The Stonepark Project comprises six contiguous prospecting licences in County Limerick, Ireland. The licence block is located in a highly prospective area for base metal mineralisation and is 5km from the Tobermalug and Caherconlish zinc discoveries at Pallas Green that are currently being evaluated by Glencore. The Joint Venture was originally formed with Teck of Canada who earned in 76.56% with an expenditure of some $9m, drilling over 54,000 metres between 2007 and 1012. Connemara holds a 23.44% working interest. Teck recently sold their share to Group Eleven Resources. Group Eleven is a Canadian-listed company with extensive base metal licence holdings in Ireland. MAG Silver Corp. and Teck Resources (both listed Canadian companies) hold 22.0% and 6.3% respectively of the equity on a fully diluted basis. Group Eleven listed on the TSX in late 2017 and work on the block will proceed shortly.
Prospective Waulsortian Reef Limestones lithologies underlie much of the block. These are overlain in part by Supra-reef Limestones and Volcanics.
The exploration programme has included: Airborne Gravity Survey, Seismic Reflection Survey, Regional Soil Geochemical Survey and Downhole IP. The drill programme has completed more than 135 drill holes.

Stonepark mineralization continues to be extended and remains open in all directions at Stonepark West. Regional drilling across the block continued to target combined geological/geochemical/geophysical targets with some success, for example:
- TC-2638-084 at Fedamore which intersected minor vein sphalerite and galena below 300m.
- TC-2927-007 at Rockfield with minor colloform sphalerite below 292m.
- TC-2927-008 at Crecora with thick zones BMBs, massive pyrite and minor sphalerite
- TC-450-009 at Limerick South with extensive dolomitization, minor vein sphalerite below 441m.
