Galileo Mining Ltd (ASX: GAL) has confirmed the potential of the Delta Blues DB2 target with positive assay results from three reverse circulation (RC) drill holes recently completed within the Fraser Range Belt in Western Australia.
All three drill holes targeted the very top of a large electro-magnetic (EM) conductor and all three holes recorded sulphide intercepts with anomalous amounts of copper and gold. Diamond drill core testing is now required to test for economic mineralisation beneath the currently reported intercepts at DB2 and to determine the source of the strong EM conductor at the DB1 target.
“The assay results from the first round of drilling at our Delta Blues prospect are very encouraging with anomalous copper-gold sulphides in all three drill holes at the DB2 target,” Managing Director, Brad Underwood, said.
“Given we have only drilled the very top of the large EM conductor at DB2 and have yet to identify the source of the conductor at DB1, there is significant potential for success at the Delta Blues prospect and within our Fraser Range tenements more generally.
“Follow up diamond drilling will be undertaken at Delta Blues after we have completed additional down hole and surface EM surveys. This will enable us to target the best parts of the conductors and maximise our chances of a successful outcome.”
Copper-gold assay results included:
- 4 metres @ 0.29 g/t gold and 0.29% copper from 188m(DBRC001) including;
- 1 metre @ 0.61 g/t gold and 0.66% copper from 190m
- 5 metres @ 0.10 g/t gold and 0.25% copper from 167m (DBRC002)
- 4 metres @ 0.21 g/t gold and 0.27% copper from 154m (DBRC003)
Geology logging at DB2 recorded a thin layer of sediment cover overlying typical Fraser Range meta- sediments and mafic granulites near surface. Small units of mafic (gabbro) intrusive rocks within the meta- sediments were noted prior to the sulphide zones.
The sulphide mineralisation in all drill holes occurs as semi- massive bands surrounded by disseminated sulphide within a mafic intrusion adjacent to a medium grained felsic intrusion. These intrusions have been preliminarily logged on site as a gabbro and a tonalite with petrography underway to determine the precise rock classifications.
One metre split samples from RC drillholes DBRC001, DBRC002, and DBRC003 were sent to the laboratory for priority analyses. These samples were collected between 179m and 200m (DBRC001), 160m and 180m (DBRC002) and 146m and 186m (DBRC003).
Mr Underwood said the economic implications of the assay results from DB2 are at this stage uncertain with deeper diamond drilling required to test the better parts of the EM conductor at depth. The scale of the modelled EM conductor at Delta Blues DB2 is substantial with dimensions up to 500m by 500m.
The initial three drill holes completed at DB2 have confirmed sulphide mineralisation over a minimum strike length of 210m. Only the very top of the conductor has been drilled and down hole EM surveying will be undertaken to refine the targets prior to diamond drill testing.
Timing of diamond drilling is subject to rig availability as Western Australia continues to be affected by labour shortages which limit the ability of contractors to undertake Galileo’s drill programmes.
