2018 went in a flash and here we are in 2019! To open the new year, we have a thought-provoking editorial from Peter McCarthy, an article on autonomous haulage in OP mines, and much more. Enjoy!

The ages of human development – stone, bronze, iron and maybe silicon – are defined by the geological, mining and metallurgical skills people developed. We work constantly to improve our technologies for the benefit of this society and that of future generations. We are part of a great global industry.
It is scary to look back and find a quarter of a century has passed since I graduated. However, during that time, I have ridden a camel in the Sudan, worked on the deepest mine in the world, driven in a tank across the steppes of Russia, tracked gorillas in Uganda, travelled to more countries than I would have ever dreamed possible, and met and married my true love and life partner.
Often the first budget item to be cut in times of austerity is exploration drilling. We will not go into the wisdom or consequences of this decision, but rather look at a means to optimize the money available for ongoing drilling. Most geologists who have had to do drill hole layouts will have come up with any number of tools or process automations through scripts or macros that help them design a reasonable drill plan in an acceptable time frame. One such approach is described in this article.
Although autonomous vehicles have been under development for decades, their productive use in mining is relatively new. As the technology becomes more refined and accessible, it is now more commonplace for new mines, and those with sufficient remaining mine life to consider running an Autonomous Haulage System (AHS).
Geometallurgy may be defined as the integration of geological, geotechnical, mining, metallurgical, environmental, and economic information to provide a platform to increase the net present value of a deposit.
In the late 1970s to early 1980s Ordinary Kriging (OK) became the block grade estimation method of choice. This was mainly due to it being an unbiased estimation method that attempts to minimize the extension (estimation) variance of the estimate.
The widely publicised reduction in mining productivity both on a volume and cost basis during the mining boom, coupled with the lower commodity prices and reduced investor confidence in recent years, resulted in most miners focussing...
On 19 July 2018, AMC Consultants' Kobus Potgieter, Business Improvement Manager, presented the last installment of Austmine's "Optimising the Mining Fleet Webinar Series" focusing on the optimized fleet in action. Kobus was joined by Stephen Williams, Managing Director, Concerto Analytics in a panel discussion on the topic.
