Botswana: Arc Minerals Ltd commences with Maiden Botswana Exploration Programme

Arc Minerals Africa focussed copper company is pleased to report the commencement of its maiden exploration programme at its Virgo Project in Botswana, with a soil geochemistry survey currently underway to be followed by an exploratory drill programme.


·  Re-interpretation of the geology in license PL 135/2017 suggests the existence of a fold crest that presents a good opportunity to extend the previous soil sampling grid along the fold limb to this crest

·    Both PL 135/2017 & PL 162/2017 license areas host the contact between Ngwako Pan (“NPF”) and D’Kar (“DKF”) Formations that are favourable for hosting Cu-Ag mineralisation

·   The historically sampled areas within the two licenses indicate DKF-NPF contact and further sampling will assist to zone in on this contact

·  Exploration drilling to follow and test DKF-NPF contact zone areas as well as interpreted fold crest targeting the known and any new anomalies that may be generated from the soil geochemistry survey

Nick von Schirnding, Executive Chairman of Arc Minerals, commented:

“Following the acquisition of Alvis-Crest (Propriety) Limited late last year the team has reviewed the previous work carried out in the respective license areas and put forward our maiden exploration programme to further refine our geological understanding before commencing with an exploratory drill programme.

These licenses lie within and adjacent to the highly prospective Central Structural Corridor of the Kalahari Copper Belt (“KCB”) and within 10km and 50km of Khomecau’s Zone 5 and Banana Zone copper projects respectively, known as the two largest copper projects on the KCB.

Further these licenses already host two known copper-nickel anomalies, both 2-3km in length overlying the favourable interpreted DKF-NPF contact that have yet to be drill tested and now potentially may have further targets. This is an extremely exciting time for the Company and these license areas.”

Background to the Soil Geochemistry Survey

The previous soil geochemistry survey across the Virgo Project (“Virgo”) that consists of PL 135/2017 & PL 162/2017 license areas, provided encouraging results for potential mineralisation along the DKF-NPF contact.

PL135/2017 License Area

At the PL 135/2017 license area, the reinterpretation of the geology, mostly under cover of the Kalahari Sands, suggests the existence of a fold crest running through the middle of the license area, with favourable soil geochemistry that itself is already a target of interest.

Furthermore, the southern limb to this interpreted crest runs adjacent to Khomecau’s Zone 9 exploration target, which is located on the edge of the Virgo license boundary, which supports extending the soil geochemistry survey along this interpreted limb towards Zone 9.

A total of nine lines averaging 1,000m long are being sampled at 25m intervals along the survey line and samples collected sent off for analysis.

PL162/2017 License Area

Similarly, at this license area, reinterpretation of the geology has refined geological understanding and position of the DKF-NPF contact, indicating the need complete a soil geochemistry survey in the south-eastern margin of the license area.

A total of seven lines averaging 500m long will be sampled at 25m intervals along the survey line and sampled collected sent off for analysis.

About the Virgo Project

In November 2021, Arc Minerals Limited acquired a 75% interest in Alvis-Crest (Proprietary) Limited, the holder of two prospecting licences (PL 135/2017 & PL 162/2017) in Botswana’s Kalahari Copper Belt (“KCB”), colloquially called the Virgo Project/Licences. These licenses, cover and area of over 210km2, with PL 135/2017 approximately 10km south east of the large underground Khoemacau Copper mine recently commissioned by Cupric Canyon Capital LP.

Please see the below link to a map of the licences:

The Virgo Licenses cover an area of over 210km2 and lie within (PL 165/2017) and adjacent (PL 135/2017) to the highly prospective Central Structural Corridor and within 10km and 50km of the Zone 5 and Banana Zone copper projects respectively, known as the two largest copper projects on the KCB.

Historically, two copper-nickel soil anomalies have already been recorded on PL 135/2017 and PL 162/2017 and are approximately 3km and 2.5km in strike length respectively. The largest of the two anomalies, located on PL 135/2017, overlays an interpreted DKF-NPF contact, while a second more intermittent anomaly may be linked to extensional faulting around the dome edge. The large coherent anomaly on PL 162/2017, also appears to overlay the interpreted DKF-NPF contact on the northern limb of a syncline.
