1/x🧵
Most of remaining global #copper "yet to find" resources are estimated to be in sedimentary copper deposits.
Major sedimentary copper deposits occur on 170km lithosphere thickness boundary🌎👀
Nature likes order 📏
Why does it happen?
How can you use it as an investor?
2/x
Below paper summarised for non geos 👇
I read it so you do not have to.
3/x Before we dive in, you need to know what is "lithosphere" .
Part of crust and upper mantle - the harder outer shell of planet earth.
Thickness can vary from few kms to 400km depending on the place on earth.
4/x Also what are sedimentary copper deposits?
They form in rift basins as metal rich fluids circulate and come in contact with reducing rocks (shales, evaporates) they precipitate often large tonnage and high grade deposits of Cu, Zn-Pb.
5/x So let's look now at this 170km lithosphere thickness that appears to be important control. 🧐
6/x Globally, sedimentary deposits of Cu, Zn-Pb occur within 200km corridor surrounding 170km thick lithosphere contour.
Map of Australia below shows the contour representing 170km thick lithosphere (dashed line).
White colours c. 170km thick lithosphere. Check colour bar.
7/x Notice how the sedimentary deposits follow that dashed line and the white contour!
Especially the big deposits.
8/x
This rule applies to
95% Cu and 90% Zn-Pb deposits that are sediment hosted.
This eleminates some land for exploration!
9/x Okay, so there are exceptions...
All >10 Mt total metal contained sediment-hosted deposits are located along this boundary.
In my rule book, I am interested in Tier 1 deposits ✅
10/x So how can you use it as an investor?
10/x
The map with white contour of 170km shown on global scale is below. Quite remarkable occurrence of major sedimentary deposits of Cu, Zn-Pb.
Add it to your investment checklist or exploration tool kit ✅
If this was helpful please comment below ⬇️
If you are explorers and you already have it in your tool kit let us know ⬇️
I will add explanation on "why" this 170km thickness may be important during the weekend.

1/x Geophysics is a powerful tool in mineral exploration, but many investors and geologists struggle to interpret its results.
🧵Here's a simplified explanation of how it works:
2/x Geophysics is the only tool that allows us to see below the surface of the Earth. With seismic and tomography methods, we can peer tens to hundreds of kilometers deep.
Check out the example of tomography imaging below 😲.
3/x In mineral exploration, higher-resolution methods are required. Magnetics, gravity, electro-magnetics, and IP are some of the most commonly used techniques - you've probably seen them all in junior companies NSRs.
But what do they measure? And how can we use them?
Over the last years, we have actively speculated in #exploration sector.
Our approach has changed over time.
One of our strategies is to participate early on in discoveries.
🧵👇Tips on how to do it below.
Step #1: Stay up to date with exploration results announcements EVERY day.
For us #ASX and #TSX takes 10-20 min per day.
Success here comes down to:
• Know what you look for e.g. 20m @ 3% Cu
• Do not get distracted by noise
• You get faster over time
• Automate 😍
Step #1 cont.: Why EVERY day?
We missed the good announcements before. Most of the days nothing happens, but you do not want to miss the 200% move.
1/6 Most of the new #discovery announcements and good first holes ends up as a minor discovery.
How to spot significant discoveries as an investor?
2/6 Three steps to follow🪜:
1) Study significant discoveries 2) Study the failed discoveries 2) Learn the essentials of geology
Let's dig in.
3/6 Do the following:
• Select commodity of interest e.g. #copper#nickel#uranium#gold
• Study top discoveries made in the last years
• Look at announcements (grades, footprint, structures, geophysical anomalies etc.)
• Put it into a system
