Our exploration licence in the Limerick Basin is highly prospective for zinc, lead and silver and is only 10 km away from and part of the same target unit as the Pallas Green zinc discovery.  

Alba's most recent work on prospecting licence PL3824 has consisted in late 2016 of a gravity and soil survey to help better understand the structural elements of the licence area that may be controlling the known sulphide mineralisation that is present within the licence boundaries.  Interpretation of the gravity data suggests the presence of gravity anomalies consistent with brecciation of the host limestone, with zinc and lead anomalism in shallow soil samples collected above or adjacent to gravity anomalies.  Eleven samples from pXRF considered to be highly anomalous (131 to 269 ppm Zn) for zinc, and 12 samples anomalous for lead (38-93 ppm Pb).  The brecciation identified by the gravity survey is a feature that is associated with Irish-Type mineralization, whereas the portable XRF data suggests the licence is located in an area of base metal anomalism.  The results of soil geochemistry assays are awaited (January 2017).

Prior to this most recent work, Alba conducted geological mapping, shallow soil geochemistry, lithogeochemistry, VLF geophysics and drilling. Alba's joint venture partner from 2010 to 2014, Teck Ireland, undertook a microgravity study on the central part of the licence, and completed four diamond drillholes.

The four diamond drill holes (totalling 956.7 m) were drilled in 2012.  The holes were drilled to test the stratigraphy of the licence and the mineral potential within Lower Carboniferous limestone close to younger mafic lavas and intrusions (as present at the Stonepark project 9 kilometres to the north).  Drillhole TC-3841-3 intercepted 6 metres of semi-massive and disseminated pyrite between 508 and 514 metres within the target limestone.  A 2 metre mineralised interval within the aforementioned interval contained 0.58% Zn, and trace amounts of lead (208 ppm). The presence of pyrite is encouraging since it often indicates the presence of base metal sulphides at other properties in the Limerick basin.
