I realise you are an expert in mining so your insights are interesting.
<snip for space>.
Yep, in 35 years working in mining & exploration in the USA, Canada, Africa, the Middle East and Oz (and just a brush with oil & gas), I've seen about 3 full cycles of boom/bust.#
Never driven a taxi though; started my own business 15 years ago and when things slow down, I revert to writing books.
# I missed out on the '70s nickel boom though - that would have been fun.
With mines, certainly they have environmental obligations, though it doesn't take a large team to manage the monitoring etc. required to discharge their obligations. Moreover, if an operation is put on cold storage, there are less impacts and accountability required; even less if they are in the middle of no where with little obligations to community.
The location of the mine is irrelevant; environmental obligations are statutory and on-going, regardless. Whether or not the mine is producing, or on care-and-maintenance, the monitoring and reporting is pretty much the same. Gotta show that the mine isn't affecting the environment beyond what the permits say. In a mine complete closure, the environmental dept goes berserk - all that rehab to do, and monitor, and report on in addition to the on-going monitoring and reporting on the mine waste dumps etc. There's usually a hefty environmental bond held by the govt agencies which is only released when the agency is satisfied, so there's an added incentive to do it all well.
Let me tell you, the last 5 years of a mine cash flow model has just one line item - 'Environment' :mrgreen:
But you are talking about environmental engineers - not sure I've ever worked with one of those. Ones I know and have worked with have all been of the 'bug counting' variety. I suspect the environmental engineers would cost a lot more than the bug counters, so yes, may be put off early on.
Actually I am the honorary bug-counter for the project in Canada I've been working on for the past 5 years
. Canadians have a surprisingly laissez-faire attitude to the environment. I, on behalf of the Australian board, had to go in and organise baseline environmental studies (AKA bug counting), fish monitoring (guess how!), dust plume and sound dispersal studies, groundwater monitoring, you name it. I know which side my bread is buttered!
I thought geos - or geochemists or geophysicists - would actually do pretty decent throughout most downturns. Exploration, testing sites and assaying for mine and block planning, planning or costing open cut versus underground mining... these would be persistent technical tasks even in downturns (mining companies trying to separate or realise which are their marginal grade operations and which are their better ones, plus better stockpile planning for processing purposes and improving recovery). So surprising to hear that geos are in trouble, too.
Geos/geochems/geophys/fieldies are the first to get it in the neck for 2 reasons. Greenfields exploration is definitely the first activity to get chopped - large $$ outlays, for no short (or even medium) term return. Its a short sighted policy, but ya gotta cut somewhere that's going conserve money with minimum affect on production. Pure exploration companies go into hibernation or discover technology.
In mines, there is usually ore defined for a few years. Lay off a geo or two and work the others harder! And those grade control issues you mention - yes, important, but just a few changes to the inputs into the algorithm and a new mine plan can be produced in less than a day.
I guess these days the geos don't drive taxis but rather become web designers. Banking is also a popular diversion. I went investment banking for 10 years, but not in a down turn - some-one's got to tell the bankers how to value that deep, black hole in the ground. But 10 years was all I could take. Not a nice 'environment'.
Oops ... sorry about the long post. My favourite subject, can't you tell!
