I think the business section of the paper is consistently the most interesting; there is always some article which catches your eye. Today’s point of interest has a mining basis which relates to one of the major Northwest Territories diamond mines, Diavik. In short, Rio Tinto is looking to sell its stake in the mine [...]

With the Paste 2012 conference on mine tailings just a few weeks away in Sun City, I’ve pinched this title from a question posed at the 2008 conference in the paper Surface disposal of paste and thickened tailings – A brief history and current confronting issues. So thank you to the authors (M. Williams, K. Seddon, and [...]

The old adage “a picture is worth a thousand words” comes to mind when you look at the above photos. I was talking to a colleague about his trip to Timmins, Ontario for an Undergraduate Geological Engineering field trip to visit the old gold and base metal mines. I too had to share a few [...]

Integral to any new mine or expansion of a mine is the preparation of an Environmental Impact Assessment (EIA). If you seek to significantly expand the mine’s tailings, waste rock, or heap leach facilities, you may have to prepare a new or supplemental EIA.

Occasionally he would sing in an opera—what a thrill to see and hear him live. I vaguely recall that in the program notes, there were news pieces [...]
