The concession area is represented by Precambrian rocks that form part of the extensive Neoproterozoic orogenic belt referred to as the Arabian - Nubian Shield. The Hodine concession displays a wide range of rock units that incorporate tectonically interleaved remnants of oceanic and island-arc material and high-metamorphic-grade gneisses associated with orogenesis that occurred shortly after terrain accretion. Late-stage intermediate - felsic igneous intrusions punctuate the ophiolite landscape.
Outcrop exposure across the Hodine Concession area is generally very good with only a modest percentage of ground (<20%) being covered in sand/and or wadi alluvial material.

The Hutite prospect is situated in a 15 km strike length, steeply dipping, north-west trending structural corridor that has been subject to significant late-stage alteration and quartz vein development. The structural corridor delineates the deformed western margin of a regional NW-trending belt of ultramafic rocks and to the south and the sheared margin of a large (meta-) gabbro-diorite intrusive complex to the east. This important metamorphic domain boundary between the high-grade gneisses east of Hutite and the lower-grade island-arc and ultramafic rocks has previously been interpreted as a regional extensional detachment that formed during development of a metamorphic core complex in this region. It is highly probable that the Hutite Structural Corridor has at least partially re-activated along sections of this key earlier-formed domain boundary.
