Conroy Gold and Natural Resources plc has discovered antimony-bearing float samples from its Clontibret gold deposit area in County Monaghan, Ireland.
TREND
The company said it identified the boulders during recent work near a reported historic antimony trial pit, northeast of the two historic antimony mines of Tullybuck and Lisglassan.
The company noted that the Clontibret area was known for its small-scale antimony mine operations active during the 18th and 19th centuries.
Historical references exist of a trial pit associated with the area where the float boulders were recovered.
Samples returned gold grades of 21.9 g/t and 11.2 g/t gold while results for antimony were above detection limits greater than 1% (10,000 parts per billion).
Portable X-ray fluorescence (pXRF) analysis returned “indicative results in excess of 40% antimony” and detailed assays are pending of antimony ore grade content.
The work is part of Conroy’s aim to demonstrate the antimony potential of Clontibret and evaluate the second antimony trend identified in February.
Relogging of drill core from the deposit also continues as well as construction of a more robust 3D geological model and follow-up antimony exploration.
