Revival Gold returns 93% gold recovery purity from Beartrack-Arnett project in Idaho

The company combined 21 separate core samples to replicate the quality of high-grade ore found at Beartrack-Arnett

Preliminary results from Revival Gold Inc. (TSXV: RVG) (OTCQX: RVLGF) metallurgical testing on sulphide material returned gold recoveries of 93 per cent to concentrate from a composite sample grading 4.6 grams per ton gold.

The company announced the results on Wednesday from its third stage of testing from its Beartrack-Arnett Gold Project in Lemhi County, Idaho.

Revival’s objective with the program was to observe and evaluate the flotation performance of the high-grade sulphide material taken from Beartrack-Arnett to determine if it could yield a salable concentrate.

The company created a composite sample by combining 21 separate core samples to replicate the quality of high-grade ore found at Beartrack-Arnett.

Revival was able to produce a concentrate containing 50 grams of gold per metric ton with a relatively coarse grind size of 150 micrometers. This means that for every 100 units of ore processed, 8.9 units ended up as this high-grade concentrate.

This concentrate also contained 23 per cent of sulfur from the sulfide minerals, and they successfully recovered 98 per cent of the sulfur from these minerals.

“Today’s announced test results support a potential mill development concept that would involve the production and sale of concentrate rather than the construction of a complete onsite gold production facility for the Project,” said Hugh Agro, president and CEO of Revival Gold.

“This approach could greatly simplify and reduce the potential capital cost of developing a second phase mill operation at Beartrack-Arnett.”

Metallurgical testing programs are follow-up to previous programs

This year’s metallurgical testing program on the Beartrack-Arnett mill material was a follow-up on prior metallurgical test programs completed in 2018 and 2019.

The program was undertaken through a sequence of distinct steps designed to ensure precision and efficacy. The program started with an analysis of geological factors such as lithology, ore grade, depth, and oxidation levels to inform the selection of composite samples. This comprehensive analysis guided the team’s choices, ensuring the chosen samples accurately represented the target conditions.

Afterwards, the team initiated the preparation phase, involving the meticulous assembly of a composite sample. This composite sample was created by combining material from 21 individual samples of coarse reject material obtained from core drilling activities in the Joss area during 2022, providing a representative basis for further work.

Revival performed batch-scale variability testing to optimize processing methods. This step allowed for the identification of the optimal grind size, refinement of the flotation process for both rougher and cleaner stages, and determination of precise reagent dosages needed for efficient operations.

The team also executed locked cycle flotation testing, which entailed recycling cleaner tailings through seven cycles. This iterative approach provided valuable insights into the performance and reliability of the processing methods, ultimately enabling the team to achieve the desired outcomes with a high degree of confidence and precision.

Idaho offers high value gold investment

The global demand for gold as a safe-haven asset and its diverse industrial applications make it a resilient and potentially profitable investment, with Idaho positioned as a promising frontier for gold exploration and mining ventures.

A few gold companies operating in Idaho include Hecla Mining Company (NYSE: HL) in the Coeur d’Alene Mining District, and Perpetua Mining (NASDAQ: PPTA) (TSX: PPTA), which operates the Stibnite Gold Project. Additionally, NevGold Corp (TSXV:NAU) (OTCQX:NAUFF) (Frankfurt:5E50), which recently completed its Mineral Resource Estimate for its Nutmeg Mining gold project. The estimate replaces the previous estimate, compiled by GoldMining Inc. (TSX: GOLD) (NYSE: GLDG) before NevGold’s acquisition of the property in 2022.
