12 May 2025 | C29 Metals Limited (ASX: C29) (“C29” or the “Company”) is pleased to announce the identification of multiple multi-commodity targets , which are considered high-priority, following the completion and interpretation of a helicopter-borne electromagnetic (EM), magnetic, and radiometric geophysical survey at its Southern Kazakhstan tenement.
Completed by global geophysical services provider Xcalibur Multiphysics, this survey has delivered compelling results and further refined the Company’s understanding of potential copper, gold, lead, zinc, silver, uranium and IOCG-style mineralisation within the project area of its southern tenement (#2786-EL).
Highlights:
-
Multiple new targets identified through EM, magnetic and radiometric data across the 214km² tenement.
-
High-priority zones adjacent to and north of the Rodnikovoe lead-zinc-silver mine, which previously produced over 52,000 tonnes of lead (7.11% Pb, 1.52% Zn and 12.3 g/t Ag).
-
Coincident EM conductivity, magnetic, and K/Th radiometric anomalies associated with structural intersections and intrusions, typical of IOCG and porphyry-style systems.
-
A major central anomaly identified showing multi-layered geophysical evidence, now prioritised for follow-up fieldwork and drilling.
Commenting on the recent development, C29 Managing Director, Shannon Green stated: “Since Rob commenced, he has hit the ground running and enabled the Company to complete the geophysical interpretations over the southern tenement and follow up with initial ground truthing field works. The geophysics program has identified several exciting target areas for us. The next step geological field works have now commenced that are intended to lead to some exciting drilling targets that we will begin testing later in the calendar year”.
Strategic Geological Insights
Data interpretation highlights strong structural controls within the tenement, with NE-SW trending faults connecting the historic Bota Burum uranium mine to Rodnikovoe, forming a regional corridor of mineralisation. The central anomaly identified is especially promising, marked by:
-
High magnetic intensity (800nT),
-
Radiometric K/Th and uranium enrichment,
-
Surface conductivity from early-time EM data,
-
Structural intersections and interpreted intrusive centres.
This multi-layered geophysical signature supports the working model of IOCG-style mineralisation, similar to globally significant deposits like Olympic Dam and Prominent Hill.
Next Steps in Kazakhstan
C29’s field program for 2025 is currently underway, with its focus primarily on:
-
Detailed mapping and surface sampling of geophysical anomalies using in-field XRF.
-
Mapping alteration styles such as hydrothermal breccias and potassic/phyllic zones.
-
Advancing drill targeting through inversion modelling of all collected geophysical and geochemical data.
-
Drilling is expected to commence on priority targets later this year.
