One of the miracles of the free-market system is that when one person sells a share, there is another who is buying.  Who are the current buyers when all are seemingly selling? (more…)

The following just in from Venmyn Deloitte on reworking of old South African slimes dams or tailings facilities to use the more modern term.  All the old slimes dams around the area I grew up are gone.  The biggest loss is that big pile of yellow sand down which we would slide on corrugated cardboard boxes.  The pile was so full of uranium and gold that it was one of the first to go.  I hate to think what our radioactive exposure was as kids.  I can report no ill after-effects either from the radioactivity or from the mercury my father brought home for us to play with on the bedroom floor.  And we knew not what a seatbelt was in those heady days of vast exposure to danger.  (more…)

The golden rule of investing in a junior mining company is to ask and satisfactorily answer the question: who owns & runs the company?  In reality, investors go for juniors because their story is simple; the time-line to profit short; and there is something exotic & mysterious about their ore body.

The news is that the area around the Grand Canyon is off-limits to uranium mining for the next 20 years.

The Obama administration has banned new mining near the Grand Canyon, an area known to be rich in high-grade uranium ore reserves, the Associated Press reported. (more…)

To end the work-week, here is the knottiest problem I faced this week.  Maybe the readers of this blog can help solve the problem!  The issue: how to design a heap leach pad in a cold climate? (more…)

If you tour by Google Maps that part of South Africa where I grew up (mainly the East Rand around Brakpan and Springs) you will not see the many slimes dams that I knew and played around.  They are long since gone—reworked for gold and uranium and consolidated into a mega-slimes dam that I recall is called ERGO.

Here is a picture of a mining disaster waiting to happen.  This is a mine in Australia that is shut down because too much rain has filled their tailings impoundment and they appear to have no facilities to treat water hence to release it.  (more…)
