A bit of self promotion.  There is still time to sign up and join us next Tuesday, Wednesday, and Thursday mornings (PST) for the EduMine course on Mine Waste Management and Treatment.  See this link for details.

This is an entirely new course–none of the materials we will present have been presented before.  The reason this is new and important are the presenters:

Jack Caldwell will focus on the engineering side of water management, discussing available state-of-the-art technologies and appropriate management systems for advanced mine water management from design through closure, including a renewed focus on risk assessment and decision making. David Kratochvil and Patrick Littlejohn of BioteQ will address recent advances in processing and treating water for mine uses, mine reuse, and discharge.

In particular this is the first time that David and Patrick are presenting an EduMine webcast.   I have known them both for many years and have become more and more impressed by their knowledge, skills, and ability.  I just had to get them with me onto an EduMine course.  I know that what they present will be state-of-the art, practical, and relevant.

We will deal with the new ICMM guidelines on mine water management, on limiting water use on mines, on treating water to recycle water, and preparing water for discharge in accordance with more stringent regulations.  We will discuss the best papers of the past year in InfoMine and other conference on mine water management & treatment.  In short we aim to bring you up-to-date with the best, newest, and most practical approaches to making your mine use less water, use water wisely, and reduce the increasing cost of water and it use.

All three of us stand ready to talk with you about the course before the course if you like.  Contact me at jcaldwell@infomine.com and I will direct you as appropriate to David or Patrick.  In fact if you have special issues, join us, let us know of your specific interest, and we will address them in the course.

See you there.

On Saturday I succumbed and bought an electric bicycle.  It is marked Evo-Race and Easy Motion.  I got it from a small store in North Vancouver on Forrester Avenue for about half of what I paid for my five-year old Honda Civic when the lease ran out.  A bargain—the Honda, not the bike.

Yesterday I rode the new bike up the Lower Seymour Conservation Reserve road. Some fourteen kilometer uphill and the same downhill.  Those hitherto steep hills faded to nothing.  Put the bike in level five electric assist and up you go at far greater speed than is polite.  Then coming back downhill, I put it to level one assist and hit a high of 55 km/hr.  This speed, amazing to me, was not the electric assist.  For the assist cuts out at 39 km.hr.  Rather the speed is the result of long, steep downhill stretches and a bit of pedalling.

Today I rode into and back from town along the usual routes I take with my ordinary bicycles: the Cannondale Quick, the Trek roadbike, or the Trek cross country bike.  I prefer the Cannondale as it light and easy to maneuver.  You sit more or less upright and can see and weave in and out of traffic in the city streets and bike lanes.

But it is a whole different ride on the Evo.  I took me but 45 minutes to get home across the second narrows bridge; it normally take an hour and a quarter—half an hour more to drink!   The ride down to the SeaBus was not much different as it is all downhill.  But those steep hills, that get steeper each year, melted in the face of level five assist and a bit of pedalling–for you have to pedal otherwise the assist cuts out.

In spite of what I imagined, you still get a good workout on the electric bike.  It is heavy and needs human (arm and upper body) power to control.  You still have to pedal furiously to keep it moving in the lower gears and lower assist settings.  You still need to move those legs and breath fast to keep moving.  Faster than a normal bike, perhaps, but an equal physical workout over an hour and a half there and back.

So I am glad I stopped hesitating and at 68 gave into to a modern contraption–an electric bike.  If you are hesitating, getting old, and the hills are getting intolerably steep, go get an electric bike.  It is great and I will still ride the other bikes to keep in peak fitness.  Promise.

And in closing let us stop to sympathize with the Iranian blogger Farshid Fathi and the Saudi Arabian blogger Raif Badawi both of whom are sentenced to and have been flogged and imprisoned for blogging.  I have done in a secular sense what they did otherwise.  So now I blog poetry and electric bikes.  Makes you wonder?

It has been a tumultuous week of many events.   No blogging however. No topic caught my attention enough to spur the muse and misogynist.  So here a few stories of mining to entertain us and prompt the responsible journalist to attention. (more…)

As a US taxpayer I am at loss to understand how $1 million dollars can be sent to Peru to deal with illegal mining.  Here is a link to one report on the US taxpayer-funded largesse.  The report notes:

The U.S. Department of State awarded US$1 million to the Blacksmith Institute to work with Peru’s Ministry of Environment (Minam) to reduce the use of mercury and design remediation plans in Madre de Dios and Puno, it was announced today.

The United States believes it is crucial to support the Peruvian government strategy to combat illegal mining and reduce mercury use in artisanal and small-scale gold mining.

Where is the Tea Party when we need them?   Have they nothing to say about this blatant waste of money to support a lousy government unable to manage it own affairs?  The only explanation I can come up with is that somebody related to somebody or indebted to somebody has managed to arrange this and is being paid a considerable percentage of the funds.  Smells rank & corrupt to me.

Another sad story of underfunded mine closure.  According to this report, Yukon Zinc owes the territorial government $3 million in environmental security.  Now the company is bankrupt and also owing $646 million to hundreds of creditors. The tailings management system is described in a report at this link.  The system is described thus: (more…)

The Mining Association of Canada (MAC) has announced that they are convening a panel to ” review its tailings management requirements to ensure failures, such as the one registered at Imperial Metals’ Mount Polley open pit copper and gold mine, can be prevented.” (more…)
