Spent time setting up sessions for the upcoming conference on paste and thickened tailings in 2013. Along the way, I checked out recent web additions on the topic. Here is what I wrote as a result–I post as the links may be helpful. (more…)

The following is an “article” that I repeat as is from a recent ACG newsletter. Andy Robertson of InfoMine and Robertson GeoConsultants wrote this. The “article” is at its simplest an announcement of an upcoming conference. But at its most complex this is a scary story of potential dragons let loose on the world to scare the populace into non-mining. Here is what he wrote: (more…)
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 T. Fitton) for putting that insightful paper together. (more…)

The answer will not come for many months, yet the arguments in today’s hearing before the U.S. Supreme Court are worth revisiting as they are significant to mining and environmental protection alike. And to those who revel in dictionary distinctions—like Scrabble players.
The highest court in the land has chosen to hear the issue of whether the Kensington gold mine in Alaska may put their tailings into Lower Slate Lake, effectively filling it in time, or whether they should turn the tailings to paste and put them above-grade just like they do at the Greens Creek Mine not that far away.
In practice, the court will not decide this practical issue. Instead the court will delve into far “higher” matters. Keep in mind the Supreme Court only takes on cases involving constitutional and interpretation-of-law issues. And in this case the issue is the meaning and intent of the 1972 Clean Water Act. Basically the question the court is asked to determine is whether tailings are “fill” or alternatively “discharge” in terms of the act.
