About RZOLV Technologies Inc.

RZOLV Technologies Inc. is a clean-tech company developing innovative, non-toxic solutions that aim to transform gold extraction and mine-site remediation. The Company's flagship product, RZOLV, is a proprietary water-based hydrometallurgical formula that provides a sustainable, safe alternative to sodium cyanide for the dissolution and recovery of gold.

Cyanide has been the industry standard for more than a century, yet its toxicity has resulted in bans or restrictions across multiple jurisdictions, along with significant permitting, handling, and ESG challenges for mining companies. RZOLV delivers comparable performance and cost metrics to cyanide while offering a non-toxic, reusable, and environmentally sustainable profile, enabling gold extraction in regions, ore types, and project settings where cyanide use is impractical, prohibited, or socially unacceptable.
