Part Two: The Fundamentals (1)
Exploration plays tend to be heavily focused on geological theory, specialized
valuation techniques, and map studies.
First we need to understand the basic geological theory that has revolutionized
the Cortez Trend. Exploration is about playing Sherlock Holmes with geological
clues to make an intelligent bet about the size of potential deposits and the
probability that they will become economic. In order to intelligently put the
clues together, one must begin to grasp geological system concepts and the
analytical processes utilized by competent geologists to identify exploration
targets.
Secondly, we need to acquaint ourselves with some basic valuation methods.
On the quantitative side, this includes basic "expected value analysis." On
the qualitative side, I provide examples of evaluation methods used by sources
such as Kaiser Bottom
Fish.
In regard to map studies, I provide color-coded Intierra Resource Intelligence hot
play maps of the Cortez Trend area in Part
Five that you can minimize on your computer screen and refer to as you
follow my discussion of particular companies elsewhere in this series.
Nevada Exploration Geology 101:
As I mention in my article "The
Dual Nature of Gold and a Mystery," gold remains one of the most difficult
and costly metals to find and extract. Compared to iron, which must be concentrated
in geological anomalies five times more than it is randomly found in the
earth's crust to be economically mined, gold must be at least 1,000
times more concentrated than its random natural occurrence. Only about
one in five thousand gold mining claims results in a profitable mine. Most
rich surface anomalies quickly fade out rather than form economic trends.
The gold mined in Nevada is microscopic, dispersed, and typically found in
sedimentary rock. It is a true statement that gold can be found virtually everywhere
in California, Nevada, and elsewhere along the Pacific Rim, except that it
is normally extremely sub-microscopic and extremely dispersed.
The question is where is it concentrated enough to be economic to separate
it out from its surroundings.
For some reason gold tends to be much more concentrated in the earth's crust
in northern Nevada than in certain adjoining Western states, such as Arizona
which tends to be rich in copper but far less endowed with gold. Eastern Oregon
may have gold-bearing structures running north from northern Nevada, but they
have far more strata covering over them. This makes gold deposit both more
expensive to mine and less likely to provide seepage clues regarding their
whereabouts. Also, Oregon law prohibits the use of cyanide to leach the gold
out of ore.
The best way I can simplify a lot of complex geological theory is to point
out that gold tends to concentrate into economic deposits where nature performs
mechanical actions somewhat analogous to what a prospector does when he pans
for gold.
Gold is a heavy metal, so by swirling ore mixed with water in a pan, the prospector
gradually washes away the lighter raw earth elements, while skillfully keeping
reserved in the base corner of his pan a place to "trap" increasing concentrations
of the heavier residual gold particles within the "black dirt" (or "pay dirt")
that tends to surround it.
For the forces of nature to separate out gold from hot magma, it helps to
have swirling magma and pools of underground swirling water working together.
To trap and build up the gold deposits, we need to have gold-bearing fluids
that rise off the magma seep into cracks and fissures in the earth. This is
somewhat analogous to the way a miner sloshes increasing concentrations of "black
dirt" carrying gold towards the bottom corner of a pan. It also helps to have
types of rock whose molecular structures tend to grip and hold gold particles,
which are typically sedimentary rocks. Lastly, it helps to have nice long channels
of seepage where under various temperature and pressure conditions, the different
elements within the gold bearing fluids start to condense (mineralize) and
sort themselves out and form distinct deposits at different intervals. As an
example, as gold bearing fluids simultaneously push up diagonal crevices and
cool down, the base metals start to precipitate out first, starting with cobalt,
and then followed by lead, zinc, and copper. Further up the crevice, we get
arsenic, mercury, antimony, and gold. This is one reason why elevated arsenic,
mercury, and antimony concentrations in soil can be a clue regarding nearby
gold.
To be economically mineable, it helps greatly if the types of earth strata
that are relatively good at trapping gold get thrust up close enough to the
earth's surface to be highly accessible to miners. In order to find the gold
deposits in the first place, it helps if surface soil conditions can provide
various forms of "seepage" from major underlying deposits, such as through
very tiny little veins or from geological surface upheavals. It also helps
if faulting causes rocks to rub against each other, creating layers of rock
fragments (referred to as brecciation)
that make good traps to induce gold precipitation out of gold-bearing fluids.
Over the last five hundred million years, Nevada has experienced an unusual
confluence of all the aforementioned factors. As mentioned earlier in this
paper, some parts of the earth's crust just happen to be richer in gold particles
than others, and the northern Nevada crust just happens to be lucky that way.
You need deep cracks in the earth's crust to help bring magma closer to the
surface. Interestingly enough, a geologist told me that the earth's continental
crust is about half as thick in Nevada compared to elsewhere in the US.
The Cortez Fault system may go down all the way through the crust. Most of
its mountain ranges (which tend to run North to South, NE to SW, or NW to SE)
are flanked by faults. You need continued agitation, and Nevada remains the
third most seismically active state after California and Alaska. You need the
swirling water, and Nevada is very active with underwater geothermal activity
throughout the state. In fact, some geologists speculate that the "hot spot" that
now produces the geysers in Yellowstone National Park once existed under north-central
Nevada and helped concentrate gold. Lastly, for Carlin-style deposits, one
needs sedimentary rock to trap the gold in its fissures.
Nevada actually has two layers of sedimentary rock. One is near the surface,
and is so-so in hosting gold, but can do a reasonably good job of trapping
gold-bearing fluids beneath it. There is a second layer much deeper down called
the Lower Plate which has been much better at hosting gold deposits and has
been correlated with the major gold deposits of the Carlin Trend. You need
enough surface erosion and subterranean cracking, faulting, crustal stretching,
and geological instability over tens of millions of years to allow blocks (called "horst
blocks" in Nevada) of the deeper lower plate gold-bearing strata to get in
range of open pit mining.
In order to become a major gold producer, Nevada had to have the right geological
sequence. Nevada had to first act as an ancient sea bed to form the sedimentary
rock that acts as the "pan" to trap the gold, then later experience the cracking,
magma swirling, and geothermal action that "swirls the gold in the pan."
At the January 2005 Vancouver Resource Investment Conference, Joe Kizis, President
of Bravo Venture Group, summarized for me the three major variables that create
economically mineable gold formations:
1) Source of fluid. Some kind of magma-related event creates gold-rich
fluids that get pushed up through the earth's crust. One typically needs
hydrogen and sulfur in solution to carry the gold.
2) Structure. The gold bearing fluids have to find cracks or permeable
strata to rise towards the earth's surface. Sometimes gold-bearing fluids
can pass through rock formations without precipitating out the gold. Sometimes
the gold fluids will rise vertically through a crack, and then hit a horizontal
strata of brecciated rocks
ground into pebbles by faulting action and then fan out horizontally.
3) Host environment. Something has to precipitate out the highly dispersed
gold in the gold-bearing fluids rapidly enough to create economic gold concentrations.
The precipitation process is influenced by such variables as temperature,
pressure, chemistry, and fluid mixing. The precipitated gold also has to
precipitate against some kind of host rock that does a reasonably good job
of acting like a gold particle "sponge."
Chemistry is relevant...
It helps to know something about chemistry to understand the clues geologists
look for to find the deposits that can send your junior gold mining stocks
skyward.
One type of chemical separation involves rocks that are rich in iron. The
iron may bond with the sulfur in the gold-bearing fluids, forming pyrite ("fool's
gold"), which in turn may strip away the sulfur as a carrier for gold in solution
and cause the gold to precipitate out. The Roberts Mountain formation in the
Cortez Trend consists of a "platy" silty limestone rich in a certain type of
iron that tends to react with gold bearing fluids and fix the gold to itself
and create deposits over a "platy" stratum rather than allow it to pass by.
Another chemical example involves the presence of water. It can also precipitate
gold by changing the acidity, temperature, and salinity of the gold bearing
fluids. The presence of hot water can suggest a heat pump system that helps
circulate water and enhance the gold separation process. Hot water is found
in deep drill holes throughout the Cortez Trend.
Finally, a third example may involve oil and natural gas, in which the same
hosting structures that trap oil and gas can also trap gold-bearing fluids.
Carbon molecules in the methane interact with the gold bearing fluids to separate
out what becomes graphite, gold, and water. Most Carlin deposits have "carbon
front" features, to include those found along the Cortez Trend.
Macro earth science is also very relevant...
Last, but not least, I would be remiss if I did not touch on plate tectonics,
whose several hundred million year-long alternating compression-stretch cycles
have played a huge role in Nevada's geological history, and help explain the
age, direction, and magnitude of gold-bearing fracture zones that tend to run
NNW, WNW, and NE. I describe all of this again with some more details in Part
Five.
Roughly 700-900 million years ago the Australian
continent may have rifted away from the western edge of the North American
land mass. By one
interpretation, the continental
margin of North America ran through north central Nevada. As Australia
drifted away, the oceanic area in-between started piling up marine sediments
for several hundred million years which subsequently formed excellent host
rock for gold deposits.
Then about 300-400 million years ago the rifting apart process changed 180
degrees. A new cycle of oceanic and continental plate collision began that
would last roughly 350 million years. Geologists call these types of mountain-building
collisions "orogenies." .Two
Pacific tectonic plates (the Kula
and Farallon plates, to be precise) and the North American Plate began
to converge relative to each other.
This created enormous compressional forces
that started folding up mountain ranges perpendicular to their principle
stress direction. Western North America began to fold like an accord ian
between its west coast all the way to where Denver, Colorado and the edge of
the eastern Rocky Mountains stand today. Part of the Pacific plates dove underneath
the earth's crust ("subduction"),
but another part splayed off and thrust more horizontally into the earth's
crust to create the folding action. Fifty different exotic terrains were sutured
on to the West Coast during the Mesozoic era (248 to 71 million years ago),
adding 25% to the continental crust of western North America.
Nevada's geology began to resemble a train wreck with strata getting cracked,
scrunched, and folded up in many different directions. Parts of the oceanic
plates subducted under the crust melted and formed magma "plutons" that
rose towards the surface and formed intrusive features associated with gold-bearing
structures that I show in diagrams in Part
Five.
About 40 million years ago, the extreme compressional forces subsided as the
bulk of the Kula and Farallon tectonic plates slipped underneath the North
American continent for good. In fact, the relative compression shifted 180
degrees once again, and a new period of relative rifting began. In the last
20-30 million years, the Basin
and Range area, which includes the mountains of Nevada, has seen a stretch
process that geologists call an "extension." They claim that when the Farallon
Plate completed its slide under North America about 40 million years ago
(with the exception of a remnant called the Juan de Fuca Plate that still subducts
off the Pacific Northwest to this very day), this coincided with the beginning
of a rebound effect whereby the western US stretched out about 150 km. This
continental stretching continues to this day, with California moving away from
Colorado at about a centimeter a year. Some day an ocean will probably develop
between the two areas, much like what once happened when Australia drifted
away from North America.
When the tectonic plate rebound process began about 40 million years ago,
the Pacific Plate that
supports the Hawaiian islands executed a counterclockwise rotational
shift and changed its thrust direction. The North American continental plate
also changed direction, but not as much. A huge pulse of gold-bearing fluids
surged from very deep in the earth towards the surface in Nevada, traveling
through the myriad cracks created in the prior geological ages. This created
most of the Carlin-style gold deposits found today.
Western North America's geological formation stabilized enough 40 million
years ago so that the general drainage pattern we now call the Colorado River began
to form. New "fault-block" mountain ranges have been developing as the
continual stretching (or continental "spreading" -somewhat
analogous to "seafloor
spreading" --by another geological interpretation) widens cracks between
mountain ranges.
The mountainous areas of the continental crust continue to maintain their
elevation since they rest on the earth's mantle. However, the valleys between
them include cracks that are steadily widening. The rate in which valley floors
drop depends on the rate in which they fill with eroded materials compared
to the rate in which the widening cracks create new void to be filled. Death
Valley, California, is an extreme example where a relatively low rate of
erosion from less than 2 inches of rainfall a year compared to a high rate
of valley widening has dropped the valley floor to 282 feet below sea level.
Amidst all this, exterior oceanic tectonic plate pressures continue to apply
along the Pacific Rim at odd angles, one good example being the San
Andreas fault. Nevada and California remain unstable, and still experience
periods of volcanism, earthquakes, and rifting.
John Kaiser's commentary below provides some other interesting details regarding
this history. It is contained in his article about Gateway Gold Corp, which
operates NW of the Carlin Trend:
Key buzzwords associated with Carlin-style gold deposits in Nevada are "Upper
Plate", "Lower Plate" and "Roberts Mountain Thrust". During Cambrian to Mississippian time
[345 to 320 million years ago] northeastern Nevada had been a continental
margin that shed sediments into an oceanic basin. The basin sediments graded
westwards from silty carbonates (today known as Lower Plate) to siliciclastic
rocks (Upper Plate). Starting in Late Devonian time [367 to 408 million years
ago] as a result of "compressional tectonics related to the Antler
Orogeny" the western sediments were thrust eastwards over the silty carbonates,
like one plate sliding over another. The result is two distinct sedimentary
sequences, one stacked on top of the other. The thrust plane, or the interface
between the Upper and Lower Plates, is called the Roberts Mountain Thrust.
The thrusting created highlands which eroded eastward to form a sequence
of clastic rocks
["fragments of rocks that have been moved individually from their original
place of formation"] called an "overlap assemblage". This was followed by
additional periods of thrusting, folding and uplift which shoved more Upper
Plate rocks on top and injected a high degree of complexity. Magmatism centred
on the crustal zones of weakness today known as "Trends" in Nevada began
in the Late Triassic (208+ million years ago) and continued periodically
into the Late Tertiary (2 million years ago).
The extensional activity that created the familiar north-south trending "basin
and range" topography began about 20 million years ago. The problem in Nevada
is that the ideal Lower Plate host rocks are buried beneath thick layers
of less favorable Upper Plate rocks, but thanks to extensive faulting and
folding this spatial relationship is not uniform. An important regional exploration
goal is the identification of Lower Plate "windows" within the gold trends.
Lower Plate windows developed when giant blocks of rock bounded by faults,
also known as horsts, underwent uplift. [Actually by another geological interpretation,
the horsts stood still and valley areas adjacent to them drop]. Subsequent
erosion of the uplifted horst would have shaved the topographically elevated
Upper Plate rocks down, leaving the Lower Plate rocks exposed or much closer
to the surface than the Lower Plate rocks outside the "window". The presence
of Lower Plate rocks does not, of course, guarantee the presence of a major
gold deposit; it merely offers better host rock conditions for the development
of a major deposit. A plumbing system and structural preparation of the rock
also need to be present, along with gold bearing solutions. Gold mineralization
can occur in Upper Plate rocks, but generally does not form large gold deposits
because the Upper Plate sediments lack the gold "sponge" characteristics
of Lower Plate rocks. Upper Plate gold mineralization, however, can be viewed
as leakage from a deeper plumbing system which may have caused big gold deposits
to form in deeper Lower Plate rocks.
Below is a sample cross section illustration created by White Knight Resources
regarding one of its current drilling projects in its Slaven Canyon project
that illustrates some of the structures just described by John Kaiser.

For another more detailed overview of Nevada geology, I would refer the reader
to the article "Geology
of Nevada" (Price, Henry, Castor, et al) that appeared in Nov 1999 Rocks
and Minerals. The article states, "Most, but not all, ore deposits in Nevada
are associated with igneous [volcanic] activity. In some cases, metals came
from the magmas themselves, and in other cases, the magmas provided heat for
circulation of hot water that deposited metals in veins and fractured sedimentary
rocks. Some spectacular mineral specimens occur in ore deposits that formed
when magmas intruded and metamorphosed sedimentary rocks. Even today, driven
locally by deep circulation along faults and locally by igneous activity, hot
water shows up in numerous geothermal areas."
As far as other references, Nevada Pacific Gold provides a good glossary of geological
terms. I would also point the reader's attention to various geological
age charts easily "Googleable" on the Internet.
Gold exploration summarized
In a very paradoxical way, finding gold seems to be both incredibly complicated
and simple at the same time. Gold exploration may be a very uncertain science
(in a statistical sense) if one tries to build a predictive model from scattered
clues. As mentioned earlier, gold is so rare, and so many disparate geological
variables have to interactively align themselves to produce economic gold deposits,
that to really get this down to a science one would probably need a combination
of a supercomputer with several thousand times more processing power than the Earth
Simulator combined with a huge army of robotic devices that can systematically
canvass vast geographic areas of interest and very cheaply perform both deep
drilling and core sample analyses.
Conversely, using comparative logic, the process of finding gold might be
incredibly simple. Because gold deposits are so anomalous and freakish, if
one finds a rich gold deposit somewhere, it becomes intuitively obvious that
the most likely areas that also bear rich gold deposits are the ones that are
geographically the closest and are geologically the most similar. Hence, geologists
typically model the factors behind economically successful deposits in order
to make reasonable analogies in piecing together emerging evidence from new
exploration areas.
Conversely again, modeling can become complicated when geologists seek to
understand how all the key geological formations in their area of interest
were formed over time, as well as reconstruct a "mental movie" regarding how
gold-bearing fluids went about their way forming economic deposits.
Finally, in the real world, what can make exploration geology extremely easy
again is when a preponderance of evidence from drilling results and geological
modeling makes the magnitude of a discover fairly obvious, yet such factors
as market emotion, market manipulation, corporate bureaucratic politics, government
intervention, and insider conflicts of interest work together to create distortions
in free market pricing mechanisms and cause exploration properties to become
grossly undervalued.
"Expected Value " Analysis and the Kaiser Bottom Fish Method
"Expected value" analysis is a very handy tool for business and investment
decision-making. One determines the "expected value" of an outcome by multiplying
the expected payoff by the probability of the payoff, and then by comparing
alternatives.
As an example regarding how we can calculate expected value, suppose you have
to choose between two bets, "A" and "B". For Bet "A" you have a 10% chance
of making $100. You have a 90% chance of making zero. Your "expected value" of
this bet is $10. For Bet "B" you have a 5% chance of making $500. You have
a 95% chance of making zero. Your "expected value" of this bet is $25.
If you are not risk averse, and can spread your risks across over enough bets
so that you tend to reap the expected value of all the bets, then a rational
speculator would prefer bet "B" to bet "A" even though the odds of winning
bet "B" are half of those for "A."
Of course in the real world most sane individuals shy away from playing purely
by expected value calculations. The big difference between the individual of
average means and an insurance company, is that the individual simply can not
afford the catastrophic outcome of losing a particular bet, whereas the insurance
company can spread its risks across enough bets so that it can reasonably rely
on achieving the expected value of all of its gambles combined in order to
make money.
If we are going try to make some kind of simplified, back of the envelope,
cash on cash analysis regarding a junior mining company operating along the
Cortez Trend, we need to know at least three things. First, what is a likely
payoff. Secondly, what are likely odds of achieving such a payoff. Third, is
the exploration company that we use as a vehicle to place our bet "for real"?
Assembling our Lucky Bingo Chart
Let us imagine that discovering a five million ounce deposit along the Cortez
Trend is entirely plausible for a hypothetical junior mining company given
Placer Dome's discovery of 15 million ounces in proven and probable reserves
in the Cortez Joint Venture area. Let us imagine we have ten really good drilling
projects in different areas based on very competent geophysical studies. Suppose
we assume the probability is 25% that at least one of these projects will hit
a 5 million ounce target, even if it means drilling thousands of drill holes
over a period of several years.
Imagine that the price of gold will likely be above $450 an ounce by the time
our deposit gets mined, and that our junior mining can send its ore to a major
gold mining company's production and processing facility in the area. Now we
need to figure costs per ounce to determine net profit. This can get tricky,
because out junior exploration company might strike a deal with a major to
do the production rather than go into production itself, so the cost analysis
may actually be done from the perspective of a low cost producer such as Placer
Dome.
Regarding production cost comparables, in Part
Three, I note that Placer Dome's reported cash and total costs at its
Cortez Joint Venture facilities are $200 an ounce. BacTech, with a bio-leaching
facility located close by within the Cortez Trend, claims low to mid-$200's.
Newmont's total expected 2004 cash costs in Nevada are $250 an ounce. Queenstake,
outside of the Cortez Trend, weighs in at $270 total per ounce in its 2003
Annual Report. Shall we say then $250 an ounce for mining and processing
costs? Plus add another $75 an ounce as an intuitive guess for expensed capital
investment (depreciation, depletion, and amortization) general and administration,
and non-deferrable tax liabilities. That might bring us to $325 an ounce
total. Incidentally, gold dipped to a low of
$252.90 in June 1999, a price that threatened to put roughly half of all
gold mining companies out of business, so if we bring this break-even number
forward five and a half years at a 5% cost increase a year, we get something
close to the $325 estimate.
Imagine that in order to finance continued drilling, the junior mining company
has to continually give away 50% of its ownership of its various properties
to various major gold mining companies, who earn their 50% interest by putting
up all the capital required for continued drilling until all the properties
eventually look like Swiss cheese.
Lastly, imagine that by the time the gold mining company either "hits" or
has tied up all its properties with drilling deals, it has diluted its shares
out to 75 million.
We might perform the following calculation to derive an expected value for
the stock price. Of course if the current stock price is well below this expected
value, we might have a bargain bet.
5 million ounces * 25% chance of discovery * $125
net profit per oz * 50% retained interest
----------------------------------------------------------------------------
75 million shares
The expected value = $1.04 a share. Quite a few of the junior mining companies
mentioned in this article are trading at well under $1.00 a share. Maybe I
am being too generous in my 5 million ounce target assumptions, $125 net profit
per ounce, or 25% chance for a single big hit among all of our ten hypothetical
project areas. But then again, maybe this time it is really different. This is the
Cortez Trend. If we have very good geophysical data that puts us very close
to very promising structures, maybe this is not too optimistic. Look at the
Carlin Trend map in Part
Five. It looks like about 30% of the property frontage along major fault
areas has hit a major gold deposit. We also see gold along cross fault structures.
Let us try more aggressive assumptions. Imagine if we really believe
that in a few years that gold will go over $750 an ounce (I am on record for
stating my strong belief that it is going well over $1,000
an ounce in five years). Imagine that our total costs rise to $375 an ounce
(let's add another $50 for extra non-deferrable taxes and inflationary cost
increases) so that we now net $375 an ounce in profit. Also suppose in addition
that there is still a 25% chance our brave little company can discover 15 million
proven and probable ounces just like Placer Dome.
15 million ounces * 25% chance of discovery *
$375 net profit per oz * 50% retained interest
----------------------------------------------------------------------------
75 million shares
Now we are up to an expected value of $9.37 per share. And this does
not include the "growth premium" investors would likely pay for the company
as a going concern with possible future projects besides our initial ten properties.
Nor does it include the appreciated real estate value of its leasehold properties
in hot play areas.
Of course we can and should tweak all of the aforementioned assumptions in
different ways to perform a sensitivity analysis. Many of my assumptions were
wild guesses for illustrative purposes and should be questioned in detail by
anyone conducting an analysis for investment purposes. A real full blown financial
analysis would involve a pro forma that scrupulously analyzes and makes projections
of itemized cost elements on a line item by line item basis in absolute numbers,
looking at after tax real cash flows, and would go beyond simply guesstimating "per
ounce" numbers.
As another note, I skimmed over performing a standard net present value and
detailed after tax cash flow analysis. This is because gold mining has some
very peculiar characteristics compared to other businesses.
In a commodities bull market, gold price behavior mocks inflation rate and
historical bond yield assumptions typically used to help derive discount rates
to determine net present value (NPV). As mentioned in my article "General
Market Characteristics of Gold," gold has historically always done best
in a bond environment with negative real rates of return, such as what America
experienced in the 1970's. During that "stagflationary" period, America experienced
double digit inflation and continued negative real interest rates. Although
gold had held below $50 an ounce throughout the 1960's until April 1972, it
soared to $850 by Jan 1980.
As another historical aside, gold was increasingly suppressed throughout most
of the 20th century as a form of money, but I believe that the cyclic wheel
of history is now turning in the other direction for macro-political reasons
that I have already alluded to in Part
One of this series. Central bankers are increasingly losing their grip
and gold is increasingly resuming its ancient role as money of last resort.
I expect a long period of accelerating inflation in which we will continue
to experience negative real bond yields under conditions more extreme than
those of the 1970's.
In regard to taxes, I agree with the policy of Goldcorp which currently withholds
a third of its production,
awaiting higher prices. Since gold is money, from a purely cash
conservation viewpoint, I do not see why a gold mining company should ever
market any more of its production than what is required to meet expenses. A
gold mining company may be able to borrow against the gold bars it accumulates
in a vault without selling any of it on the open market, in this way financing
acquisitions in a similar manner to real estate pyramiding without triggering
a taxable even.
Interestingly enough, even though Iamgold has been forced by one of the African
countries where it has some mines to sell its production to trigger a taxable
event, it chose to buy back gold to hold in a vault as part of its liquid capital
as part of an economic/political statement in favor of gold. If this approach
becomes more widespread within the industry, figuring effective real tax rates
will become even more difficult.
Using expected value analysis for value-oriented "speculative" investing
John Kaiser's "Rational
Speculation Model" provides a chart that shows generalized industry odds
that a company will "hit," based on its current phase of exploration.

Exploration is very risky, but can also be very lucrative. On the reward side,
Rudi Fronk, President/CEO of Seabridge
Gold pointed out in his Korelin
interview that through exploration, with relatively little capital investment,
he can reap 70% of the Ultimate Project Value (UPV) of a mine.
On the risk side, Miranda
Gold observes, "Out of 1000 projects that may be available, 100 of them
may have significant potential and require further exploration. Of these
100 projects with potential, 10 of them may have a discovery. Of those 10
with a discovery, one of them may become a mine." (For readers interested
in an actual expected value case study analysis for an exploration play in
Australia, please note "Measuring
Exploration Success" by Lord, Etheridge, et al).

One way to substantially reduce risk, while retaining tremendous upside with
junior mining companies, is to try to catch their stocks when their flagship
projects are in the "gestation" phase, as noted in the chart
above and discussion provided by James Puplava. Typically after a run-up
following a discovery, junior mining stocks begin to fall off from a lack of
news and excitement as reality sets in. The stock price consolidation period
that comes just before a feasibility study provides visibility to future production.can
be an excellent time to accumulate shares, particularly if the junior company
also has plenty of other projects in the pre-discovery stage.
Lawrence Roulston summarized
the junior mining investment case in his 4 Dec 2004 Korelin
interview when he said:
I tend to focus on the smaller companies. Part of the reason for that is
if you look at Newmont, a brand name in the gold market, you are effectively
paying two times net asset value for Newmont right now. There is such an
expectation of a rising gold price that a higher gold price has already been
factored into the shares of Newmont. Now that is not to suggest that the
price of Newmont will not increase with the gold price, because as the gold
price moves up, people will expect a continually higher gold price, and Newmont
will move up along with the gold price. I prefer to buy things at a discount
rather than paying a premium. So I like looking at the smaller companies.
Companies that have not yet been discovered, if you will.
I find that the best value is in companies that have an early stage gold
deposit. I am not talking about a company putting its first hole in the ground
hoping they are going to hit something, but there are a lot of situations
out there where companies have put in tens or even hundreds of drill holes
into something, but they do not yet have enough data so that they can call
it a reserve. So these situations that we call an inferred resource are typically
valued at about $10 an ounce in the ground. Now the benefit of buying a situation
like that is number one you are getting way more exposure to gold than if
you bought a major or if you bought bullion. For example a $10,000 investment
in a company that has an inferred resource will give you an exposure to a
thousand ounces of gold in the ground. If you bought bullion, you would have
to invest $450,000 to get the same level of exposure to the upside in the
gold market. And the second thing is, a reserve is valued at about $100 an
ounce in the ground, and an inferred resource at $10. So you have the business
upside as that project moves through the exploration development cycle. You
have a ten for one upside potential from the company adding value to its
deposit.
On the downside, just because a project advances from a target drilling stage
to pre-feasibility stage does not mean you are home free. Although the odds
may have advanced from around 2% to 50%, things can still go wrong that prevent
the project from ever becoming a mine, in which case the value of this portion
of your investment may deteriorate back down towards zero. The potential to
lose ones principal is what makes these exploration plays speculative,
as opposed to holding a mining company that controls proven and probable reserves
and/or has actual production, in which case there is underlying investment
value.
Also on the downside, both Doug Casey and Rick
Rule pointed out in their December 2004 San Francisco Gold Show panel
discussion that owning a junior mining can be like holding a burning match,
to the extent that many companies steadily dilute their stock while using
it as currency to acquire properties or pay for overhead. Of course, adding
more shares is not such a bad thing so long as management can steadily accrete
quality resource ounces per share over the long run. The trick is to know
which management teams can successfully parlay stock issues to acquire more
resources to ultimately accrete quality ounces per share, and which ones
are simply diluting the company out from under shareholders while blowing
smoke.
Using the probabilities in John Kaiser's chart, you can run your analysis
in two directions. You can start with a potential ore body, and then figure
a rational price to pay per share given the current stage of exploration. Conversely,
you can start with the current share price at a particular stage of exploration,
and determine what size ore body that implies. In essence, that is what John
Kaiser does visually in the chart below, using White Knight as an example.
The purple square for White Knight shows a $52 million market cap for the
value of the whole company. It is listed in the target drilling column on a
channel line that suggests that if Slaven Canyon is the only property that "hits" for
White Knight, it would need to be around a $2.2 billion project to justify
the odds. This chart does not factor in White Knight's 14 other
properties or a growth rate for the company. It also leaves out the leasehold
real estate property value of White Knight's other properties, which will probably
go up in value purely as real estate speculations if the staking gold rush
increases in the Cortez Trend area. At $450 an ounce gold, if we assume mining,
processing, overhead, and non-deferrable tax costs to come to $325 an ounce,
providing a net project value of $125 an ounce, this might suggest a risk-adjusted 17.6
million ounce discovery to produce $2.2 billion in Ultimate Project Value.
At $750 gold, let us take the aforementioned $325 cost base, let us intuitively
add $50 an ounce for extra non-deferrable taxes on extra profits, to get a
$375 per ounce cost base. That leaves us $375 net profit an ounce. That implies
a risk-adjusted 5.86 million ounce discovery.
Of course if White Knight did hit a 17.6 million ounce discovery tomorrow,
at $450 an ounce gold, $2.2 billion in project value divided by 65.5 million
fully diluted shares gives us a $33.58 stock price. White Knight (TSX-V, WKR)
currently trades well below $1.00 a share. John Kaiser has placed the Slaven
Canyon project on an upper expected value trend line, where it may be fully
valued based on a risk adjusted share price, but not what the price
would be if the company "hits" (in which case we have removed a huge part of
the risk). In his June 16, 2005 article "Cortez
Trend Catches Fire," John Kaiser discusses the Placer Dome news announcement
that jumped White Knight's share price.
