Talking Points

Recent interactions between the hosts and their guests.

The Fallacy of the Deep with Mark Arundell
Q: What assumptions in the industry are you challenging with the fallacy of the deep idea?
The idea that deeper drilling will automatically uncover the next big discovery, and the tendency to focus on deep targets due to the perceived value of higher-risk, higher-reward outcomes, while often ignoring the abundant value in shallower, well-supported targets and the need for robust data integration across disciplines.
The Rocks Meet Wall Street with Dave Lawie & Sam Scher
Q: What fundamental misunderstanding do financiers have about mining projects?
Financiers often treat resource models as fixed truths without accounting for the underlying geological processes, metallurgical realities, and processing constraints that can drastically change a project's economics.
From Evidence to Origin: Solving Mysteries with Isoscapes with Gabe Bowen
Q: Could you walk us through why oxygen, hydrogen, and strontium are commonly used to investigate geographic origin, or if there are other systematics that you're using?
Oxygen and hydrogen reflect the water cycle and climate signals, giving broad geographic gradients that can distinguish large regions. Strontium reflects underlying geology and bedrock, offering a complementary, more local constraint. Together they provide a powerful two-layer approach to narrowing down origins, with other isotopes like sulfur providing additional context in coastal or dietary scenarios.
From Evidence to Origin: Solving Mysteries with Isoscapes with Gabe Bowen
Q: Starting with the basics, could you explain what forensic isotope geochemistry is and what kinds of problems it's going to help solve?
Forensic isotope geochemistry translates isotopic signals from body tissues and materials into geographic or life-history information by using isotopes that record where a person has been or what they have consumed. It involves measuring isotopes in tissues, comparing them to reference maps (isoscapes), and assessing how different isotopes together constrain possible origins and movements.
Fit-for-Purpose Geochemistry and Fewer Bad Programs with Simon Bolster
Q: What does fit for purpose mean for you in practice, and where are explorers wasting money on assays that they don't need?
Fit for purpose means employing analytical techniques suited to the project's stage, assessing costs versus the need for high accuracy in early exploration stages.
