Developer Integra Resources has appointed Mine Development Associates (MDA) as the lead consultant for a pre-feasibility study (PFS) of the DeLamar gold-silver project in Idaho. The study is expected to take 10 months to complete and results are expected in the fourth quarter of 2021.

MDA will be responsible for the resources and reserves, geology, open pit design, infrastructure design, mine scheduling, cost estimates and execution planning. M3 Engineering and Technology will provide a design for the process facilities, access and power infrastructure. Welsh Hagen has been selected for design of the tailings facility and heap leach pad.

The U.S. division of SRK Consulting will start geochemical baseline studies in the fourth quarter, and aim to select samples and complete tests in the first quarter of next year.

“The upcoming DeLamar project pre-feasibility study will be based on similar parameters that led to the robust 2019 preliminary economic study, demonstrating a baseline of gold and silver production to come from the heap-leaching of oxide and transitional gold and silver mineralization from the Florida Mountain and DeLamar deposits,” George Salamis, Integra’s president and CEO said in a release.

Salamis also added that while last year’s preliminary economic assessment (PEA) for the project assumed a 2,000 t/d milling scenario for the sulphide mineralization, in addition to heap leaching, the upcoming PFS will focus on a larger milling option.
