Exploration Update over Kalahari Copper Belt Licences Sold Pursuant to Agreement with Sandfire Resources Limited

Galileo Resources plc (‘Galileo” or the “Company”) is pleased to provide an update on the Kalahari Copperbelt Project in western Botswana and work undertaken and planned on those licences sold pursuant to an agreement (see RNS dated 16 September 2021) with Sandfire Resources Limited (“Sandfire”) (the “Sandfire Licences”).

Encouraging results are attributable to several licences where Sandfire is exploring for typical Kalahari Copperbelt style mineralisation and follow-up exploration has been recommended by Sandfire. Interpretation of airborne magnetic and radiometric surveys by Sandfire and subsequent drilling on the Okwa Project covering licences PL044/2018 and PL045/2018 has identified disseminated sulphides, including copper, in intermediate and felsic volcanics.


·    Work has been undertaken on prospecting licences PL044/2018, PL045/2018, PL122/2020, PL154/2018, PL251/2018, PL366/2018 and PL367/2018

·    PL250/2020 – approximately 7.24km of prospective Lower D’Kar contact has been identified warranting a TerraleachTM* soil geochemical survey. Area will also be covered by regional airborne gravity survey (‘AGG’)

·    PL367/2018 – Four multi-element soil anomalies identified as priority targets with infill TerraleachTM soil surveys planned.

·    PL251/2020 – Scheduled TerraleachTM* soil survey over an area described by Sandfire as a T3/A4-type target. AGG survey also to be flown.

·    PL366/2018 – Soil anomaly identified warranting additional soil geochemistry in conjunction with Sandfire’s announced AGG regional survey.

·    PL044/2018 & PL045/2018 – Airborne magnetic and radiometric geophysics and follow up drilling confirmed the presence of magnetite and disseminated copper-zinc mineralisation in intermediate to acid volcanic rocks – follow up under review.

·    PL122/2020 & PL154/2020 – Considered low order priorities with no additional work planned in the short to medium-term subject to results of the pending AGG survey.

*TerraleachTM: The technique is a partial leach method that assays for mobile ions which have migrated into the weathering zone, and which are only weakly or loosely attached to the surfaces of soil particles. Studies have shown that these ions have the ability to disperse through unmineralized rock (e.g. hundreds of metres vertically) possibly by micro-bubble, vapour, ground-water flow, capillary rise, or electrochemical processes. The technique therefore has the capacity to indicate buried mineralisation.

Colin Bird Chairman and CEO commented “A considerable amount of work has been completed on the Sandfire Licences and the results to date are very encouraging. In terms of the Kalahari Copperbelt type mineralisation, multiple targets have been identified for follow up and we look forward to the next round of results generated by Sandfire.

There is intense activity in the Kalahari Copperbelt with traditional thought being overtaken by new concepts and new ideas which are being proven in practice. The Sandfire Licences and our retained licences which were not sold to Sandfire are all in pole position relative to the activity which should help accelerate our efforts”.



Airborne magnetics has indicated the presence of Lower D’Kar stratigraphy and an approximate 7.24km of strike length of Lower D’Kar contact which is considered prospective. Soil surveys are planned over the area using the TerraleachTM* process. The licence will also be covered by the AGG airborne gravity survey previously announced by Sandfire.


The Mokoro prospect has been soil sampled resulting in the discovery of four priority multi-element anomalies warranting follow up. Infill soil programmes have been planned.     


Lower D’Kar lithology is interpreted to occur within the licence although no Lower D’Kar geology has been identified at surface. Potential for T3/A4-style of mineralisation will be covered by a TerraleachTM* soil survey. The Licence will also be covered by the scheduled AGG survey.


An historic soil anomaly located along the southern boundary of the Licence has been re-investigated by Sandfire (designated as the T15 Target) and warrants a new soil survey prior to drill testing. The Licence will also be covered by the AGG survey. 

PL044/2018 & PL045/2018

Sandfire has drilled a total of nine drillholes on the Okwa Project, two diamond drillholes and seven reverse circulation holes of which four were also subject to downhole EM geophysical surveys. This identified a magnetite-bearing intermediate to acid volcanic system with disseminated chalcopyrite mineralisation.

Sandfire is now considering the next stage of exploration over the two licences.

PL122/2020 & PL154/2020

Recent interpretation of new magnetic data indicates the absence of prospective geology on these two licences and no further work is scheduled in the short to medium-term. The upcoming AGG survey may indicate potential which would then be investigated on merit.
