Metallurgical Testwork Initiated At The Eldorado Project

VANCOUVER – Provenance Gold Corp. announced that a multi-phase metallurgical testing program has been initiated for its Eldorado Gold project in eastern Oregon, which will include both bottle roll and column tests. The objective of the first phase of the program is to evaluate the Project’s amenability to heap leach extraction, including potential metal recoveries, leach kinetics, and reagent consumption across the property. The second phase of testwork will focus on assessing conventional extraction methods, including carbon-in-leach (CIL) and gravity-flotation processes.
Phase 1 Metallurgical Testwork: 1) 5 column tests covering composite, representative samples from the Tyee and the Herman Areas including the newly discovered mineralization between zones 1 to 4 in the Tyee Area as well as the mineralization extension in the Herman Area. 2) 20 simple bottle roll tests on the composites assembled from RC drilling to determine cyanide solubility of gold mineralization from a variety of geologic domains throughout the Project area.
This metallurgical testwork will be used to verify results from historical bottle roll tests and Provenance’s previous 2024 gravity and flotation tests completed by Dawson Metallurgical Testing Laboratories. Previous results returned an overall average of 88.1% (77.9-97.1%) gold recovery of unoxidized sulfide samples, recovered by gravity concentration followed by bulk sulfide flotation of the gravity tailings, indicating that a high proportion of gold is liberated using standard methods.
