Rainbow

  • Project Size: 1,225 hectares
  • Reduced Intrusion Related Gold System
  • Ground magnetics reveal alteration signature across 3 x 2 kilometre area

The Rainbow project covers a gold and pathfinder element soil anomaly associated with surface alteration caused by a recently discovered intrusion, thought to belong to the mid-Cretaceous Tombstone Plutonic Suite. Other Tombstone-related gold deposits within the Tintina Gold Belt include Fort Knox (~11 million ounces Au), and Eagle (~4.8 million ounces Au).The property includes a northwest zone with anomalous gold in soils to 0.93 g/t Au, silver in soils exceeding a 100 g/t Ag assay limit, and anomalous bismuth, tungsten and antimony. Theland position also covers a 3 km magnetic signature extending eastward from the soil anomaly.

Grid soil geochemistry completed over the property revealed a 1 km by 300 m zone of high gold values (to 1.27 g/t) accompanied by anomalous bismuth, tellurium and tungsten flanked by zones of anomalous arsenic, antimony and silver. This geochemical anomaly corresponds to the eroded edge of a 3×2 kilometre magnetic anomaly. Prospecting returned shear-hosted sulphide-bearing outcrop samples grading 4.1 g/t Au and locally-derived angular quartz float samples running 7.98 g/t Au. The magnetic anomaly reveals the potential size of the alteration system, and stream geochemistry anomalies that are 2.5 kilometres from the soil anomaly suggests that mineralizing fluids may have travelled at a similar scale.

A program of drone surveying, geochemical sampling and structural mapping is planned to establish suitable drill targets on the Rainbow property.

Figure 1: Intense, zoned, multi-element soil anomaly associated with eroded exposures of a hornfelsed zone around newly-discovered intrusive rocks at Rainbow. High spatial correlation between gold and bismuth, with anomalous antimony and arsenic peripheral to the gold zone is similar to zoning observed in known reduced intrusion related gold systems such as Kinross Gold’s Ft. Knox deposit in Alaska.
