RZOLV Reports Preliminary Positive Laboratory Results for Sequential Copper and Gold Extraction from Selected Low-Grade Copper-Gold Samples
Pre-revenue hydrometallurgy developer advancing non-cyanide gold extraction with pilot validation and recurring capital raises.
Executive Summary
- RZOLV Technologies announced preliminary laboratory results for sequential copper and gold extraction from low-grade copper-gold samples using its proprietary RZOLV platform.
- Direct leaching achieved calculated-head gold recoveries of 82.3% to 94.8% and copper extraction of 71% to 80% via pre-treatment.
- Sequential pre-treatment allowed copper to be extracted into separate liquors while gold remained in the solid residue, with no gold detected in the pre-treatment liquors.
- Reagent additions were 27% to 64% lower in pre-treated tests compared to direct-leach tests.
- Testing was conducted at laboratory scale using bottle-roll tests on two composite samples under unoptimized conditions.
- Each condition was generally tested once with no confirmed duplicates.
- Future work will focus on repeatability, process optimization, scale-up evaluation, and recovery of both metals into saleable products.
Material Impact
- The release provides incremental technical validation of a sequential processing pathway but does not alter the company's commercial timeline or financial profile.
- Results remain at the bench-scale, unoptimized, and single-run stage, meaning they do not yet demonstrate commercial viability or predictable scale-up.
- No revenue, margin, or cash flow impact is realized from this update.
- The announcement does not change the company's immediate capital requirements or going concern status.
