ConnectMining.com is a new (to me at least) website that defines itself thus: (more…)

Here is a link to a new newsletter on mining with an emphasis on Australia.  The editor is Johann A Robertson scion of consulting engineer and InfoMine man, Andy Robertson.  Johann has been in Australia for the past couple of months expanding the operations of InfoMine on that vast continent.  Now at his own initiative, he has founded the newsletter—one that we hope continues and grows in stature with time.

A very old friend, now prominent in Australian mining spent the weekend with me.  We drank expensive whiskey, which he paid for, and rode many miles on my bikes around Vancouver on a fine sunny fall day.  We recounted stories of the old days in South Africa as young & inexperienced engineers and how we solved problems by gut feel rather than knowledge and computer models.  (more…)

On a plane, somewhere between Santiago and Dallas, while enjoying food , drink, and Green Day on my iPod, I read in one of the five magazines that I regularly peruse, an article that said that business leaders who support Romney are not coming out in his support.  They think he will be good for the economy; but they do not like his, and the Republican’s, social policies.  Who but mittconception and his tribe believe that pregnancy, even by rape, is God’s will?  (more…)

This week again in Santiago, Chile.: exhausting meetings; deep & intense deliberations; keeping up with mining geniuses; writing reports of profound importance; trying to expedite significant decisions; and trying to make mining happen in large projects.  The issues are lack of power and the cost of water ($2.50 per cubic meter.)  The challenges are multiple models that seek to solve the same problem, yet produce vastly divergent results.  Add to that the diversity of the ore body, an absence of full quantification of variability, and the statistics of risk tolerance.  (more…)

Conferences like the recent Tailings & Mine Waste 2012 are often accompanied by a trade show.  At Tailings & Mine Waste there was a great hall with booths of almost every company I know of in the mining, and specifically, the tailings industry.  I wish I could list them all, for they deserve our support for supporting the conference.  (more…)

Risk is the product of probability and consequence.  In the long term, as time proceeds to infinity, the probability of an adverse event tends to one.  When seeking to control the risk of long-term tailings facility failure, there is little we can do about the probability of failure.  In the goodness of time it will occur.  All we can do today, is to seek to limit the consequences of failure, adverse performance, and unacceptable impact.

A 5.7 earthquake has just rattled the building here in Santiago where I sit.  This link tells us the magnitude, location, and depth—a real deep 95km. (more…)

Today I received this from Venmyn, a South African company that is the leader in mine valuation and NI 43-101s as applicable. (more…)
