Gold Recoveries Increased to Over 80%; Ongoing Metallurgical Work Produces a High-grade Copper, Gold and Silver Concentrate for the Goldstorm Deposit at Treaty Creek, Golden Triangle Region, Northwestern B.C.

Highlights from the recent follow-up metallurgical testing on the Lower CS-600 sub-domain included a significant increase in gold recovery:
-
Flotation recoveries and gold extraction within the Lower CS-600 sub-domain totaled up to 85.8% copper, 80.2% gold, and 58.1% silver.
-
Flotation testing consistently achieved a high-grade copper concentrateof 30.3% copper, 36.5 g/t gold and 99.8 g/t silver.
In comparison, highlights from the previous metallurgical testing released October 24, 2024 [Teuton Resources release October 25 2024] on the Lower CS-600 sub-domain included:
-
Flotation recoveries within the Lower CS-600 sub-domain totaled up to 88.1% copper, 63.8% gold, and 51.3% silver.
-
Flotation testing confirmed that a high-grade copper concentrate with significant quantities of gold can be produced from the Lower CS600 sub-domain, that exceeds 29% copper with significant gold and silver grades of 33 g/t and 96 g/t, respectively.
Commenting on the results, Ken Konkin, President & CEO of Tudor Gold stated, "We are very pleased with our second set of flotation test results obtained from the lower portion of the CS-600 Domain (CS-600L). We estimate more than 50% of the CS-600 Domain is located within the lower portion (the CS-600L sub-domain). These latest results compared favorably with the first locked cycle test we announced on October 24, 2024. With a simple rougher-cleaner flotation process we are consistently able to produce an exceptionally clean, high-grade copper/gold concentrate with excellent metal recoveries and, significantly, we were able to recover more gold during the most recent metallurgical work with an additional leaching step. We conducted testing on the flotation tailings and pyrite concentrates by simply leaching these with cyanide. This added a substantial amount of gold, which increased the combined gold recovery to just over 80%. Our metallurgical team believes that continued fine-tuning of the process may continue to yield higher recoveries. Several tests demonstrated that higher gold recoveries were associated with finer grinds. These reported recoveries utilized a grind size of -75 microns. The CS-600L sub-domain is located in the same area that hosts the newly discovered Supercell-1 (SC-1) high-grade gold complex. Our technical team is currently completing elements of our next permit application to include the construction of an exploration ramp designed to intersect the area immediately adjacent to the CS-600 Domain and directly above the newly discovered SC-1 high-grade gold structures. The proposal is to construct a three-kilometer-long exploration ramp collared from our Lower Camp area that will allow us to more efficiently drill test the SC-1 complex. This is an important aspect of our Treaty Creek Project, as the added possibility of defining a high-grade, multi-million-ounce gold deposit would greatly enhance the economic potential of the project, since it would provide us with a much smaller Capex target to start the mine process."
The follow-up flotation program on the Lower CS-600 sub-domain focused on optimizing gold recovery. In addition to using the typical copper flowsheet to produce the saleable copper concentrate, cyanide leach of the flotation tails was investigated. Additionally, evaluation of a sequential copper-pyrite flowsheet was conducted, and cyanide leach of the pyrite concentrate at various grind sizes carried out. Further testwork to investigate the upside potential of gravity concentration as well as optimization of flotation and leach conditions has been recommended to further improve copper and gold recoveries.
Remaining samples from the original PJ-5434 and PJ-5473 CS600L testwork were used to further advance this gold optimization testwork. To maximize material, the remaining samples were blended from the two previous testwork campaigns and therefore cannot be taken as a direct comparison to the locked cycle testwork, however, provide a close comparison for discussion.

Metallurgical Test Work and Results:
Initial metallurgical testing carried out at Blue Coast Research, under the supervision of Fuse Advisors Inc. continued to demonstrate that a high-grade copper/gold concentrate could be produced from the Lower CS-600L domain along with increased gold recoveries through further processing of the flotation tails.
The following approaches to improving gold recovery were conducted:
-
Optimization of copper and sequential copper-pyrite flotation circuit for gold;
-
Evaluation of cyanide leach on the copper rougher flotation tails for gold extraction;
-
Evaluation of cyanide leach on the pyrite concentrate produced from sequential copper/pyrite flotation
Flotation Optimization:
A number of batch roughers tests were carried out to understand if gold recovery could be improved in the copper roughers or through sequential pyrite flotation. Further cleaner tests were conducted to understand the impact downstream. A summary of the tests completed can be found in Table 1.
-
F2/F3/F7 - Optimize gold recovery into the pyrite concentrate by investigating some of the following parameters: Collector dosage, flotation time, copper sulphate addition
-
F4 - Investigate the impacts of floating more pyrite into the copper concentrate.
-
Natural pH in the rougher circuit, collector dosage
-
-
F6/F8 - Cleaner tests to investigate how pulling additional pyrite into the rougher concentrate effects gold and copper cleaning

Initial results indicated there was notable variability in the copper circuit gold recovery, however, the pyrite circuit was consistent at recovering 87% gold to copper rougher and pyrite rougher. The bulk copper rougher at a natural pH was able to achieve the same 87% gold recovery, however, had negative implications in the cleaning circuit, resulting in reduced overall copper and gold recoveries.
Copper Rougher Flotation Tails Leach:
The copper rougher flotation tails leach flowsheet follows a typical copper flotation circuit configuration, with standard copper flotation reagents, as seen in Figure 1. The batch flotation tests achieved recoveries of 85.8% copper, 66.3% gold, and 58.1% silver into a concentrate with grade 30.3% copper, 36.5 g/t gold.
The copper rougher flotation tails were subjected to cyanide leach testwork, resulting in 53% gold extraction. The flotation rougher tailings contained 26% of the total gold, yielding a total gold extraction of 13.9%. The combined gold flotation recovery plus cyanide extraction totaled 80.2%.

Copper-Pyrite Sequential Flotation/Pyrite Concentrate Leach:
An additional sequential copper/pyrite flowsheet was evaluated to recover additional gold from a pyrite concentrate, shown in Figure 2. Numerous tests were performed which demonstrated an average of 15-20% gold recovery to the pyrite concentrate. The pyrite concentrate was reground to 10 microns and subjected to cyanide leach, extracting 42-48% gold. This provided an additional gold extraction of 7-8% for a total gold recovery and extraction of 67-71%.
