Talking Points

Recent interactions between the hosts and their guests.

EP 160 | Part 7 of 7: Case Study - Applying Localised Conditional Simulation at Bullabulling
Q: Why did you choose localized conditional simulation over conventional methods for this project, and what difference did it make in practice?
We chose LCS because ordinary kriging tends to smooth grades and can misestimate both grade and tonnage. LCS captures grade variability and uncertainty at a block scale, highlights high-grade domains, and aligns better with how the deposit behaves, ultimately changing the outcomes and risk assessment without changing the basic modeling workflow.
EP 160 | Part 7 of 7: Case Study - Applying Localised Conditional Simulation at Bullabulling
Q: So to start with, can you give us a brief overview of the Bullabulling Project and the deposit type you're dealing with?
Bullabulling is a large, open, low-grade gold system near Koolgaardie, WA, with a resource of about 4.5 million ounces at around 1 g/t. It consists of many mineralized domains with variable grade, presenting challenges for traditional estimation methods due to significant local grade variability.
EP 153: The Genesis of Australia's Nickel Industry
Q: Okay, so Ian, what is the significance of the date 28th January 1966, which is just over 60 years ago now?
It marks the day KD1 intersected nickel sulfides at Cambalda, effectively launching the Australian nickel industry by proving there was a mineable nickel deposit and setting off a rapid chain of exploration, investment, and development across multiple sites in Western Australia.
Ep 141: Mineable Shape Optimisation (MSO) - where geology, cost, and design intersect
Q: Can you provide a mini workflow for the MSO?
The workflow begins with understanding the block model and economic assessments, ensuring all assumptions and constraints are in place for effective use of MSO.
Ep 141: Mineable Shape Optimisation (MSO) - where geology, cost, and design intersect
Q: What common pitfalls should we care about when using the MSO tool?
Common pitfalls include not comparing MSO output to actual results and expecting every ore body to behave the same way, overlooking the unique parameters required for each case.
