18 Jan Further Drilling Extends Shinganda Project
(“Galileo” or “the Company”)
· Nine angled diamond drill holes completed at the Shinganda outcrop prospect totalling 1,227.2m confirm a supergene copper-gold mineralised gossan zone containing malachite, chalcocite, native copper and associated gold mineralisation
· Among the assay intersections recorded were:
· 50.3m @ 1.54% Cu, 0.30g/t Au from 21.0m in hole SHDD002
o Including 7.0m @ 4.36% Cu, 1.51g/t Au from 47.0m
· 43.7m @ 1.01% Cu, 0.18g/t Au from 7.3m in hole SHDD004
· 11.0m @ 1.03% Cu, 0.55g/t Au from 102.0m in hole SHDD005
o Including 3.4m @ 2.89% Cu, 1.61g/t Au from 102.0m
· 16.0m @ 0.72% Cu, 0.04g/t Au from 11.0m in hole SHDD006
· The zone as defined so far extends for about 200m x 100m in plan, and to about 70-80m vertical depth, with a higher-grade core and lower grade margins
· Drilling towards the west-northwest and the east shows that mineralisation is not closed off in these directions
· Strong hydrothermal alteration and brecciation is suggestive of a significant hydrothermal and supergene system at Shinganda, possibly controlled by regional and local faulting
· Primary chalcopyrite copper mineralisation encountered deeper in hole SHDD005 may represent the original sulphide source of the remobilised supergene mineralisation.
· 3D modelling of the deposit is proposed to assist in planning additional drilling, while further evaluation is continuing on other prospects within the exploration licence showing similar characteristics
Colin Bird Chairman & CEO said: “The Shinganda prospect is demonstrating significant potential as a copper-gold exploration project, with very encouraging intersection widths from drilling to date. We are continuing to carry out pitting and trenching on additional nearby targets to demonstrate further potential within the licence area as we pursue our aim of drill testing several of these targets during the first half of 2023. Results to date show that the area is highly prospective, and we look forward to carrying out and reporting on the next phase of work.”
Drilling Results to Date
Galileo interest in the Shinganda area initially focussed on a historic angled drill hole completed in 1959, which reportedly cut a near-vertical zone of heavily veined sediments and copper oxides.
Nine follow-up diamond drill holes were completed by the Company in Q3 and Q4 2022 at the Shinganda outcrop prospect totalling 1,227.2m. All holes passed through a stratigraphic package comprising mainly siltstone, dolomite and argillite of the Neoproterozoic metasedimentary suite of the Kundelungu Group. Copper and gold assay results have now been received for all nine holes – see Table 1 below for a summary of the main intersections of interest.

Galileo’s drilling has confirmed and extended the Shinganda hematite breccia gossan zone copper-gold occurrence, containing supergene malachite, chalcocite and native copper mineralisation. The core zone on the main profile drilled is about 35m wide and extends from surface to at least 70m vertical depth. The overall mineralised zone covers an area of about 200m x 100m in plan and it has not yet been closed off in several directions, particularly to the east, the west-northwest.
A 25cm interval of semi-massive native copper was noted at approximately 103m downhole depth in hole SHDD005 within the hematite zone. Chalcopyrite mineralisation also occurs deeper in hole SHDD005 in bands and associated with quartz-carbonate veining around 133m-143m downhole depth, which may represent the original sulphide source of the remobilised supergene mineralisation.
Strong bedrock alteration and brecciation, including quartz-carbonate, silica and potassic alteration types are seen flooding through intervals of core in several holes, particularly SHDD003, SHDD005 and SHDD006, suggestive of a significant hydrothermal and supergene system at Shinganda.
3D modelling of the deposit is now proposed to assist in planning additional drilling, while further evaluation is continuing on other prospects within the exploration licence showing similar characteristics.
