Unicorn Mineral Resources Plc announced the results of the exploration drilling programme conducted in the summer of 2023 on its project "Kilmallock ", in the "Limerick Basin" in Ireland and situated 20km south of Glencore's "Pallas Green Lead and Zinc" prospect. Highlights: The exploration drilling programme consisted of seven holes for a total of 1,532.7m of coring,designed to extend the mineralised body, assess ground conditions, and define the geological /structural setting; This phase of drilling has confirmed the presence of prospective basal Waulsortian Reef hosted, Pallas Green style, Black Matrix (BMB) /Polymictic (PMB) breccias that are mineralised with low to medium grade zinc lead sulphides and oxides, UMK-004 intersected 2.8m grading 4.25% Zn /0.47% Pb /3.6g/t Ag; The drilling at the Bulgaden Target UMK-003 => 008 confirmed that the region is structurally complex with NNW striking, enechelon, ramp-relay normal faults with a throw of between 60 - 80m to the east. It also established that oxidation of the basal Waulsortian Reef and the breccia hosted sulphide mineralisation is developing from the north and is more extensive than previously thought; Drilling at the shallow Ballycullane deposit (UMK-002A) was affected by recovery issues in a technically challenging drilling environment.

However, material recovered (including sludge samples) contained unexpectedly high grade Silver assay results, 8.0m at a grade of 59.69g/t Ag, with a peak value of 85g/t Ag; Previous drilling on the Kilmallock Property has intersected significant, high-grade zinc, lead, and silver mineralisation at a number of zones, including one 3.8m intercept with 14.66% zinc, 4.8% lead and 133.79 g/t silver at a depth of 325m, leading Unicorn continues to believe that a major, undiscovered, mineralising system is located in this region. The region to the south and southeast is relatively untested by historic drilling and remains highly prospective. In addition, recent drilling by another operator on the Ballywire prospect 10km to the east of Kilmallock has produced some excellent results which are highly encouraging for the southern part of the Limerick Basin.
