I am in Guatemala and at the Tahoe Resources Escobal Silver Mine. I have previously noted that I and my daughter are the engineers who designed and now give advice on the operation of the filter-pressed tailings stack. Much credit must also go to Flor de Maria Gonzalez and Sergio Aycinena of Geosimsa who are the engineers of record in Guatemala. We have worked closely with them these past four years and both have proven sound partners. Particularly Flor who as a young woman has made her mark by her excellence in a male-dominated Guatemalan mining environment. (more…)

This evening I watched the Mariinsky version of Prokofiev’s Romeo & Juliet.  This is the only ballet I like.  Mostly because of the music.  And, I suspect, because once I could recite the entire Shakespeare play.  (I was Friar Lawrence in the  high school production.)  And now in the ballet I can hear the words of every emotion.

This posting is a favor for someone I admire.  She seeks a job in mining and well deserves one. This evening I went to her farewell party from the company she is leaving.  She is leaving because the downturn in the mining industry means the company has to cut. (more…)

Here is the outfall of the Pebble Mine and Mt Polley Mine debacles.  A report on the Seabridge Gold’s KSM Mine in BC.  The report is authored by Salmon Beyond Borders, a coalition of Alaska Native tribal members, commercial, sport and subsistence fishermen, and other groups, in consultation with Earthworks.  The press release is at this link.  The full report is at this link.  Here from the press release on the five key risks associated with the mine: (more…)

Here is information about a new, to me, on-line magazine about mining.  The information I received that alterted me to this magazine notes as follows: (more…)

Please take a look at the photo-essay at this link before reading the rest of this posting.  The photo-essay is of work done to get the Bingham Canyon Mine going after the very big slide they had a while ago.  It is heartening to see the effort and success.  I hope it puts you in a good mood, at least a good enough mood to deal with the rest of this posting. I do not know whether to be amused or angry about the new site Yes to Life, No to Mining.  At one level it is ludicrous.  At another level it is infuriating.  As the announcement says: (more…)

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.
