Silverking Project Drilling Update

The Board of Xtract Resources Plc is pleased to report further assay results for the second batch of diamond drillholes completed on the Silverking Project located in the Mumbwa District of the Central Province of Zambia. Silverking is subject to an option and joint venture agreement ("Joint Venture") with Oval Mining Limited, enabling Xtract to earn-in up to a 70% interest in the Silverking copper mine and accompanying exploration licence located in the Mumbwa District of the Central Province of Zambia.

Highlights

• Continued high-grade copper and silver intercepts over significant mineralised widths.
• Borehole SKIDD004: 1.50% Cu & 20.25g/t Ag over 40.2m from 71.80m
• Borehole SKIDD005: 4.73% Cu & 55.08g/t Ag over 3.7m from 68.0m.
• Borehole SKIDD005: 0.58% Cu & 2.31g/t Ag over 27.0m from 107.0m.
• Borehole SKIDD006: 0.56% Cu & 10.33g/t Ag over 3.3m from 69.0m.
• Strike length of the mineralised trend now extended to more than 160m in length.
• Metallurgical test work now extended to include upgrading and pre-concentration of lower grade footwall and hangingwall mineralisation using gravity processes (spirals and jigs) to generate a pre-concentrate for final processing at a centralised facility.
• Amenability of lower grade mineralisation has the potential to materially increase production tonnage and copper output subject to successful test work.

Colin Bird, Executive Chairman of Xtract, commented: "The latest results have doubled the strike extent of the high-grade mineralisation to more than 160m. We will continue to step out drilling until we reach the limits of mineralisation and at the same time will continue to test the depth of mineralisation with selected deeper drilling to approximately 400 vertical metres. The scope of the metallurgical test work has been expanded and we are working with metallurgical engineers that have had very exciting results upgrading lower grade copper mineralisation through conventional gravity processing to produce a pre-concentrate for suitable final concentration processes. This could be significant as our high-grade orebody is typically associated with a lower grade mineralised envelope that may be treatable offering additional copper production. We will continue to update shareholders as new assay data is generated".
