21 Oct Bushranger Project Assay Results
Xtract Resources plc 21 October 2021 (“Xtract” or the “Company”) Bushranger Project Assay Results
The Board of Xtract Resources Plc (“Xtract” or the “Company”) is pleased to advise that independent laboratory assays have been received from the third drill hole (BRDD-21-009) completed on the Phase 2 diamond drilling programme at the Racecourse Mineral Resource on the Bushranger copper-gold exploration project.
· Drill hole BRDD-21-009 returned a very wide intersection of 448m @ 0.30% CuEq from a depth of 272m (see Table 1) including:
§ 155m at 0.44% CuEq from 343m
§ 35m at 0.61% CuEq from 363m
§ 28m at 0.54 % CuEq from 470m
· The results from drill hole BRDD-21-009 indicate that the mineralisation intersected in hole BRDD-21-007 (see RNS dated 7 October 2021) increases in width at depth, while the higher-grade intervals correlate extremely well from hole BRDD-21-007 to hole BRDD-21-009, indicating good continuity of the higher-grade copper zones.
· As with the results for BRDD-21-008 (see RNS dated 28 September 2021), a gold-rich zone was encountered at 630m depth which returned an overall interval of 8m at 0.85 g/t Au and best gold result of 2m at 1.92 g/t Au from 634m.
Colin Bird, Executive Chairman said:
“The results from hole nine demonstrate a wide intercept of mineralisation, within which are very favourable sub-runs, all of which fall within the requirements for the development of a porphyry copper mine. Interestingly, hole nine also intercepted a gold-rich zone. We are pleased with the consistency of the results we are receiving, all which support the prognosis of a large open pit operation.”

Drill hole BRDD-21-009 was drilled to test the down dip extension of mineralisation intersected in drill hole BRDD-21-007 and to target a low resistivity zone at depth which was interpreted as a probable pyrrhotite zone with associated chalcopyrite copper mineralisation. While drill hole BRDD-21-007 was designed to intersect the top or “crown” of the porphyry system where copper grades are enhanced at relatively shallow depths, BRDD-21-009 was designed to provide information on the depth extent and width of the copper mineralisation deeper in the porphyry system.
The drillhole successfully intersected the down dip continuation of the copper mineralisation encountered at shallower depths in drill hole BRDD-21-007. The high-grade zones correlate well from hole BRDD-21-007 to hole BRDD-21-009, the interval of 38m @ 0.69% CuEq in hole BRDD-21-007 corresponds with an interval of 35m @ 0.61% CuEq in hole BRDD-21-009, suggesting good continuity of the higher-grade zones at depth. The copper mineralisation intersected in hole BRDD-21-009 is open both down-dip and along strike.
An 8m wide gold-rich horizon was intersected at a depth of 630m downhole, the overall intersection contains 0.85 g/t gold, and the highest assay returned 2m at 1.92g/t Au from 634m.
Assay results from the first three holes of the Phase 2 Racecourse deposit drilling programme suggest that the higher-grade copper zones are associated with increased pyrrhotite-chalcopyrite mineralisation, which manifest as resistivity lows in the Induced Polarisation data collected in May 2021 (refer to RNS 17 May 2021). Therefore, the strategy of targeting drilling on resistivity low zones has provided very encouraging intersections of copper mineralisation to date.
