Modern Mining May 2021 cover

Editor’s take: In this edition of Modern Mining, the editor discusses how gold miners have significantly shifted their exploration focus in recent years, favouring increased mine-site exploration at the expense of grassroots exploration.

Gold companies at both the top tier and junior level have become more cautious with their dollars, shifting their focus to lower-risk opportunities such as brownfield projects – those with previous capital invested in development and an established resource base.

The projects that investors find most attractive are those with clearly defined mineral resources and strong potential for becoming economically viable mines – the hallmarks of a quality brownfield project. In addition to providing cost savings, developing a brownfield property with existing resources or proven production potential is a much quicker path to returns.

Zest WEG launches IE4 electric motors in SAZest WEG launches IE4 electric motors in SA

As electric motors consume more than half the electricity generated around the world, it stands to reason that the energy-efficiency of these electrical loads affects not just the generation and distribution of electrical power, but also every aspect of industry. Modern Mining approached Zest WEG to learn more about the recently-launched IE4 motor and its improved energy-efficiency.

Championing digital solutions for 40 years and countingChampioning digital solutions for 40 years and counting

While mining companies have been considering for several years how digital transformation might alter the future of work, COVID-19 has accelerated this imperative. Gideon Slabbert, Maptek’s GM for Africa, discusses how mines in Africa are leveraging Maptek’s 40 years of championing digital solutions to meet the changing requirements of the industry in every mining stage, from exploration to operation.

Electric motors efficiency in focusElectric motors: efficiency in focus

While the electric motor is famous as the ‘workhorse of industry’, it is notorious for its energy appetite. Ironically, it is also applied in mining and industry’s most energy-intensive applications. In this feature, we look at the various motor, drive and gearbox ranges available from three suppliers, as well as at their efficiencies and advantages.
