The Tyee, a local Vancouver e-newspaper with a decidedly liberal bent today published an article on peer review of Mt Polley.  David Ball is the author of the piece.  I think he did a good job in balancing the opinions. I admit to being hopelessly prejudiced in this opinion.  For if you read David’s piece, you will note that he quotes me and Nordie Morgenstern.  David called me a while ago and asked how I would have gone about preventing Mt Polley and how I would go about preventing future Mt Polleys.  We talked long about peer review.  To his credit he checked what I was telling him by contacting Nordie Morgenstern.  He also established that there is currently only one tailings facility in BC that has a peer review board.

This picture and the others in this posting were taken by me at Knotsberry Farm in California.
A great place to visit and enjoy a terrifying ride along the raging river of insanity.

If you seek a thorough and intelligent analysis of dealing with uranium mill sites (and particularly the tailings facility) take a look at the following–it is an amazingly comprehensive document–and should be required reading for all involved in mine management, regardless of whether the mine is uranium, copper, gold, or something else.

The PowerPoints of presentations from the Tailings and Mine Waste Conference in Keystone are now available.  At least the PowerPoints of those authors who gave permission.  See this link.

They are all interesting, so choose those that interest you.

I recommend the presentation by Steve Vick who is one of the reviewers of the failure of the Mt Polley tailings facility.  He assures me that he compiled the presentation before the failure and there is no connection between what he says in his presentation and what he might say in the panel findings.

The presentation by Franco Oboni touches on the same topics as Vick’s but takes a different approach.

I particularly like the presentation by Craig Benson on the hydrologic performance of final covers.  He concludes that we can and have constructed covers to last for at least 1,000 years.

I am sure there is much to say about these presentations and indeed the other presentations, so please comment.

A million here.  A million there.  Who cares?  It is just taxpayer money spent by your local government providing the services you expect to be provided at no cost!  Just learnt that HATCH has been awarded a contract by the BC Ministry of Energy and Mines (MEM) to review the independent reviews of BC tailings dams that MEM ordered pursuant to the failure of Mt Polley.

Here is information I received as a comment on a recent blog posting:

California is an anomaly from the perspective that it is only one of 5 or 6 states or territories that do not recognize mining as an engineering discipline; along with Guam, Hawaii, Delaware and a couple of others. The need for being registered is driven primarily by the State Boards. There are several places in the industry where signatures are required: on 10K reports for certification of reserves. This requires a “qualified person” and since there are 20 states that don’t recognize geologists as a profession, then the role may be defined as engineering in some cases. There are a plethora of state and federal mining permits requiring a PE signature. Underground seals must be constructed and signed off by a PE. Roof Control and Ventilation plans and many environmental permits require signatures. As I said, California is one of the exceptions and I really don’t understand why mining is ignored when mining was at the core of the state’s formation. I will say that the lack of recognition by the State has caused some confusion regarding liability and accountability.

It is all too easy to be beguiled by the propaganda of mining protestors. Maybe they are correct when they protest mines & mining in their area. But now we have an example of a protest, not in the mining arena, that proves the fallacious motives & reasoning of mining protestors. I refer to the recent protests against performance by the MET opera of the opera The Death of KlinghofferAt this link we have an intelligent analysis of the protests and the opera by that august magazine, the New Yorker.  You may care nothing for opera, and care less about a modern American opera by the foremost modern American opera composer, John Adams.  But I urge you to read this posting by the New Yorker and judge it as an example of mindless protest against a worthy undertaking.

Had a chance today to look through the proceedings of the upcoming conference Heap Leach Solutions 2014 scheduled in Lima, Peru for November 10 through the 13th, 2014. The paper that caught my eye and caused me to stop and read it is titled Leach Pad Cost Benchmarking.  The authors are Mark E. Smith and Denys Parra of Anddes Asociados SAC, Peru.  Two famous folk in the field of heap leach pads.  You will have to wait for the proceedings to be published to get a copy, but for now let me quote from the paper. Here is the paper abstract: (more…)
