The first phase of the project was successfully delivered on a highly accelerated schedule, despite unusually wet weather and significant site challenges. For example, the site elevation had to be raised by eight feet before construction of the leach plant could begin, which meant substantial earthwork had to be performed under consistently rainy conditions. A temporary on-site power plant was also constructed to support ongoing operations and keep the project on schedule.
Despite the challenges, the leaching plant was designed and built in five and one-half months—less than half the time normally required. The caverns were solution-mined, tested and delivered about six months later. Our extensive experience in the development of solution-mined storage facilities was a key factor in the successful delivery of the project.
