PERMIT#:M-1980-244 <br /> INSPECTOR'S INITIALS:ERR <br /> INSPECTION DATE:January 13,2021 <br /> PROBLEMS/POSSIBLE VIOLATIONS <br /> None observed during the inspection. <br /> OBSERVATIONS <br /> This was an aerial photo inspection of the Cresson Project directed by Elliott Russell of the Colorado Division <br /> of Reclamation, Mining and Safety (Division)based on aerial photographs taken by Brock Bowles of the <br /> Division on January 13, 2021. The Operator did not accompany the Division on this aerial inspection. The site <br /> is a 112d-3 gold mine located between Cripple Creek and Victor in Teller County. The purpose of these aerial <br /> inspections is to provide the Division a broad perspective that cannot be obtained from the ground and to <br /> document changes in areas of the mine over time. <br /> This inspection included the following facilities and areas: <br /> • Arequa Gulch Valley Leach Facility; <br /> • Squaw Gulch Valley Leach Facility; <br /> • High Grade Mill and ADR Facilities; <br /> • East Cresson Overburden Storage Area; and <br /> • Schist Island, Globe Hill, WHEX, Main Cresson, and South Cresson Pits. <br /> Arequa Gulch Valley Leach Facilit(AGVLF, a.k.a. VLF 1) <br /> No ponded process solution was observed in the active leach areas of VLF 1 (see Photo 1 and Photo 2). No <br /> observable issues are noted for VLF 1. <br /> Squaw Gulch Valley Leach Facility(SGVLF, a.k.a. VLF 2) <br /> No ponded process solution was observed in the active leach areas of VLF 2 (see Photo 3). Active ore stacking <br /> occurring in the northeast portion of VLF 2 appeared to be in compliance with TR-103 (see Photo 4). No <br /> observable issues are noted for VLF 2. <br /> High Grade Mill and ADR Facilities <br /> Aerial images of the High Grade Mill (HGM), Adsorption, Desorption, and Recovery Facilities (ADR), and the <br /> Process Solution Enhancement System Facility (PSES) are used to perform a broad visual inspection for leaks, <br /> spills, secondary containment problems, and other potential issues that cannot easily be obtained from the <br /> ground. The HGM is located between VLF 1 and VLF 2. No observable issues are noted for the HGM (see <br /> Photo 4 and Photo 5). ADR 1 (see Photo 6) and the PSES (see Photo 7) are both located on the south side of <br /> VLF 1 while ADR 2 (see Photo 8) is located on the west side of VLF 2. No observable issues are noted for <br /> either ADR facility or the PSES. <br /> East Cresson Overburden Storage Area(ECOSA) <br /> Overburden placement was occurring on the northwestern portion of the ECOSA (see Photo 9). The Operator <br /> recently completed approximately 35 acres of concurrent reclamation on the southeastern portion of the ECOSA <br /> (see Photo 10). It appears a portion of the reclamation project did not fully key into the topography of adjacent <br /> undisturbed areas, leaving an exposed highwall remnant of the backfilled Altman Pit(see Photo 11). The <br /> Division will further investigate this area during a future normal monitoring inspection. <br /> Mining Pits <br /> Aerial images of the Schist Island(see Photo 12), Globe Hill (see Photo 13), WHEX (see Photo 14), Main <br /> Cresson (see Photo 15), and South Cresson Pits (see Photo 16) are presented for comparison with previous <br /> aerial inspection reports. Based on aerial photos taken at the time of the inspection, active mining was occurring <br /> Page 2 of 11 <br />
