- The discovery history and geology of the Proterozoic, sediment hosted, red-bed style Cattle Grid copper deposit in South Australia as told by the geologist who made it happen: David Tonkin.
This is the first video in the Eureka Moments series that will look at the critical decisions made and processes followed in the discovery of new mineral deposits.

I'm a diamond driller with a hobbyist level interest in geology, loving this content. Love to hear about how diamond drilling contributed to the success here.
20m of loose sand cover is a challenge for any drilling technique, and there are plenty of drill rods in the walls of the Cattle Grid pit to prove it!
@@GeologyUpSkill fortunately with advances made since the 60s, the challenge is much mitigated with new technique and technology! I'm a 3rd generation driller and my grandfather started drilling back in 1962 so I learned the old school ways and got to learn the new school methods!
The best way to learn!
Another good one, Nick. I knew nothing of this deposit, so it was fascinating. I reckon a few comments in the last minute or so of the video perfectly sum up the best approach to exploration: 1. Don't allow yourself to be a slave to (or dictated by) the perceived geological model; 2. Take what you know plus what you can see and follow the "trail or breadcrumbs", combined with allowing your instincts to lead the way, and 3. Don't be afraid to think outside the box, even if it goes against the corporate direction or directives. Cheers, mate.
Excellent interview and great insights to the world of geology and minerals. Well done.
Thanks very much. Hope to do more on other deposits soon.
The King is back, appreciate the effort 👍
Thanks very much. Editing this one was a marathon effort, particularly the animations. Davinci Resolve is a staggeringly powerful piece of software, but the learning curve is pretty steep!
thank you very much for sharing your experience. It's a great lesson about discovery. The key: Understanding the controls of mineralisation and geology.💪
Thanks very much. And full credit also to David Tonkin for presenting the story so well in front of the camera. I hope it encourages more geologists to share their knowledge like this for future generations of explorers.
As a south Australian I’ve a,ways found it astounding that the deserts of SA were once permafrost with massive aeolian dune fields.
Geologists get an entirely different perspective on climate change.
Thanks again!! Regards form Chile!!
Great I'm deciding to do my Ph.D. on SSC deposits and gathering more data from operating and explored deposits is the key. thanks
Cattlegrid is quite unique in style, but definitely in the SSC basket. It would be a good example to study.
@@GeologyUpSkill would you please introduce me to a researcher on the SSC in Australia? as a foreign coworker?
Fantastic Geological Mindfood! 👍
Super excellent.
Thanks. I need some more volunteers in front of the camera!
Any chance your putting together a breccia specific video? Highlighting textures & mineralization, particularly tourmaline breccia in a Cu-Au Porphyry environment? Thanks in advance!
I haven't worked directly on any projects of that type, but it would be a very interesting subject for an interview style video like this one. Any volunteers out there with the right experience? In the mean time, check out the websites for Chakana Copper and Turmalina. They have some superb examples and detailed descriptions of the tourmaline type.
amazing deposit
Indeed it is. Remarkable that it is still the only one of significant size that has been discovered in Australia.
Have the snake guards ever outright protected you from an attempted bite? I use a different brand and so far I have yet to experience them being put to the test. I'd like to keep it that way, but I'm just curious if you've experienced otherwise?
Fortunately I'm the same as you on snakes, but they have protected me from countless puncture wounds from broken sticks hidden in the grass and tick bites that itch for weeks (see my video on ticks and how to avoid them)
@@GeologyUpSkill I can second that! While I don't encounter as many ticks being in the desert as you may have, they have absolutely protected me from multiple punctures from sticks and spiny plants the desert is so affectionately known for! 😅
I'll check out your video for ticks!
I’m sure there is copper out there everywhere, you just need a corporation to build a mining operation, but where hasn’t been explored?
Rule#20! czcams.com/video/_OTqSlFAk1Y/video.html
There are dozens of reasons why explorers fail to find orebodies that are sticking out of the ground. czcams.com/video/0XFbT_tLcug/video.html
@@GeologyUpSkill I agree it’s out there to be found. The supply and demand will eventually make these companies span further and further into the wilderness to find easy to get, or profitable mining works. Can you tell me a mine that I could run myself to actually make a decent living? If I found the deposit myself?
I’m serious I want to buy claims and make a living off the land. Is it even possible?
DIY is extremely difficult to make money. Much better to option your claims to a company and charge option fees and retain a small interest.
