SnapshotAll Environmental Clearance Certificates and National Heritage consents have been received and the Etango Project is fully permitted in this regard.

The Etango Mining Licence (ML) application was submitted to the Ministry of Mines and Energy (MME) in August 2022. Following the submission of the DFS in December 2022, Bannerman has been working with the MME towards grant of the ML.

Bannerman’s strategy remains unchanged: advancing FEED and other key workstreams on Etango to deliver the currency of quotation and overall development shovel-readiness while maintaining strong balance sheet liquidity and strategic patience with respect to the satisfaction of key external factors.

This approach, along with favourable uranium market conditions, is advancing Etango towards a targeted positive Final Investment Decision, uranium market permitting, during H1 CY2024. Construction of the Etango Project is expected to take approximately 34 months (including detailed design).

Summary:

Primary uranium mineralisation in the Etango-8 Project area is related to uraniferous leucogranites, locally referred to as alaskites. The alaskites are often sheet-like, and occur both as cross-cutting dykes and as bedding and/or foliation-parallel sills, which can amalgamate to form larger, composite granite plutons or granite stockworks, made up of closely-spaced dykes and sills. These alaskite intrusions can be in the form of thin cm-wide stringers or thick bodies up to 200 m in width.

The alaskite bodies have intruded into the metasediments of the Nosib and Swakop Groups of the Damara Supergroup. These metasediments and alaskite intrusions flank the Palmenhorst Dome which is cored by Mesoproterozoic (1.7 2.0 Ga) gneisses, intrusive rocks and meta-sediments of the Abbabis Metamorphic Complex.

Uranium mineralisation in the Etango-8 Project area occurs almost exclusively in the alaskite intrusives. Minor uranium mineralisation is also found in the metasedimentary sequences close to the alaskite contacts, probably from metasomatic alteration and in minor thin alaskite stringers within the metasediments.

The dominant primary uranium mineral is uraninite (UO2), with minor primary uranothorite ((Th,U)SiO4) and some uranium in solid solution in thorite (ThO2). The uraninite is commonly associated with chloritised biotite in the alaskites and with ilmenite and magnetite within foliated alaskites. The primary uranium mineralisation occurs as microscopic disseminations throughout the alaskite, at crystal interfaces, and as inclusion within other minerals. Secondary uranium minerals such as coffinite (U(SiO4)(OH)4) and betauranophane (Ca(UO2)2(SiO3OH)2 5H2O) occur as replacements of the primary minerals or as coatings along fractures.

QEMSCAN analysis indicates that about 81% of the uranium present is in primary uraninite, while 13% is in secondary coffinite and 5% is in secondary betauranophane (Freemantle, 2009). The remaining 1% of the uranium occurs in various minor phases including brannerite, betafite and thorite. Very minor amounts of uranium are also present in solid solution in monazite, xenotime and zircon. A very minor amount of primary betafite (Ca,U)2(Ti,Nb,Ta)2O6(OH) is also present.
