Wahgnion

Wahgnion is operated and 90% owned by Lilium Mining, with a 10% free carry in favour of the Government of Burkina Faso. Located in southwest Burkina Faso, Wahgnion is 510km southwest of the capital city Ouagadougou, within the Paleoproterozoic Birimian Senoufo Belt. The Senoufo Belt trends north-northeast and comprises mainly basaltic and andesitic volcanic rocks, lesser sedimentary rocks, and numerous gabbroic to granitic sub-volcanic plutons.

Mineralisation at Wahgnion is structurally controlled, predominantly of a lode-style gold type, associated with discrete structures. Higher gold grades are commonly associated with stylolitic laminated quartz veins or pyrite veinlets. Coarse-grained gold is found in fractures within pyrite veins or in quartz-carbonate vein selvages. The mineralisation is interpreted to have formed from the same mineralising system, with variations in style reflecting the difference in local lithological and structural settings.

The Wahgnion mine is a 3.0Mtpa – 3.2Mtpa carbon-in-leach operation, featuring multiple deposits feeding into a central mill and owner-operated conventional truck and shovel open-pit mining. First gold was poured in August 2019 with commercial production declared in 2019.

Wahgnion has a large Resource base available for conversion into Reserve and substantial potential for the discovery of new resources given that the existing mine sits within a very large exploration land package, itself within a globally important gold producing province.
