Connemara Mining Company plc are very pleased to to announce drilling results from the Stonepark Zinc Project. The RNS can be viewed HERE.
- G11-2638-01 intersected 5.40m of 25.0% zinc and 7.2% lead (32.2% Zn+Pb combined) and 12.2 g/t silver (true width is estimated at 4.9m), verifying one of the high-grade zones within the Stonepark Resource;
- Robust mineralisation interpreted to be open eastwards toward Glencore’s neighbouring Pallas Green deposit.
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, where Glencore have established a JORC-compliant resource of 44.2 million tonnes of 7.2% Zn+ 1.2% Pb in the Inferred Category (Glencore; 31 December 2017). The Joint Venture was originally formed with Teck of Canada who earned in 76.56%, drilling 54,767 metres between 2007 and 1012 and conducting other geological and geophysical studies, including 18 line kilometres of seismic surveying. Connemara holds a 23.44% working interest. Teck sold their share to Group Eleven Resources Corp. in late 2017. 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 drilling recommenced in March 2018.
Connemara’s RNS news release dated April 17, 2018 relied on CSA Global’s original Mineral Resource Estimate of 5.3Mt @ 8.55% Zn + 2.60% Pb (11.15% combined). This estimate has since been updated to 5.1mt @ 8.7% Zn+ 2.6% Pb (11.3% combined), reflecting an adjustment to the calculation of cut-off grade. In the opinion of CSA Global, the adjustment did not make a material difference to figures quoted. Note that contained metal before and after the adjustment remains at 1.3 billion lbs Zn+Pb, as summarised in the table below:

A copy of the Independent NI 43-101 Technical Report submitted to SEDAR by Group Eleven Resources Corp. is available HERE (8 Mb). 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.
