Open Source AI and Junior Mineral Exploration
The modern-day geologist deals with large amounts of data: remote sensing data (satellite image, airborne geophysics, drone surveys), traditional geochemical, lithological and structural data. Advancements in computer science allowed the creation of artificial...

Understanding When Costs Associated with Overburden and Waste Removal are Capital Expenditures
Most open-cast mines require the removal of overburden and waste material to access the underlying orebody. This activity is known as ‘stripping’. By their nature, all open pits become narrower with depth, and consequently the volume of waste to be stripped is largest...

Navigating the ESG Landscape Part 2 – Responsible Mining
In a previous article published in June, 2020 (link), we set out key elements of the Environmental, Social and Governance (ESG) landscape, and how Micon can support mining companies at all phases and all scales to engage with sustainable approaches to addressing ESG...

Fast, Detailed and Practical Estimation of External Dilution for Open Pits
Micon has successfully evaluated the effect of minimum mining dimensions on operational dilution for an open pit mine, narrow-vein deposit. This study involved generating and analyzing 24 different minimum mining dimension scenarios. The expected operational dilution...

Top 10 Tips for Mineral Resource Estimation
Every mineral deposit is unique and requires a large number of items to consider when conducting a Mineral Resource Estimate (MRE) with some items more important than others. While Micon’s Competent/Qualified Persons may approach and conduct an MRE from a variety of...

Improve the Economics of Your Orebody by Ensuring it is Developed at its Optimum Production Rate
Micon recently completed a very successful scoping-level trade-off study to determine the optimum rate of production of a mineral deposit based upon orebody configuration, types of plant feed available, recovery options, infrastructure requirements, capital, and...
