Freegold Announces Positive Metallurgical Results from Golden Summit






  • An average gold recovery of 77% from eight composites using conventional processing techniques – gravity and CIL (carbon-in-leach)
  • 97% using gravity + flotation.
  • A flowsheet of gravity-flotation-CIL on reground concentrate yields 72% gold recovery along with a high mass desulfurized tailings stream
  • Further optimization studies are underway.


Freegold Ventures Limited (TSX: FVL) (OCTQX: FGOVF) is pleased to announce positive results based on the initial metallurgical test work completed from the 2020 – 2022 drill program. The program’s objectives were:

  • Determination of gold recovery and gold deportment to products using standard and commercially employed mineral processing unit operations
  • Initial environmental assessment of process tailing stream(s)
  • Characterization of gold losses to focus ongoing metallurgical programs to optimize the flowsheet design.


Eight drill core composites representing various locations and grades within the Dolphin/Cleary areas were generated using continuous drill intervals selected to represent potential mill feed. (See map below for hole locations.) The drill hole and interval selections encompassed the three primary gold-hosting lithologies. Results demonstrate that a significant portion of the mineralization is non-refractory and amenable to conventional processing techniques. The composites were prepared using laboratory assay rejects of fresh rock intervals well below the existing oxide cap at Golden Summit. The eight drill hole composites used 1,192m of drill intercepts representing 587 continuous mineralized intervals with over 5,100kg of material.  Results from individual holes demonstrate recoveries up to 87.5%.  The average recovery from the eight composites was 77% using gravity and CIL. Recoveries increased to an average of 97.5% where gravity + flotation were utilized. Environmental characterization using standard ABA protocols gave a NP:AP ratio of 85:1 on the flotation tailings stream, which would classify them as non-acid generating.

The drilling success at Golden Summit since 2020 has been truly remarkable. It has significantly increased the resource and enhanced the project’s potential. These positive metallurgical results further solidify Golden Summit’s potential. The current pit-constrained resource at Golden Summit hosts both an oxide and a primary resource. The oxide resource is contained within the top 70% metres. Previous column testwork on the oxide material demonstrated that heap leach gold recoveries of 85% can be achieved within two weeks.

Following the February 2023 resource update, Freegold conducted an additional 22,000 meters of drilling in 37 holes within the resource area. A significant increase in visible gold was observed in the drill core compared to previous programs, particularly in the western part of the resource.  An updated mineral resource report based on the 2023 drilling is expected later this month. The success of the 2023 drilling program has set the stage for an even more exciting 2024 program. The upcoming phase will focus on optimization, testing the 2km gold-in-soil geochemical anomaly to the west, drilling large diameter (PQ) holes to guide further and optimize metallurgical recoveries, and modelling before economic studies commence. Freegold has postponed the economic studies to investigate the potential for higher grades in the western extension and to conduct additional metallurgical test work, as both could significantly impact the project’s economics. The primary areas of focus in the next phase of metallurgical test work are:

  • Comminution studies using half PQ core
  • Flotation concentrate oxidation pre-treatment prior to CIL
