URU Metals (LSE:URU) has completed a ground-based gravity survey over priority targets at the Zeb Nickel Project and reports strong correlation between the new gravity data and previously identified Spectrem airborne electromagnetic and magnetic anomalies.
The survey covered Targets 1 and 2, described as the highest-priority Spectrem anomalies, and was conducted on a 50 m x 50 m grid using high-precision CG5 gravimeters with data quality rated as "very good" after full Bouguer correction to refine the airborne datasets and better define potential drill targets for semi-massive nickel sulphide mineralisation.
"We are very encouraged by the results of the ground-based gravity survey, which show strong correlation with the airborne electromagnetic and magnetic datasets," Chief Executive Officer John Zorbas said.
The gravity results show a residual gravity high coincident with the Spectrem EM anomaly, an anomaly that extends beyond the EM footprint suggesting dense ultramafic rocks and/or sulphide accumulation zones, and a weak ~0.1 mGal gravity high in the southern portion of the northern EM anomaly that aligns with a first vertical derivative (1VD) magnetic anomaly.
URU says the higher-resolution ground gravity data improves confidence in the interpreted magmatic conduit system and provides a stronger technical basis for drill targeting.
A frequency-domain electromagnetic survey is expected to start shortly to further refine conductive responses and support final drill target prioritisation.
The Zeb Nickel Project is on the Northern Limb of the Bushveld Complex adjacent to the Ivanplats Platreef Project, which the company notes is expected to become one of the largest underground platinum-group metal operations once fully operational.
