Exploration geologists are often faced with a situation where they are asked to find the Holy Grail with a small budget. In the past, potential deposits are often missed due to a lack of funding or poor targeting techniques.
In this episode of Coffee with Samso, I speak to Dr Ryan Noble who is the principal research scientist for CSIRO. He works for the Mineral Resource business unit.
Understanding weathering profile key to mineral exploration
The CSIRO has been providing solutions to the mineral exploration industry for many decades. The whole concept of understanding the weathering profile or regolith is the key to many discoveries.
Ryan shares with us the concept of using bore water to vector into potential mineralisation geology.
