5 the minerals industry Cutting-edge technology and capabilities ALS is constantly evaluating new instrumentation, technology and tools for our commercial operations and our on-site services if it improves efficiency, reduces costs and adds value, we re already working on it. Control Alerts Dual View ICP-AES Microwave Plasma (MP-AES) ALS Webtrieve offers a real-time analysis tool for measurements critical to operation, such as mill feed samples and environmental water monitoring. Control limits are set by you, specific to an analyte and sample stream. Whenever a measurement falls out of bounds the tool alerts one or more responsible persons by , SMS or both. Immediate response to control failures is now possible without tediously checking in at every time point. A new generation of ICP-AES instruments is capable of analysing both concentrated levels of commodity elements and trace level impurities or environmental hazards on the same machine with a simple plug n play component switch. Now, more environmental analysis monitoring is possible for less capex/opex expense. ALS has developed many on-site methods specifically for this instrument s capabilities. The MP-AES boasts many of the capabilities of ICP-AES and AAS, but runs on an air compressor instead of an external argon or acetylene gas canister. With significant cost savings and reduced risk for remote sites, ALS has been developing methods for this instrument since 2012 with an eye to installation in difficult geographies.

6 The Next Lithium Boom... Your Trusted Analysis Provider With electric vehicles and solar power generation poised to transform our world, the rare commodity critical to high-tech batteries lithium is seeing a renewed surge of interest from the global market. Rigorous quality control on lithium assays is crucial to bring low-cost, high-grade Li deposits to successful production but out-of-date analytical knowledge as a result of the long cyclical nature of the lithium market can present pitfalls for geologists and engineers building resource estimates. ALS is the premier service provider in lithium analysis, with technical expertise in every region where lithium deposits are common. Our methods are tailored to 3 broad classes of lithium deposit which each have their own unique geological and chemical considerations. PEGMATITE AND JADARITE These deposits host lithium in silicate minerals, along with a wide variety of economic accessory elements. Many pegmatite minerals are very resistive to acid digestions, which could under-report elemental contents if used. Sodium peroxide fusion is the digestion method of choice for this geological setting. LITHIUM BRINES Brines pose a particular analytical challenge when looking at trace element content along with Li and others in higher concentration. ALS offers methods tailored specifically to lithium brines for elemental analysis, as well as routine brine parameters like ph, conductivity, total dissolved solids and more. SEDIMENTARY DEPOSITS Clays, carbonates and sedimentary rocks enriched in Li are readily dissolved in acid digestions, but different acid mixtures and analytical techniques may produce differing Li contents due to geochemical complexity. Aqua regia digestions are usually recommended. Speak to your local lab for more information on ALS s expert lithium analysis capabilities.

9 aisiris Expert Hyperspectral Interpretation Identifying alteration minerals, particularly clays, can be challenging during core logging. Spectral mineralogy, the identification of minerals in geological materials using visible and infrared light, is a powerful tool available to geologists for improved core logs and better field decision-making in exploration and mining settings. The major hurdle in implementing a routine spectral analysis program is interpreting large volumes of raw spectral data and integrating it into the workflow. To resolve these challenges, ALS has partnered with AusSpec International to provide our clients access to aisiris (Spectral InfraRed Interpretation System). This program rapidly processes raw spectra and outputs mineral assemblages and key spectral parameters in a database-ready format, enabling quick assessment of the relationships between alteration and mineralisation by project geologists. Access to the aisiris TM App is included, which plots results against spatial data for quick assessment. Turnaround time including a TerraSpec 4 HR scan is typically 2-5 days, ensuring this crucial data set is in your hands for timely field decision-making.

OA-GRA Specific Gravity on pulps using pycnometer Reported as a ratio. OA-GRA08b Bulk Density by water displacement g/cm 3 OA-GRA Bulk Density after wax coating (wax removal not included) g/cm 3 OA-GRA09a Miscellaneous Procedures DESCRIPTION APPLICATION CODE PRICE PER SAMPLE ($) Compositing of two or more samples. May be done by volume/core length (CMP-21) or by weight (CMP-22). Specific gravity and bulk density of ores are important parameters that are often undercharacterised in the determination of grade and tonnage of deposits. Incorrect assumptions or inadequate characterisation 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 BD are corrected for water 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 specialised preparation or sample compositing is required. An hourly labour charge may apply to time-intensive projects. As requested. CMP-21 CMP-22 Clean crushers with barren material after every sample. As required.

While microscopic flakes of gold can appear as isolated anomalies in surficial sediments, subtle variation in background concentrations may act as a better indicator of gold mineralisation in the subsurface, particularly in areas of transported cover. Super trace detection limits ensure that analytical precision is optimal for concentrations at crustal abundance or lower, allowing geologists to establish robust geochemical backgrounds for gold and associated pathfinder elements. Large sample aliquots are key to maintaining representivity and reproducibility of results due to the pronounced nugget effect seen in gold analysis, even at very low levels. Aqua regia and cyanide are the most common solvents in use for gold analysis. Although cyanide methods can achieve lower detection limits than aqua regia due to chemical interactions inside the ICP-MS, they are more susceptible to preg robbing behavior by organic matter and sulphide minerals. Sample composition should be taken into account when choosing a digestion technique. ALS offers the lowest detection limits in the industry for gold in soils and sediments by both standard digestion methods using our innovative super trace analytical methodology. AuME-ST43 (25g Au & multi-element) AuME-ST44 (50g Au & multi-element) Full multi-element geochemical suites may be read from the same digest solution as our aqua regia and ICP-MS super trace gold methods.

Se-MS Clay Separation ALS remains committed to method development for new analytical platforms while tackling long-standing issues in analytical geochemistry. Every method listed in the next four pages of this schedule involves our innovative methodology for super trace analysis on the ICP-MS in some aspect, as well as making use of new instrumentation and fresh ideas from our expert technical team. 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 super trace analytical sensitivity. Analytical background is minimised in aqua regia because of its simple chemistry, allowing better delineation of true anomalies. A weak acid digestion using 1:1 nitric to hydrochloric acids at room temperature may also be used. Add-on Packages for ME-MS41L and ME-MS41W The rare earth elements and lead isotope concentrations analysed on the same run as the multielement package add a new dimension to super trace data. In soils and sediments the REEs may be useful exploration indicators despite reflecting only the lightly-bound labile component, and lead isotopic signatures can be used in fingerprinting certain units or hydrothermal fluids. Super Trace Selenium in Soils With ultra-clean disposable digestion vessels and the ICP-MS collision cell tuned specifically for Se, we can achieve a super trace detection limit without external sensitivity tweaks. Selenium at this level holds information for exploration geochemistry, environmental baselines, and lithomapping in areas of thick cover. ALS offers a rapid, high-quality clay size fraction separation on screened soils. The clay fraction in soils acts as a trap for labile elements migrating to the surface environment from depth, and may be used to enhance subtle geochemical signals DESCRIPTION CODE PRICE PER SAMPLE ($) Separation of the -10 micron fraction from soils.

Average ash yields are 2-4% for species commonly used in exploration surveys. VEG-ASH Sample pre-treatment for super trace halogens analysis. Required for soils and un-ashed vegetation. HAL-PREP ANALYTES & RANGES (ppm) DESCRIPTION CODE PRICE PER SAMPLE ($) F 0.05 Cl 0.1 De-ionised water leach with ICP-MS & ion Br 0.02 I chromatograph analysis. Ionic Leach The halogen elements fluorine, chlorine, bromine, and iodine hold significant promise in exploration geochemistry, since many precious and base metals are transported through the crust as halide complexes in hydrothermal fluids. Case studies in Kazakhstan and Canada have shown distinct halogen anomalies in soil and vegetation over known mineralisation, but until now, the utility of halogen geochemistry in exploration was severely limited by instrument technology and chemistry roadblocks. ALS chemists have developed the first complete super trace halogens package for exploration in soils and sediments available to industry. This method uses careful sample pre-treatment and a gentle de-ionised water leach to retain the labile portion of the halogens in solution, coupled with dual ICP-MS and ion chromatograph measurements. Any surficial sample medium may be analysed - soils, vegetation or water - and the pre-treatment is customised to the medium for best results. Please contact your nearest ALS office to discuss specific sample weight requirements and the best course of action for your particular project. Sample Pre-treatment for Super Trace Halogen Analysis Super Trace Halogens in Soil, Vegetation and Water ME-HAL 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 limited to minimise opportunity for super trace contamination. It is designed to enhance the potential to detect and resolve geochemical anomalies for a range of commodity elements. Minimum sample size is 50g (wet weight) of soil for Ionic Leach. Specially prepared vegetation samples may be leached at a 5g sample size.

Biogeochemistry Trace metal analysis in ground and surface waters can reveal mineralisation-related anomalies in areas where traditional soil sampling is difficult or impossible, such as swampy terrain, desert, and agricultural disturbance. Using the latest generation of collision-cell equipped ICP-MS, ALS offers a reliable and cost-effective water analysis package with optional anions by ion chromatography and a full suite of physical parameters. Sampling kits may be purchased in some locations, please enquire. Plants may be viewed as large-scale geochemical sampling devices, with root systems that can selectively absorb elements from a large volume of soil, groundwater, and even bedrock. Careful selection of plant species is important as biological effects control geochemical response.

These methods offer a full pathfinder element suite at very low detection limits and can be further used as a proxy for mineralogy and lithology, when lithogeochemical analysis is not possible across an entire drilling program. Four acid methods can also be used effectively in areas of thick regolith for bedrock lithomapping. ALS has developed a super trace package suitable for greenfield exploration and regional drilling, with elements such as As, Sb, Se and Tl showing anomalous patterns at levels previously unrecognisable due to technical limitations. Add-on Packages for ME-MS61L The rare earth elements and lead isotope concentrations analysed on the same run as the multi-element package add a new dimension to super trace data. Four acid digestion will not fully dissolve resistive rare earth oxides, but the information in this suite of elements can be very useful in exploration targeting. Lead isotopic signatures can be used in fingerprinting certain units or distinguishing barren hydrothermal fluid events from ones related to mineralisation. Silicon, titanium and zirconium may be added to four acid methods for a more complete element suite. While four acid digestion does not fully dissolve all rock-forming minerals, it is often the only data set available across an entire project. The addition of these crucial lithogeochemical elements by portable XRF analysis on the sample pulp greatly increases the utility of four acid packages beyond the trace elements. pxrf SUPER TRACE ANALYSIS FOR ROCKS AND DRILL CORE 20

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 sulphide, 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 sulphide and carbonate minerals. Native metals such as gold and silver may not be representatively characterised 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.

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 volatilise 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.

29 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. LITHOGEOCHEMISTRY No single analytical method is able to encompass the full range of elements required for effective lithogeochemical investigation. To this end, ALS 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 characterisation. Complete Characterisation Package By combining a number of methods into one cost effective package, a complete sample characterisation is obtained. This package combines the whole rock package ME-ICP06 plus carbon and sulphur 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 analysed separately see page 13 for methods. This package is suitable only for unmineralised samples. Minimum sample size is 10g.

37 Acid-Base Accounting Procedures Acid-base accounting (ABA), also called static testing, calculates a net neutralisation potential (NNP) representing the ability of a body of rock to produce acid rock drainage or to consume free acid and neutralise it. The mineralogy of carbonates, sulphates, sulphides and other rock-forming minerals in the sample will affect the accuracy of the ABA prediction, so mineralogical knowledge of the sample is an important augmentation to the static ABA tests. ALS offers many combinations of ABA procedures. The packages listed below are those most commonly used. For a more detailed discussion of ABA methodology, please ask our client services team for more information.

ACID ROCK DRAINAGE TESTING Other Acid Rock Drainage Tests ALS can help you arrange a wide variety of sample preparation protocols, mineralogical identification, kinetic testing, water analysis, and more for environmental assessment purposes. Please enquire at your local lab for more information. Net Acid Generation Net Acid Generation (NAG) provides a quantitative estimation of the amount of acid that can be generated by mine waste rock or tailings where the NNP does not, provided the rock is acid-generating and not acid-neutralising. In order to analyse for metals in the leachate in addition to the NAG test, a full second leach must be performed and the procedure will be charged twice. DESCRIPTION CODE PRICE PER SAMPLE ($) Net Acid Generation (NAG) - Hydrogen peroxide is used to facilitate the rapid oxidation of sulphide. NAG is reported in kg H 2 SO 4 /tonne at ph 4.5 and ph 7.0.
