This is where the Clay lake nugget was found in 1980. The gold anomaly extends for 2 km by 1 km, (c.140 ha / 350 acres). More than 80 soil samples were collected over the anomaly giving gold-in-soil values averaging over 50 ppb, with six samples between 100 ppb and 1,531 ppb (1.53g/t). The surface area of the discovery is greater than that of Clontibret (c.125 ha / 310 acres) and the gold-in-soil concentrations are double the average of those recorded at Clontibret.
The Clay Lake target has three main areas of mineralisation: Clay Lake, Cargalisgorran and Tivnacree. The latter two smaller areas within the target area to the west were identified early in the 2000s by soil geochemical prospecting. Over one part of this anomaly, at Cargalisgorran and Tivnacree, bedrock comes close to surface and subsequent trenching showed elevated gold values.
Following soil sampling, geological mapping and interpretation, drill targets were identified at Cargalisgorran. The first two drill holes intersected the extension of zones identified in the trenches and returned mineralised intercepts of 6.94m grading 4.14g/t gold and 9.27m grading 1.88g/t gold. The two original discovery holes have now been supplemented by a further seventeen holes drilled to an average down-hole depth of 76m. Follow up drilling has extended the zone of mineralisation to over 150m along strike.
Tivnacree was identified early in the 2000s by soil geochemical prospecting which outlined an extensive gold anomaly and has been followed up by subsequent trenching showing elevated gold values. Two drill holes have been drilled to date in this area.
