Gold Exploration

Pinpoint gold at the edge of detection

Successful exploration hinges on detecting subtle geochemical signals—often faint and close to detection limits. Ultra low detection thresholds are essential for confidently pinpointing prospective targets and expanding exploration into new, challenging terrains where mineral indicators may be scarce. Our gold exploration methods deliver complete gold recovery combined with detection limits in the parts-per-trillion (ppt) range, revealing hidden geochemical footprints that traditional techniques overlook. This enhanced sensitivity provides a clearer understanding of background levels, empowering more precise vectoring toward mineralised systems and driving discovery with greater confidence.

Super trace gold detection for confident discovery

Engineered for precision, Au-NANO51™ and AuME-NANO™ deliver super trace detection limits and near-total gold recovery, making them ideal for unveiling subtle geochemical signals that guide successful exploration. Au-NANO51™ reports gold only, while AuME-NANO™ extends capability by also reporting key pathfinder elements. They offer a high-confidence approach to anomaly detection, empowering more informed decisions from the earliest stages of discovery. Ideal for low-level gold anomalies, this suite is optimised for super trace detection—up to 250 ppb gold—and is not intended for ore-grade material.
