Kraaipan Project

Highlights

• Covers the entire ~60 km northern extension of the Kraaipan Greenstone Belt (“KGB”) in Botswana.
• On trend from the multi-million ounce Kalgold Mine in South Africa (historical production plus current resources); other significant greenstone belt related deposits in the area.
• > 80% of the KGB in Botswana is covered by Kalahari sands so very poor exposure for exploration; modern exploration techniques to allow for assessment of previously overlooked areas.
• A first-pass 3,800m Rotary Air Blast (RAB) drill program in the late-90’s confirmed anomalous gold mineralisation over a 10 km strike length of outcropping & interpreted iron formation.

Overview

The Kraaipan Gold Project encompasses 724 km² of land concessions covering a 60 km strike length of the Archaean Kraaipan Greenstone Belt ("KGB") within Botswana. This extensive area is largely concealed beneath younger Kalahari sediments, creating a geological setting that is highly prospective yet underexplored due to the sand cover.

The KGB extends for over 200 km, stretching from South Africa northward into Botswana. The South African portion of the KGB is known to host significant mineralization, including Harmony Gold's Kalgold mine, located approximately 40 km south of the Botswana border. This proven mineralization in the southern extension of the belt underscores the exceptional potential of our project area.

North Arrow is earning a 60% interest from Rockman Resources in this promising gold exploration opportunity. By applying modern exploration techniques and implementing a belt-wide systems approach, North Arrow and Rockman are thoroughly testing the potential of the KGB to host similar mineral deposits within the 60 km strike extent in Botswana.

Our exploration targets include orogenic gold deposits similar to those found in the South African portion of the belt, as well as magmatic Ni-Cu-PGE deposits that may be present in this Archaean geological setting.

Strategic Advantage

The sand cover of the Kalahari Desert has historically limited exploration in this northern extension of the KGB, effectively preserving a frontier opportunity in an otherwise well-established gold-producing geological formation. Rockman and North Arrow are working together as a technical team employing cutting-edge exploration methods specifically designed to identify promising targets beneath this cover.

Our systematic approach combines high-resolution UAV magnetic surveys, detailed structural mapping to best understand the mineralization criteria, and targeted drilling programs to efficiently evaluate this underexplored terrain. This comprehensive exploration strategy positions North Arrow to potentially make significant discoveries in one of Africa's most stable and mining-friendly jurisdictions.

12 Month Exploration Plan

High-resolution (25 m line-spacing) UAV magnetic surveys – Complete (for summer 2025 program)

• Completed high-resolution mag surveys (25 m linespacing) of the project area focus for summer 2025 using Remote Mapper; a portion in the property's north remains to be flown.

Structural mapping of southern property area BIF outcrops –  Complete

• Detailed structural mapping and interpretation to understand the deformation event(s) most likely to be associated with gold mineralization.
• Update geological mapping and definition of prospective regions to identify & prioritise targets for drilling & sampling; target generation

RC Drill testing of compelling BIF & structurally hosted gold targets (May-August) – underway

• Build on RC drill holes completed in 2024 testing bedrock and base of Kalahari sands in a new target areas.
• Focus on areas with <40 m of Kalahari cover
• Test prioritized targets with overburden reverse-circulation drilling (~150 to 200 drillholes)
• Sampling the “base of Kalahari” and bedrock for Au & pathfinder elements by multi-element geochemistry

Additional reverse-circulation and core drilling (H2 2025)

• Target key prospective targets to constrain geology and mineralization
• Program design based on results from overburden drilling and soil sampling

Geology

Greenstone belts are found within every Archean craton (2.5 to 4 billion years old) and reflect the very early stages of the earth’s tectonics and continent formation. They are very often associated with precious and base metal deposits (e.g. Au, Ag, Ni, Cu, Zn) originating from metal rich volcanic rocks and subsequent magmatic activity.  The Abitibi Greenstone Belt in Canada is a very prolific example.  

The KGB extends over a 200km strike length from northern South Africa northwards into Botswana, and is comprised of meta-volcanosedimentary rocks deposited between 3.64Ga and 3.1Ga (Nkomo, 2020).  Where exposed, these rocks are characterised by chlorite-actinolite-epidote alteration assemblages, typical of greenstone rocks.  Approximately 80% of the 60km strike extent of the KGB in Botswana is covered by the sands of the Kalahari Desert. As a result, the Botswana hosted portion of the KGB remains poorly understood and has seen only limited past exploration.

The volcanosedimentary rocks of the KGB, known as the Kraaipan Group, make up the majority of the belt. The Kraaipan Group rocks are not well understood but consist predominantly of mafic metavolcanic units interlayered with iron- and silica-rich metasedimentary rocks.

Granitoid intrusions were emplaced episodically throughout the formation of the KGB. Such intrusions are typical features of greenstone belts and are often associated with the formation of mineral deposits. The intrusive relationship between the granitoids of the KGB and the Kraaipan Group supracrustal rocks is poorly understood due to limited exposure.  however the granites typically contain xenoliths of Kraaipan Group amphibolites and banded iron formation confirming their younger age (Anhaeusser and Walraven, 1997).

Outcrop of the KGB within the Kraaipan Project area is limited to the roughly north-south trending Mosi ridge and a few local exposures along the Molopo River that forms the international border between South Africa and Botswana. The Mosi ridge is comprised of a series of discontinuous, grass covered hills comprised of banded iron formation (BIF).

Gold mineralisation was identified from rock-grab samples and drill intersections over the Mosi ridge by previous exploration companies. Highlights reported from 1990s-era drilling completed by Reunion Mining included 42m @ 0.6g/t Au, 21m @ 1g/t Au, 9m @ 1.6g/t Au and 3m @ 5.1g/t Au. Gold mineralisation is typically associated with BIF-hosted quartz-carbonate veins, similar to those of the +3.5Moz Kalgold mine, approximately 40 km south and along trend of the Kraaipan Project in South Africa.
