GURAY SILVER McvES <br /> a. The 94% compaction requirement for the TSF will be verified using a nuclear density <br /> gauge.Specifications attached. <br /> Mill Facility-Construction/Design Specifications <br /> 3. General Design Summary <br /> a. Provide a list of all equipment and tanks present throughout the mill circuit. Specify <br /> the contents, location and sizes. <br /> b. If available, provide a 3D rendering of the mill and the various areas throughout <br /> the circuit. <br /> Response: <br /> a. A list of all equipment and tanks present throughout the mill circuit can be found in <br /> Table 7. <br /> b. A 3D rendering of the mill is not available. However, the mine would be happy to tour <br /> the mill facility with the Division so that they can see the space in 3 dimensions. <br /> 4. Details regarding how the concrete foundation and containment structures were designed and <br /> built,including any coatings applied to the floor and orwalls.If QA/QC documentation is available <br /> for the construction this should also be included. <br /> a. Include a narrative summary to address the item above. Detailed drawings have been <br /> provided. <br /> b. Additional information regarding secondary containments features are address(ed) in a <br /> later section <br /> Response: <br /> a. The mill was constructed by a previous operator and no as-built drawings or QA/QC <br /> documentation are in OSMI's possession. The 2015 Revenue Mine: Mill Certification <br /> describes previously existing mill construction and environmental protections. The <br /> previous mill certification is attached for the Division's reference. <br /> b. Noted. <br /> 5. Include drawings and narrative of all piping and delivery systems that contain designated <br /> chemicals <br /> a. Verify that the entire length of delivery lines exist within a form of secondary <br /> containment (also see Secondary/Tertiary Containment Structures section) <br /> Response:Piping and delivery system drawings are attached—see P&ID drawings. <br /> a. The entire length of delivery lines are within secondary containment. The reagent <br /> chemicals start in the reagent room which is approved as an environmental protection <br /> facility. From there the lines enter the compressor room which has an 8-inch vertical curb <br /> and then into the mill. In the compressor room the lines will be double walled. <br /> 6. On page 6 it is noted that drawing 300-PI-004 has the Zn rougher conditioning tank mislabeled. <br /> a. Drawing 300-PI-004 was not referenced in Appendix 1 nor has it been provided to <br /> the Division. Provide the Division with the reference drawing. <br /> 2 1 P a g e <br />
