Success in mining and mineral exploration depends on the ability to make sound
decisions based on solid evidence. ALS Chemex understands that important
decisions pivot on the accuracy of our results. Our processes ensure our clients
receive the best information possible to assist with their decision making.
A System You Can Trust
The ALS Chemex quality system complies with the requirements of the international standards ISO 9001:2000
and ISO 17025:2005 and operates in all laboratory sites. Our custom LIMS (Laboratory Information Management
System) has been designed using these requirements to enhance laboratory quality assurance protocols and to
provide the traceability necessary for today’s stringent reporting requirements.
The Open Lab™ Initiative
Site audits give only a snapshot of what is occurring but complete audit trails present the chain of custody and
records for every action on a sample. The same level of record keeping that has been required in the pharmaceutical
and environmental testing industries for years is now available for mineral exploration testing.
Through new technology, ALS Chemex provides a deeper and more complete view into its laboratory and it is with
this that we invite you to look over our shoulders at every step your samples take in their analysis. We are able
to provide this service to our clients with the implementation of GEMS, a custom-written laboratory management
interface to our centralized database.
The Open Lab™ also possesses interactive functions that make it possible to discuss analytical results withlaboratory managers on-line, and to request information or selective re-runs with only a few mouse clicks.
Webtrieve™
The Open Lab™ is made possible with the development of Webtrieve™, the on-line interface to our database.
Through Webtrieve™ clients can access results and download certicates of analysis as well as track their samples’
progress through the laboratory and obtain important quality control information.
When we receive your samples and at each subsequent stage of their analysis, their barcodes are scanned and
data regarding their location and results are stored. As soon as it is captured, data is available for viewing and
retrieval by the client via an on-line, encrypted account. This real time data capture and display allows for viewing
and retrieval of partial results from each separate procedure. As well, this partial data can be accessed prior tocompletion of the entire analysis. Your samples’ progress can be tracked through the Workorder Progress page on
Webtrieve™ which displays information on which analytical steps are complete, and partial data that is currently
available.
Along with results, qualied persons will nd all the tools necessary for the proper signing off of data released to the
public. Audit trails are produced and updated each time your samples are moved allowing for complete traceability
of the time they spent in our laboratory. QC data for the sample preparation and analytical stages can also be
obtained through Webtrieve™ including preparation sizing test data, and performance results for standards and
duplicates run with your samples.
All documents can be viewed and retrieved from Webtrieve™ including Certicates of Analysis and method
descriptions.
This new technology gives you instant access to the deeper and more detailed information regarding the laboratory
processes that is now required by regulators. Just as critically, this information is readily available 24 hours a day
through the World Wide Web.

Obtaining accurate results begins with obtaining representative samples. ALS
Chemex approaches sample preparation with the same rigorous quality control
procedures and careful attention to detail as any other stage in analysis.
The Most Important Step
The purpose of sample preparation is to produce a homogeneous analytical sub-sample that is fully representative
of the material submitted to the laboratory, unless the client wishes to assess a particular size fraction. The actual
sample preparation procedure selected will vary depending on the type and size of the sample submitted.
Sample preparation is the most critical step in the entire laboratory operation. ALS Chemex has specied certain
parameters that must be achieved in preparing samples to ensure that homogeneous and representative sub-
samples are submitted for analysis. These parameters will not be achieved if sample size exceeds the equipment
capacity.
To ensure that your samples are prepared correctly we recommend that you discuss your proposed requirements
with the laboratory manager and advise our staff about any mineralized samples submitted that may require
additional equipment clean-up to avoid contaminating following samples.

Sample Preparation - Limitations & Assumptions
Crushing
Every reasonable endeavour will be made to achieve the specied degree of neness for the crushed product.
However, it is inevitable that the ultimate homogeneity and three dimensional aspect of the resultant fragmentsand grains making up that product will be a direct function of the fabric, mineralogy, texture and hardness of the
material being crushed. Thus while feed material possessing varying degrees of weathering grain size, silicication,
mineralization, bedding, foliation or schistosity is actually crushed to the specied degree of neness as dened
by the jaw setting, anisotropic pieces exceeding the desired neness in one or two dimensions may nevertheless
pass the jaws unimpeded. In these instances, repeated reintroduction of the crushed product through the crusher
is the only remedy, and will only be done at the specic request of the client and at additional cost than quoted for
single-pass crushing.
Pulverizing - LM5
Whether the required neness (nominal 85% passing 75 microns) can be achieved in one pulverizing pass (in
very large LM5 bowls) is dependent on a critical range of physical variables. Those variables over which the client
alone has a degree of control, or at least prior knowledge of, are initial sample weight/size, SG, hardness, and the
mineralogy and texture of the samples. The only variables that the laboratory can control are pulverizing time and
(by applying experience, observation and trial screen sizings of the initial pulps) the optimum sample size per pass.
The sum total of these variables is unique to each project and on occasion even to each submission, and cannot
always be predicted at the time of preparing the quote.
Because ALS Chemex is not in a position to quantify in advance these outcomes, the initial assumption made for
pricing purposes is that one, 6 minute pass in one LM5 bowl at a weight of 2.5 to 3kg (maximum) will be sufcient
for the majority of the samples. Should the empirical facts demonstrate otherwise, the client will be advised and the
protocols changed to maintain the standard of pulverizing that has been mandated by the client. Additional costs
may apply and again this is done in consultation with the client.

Gold and other precious metals continue to be highly sought after by mining
and exploration companies worldwide as a result of their strong prices in recent
years. ALS Chemex has the analytical tools and years of expertise to help you
with this potentially valuable search.
The selection of the best method for the accurate determination of a precious metal is highly dependent on the
nature of the sample and the objective of the analytical result. The methods described in this section are effective
alternatives for the determination of gold, silver and platinum group metals.
Gold
Fire Assay Fusion
For fully quantitative gold contents, the re assay procedure is still the preferred choice of laboratories all over
the world. However, it should also be recognized that a wide variety of minerals and metals such as chromite,
base metal suldes and oxides, selenides and tellurides for example, in moderate to high concentrations, can
interfere with the re assay process, generally leading to low precious metal recoveries. With prior knowledge of
the presence of these minerals and metals, ALS Chemex can modify ux constituents and increase ux to sample
ratios to improve recoveries. In most cases, a reduction in sample weight will yield higher precious metal recoveries,
particularly in the presence of the interferants mentioned above. For optimum gold and PGE recoveries for most
sample matrices, ALS Chemex recommends a 30g maximum charge weight.

patterns in trace elements as indicators of what may lie deep below.
Find the Methods That Suit You
The effectiveness of a geochemical exploration program is largely dependent on the availability of analytical
methods that properly meet the requirements of the problems at hand. Element coverage, detection limits, reliability
and cost are often the main factors considered by explorationists when choosing an analytical method for a given
sample type.
ALS Chemex offers a wide range of multi-element and single-element methods that can satisfy the requirements
of today’s exploration geochemists, both technically and economically. The analytical methods described in this
section include different sample decomposition procedures, such as aqua regia and multi-acid digestions, fusions
and selective leaches. The instrumental analytical techniques comprise inductively coupled plasma with atomic
emission spectroscopy or mass spectroscopy, atomic absorption, x-ray uorescence and infrared spectroscopy.

Ultra-Trace Level Methods Using ICP-MS & ICP-AES
Aqua Regia Digestion
Although some base metals may dissolve quantitatively, in the majority of geological matrices, data reported from
an aqua regia leach should be considered as representing only the leachable portion of the particular analyte.
The recovery percentages for many analytes from more resistive minerals can be very low, but the acid leachable
portion can also be an excellent exploration tool.
In order to be able to report the widest possible concentration range, this method uses both the ICP-MS and the
ICP-AES techniques.

mobility are important tools in understanding geological environments.
The selections of analytical packages on this page are designed to offer
comprehensive information for these studies.
The nature of lithophile elements and the matrices they occur in require stronger dissolution procedures to separate
them from the bulk matter. The most accurate results will therefore be obtained using fusion as the separation
procedure or through direct analysis. X-ray uorescence is the preferred technique for analysis, however, ICP-AES
can also be effectively used.

The focus of exploration is no longer just on gold. There is a need to be able to
accurately quantify base metals and other commodity elements of value at higher
concentrations. ALS Chemex has the experience and a range of procedures to
meet these requirements.
The Evaluation of Ores & High Grade Materials
While analytical methods for geochemical exploration are optimized for low detection limits, the assays for evaluation
of ores and high grade materials are optimized for accuracy and precision at high concentrations. The methods
described in this section are suitable for most ores and high grade materials. Depending on the purpose of the
analytical results, concentrations greater than 15%-20% may require the use of more expensive methods, such as
titrimetric and gravimetric analysis, in order to achieve the maximum accuracy. Please contact your nearest ALSChemex laboratory should you require this type of analysis.

Mineralogical Assays
Evaluation of copper prospects often involves the need to know more about the mineral forms the copper is present
in. This information can be obtained by leaching samples with different chemicals. For example, to determine a
sample’s tenorite (oxide copper) content, citric acid can be used to leach the mineral from the matrix. Malachite,
azurite, chrysocolla and portions of the cuprite, in addition to tenorite can be leached using sulfuric acid. The results
of the preceding are often referred to as “acid soluble” copper and “non-sulde” copper. Another leaching agent
commonly used for copper mineral selection is cyanide which will give the chalcocite, bornite and a portion of the
chalcopyrite contents of the sample. The mineral forms listed as being solubilized in each leach are meant as a
guide only and there can be quite different outcomes depending on the sample matrix and specic mineralogy. For
each project and mineral type, adjustments to leach conditions and chemicals will be needed to ensure the correct
mineral types are being targeted.
A few of the leaches available from ALS Chemex for this type of work are listed below. Custom methods using
different leaches and conditions are available on request.

Selective Leach Geochemistry
Mineral exploration is moving into mature terrain and the best potential often lies beneath deep overburden. Subtle
anomalies can be detected using conventional analytical methods; however, these types of strong acid digestions
are less selective and the bulk chemistry of the overburden may mask the presence of trace elements. There are a
variety of weaker leaches that are effective in selectively dissolving specic components of the sample.
ALS Chemex offers a wide variety of selective leaches to allow our clients to select the leach which is most applicable
to their geological and surcial geochemical eld environment. We offer non-proprietary methods including, but not
limited to, cold and hot hydroxylamine hydrochloride and sodium pyrophosphate leaches. We also offer the proprietary
leach method Mobile Metal Ion (MMI) technology. In all cases instrumental analysis is carried out using ICP-MS.
Contact an ALS Chemex representative who can discuss your needs for your particular exploration projects.
MMI - Mobile Metal Ion Leaches
MMI analysis is performed by ALS Chemex under a licensing arrangement with Wamtech Pty Ltd, owners of the
technology. In the right geological environment the MMI Process enables the detection of deeply buried mineralizationusing a surface soil medium, through the dissolution and subsequent measurement of mobile metal ions, which are
loosely attached to the surface soil particles. MMI uses proprietary leach reagents suitable for the extraction of the
target elements.

Cold Hydroxylamine Hydrochloride
The cold hydroxylamine leach has been used extensively by explorationists because it is selective for manganese
oxides, long known to be powerful scavengers of heavy metals of geochemical signicance. Manganese forms
several oxidation states and exists in a variety of amorphous and crystalline forms. As a result, manganese oxidehas an extraordinarily high cation exchange capacity, accommodating many different trace elements on its surfaces.
This leach does not dissolve crystalline iron oxides but does dissolve very small amounts of amorphous hydrous
iron oxide.
Hot Hydroxylamine Hydrochloride
The hot hydroxylamine leach, which combines a higher concentration of hydroxylamine with elevated temperature
(60°C) and a reducing acid environment, is capable of effectively dissolving amorphous hydrous iron oxide while
leaving crystalline iron oxide substantially intact (typically

Acid Generation Potential Evaluation
Natural oxidation of sulde minerals in rocks and tailings by a combination of chemical and biological weathering
can result in the formation of sulfuric acid, thus lowering pH and causing increased levels of dissolved trace metals.
The rate of acid generation is extremely complex and is affected by such variables as pH, temperature, humidity,
oxygenation, particle size and sulde mineral species. In addition, the rate of acid generation is accelerated by
certain bacterial species such as Thiobacillus ferrooxidans. The degree of bacterial action depends in turn upon
such factors as pH, population density and growth, and nutrient concentrations.
Acid-generating minerals include the various mineral forms of pyrite as well as other common sulde minerals such
as arsenopyrite and chalcopyrite. However, other species in the waste rock frequently include alkaline minerals
such as calcite as well. These alkaline minerals can effectively neutralize acid-generating and alkaline materials,
both in the short term and over extended periods of time. Depending on the amount of alkaline material present, the
sulfuric acid may be partially or completely neutralized. If the production of sulfuric acid exceeds its neutralization
by alkaline materials, then the result is acid rock drainage.
ALS Chemex offers different methods to assess the acid generating potential of your waste piles, both in the short
term (Static Test) and over extended periods of time (Humidity Cells).
Static Test Using Acid-Base Accounting
Our acid rock drainage static test has been designed to measure the balance between potentially acid-generating
minerals (maximum potential acidity) and acid-neutralizing minerals (neutralization potential) in a sample. This
procedure, known as Acid-Base Accounting (ABA), yields a gure known as Net Neutralization Potential (NNP),
which determines whether a particular sample will theoretically generate acidity over time. Depending on the
parameters included, there are different static test options.
