Remote projects require a high degree of support and logistical consideration. Where project location creates a barrier to shipping large samples to the laboratory, or where the sample volume is such that it is more economical to process or pre-process samples on-site, ALS Geochemistry offers placement of customized, carefully designed mobile sample preparation facilities for maximum efficiency and convenience. Mobile solutions are available via experienced ALS manufacturing teams in Johannesburg, South Africa and Perth, Western Australia.

ALS Mobile Sample Preparation solutions consist of either a standard 10x20 foot or 10x40 foot shipping container which is converted into a mobile sample preparation facility. An ALS Geochemistry supervisor will be on-site for the installation of the facility after a suitable small concrete pad (or alternative site preparation) has been constructed.

Mobile sample preparation facilities can be easily expanded into a full service on-site analytical laboratory through partnership with ALS Mine Site Services.

individual Sample Preparation Procedures

Splitting

After crushing, some samples may require splitting into representative sub-samples. In many locations automated rotary splitters can be attached to crushers to produce demonstrably superior precision in sub-sample analyses.

Pulverizing

While larger pulps offer better sub-sample representation and are required for metallic screen assays, 250g pulps are routine for low-grade or non-mineralized rock. All pulverizing procedures make use of flying disk or ring and puck style low-chrome steel grinding mills unless otherwise specified. Please enquire if you are interested in non-metallic pulverization media such as agate, tungsten carbide or zirconia.

Crushing

Jaw crushers may be used to reduce sample particle size prior to pulverization. Very fine crushing may be desirable when nugget effect and sample representivity is a concern. Other nominal sizes and fineness options are available on request.

The following procedures can be used either separately or combined in a package in order to meet specific needs regarding sample size and composition. Most of these procedures are charged at a rate that is based on sample weight.

Drying

Drying charges are only applied to samples that are excessively wet. Local laboratory managers will determine the applicability of such charges in consultation with the client when the samples are received.

Specific Gravity (SG) and Bulk Density (BD) of ores are often under-characterized in the determination of tonnage and grade of a deposit. Incorrect assumptions or inadequate characterization of these basic rock properties can lead to gross errors in deposit tonnage. SG is determined by weighing a sample in air and in water, and it is reported as a ratio between the density of the sample and the density of water. BD is the density of a material in weight per unit volume, and it is determined by the weight of a sample and the volume of water the sample displaces. Calculations for SG and BD are corrected for air temperature and the density of the wax coating, if a wax coating is used. Solvents other than water are available in some locations; please enquire for more information.

These procedures may be used when specialized preparation or sample compositing is required. An hourly labour charge may apply to time-intensive projects.

Gold in rocks, Drill Core and Chip Samples

Selection of the best fire assay method for the accurate determination of total gold content in a sample is highly dependent on the nature of the sample matrix, the grain size and distribution of the gold and the objective of the analytical result. A wide variety of minerals and metals in moderate to high concentrations (such as chromite, base metal sulfides and oxides, selenides, and tellurides) can interfere with the fire assay process, generally leading to low precious metal recoveries. ALS Geochemistry uses an optimal flux recipe and rigorous quality control program to handle all but the highest concentrations of these problem materials. With prior knowledge of the presence of these minerals and metals, ALS Geochemistry can further modify the flux constituents to improve recoveries.

* 1 oz/ton = 34.2857 ppm

When samples contain very high grade or coarse gold occurrences, the screen metallic procedure is recommended to help avoid over- or under-estimating gold grades. Custom method triggers can be set up for your project such that gold over a certain concentration will automatically be re-run using a higher-grade method, including screen metallics. Client services at ALS Geochemistry can help you customize a gold assay program to meet your project needs.

* 1 oz/ton = 34.2857 ppm** Other screen sizes may be available - please contact your local office for details.

Cyanide leach for Stream Sediments

Bulk Leach Extractable Gold (BLEG) or cyanide leach procedures are used where cyanide extraction from a very large stream sediment sample (up to 3kg) can sometimes detect small gold anomalies that otherwise would go unnoticed. Prices for cyanide leaching of samples greater than 1kg by quotation.

Gold and Multi-element Aqua regia Packages

Our gold in soils and sediments methods may be combined with multi-element packages to provide a complete, cost effective and meaningful data set for geologists and geochemists.

Gold in Soils and Stream Sediments

Aqua regia Digestion

The determination of gold in soils and stream sediments by aqua regia digestion offers very low detection limits, making it an attractive option for geochemical orientation surveys. Aqua regia effectively dissolves both native gold as well as gold bound in sulfide ore minerals. Depending on the soil composition, gold determined by this method may or may not match recovery from fire assay methods.

Gold Cyanidation In mining and exploration applications, cyanide leach tests are used to establish the potential cyanide extraction efficiency for gold and silver. Various temperature and cyanide concentration configurations are available; please contact client services for more information. Specific to gold, the preg-rob leach test can identify the tendency of certain ores to re-adsorb gold from the cyanide solution, causing lower recoveries than anticipated. Graphite and certain sulfide minerals such as chalcopyrite can cause preg-robbing behavior.

Gold in solution in cyanide liquor or captured on activated carbon may be determined for metallurgical purposes.

Precious Metals in Concentrates and bullion

Weak Acid Leach

Exploration geochemistry utilizes trends and patterns in trace element distribution as indicators of concealed mineralization deep below the surface or at a great distance from the sample location. The trace elements that circulate in the overburden are often trapped on the surfaces of reactive minerals or weakly bound in weathering products, and they may be further transported by plants and groundwater acting to dissolve the secondary minerals hosting them.

There are a wide variety of partial leaches available that are designed to target different minerals and particle size fractions in soils and sediments, and novel sample mediums like surface water and vegetation can be used to vector towards blind deposits. ALS Geochemistry offers a number of these generative exploration methods, detailed in the next four pages.

Guide to Partial leaches for Soils

This graphic can be used to help determine which leaches will target particular mineral fractions in soils. The amount of a particular element taken into solution by these digestion methods will depend both on the sample matrix and the leach chemistry, and this information can only be used as a general guide for interpreting partial leach results.

The aqua regia digestion, in combination with sophisticated software and careful analysis by ICP-MS and ICP-AES, provides extremely low detection limits useful for exploration in soils or sediments requiring ultra-trace analytical sensitivity. Alternatively, a weak acid digestion using 1:1 nitric to hydrochloric acids at room temperature may be used for more selective digestion of oxyhydroxide minerals.

These methods can also be done on the clay fraction of soils; the preparation procedure for clay separation is detailed on page 7 in the Sample Preparation section. Minimum sample size is 1g.

ionic leach Ionic Leach is a static sodium cyanide leach using the chelating agents ammonium chloride, citric acid and EDTA with the leachant buffered at an alkaline pH of 8.5. This innovative leach technique is designed for near surface soils; sample handling is minimal and the material is digested as collected with no drying or sieving, so there is very little opportunity to lose or introduce elements during the partial leach process. It is designed to enhance the potential to detect and resolve geochemical anomalies for a range of commodity elements.

The procedure selectively solubilizes metal ions that have been leached from the primary source, migrated, and then redeposited near the surface. This approach is combined with advancements in sample introduction and analytical instrumentation to achieve the very low detection limits needed to produce high signal to noise ratios in partial leach surveys. Compared to other partial extraction techniques, Ionic Leach preferentially attacks weakly adsorbed metal ions, metals associated with carbonate minerals, and to some extent, metals associated with amorphous Mn and Fe oxyhydroxides. Most partial leaches are performed in an acidic medium, whereas the Ionic Leach method is alkaline. The presence of EDTA and cyanide means that metals, especially Au and Ag, are strongly complexed and stay in solution prior to analysis, preventing readsorption to undigested mineral surfaces.

Ionic Leach is particularly useful for the resolution of subtle anomalies over blind mineralization. It has been found that where mobile metal ions have been added to a soil horizon from deeply buried mineralization, aqua regia may obscure key geochemical signatures as it can be too aggressive. ALS Geochemistry highly recommends an initial orientation program to demonstrate the advantages of Ionic Leach over a traditional aqua regia digestion in a particular geological setting.

Minimum sample size is 50g (wet weight) of soil for Ionic Leach. Specially prepared vegetation samples may be leached at a 5g sample size.

other Selective leaches In addition to Ionic Leach, ALS Geochemistry offers a wide variety of other partial leaches so that our clients can select the leach that is most applicable to the geochemical environment being sampled. The different leaches are designed to target different parts of a soil or sediment sample. Leaches can be done individually or sequentially to best suit project needs. The minimum sample size for each leach or for any combination in sequence is 1g.

De-ionized water (Me-MS03)

The water soluble fraction contains the most weakly bound ions. This leach is not buffered and subject to pH variability during the leaching process due to buffering of the leach by the sample mineralogy.

Ammonium Acetate (Me-MS04)

Slightly stronger than a water wash, the ammonium acetate leach targets the most weakly bound ions and can be used in sequential extractions prior to stronger leaches. This buffered leach is used to extract exchangeable ions and carbonates.

Cold hydroxylamine-hydrochloride (Me-MS05)

The cold hydroxylamine-HCl 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 significance. Manganese forms several oxidation states and exists in a variety of amorphous and crystalline forms. As a result, manganese oxide has 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 (Me-MS06)

The hot hydroxylamine-HCl leach, which combines a higher concentration of hydroxylamine with elevated temperature (60C) and a reducing acid environment, is capable of effectively dissolving amorphous hydrous iron oxide while leaving crystalline iron oxide substantially intact (typically < 1% dissolution). As amorphous hydrous iron oxide is a much more effective scavenger than crystalline forms of iron oxide, this leach can be quite informative about metal ion mobility.

Sodium Pyrophosphate (Me-MS07)

Organic matter in soils and sediments is capable of forming chelation complexes with metals. A solution of neutral (pH 7) sodium pyrophosphate liberates these organically-bound heavy metals. Variations in the concentrations of organically-bound metals such as copper, zinc, cobalt, nickel, iron and aluminum have been used as indications of buried mineral deposits. Extraction with pyrophosphate does not attack sulfides, nor does it dissolve significant amounts of amorphous iron oxides.

hydrogeochemistry high resolution iCP-MS on natural waters

Ground and surface waters are important media for the geochemical exploration of many different styles of mineralization. Trace metal analysis in water can reveal mineralization-related anomalies in areas where soil sampling is difficult or impossible, such as swampy terrain or desert. ALS Geochemistry offers a highly attractive analytical package, which includes everything required to carry out a hydrogeochemical survey: acid-washed, pre-labeled 250mL sample bottle pairs; ultrapure nitric acid in pre-measured ampoules; disposable 45 micron filters and syringes for field filtration; bottles of de-ionized water for field blanks; and coolers with optional ice packs for sample shipping and transportation.

Please note this method is not suitable for surface or groundwater with high dissolved solids or metals content, mine effluent, or brackish/salt water. The samples must be submitted in the bottles supplied with the package. For all other types of water sample analysis, please contact your local lab for options.

biogeochemistry Plants may be viewed as large-scale geochemical sampling devices, with root systems that can selectively adsorb elements from a large volume of soil, groundwater and even bedrock. Typically, the relationship between the chemistry of a plant and that of the soil the plant grows in isnt one-to-one due to biological effects.

Due to permit requirements, vegetation samples are not available for return to the client.

Ultra trace level Methods Aqua regia Digestion for Drill Core and rocks

Method selection can be key to achieving exploration success. Sample type, target commodity, and pathfinder elements should all be considered when selecting the most appropriate method for your project.

Aqua regia readily dissolves many sulfide, oxide and carbonate minerals quantitatively while leaving silicates and resistive oxides untouched. Many volatile pathfinder elements, particularly mercury, are preserved during digestion. These considerations make aqua regia an excellent exploration tool for various deposit types that involve gold, silver and base metals hosted in sulfide and carbonate minerals.

Native metals such as gold and silver may not be representatively characterized by the small sample sizes used in these methods (nugget effect), and some refractory minerals and elements such as molybdenum are not brought into solution in aqua regia. In these cases, fire assay may be used in combination with ME-MS41, or a four acid digestion may be preferable. Please contact your nearest lab with any questions.

Ultra trace level Methods four Acid Digestion for Drill Core and rocks

Four acid digestion quantitatively dissolves nearly all minerals in the majority of geological materials. However, it may sometimes be necessary to use even stronger dissolution techniques such as fusions in order to achieve fully quantitative results for refractory minerals. These may include barite, rare earth oxides, columbite-tantalite, and tin and tungsten minerals.

Four acid digestion can also volatilize certain exploration pathfinder elements, in particular mercury. Mercury may be added to the package at a special price detailed below, or a custom suite of elements can be added using the single-element aqua regia method on the opposite page as well. Four acid digestions are not recommended for gold analysis; the fire assay methods described on page 10 may be paired with ME-MS61 for exploration purposes.

individual and Miscellaneous Methods

halogens

Elemental analysis of the halide minerals containing chlorine and fluorine require specific instrumentation and special fusions or digestions that will completely dissolve and retain the elements in solution. For bromine and iodine, solid sampling by neutron activation must be used.


* When F and Cl are determined together by Ion Chromatography the price per sample is $27.50.

Mercury

Mercury poses special analytical challenges and may be partially or completely volatilized by high temperature digestions. Aqua regia is the digestion of choice for a range of concentrations; ICP-MS and ICP-AES methods have superseded the traditional cold vapor-AAS instrumentation, but they are still available if desired.

Geochronology

Radiometric dating determines the age of a particular mineral or rock by the measurement of an isotope and its radiogenic decay product. Knowing the age of certain lithologies associated with ore mineralization has wide-ranging application to exploration on established projects. These ages, in combination with other exploration techniques, may be used to refine the deposit model and vector towards potential new ore bodies.

Mineral Specific Geochronology

isotopic Analysis Mineral separation or thin section mounting is required for many of these methods. If the description indicates sample prep is not included, ALS Geochemistry can help you source high quality mineral separation and thin section preparation as necessary; please enquire.

Stable isotopes

Many important parameters of mineralizing fluids may be determined from stable isotope ratios including fluid temperature, geographic origin, and redox state. The isotopic alteration halo may extend beyond visible mineralogy changes, creating a bigger deposit footprint and allowing for more sophisticated exploration vectoring towards ores.

whole rock Analysis The nature of lithophile elements and the matrices in which they occur require fusion methods for complete dissolution. Both X-Ray Fluorescence (XRF) and ICP-AES instrument finishes can be used effectively for the major rock-forming elements when following a fusion.

These methods are suitable for generic crustal rocks and drill core that are not mineralized. Specific commodities such as iron ore, bauxite, and base metal sulfides should be analyzed with packages designed for those sample types. Please see the Ores & Commodities section starting on page 26 for more whole rock analysis options.

*Other elements are available on request. Please enquire.

A lithium borate fusion of the sample prior to acid dissolution and ICP-MS analysis provides the most quantitative analysis approach for a broad suite of trace elements. This technique solubilizes most mineral species, including those that are highly refractory. Options for adding the whole rock elements from an ICP-AES analysis from the same fusion or base metals from a separate four acid digestion are available.

lithogeochemistry Analyses related to lithogeochemistry, alteration minerals, and trace element mobility are important tools for understanding ore-forming geological environments. Managing and interpreting large datasets generated by lithogeochemical techniques, while traditionally challenging, has been greatly simplified thanks to powerful software tools now available to geologists and geochemists.

No single analytical method is able to encompass the full range of elements required for effective lithogeochemical investigation. To this end, ALS Geochemistry offers two analytical packages that are designed to provide comprehensive information for these studies using the most appropriate techniques for every element; essentially, complete rock characterization.

Complete Characterization Package

By combining a number of methods into one cost effective package, a complete sample characterization is obtained. This package combines the whole rock package ME-ICP06 plus carbon and sulfur by combustion furnace (ME-IR08) to quantify the major elements in a sample. Trace elements including the full rare earth element suites are reported from three digestions with either ICP-AES or ICP-MS finish: a lithium borate fusion for the resistive elements (ME-MS81), a four acid digestion for the base metals (ME-4ACD81) and an aqua regia digestion for the volatile gold related trace elements (ME-MS42). Gold is analyzed separately see page 10 for methods.

This package is suitable only for unmineralized samples. Minimum sample size is 10g.

Procedures for the evaluation of ores and high grade materials are optimized for accuracy, precision and recovery of the target element. No single dissolution or analytical method is suitable for all cases, and ALS Geochemistry provides a wide variety of procedures so the preferred method can be selected. Choices include acid digestions with either ICP-AES or AAS finish; XRF determination for resistive elements and minerals that are difficult to decompose or retain in stable solutions at high concentrations; and classical volumetric methods for very high grade commodities.

These methods may be triggered automatically as over-range analyses added to multi-element geochemistry packages on request. Many other procedures are available; please contact ALS Geochemistry staff for information.

Aqua regia Digestion with iCP-AeS or AAS finish

Aqua regia is a powerful solvent for sulfides, which dissolves Ag and base metals but may not completely dissolve more resistive elements. Minimum sample weight 0.5g

base Metals in Massive Sulfides

Assay determinations in massive sulfides present some specific challenges. ALS Geochemistry is able to offer a number of approaches including a strongly oxidizing acid digestion, a sodium peroxide fusion and an XRF package.

oxidizing Acid Digestion with iCP-AeS finish

This procedure is equivalent to the ICPORE method previously offered by OMAC Laboratories. The sample is subjected to a highly oxidizing attack with HNO3 , KClO4 and HBr and the final solution in dilute aqua regia is determined by ICP-AES.

Sodium Peroxide fusion with iCP-AeS finish

Sodium peroxide fusions are effective for the decomposition of sulfides, arsenides and many refractory minerals such as chromite, rutile, ilmenite and titanite. It is the method of choice for nickel sulfide deposits.


oxidizing fusion with Xrf finish

High sulfide samples can be analyzed by XRF following a lithium borate fusion with the addition of a strong oxidizing agent. The following method is suitable for a wide range of elements in sulfide ores, and other elements are available to report on request please enquire.

* A method for sulfide concentrates, ME-XRF15c, is also available.

A full range of geochemical, metallurgical and environmental testing with specialized expertise in copper and gold ores.

With state-of-the-art equipment and scalable analytical processing capacity for more than 2,000 specialty copper leaches and 6,000 fire assay samples per day, the establishment of the Santiago Mineral Services Center demonstrates ALSs long term commitment to the South American mining sector.

The ALS Santiago Mineral Services Center is not just about capacity it provides for a seamless transition from exploration to metallurgical process development testwork. A coordinated team, working with industry to ensure that knowledge is shared and processes are optimized.

Evaluation of copper prospects requires knowledge of mineralogy and mineral solubility for metallurgical considerations. The isolation of oxide/carbonate, secondary chalcocite and primary sulfide minerals from total copper is useful in determining leachability of copper in a deposit. This information can be obtained by sequential leaching of the sample.

The ALS Santiago Mineral Services Center houses a purpose built copper leaching laboratory with the capability to undertake specialty copper leaches.

New and existing copper deposits are increasingly challenging to develop and mine due to lower grades and complex mixed ore types. Early geometallurgical investigation of the potential ore body is crucial for informed decision-making on the economic viability of many copper projects.

Mineral Selective Methods and Sequential leaches

Oxidized copper minerals such as malachite, azurite, chrysocolla and portions of cuprite and tenorite can be leached using sulfuric acid to identify the acid soluble content in copper ores. Cyanide leach will dissolve the oxides (with the exception of chrysocolla, which is only partially digested), secondary sulfides like chalcocite and covellite, and bornite. The chalcopyrite content in ores will remain largely undissolved by either sulfuric acid or cyanide leach. These mineral-selective leaches and others may be run in sequence on a single sample to semi-quantitatively identify the potential recovery by various copper ore processing methods. The actual amount of each mineral dissolved in each leach may vary depending on the sample mineralogy, grain size, and other physical characteristics.

ALS Geochemistry provides custom methods using different leach conditions upon request, including some uncommon leach chemistries with specific applications not listed below.

total Copper Methods

Aqua regia is an effective solvent for copper oxides and sulfides, but copper occurring with other commodities like molybdenum can be analyzed by four acid digestion for consistency across data sets.

Xrf Analysis for iron ore

X-Ray Fluorescence (XRF) is the method of choice for the analysis of oxide iron ores. The lithium borate fusion technique, coupled with XRF, offers a robust and repeatable method consistent with industry requirements. The relatively low flux to sample ratio offers good sensitivity for the majority of elements and creates a matrix which is not subject to particle size effects. With very few spectral interferences and high instrument stability, the XRF method delivers highly accurate and p
