7. Exhibits C4, C5 and C6 do not have a map legend. Please revise the maps to <br /> include a legend. <br /> Exhibits C4, C5, and C6 have been updated to include a legend. <br /> 6.4.4 EXHIBIT D - Mining Plan <br /> 8. Figure 13, Exhibit D2 has no map legend. Please revise the exhibit to include a <br /> legend. <br /> Exhibit D2 has been updated to include a legend. <br /> 9. What is the nature of the stratum immediately beneath the material to be <br /> mined in sedimentary deposits? This information is also not depicted on Figure <br /> 10-Exhibit D1 Mining Plan. Required under Rule 6.4.4(f)(ii). <br /> Figure 12, Exhibit D1 depicts the data obtained from the boring logs and Note 4 on <br /> Exhibits C4 and C5 provides a cross reference to the boring logs data, included in <br /> Detail 1/11 . The boring logs are included in the Attachment and show the <br /> distribution of this stratum across the property. The narrative in Section 5.2 has <br /> been revised to reflect the available information and general text from the United <br /> States Geological Survey (USGS) as follows, "The stratum underlying the material <br /> to be mined is bedrock consisting of claystone and siltstone facies of the Wasatch <br /> Formation (Footnote). <br /> Footnote text: United States Geological Survey. Geology map of the Silt <br /> quadrangle, Garfield County, Colorado. Miscellaneous Field Studies Map MF-2331 . <br /> Reston, Va: U.S. Department of the Interior. 2001." <br /> 10.The dates for the timeline in section 5.3 in Exhibit D need to be updated. <br /> The construction schedule in Section 5.3 has been updated to reflect the following <br /> narrative, "At this time, the proposed mine would operate daily, with excavation <br /> and processing occurring 8 months of the year (roughly April - November). Total <br /> recoverable volume is estimated at approximately 292,810 CY [cubic yards] of <br /> aggregate, which is expected to support operations for between three and five <br /> years." <br /> In addition, Exhibit E2 was revised to reflect the following schedule (the narrative <br /> was also added to Section 5.3): <br /> - March 2023 - start of site prep (LDA staking, overburden removal, and berm <br /> construction) <br /> - April 2023 - start of mining operations and concurrent reclamation as <br /> mining progresses <br /> - December 2026 to 2028 - end of mining operations and reclamation (life of <br /> mine estimated at 3-5 years) <br />
