4 Quality Assurance Quality Control At Bureau Veritas Minerals (BVM) our core product is analytical data. Over many years, we have invested heavily in proprietary software and staff development to ensure that you get the highest quality data. BVM has implemented a comprehensive quality management system meeting the requirements of ISO/IEC 17025:2005 and ISO 9001:2015 to ensure the necessary processes and oversight is in place to achieve this goal. ACCREDITATION Through the process of external auditing by recognized organizations our facilities maintain ISO registrations and accreditations. These registrations and accreditations provide independent verification that the management systems have been implemented and meet the requirements of the ISO standards. All BVM facilities are registered or are pending registration to ISO 9001:2015 under the Bureau Veritas corporate registration by the end of Additionally a number of analytical hubs have received ISO/IEC accreditation for specific laboratory procedures. AUDIT PROGRAM All BVM facilities are also internally audited against the above ISO standards by knowledgeable and trained personnel on a scheduled basis. PROFICIENCY TESTING PROGRAMS BVM laboratories routinely participate in national and international inter-laboratory comparison studies in order to independently assess individual laboratory performance for the test method(s) analyzed. QUALITY CONTROL Through comprehensive training BVM ensures that laboratory staff are competent to perform the analysis requested. All labs use validated methods to achieve accurate reproducible results with equipment that is maintained and calibrated to achieve the highest levels of performance. At all steps of sample handling the laboratory maintains traceability of samples through the use of barcode tracking and maintains detailed audit trails of the people and equipment used to perform analysis. IN SAMPLE PREPARATION As one of the most critical steps in the sample analysis process, BVM continually monitors the efficiency of crushing and pulverizing to ensure that a representative portion of each sample submitted is prepared. Sample duplicates are created and analyzed for all rock and drill core samples submitted. IN ANALYSIS In addition to routine calibration solutions the laboratory inserts reference materials, replicates and blanks into randomly assigned positions within each analytical rack generated by our proprietary LIMS. These QC materials provide a final verification of the entire analytical process. IN DATA REVIEW AND EVALUATION This is the final layer that is made up of sophisticated proprietary software and professional personnel reviewing the data. For more information on the BVM Quality program, refer to the guidance document BVM Quality Control: Definitions and Guidelines for the Interpretation of Quality Control 4 Bureau Veritas Minerals Schedule of Services & Fees 2017

5 WebAccess WebAccess is a secure web interface for our customers to obtain direct access to the Bureau Veritas Upstream Minerals laboratory database. WebAccess allows real-time access to any of your jobs logged into our LIMS. Track your samples from reception through the lab and see data results any time of the day or night. When critical conditions are detected, customers are notified immediately. Tests that indicate the need for a major inspection are double-checked prior to your notification. SAMPLE TRACKING SYSTEM BVM uses our secure LIMS (Laboratory Information Management System) to track the flow of every sample through each stage of sample handling and analysis. When received, each sample is bar coded and labeled. This unique barcode is used to build an audit trail that documents the complete history of work performed on each sample. It includes the recording of each person that interacted with a tracking feature sample and the task that they performed. This tracking feature provides the laboratory with a very high level of control but also provides our clients with an unprecedented level of traceability. CUSTOMERS HAVE ACCESS TO Sample submission forms, certificates and invoices Project documents such as the pricing quote and template submission form Analytical Methods documents available in most types of formats Quality Control documents reviewing analytical performance BOX TRACKING SYSTEM Each bar coded sample is allocated into a bar coded sample box, [(typically 36 samples per box), but there could be up to several hundred per box]. The barcodes allow BVM to track each box as it moves from one laboratory to another and allows our clients to monitor the progress of their samples from a remote sample preparation facility to the main laboratory. More importantly, this system speeds the flow of the samples through the laboratory to eliminate time consuming manual steps and reduce the risk of human error.

6 Innovations Spectrometry FOURIER TRANSFORM INFRA-RED (FTIR) SPECTROMETRY Bureau Veritas Minerals (BVM) houses 2 Fourier transform infra-red spectroscopy (FTIR) instruments. The FTIR technique measures light absorbed by a sample in the Infra-Red (IR) region of the light spectrum [spectral range of SWIR-LWIR-TIR (1,665-26,456 nm)]. To use the FTIR technique the spectrum from a number of samples that have already been analysed by classical methods (i.e, geochemistry, mineralogy) is collected. A mathematical correlation for each analyte is determined from the spectra, and then used to analyse unknown samples. Normal sample preparation schemes are used to produce a dried pulp. The FTIR spectra are collected without any additional preparation. There are no digests, fusions or other processes required. Bureau Veritas has successfully completed Bauxite and Iron Ore programs, however other ore types are being tested. Please consult with our laboratory to design the calibration set and analytes. HYLOGGER (VNIR AND SWIR) SPECTROMETRY The Hylogger system (Australia) can be used on core, rock chips, or pulps for the determination of an extensive list of minerals including Fe oxides, AlOH group minerals, sulphates, FeOH group, MgOH group, and carbonates. Application of VNIR and SWIR Analysis: Alteration vectoring Lithocap investigations Geometallurgy applications Benefits: Cost effective mineralogy Little sample preparation required (analysis can be conducted on core, chips or pulps) Non-desctructive Easy set-up on site application TERRASPEC HALO MINERAL SPECTRAL INTERPRETATION SERVICE In partnership with ASD Inc., BVM offers the TerraSpec Halo Mineral Spectra Interpretation Service. This service analyzes the BVM Hylogger or TerraSpec generated spectra using the TerraSpec Halo algorithm to predict up to seven minerals and nine mineral scalars* that may be present in a sample. Please contact a BVM representative for details. 6 Bureau Veritas Minerals Schedule of Services & Fees 2017

9 Sample Preparation, Storage & Disposal Sample Preparation Storage & Disposal Sample preparation lays the groundwork for all analysis which will be performed on your samples, and is key to the overall high quality of the analytical results we produce. A homogeneous split is taken to represent the original sample. The preparation process and this split are subject to QAQC control checks during the progression, as well as prior to sample analysis. If there is a non-conformance to the quality standard, the process is reviewed and corrected. This rigorous policy applies to any material that is reported or used in the analytical process. To ensure the equipment is producing a quality product, reduction of the wear surfaces of plates and bowls is constantly monitored and recorded. No equipment is allowed to be used beyond its lifespan. A sieve test is used to monitor the process on select and random samples at the primary crushing stage and at pulverization. These tests are recorded and produced for your review. Employees go through a comprehensive training program, thus ensuring that our staff understands the importance of its work and the adherence to a high quality standard.

21 Exploration Geochemistry Exploration Geochemistry Methods in this section are designed for non-mineralized to weakly mineralized material. They have been optimized to provide extremely low detection limits and maximum anomaly to background contrast. Modified aqua regia packages that target labile elements in soil, to more aggressive multi acid digestions that give near total results in all sample matrices are included. For projects with a gold focus, larger sample sizes are available to provide the most representative sample possible and mitigate nugget effects. This section also includes methods designed specifically for other media including biogeochemical exploration and natural water analysis. Bureau Veritas Minerals Schedule of Services & Fees

22 Aqua Regia Using a modified aqua regia digestion (1:1:1 HN :HCl:H 2 O) considered a partial digest, can provide valuable information regarding mobile and easily soluble species, such as sulfides. Economically priced ICP-ES (AQ300) or ICP-ES/MS (AQ200) analysis were designed to complement your exploration project. Sample splits of 0.5 g, 15 g or 30 g are leached in modified aqua regia.

Used sequentially, the leaches can determine whether elements in soils are present as salts, adsorbed to clay minerals, adsorbed/complexed with organics, or associated with amorphous Mn and Fe hydroxides. Used singularly, the stronger leaches are less selective.

27 Vegetation Analysis We offer two types of vegetation preparations depending on the elements of interest and application of the results. The first is an aqua regia digestion on the raw material. This method is best where volatile elements such as As, Se, and Hg are of interest. The second type of preparation involves the ashing of plant material followed by aqua regia digestion. Ashing is effectively a preconcentration step that allows for the detection of low level precious metals that would otherwise be below instrument detection.

29 Analysis of Natural Waters ICP-MS Surface and groundwater surveys are an effective means for exploration of remote and blind ore deposits. Method SO200 (analysis by ICP-MS) provides the low detection limits needed to define background and anomalous levels of cations in natural water. For this analysis all water samples must have less than 0.1% total dissolved solids (TDS). This method is not suitable for brines or processed solutions. Analysis of water geochemical parameters including ph, electrical conductivity, alkalinity, and anions provides the necessary parameters for complete characterization of water samples. Complete water characterization allows for the determination of not only the type of water (i.e., Ca-SO 4 or Na-CI), but how the type of water relates to ore deposit pathfinder elements. This package is not suitable for environmental surveys.

34 Nickel Laterite Analysis Exploration and evaluation of nickel laterite requires total determination and mass balance accounting of the major rock-forming elements and the commodity elements Ni, Cu and Co. BVM delivers these requirements, by combining a cost effective ICP-ES whole-rock determination and a total digestion multi-element assay, or analysis by XRF. Laterite Standard suite by XRF This package uses a predetermined amount of sample dried at 105 o C to remove moisture to ensure that the hygroscopic nature of the material does not add error to the analysis. A test portion of that dried material is then fused in a platinum gold crucible with a lithium tetraborate flux and cast into a disc. Fused discs are analyzed by XRF. Another test portion of dried sample is roasted at 1000 o C to determine the loss on ignition. Lithium Borate Fusion ICP-ES This package contains four separate analytical tests, 11 major oxides, 10 minor and trace elements, loss on ignition and SUM. SUM is the total of these constituents that gives a mass balance close to 100% when all the major constituents are accurately determined and accounted for. The redundancy of two separate Ni determinations (LF320 and MA370) provides an additional check on accuracy.

35 Laser Ablation Packages This package utilises high productivity robotic fusion technology with state of the art laser ablation and ICP-MS instruments to provide a fully extracted quantitative analysis for all elements. This method can be coupled with wavelength dispersive XRF to provide a complete quantitative total whole rock analysis. Where elements are available by both XRF and LA-ICP- MS, a matrix dependent determination will make for the most appropriate reporting instrument. Detection limits are comparable to traditional multi acid digestion methods. The technique offers safety and environmental advantages as there are no acids used in digestion, and it is fast and repeatable.
