Provenance Gold (CSE:PAU) has begun a multi-phase metallurgical testwork program at the Eldoradon Project in the US, which will include bottle roll and column tests.
Phase one will evaluate the project’s amenability to heap leach extraction, including potential metal recoveries, leach kinetics, and reagent consumption across the property. Phase two will focus on assessing conventional extraction methods, including carbon-in-leach and gravity flotation processes.
As part of the first phase, five column tests covering composite, representative samples from the Tyee and the Herman areas will be completed, including newly discovered mineralisation between zones one to four in Tyee.
In conjunction, 20 simple bottle roll tests on the composites assembled from reverse circulation drilling will be performed to determine cyanide solubility of gold mineralisation from a variety of geologic domains throughout the project area.
The 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.
Results from initial bottle roll tests are expected by May 2026.
Kappes, Cassiday & Associates (KCA) will be performing the 2026 testwork. KCA specialises in all aspects of heap leaching, cyanide processing, laboratory testing, project feasibility studies, engineering design, construction and operations management.
Further, Provenance Gold’s CEO Rauno Perttu will be retiring from his role and Rob Clark will assume the role as CEO while Perttu will remain as Chairman.
The company has also appointed Etienne Gouin-Proulx as director of the company effective immediately. Gouin-Proulx is a chartered financial analyst and a professional engineer with experience in project evaluation, mergers and acquisitions, and public markets.
Provenance Gold is a precious metals explorer focused on the Eldorado Project located in eastern Oregon. Eldorado is a district-scale land position totalling 7,915 acres. The project benefits from nearby infrastructure, road accessibility and local and federal support.
