The Husab Project is dominated by a series of north-northeast to northeast trending regionalscale antiforms and synforms, which make up the main structural architecture of the entire Central Zone of the Damara. These meta-sedimentary folds or dome-like structures of the DOB are cored by gneissic and metasedimentary rocks of the Abbabis Formation.

The Husab Uranium Project uranium mineralisation is associated with intrusive alaskite rocks and is informally referred to as a Rössing Type uranium occurrence.

At the Husab Uranium Project, mineralised alaskite occur proximal to the contact between the Khan Formation and calc-silicates of the Rössing Formation. The majority of the uraniferous alaskites are located within the Rössing Formation. The host Rössing Formation can vary from 50m to over 200m wide and mineralised intercepts can vary from a few metres to over 100m wide.

The average width of mineralised horizons is approximately 20m. The mineralisation at Zones 1 to 4 is a near-continuous mineralised area extending across approximately 8km strike length and up to 2km across strike. Individual mineralised units can be traced for several hundred metres along strike and down dip. Metallurgical indicates that uraninite is the main uranium mineral. Elevated uranium grades (for example) associated with beta-Uranophane, an oxidation product of uraninite, have been identified in drillhole RDD002.

In addition to primary alaskite hosted urani ........

The Husab mine has five potential mineralized zones on the property, of which we are currently exploiting two zones – Zone 1 and Zone 2. Both are mined through two open pit operations very close to each other. 

In this area there are six different formations: the Kalahari forms the overburden, below the Kalahari is the Khan and then Chuos, followed by the Rossing, Karibib, and the intrusive layers, which occurs a lot deeper. The ore is concentrated around the Rossing formation. The ore doesn’t seem to occur in any of the formations below the Rossing formation. Two open pits have now reached depths of close to 90m & 140m, respectively.

Both sites are open pit operations. The Company uses a conventional truck and shovel method to mine the ore body, with hydraulic and electric shovels. The mining fleet consists of: six shovels that include three CAT 6060’s Face Shovels and three CAT 7495 Electric Shovels. In total, Company has 26 tracks of which 23 are Komatsu 960 E’s, and three are NTE 330’s which are Chinese manufactured trucks. There are twelve drill rigs in the pit, and here Company also have a combination of diesel and electric rigs – there are three CAT MD6640 electric drill rigs and four CAT MD6290 diesel-driven drill rigs. In addition, Company operate one CAT MD 6650 and four Atlas Copco Rock L8’s. The Rock L8’s are mostly for smaller diameter holes for pre-strip drilling. The hole diameter varies between 127mm for the smaller pre-split holes to 331 ........
