See this link for details. This is an entirely new course–none of the materials we will present have been presented before. The reason […]

I am working on a new EduMine course on Cover. It will probably be a year or so before it is available. SO here is some interesting information I compiled yesterday. Undoubtedly the best way to control erosion on sideslope covers is to place a layer of durable rock. We perfected the design procedures on […]
On Saturday I succumbed and bought an electric bicycle. It is marked Evo-Race and Easy Motion. I got it from a small store in North Vancouver on Forrester Avenue for about half of what I paid for my five-year old Honda Civic when the lease ran out. A bargain—the Honda, not the bike. Yesterday I […]
The city was built on Cambrian rifts, boot-sucking mud, a rush to stake alliances. Now it’s birch, white pine, and alder creaking, a low, flat tailings pond where nothing thrives. Cat’s cradle of a radio tower the only hint that the human hive once buzzed, air-drilling its way from darkness to darkness. Like trees […]
Here is a challenge written up in a recent comment on a previous blog posting: I would love to see someone write a paper on the merits of a wet tailings pond. Today’s lovechild seems to be the filtered tailing concept but let’s hear some kudos for a properly designed wet tailings pond. It gives […]
Journalists (and bloggers) have discovered that spills are big news. There is always the element of failure, of human ineptitude, environmental impact, and an aggrieved local ready to state that all future headaches will be attributed to the spill. The most recent i a spill of radioactive fluids at the Ranger Mine in Australia. Here is part […]
Today was the first of three sessions of the EduMine webcast on heap leaching. We continue tomorrow and Wednesday. The webcast is well attended with people from as far away as the Congo and Brazil and as close as Burnaby, BC just east of Vancouver. If you are not attending, but are interested, there is […]
It costs between $1 and $40 a ton to build, operate, and close a mine tailings facility. That is as specific as I was able to be when answering a question today in response to an enquiry from Australia. There is a surprising paucity of data out there on the cost of tailings management. We […]
Yesterday I finished a three-day EduMine webcast on Mining Investment – Understand the Risks. Today I took my own advice to heart and attended a presentation by Luquman Shaheen of Panoro Minerals Ltd on their projects in Peru. Should I invest? Should I advise you to invest? Should we join Hudbay Minerals who own some seven percent of the […]
