Uru Metals upbeat on Zeb Project gravity survey results

(Sharecast News) - Uru Metals said on Monday that a ground-based gravity survey at its Zeb Nickel Project in South Africa had confirmed strong correlation with previously identified airborne electromagnetic and magnetic anomalies, improving confidence in potential drill targets.
The AIM-traded company said the survey was completed over Targets 1 and 2, which had previously been identified as the highest-priority anomalies from the Spectrem airborne electromagnetic survey.
It said the programme was carried out on a 50 metre by 50 metre grid using high-precision CG5 gravimeters, with data quality reported as "very good" after full Bouguer correction and processing.
Uru said the objective of the survey was to improve the resolution of airborne datasets and better define potential drill targets associated with semi-massive nickel sulphide mineralisation.
At Target 1, the Spectrem electromagnetic anomaly was found to correlate closely with a residual gravity high, confirming the target as both conductive and relatively dense.
The gravity anomaly also extended beyond the electromagnetic footprint, suggesting the presence of dense ultramafic rocks and possible sulphide accumulation zones.
Uru said the coincidence of conductivity and density was considered highly prospective for nickel sulphide mineralisation.
At Target 2, the company said a weak but distinct gravity high of about 0.1 milligal coincided with the southern part of the northern electromagnetic anomaly.
The feature also aligned with a first vertical derivative magnetic anomaly, reinforcing the validity of the target.
Uru said the response could represent a dense ultramafic unit such as a harzburgite pulse, while the combined conductive, dense and magnetic signature was also consistent with potential 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," said chief executive John Zorbas.
"The improved resolution of the ground survey provides greater confidence in the interpretation of these anomalies and enhances our ability to focus on the most prospective semi-massive and massive nickel sulphide targets.
"The responses observed at Targets 1 and 2 are particularly compelling, displaying the coincident conductive and dense signatures often associated with sulphide mineralisation.
"With the EM survey set to commence shortly, we look forward to further refining these targets ahead of drilling."
Uru said the results confirmed the presence of coincident conductive and dense targets, improved confidence in the interpreted magmatic conduit system, and provided a stronger technical basis for drill targeting.
A frequency-domain electromagnetic survey is expected to start shortly, which the company said would further refine the conductive responses and support final drill target prioritisation.
The Zeb Nickel Project is located on the northern limb of the Bushveld Complex, adjacent to Ivanplats' Platreef Project, which URU said is expected to become one of the world's largest underground platinum group metal operations once fully operational.
"We are very excited about the progress being made and the momentum building at the Zeb Nickel Project," Zorbas said.
"We look forward to the coming weeks and months and will continue to update shareholders regularly as results become available."
At 1242 BST, shares in Uru Metals were up 3.81% at 6.13p.
