Nortwest Arctic Borough, Alaska - Red Dog Mine
In 2012, Teck Alaska contracted AES to supply a team of geologist to execute the geotechnical engineering drill program, designed to elucidate the structure of the deposit at depth, and to provide the data to evaluate pit slope stability. The geotechnical team measured and collected structural and geotechnical data from oriented core on a production drill rig, while supervising the geotechnical drilling on-site and creating the geotechnical database.
Kodiak Island, Alaska -Shakmanof QuarryAES has been providing geologic consulting to Koniag Native Corporation for its proposed Shakmanof quarry since 2009. AES completed a geologic and structural interpretation of aerial photography and Lidar data, followed by mapping rock outcrops within the project area. We completed a diamond-core drilling program of six holes to test rock quality and confirm the structural regime. The quarry would make use of granitic rock for construction material.
Naknek, Alaska – Naknek Electric Association Road/Pad ConstructionIn 2009, AES and Recon, LLC designed and managed the construction of a 2 mile long road and drill pad for the Naknek Electric Association. AES completed aerial photo interpretations to delineate wetlands, gravel sources for road and pad material, and potential road alignment routes. Test pits were dug to characterize the surficial geology and to test construction material borrow sources. In addition, AES completed a Stormwater Pollution Prevention Plan (SWPPP) and oversaw the plan’s implementation during construction.
Wrangell Island, Alaska – Tyee Hydroelectric ProjectRobert Retherford was the lead geologist for an investigation of potential lake tap sites on Wrangell Island in Southeast Alaska. The investigation consisted of mapping the surficial geology and geologic hazards around potential infrastructure as well as completing rock strength and competency tests, and drilling.
Big Lake, Alaska- Rietz Gravel, Aggregate Resource EvaluationIn 2005, AES conducted a surface investigation and completed test pits to evaluate a potential medium scale aggregate mining operation in the Big Lake area of Alaska. Prior to fieldwork, aerial photography was interpreted and glacial and periglacial features were identified to characterize the project area and assist with locating viable test pit locations.
“One of the several benefits of having geological contractors as our drilling contractor on this job is for the first time in my career, I feel like I am on the same page with our drillers.”Sam Dashevsky, Northern Associates
