Figure 1: Horomela Prospecting Rights Map
Horomela Investments (Pty) Ltd currently hold four prospecting rights that are over 150 000 ha in extent and these prospecting rights are in the vicinity of the world renowned Black Mountain Mine and the Gamberg Project. The location of the prospecting areas are shown in Figure 1 and summarised in Table 1. The prospecting rights are mainly held for lead (Pb), and zinc (Zn) with associated minerals like; nickel (Ni), manganese (Mn), copper (Cu), iron (Fe), cobalt (Co), silver (Ag), and barium (Ba).

The Horomela prospecting licences are located in the structurally complex and poly-metamorphosed Namaqua Province of western South Africa. The licences are underlain by rocks of the Bushmanland Group that mainly consists of pelitic and psammitic metasediments. The supracrustal rocks of the Bushmanland Group, comprise a thin (<1 km thick) metavolcano-sedimentary succession composed of a very consistent, shallow marine duplex of sandstone-shale to chemogenic metasedimentary and metavolcanic rocks that have undergone multiple phases of deformation and metamorphism. The time of deposition of the Bushmanland Group is constrained between the age of the youngest detrital zircon (~1.64 Ga) and the onset of the regionally extensive Kibaran Orogeny at ~1.2 Ga. Metamorphic overgrowths and rims on detrital zircons record two distinct events, the ~1.21 to ~1.18 Ga Kibaran Orogeny, characterised by extensive granitic magmatism, peak D2 deformation and peak upper amphibolite facies grade M2 metamorphism, and the more ubiquitous ~1.04 to ~1.01 Ga Namaquan Orogeny characterised by weaker M3 metamorphism Locally the farms are underlain by Quaternary sediments that partially cover the Bushmanland Group supracrustals and these in turn overly a gneissic basement with some intrusions. The Bushmanland Group is divided into two subgroups; Aggeneys and Nab Subgroup. The variations in the two subgroups are shown in Table 2 below. It is accepted that there are lateral facies chances between the two subgroups, the Gams and Kouboom. Formations are facies equivalents of Hotson Formation and the Wortel Formation is the equivalent of the Witputs Formation.
McClung (2006) subdivided the Bushmanland Group into two subgroups and thirteen formations.The base of the Bushmanland Group (Wortel Subgroup) comprises a thin (250-350 m thick) sequence of interbedded upward-coarsening psammo-pelitic schists and mature quartzite (i.e. meta-orthoquartzites) of the Namies Schist Fm., Pella Quartzite Fm., Bloemhoek Fm. and laterally equivalent Kangnas Fm. In contrast, the metasedimentary rocks of the unconformably overlying Kouboom Subgroup can be separated into facies terrains divided by the Pofadder-Tantalite Valley Shear Zone (PTV Shear Zone). West of the PTV Shear Zone the Kouboom Subgroup is characterized by a thin (205-225 m thick) succession of interbedded mature quartzites and pelitic schists. East of PTV Shear Zone the Kouboom Subgroup encompasses a thick (~1250 m thick) succession of calc-silicate rocks hosted by biotite to calc-silicate-rich schists and metagreywackes. The Koeris Fm., a variably thick (0-650 m) succession of psammitic schists, meta-conglomerates and ortho-amphibolites unconformably overlies the Kouboom Subgroup.

The Aggeneys Terrain is cross-cut by numerous faults allowing for subdivision of the terrain into smaller domains. The terrain was shortened by the southward directed contractional deformation of the Namaquan Orogeny that resulted in the formation of numerous east-west trending thrusts and shear zones. The Namaquan Orogeny was then followed by the localized exhumation of the Basal Gneiss Complex that resulted in the formation of north-south trending extensional faults.

Despite being next to the Vedanta Black Mountain, access to the farm is very poor. The current road is only navigable by a 4×4 vehicle. However, this will be a small issue as the roads and access can easily be upgraded due to the short distance to Aggeneys which has sufficient infrastructure to support a mining operation.
Power lines will need to be constructed from the Aggeneys substation to Koeris 54 for approximately 15 km.
The nearest railway line is at Aggeneys, there may be no need to build a newline to join the Aggeneys line, as the ore or concentrates can be moved by road.
Access roads will need to be constructed to the N14 and Aggeneys Town.
For mining purpose water may be pumped through pipelines from the Pella pump station to Koeris 54, which is approximately 60KM.
