RZOLV Technologies Signs Operating Agreement with Environmental Research and Development to Advance Agitated Tank Leach Demonstration Facility in Arizona

Executive Summary

• RZOLV Technologies Inc. entered into a two‑year operating agreement with Environmental Research and Development (ERD) to pilot its non‑cyanide hydrometallurgical technology at ERD’s patented mine site in Arizona.
• The initial demonstration will process up to 50 tonnes per day of pre‑screened mineralized material, with the potential to scale to ~100 t/d pending successful performance validation.
• Under the agreement, ERD will supply the feedstock and pay RZOLV 50 % of gross profits (gross revenues less operating costs).

Key Details

• Agreement Scope: Deploy RZOLV’s proprietary non‑cyanide reagent in an agitated tank leach configuration; produce loaded carbon for off‑site gold extraction; evaluate leach behavior, solution management, and operational performance at scale.
• Initial Throughput: 50 tonnes per day of material screened to ≤2 mm; possible increase to ~100 t/d after validation.
• Feedstock Characteristics: Post‑screened mineralized material representing ~35 % of typical run‑of‑mine ore from ERD’s Arizona mine.
• Term & Conditions: Two‑year term, contingent on receipt of required permits and regulatory approvals in Arizona; closed‑loop process with all solutions captured and recycled on‑site; no discharge to surface or groundwater.
• Financial Arrangement: ERD will remit 50 % of gross profits (gross revenues less operating costs) to RZOLV for the duration of the agreement.
• Technical Background: Prior laboratory and bulk‑scale tests (including a 100‑tonne bulk sample) showed gold dissolution kinetics comparable to, or exceeding, conventional cyanide leaching under identical conditions.
• CEO Commentary (RZOLV): Emphasized transition from controlled testing to on‑site operations; noted that results will inform operating costs, permitting considerations, and potential scale‑up, but no assurance of commercial viability.
• CEO Commentary (ERD): Highlighted the collaboration as a means to evaluate alternative processing technology under real conditions with a phased approach before any throughput expansion.
• Environmental Controls: Fully contained, closed‑loop leach circuit; solutions captured, recycled, and managed on‑site; chemical system lacks acute toxicity typical of cyanide, facilitating standard industrial handling protocols.
