BRIEF
Fender Geophysics conducted a Dipole-Dipole Induced Polarisation (DDIP) survey for Kalo Gold www.kalogoldcorp.com from April-May 2021 over their Qiriyaga Hill Prospect. The Qiriyaga Project survey area is located approx. 30km east of Labasa on the island of Vanua Levu in Fiji. The underlying Qiriyaga Zone is a 2.5km long mineralization trend identified by anomalous gold in soil geochemistry and trenching.
CLIENT REQUIREMENT
The survey comprised a total of 17 roughly NW-SE oriented DDIP lines of 1600m to 2400m length. Acquisition parameters comprised 100m dipoles using a dipole-dipole array, reading down depths of up to 400m.
OUTCOME
Conditions on site were reasonably good with dense vegetation (ex sugar cane fields) in gently sloping terrain. Some areas were steeper and more rugged, especially in the south-east of the survey area. Site access on foot was good and vehicle access was possible in some places. A total of 273 stations were recorded at an average of 8.5 stations per production day.
Fenders’ IP survey more than doubled the number of drill targets in Qiriyaga Zone. The IP survey identified three additional large shallow-to-moderately deep chargeability anomalies broadly coincident with gold geochemical anomalies and silica-clay alteration. The three new targets in Qiriyaga Zone have not been drill-tested but indicate the possible presence of mineralized bodies beyond the limits of previous drilling.
Fred Tejada, Kalo Gold Chief Executive Officer, commented: “We are very excited about the results from the IP survey, indicating that the Qiriyaga Zone has the potential to be a large system, and the Qiriyaga Hill Deposit could be just the tip of the iceberg. Multiple large high priority targets have been identified from the IP survey and the vast majority have never been drill tested or they occur beyond the limits of historical drilling”
