IMC Exploration Group plc Confirms Records of Gold in Historical Sampling

Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive

Analytical results received from IMCs 2019 exploration programme in the Goldmines River licence in County Wicklow (PL 3857) have reinforced gold values obtained in historical sampling.  Analyses have confirmed gold with values ranging up to 0.4 g/t Au in a selection of samples from prospecting and drilling.


IMC has compiled existing information from PL 3857 to focus exploration for bedrock gold mineralisation in the Goldmines River area.  Historical records indicate bedrock results of up to 2.8 g/t Au.

Earlier this year IMC prospected in the vicinity of former mine workings in the south of the licence area and encountered gossanous quartz vein material assaying up to 0.4 g/t Au with levels of associated elements leading to an inference that the mineralisation could be related to igneous intrusions.

Follow-up drilling encountered trace levels of gold contained in wall rock associated with the old workings.  This is potentially significant as, in one drill hole intersection, the wall rock is a highly sheared siliceous tuff containing 10% magnetite over a 6m interval and implies that fluids associated with gold mineralisation may have been widespread.

Furthermore, a moderately sorted, ‘washed-in’, coarse-grained sand was intersected in the old workings.  Analyses of the sand contained elevated levels of silver (up to 12.1 g/t Ag), tungsten (0.4% W) and nickel.  These elemental associations raise the possibility that the ‘washed-in’ sand is ‘sampling’ a range of mineralisation within PL 3857 and may be reflecting a multi-element mineralising system. 

Regional mapping has identified extensive zones of propylitic alteration as well as chlorite sericite alteration.  This alteration is supported by the presence of gold mineralised float. Chairman Eamon O’Brien commented ‘We are delighted to report records of gold in one of our historical samples in our Goldmines River Licence area.  These positive results bode well for our imminent sample testing on this licence area.  The results further justify the extensive drilling programme just completed and the ongoing works’ programme underway, which includes analysis of the drill results. These findings are in addition to our flagship spoils and tailings project in Avoca Co. Wicklow, where a JORC Code (2012) Mineral Resource Estimate has been completed.’
