Noronex Limited (ASX: NRX) has kicked off drilling at the Snowball Project as part of its exploration of its suite of copper projects in Namibia, Africa.
Highlights
• Further Reverse Circulation (RC) drilling underway on the Snowball Project to test the prospective NPF contact across the basement high
• Ground magnetics completed to assist planning holes targeting the magnetic break under Kalahari sands adjacent to potential feeder structures
• Targets generated from modelling of the largest deposits in the Central African Copper Belt and the eastern end of the Kalahari Copper Belt in this basin in Botswana
Snowball Joint Venture Drilling
A programme of six holes has commenced for an estimate of 1,200m on the eastern tenement EPL7415 at Erfenis to test the prospective NPF-D’Kar contact.
The contact has been defined by ground magnetic profiles completed along the length of the basement high.
Drilling will target the contact of oxidised sandstones and reducing siltstone horizons that host the mineralisation further west at Noronex’s Fiesta project in Namibia and the large Zone 5 deposit in Botswana owned by Cupric Canyon.
The area has never been tested due to Kalahari sands of 60-80m depth hindering traditional geological and geochemical exploration.
Kalahari Copper Belt Target
The Kalahari Copper Belt extends for 1,000kms across north-western Botswana into Namibia. The belt is part of an extensive Mesoproterozoic rift system which formed along the margins of the Kalahari craton during the Namaqua-Grenville orogeny.
Stratigraphy displays typical characteristics of a sedimentary copper system, including a basal sequence of bimodal volcanics overlain by red-bed sediments, mixed reduced marine siliciclastic and carbonate rocks.
Copper mineralisation occurs throughout the belt along, and above, the main redox contact between the Ngwako Pan and D’Kar Formations. Mineralisation is largely epigenetic and primarily related to basin inversion during a prolonged mineralising event during the Damara (Pan-African) orogeny. Mineralisation is concentrated on major reactivated structures above basement highs where basinal fluids are concentrated in reductant traps during basin inversion.
Despite the belts emergence as a copper producing district, much of the area remains relatively unexplored due to the presence of extensive Kalahari Group cover.
The Snowball region has had no previous drilling despite having all the hallmarks for a large regional copper producing target. Noronex Limited’s extensive, strategically positioned, licenses place the company in an excellent position for making new discoveries.
