Highlights:
- Seven new high priority targets were developed at Kingscourt block using a multi-disciplinary approach over the last year incorporated into a detailed target generation initiative ("TGI")
- A total of 4,500 metres of drilling has been planned for the Kingscourt block targeting Pale Bed-hosted Irish-type zinc-lead deposits starting with an initial two scout drill holes at the top-rated Marl Hill (Julianstown) and Marvelstown targets on the hanging wall of the Ardee-Moynalty fault
- Approximately 35% of historical drill holes reviewed for the Kingscourt block did not test the prospective Pale Beds target horizon
Kingscourt Block Geology
The Kingscourt block is composed of thirteen prospecting licenses covering 422 km2 of prospective lands for Irish-type zinc-lead-silver systems (Figure 1) hosted in the Lower Carboniferous shallow water carbonate rocks. The project is located 10 km north of the large

Target Generation Initiative
Over the last year, all available exploration datasets were compiled and reprocessed to merge with new data being collected from ongoing surface exploration over the Kingscourt block. Large datasets for surficial geochemistry (including soil and lithogeochemical samples), historical drilling (98 drill holes), historical geophysical studies (gravity, magnetics, electromagnetic, GeoTEM, and Radiometrics), and geological mapping were incorporated with new micropaleontological dating samples collected while verifying existing rock exposures and mapping new outcroppings identified over the last year of work. A detailed ionic leach sampling grid over priority target areas was also incorporated to help interpret the lithogeochemical model to facilitate changes to both the geological and the structural-stratigraphic model.
To visualize the Kingscourt geological and structural framework, detailed cross-sections using historical drill hole information were constructed across the 13 prospecting licenses of the Kingscourt block. These cross-sections were then added to a Leapfrog Geo 3D model that was developed for visualization of all TGI datasets. This model allowed for enhanced target selection in the 3D environment for drill hole planning purposes. A total of seven new targets were determined for the Kingscourt block from the TGI. These new targets were put into a ranking matrix assessing geological and structural frameworks, hydrothermal alteration, lithogeochemistry, soil geochemistry, presence of sulphide mineralization, geophysical responses, and the mineral potential to host an Irish-type zinc-lead-silver system.
Two scout drill holes were budgeted for second quarter 2021 with Marvelstown and Marl Hill (Julianstown) being the top-rated targets (Figure 3). The Marvelstown drill hole is targeting the hanging wall area of the Adree-Moynalty fault and the footwall of the Oristown fault where there is a moderate to strong copper anomaly, noting that copper tends to occur proximal to feeder structures of Irish-type systems like the
Next Steps
Additional drilling later in 2021 on the Kingscourt block is contingent on results from the two scout drill holes at Marvelstown and Marl Hill (Julianstown), however, five remaining targets are ready for evaluation. In the interim, work continues planning for a scout drill hole on the Rathkeale block on its highest rated target. Finalization of targeting is pending receipt of analytical results from detailed ionic leach soil sample grids that are to be incorporated into the Rathkeale TGI.
Technical Information and Quality Control & Quality Assurance ("QAQC")
Project work in
A QAQC program is also in place at ALS and includes insertion of blanks, standards, and duplicate reanalysis of selected samples. ALS' quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025: 1999. At ALS, elements are analyzed using a 48-element 4 acid digestion with ICP-MS technique with overlimit testing in place using ore grade methodologies, also with 4 acid digestion.
