The Derrykearn Project consist of six licences in total, five contiguous licences in County Laois and a single licence to the south of Rapla (PL3313). The licences lie along the Rathdowney Trend, to the east of Galmoy, mined by Lundin and north-east of Lisheen Mine, mined by Vedanta.
Connemara has commissioned compilation of historic data over the licences. The geophysical data includes electromagnetic induction and induced polarisation surveys. The geochemical data from soils and deep overburden sampling includes over 900 data points with a full suite of geochemical assays, plus another 5100 plus Zn-Pb-Cu assays from older generations of surveys. The lithological and sampling data from more than 80 holes representing a total meterage of over 9,000 metres of diamond drilling is being reappraised with a view to generating new targets. Of particular interest is the lowest non-argillaceous carbonate unit in the stratigraphy,the Lisduff Oolite, at Derrykearn and remains untested by diamond drilling. At Lisheen, resource-grade mineralization was hosted within the Lisduff Oolite.
Geology of the Derrykearn area and previous drilling testing base of Waulsortian (five contiguous Connemara licence areas in red outline). One further licence to the south, 3 km east of Galmoy mine, PL3313, is included in thie Derrykearn project.
