I am told that yesterday’s posting was hard to read.  So rather than write tonight, let me simply post some pictures I took from a public road of tailings facilities closed by the Peruvian regulators.  Not sure how long the gabion baskets will last.

Words cannot capture a day of intense impressions.  Yet let me try. Go east of Lima into the hills (as I did today) and see this:

  • Tailings clinging to the steep hills in defiance of gravity.
  • A mine closed by the government to perfection.  They know what they are doing!
  • Filter-pressed tailings transported fifty kilometers up 1000 m elevation to a new disposal site — economically?

The news report today that caught my attention is this. Politicians say such strange things!

Argentina’s mining minister, Jorge Mayoral, surprised quite a few of the 300 executives present an annual luncheon last week, by calling its neighbouring Chile and Peru mining models “a failure.”

According to Mining Press (in Spanish), the official was especially critical of the other two countries openness to foreign investors. Mayoral said Argentina did not want mining in a Chilean or Peruvian way:

“We want mining our way, which means we want to favour domestic suppliers, local management, make sure jobs are taken by technical and professionals coming out of our universities, that respect for the environment is a priority, and most importantly, that all this is done in a safe matter,” he was quoted as saying.

Ironically, the minister also called on his Chilean peer, Aurora Williams, to expedite a decision on Barrick Gold’s Pascua Lama project, which has been halted since last year, after a number of defeats in local courts about water use and the impact on glaciers in the area. While later Barrick stopped construction of the $8.5 billion project as part of its debt-reduction and cost-cutting program, it is still facing major fines and a class action lawsuit because of it.

A report released by the government in March shows Argentina’s mining sector is expected to attract about $4 billion this year, with US and Indian companies reportedly interested in developing the nation’s copper and lithium.

“Call me Luke.”  Thus introduced, we sat down to talk about his career, his company, and mining copper. Luke is a civil engineering graduate of the University of British Columbia.  He spent the first five years working for consultants in the United States and British Columbia on tailings facilities.  “That way I learnt part of what makes a mine work,” he assured me, as the names of the mines slip easily from him:  Kennecott, Dome, Campbell.  (more…)

Yesterday I finished a three-day EduMine webcast on Mining Investment – Understand the Risks.  Today I took my own advice to heart and attended a presentation by Luquman Shaheen of Panoro Minerals Ltd on their projects in Peru.  Should I invest?  Should I advise you to invest?  Should we join Hudbay Minerals who own some seven percent of the company in the excitement of new prospects in a mining-potential-rich part of Peru?

In yesterday’s blog posting, I speculated on the potential for use by Californian quarries of recycled sewage water.  Today I read an abstract of a paper to be presented in Lima, Peru next year at the conference on Mine Water Solutions. (more…)

On the plane from Santiago to Dallas, I sat next to an Australian from Newcastle.  He told me that he was on a round-the-world trip to promote his product.  He explained that his company makes the wire ropes used on the big shovels so common in open-pit mining.  (more…)
