Adventus Mining Corporation announced the commencement of exploration scout hole drilling on its Rathkeale block in County Limerick in the Republic of Ireland. The work is being done under the earn-in agreement with a wholly owned subsidiary of South32 Limited ("South32"). These three project areas encompass 1,277 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 operator during the earn-in period. The Rathkeale Block consists of a total of eight contiguous prospecting licences covering an area of approximately 255 km of prospective ground for base of Waulsortian Zn-Pb mineralization in west County Limerick. The block lies immediately west of Glencore's Tobermalug deposit (45.4 Mt inferred mineral resources grading 7% zinc and 1% lead), and Group Eleven's Pallas Green West and Stonepark projects. The rocks underlying the Rathkeale Block are primarily Lower Carboniferous in age. The geological history of the area progressively records the early Carboniferous marine transgression across the Old Red Sandstone continent, development of Vis?an basin and shelf palaeoenvironments and later deposition of the late Namurian strata of the Newcastle West area. Historical drilling and geological interpretation suggest that the Rathkeale syncline is a complex of half graben structures associated with a series of ENE trending, Early Carboniferous extensional faults. Thick breccias and conglomerates along with associated alteration including dolomitization and black matrix breccia have been intersected in historical drilling on this zone. This polymict sequence of Rathkeale Limestone and Waulsortian Mudbank clasts indicates large scale faulting following the initial deposition of the Waulsortian. Regional extension was accompanied by gravitational collapse and excavation of footwall scarps during Chadian to Arundian; a similar age to that recognized in the north Dublin Basin and more significantly coeval with development of the Boulder Conglomerate at Navan. Over the last year, the target generation compilation was updated to include all the new exploration data being collected over the Rathkeale Block. Large datasets for surficial geochemistry (including soil and lithogeochemical samples), historical drilling, historical geophysical studies (gravity, magnetics, electromagnetic) and geological mapping were incorporated and developed into working models. Each target that was developed required rock exposures to be checked and mapped; however, high-priority areas had a combination of geochemical & geophysical techniques were applied (ionic leach soils, SGH, ground MT) to further enhance target refinement for drilling. To visualize the Rathkeale geological and structural framework, detailed cross-sections using historical drill hole and recent seismic information were constructed and digitized. These cross-sections were then added to a Leapfrog Geo 3D model that was developed for visualization of all target generation initiative ("TGI") datasets. This 3D model allows for enhanced target selection in the 3D environment, notably for drill hole planning. A key component of the Phase 1 scout hole drilling at Rathkeale is the refinement and verification of the current geological and structural interpretation, which will lead to the overall enhancement of target evaluation. The seven Phase 1 scout hole drill targets were selected due to a combination of pre-existing targeting utilising 2017 seismic data, updated structural-stratigraphic targeting, historical mineral occurrences without base of Waulsortian test current geochemical-geophysical targeting. The first drill hole in the program, collared in late November 2021 is drilling on the Killeen target in licence PLA 3368. The Killeen target is in the hanging wall of the GB fault, close to an original 2018 seismic target (Attyflin). This scout hole is aimed at targeting at an area of anomalous LGC (hydrothermal pyrite & barite signature), a conductive feature identified in the ground MT survey in the HW of a key structure on the block and at providing essential geological context. The siting of the hole, 1.5 km from the seismic line ADV17-01 will allow the collection of downhole velocity data which is the next key step in the interpretation of seismic data. Additionally, the hole will act as a test of the use of the MT method as a subsurface interpretation tool in this environment. Two holes 21-3609-01 and 21-3732-01 were completed in mid-2021 on the Marl Hill (Julianstown) and Marvelstown targets respectively described in the May 6, 2021, news release. Although only trace levels of zinc-lead mineralization were intersected in each drill hole, the key target horizon, known as the Pale Beds, was present and well developed, which confirmed modeling. The presence of slumped sedimentary breccias at Mark Hill in drill hole 21-3609-01 further enhances the prospectiveness of the target area. The pXRF data collected on drill core indicates elevated base metal concentrations in the Micrite Unit that appears to be the most prospective assemblage intersected in 21-3732-01. The pXRF data also indicates a greater degree of hydrothermal alteration in this part of the basin denoted by hydrothermal dolomite signatures (with enrichments in manganese, iron, and magnesium). The profiles of the Pale Beds in 21-3732-01 show a broad pattern of mineralization and alteration, with a galena dominant signature towards the base of the Pale Beds and sphalerite mineralization at a higher elevation. Both weakly mineralized zones are interpreted as fault-controlled mineralization with the lower zone being more sulphide deficient (lead and barium enriched), whereas the higher zone having formed in a more reduced environment leading to low arsenic pyrite, low cadmium sphalerite, more sphalerite formation relative to galena with associated dolomitization. With these two drill holes, only a very small portion of the prospective area from the Kingscourt Fault east along the broad hanging wall of the Ardee Moynalty Fault Zone has been tested. This area is thought to be a compartmentalized basin that has a large area of untested prospective ground yet to be drilled. A key area of interest is the Marvelstown to the Kingscourt Fault area where pXRF data indicates a greater degree of hydrothermal activity. The use of innovate processing of pXRF data to model stratigraphy has confirmed the absence of an approximate 60 m section of the ABL in 21-3609-01, which is observed both in drill core and in chemical profiles.
