Unicorn Mineral Resources (LSE:UMR), an LSE-listed explorer targeting zinc, lead, copper and silver in Ireland, has published results from 3D gravity modelling at its Kilmallock project in County Limerick, identifying five pronounced density anomalies that have not been tested by historic drilling.
The anomalies are associated with northwest-southeast fault structures considered prospective for massive sulphide mineralisation, the same geological setting that guides exploration at Group Eleven Resources' Ballywire deposit, located approximately 8 kilometres along strike to the east.
One elongated anomaly south of Bulgaden, where a previous drillhole intersected 4.5 metres grading 16.53% zinc and 1.25% lead, appears fault-controlled and remains untested, suggesting the known mineralisation could be a satellite of a larger system.
The geophysicist's recommendation was to extend the gravity survey eastward toward Ballywire and southward across the Supra-Waulsortian zone before any targeted drilling programme is designed.
Unicorn has engaged BRG Geotechnics to carry out a 340-station survey, increasing data density to approximately one station per 200 metres across the most prospective areas, with fieldwork having commenced in June.
"Further survey work needs to be carried out at Kilmallock before we commit to drilling expenditure," said Chairman Paddy Doherty, "but it is greatly encouraging that both our Kilmallock and Lisheen properties are located in areas that are the focus for the latest phase of discovery and development."
