American Creek's JV Partner Tudor Gold Announces Positive Metallurgical Testing Results for the Goldstorm Deposit at Treaty Creek, Located in the Heart of the Golden Triangle, Northwestern British Columbia
Rhea-AI Summary
American Creek Resources announces positive metallurgical test results from the Goldstorm Deposit at Treaty Creek Project. The Lower CS-600 sub-domain testing showed impressive flotation recoveries of up to 88.1% copper, 63.8% gold, and 51.3% silver. The tests produced high-grade copper concentrate exceeding 29% copper with gold and silver grades of 33 g/t and 96 g/t respectively. Previous testing on gold-dominant domains 300H and DS5 demonstrated gold recoveries exceeding 94% for the Albion process and 98% for pressure oxidation tests. The lower portion of CS-600 has sufficient volume to mine and process 40,000 tpd over 17 years.

Cardston, Alberta--(Newsfile Corp. - October 25, 2024) - American Creek Resources Ltd. (TSXV: AMK) ("the Corporation" or "American Creek") is pleased to announce that project operator and JV partner Tudor Gold ("Tudor") has given an update to ongoing metallurgical testwork on the Goldstorm gold, copper and silver deposit, located on the Treaty Creek Project situated within the Golden Triangle of British Columbia.
Highlights from the Metallurgical Testing on the Lower CS-600 Sub-Domain include:
- Flotation recoveries within the Lower CS-600 sub-domain totaled up to
88.1% copper,63.8% gold, and51.3% silver; - Flotation testing confirmed that a high-grade copper concentrate with significant quantities of gold can be produced from the Lower CS-600 sub-domain, that exceed
29% copper with significant gold and silver grades of 33 g/t and 96 g/t, respectively;
The flotation program uses a typical copper flowsheet to produce the saleable copper concentrate mentioned above. Further flotation testwork is ongoing to produce a separate pyrite concentrate containing gold and silver. The positive results from flotation, in conjunction with previous oxidative leaching methods (such as Pressure Oxidation or Albion), continue to support the previously reported gold recoveries of
Commenting on the results, Ken Konkin, President & CEO of Tudor Gold, stated, "We are very pleased with the results obtained from the locked-cycle flotation tests from this phase of metallurgical testing on material from the lower portion of the CS-600 Domain (CS-600L). We estimate more than
Our concept is to focus on the high-grade SC-1 to study the possibility of extracting as much high-grade gold as possible while potentially building out the infrastructure to access the CS-600L area. The plan is to utilize the same workings from the Supercell complex to access the CS-600 domain. These latest results from the CS-600L Domain significantly de-risk the Goldstorm project with respect to metallurgical characteristics of the copper-gold mineralization and will be utilized in a future Preliminary Economic Assessment (PEA).
Additionally, two gold-dominant domains, 300H and DS5, have demonstrated high gold recoveries from previous oxidation/cyanidation tests, with results exceeding

Metallurgical Test Work and Results:
Recent metallurgical testing carried out at Blue Coast Research, under the supervision of Tad Crowie, P. Eng. of JDS Energy & Mining Inc. demonstrated that a high-grade copper concentrate could be produced from the Lower CS-600 sub-domain. The locked cycle test achieved recoveries of
The current flotation flowsheet follows a typical copper flotation circuit configuration, with standard copper flotation reagents, as seen in Figure 2. The primary grind in the current testwork has been reduced from a P80 of 120 µm used in the previous testwork program to a P80 of 75 µm allowing for a higher overall recovery of copper than has been previously achieved. The gold recoveries have achieved similar results to previous flotation testwork.

A rougher concentrate regrind target of P80 of 30 µm allowed the production of a high-grade copper concentrate, exceeding
The locked cycle test results for the combined products of last 3 cycles of the test (cycles 4, 5, and 6) can be found in the table below. The locked cycle test achieved stability after the first 2 cycles, which demonstrates that the flowsheet is stable, as well as validating the test results.

The high copper concentrate grade, along with high levels of gold and silver, achieved in this test suggests that there are opportunities to pull the circuit harder to increase overall metal recovery.
