Bushranger Copper/ Gold Project Drilling Programme – Further Update


The Board of Xtract Resources Plc (“Xtract” or the “Company”) is pleased to provide a further update on the Phase One diamond drilling programme at the Racecourse Mineral Resource on the Bushranger copper-gold exploration project located in the Lachlan Fold Belt (“LFB”), New South Wales, Australia.



  • Drilling of the first of three holes on the Phase One Drilling Programme at the Racecourse Mineral Resource on the Bushranger Project, has now progressed to a depth of 804m in drill hole BRDD-20-001
  • Copper mineralisation commenced in drill hole BRDD-20-001 at a depth of 110m and has become stronger as the hole has continued to the current depth of 804m
  • The copper mineralisation is predominantly disseminated chalcopyrite (copper sulphides) within a strongly altered quartz-feldspar porphyry intrusive body
  • Drilling operations are continuing to progress at a significant pace with drill hole BRDD-20-001 advancing at a rate of 80-90m per 24-hour period
  • As well-developed copper mineralisation in drill hole BRDD-20-001 is continuing towards the original planned hole depth of 815m, drilling will continue until the mineralisation is drilled through
  • The Phase One drilling programme will comprise three diamond drill holes for a total of 2,290m, with the objective of extending the copper-gold mineralisation beyond the current boundary of the Mineral Resource of 71Mt @ 0.44% Cu & 0.064g/t Au, at a 0.3% cut-off, which has been classified as Inferred in accordance with JORC (2012)


Colin Bird, Executive Chairman said: “The hole is continuing in strong mineralisation of various styles to the current depth, which is very encouraging for the scale of the porphyry system at Racecourse. We will continue to drill until we bottom out of the zone.”


Hole BRDD-20-001 Drilling Results to Date

The Phase One drilling programme commenced on 16 December 2020 with angled hole BRDD-20-001 laid out to track the plunge of the copper-gold porphyry deposit to a planned finishing depth of 815m. Drilling has been advancing rapidly at a rate of 80-90m per 24-hour period. On 12 January 2021 it was announced that the hole had progressed to a depth of 607m and remained within the copper mineralised deposit envelope. The hole has now reached a depth of 804m and, as it continues to encounter strong potassic alteration and copper mineralisation, it will be extended until it passes out of the mineralised zone.

Copper mineralisation occurs as disseminated chalcopyrite (copper sulphides) accompanied by pyrite and pyrrhotite within a strongly altered quartz-feldspar porphyry intrusive body. Mineralisation was first intersected at a downhole depth of 110m and has been evident in core continuously to the current depth, increasing in intensity in the lower part of the interval.

The Company is using a hand-held pXRF Analyser to provide preliminary indications of copper content and samples for definitive geochemical assay will be submitted to the geochemical laboratory on a progressive basis.


Phase One Drilling Programme Plan at the Racecourse Mineral Resource – Bushranger Project

The Xtract Phase One drilling programme at the Racecourse Mineral Resource has been designed to follow up on the very encouraging results obtained by Anglo American Exploration Australia Pty Ltd (“Anglo”) in 2014 and 2015 (refer to RNS released on 01 June 2020). The objective of the programme is to continue to extend the highest-grade copper-gold intersections to the north-west, beyond the limits of previous drilling and to investigate the copper-gold zonation within the Racecourse Mineral Resource.  The initial phase of drilling will comprise three Priority 1 drill holes for 2,290m. Providing encouraging results are received from the Priority 1 drill holes, a further six Priority 2 holes will potentially be drilled for an additional 3,995m. At 71Mt @ 0.44% Cu and 0.064g/t Au, at a 0.3% Cu cut-off, the Racecourse Mineral Resource within the Bushranger Project, is one of the largest undeveloped porphyry copper-gold deposits in the Lachlan Fold Belt.
