Minto Mine

Project Overview

The Minto Mine is a high grade copper-gold mine located 240 km north of Whitehorse, Canada, and is owned 100% by Minto Explorations Ltd., a wholly-owned subsidiary of Capstone Mining Corp. The Minto Mine is an open pit mining operation with conventional crushing, grinding, and floatation to produce copper concentrates with significant gold and silver credits.

Project Scope

JDS was retained by Capstone to provide Engineering and Construction Management (EPCM) services in late 2005 to design and build a 1,400 ton/day process plant, develop the mine and dry stack tailings facility, design and build a barge to traverse the Yukon river for access to site, construct an airstrip, 3 MW power plant, 130 person camp and supporting infrastructure. From the acquisition in mid-2005 to commercial production in June 2007, JDS led the feasibility study, managed the detailed engineering which was performed by Hatch and EBA, performed the procurement, managed the construction completed by Clark Builders and Pelly Construction and led commissioning completed by Clark Builders and Capstone personnel, delivering the project on-schedule and on-budget. JDS also provided significant input on permitting and geo-technical information.

Project Value: $101M

JDS was subsequently retained to complete the EPCM services on the first expansion to 2,600 ton per day as well as the erection and commissioning of a water filtration unit for environmentally safe discharge; which were executed on-schedule and on-budget.

Project Value: $36M

JDS also completed the EPCM services for the second expansion to 3,500 ton / day which again was completed on-schedule and on-budget.

Project Value: $10M
