Northwest Leinster Project Work Update:
The NW Leinster Project is focused on the exploration for lithium mineralization (spodumene pegmatites) in the north of the Leinster Massif in south-east Ireland. The project area is covered by fifteen (15) prospecting licences termed the North-west Leinster Block which covers a total area of 477.39 km2. The prospecting licences were granted to LRH Resources Limited in October 2018 and are valid for an initial period of six-years from that date.
The NW Leinster project is located at the north-east end of the East Carlow Deformation Zone (ECDZ) with licences also located to the north of this zone in interpreted similar structural settings. To the immediate south-east, a 55km long zone of discrete lithium-bearing pegmatites & aplites, centred on the Aclare deposit was discovered during 1960s and 1970s near the contact of the Tullow Lowlands granite pluton with the Lower Palaeozoic metasediments which are considered genetically as well as spatially related to the ECDZ. The Aclare deposit (part of International Lithium Corp – Ganfeng Lithium Co. Ltd JV’s Avalonia Project) which reportedly comprises a 20m wide spodumene pegmatite zone with a non-compliant historical resource estimate of 570,00 tonnes grading 1.5% Li20; strike length of primary target zone is approx. 550m with best intersections of 2.23% Li20 over 23.3m including 3.43% Li20 over 6m.

The planned exploration programmes over the NW Leinster Project during the period have successfully located new, and previously unknown lithium pegmatite mineralization on the block in areas initially targeted using legacy Geological Survey geochemical data and followed up with detailed field surveys. These areas are:
- Aghavannagh Prospect – large angular blocks of spodumene pegmatite (float) returned the maximum value of 8280ppm Li (1.78% Li2O) in sample AES43343 on PL4541.
- Sorrel Prospect - pegmatite float with 3cm-5cm prismatic spodumene crystals in sample AES34326 on PL4536 returned a value of 7680ppm Li (1.65% Li2O).
- Tonygarrow Prospect - spodumene pegmatite located (0.99% Li2O).
- Scurlocks Prospect – aplite float with anomalous lithium (0.65% Li2O).
- Knocknaboley Prospect - anomalous lithium (820ppm Li) in aplite float on PL4546
The spodumene bearing float discovered at the Aghavannagh was further investigated by detailed mapping, prospecting, deep overburden geochemical surveys and a 12.5-line kilometre ground magnetic survey. The area represents the first emerging drilling target at Aghavannagh on PL 4541 where exploration focus will continue into the next period of tenure while the other prospect areas are similarly explored using the successful exploration strategy developed at Aghavannagh.
The NW Leinster Project has extended known mineralization along the full length of the East Carlow Deformation Zone a full 75km from SW to NE through the identification on the NW Leinster Projects block of licences. Occurrences of spodumene pegmatite float at discrete locations throughout the block, indicate the potential for close to surface ore grade mineralization like that seen at the Avalonia projects Aclare and Moylisha targets.
The NW Leinster projects significant exploration results are considered highly encouraging, and further exploration programmes are currently being planned across the block with an immediate priority on identifying a drill target at the Aghavannagh Prospect.
