Round Mountain Phase W

Round Mountain Phase W

Founded in 1993, Kinross Gold is a gold mining company with a diverse portfolio of mines and projects in the United States, Brazil, Chile, Ghana, Mauritania, and Russia. Headquartered in Toronto, Canada, Kinross employs approximately 9,000 people worldwide. The Round Mountain site is an open-pit mine located in Nevada, one of the best mining districts in the world. Round Mountain uses conventional open-pit mining methods, and processes ore by mill and heap leach.

Kinross Gold proposed a significant mine pit expansion to the west highwall of the Round Mountain mine. This 1,200-foot pushback necessitated the relocation of the existing infrastructure including a secondary crusher, wash bay, truck shop, warehouse, mine operations building, and fuel island. In addition, Kinross needed a new heap leach pad to accommodate ore that was generated from the mine pit expansion. Kinross also proposed to construct a new solution processing facility—a Vertical Carbon-in-Column plant (VCIC)—to support this new heap leach pad.

Kinross selected Morrison-Maierle in September 2017 to perform detailed engineering for a variety of infrastructure and processing needs. These included the truck shop, warehouse, lube room, wash bays, mine operations building, fuel islands, wet and dry utilities, and VCIC plant. The expansion also included site grading and drainage to support the new facilities. Certain elements of the design were accelerated to support the procurement of long-lead items or long-duration construction. These included pre-engineered metal buildings, process pumps, variable frequency drives, and an electrical house. Morrison-Maierle focused early design efforts on these elements to support the supply chain, ensuring the timely arrival of construction items.

The design team produced an early set of Issue-for-Bid documents that enabled the general contractor to go under contract concurrent with the release of Issue-for-Construction documents. Over 4,000 pages of technical specifications, 602 drawings, 30,769 person-hours and 62 personnel were involved in this project. Detailed design was completed in May 2018.

From cost-saving building features to measures to ensure energy efficiency and sustainability, this fast-tracked project delivered a solution that used all of Morrison-Maierle’s engineering disciplines.
