Bushranger Project Assay Results and Phase 2 Drilling Update

 

The Board of Xtract Resources Plc ("Xtract" or the "Company") is pleased to report on independent laboratory assays for drill hole BRDD-021-016 and two further holes completed on the Phase 2 diamond drilling programme at the Bushranger copper-gold exploration project.

 

Highlights

 

· Drill hole BRDD-21-016 has returned promising intersections of copper and gold mineralisation near the southern limits of the currently estimated Racecourse Inferred Mineral Resource

· Assay results include 14m at 0.39% CuEq from 250m depth within a wider zone of 142m at 0.21% CuEq from 170m (details in Table 1 below)

· Elevated gold values (40m @ 0.23g/t Au from 596m) below the main Racecourse porphyry body, along with a coincident IP anomaly, suggest that a secondary porphyry body may occur at depth below the main Central Porphyry Intrusion

· Drillhole BRDD-021-026 tested the extension of mineralisation at depth on the western side of the central part of the Racecourse deposit. Based on preliminary logging and subject to laboratory assays, variable strength chalcopyrite mineralisation occurs over a 282.5m interval from 367m downhole

· Drillhole BRDD-021-027 was the second hole of the Phase 2 drilling programme drilled with a westerly azimuth and is interpreted to have passed close to the high-grade "crown" at the top of the intrusion. Based on preliminary logging and subject to laboratory assays, the hole intersected a 371m down hole interval of variable strength visible copper mineralisation from 97m depth

Colin Bird, Executive Chairman said: "The results of hole BRDD-21-016 have again showed good runs of copper grade, with mineralisation over a 142m interval, of interest was a secondary zone of gold intercepted at 596m, which graded up to 8m at 0.66 g/t Au. The mineralisation in hole 16 was intersected at depth and below the crown, although it appears that gold manifests at deeper levels. The recent drilling results suggest that the copper mineralisation extends further south than indicated by the mineral resource model and the results give us increased encouragement for the potential of the orebody to progress further south, or indeed, new porphyry systems to be discovered."

Drillhole BRDD-021-016 was designed test the extension of mineralisation in the modelled Racecourse deposit towards the south and was drilled at an inclination of -70 degrees towards the east (refer to RNS dated 14 September 2021). Assay results have confirmed an overall interval of 142m grading at 0.21% CuEq from 170m downhole, at today's metal prices, and, within the larger interval, the copper values grade up to 14m at 0.39% CuEq from 250m downhole.

 

A relatively broad zone of elevated gold was also intersected at depth, including a 40m downhole interval which graded 0.23g/t Au and included 8m at 0.66 g/t Au from 628m downhole. This zone occurs on the eastern side of the Central Racecourse mineralised porphyry body and has not been significantly drill tested to date. The area is proximal to an induced polarisation resistivity low anomaly and could signify that a second mineralised porphyry body is close by at depth. Further drilling to test this zone has been planned as part of the second stage of the Phase 2 drilling programme (Refer to RNS dated 13 October 2021).

 

Bushranger Phase Two Drilling Update - Drill Holes BRDD-21-026 & BRDD-21-027

Drill hole BRDD-21-026 was drilled at an inclination of -60 degrees towards the east and was completed at a final depth of 678.4m. The hole was drilled into the side of the Central porphyry body and it was designed to test the extension of the mineralisation at depth in the main central zone of the Racecourse porphyry deposit. Based on preliminary logging and subject to laboratory assays, visible chalcopyrite was first logged from 177m downhole, with a 282.5m downhole interval of variable strength copper mineralisation occurring from 367m downhole.

Drill hole BRDD-021-027 was the second drillhole of the Phase 2 programme drilled with a westerly azimuth. The hole was designed to test the high-grade "crown" at the top of the Racecourse porphyry system and the along strike continuation of the Racecourse deposit further to the south. The hole was drilled at an inclination of -80 degrees and completed at a final depth of 580m. Based on preliminary logging and subject to laboratory assays a 371m down hole interval of variable strength visible copper mineralisation was intersected from 97m downhole. This is interpreted to extend the mineralisation drilled in hole BRDD-021-024 by 300m further to the southeast (refer to RNS 9th November 2021).

Further holes have been planned to test the along-strike continuation of the Racecourse porphyry system further towards the south and these holes are currently in progress.
