Altair Minerals (ASX:ALR) announced a breakthrough at its South Oko Project, identifying two compelling geochemical drill targets that suggest the presence of a structurally controlled gold system.
Recent extensional soil sampling programmes have successfully defined a second major target, designated as W3, which joins the previously identified W1 anomaly along the prolific Oko Shear Contact.
The W1 target remains the largest coherent soil anomaly found to date at the site, boasting a strike extent of approximately 1.6 km with gold concentrations exceeding 100 ppb.
However, the discovery of the W3 target is particularly notable for its geological implications. Spanning roughly 2.1 km, the W3 anomaly was identified directly atop duricrust—a typically barren, hard surficial layer that usually masks underlying mineralisation.
This represents the first time a clear geochemical response has been generated through the duricrust at South Oko, indicating a highly prospective and "blind" target beneath the surface cover.
Both targets align with geophysical highs in chargeability and resistivity, further strengthening the case for gold deposits.
The company has completed 1.9km of trenching and is awaiting assay results from 145 soil samples and 40 auger holes. Infrastructure upgrades are also underway at North Peters Camp to support the next phase of development.
Drilling operations, including RAB and diamond drilling at both SOKO and North Peters, are scheduled to commence this April as the company moves to test these high-priority zones.
At the time of reporting, Altair Minerals’ share price was $0.025.
