the right detector setup, Lake Carey itself is always worth trying and has produced 1000's of ounces of gold in the past. 1 Link to comment Share on other sites More sharing options...
