Adventus Mining Corporation announced the commencement of exploration drilling on its Kingscourt block in the Moynalty Basin in the Republic of Ireland. The work is being done under the earn-in agreement with a wholly owned subsidiary of South32 Limited, which has a right to acquire a 70% interest in the Kingscourt, Rathkeale and Fermoy blocks, which are 100% owned by Adventus through its wholly owned subsidiary, Adventus Zinc Ireland Limited. These three project areas encompass 1,155 km2 of favourable strata known to host Irish-type zinc-lead-silver systems. South32 is required to fund EUR 3,500,000 in exploration on the three blocks over a four-year period with AZIL acting as opera tor during the earn-in period. The Kingscourt block is composed of thirteen prospecting licenses covering 422 km2 of prospective lands for Irish-type zinc-lead-silver systems hosted in the Lower Carboniferous shallow water carbonate rocks. The project is located 10 km north of the large Navan zinc-lead-silver Mine (also known as the Tara Mine), discovered in 1970 with production having started in 1977. By the end of 2013, the Navan Mine had seen total production amounting to 83.2Mt grading 7.9% zinc and 1.9% lead. The Kingscourt Outlier is understood as an extension to the Dublin Basin, which hosts the Navan deposit, and is known as the Moynalty Basin. It is a northeast trending sub-basin predominantly containing the same favourable Lower Carboniferous platform carbonate rocks referred to as the Pale Beds, overlying a Lower Palaeozoic basement. A wedge of Permo-Triassic rocks forms the final infill of the half graben structure abutting the Kingscourt fault. The structural regime influencing mineralization at the Navan Mine includes an east-northeast trending and northwest dipping extensional relay fault system, a structural pattern also displayed in the Kingscourt block area.Mineralization at the Navan Mine is thought to be due to the mixing of metal-rich and sulphur-poor hydrothermal fluids leaching metals from the basement with sulphide-rich surface brines developed in small localized basinal areas in half grabens. Continuing tectonic extension is thought to have allowed the development of increased fracture permeability in host environment creating an ideal depositional environment that allowed the formation of Navan Min e. The structure of the region shows some later effects of overprinting by the Variscan Orogeny, particularly with inversion n on the principal extensional structures. 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, 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. 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 Navan Mine. At Marl Hill, the drill hole is targeting the hanging wall of both the Julianstown and Ardee-Moynalty faults just north of mapped slump and sedimentary breccia beds looking to intersect the base of the favourable Pale Beds. Along an 8 km strike length of the Ardee-Moynalty fault, only two thirds of historical drill holes completed by previous operators recorded having evaluated the full hanging wall of the fault, and therefore testing the Pale Beds target horizon.
