Qlab - online data platform and retrieval

Depending on the circumstances, studies may need to involve matrix equivalent samples taken through the entire method process, and not simply by using a reagent or water blank.

All our clients have access to our online data platform and retrieval. System called “QLab” (https://qlab.sgs.com) . The tool allows clients to track the status of their samples and access analytical data immediately using a secure retrieval system. It contains important information including job status, turn-around time, scheme/method, client specific quality control data and the results of your analyzes. With this information you can track your performance against the reference materials across the entire project. All results are reported electronically immediately upon completion. Reporting units can be specified as ppb, ppm, g/t, % or oz/tonne (as applicable). SGS will send a copy of all certificates and invoices in PDF format, via email, to the address you specify after which the documents will available in Qlab.

Tailored analysis across the value chain

How precise the analysis needs to be depends on your purpose and where you are in the value chain. For example, during early-stage exploration precision at low concentrations, sensitive and cost effectiveness are usually key - accuracy may not be as important. As a result, a method may be selected providing it has a reasonable threshold. On the other hand, in process of grade control situations accuracy and precision are critical and require commercial grade assays using high precision methodologies. Innovations and leadership SGS takes its role as a leading analytical service provider seriously. We invest in the technology, resources and innovation required to solve the most complex mining challenges. More detailed descriptions of the common analytes, grades and methods follow in this guide, with more information available at your local laboratory. An SGS customer service agent is always available to assist you with analytical technique selection. Contact us at naturalresources@sgs.com

Data turnaround Samples are processed at each SGS

this concept is varied, misused and often confusing. The lower limit (detection limit) is frequently used to market method capabilities but depending upon how this limit is validated and tested, this limit can be misleading. Method choice should not be exclusively selected based on the lower limit but must be well defined based on the circumstances. Statistical analysis must be used both to estimate and test the lower limit at a suitable confidence level. When selecting a method, it is important to consider: • What are the elements of interest and their concentration range? • What is the required precision at or near the concentration of the analyte of interest? • What is the mineral composition or source of my samples and will this affect the detection limit for the elements of interest?

SGS’s Centres of Excellence and major regional laboratories conform to standard requirements for ISO/IEC 17025 as per the published scopes of accreditation. SGS provides analytical services for every stage of your project including: • Exploration • Developmental Studies • Mine Production • Shipment • Trade • Mine Closure Analytical methods and limits At SGS, our laboratories take pride in our determination of method specific limits to ensure confidence in the results and that they are fit for purpose. In mineral analysis, the concept and application of detection limits is not defined universally nor is it governed by a regulated policy. The terminology used to describe

laboratory as promptly as possible. Sample batches requiring turnaround commitments outside contractual arrangements should be discussed with the appropriate laboratory customer services personnel.

Sample preparation (also referred to as sample reduction) is the process by which a sample is crushed, split and pulverized for analysis. This will almost always involve sub-sampling. The right sampling method will produce a sub- sample that is representative of the total sample. Good sample reduction practice is essential to obtaining meaningful and reliable analytical data. SGS is committed to providing dedicated sample preparation procedures at each of our locations. This involves technologically advanced equipment and, in most cases, physically separated sample processing areas for each sample type. The crushing and pulverizing options available are varied. Your choice can depend on the sample type and the mineral that hosts the element of interest within the sample matrix. Please consult with our technical personnel for the best possible option for your samples before starting an analytical program.

During sample reduction, there are many critical points where sample contamination can occur. One such area arises from the type of equipment used. Unfortunately, during sample reduction, contamination can never be avoided but processes are utilized to keep the level of contamination to a minimum. Contamination levels are dependent on sample hardness, the media/material of the crushing and pulverizing equipment and the wear state of this equipment. Contamination levels can be minimized by using the correct pulverizing bowl type for the project. Contamination in the sample preparation process is monitored by the insertion of known barren reference materials in the process.

Specific Gravity and Bulk Density Density is a fundamental rock property and can be defined a number of different ways. At SGS, we determine the specific gravity (SG) and bulk density (BD) of rocks, ores and aggregates. Specific gravity is the density of a material relative to water or air and is expressed as a dimensionless number. It is normally measured by the gas pycnometer method on pulp samples and amounts to the average SG of the mineral particles making up the rock or ore. It is an important parameter when developing metallurgical flowsheets or calculating the exact weight of a concentrate being shipped or stored. Density profiles of ores for dense media separation can be measured using heavy liquids. Bulk density is the average SG of the minerals comprising a rock plus the void space (from vugs, pores, etc.) and is measured by the water immersion method on fist sized rock samples or core. Samples are waxed if there is significant porosity. If the rock samples are competent waxing may not be necessary. Bulk density along with grade and volume is an extremely important parameter in calculating tonnages for Mineral Resource estimates or ore reserves, which are critical for economic evaluation of mineral deposits. Inadequate BD measurements are often at the root of errors in ore estimates with financial consequences for projects. Use high quality specific gravity, bulk density and grain size physical property data from SGS for robust Resource Estimate calculations and in developing mineral processing flow sheets.

Particle Size Analysis Particle size analysis is used to determine the size classification of tills, sediments or ores or to produce sized fractions for additional testing/analysis. SGS offers particle size analysis by wet screening, dry screening, a combination of both, or laser diffraction. Wet screening is preferable to dry screening for materials containing a high percentage of clays which tend to agglomerate and thus give erroneous dry screening results. Dry screen tests can be performed on a variety of materials, but the sample must be free flowing and the particles separated (i.e. unagglomerated). Often wet and dry methods are combined. Wet screening is performed to remove excessive fines then dry screening is performed to remove the oversize. Depending upon the nature of the material, dry screening, wet screening or a combination of both can be used. Laser diffraction is recommended for very fine grained samples, as it is capable of measuring particle sizes at very low limits (0.02 microns). Laser diffraction is suitable for use with both wet and dry samples.

Multi-Element Exploration ICP-OES and ICP-MS Packages Sample digestion

Drill-core and rock samples are generally analyzed by four acid or fusion digestion, with a multi-element finish. Where metal contents are high, samples can require further testing by other methods to ensure data is precise and accurate enough for regulatory reporting. Refer to the Ore-Grade Analysis section in this guide. Instrumentation ICP-OES and ICP-MS are accepted in the mineral exploration industry as rapid and cost- effective means of analysis, because they determine many elements at low detection limits and wide ranges. Other instruments that can be used for specific elements are AAS (Atomic Absorption Spectrophotometer) and Hydride AAS.

Sample digestion is the most important parameter to consider when choosing an analytical method. There are several types of digestion available, including:

• Aqua regia digestion • Four acid digestion • Sodium peroxide fusion • Lithium metaborate fusion

Typically, reconnaissance exploration grade samples (including regional soil samples) are analyzed by aqua regia digestion followed by a multi-element scan for base metals, trace and lithological elements.

Exploration Analysis

Aqua Regia Digestion Aqua regia is a combination of hydrochloric and nitric acids in a nominal 3:1 ratio. This is a weak digestion for geological samples that is appropriate for initial site exploration. Aqua regia will not break down silicate and other refractory minerals, providing partial results for most elements. ICP-OES, ICP-MS or a combination of both techniques can be used to measure these digests. A minimum 0.5g sample is required. Note: For samples containing high levels of organic materials or sulphide minerals, a modified aqua regia method (GE_ICP22B20 and/or GE_IMS22B20) is recommended.

Our global services provides a range of geochemical methods for finding and characterizing mineral deposits of every type. Discovering economically viable mineral deposits requires an expert understanding of the geochemical signatures and footprints of potential ore bodies. We lead the way in providing fit for purpose exploration geochemical analysis solutions that support exploration programs around the world. Utilizing a range of effective and proven methods, including our innovative Mobile Metal Ion (MMI™) technology, we can help you in the discovery of all categories of ore systems, including critical metals, industrial materials, base and precious metal deposits. We ensure that our solutions are tailored to your needs considering time, speed of analysis, cost and requirements of key stakeholders or disclosure legislation such as JORC, NI43-101 and SK-1300.

Multi-acid digests Multi-acid (Four acid) digestion is a very effective dissolution procedure for a large number of mineral species and is suitable for a wide range of elements. Multi-acid digestion uses a combination of HNO3 (nitric acid), HF (hydrofluoric acid), HClO4 (perchloric acid) and HCl (hydrochloric acid). Because hydrofluoric acid dissolves silicate minerals, these digestions are often referred to as “near-total digestions”. Requires a minimum sample weight of 0.5g. Lower and upper limit can vary slightly among SGS laboratories because some laboratories may not have access to high purity reagents and consumables. Please talk with your local laboratory manager to make sure you receive the reporting limits you need. Note: Refractory minerals such as oxides have limited solubility in multi-acid (Four acid) digestions. Often elements can precipitate or volatilize during digestion. These factors can compromise analytical results for Al, As, Ba, Cr, Hf, Mo, Mn, Nb, Pb, Sb, Se, Sn, Te, Th, Ti, Ta, U, W, Zr and rare earth elements in some sample types.

Fusion packages Fusion analyses result in complete dissolution of samples and are referred to as ‘total analyses.’ Fusions are typically more aggressive than acid digestion methods and are suitable for many refractory minerals such as chromite, ilmenite, spinel, cassiterite, lithium containing species and minerals of the tantalum-tungsten solid solution series. Sodium peroxide fusions Sodium peroxide is a strongly oxidizing basic flux that renders refractory minerals soluble. The sample is fused in a zirconium crucible and the temperature is kept relatively low, allowing the measurement of elements that are volatilized at the higher temperatures of lithium borate fusions. Samples can be measured using ICP-OES or a combination with ICP-MS. Some laboratories offer an alternate scheme using glassy carbon crucibles (GE_ICP91A50 and GE_ IMS91A50) to include Zr, Ag and Hf. Alternate dissolution using hydrochloric acid (GE_ ICP92A50 and GE_IMS92A50) is also available. Please contact your local customer service agent for the best approach for your samples. Requires a minimum sample weight of 0.2g.

Mobile Metal ION – MMI™ Soil Geochemistry SGS is the owner and sole provider of MMI™ Technology. We have over 20 years of experience with this technology, and we are the market leaders in providing a weak extraction of the mobile form of the ions residing in near surface soils. MMI™ is a world-renowned exploration tool repeatedly proven to find buried mineral deposits. MMI™ Technology is an innovative analytical process that uses a unique analysis of metals in soils and weathered materials. Target elements are extracted using weak solutions of organic and inorganic compounds rather than conventional aggressive acid-based digests. MMI™ solutions contain strong ligands, which detach and hold the metal ions that were loosely bound to soil particles by weak atomic forces. The extraction does not dissolve the bound forms of metal ions. Thus, metal ions in MMI solutions are the chemically active or ‘mobile’ component of the sample. Because these mobile, loosely bound complexes are in very low concentrations, elemental determinations are made by conventional or cell-based ICP-MS. There are many benefits to using MMI™ Technology for soil geochemistry, including: • Few false anomalies • Focused anomalies • Minimal nugget effects MMI Sample Collection Sample collection is the critical part of a soil geochemistry program. The MMI™ Technology has specific sampling protocols based on years of experience and research. In the absence of an orientation survey, samples must be taken at a constant depth (10-25 cm) below the organic-inorganic soil interface. There is no sample preparation or drying. The analysis is performed on a 50g sample and the extracted solution is analyzed via ICP-MS, providing determinations in the part per billion range. For detailed instructions of the MMI™ sampling protocols and orientation surveys, please visit sgs.com/geochemistry or contact us at naturalresources@sgs.com. Additional MMI Analyses The application of ICP-MS cell technology to the analysis of MMI samples results in lower detection limits due to the removal of interferences. This means better definition of anomalous targets, for example, in the exploration of nickel deposits, kimberlites and layered intrusions. Here, chromium, an important geological trace element, can be measured down to 1ppb. Similarly, for uranium exploration, low level vanadium (1ppb) is also important. These can be measured using an enhanced package, scheme code GE_MMIME. Additional elements such as S, B, Br, I, and Pb isotopes can also be measured as required.

Lithogeochemistry Lithogeochemical analysis is used for basic rock characterisation based on major, minor and trace element chemistry. It requires whole rock analytical methods to ensure that refractory minerals such as zircon and chromite are fully dissolved. Lithogeochemical analysis may be used in exploration programs for identification of different rock types that might occur in drill core or at outcrop, particularly when primary lithologies are obscured by subsequent alteration or metamorphic events. Lithogeochemical analysis is also used by geological surveys undertaking geological mapping projects, by researchers studying geological, geochemical and petrological processes and by oil companies requiring complete rock characterization for calibrating core responses to borehole sensors.
