Independence Gold Reports Metallurgy Results from the 3Ts Project, BC

Vancouver, British Columbia--(Newsfile Corp. - September 10, 2025) - Independence Gold Corp. (TSXV: IGO) (OTCQB: IEGCF) (the "Company" or "Independence") is pleased to announce updated metallurgical recovery results from the 3Ts Project. Located approximately 185 kilometres southwest of Prince George, British Columbia, the 3Ts Project comprises thirty-one mineral claims covering approximately 35,486 hectares in the Nechako Plateau region. The project is situated 16 km southwest of Artemis Gold Inc.'s Blackwater Mine and covers a low-sulphidation epithermal quartz-carbonate vein district within which at least nineteen known mineralized veins, ranging from 50 to over 1,100 metres in strike length and true widths of up to 32 m have been identified.

Metallurgical testing was conducted by Base Metallurgical Laboratories Ltd. in Kamloops, BC., and returned positive results that further confirmed previous metallurgical testing. These tests evaluated a three-stage process including gravity concentration, flotation, and cyanide leaching.

Sample Selection and Preparation
Composite samples comprised of mineralized vein material were collected from drill core recovered during the 2024 to 2025 program and were selected to test mineralized veins at depth as well as two new veins (Johnny and Larry) that were intersected during the recent drill program. The three tests were:

• Tommy Vein "Deep"
  • 3TS-24-27 from 361.39m to 429.96m*, including grades up to 13.46 g/t gold and 119.0 g/t silver (see dated January 20, 2025)
• Johnny Vein System
  • 3TS-25-05 from 13.59m to 85.50m*, including grades up to 19.95 g/t gold and 176.0 g/t silver (see dated March 20, 2025)
• Larry Vein
  • 3TS-27-07 from 179.00m to 198.40m*, including grades up to 20.36 g/t gold and 333 g/t silver (see dated March 26, 2025)

(* mineralized samples selected from interval rather than a complete run through these lengths)

Gravity, Floatation and Leaching Test Results
Composite samples were subjected to three testing stages; gravity, gravity and floatation, and gravity, floatation and cyanide leaching (see below for methodology and detailed results for each stage). On average across the three composites, the full flowsheet yields program-level averages of roughly 92% gold and 90% silver.

These results are consistent with, and in some cases approach or exceed, historical recoveries reported in 2021, which included 93.9% gold and 92.4% silver recovery for the Tommy Vein, and up to 97.9% gold and 95.5% silver recovery for the Ted-Mint Vein (see dated March 4, 2021). The recoveries further validate the potential processability of the 3Ts mineralized material across new veins and at depth.

The table below shows recoveries for the three-stage tests on each of the vein composites:

 
"We are pleased to receive the latest results from the metallurgical testing," stated Randy Turner, President and CEO of Independence Gold. "These results give further confidence in previous recoveries conducted using vein material collected from the untested Larry and Johnny veins, as well as a Tommy vein sample that was taken at a significant depth. These results strengthen the viability of the 3Ts Project to support future resource growth and potential economic development."

Wildfire Update
continues to burn out of control, with an evacuation order still in place affecting the 3Ts Project camp. This wildfire has grown to more than 2,100 hectares in size, with crews and heavy equipment creating fire breaks around the camp; structure protection is currently in place taking steps to protect both the camp and the two core storage areas.

Notes for Disclosure

• All recoveries are based on bench-scale tests at 80% passing 100 µm; gravity values refer to Mozley concentrate reporting from Knelson concentrate; leach extractions are 72-hr bottle rolls on gravity or final flotation tails, as applicable. 
• Averages are program-level (three composites) and rounded to one decimal place for readability. Potential optimization steps (e.g., pre-oxidation, oxygen sparging, CN dosage) were identified for future work.

Methodology
Approximately 100 kg of crushed (3.35 mm) material from the 3Ts Project was delivered to Base Metallurgical Laboratories and combined into three master composites for testing. The program evaluated two conventional flowsheets at a primary grind of 80% passing 100 µm:

• gravity concentration followed by cyanide leaching of the gravity tails; and
• gravity concentration, flotation of the gravity tails, then cyanide leaching of the final flotation tails.

Gravity concentration used a Knelson concentrator with Mozley upgrade to produce a gravity concentrate and a gravity tail for downstream testing. Flotation was performed in a 4.4 L Denver D12 mechanical cell with air, using PAX 407 collector and MIBC frother at a pH of approximately 8.5. Cyanidation tests on appropriate tails were conducted at 40% solids with NaCN maintained at 1 g/L and pH 10.5-11 under air sparging, with monitoring to 72 hours.

For this testing the gravity concentrate, and flotation concentrate were assumed to be 100% extracted. Therefore, the overall extraction is based on a 100% assumed extraction for this stream.

Testing Results Per Stage
The following section shows results for composites during each stage of testing. The full metallurgical report will be available on the Independence Gold website.

Head Results:
The following table summarizes the assays results for both composite samples:

Gravity Separation:
A stand-alone gravity step recovered a meaningful portion from each master composite. Gold and silver reporting to the Mozley concentrate were:

 
Across all three composites, the program-level average gravity recovery was 17.4% gold and 8.6% silver.

Gravity and Leaching Tests:
Cyanidation leaching of the gravity tails was performed over a 72-hour process, which led to an overall increase in recoveries:
