Rzolv signs Arizona leach demo agreement

RZL · Price
Executive Summary
- Rzolv Technologies Inc. has signed an operating agreement with Environmental Research and Development (ERD) to deploy its proprietary non-cyanide technology at ERD’s mine site in Arizona.
- The agreement involves processing mineralized fine material via an agitated tank leach configuration, starting with a nominal throughput of 50 tonnes per day, with potential expansion to 100 tonnes per day.
- ERD will supply approximately 35% of typical run-of-mine material (prescreened to minus two millimetres), and ERD will pay Rzolv 50% of gross profits from the operation.
Key Details
- Parties: Rzolv Technologies Inc. and Environmental Research and Development (ERD).
- Technology: Rzolv’s proprietary, non-cyanide hydrometallurgical technology deployed in an agitated tank leach configuration.
- Location: ERD’s patented mine site in Arizona.
- Throughput: Initial operations at 50 tonnes per day of prescreened material (minus two millimetres); subject to validation, intended to increase to approximately 100 tonnes per day.
- Material Supply: ERD to supply postscreened (minus two mm) mineralized material, representing approximately 35% of typical run-of-mine material.
- Financial Terms: ERD pays Rzolv 50% of gross profits (defined as gross revenues less operating costs).
- Term: Initial two-year term.
- Conditions Precedent: Subject to receipt of all required operating permits and regulatory approvals, and continuing compliance with applicable laws and regulations as determined by the State of Arizona.
- Operational Scope: Rzolv will deploy and oversee gold processing systems, produce loaded carbon for off-site extraction, and evaluate operational performance.
- Environmental Controls: Fully contained, closed-loop process circuit; all process solutions captured, recycled, and managed on site; no discharge to surface or groundwater.
- Prior Testwork Context: Laboratory and bulk-scale testwork (100-tonne bulk sample) showed gold dissolution kinetics and recovery comparable to conventional cyanide-based systems, with higher dissolved gold concentrations than sodium cyanide under certain controlled conditions.
- Disclaimer: No mineral resources or reserves are being reported; results are based on specific bulk samples and may not be indicative of performance on other ore types.
Notable Quotes
- "This operating agreement represents an important step in advancing Rzolv from controlled testing into sustained, on-site operations... Advancing Rzolv's non-cyanide chemistry into an agitated tank leach configuration at an initial scale of approximately 50 tonnes per day is intended to generate additional operational data under representative conditions." — Duane Nelson, President and CEO, Rzolv Technologies.
- "We see this collaboration as an opportunity to evaluate an alternative processing technology on our material under real operating conditions. The phased approach allows both parties to assess performance at a meaningful scale before expanding throughput." — Steve Scott, President and CEO, Environmental Research and Development.
