Within Section 1.1,the 4th bullet point states the expansion includes a sixth PSSA to the <br /> VLF1 facility.Although this is Phase 6, it is the fifth PSSA of the facility. Please update the <br /> • text accordingly. <br /> Section 1.1 has been updated to indicate that the expansion includes a fifth PSSA to the VLF1 facility. <br /> A revised version of Exhibit D is included as (Attachment 2). <br /> 7. Exhibit D was not revised during the July 8, 2024 Response to Filing Deficiencies <br /> submittal, it pre-dates the details of the employee parking area along County Road 821. <br /> Please revise Section 2.1 to describe this expansion area of the affected lands. <br /> Section 2.1 has been revised to state that the total increase in acreage in Amendment 14 is 14.83 acres <br /> to include the access road that was constructed in Grassy Valley to support monitoring well installation <br /> (0.63 acres) and the employee parking area along County Road 821 (14.20 acres). The total affected <br /> lands for Amendment 14 constitute 6,017.53 acres. <br /> 8. Within Section 3, Paragraph 4, it is stated that higher-grade ore will be placed in one of <br /> four storage areas in the vicinity of the Main Cresson Mine area as shown on Drawing C-4. <br /> Drawing C-4 does not identify these four storage areas. <br /> This sentence was revised to state that higher-grade ore is temporarily stored near the crusher. <br /> 9. Within Section 3, Paragraph 4, it is stated that higher grade ore ultimately will be placed in <br /> the High-Grade Mill (HGM)feed area or crusher feed area to be processed through the <br /> HGM.Additionally, it is presented that the VLF2 expansion and the operation of the HGM is <br /> an "either-or" scenario. It is understood that the HGM is not currently in an Operational <br /> status as it has been shut down since the beginning of 2022. Please provide more <br /> information regarding the status of the HGM. Also, based on the evaluation of the mill, <br /> please provide more information regarding what measures are required to bring the mill <br /> 4111 into an operational status.The Division understands that reserving the option of use of the <br /> HGM allows for operational flexibility, however a separate revision may be required to <br /> address the recommissioning of the mill system. Lastly, in the event the AM14 VLF2 <br /> expansion does not occur and the HGM is recommissioned,the Operator will need to <br /> address Division's March 17, 2023 Outstanding Compliance Problem letter regarding <br /> modifications to the HGM liner. <br /> The HG Mill remains inactive. The following sentence has been added to Section 3, Paragraph 4 in the <br /> revised Exhibit D Mine Plan(Attachment 2): "Prior to construction of the planned VLF Expansion, CC&V <br /> intends to maintain operational flexibility and may utilize the existing HGM facilities to process HG ore. <br /> Prior to resuming HGM operation, CC&V will work with DRMS to ensure safe, compliant and effective <br /> startup of the facility" <br /> 10. Section 5.2 briefly mentions the demolition of the mill and infrastructure to allow for the <br /> expansion of the VLF's. Please provide more details regarding the demolition and removal <br /> of the mill, subgrade, liner system,wells etc,to allow for the construction of the VLF2 <br /> expansion. <br /> Details regarding the demolition and removal of the mill subgrade were provided in Appendix 1 Valley <br /> Leach Facility 1 Stage 6 and Valley Leach Facility 2 Stage 4 Expansions Detailed Design for Permitting, <br /> Section 4.3.1. This paragraph has been copied below for ease of reference: —The proposed footprint <br /> of the VLF2 Phase 4 Stage A Expansion is located under the existing Mill Platform, which is a lined <br /> area housing several buildings and miscellaneous infrastructure. Prior to construction, the Mill Building, <br /> along with any retaining walls and infrastructure will be removed. Any void and existing pipes in the <br /> area will be removed or grouted. The current grading plan places a minimum depth of structural fill over <br /> this area, so that the existing geomembrane will remain intact and buried under the proposed primary <br /> • liner. This expansion will be graded to drain towards the southwest, towards the existing VLF2 Phase <br /> 1/2 PSSA. Earthworks will be relatively minimal, as the proposed pad is generally located on compacted <br /> SSR Mining Inc. PAGE 3/19 <br />
