Today I was criticized for failing to clearly set out the project objectives. Damn me, I know what we are setting out to do. “But the rest of us do not,” was the reply. And so I wrote out the project objectives in deliberate detail. And that set me writing the rest of this posting. [...]

Bellavista, Costa Rica and the persistence of mining. How to fix mine failures?
Posted in consulting, environmental, Gold, Heap leach, Investing & Finance, Latin America, People, Reclamation, Uncategorized, tagged Bellavista, Costa Rica, failure, heap leach pad, peter tagliamonte on April 18, 2011 | 4 Comments »
Greed, speed, and engineering carelessness all led to the massive failure of the Bellavista heap leach pad in Costa Rica. The failure of the pad led to the closure of the mine and bankruptcy of the company. The massive failure is now the subject a major law suite: all parties ever involved are suing and being sued.

Good Mining Advertizing? Anglo angles watery appeals.
Posted in Community relations, Heap leach, Reclamation, Tailings, Waste Rock, tagged advert, Anglo American, ladies hard hats, Pebble Mine, porn, water on November 18, 2010 | 3 Comments »

This week, EduMine posted a new course that I wrote. As is the title of this posting, the new course is called Geotechnical Engineering for Mine GeoWaste Facilities. I was prompted to write the course when I was called on to explain to a client who is not a geotechnical engineer what is involved in geotechnical engineering. This [...]
