5 1 INTRODUCTION Assured Monitoring Group (AMG) was commissioned by CBH Resources to monitor emissions from their vent shaft sample point and mill baghouse at the Rasp Mine facility, Broken Hill. Sampling was conducted by AMG on 2 nd September AMG was responsible for the collection and analysis of samples, unless otherwise indicated. The samples were recovered and stored in the appropriate manner until their return to the laboratory where the samples were prepared and analysed according to the appropriate methodology. This test program was conducted to: Monitor emissions from the Vent Shaft sample point Monitor emissions from the Mill bag house Project ID: R_0 1

6 2 METHODOLGY & EQUIPMENT 2.1 Sampling methodology Unless otherwise stated, the following test methods meet the requirements of NSW EPA. All sampling and analysis was conducted by AMG unless otherwise stated. The results presented in this report are related to one or more reference calibrations held by AMG. All sampling and analysis was carried in accordance to the listed requirements in Table 4. Any deviations to these methods have been documented where required.

The sampling duration on the vent shaft is timed to coincide with a blast within the mine and is run for a period to time to cover the emission of any potential blast fume. Only NOx calibration gas taken to site to perform on-site calibration checks. For all other gases, analyser calibration checks were performed in laboratory conditions before and after sampling, not on-site. Project ID: R_0 2

10 3 QUALITY ASSURANCE & QUALITY CONTROL (QA/QC) AMG operates within a quality system based upon the requirements of ISO Our quality system defines specific procedures and methodologies to ensure any project undertaken by AMG is conducted with the highest level of quality given the specific confines of each project The overall objective of our QA/QC procedures is to representatively sample and accurately analyse components in the gas streams and therefore report valid measurements of emission concentrations. To ensure representativeness of field work, our quality procedures target: 1. Correct sampling locations 2. Sample time 3. Frequency of samples and 4. Method selection & adherence To ensure representativeness of lab work, our quality procedures target: 1. Sample preservation 2. Chain of custody (COC) 3. Sample preparation and 4. Analytical techniques AMG maintains strict quality assurance throughout all its sampling programs, covering on-site field work and the analytical phase of our projects. Our QA program covers the calibration of all sampling and analytical apparatus where applicable and the use of spikes, replicate sample and reference standards. The test methodologies used for this project are outlined in section 2 of this document. Field test data has been recorded and calculated using direct entry into Microsoft Excel spreadsheets following the procedures of the appropriate test methods. Determination of emission concentrations has been performed using the same Microsoft Excel spreadsheets which are partially supplied as an attachment to this report. More detailed information can be supplied upon request. QA/QC checks for this project will use validation techniques and criteria appropriate to the type of data and the purpose of the measurement to approve the test report. Records of all data will be maintained. Complete chain of custody (COC) procedures has been followed to document the entire custodial history of each sample. The COC forms also served as a laboratory sheet detailing sample ID and analysis requirements. Project ID: R_0 6 File name: CBH Resources Sep 2015 R_0
