Assmang Khumani stockpile report

Khumani Mine Stockpile Report

A stockpile treatment for dust control and erosion prevention was conducted at ASSMANG Khumani Iron Ore Mine, whereby two adjacent stockpiles were documented, one was treated with a surface application of EBS Soil Stabilizer, while the other was left untreated. After three months 169 tonnes of material was lost from the untreated stockpile, no measurable material was lost from the treated areas, and in fact, vegetation had grown.

Full details of the independent monitoring including weather and wind conditions are available upon request in a compiled report which included three years of monitoring. Despite recommended maintenance applications every 18 months, no maintenance whatsoever has been done and the surface of the treated stockpile remains stabilized after 5 years while allowing vegetation to grow and providing dust control.
