Alaska Hydro Announces Receipt of Golder Dam Design Report for More Creek
Vancouver, British Columbia--(Newsfile Corp. - September 13, 2017) - Alaska Hydro Corporation (TSXV: AKH) President, Cliff Grandison, announced the receipt of Golder and Associates' report on the dam design and cost estimates for the Company's More Creek hydroelectric project. The report includes the assessment of four different dam types, all of which were considered to be viable choices. The dam types studied were concrete arch, roller compacted concrete, rock fill and earth fill dams. The pre-feasibility study was based on a roller compacted concrete dam. The Golder study identified the arch concrete dam as the least expensive of all types and at a reduced cost compared to the roller compacted concrete dam originally selected with the potential for additional cost savings through optimization of the coffer dam and bypass tunnel. The arch concrete dam design will have a significant impact on other components which will further reduce costs and be the subject of a revised prefeasibility study.
The location of the dam site was also visited. The report identified the best site in the More Creek Canyon would be approximately 400 metres downstream of the initially proposed dam site. This location will result in a substantial cost saving in the construction of the power water tunnel.
The proposed arch concrete dam will require a review of other dam related variables such as access, elevation, construction methods and schedule.
The revised prefeasibility is expected to be available within a couple of weeks and is expected to improve upon the initial feasibility.
Engineering and technical studies will continue with the immediate objective of collecting accurate site specific data such as topography and geology.
