Anyone who has invested in junior miners knows what a tease Mother Nature can be.
A hot drill result will excite investors and seduce the market into thinking that a company has discovered the next bonanza. Then – far more often than not – further work shows the discovery to suffer from what geologist Brent Cook calls a fatal flaw: insufficient size, low ore grades or any number of other problems that ultimately render the find uneconomic to mine.
“The basic fact of mineral exploration is the odds of success are really, really low,” says Mr. Cook, co-author of the newsletter Exploration Insights.
Investors who are eager to tilt the odds in their favour may want to look at a different way of getting involved in the early stages of finding a mine. Firms known as prospect generators specialize in sniffing out promising grassroots prospects. Their goal is to partner with larger mining companies that can bear the financial brunt of testing these potential finds to identify the tiny percentage that turn out to be economic to mine. Both partners then share the bounty.
Invest in a handful of reputable prospect generators and you get a diversified portfolio of projects. “With six to 10 prospect generators, you can have exposure to 50 to 100 projects over several years which can dramatically increase your odds of success,” says Adrian Day, CEO of Adrian Day Asset Management and author of Investing in Resources.
Why don’t mining firms do the grassroots exploration work themselves? Many miners focus their exploration efforts on expanding around existing mines. Working with a prospect generator offers them a chance to preview a large range of possible targets in regions they may not know well and then invest in the best opportunities.
Ideally, “it’s a symbiotic relationship between a company whose core expertise is exploration feeding a company whose core expertise is mining,” says Paul van Eeden, president of privately held Cranberry Capital Inc. and a director of prospect generating firms Miranda Gold Corp. and Evrim Resources Corp.
The occasional bonanza can more than compensate for the long odds of success. After prospect generator Virginia Mines Inc. discovered the rich Éléonore deposit in Quebec, it was able to sell the deposit to giant Goldcorp Inc. in 2006 for $420-million (U.S.) worth of Goldcorp shares and a rich royalty.
Investing in prospect generators requires a different approach than putting money into a conventional junior explorer, says Mr. Cook, who invests in both types of companies. With conventional explorers, you need to assess the geology of a specific site, stay on top of every drill result and keep an eye out for problems.
“I spend all my time looking for the fatal flaw,” he says. “If you know 95 per cent of the time the stock is going to go down, you want to find that fatal flaw as soon as you can and get out before the crowd.”
When it comes to prospect generators, you aren’t betting on a particular find, but rather on the ability of the firm’s team of geologists to turn up a stream of interesting projects. Most prospect generators concentrate on “greenfields” opportunities away from existing mines. This is a high-risk endeavour, but because a prospect generator has to finance only the relatively inexpensive work of exploring and testing a site for drilling potential, it doesn’t chew up money at anywhere near the rate as the miner that does the drilling. If several projects fizzle, that need not be a disaster.
This allows average investors to adopt more of a buy-and-hold approach, Mr. Day says. Another attraction: Non-geologists can see how a prospect generator is doing simply by checking on how successful it has been in enlisting joint venture partners.
Those partners often include many of the world’s leading mining companies and their scrutiny of potential projects is rigorous, Mr. van Eeden says. “You have to persuade their geologists that they have to go get financing within their company for your project instead of taking their budget and spending it on their own projects.”
Project generator stocks offer less downside than conventional junior miners, while maintaining a good portion of the upside, Mr. Cook says. “Their bad isn’t that bad,” he explains. “If their partner drills a project and it turns out to be not that great, it didn’t cost these guys a dime.” On the other hand, if a project does well, the payoff can be sizable. “You’re not going to get a ten-bagger [a stock that goes up 10 times],” he says. “But I’ll take four three-baggers any day.”
Prospect generators typically have small teams of geologists who perform relatively low-cost geochemical, geophysical and geological tests to identify promising targets. The prospect generator may drill a few holes to test a concept, but generally looks for a well-funded partner to shoulder the big bucks of drilling.
If the project continues to yield encouraging drill results, the joint venture partner accumulates a hefty bill, but typically ends up with a 51- to 75-per-cent stake of the project, leaving the prospect generator with a minority stake. As the resource becomes better defined, the prospect generator looks for an opportune time to sell, typically to the mining company partner.
But doing this well is not easy. Few prospect generators are able to combine geological expertise with the business savvy needed to manage partner relationships, Mr. van Eeden says.
The accompanying table lists prospect generators recommended by Mr. Cook and Mr. Day. Do your own research before investing in any of them. (Disclosure: I own shares in several, as identified in the footnotes.) And don’t go overboard. A portfolio of prospects generates more shots at success, but prospect generators can explore for years without finding anything economic.
Mr. van Eeden says to only invest money you can afford to lose. “Just because you’re dealing with prospect generators doesn’t take the risk away. It’s still a risky business.”
