Moho Resources hydrogeochemistry identifies anomalous gold zone of +90 kilometres at Empress Springs

Moho Resources Ltd's (ASX:MOH) regional hydrogeochemistry borehole sampling program at the Empress Springs Project in North Queensland has identified an anomalous gold zone stretching for at least 90 kilometres. The study with CSIRO was initiated in mid-2020 and was designed to use water samples collected from water bores to locate potential chemical signatures evidencing large mineralised systems hidden beneath the cover rock sequences.  Results demonstrate significant gold anomalism that highlights a +90-kilometre-long NW-SE trend that not only identifies previously discovered gold-base metal mineralisation, but highlights several new areas associated with complex crustal-scale structures that have the potential to host intrusion-related mineral systems. “Reinforces potential for new discoveries” The results will be used to orient and focus exploration towards finding new mineralisation in the Empress Springs project area.  Moho managing director Shane Sadleir said: “The identification of such a large hydrogeochemical gold anomaly at Empress Springs is a very exciting development for Moho.  “We are delighted with the results of this unique survey which has been conducted in conjunction with highly reputable researchers at CSIRO and overviewed by experienced explorer and Moho’s JV partner, IGO Ltd (ASX:IGO). “The study confirms the mineralisation discovered under cover thus far by Moho and significantly reinforces the potential for new discoveries within our granted tenements and surrounding areas which the company has recently applied for.” CSIRO data synthesis  The CSIRO compared the Moho results with two existing hydrogeochemical data sets, that of Giblin (CSIRO) and the Queensland Government publicly available data.  This geochemical analysis showed a highly anomalous tin, tungsten, molybdenum ‘porphyry’ intrusive signature and highlighted broad and high-level gold anomalism across the Empress Springs project which CSIRO has not seen elsewhere in this high concentration range and with these groundwater conditions. CSIRO senior principal research scientist Dr Ryan Noble said: “The region has a very broad and large gold signature in groundwater that has not been observed elsewhere in Queensland”  Anomalism matches previous interpretation The strong NW-SE trend of anomalism matches the major trans crustal structure previously interpreted by geologist Dr Jon Hronsky who said: “I believe Empress Springs could be a significant new gold-base metal province. "I think the hydrogeochemical gold anomaly is particularly impressive in terms of its strong contrast to background.” Location of water bores sampled by Moho in conjunction with CSIRO at Empress Springs. Croydon Gold Index Notably, expert analysis by IGO geochemist Dr Justin Drummond has also outlined several important findings, including the Croydon Gold Index calculation.  The gold indices highlight gold anomalism around the inferred ‘caldera’ in both the Moho and Giblin datasets, as well as a strong gold anomaly in bores to the southeast of the currently granted Moho tenement package. Consultant geochemist Richard Carver also analysed the data and agreed that gold anomalism at a regional scale is impressive and the area of lower pH in the project area could be due to weathering of sulphides. He also notes the W-Mo anomaly close to the interpreted caldera which also hosts a Sn-Cu-Pb anomaly associated with the only Moho samples with values above the detection limit. Seeking additional ground The company is very encouraged by the evaluation by CSIRO, IGO and Richard Carver of these geochemical results. As a result, Moho has applied for an additional 1018 square kilometres of EPM area to cover these hydrogeochemical anomalies, which will increase its landholding by 29% to 3,403 square kilometres.
