Clap! The sound a big volume of mining proceedings made when it landed on my desk this morning. Dropped from on high, this volume is the collection of technical papers from an International Symposium on closure of uranium mines at Wismut in Germany. If you haven’t heard of Wismut, then I suggest you get a [...]

Introduction Today I went to HR Block and had my taxes calculated. It is a disaster: I owe lots and the total taxes I paid is more than the average Canadian salary.

On the 31st floor of a Vancouver downtown hotel this afternoon, we attended an open house arranged by Paterson and Cooke. They presented the opening of their newVancouver office.

The Wisconsin legislature has just posted a proposed new law on mining in the state. The full document is available at this link. At 191 pages it is not a short read; but it is a must-read.
