Lydian International Ltd.’s wholly owned Armenian operating subsidiary has signed key equipment supply contracts for its 100% owned Amulsar gold project in Armenia. These contracts, signed ahead of the 2017 construction season, will provide all significant components of the mining fleet, materials handling system, gold-recovery plant, electrical systems, and worker accommodations.
Zeppelin International AG (Zeppelin) has been contracted to supply Cat mobile mining equipment, including haul trucks, shovels, tractors, loaders, dozers and other units of mining support equipment. Zeppelin has committed to initial deliveries starting in the third quarter of 2017.
Mine production is estimated at approximately 25 million total metric tons (mt) of material during the first year of operation. Later equipment additions will increase average mining capacity to approximately 35 million total mt of material per year.
The materials handling system for Amulsar will be supplied by Sandvik. The crushing and screening plant will be supplied by Sandvik SRP AB Sweden, and the overland conveyor, storage reclaim and truck loadout feeding system by Sandvik Mining and Construction Oy Finland. The crushing and screening plant will include a vibrating feeder, a primary jaw crusher and three secondary cone crushers, with a nominal design capacity of 10.5 million mt/y at a crush size of 80% passing 18 mm. The Sandvik overland conveyor will extend approximately 5.6 kilometers with an elevation drop of 700 meters from the crushing and screening plant to the truck loadout facility. The conveyor is designed to transport crushed ore at a nominal rate of 13.1 million mt/y. Initial deliveries of components for the overland conveyor are expected to begin during the second quarter of 2017, with other conveyor, crushing and screening deliveries to continue through the third quarter.
AZMET Technology & Projects will design and supply the adsorption, desorption and recovery plant (ADR Plant). The ADR Plant is being designed to treat up to 1,100 m3/h of pregnant solution through a five-stage adsorption circuit. Four mt of loaded carbon will be eluted twice per day in a pressurized elution circuit, which will be followed by zinc precipitation. The gold and silver bearing precipitate will then be smelted in a gas fired furnace to produce doré bars.
ABB AB, Substations and ABB Switzerland Ltd. (ABB) are under contract for design and supply of equipment and materials for complete plant electrification. This will include the main substation and distribution grid, integrated automation and process control by optimized solutions, motors and drive systems, as well as premanufactured electrical rooms to house the whole plant electrical infrastructure.
The company also entered into contracts with Renco SpA and Renco Armestate (Renco) for design, supply, construction and assembly of a 680-bed residence camp immediately adjacent to Amulsar. Renco mobilized during the first quarter of 2017, with initial occupation of the camp planned for the second quarter. Renovation of a local-area hotel has also been completed and will be used for accommodations until the camp is completed.
