New Porphyry Copper System Discovered on the Bushranger Project
The Board of Xtract Resources Plc (“Xtract” or the “Company”) is very pleased to report the discovery of a new copper mineralised porphyry system on the Bushranger copper-gold exploration project. The discovery has been made by drilling an Induced Polarisation (“IP”) geophysical anomaly undertaken as part of the ongoing Phase 2 diamond drilling programme.
· Two drill holes have intersected a new copper mineralised porphyry system associated with an IP geophysical anomaly generated by the Company during the period between the Phase 1 and Phase 2 drilling programmes
· The new discovery, located 1.5km to the south-east of the boundary of the Racecourse Inferred Mineral Resource, has been named the “Ascot” prospect, with follow-up drilling already under way
· Based on preliminary logging, hole BRDD-21-033, which was angled to the east, intersected a long interval of alteration and sulphides. Traces of copper mineralisation extended from a down hole depth of 85m until the end of hole at 783.7m, a total interval of 698.7m. This included a zone of stronger visible chalcopyrite and pyrrhotite mineralisation over a 110m interval from 670m downhole depth.
· Follow-up hole BRDD-21-035, drilled from the same pad towards the west, confirmed the new discovery. Preliminary logging recorded traces of copper mineralisation from 60m downhole to the end of hole at 740.3m, with two zones of stronger visible copper mineralisation over intervals of 113m from 179.4m depth and 128m from 554m depth
· Laboratory assays will be required to determine the intervals of potentially economic grade for BRDD-21-033 and BRDD-21-035
· The mineralisation intersected in these two holes explains the IP anomaly in the area of the Ascot discovery, and further drilling is planned to test the larger cluster of anomalous IP signatures in the south-eastern area of the Bushranger prospect (Refer RNS 13 October 21)
Colin Bird, Executive Chairman said: “This is an exciting new discovery, and the team should be complimented for making such a discovery in an established geological setting. Based on preliminary logging and subject to laboratory assays, holes BRDD-21-033 and 035 represent two very meaningful intersections, similar to the main Racecourse deposit. The intention now is to test for up-dip mineralisation and to establish strike direction with a view to building up a further mineral resource at Ascot. We have also commenced a new hole to test another geophysical anomaly separate from Racecourse and Ascot.”
Bushranger Phase Two Drilling Update – Drill Hole BRDD-21-033
Drill hole BRDD-21-033 was drilled at an inclination of -70 degrees towards to the east and was completed at a final depth of 783.7m. The hole is situated 1.5km to the south-east of the main Racecourse Inferred Mineral Resource and is the first hole drilled into the south-eastern IP anomaly. The hole intersected extensive porphyry-type alteration and iron sulphides, with traces of chalcopyrite mineralisation at 85m down hole depth until the end of hole, a total interval of 698.7m, which included a stronger intersection of chalcopyrite and pyrrhotite mineralisation over a 110m interval from 670m downhole. This new discovery to the south-east of the Racecourse porphyry has been called the “Ascot” prospect.
Drill hole BRDD-21-035 was the first hole drilled to follow up the new Ascot discovery and was drilled towards the west at an inclination of -60 degrees from the same drill pad as the discovery hole. Preliminary logging recorded traces of copper mineralisation from 60m downhole to the end of hole at 740.3m, with two zones of stronger visible copper mineralisation over intervals of 113m from 179.4-292m depth and 128m from 554-612m depth.
The mineralisation and wide intervals of alteration intersected in these two holes at the Ascot prospect display very similar characteristics to that observed at the Racecourse Inferred Mineral Resource and the company intends to model the structural information available in these holes to define the potential strike continuity of the Ascot prospect in follow-up drilling. Laboratory assays will be required to determine the intervals of potentially economic grade for BRDD-21-033 and BRDD-21-035
The Ascot IP anomaly forms part of a larger cluster of anomalous IP signatures in the south-eastern area of the Bushranger prospect and further drill holes are planned to test these anomalies as part of the Phase 2 diamond drilling campaign (Refer RNS 13 October 21).
