ICMC RECERTIFICATION SUMMARY AUDIT REPORT <br /> Cyanide tanks and pipelines are constructed of materials compatible with cyanide and high pH conditions. <br /> Concerning tanks and pipelines of ADR1 and VLF1,the 2014 recertification audit report states that"CC&V <br /> uses carbon steel, stainless steel, HDPE,and polyvinyl chloride("PVC")piping materials and piping system <br /> components.All cyanide process tanks are constructed of carbon steel." Regarding tanks and pipelines for <br /> the new cyanide facilities(i.e.,the HGM,ADR2, PSES Plant,and VLF2),all cyanide pipelines were <br /> constructed of carbon steel and HDPE.Cyanide tanks were constructed of carbon steel.The auditors <br /> reviewed design, as built and QA/QC documentation to verify compliance. <br /> Standard of Practice 4.8: Implement quality control/quality assurance procedures to confirm <br /> that cyanide facilities are constructed according to accepted <br /> engineering standards and specifications. <br /> ® in full compliance with <br /> CC&V is: ❑in substantial compliance with Standard of Practice 4.8 <br /> ❑not in compliance with <br /> Summarize the basis for this finding: <br /> The operation is in FULL COMPLIANCE with Standard of Practice 4.8; implement quality control/quality <br /> assurance procedures to confirm that cyanide facilities are constructed according to accepted engineering <br /> standards and specifications. <br /> The existence and contents of the construction QA/QC programs implemented for the cyanide facilities, <br /> constructed and in operation at the time of the 2007 initial certification audit and the 2010 and 2014 <br /> recertification audits,were evaluated and found compliant during those audits. <br /> QA/QC programs have also been implemented during construction of the cyanide facilities that are new <br /> since the previous recertification audit.The auditors reviewed record of construction reports,which include <br /> as built drawings, QA/QC completion reports, QA/QC testing results,and Commission Packages. <br /> CC&V has implemented QA/QC programs that address the suitability of materials, adequacy of soil <br /> compaction for earthworks,and installation of geomembrane liners.QA/QC documentation describe the <br /> parties involved, QA/QC activities and testing,design modifications, and as built drawings. <br /> CC&V has retained design, as-built,and construction QA/QC records for all cyanide facilities on site <br /> (including new and existing cyanide facilities).The auditors spot checked the list of evidence from the 2014, <br /> 2010 and 2007 audits against the hard and electronic copies on site to verify documents were retained. <br /> Appropriately qualified personnel reviewed and approved the construction projects completed during the <br /> recertification period including professional engineers and CC&V project Superintendent and QA/QC.QA/QC <br /> reports,signed and stamped by professional engineers,state that the projects were constructed in general <br /> accordance with the approved design and specifications,as such meets the design intent. <br /> Standard of Practice 4.9: Implement monitoring programs to evaluate the effects of cyanide use <br /> on wildlife,surface,and groundwater quality. <br /> ®in full compliance with <br /> CC&V is: ❑ in substantial compliance with Standard of Practice 4.9 <br /> ❑not in compliance with <br /> Summarize the basis for this finding: <br /> The operation is in FULL COMPLIANCE with Standard of Practice 4.9; implement monitoring programs to <br /> evaluate the effects of cyanide use on wildlife, surface, and groundwater quality. <br /> CC&V has developed written procedures for water sampling and wildlife monitoring.The document entitled <br /> "Environmental Sampling Protocol Guide"and the Sample Prep&Shipping Summary specify the details of <br /> CC&V Mine - July 28,2017 <br /> Name of Facility Signature of Lead Auditor Date <br /> July 2017 Gofer <br /> Report No.1663584-003-R-RevO 1s isociates <br />
