Real mining has real methods....and why do i say that? Just because it is IMPORTANT, to the newbie investorts to understand it hear at ORXX and there at any OTHER MINER. COC is the chain on the lock and key to the resource, anythingless; could be salt and pepper!

<<..EDITORIAL & OPINION - COMMENTARY -- Resource estimation and
geological constraints,
Part 2
By Mark O'Dea, Michael Michaud & Ross Sherlock
Without a doubt, the most important step in deposit resource estimation is formulating a
well-constrained geological
model for the orebody, its shape and the structure and stratigraphy that controls it. This
model serves as the
backbone of the resource calculation, and it is the integrity of the resource estimate that
ensures the choice of
mining method, production rates and processing methods. The projections of cash-flow
have integrity too.
When a resource model is not sufficiently constrained by geometrical and geological
knowledge, there may be an excess of
averaging between the higher and lower grade zones of the deposit. This can yield a
higher-tonnage, lower-grade resource
estimate and a less accurate picture of the distribution of mineralization than can a model
with better geological control.
Taking an epithermal-style deposit as an example, and using the methodology we
advocate, the first and most critical step in a
resource calculation is to determine the geological features that control the mineralization.
Is the mineralization localized along fault
zones? Does it occur with silicification? Does density of veining or fracturing provide a
good indication of metal tenor? Is
hydrothermal brecciation important? Does host rock lithology play a role in localizing
mineralization? Can solid boundaries be
drawn around mineralized or potentially mineralized bodies? Once the essential geological
criteria that are associated with
mineralization have been established, they form the basis for defining "geologically
constrained" bodies of mineralization. The
information that reveals the boundaries of these zones generally comes from surface data
extrapolated downdip and along strike,
correlated with information from the drill logs. All of the assay results that intersect these
corridors of mineralization potential go
into the calculation that estimates the grade of the zone.
The accurate construction of geologically constrained zones of mineralization is extremely
important for subsequent geostatistical
analyses. These zones make it possible to domain the assay population and gain an
understanding of the "real" metal distribution
within a mineralized zone. A positive consequence of determining accurate metal
distributions is the delineation of "deposits within
a deposit." Conversely, discrete high-grade deposits can easily be masked within
low-grade bulk-tonnage disseminated deposits if
an inappropriate geological model is applied. It must be stressed, therefore, that, in the
absence of geologically constrained zones
of mineralization, geostatistical techniques can produce unreliable and unpredictable
results.
Mineralized envelopes are not delineated by down hole assay data. They do not come
from using an arbitrary cutoff grade, and
they do not introduce a statistical bias to either low-grade or high-grade assays. Instead,
the correct technique is based on
identifying the fundamental features that host mineralization, and determining the subset of
the data that comes from inside the
boundaries of those features. This approach can be applied to the entire spectrum of
hydrothermal mineral deposits, from porphyry
coppers to volcanogenic massive sulphides.
The largest potential error in any resource model is in the way geological boundaries are
linked from one drill hole to the next.
Geological acumen and a firm understanding of the property geology are the most valuable
assets in any resource estimation. No
one can overemphasize how important it is to integrate surface mapping and accurate
core logging data into the resource model.
Without a robust geological model, resource estimates will seldom be reliable; in fact, their
results can be detrimental, generating a
false sense of confidence and hurting the investor. Resource estimation integrates the
geologist, who understands the deposit; the
mining engineer, who evaluates minability; and the geostatistician, who crunches the
numbers. We cannot leave it just to the
academics.

Let's All Read about the NEED for Palladium afterall the SEMs say we have a third OPT
of the PGMs anyways:

<<..EDITORIAL & OPINION - FACTS 'N' FIGURES -- Price rise undercuts palladium
market
The volatility of palladium supply and the consequent rise in prices put the long-term future
of the palladium market
in doubt, according to a new study.
As prices of platinum and palladium converge, one of the major reasons for using
palladium in a number of applications is
disappearing. Moreover, although palladium is technically better than platinum in its main
auto-catalytic application, the perception
of relative stability in the long-term supply of platinum may result in a move back to it. In
the meantime, thrift on the part of
consumers may result in the loss of some of the traditional markets for palladium, such as
dentistry and electronics.
The adoption of palladium as the main automobile emissions catalyst has led to its
emergence as the principal platinum group
element, rather than platinum.
The implications, in terms of both the volume and value of the market, are far-reaching,
particularly at a time when the largest
traditional source of palladium -- Russia -- appears incapable of meeting demand with new
production. As a result, the palladium
market since 1996 has been in a severe deficit, dependent on releases from the large but
finite Russian stockpile built up over
many years of production.
Autocatalysts, by far the largest use of PGMs, accounted for 45% of total consumption in
1998. Palladium consumption was 4.2
million oz., about 50% of total consumption. Efforts to meet ever-tightening automobile
exhaust emission standards in Europe and
North America have resulted in demand for autocatalysts with heavy loadings of
palladium to oxidize hydrocarbons.
Palladium's resistance to heat has made it particularly effective in starter bricks, located
close to the engine, which heat up quickly
and control emissions after startup. They are also suitable for small, fuel-efficient cars
with high engine speeds, such as those on
the European market. Platinum electrodes in fuel cells have the potential to be the next
major end use for platinum, contingent on
the fuel cell being adopted as the power source for zero-emission vehicles. Several major
car makers plan to introduce fuel-cell
cars on a commercial scale by 2004-2005, by which time some 100,000 fuel-cell cars
could be on the road. Each such car will use
about 10 grams of platinum, or about 320,000 oz. for every million vehicles.
Jewelry remains the largest use for platinum, with considerable growth in demand from
China coinciding with a decline in its use in
autocatalysts. Japan and China have the largest platinum jewelry markets, having used
1.25 million oz. and 500,000 oz.,
respectively, in 1998.
