Innovation Mining Achieves 99.6% Gold Recovery from High-Grade Alaska Black Sand Table Tails

Vancouver, BC – August 11, 2025 – Innovation Mining Inc. (“Innovation Mining” or the “Company”) is pleased to announce outstanding metallurgical results from bottle roll testing of high-grade gravity separation residues (“table tails”) sourced from a producing placer gold operation in Alaska. Using the Company’s proprietary RZOLV™ water-based, non-cyanide leaching reagent, gold recoveries of 99.6% were achieved within 7 days under ambient temperature conditions.

Test Material and Objective 

A 15 kg composite sample of black sand gravity tailings was collected from a 4,000 oz Au/year conventional placer (gravity) gold mine in Alaska. The objective was to determine the residual gold content, assess the leachability of this material, and evaluate process kinetics for potential large-scale recovery of gold values currently reporting to tailings.

Black sand tailings from shaker tables typically comprise magnetite, ilmenite, hematite, and other dense gangue minerals, with losses of ultra-fine or flat gold common due to hydraulic displacement during gravity concentration. The received sample was uncrushed, preserving its as-produced particle size distribution.

Bottle Roll Leach Program 

The material was subjected to a bottle roll test using RZOLV™ at 10% pulp density, with continuous agitation for 7 days. Fire assay analysis of both pregnant solutions and leach residues was used to determine extraction efficiency.

		Alaska Concentrates Bottle Roll Test - RZOLV
Time	Au Grade	Au Distribution	Au Grade
Days	ppm	%
0	0.0	_	-
1	8.0	19.90%	0.72
2	15.0	37.40%	1.35
3	23.6	58.80%	2.13
4	30.0	75.00%	2.71
7	40.0	99.61%	361.40
Tails		0.39%	1.42

Results confirmed a head grade of 361.4 g/t Au, with final residue assaying 1.42 g/t Au, representing >99% extraction efficiency. Leach kinetics demonstrated rapid gold dissolution in the first 72 hours, followed by near-complete extraction within the 7-day period.

Technical Significance 

These results indicate that RZOLV™ is highly effective in liberating and solubilizing gold entrained in dense mineral tailings from gravity recovery circuits. Given the high residual grades in the tested table tails, this process has the potential to unlock substantial additional value from what is conventionally considered waste.

The use of a non-cyanide, water-based lixiviant eliminates the need for hazardous chemical handling and aligns with regulatory requirements in environmentally sensitive jurisdictions such as Alaska.

Next Steps 

The Company is planning continued tests to minimize residence time by formula optimization and comprehensive agitated leach tests. Following these steps a pilot-scale test would be done to evaluate continuous leach performance, reagent consumption rates, and carbon adsorption/elution efficiency, with a view toward designing a modular recovery circuit for on-site deployment.
