Panel 1 : Geological modelling software: Development and limitations

Technology is a critical driving force for improving the quality of modelling, dealing with skill shortages and reducing the risk for investment and development of projects.  Looking at parallel industries, software is a driving force that has the potential to deliver rapid change. As an industry how do we continue to push change?

Commercial products are limited in their rate of change due to the need to maintain and support applications and existing customer workflows. On the other hand, coding and open-source applications are allowing skilled geologists to customise and build innovative new workflows. But where does the balance lie between using vs creating and extending software?

What is the next frontier for geology software and what impact will this have on mineral resource estimation?

Panel: The future of geostatistics

Geostatistics originated in the 1950s and 1960s as an evolution of classical statistics to address prediction problems in mining, forestry, and meteorology. In natural systems, such as mineral deposits, neighbouring measurement points tend to have similar values rather than random fluctuations. Geostatistics provides a more precise mathematical framework for describing this relationship compared to traditional methods, resulting in improved predictions for individual points, as well as areas and volumes.

By the late 1980s, many of the methods currently in use had been developed or were proposed in theory, although some required advances in computer technology to fully realize their potential. In the 1990s, geostatistical methods became more widely adopted in the mining industry.

Today, geostatistics is widely used in fields such as mining, environmental monitoring, agriculture, spatial statistics (GIS), and data science. Linear models are commonly employed, and advances in computer technology have made it possible to use simulations and multiple scenario options more frequently.

Looking forward, this panel discussion will explore current developments in geostatistics and how they can improve the accuracy of predictions and risk evaluations.

Panel: Domaining: Do we still need it?

The concept of estimation domains has long been a fundamental part of mineral resource estimation. The ‘domain’ is a primary grouping of the data – thus it affects every aspect of the estimate.  Use different domains and the outcome can be markedly different. 

Like many foundations, however, the meaning of ‘domain’ is not well constrained and is often context specific. This leads to misunderstanding and confusion when the same term is used in different ways in different but closely related specialities, for example, structural geology, economic geology and resource estimation. Many of the ideas behind estimation domains are a function of the estimation method (e.g., kriging) or arise from historical, manual (pre-computer) approaches to modelling. 

 With the lessons from the last 50 years, the advent of new technologies and the changing nature of our economic mineral deposits, are estimation domains still relevant or are there alternatives?
