Optimism. noun

1. a person who tends to be hopeful and confident about the future or the success of something. “only an eternal optimist could expect success”

Bananas

A bit like a 99-year-old man with heart failure buying green bananas, exploration geologists are optimists. We have to be. A bad case of pessimism would be a huge impediment to building a geological career that survives past the initial 5-minute interview with the VP Exploration.

“Can I have a job please? I don’t think we’ll ever find anything, but I’ll give it a go if you pay me.”

“WTF? No. No. No. Who let you in? Piss off. I don’t need a depressed hat stand on my team. Please don’t slam the door.”

A wellness website  I picked at random for its daft name, has this to say about Optimism. “(it) is a mental attitude characterized by hope and confidence in success and a positive future. Optimists … expect good things to happen….. Optimistic attitudes are linked to a number of benefits, including better coping skills, lower stress levels, better physical health, and higher persistence when pursuing goals.”  To which I’d add “poverty” if your optimism is directed at the junior mining sector, although strictly speaking that’s not really a benefit.

Optimism in the junior mining sector comes in many different flavours, from the plucky perma-cheerful investor relations professional -the ones with a fixed whiter-than-white smile as all around them turns to market shitness- to the self-proclaimed geological genius building the next great model of mineral deposit formation based on gut, tea leaves and thumb sucking. They’ve all convinced themselves that everything’s going to be just great for investors so stick with them. Please.

It’s Egregious, Whatever That Means.

IR and marketing people are perhaps guilty of the most egregious levels of optimism in our business. When did you ever meet one at a conference who was negative or down on the company? Shit drill results? “Don’t worry. The hole we’re drilling now is a scorcher, but you didn’t hear that from me.” Flooded mine? “‘Tis but a trickle. We’re buying more pumps. They’ll be there Monday, sucking up that water like beer.” When it’s really going badly they’ll tell you in hushed tones to double down because adding more shit to your existing pile of shit is sure to end well, as we all know.

But I digress. The truth of the matter is, geologists have to be optimistic because nearly all of of us spend the bulk of our careers NOT finding anything -in my case close to 30 years in exploration, sadly without involvement in a world class discovery. Most of us will be involved in smaller discoveries; half a million ounces of gold here or 10-million ounces of silver there, but deep down we all want to find the Big Kahuna and be loved and envied by our poorer, luckless peers. As one buy-side friend wrote to me: “Our whole sector is driven by optimism. Exploration geologists are the extraverted cowboys who only need to make a correct call ONCE in their career to be regarded (by peers and investors) as a hero.”

Optimists, Damned Optimists & The Deluded

Geo-optimists fall into 2 broad camps -optimists and blind optimists. Members of the first species base their optimism on a certain level of knowledge of their subject; an educated optimism where they believe they have a better than average chance of success given the team’s experience.

The blind optimists are crucial to our poor success rate as explorationists. They’re the geologists who begin to rely on their optimism and very little else. Yes, their read of the geologic evolution of a mineralized system really is better than anyone else’s, and their unique insights will sniff out the big one and make everyone rich. They’re much more dangerous to your investment account because they haven’t a clue what they’re doing, and they don’t realise they’re clueless, but they still believe they’ll succeed at finding a world class mine. (The worst case of this I ever saw was a project in Washington. It sat under a mature cherry orchard and could only be accessed by a hypothetical 13,000 ft long incline, but that’s a story for a different piece.)

The trick to industry survival for both camps is being able to translate that optimism, whatever the flavour, into a pitch that can persuade the money guys that the geologists actually know what they’re talking about. 

As Brent Cook will tell you (if you’re able to track him down between pedicures and beach volleyball -oh the joys of semi-retired life) at least two thirds of companies -and hence geologists- are simply trying to up their luck in the discovery game by recycling tired old projects or ideas; optimism based on trying to cut corners. It’s easier than risking everything on the application of actual science. Experience suggests that for these companies luck is still such an important component of the discovery process that very few real discoveries come from their efforts – perhaps 1 in 10 of the good finds that you read about. Brent sees them as basically bullshit plays -a whole leaky raft of explorecos temporarily claiming they’re geniuses, when in fact it was just plain dumb luck that paid for the ski chalet in Whistler.

As an investor, the best time to give any company your hard-earned savings to chase a dream is probably when the optimism has been tempered by gobs of cynicism experience and they’re better able to recognize the fatal flaws, whilst knowing not to give up too easily.

The Majors and Optimism

The major miners (sorry) have a slightly different take on optimism.

Owen, my-ex boss who ran Anglo American’s exploration efforts for a number of years, told me that he’s never subscribed to the need for optimism in exploration and sees little or no room for it. Bear in mind this opinion comes from the big budget camp where it’s perhaps easier to divorce yourself from dreaming of the pot at the end of the rainbow. An $80-million annual exploration budget buys you a lot of chances to get lucky.

Money trees aside, his take is pretty simple. Since the big company needs to find new or replacement resources for reasons of survival or growth, you really only have 3 options. You can buy your way to success, acquiring companies or projects, or you can joint venture into early-stage projects. Alternatively, you can decide as a company to conduct your own exploration. A combination of all of the above is wisest to manage the inherent risks and reduce reliance on optimism. At that point, it’s hello science, and fuck optimism, because who needs it? Exploration becomes a hard-headed game of hiring the best staff; making the best area selection based on the best models and using the best search technology to look for stuff. Good discipline and decision making are vital, and you have to know when to stop if it ain’t working.

Undeterred, I suggested to him that a degree of optimism (and a ton of lick spittle grovelling) was still needed for those vital budget pitches to the Board. To which he replied that the Board simply needed the comfort of knowing that he and his team were efficient managers, not starry-eyed optimists thumb sucking over a map. Hence, he always tried to convey to the executive that 1) the observed geology was compatible with a good model assembled by the best people, and 2) if it looked like a project was a loser, it would be dropped or farmed out as soon as possible before any more money was wasted.

Optimistic Engineering

At the engineering stage, optimism is everywhere. Best project ever! Can’t wait for the PFS results! Cash flow! But engineers are as guilty of blind optimism as geologists. Remember, there’s never been a failed mine without a positive engineering study, right? Consultant engineers are usually a bit more circumspect, presumably because they get sued from time to time when mines go tits up and the raging, red-faced lenders lose their shirts.

It’s a little-known fact (apparently) that 75% of published economic studies will show that their project is in the lowest quartile of operating costs. A fabulous example of optimism, lying or mass delusion, or all 3. Hardly surprising really. Would you want to publish a Friday morning news release showing that your project is going to be one of the highest cost mines in the world? Yes? No? Anyone? But logically, the remaining 25% of projects must be in the er.. upper 3 quartiles. Hmm… 25% = 75%… right, I see. Something’s wrong with this math.

An alternative way of looking at it, quoted to me by another friend (yes I have more than 1) is that only 1 in 20 mining projects exceed the feasibility study forecasts, and 50% do not. One major company found a systematic 4-6% optimistic bias in the internal rate of return for a dozen or so projects it had modelled and built. All of the mines underperformed their cash flow models by roughly that amount. Optimism be damned. The fact is something’s generally wrong with the models. (Hint, the real world is complicated and has a way of messing with engineering assumptions.)

Most investors will only see the inherent engineering optimism at the news release stage: internal rate of return, net present value, capital cost and the discount rate used are pretty much all they ever take on board. The rest is engineering guff but it’s also where the serious optimism comes in to play. Power costs, labour rates, tax rates, grinding indices and a whole lot more – it all flows into an unwieldy spreadsheet model that pukes out the NPV/IRR/Capex summary; numbers we all love and cherish and quote as the sterling silver truth, until the project fails. No optimism here then, move along please…

Ounces Schmounces

The voodoo we call resource estimation takes optimism to a different level and is the cause of many a failed mine. I’ve never tried to fully understand the discipline. To me, statistics is akin to thermodynamics. No matter how many times I sit in a classroom or read Statistics for Dummies, it’s in one ear and rather swiftly out the other, dragging my tiny allocation of math brain cells with it.

If you’ve ever had the misfortune of talking to a resource estimation geologist, it all goes off the rails within 10 seconds of them opening their mouths. I may as well be listening to an evangelical preacher speaking in tongues. It’s like I opened the wrong door and ended up in 4th year statistics crossed with a “How Not To” scientific writing course, taught by a socially maladjusted, beardy, optimistic savant. (Sorry Mike, not you obvs.)

I can grasp averages, medians and the odd standard deviation or two but beyond that I’m useless. I have no choice but to be optimistic and assume that the practitioner of the dark art knows what they’re doing. In fact, I can sum up my understanding of geostats in 2 short sentences: a) when comparing 2 numbers, if their ratio is about 1 that means something possibly important; b) big numbers are generally better than small ones. That’s all you need to know to bluff your optimistic way through a board presentation.

In practice, all of this means that if you give the same set of sample data to 1,000 resource geologists, you’ll get 1,000 different optimistic resource estimates. Management is always convinced that they’ll get the huge tonnages and priapic grades that the investor wants. But to deliver them, the consulting resource person has to dip into an increasingly weird bag of statistical mumbo jumbo. Take Kriging. According to Wikipedia it is:

“Kriging or Gaussian process regression is a method of interpolation for which the interpolated values are modeled by a Gaussian process governed by prior covariances, as opposed to a piecewise-polynomial spline chosen to optimize smoothness of the fitted values.”

Funny enough, one of the quoted disadvantages of Kriging is “Not easy to comprehend”.

By the time all of the optimistic resource cases have been compounded, iterated and checked by the independent peer reviewer, there is absolutely no room for manoeuvre. Iteration becomes a way of life – can we tweak this and try again? We can? Great! By the end, the resource relies on so many convoluted factors; just one has to fail and you’re lumbered with a project that is by now too big to fail or save.

And Finally, Newsletter Writers

Most newsletter writers are smart, and they’re immensely optimistic most of the time. The latest hot story gets written up in glowing terms, but the rest become yesterday’s news, cast callously aside into the exploreco compost bin with only worms for company. Some writers visit projects. Most will speak to company management at some point, hopefully. And some take nice photos so you can see your company’s team in action. They write thrilling stories about helicopter rides and bears and nuggets and being there to watch as glittery, gold-engorged core slides smugly out of the drill pipes. And then they charge you a fat monthly fee for all that optimism, so little wonder it’s all going to be fine. They want your $500 next year. Yes, you at the back, they’re paid to be optimistic.

Enough Optimism Already

Anyways, that’s a few collected cynical thoughts on optimism in our humble business. You may agree or thing I’m completely barking. Whatever. But when you come face to face with it, just remember, somewhere there’s an investor (very probably more than one) who lost their shirt because they blindly trusted an over optimistic team of mining professionals. So be hard nosed. Ask the tough questions, and make sure you peel back the thick, blubbery layer of optimism that we all carry around with us until you get to the real story, warts and all.

What’s your take on optimism? Let me know.
