Zinc of Ireland NL reports that its maiden drilling campaign at Rapla, which was won by way of a successful ballot application, started on 29 April 2022. A total of 14 holes were successfully permitted by the company. The immediate high priority drilling will consist of 3 holes into a walk-up drill target that appears very similar to the famous, and neighbouring, Lisheen Mine 10km away in terms of target area, geology and feeder fault model.

Rapla is a typical "Irish Type" (e.g. Lisheen & Galmoy) target, where the company expects the potential for higher-grade mineralisation of greater thickness to increase approaching the feeder structure/fault. At Rapla, the closest historical drill hole, which is located 600m away from the potential feeder fault hit high grade mineralisation. All other proximal holes contained sulphide mineralisation, which the Company has evaluated as an exceptional precursor to successfully targeting an economic accumulation of sulphides in proximity to the potential feeder.

The company notes that the Lisheen main zone orebody was approximately 600m long and 1,200m wide before being mined out, which is similar in length to the target zone at Rapla being drilled. Drill core from the initial three holes will be processed and sent for analysis immediately after drilling.
