C29 Metals Limited (ASX: C29) has announced the identification of multiple high-priority, multi-commodity targets at its Southern Kazakhstan tenement, following the completion and interpretation of a comprehensive helicopter-borne geophysical survey.
Conducted by global geophysical services provider Xcalibur Multiphysics, the survey combined electromagnetic (EM), magnetic, and radiometric data to deliver compelling results, further refining the company’s understanding of the area’s potential for copper, gold, lead, zinc, silver, uranium, and IOCG-style mineralisation.
The survey covered the company’s 214-square-kilometre southern tenement (#2786-EL), revealing several new targets, particularly in zones adjacent to and north of the Rodnikovoe lead-zinc-silver mine.
This mine, located approximately 40 kilometres southwest of Aksuyek, previously produced over 52,000 tonnes of lead at grades of 7.11% Pb, 1.52% Zn, and 12.3 g/t Ag between 2010 and 2017.
The newly identified targets are characterised by coincident EM conductivity, magnetic, and K/Th radiometric anomalies, often associated with structural intersections and intrusions typical of IOCG and porphyry-style systems.
A major central anomaly, distinguished by multi-layered geophysical evidence, has been prioritised for follow-up fieldwork and drilling later this year.
Commenting on the 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.”
Interpretation of the data has highlighted strong structural controls within the tenement, with northeast-southwest trending faults connecting the historic Bota Burum uranium mine to Rodnikovoe, forming a regional mineralisation corridor.
The central anomaly is particularly promising, marked by high magnetic intensity (800nT), radiometric K/Th and uranium enrichment, surface conductivity from early-time EM data, and evidence of structural intersections and intrusive centres.
This geophysical signature supports the working model of IOCG-style mineralisation, drawing parallels to globally significant deposits such as Olympic Dam and Prominent Hill.
C29’s 2025 field program is already underway, focusing on detailed mapping and surface sampling of geophysical anomalies using in-field XRF, mapping alteration styles such as hydrothermal breccias and potassic/phyllic zones, and advancing drill targeting through inversion modelling of all collected geophysical and geochemical data.
Drilling on priority targets is expected to commence later this year.
