The Thurles Licence Block was recently awarded to Connemara and consists of three contiguous prospecting licences, covering an area of approximately 101.47km2 of County Tipperary.. The block is located approximately 5km south of the Lisheen Mine - a Waulsortian Reef hosted deposit (22.79Mt, 12.04% zinc / 2.05% lead) and 12km southwest of the Galmoy Mine, also hosted by the Waulsortian Reef (9.9Mt, 12.8% zinc / 1.3% lead).
The block is located along the southern edge of the Rathdowney Trend regional basement lineament and is primarily underlain by shelf limestone facies with the Waulsortian Reef outcropping in an inlier to the northeast. Within this inlier the contact between the base of the Waulsortian Reef and the ABL is exposed. The Waulsortian of this part of the Irish Midlands is regionally dolomitised. Immediately to the north of the block, close to the town of Thurles, historic drilling by Cominco intersected a very well developed Iron formation at the base of Waulsortian Reef, it is postulated that this is a distal, up dip indication of mineralisation.
