The Board of Xtract Resources Plc (“Xtract” or the “Company”) is pleased to report progress on angled holes BRDD-21-013 and 014 of the Phase Two diamond drilling programme at the Bushranger copper-gold porphyry exploration project in New South Wales.
· Hole BRDD-21-014, sited to test a new IP geophysical target to the southeast of the Racecourse Indicated Mineral Resource, intersected a wide alteration zone with pyrrhotite/pyrite mineralisation and associated copper sulphides
· Preliminary data from a drone-mounted magnetic survey indicates that BRDD-21-014 may be located within the margin of a new segment of the Racecourse porphyry system, with detailed modelling of the survey results and drillhole data to direct further drilling on this target
· Hole BRDD-21-013, drilled at -50 degrees within the south-eastern part of the conceptual Racecourse open pit, was completed at 855.5m having intersected intervals of chalcopyrite mineralisation over about 305m length from 84m depth
· Logging and splitting of core from holes BRDD-21-007, 008 and 009 has now been completed and samples have been dispatched to the analytical laboratory, with work continuing on the remaining holes
· Processing/modelling of the drone-mounted magnetic survey at Racecourse will continue, with a focus on the new south-eastern target indicated by hole BRDD-21-014
Colin Bird, Executive Chairman said:
“These most recent holes help to confirm our prognosis for a large open pit in that hole BRDD-21-013 intersected the first copper mineralisation quite near surface, extending over a substantial interval of more than 300m.
BRDD-21-014 encountered a wide interval of sulphide mineralisation suggesting that the airborne geophysics programme has identified a new zone or possibly a sheared zone from the Racecourse deposit. Recently received magnetic survey results suggest that the hole was on the margin of a new system and as such we are excited about the further potential. These two holes will be modelled and the continuing Phase 2 drilling programme will focus on open pit extensions and further testing of this newly emerging zone.”
Phase 2 Drilling Progress
Hole BRDD-21-014 was sited to the southeast beyond the limit of the current Racecourse Inferred Mineral Resource and the conceptual open pit area to test a new MIMDAS IP target not investigated by previous drilling at Racecourse. The hole was drilled at -55 degrees towards the northeast and reached a final depth of 816.5m. It intersected what appears to be a new segment of the Bushranger porphyry complex, with significant widths of pyrrhotite-pyrite mineralisation and associated copper sulphides.
Preliminary results received for a drone-mounted airborne magnetic survey in the area suggest that the hole may have cut the margin of the new zone and the final processed magnetic data will be utilised to assist with planning further holes, in tandem with full log and assay data from BRDD-21-014.
The second rig at Bushranger has completed hole BRDD-21-013 within the south-eastern part of the conceptual open pit. The hole was collared at -50 degrees drilling towards the northeast and progressed to a final depth of 855.5m. The main mineralised target zone was intersected at about 84m downhole depth and ran through intervals of moderate to strongly developed copper mineralisation to about 389m depth. After passing through a zone of unaltered and unmineralised black shales, the hole hit a further deep zone of weak potassic alteration with pyrrhotite, pyrite and associated chalcopyrite copper mineralisation at around 800m.
Detailed logging and sampling of drill core continue at site, with core from BRDD-21-007, 008 and 009 now at the assay laboratory.
Following completion of hole BRDD-21-014, the first drill rig has now moved to the northwest and commenced drilling BRDD-21-015.
Phase 2 Drilling Programme at the Racecourse Mineral Resource – Background
The Bushranger porphyry copper-gold project is located in the highly prospective Lachlan Fold Belt (“LFB”) of New South Wales, Australia. The current JORC (2012)-compliant Inferred Mineral Resource on the Racecourse deposit is estimated as 71Mt @ 0.44% Cu and 0.064g/t Au, at a 0.3% Cu cut-off, without inclusion of data from the Phase One drilling programme which was recently concluded and reported.
The Phase Two programme is designed primarily to follow up on the results obtained by Anglo American Exploration Australia Pty Ltd (“Anglo”) in 2014 and 2015 and to define further the shallower part of the Resource with a view to possible development of a large open pit. A total of approximately 8,000m of drilling is planned in the first block of 13 holes using two drill rigs, focussing primarily on further definition of the potentially open-pittable, higher-grade copper-gold zone in the central part of the resource area.
