For immediate release

Xtract Resources Plc
("Xtract" or the "Company")
Zambia Copper Exploration Update
 
The Board of Xtract Resources Plc ("Xtract" or the "Company") is pleased to provide an update on exploration works on the copper / gold  small scale mining license number 8370-HQ-SML ("Licence") located at Kajevu, Kasempa, North Western Province in The Republic  of Zambia ("Matrix Project"), as well as its Eureka project on the copper-gold small scale mining licence number 22134-HQ-SML (" Eureka Licence") located in the Central part of The Republic of Zambia ("Eureka Project").
 
Highlights
 
·    Exploration work commenced on Matrix Project
·    Soil sample results suggest that quartz-hematite breccia zone may be copper-mineralised for over 600m westwards from previous open pit mine
·    Accompanying elements particularly potassium indicate larger zone of alteration up to 2.5km long
·    Contract signed for magnetic survey to delineate sub-surface extent of alteration/mineralisation
·    Eureka visited and large data bank acquired for analysis
·    Conclusion from visit and data interrogation to be digitised with a view of selecting targets
 
Colin Bird, Executive Chairman said: "This is a very good start to our preliminary exploration programme and I am particularly pleased with the relatively high potassium trend potential indicating alteration. The apparent mineralised zone is quite wide and the magnetic survey currently under way will hopefully further assist in targeting our proposed drilling programme. A further visit to the Eureka project and an archive search made it very clear that Eureka is drill-ready. The proposed digitising of all information will greatly assist the targeting of drill-holes".
 
Summary of work completed
Preliminary exploration work by Xtract commenced on the Matrix Project in April 2019 where previous bedrock sampling and small-scale mining confirmed the presence of strong copper-gold mineralisation (as previously announced on 11 February 2019). A Southern / Central African based consulting and services company, GeoQuest Limited, was commissioned to carry out a soil sampling survey on a 100 x 50m grid. 789 samples were collected and sieved on site, where they were analysed using a hand-held XRF spectrometer for a range of elements, including copper and associated minerals, but excluding gold which cannot be accurately detected by this methodology.
 
Results returned values up to 177ppm Cu close to the vicinity of the copper-gold mineralisation in the former open pit, above an anomalous threshold of 25ppm Cu. It was noted that anomalous values extend for over 600m to the west as far as the licence boundary. This coincides with the mapped extension of the IOCG-type quartz hematite breccia zone which has been mined in the open pit. The soil geochemistry provides encouragement that the zone may be copper-bearing in the unmined area to the west where near-surface leaching appears to mask mineralisation.
 
Accompanying elements, including iron and potassium, show a marked east-west trend over a strike of up to 2.5km which may reflect a more extensive alteration zone surrounding the main mineralised structure.
 
In the southeast sector of the licence, some further trends were discernible from the geochemical data, while it appears that the small mineralised artisanal pit in this area may be part of a separate structure to that worked in the main pit.
 
At the Eureka Project the Company has acquired an extensive historic exploration database and is currently compiling and reviewing the data to guide future exploration, with a primary focus on the two areas of high grade copper-gold mineralisation already identified.
