If you live in or around Vancouver, here is how to show your support for mining and show your support for your loved one.  Take them to the Britannia Mining Museum on Valentine’s day.  At this link you can read why, including:

  • Three-course fine dining meal with wine parings
  • See the buildings, gallery and underground mine
  • Transport to and from Squamish where can sleep it all off
  • Tickets at $220 a couple.

I am not getting free tickets for this.  Indeed I am not getting tickets, period.  I have been to the museum many times over the years, usually taking grandkids from lost Valentines.  I can testify that in recent years they have significantly updated the site and this event promises to be fun in a spectacular setting.  Let me know if it works out for you.

In the past, we have all done silly things at mines that constitute safety violations.  Here I record a drilling program I worked on in 1981 and 1982 at the then-proposed Greens Creek mine in Alaska.  I post with only minor edits what I found last weekend amongst some old papers in the attic.

I post this old incident here in the hope that others (over 65) will similarly write of their past mine safety blunders.  Maybe these stories will help the young to avoid repeats and make mining life safer and safer.  Here is the story.

Noranda are now exploring a rich new gold and silver deposit on Admiralty Island, ten minutes by seaplane from Juneau across Douglas Island and Gastineau Channel.  We proposed a conceptual design for the tailings impoundment and are now in our second summer of drilling and soils testing. 

For the last two weeks I have been on the Island organizing drilling, logging core, and supervising a geophysical exploration program.  I have a good bedrock contour map, a chosen dam axis which limits the depth of excavation to 20 m, soil samples are being tested in Boston for response to electro-osmosis and dynamic disturbance, our drilling rig is broken and I have time to write.  Most of what I set down is extracted and rearranged from notes I made during idle hours on the drill site.

We are drilling again. The frustrations of completing a hole, moving the rig by helicopter, and starting a new hole are over.  The helicopter was late, the drillers were forced to stand around doing nothing for hours, the gas drums leaked, the Allen key for the Shelby tubes was lost, the rig rope broke, water pipes leaked, the wrong hooks were put on, oil was needed in the machine, and the whole affair seemed chaos and disorder.  I do not think though that the move was better or worse than others I have seen.

The rig is roaring contentedly, churning through a firm, very plastic gray clay.  The sun is warm on my greasy khaki sweater (made in Poland.)  The morning chill is gone, today is the solstice and we will have light well onto midnight, and I feel pleasantly sleepy.  Pity I cannot lay down and snooze.  But soon the STP hammer will fall and expectantly we will watch and count its every blow.  I take the split spoon, break it open, and reveal the cool, gray earth—clay and silt from some distant glacial lake.

Jack Watkins is the driller.  He is fifty and onwards with a hoary beard and deep sonorous voice, a slow pace and a cigarette at every break in the drilling.  He wears yellow plastic pants, a wet cream cotton shirt, and a black baseball hat embossed with the red letters R&M. 

His helper is Larry, his stepson and half Indian.  Larry is nut brown with a round open face, cheeky and smiling.  His dark black air falls profusely in a wave to his shoulders.

Larry works hard; yet he lacks a flair for imitative.  He is quiet.  He seldom says anything and when he does he remarks only of food or the drill rig.  He is nineteen and tells me that he has a girl that he will marry in three months.  His younger brother has been in jail five of the last six months.  Jack says that at first when told by the police of his arrest he worried.  Now whenever the younger brother is arrested, he says: “You took him; you keep him.  At least I know where he is.”

Normally the helicopter collects us at six o’clock.  But that night it had not arrived by seven.  With a forty-five minute walk back to camp, we decided to brave the bush and the bears.  None of us had brought a gun.  Larry seemed to recall the general direction to the beach, and he took the lead.  We came on large, fresh bear prints just as we were about to enter the woods and leave the clear area of the muskeg.  Recall that Admiralty Island has the greatest concentration of bears in all Alaska.  We milled around rather stupidly, muttered a few trite words, and in a collective act of courage, walked into the woods.

Except for the usual luxurious green forest, we saw nothing until we reached the beach and the long vista down Hawk Inlet to the Cannery where we camp. 

Now two guns lie side by side next to our lunch packs, jackets, and the logs on which I profile the soil samples.  The first evening target practice was a disaster.  I hit nothing.  Then we noticed that the gun sights had been adjusted by someone with left-dominated vision.  This corrected, the next evening I came within two inches of bulls-eye.  That is good enough to get a bear, I reckon.

I carried the gun with me when Syd Hillis, the SRK review consultant, and I wondered around site.  However, I neglected to take a compass.  We got lost; a strange and frightening experience.  Oh, we had just moved south about 200 m from an old drill hole, sat and looked at a particular geomorphic feature, turned around and started back along the path through the trees.  Syd took the lead but veered too far to the left.  Confidently I took over and guided us to the right and the path through the dense growth and the drill pad.  The rig was humming in the distance to my front-right and I knew my general direction was correct. 

Then we stopped to look, for nothing was familiar, and all was quiet.  We noticed the rig had stopped and somehow things looked different.

“Do you know where you are?” Syd asked.  I did not.

Carefully assessing things we noted the rise of the right abutment to our left—the east and the sun in the north.  The only problems were that I was not sure if it were indeed the left or right abutment and whether the sun should be south, north, or somewhere else in the land where summer sun goes from three in the morning until midnight. 

A sort of quiet panic sets in.  Complete indecision reigns.  Alternatives are not viewed clearly and one feels like a gambler: whatever you do is as likely to be right as wrong, right or left.

We stood on the tree stumps and looked, discussed possibilities, blundered a bit, and finally I lead us down slope.  The creek was running in the wrong direction, at least it was opposite to what I expected.  Outwardly confident, inwardly shaken, I went upstream.  At last I espied the flags of seismic lines and then I knew where I was.  Syd did not believe me, and I don’t blame him.  Even now I am not sure where and how we did stray.

It was good to get back to the Cannery.  Since 1974 when the main factory burnt, the bunkhouses on piles out onto the beach have stood, barely used. Now I sit in my room with its gray-painted wooden floor, thin board walls and look down the inlet.  The boat houses, the dock, and a fishing barge lend interest to the foreground.  In the far distance are the snow-covered peaks of the hills on adjacent islands, andVancouveris three hours flying time south.  Perhaps next time I will write of those views.

 

More written in 2012, thirty years later.

That drill rig kept breaking down.  The drillers, Jack & Larry, grew more impatient and frustrated.  Their final revenge was when time came to remove the rig from site, for the drilling program was ended.  We all stood around watching as the helicopter lifted the rig for the last time to fly it back to Juneau.  Then, of a sudden, the cable snapped, the chains came loose, and the rig plunged from a dizzy height into the muskeg and sank below the surface.  We never recovered it.  So today there is an old drill rig below the Greens Creek tailings facility.

This must be every miners nightmare: contradicting opinions on the safety of your tailings facility.  At this link is a report that is not all that specific about the technical issues, but pretty clear about the debate.  One the negative side we read:

Environment Centre NT director Dr Stuart Blanch said the independent monitor project director Philip Mulvey told a December stakeholder meeting there was an “extreme risk” of bank failure of the tailings dam [at the McArthur River mine, Australia].   The October released monitor’s audit report for 2010 stated the tailings capacity needed to be increased by the start of the 2010-11 wet season.  It also said there was an extreme risk of acid caused by leaching, draining into Surprise Creek.  Dr Blanch said the Territory Government should require Xstrata to set up a fail-safe containment system for the existing tailings dam before it approves a much larger mine.

Conversely on the positive side, we read:

But Xstrata Zinc Australia chief operating officer Brian Hearne said the company had its own independent reports contradicting the findings.  He said the company commissioned report to analyse acid risks in conjunction with the independent monitor stated that there was no risk of a spill.   Further he said that annual safety audits verified the wall’s integrity, built to store 1 in 200 year, 2-month duration rains.

How about a discussion of this debate.  Some questions to debate:

  • What to do when there are conflicting expert opinions?
  • Is 200 years, 2 months a safe criterion or is this inadequate when precipitation seeks to be increasing?
  • Is wall integrity the only issue of safety–what about overtopping that is a bigger cause of tailings failure than most other single causes?
  • What is, or should be, a fail-safe containment system for a big tailings dam.  It this technically practical?

Here from Google Earth is an image of what I take to be the facility in question.  Not sure how long ago this was taken.  Tell us more if you know.

And if you want to read more on tailing facility failure go to the InfoMine Continuous Conference on the topic.

The journal of the scientists and engineers division of the National Groundwater Association, is called simply enough groundwater.  No capitals that I can find.  The contents are learned and often obtuse.  Here is the abstract of a paper Rationales Behind Irrationality of Decision Making in Groundwater Quality Management in the January-February 2012 issue.  It does not deal with mining, but the ideas and conclusions are too relevant to too many situations in mining to be passed-over lightly.

This issue paper presents how certain policies regarding management of groundwater quality lead to unexpected and undesirable results, despite being backed by seemingly reasonable assumptions.  This happened in part because the so-called reasonable decisions were not based on an integrative and quantitative methodology. 

The policies surveyed here are: (1) implementation of a program for aquifer restoration to pristine conditions followed, after failure, by leaving it to natural attenuation; (2) the “Forget About The Aquifer” (FATA) approach, while ignoring possible damage that contaminated groundwater can inflict on other environmental system; (3) groundwater recharge in municipal areas while neglecting the presence of contaminants in the unsaturated zone and conditions exerted by upper impervious surfaces; (4) the Soil Aquifer Treatment (SAT) practice considering aquifers to be “filters of infinite capacity”; and (5) focusing on well contamination vs. aquifer contamination to conveniently defer grappling with the problem of the aquifer as a whole.

Possible reasons for the failure of these seemingly rational policies are: (1) the characteristic times of processes associated with groundwater that are usually orders of magnitude greater than the residence times of decision makers in managerial positions; (2) proliferation of improperly trained “groundwater experts” or policymakers with sectoral agendas alongside legitimate differences of opinion among groundwater scientists; (3) the neglect of the cyclic nature of natural phenomena; and (4) ignoring future long-term cost because of immediate costs. 

We could all tell tales of similar situations and results.  But I refrain right now, as the lawyers are involved.  Maybe one day.

A wage is an hourly rate.  A salary is an annual amount.  Here is information about wages, in dollars per hour, for folk who work at what we think of as quarries & gravel pits.  Continue Reading »

Rummaging through old papers this weekend, I came across a short hand-written piece that I penned in 1982.  I repeat it here with no edits.  This piece is interesting in light of the muddle made by the Alberta ERCB in demanding an oil sand tailings strength of 10 kPa so that the deposit can be trafficked for reclamation.  10 kPa is simply not enough to support even puny equipment.  The ERCB could have avoided a great deal of fuss & bother if only they had consulted others.

Soon after the fall of the Berlin wall, we descended on Wismut, East Germany with proposals to help them cleanup the old uranium mines, mills, and tailings impoundments that the Russians left behind.  The large American consulting firm that I was working for at the time, believed that with our UMTRA Project experience, we were well-suited for the work.  So too did a small Canadian consulting company.  Continue Reading »

Is Sex Necessary?

Today was cold, mainly as a result of last night’s snow which left a wet slush on the sidewalks of the townhouse complex.  I trudged through the slush to dispose of garbage in the common shed from which it is collected at irregular intervals.   Lying in the shed was a yellowed copy of an old paperback with the provocative title Is Sex Necessary?

The quantity of information that is needed to make rationale mining investment decisions is immense.   It is near impossible to read all the daily emails or go to all the conferences and meetings on mining that have as their ultimate gold-goal the provision of advice to help you make profitable mining investment decisions.  Now there is one more source of information; and I venture that it is a good and useful one.
