Sabina Gold & Silver Updates on Detail Engineering and Constructability Review Contracts for Proposed Goose Mine at Back River Gold Project in Nunavut, Canada
Sabina Gold & Silver Corp. report that the detail engineering contract has been awarded and work has commenced on the Goose Mine at its 100%-owned Back River Gold Project (“Back River” or the “Project”) in Nunavut, Canada. After comprehensive evaluation of various construction delivery methods for the Process Plant at Goose, Sabina believes that a modified Engineering, Procurement, Construction Management (“EPCM”) method offers the greatest efficiency, flexibility and risk mitigation for development of the Goose Project. This delivery model includes completion of detail engineering in a reimbursable cost model for engineering and procurement directly sourcing major process equipment, and pursuit of a fixed price construction bid. Detail engineering will provide definitive material requirements per AACE class II standards (up to 70% project definition) and will result in development of procurement packages and delivery of issued for construction drawings. This approach de-risks the engineering aspect, better defines the execution plan and provides greater certainty of procurement and construction costs. With these details in hand, Sabina will solicit fixed price construction bids for the plant, including performance guarantees. Sabina has engaged Sacré-Davey Engineering Inc. (“SD”) to complete the detail engineering scope for the process plant and experienced Arctic builders, CGT Industrial (“CGT”) to review and evaluate the detailed design's constructability and operability. The CGT team is also assisting in developing a construction execution plan. SD has extensive experience ranging from feasibility studies and concepts to detailed design, system integration, and construction. They have executed projects across many industries, including mining, oil & gas, and forestry, among others. CGT is a northern Arctic constructor with proven experience in the mining industry with a successful track record of involvement in projects that includes Pretivm’s Brucejack gold mine, Dominion Diamond’s Ekati and Diavik Diamond mines and Yukon Zinc’s Wolverine mine. Both detailed engineering and the constructability and operations review have begun and are expected to be completed during first quarter of 2021. Sabina had selected FLSmidth (“FLS”) as the equipment manufacturer and FLS is actively working on their line-up of equipment and a definitive pricing model with a performance guarantee for the plant. FLS will also be engaged in commissioning support and critical spares management. This continued engagement with FLS will provide Sabina with more certainty for the phases of the Project throughout detailed engineering, commissioning, optimization, and training. Sabina is also reaching out to power plant technology providers to support the design and development of construction drawings for a ~15MW power plant. Sabina expects this contract will be awarded before the end of the year. Sabina has engaged DT Engineering to design the Port Facility fuel farm and fuel distribution process. The objective is to receive, store and dispense 40 Million liters at the Port Facility area and at the Goose site. Sabina consultants are also working on the design of various water diversion structures designed to mitigate seasonal flow, site wide road networks, waste dump designs and site wide water balance calculations. In 2019 Sabina obtained a third-party logistics review for Project construction. As part of the process, Sabina engaged various vessel operators to do a logistics review while finalizing plans for the material consolidation points for the Project, the Port Facility receiving schedule and offloading requirements. The inaugural winter ice road in 2018/19 provided the experience required to develop a robust logistics and procurement execution plan to support the Project’s material requirements. The opportunity enabled Sabina to conduct winter ice road time studies and road management plans. All these initiatives have been carried forward and will be incorporated into the updated Project execution plan. Sabina released a Feasibility Study on its 100% owned Back River Gold Project which presents a project that has been designed on a fit-for purpose basis, with the potential to produce ~200,000 ounces a year for ~11 years with a rapid payback of 2.9 years (see “Technical Report for the Initial Project Feasibility Study on the Back River Gold Property, Nunavut, Canada” dated October 28, 2015). The Project received its final Project Certificate on December 19, 2017. The Project received its Type A Water License on November 14, 2018 and its listing to enable deposition of tailings on Schedule 2 of the Metals and Diamond Mining Effluent Regulations on June 25, 2020. The Company is now in receipt of all major authorizations for construction and operations. In addition to Back River, Sabina also owns a significant silver royalty on Glencore’s Hackett River Project. The silver royalty on Hackett River’s silver production is comprised of 22.5% of the first 190 million ounces produced and 12.5% of all silver produced thereafter.
