Tierra Group completed a technical review of the heap leach pad for the Amulsar Mine property owned by Lydian Armenia located near the town of Jermuk to the southeast of Armenia. The heap leach pad consists of four phases with a rich pool and three contingency pools. Tierra Group was hired to conduct a third-party review and audit the design of the heap leach pad. After the review, Tierra Group provided a series of recommendations to optimize the design of the pad. Tierra Group continues to review new interface shear strength tests and will also be in charge of reviewing the new stability analysis that will be updated using the new geotechnical parameters. In addition, Tierra Group will continue reviewing the changes in the heap leach pad design.
