The ore bodies at New Luika comprise high grade (>6g/t Au), medium grade (3 – 6 g/t Au) and low grade (1 – 3 g/t Au) to average 3.9g/t Au.The regional geology is characterised by deformed, folded, sheared and metamorphosed paleoproterozoic rocks with major fold axes trending east southeast to west northwest. The following main lithological units occur in the region:Ilunga Granite FormationThe Ilunga Granite is located in the northern portion of the Lupa Goldfield and is mostly comprised of a medium to coarse grained leucogranite (aplogranite). Biotite and muscovite are commonly associated secondary minerals.Saza Granite Formation The Saza Granite is located in the central portion of the Lupa Goldfield and consists of numerous rock types including hornblende rich granites and hornblende-biotite rich granodiorites.Gneiss FormationThe Gneiss Formation, the main ore bearing host, is the dominant rock unit within the Lupa Goldfield. The Gneiss Formation has been subjected to at least three granitic intrusive events that have given rise to a variety of rock types such as felsitic gneiss, biotite and hornblende granite gneiss, leucocratic granular gneiss. Diorite, granodiorite and granite rocks are evident within the Gneiss Formation.Mineralised quartz veined targets are hosted within brittle-ductile to ductile deformational features of variable orientation.Underlain by a complex association of high grade metamorphic- and intrusive lithologies, commonly intruded by dykes of variable composition. Modally, granodioritic and granitic lithologies are most commonly encountered. These granodiorites and granites have been interpreted as late orogenic intrusive phases associated with gold mineralisation in the area. Subordinate diorite, porphyroblastic hornblende gabbro, quartzo-feldspathic felsite and migmatite are also regularly observed. Dyke intrusives include dolerite, pegmatite and common aplite and alaskite, seemingly randomly crosscutting major lithologies, and therefore regarded as younger than the country rock.
