Mr. Jack Phipps, JVP Construction, Incorporated, 692 Eton Boulevard, Fairbanks, Alaska 99709. The applicant’s stated purpose is gold recovery by the use of placer mining. All access roads are pre-existing and located within uplands. The applicant’s proposed work is to mine gold from the 6.0-acre project site by using a placer mining system consisting of an eight feet long trammel with a sluice box and a three-foot-wide oversized conveyer. The project would involve the placement of approximately 48,000 cubic yards of gravel fill, consisting of approximately 40,000 cubic yards of rock, cobble, and gravel fines, and approximately 8,000 cubic yards of organic overburden annually, via mechanized land clearing in 6.0 acres of wetlands. Additional work includes an approximately 880 feet long by 15 feet wide by 6 feet deep temporary stream diversion of Ketchum Creek which was constructed in 2019 to present. The physical wash plant would remain in the same location and project plans from 2019 and would not change for the plant. Pay gravels would be delivered to the location from the new mining cuts to be processed. The project has been designed to occur in phases. All work from the 2019-2021 mining seasons have been reclaimed by utilizing a rolling footprint, and reclamation work has been accepted. During the 2022 mining season the remaining cuts of Ketchum Creek near the confluence of Upper Ketchum and Mary Louise Creeks will be completed. Upon completion of work the stream diversion in Ketchum Creek will be reclaimed prior to starting work in Mary Louise or Upper Ketchum Creeks. Next, from 2022 to 2023, the operation will proceed with work within Mary Louise Creek. An approximately 2,000 feet long by 15 feet, wide by 6 feet deep temporary stream diversion would be constructed. Mining would consist of work within the streambed and also within previously mined ground along the Mary Louise Creek mining areas. Once work at Mary Louise Creek is finished, and the stream bypass and mining cuts reclaimed, work would advance to Upper Ketchum Creek. Mining of the Upper Ketchum Creek area is expected to occur from 2023 to 2025. Test trenches, sized approximately 500 feet long by 5 feet wide by 15 feet deep will be excavated to survey for profitable gold resources. Ground at the Upper Ketchum Creek location has also been previously mined, and additional work will include an approximately 660 feet long by 15 feet, wide by 5 feet deep temporary stream diversion. The planned cuts and would be reclaimed after the completion of the mining process. All work would be performed in accordance with the enclosed plan (sheets 1-20), dated February 8, 2022. The project site is located within Sections 1, 7, & 12, T. 7 N., R. 14 7 15 E., Fairbanks Meridian; USGS Quad Map Circle B-2; Latitude 65.457497º N., Longitude 144.756348º W.; near Central, Alaska.
