Independent CTRI Testing Indicates RZOLV Exhibits Dramatically Lower Acute Trout Toxicity Than Cyanide Reference

Executive Summary

• RZOLV Technologies released an ecotoxicity report showing its reagent has a dramatically lower acute aquatic toxicity than cyanide (≈57,000‑fold higher LC50 for rainbow trout).
• The findings support the company’s claim that its non‑cyanide hydrometallurgical platform offers a meaningful environmental advantage and could be a safer substitute in metal recovery operations.
• Management highlighted the results as an important technical milestone toward commercializing the lower‑toxicity reagent across mining and resource‑recovery projects.

Key Details

• Test Organisms & Methods: Acute toxicity evaluated on rainbow trout (Oncorhynchus mykiss) and water flea (Daphnia magna) using Canadian reference methods SPE 1/RM/13 and SPE 1/RM/14.
• Toxicity Comparison: Nominal 96‑hour LC50 for RZOLV was ~57,000 times higher than the cyanide reference value; cyanide reached lethal endpoint at roughly 1/57,000th the concentration required for RZOLV.
• Interpretation Caveats: Differences in matrix pH, hardness, alkalinity, dissolved oxygen, temperature, and other water‑chemistry factors may affect observed toxicity; comparison is directional, not a head‑to‑head study under identical conditions.
• CEO Quote: Duane Nelson (President & CEO) stated the report adds an important environmental data point to RZOLV’s value proposition and validates its potential as a lower‑toxicity platform for precious and critical metals recovery.
• Strategic Implication: Lower‑toxicity reagent could reduce permitting, water‑management, detoxification, and environmental‑risk burdens, providing commercial advantage in jurisdictions with strict environmental regulations.
• Future Plans: Company intends to continue advancing, validating, and commercializing the technology, acknowledging that laboratory results may differ under field conditions.

Notable Quotes

“This report adds an important environmental data point to the RZOLV value proposition… we believe these results further validate RZOLV's potential as a lower‑toxicity hydrometallurgical platform for modern mining and resource recovery.” – Duane Nelson, President & CEO

Materiality Assessment: Material – Positive (the data materially supports the company’s core technology claim and could influence market perception and future commercial adoption).
