The Kamsongo Gold Prospect is located in eastern Burkina Faso, approximately 240km south-east of Ouagadougou (figure 1).
No surface gold occurrences are known from the Kamsongo area. The Kamsongo Propsect was identified by Orbis through a regional soil sampling program targeting geophysical/stratigraphic gold targets.
The Kamsongo Prospect is defined by a large-scale low-order (+10ppb Au) gold-in-soil anomaly that extends over a 14km strike length. The broader soil anomaly includes several discrete zones of +20ppb Au anomalism – referred to as the South, Central and North Zone targets (figure 2).
The Kamsongo soil anomalies are in-part coincident with an elongate and fault disrupted package of sheared greenstone rocks developed along the north-west margin of the Nabanga Intrusive. Although the Kamsongo anomaly is located in proximity to Orbis’s high grade Nabanga gold deposit (located 10km to the east) it is thought to represent a separate gold system.
Reconnaissance RAB and RC drilling of the 5km long North Zone anomaly by Orbis intersected near-surface +0.5g/t gold mineralisation across all three of the wide-spaced sections drilled. Best intersections included 4m @ 1.90g/t Au (from 7m), 3m @ 0.82g/t Au (from 6m), and 4m @ 1.46g/t Au (from 8m) (figure 3).
The initial drilling indicates that gold mineralisation occurs in proximity to the targeted granodiorite-greenstone contacts – a geological setting recognised to host gold mineralisation in numerous instances across Burkina Faso and the Birimian Gold Province.
On a regional scale, Orbis has interpreted (through high resolution geophysics) a significant 15km strike extension to the Kamsongo target stratigraphy/structures to the north-east of the current prospect area. This area has never been explored (figure 2).
Orbis proposes additional soil sampling and further drilling across the broader Kamsongo Prospect area.
