Apollo has discovered a new style of semi-massive sulphide mineralisation which could drastically enhance the prospectivity of its province-scale Kroussou Project in Gabon.

Semi-massive and disseminated style zinc and lead sulphides were observed visually from near surface intercepts in multiple drill holes completed at Target Prospect 13 (Niambokamba), which is one of 18 target prospects identified at the project.

The mineralisation was observed in five drill holes over more than 200m of strike with downhole thickness ranging from 2m to 18m and commencing from 3m below surface. It remains open to the north and south.

Importantly for Apollo Minerals (ASX:AON), the discovery indicates the presence of a shear-hosted system and possible primary high-grade feeder structures which managing director Neil Inwood described as a potential game changer.

“We interpret these new mineralised zones to represent primary feeder-structures for high grade zinc and lead. We expect that the assays, when received, will indicate a step change in the target grade-profile at Kroussou,” he added.

“The discovery complements the recent airborne electromagnetic survey and enables our technical team to generate comprehensive exploration targets across the province scale Kroussou project.”

Assays from drilling at the Niambokamba prospect – located 7km north of the Dikaki prospect which has also seen shallow, high-grade zinc-lead hits – are pending.

Niambokamba prospect drilling

The company recently completed the drilling of 24 diamond drill holes totalling 1,091m on three discrete areas (or lobes) at Niambokamba to test the channels for base metal mineralisation.

Semi-massive and disseminated sulphides were identified in multiple holes in the NK-NW area with a close association with nearby barite veining and shearing.

Targeted drilling in this area was based upon a 500m wide by 1.3km long soil geochemical anomaly that is adjacent to a historical drill hole which returned a 3m intersection grading 4.8% lead+zinc from a down-hole depth of 45m.

Apollo expects targeting of this new style of mineralisation to be complemented by the recently completed airborne electromagnetic survey and the associated magnetic data, both of which are currently being processed.
