Ascot Prospect Final Assay Results

The Board of Xtract Resources Plc (“Xtract” or the “Company”) is pleased to announce assay results for follow up drill holes BRDD-22-051, BRDD-22-052 and BRDD-22-055, which were drilled to further investigate the copper-gold intersections in drill hole BRDD-21-035 which represented the discovery hole at the Ascot porphyry system on the Bushranger Project in central New South Wales, Australia. The holes were planned in particular to check the up-dip projection of the intersections in BRDD-21-035 where mineralisation might be potentially amenable to open pit extraction.  The drilling completed by Xtract throughout 2021 and 2022 has confirmed the presence of two significant porphyry systems at the Racecourse and Ascot prospects on the Bushranger Project. 


·    Drill hole BRDD-21-051 was drilled above hole BRDD-21-035, at a shallower inclination, and intersected the Zones 2 and 3 of copper-gold mineralisation as follows:

§ 18m @ 1.8% CuEq from 432m (Zone 3) – amongst the highest grade intervals intersected to date on the overall Bushranger Project

§ 8m @ 0.12% CuEq from 278m and 18m @ 0.12% CuEq from 292m and (Zone 2)

·    Drill hole BRDD-22-052 was drilled from the west to east, whereas drill hole BRDD-21-035 was drilled east to west, and intersected copper-gold mineralisation as follows:

§ 16m @ 0.49% CuEq from 419m (Zone 3)

§ 18.16m @ 0.25% CuEq from 493m (Zone 2)

§ 8m @ 0.23% CuEq from 652m (Zone 1)

·    Hole BRDD-22-055 was drilled to test the Ascot mineralisation at depth; due to drilling issues the hole was not completed as planned, but did intersect 63m @ 0.22% Cu Eq from 616m downhole depth, including 4m @ 1.07% Cu Eq at the top of this zone

·    The copper-gold mineralisation intersected in the Ascot drill holes is laterally extensive and has been traced over 1km of strike in a north-south direction

·    Xtract is currently compiling a geological model of the copper-gold mineralisation at Ascot with the objective of defining a maiden Mineral Resource Estimate for the Ascot prospect

Colin Bird, Executive Chairman said: “The Ascot prospect continues to produce some very encouraging drill intersections. The 18m @ 1.8% CuEq is amongst the highest grade copper intersections on the overall Bushranger Project and it confirms that the excellent intersection of 64m @ 0.58% CuEq (Zone 3) in drill hole BRDD-21-035, continues to shallower depth. The results from holes BRDD-21-051, 52 and 55, when combined with the results of other holes we have released from the Phase 2 drilling programme at the Ascot prospect, show that the copper-gold mineralisation at Ascot is laterally extensive, extending over approximately 1km of strike. It is also worth noting that the higher grade copper mineralisation in Zone 3 at Ascot is open both up and down dip and to the south.  We are now working on the overall geological model for Ascot, which will then be used to produce a maiden Mineral Resource Estimate for the Ascot Prospect. This will be in addition to the updated Racecourse mineral resource estimate which is close to completion.”

Ascot Prospect Drill Hole Assay Results

Drill hole BRDD-21-035 was the second hole drilled into the Ascot discovery, situated 1.5km to the south-east of the centre of the Racecourse prospect and followed up the encouraging results recorded in drill hole BRDD-21-033, the discovery hole at Ascot (see announcements dated 19 January 2022 and 9 December 2021).  BRDD-21-035 returned three zones of substantial copper and gold mineralisation including;

§ 66m @ 0.26% CuEq from 166m including 18m @ 0.39% CuEq from 194m (Zone 1)

§ 52m @ 0.26% CuEq from 356m including 8m @ 0.52% CuEq from 394m (Zone 2)

§ 164m @ 0.35% CuEq from 552m including 64m @ 0.58% CuEq from 552 (Zone 3)

BRDD-22-051 was drilled at an inclination of -50 degrees towards the west (azimuth of 267o true north) and was completed at a final depth of 555.3m.  It was drilled primarily to intersect the Zone 2 and Zone 3 intersections from drill hole BRDD-21-035, but at shallower depths (see assay results in Table 1).

BRDD-22-052 was drilled at an inclination of -55 degrees towards the east (azimuth of 102o true north) and was completed at a final depth of 704.5m. This hole was drilled to cut the Zone 3 intersection from drill hole BRDD-21-035 at shallower depth above that hole and to intersect the Zone 1 mineralisation at greater depth below drill hole BRDD-21-035 (see assay results in Table 2).

BRDD-22-055 was drilled from west to east to test the deeper mineralisation below the Zone 3 intercept in hole BRDD-21-035. It intersected a 63m interval of moderate copper/gold mineralisation (see assay results in Table 3) but the hole was truncated due to drilling difficulties without testing the full planned target interval.

In summary, three steeply dipping, sub-vertical zones of copper-gold mineralisation were intersected in holes BRDD-21-035, BRDD-22-051 and BRDD-22-052 at the Ascot prospect which are open up and down dip and along strike to the south.

The intersection in hole BRDD-22-051 of 18m @ 1.8% CuEq from 432m (Zone 3) occurred 170m up dip of the intersection of 64m @ 0.58% CuEq in drill hole BRDD-21-035 suggesting that high grade copper mineralisation does extend closer to surface and potentially within depths which would be amenable to open pit extraction.

In addition to the Ascot drilling, two exploration drill holes, FTDD-22-001 and 002 completed at the Footrot prospect, about 7km south-southeast of Racecourse, intersected lengthy intervals of alteration and iron sulphide mineralisation along with traces of copper and possible gold indicator minerals. This could suggest proximity to a mineralised porphyry – further modelling of the geophysical results here will be required.

Xtract is now incorporating all the geological and geochemical data from the Ascot prospect into a geological model which will be used to estimate a maiden Mineral Resource (JORC 2012) for the Ascot prospect. In tandem with this, a revised resource estimate is in preparation for the Racecourse deposit. This will then be used as the basis for an updated conceptual open pit mining study.
