Significant high-grade gold assays from Amani’s Kebigada deposit

Amani Gold Limited (ASX:ANL) today announced that it has successfully targeted deeper high-grade gold mineralisation at Kebigada gold deposit at the Giro Gold Project.

The Giro Gold Project lies within the Kilo-Moto Belt of the DRC, a significant under-explored greenstone belt which hosts Randgold Resources’ 16 million-ounce Kibali group of deposits within 35km of Giro.

Drillhole GRDD034 in the Phase One diamond core drilling program at Kebigada successfully targeted deeper high-grade sulphide associated gold mineralisation within the central core of Kebigada deposit.

GRDD034 returned the following significant high-grade gold assay results — the deepest yet at Kebigada:

  • 58m @ 1.61g/t Au from 204m, including 11m @ 2.75g/t Au from 208m and 10m @ 3.26g/t Au from 228m
  • 23.65m @ 1.183g/t Au from 299m, including 1m @ 10.5g/t Au from 303m and 1m @ 3.72g/t Au from 308m; and
  • 21m @ 0.76g/t Au from 335m, including 4m @ 1.48g/t Au from 335m and 1m @ 2.02g/t Au from 355m.

Drillhole GRDD034 (EoH 414.9m) was collared adjacent to section L750N and drilled with an inclination of 70° and an azimuth of 43° and targeted deeper gold mineralisation previously delineated in hole GRDD025.

Analysis of cut core of holes GRDD025 and GRDD034 indicates lithological continuity and style of mineralization. Drillhole GRDD034 intersected sulphide mineralisation in the form of dissemination, quartz/pyrite and pyrite veins, stringers and distinct pyrite laminas all of which may be associated with gold mineralisation.

The Giro Gold Project area is underlain by highly prospective volcano-sedimentary lithologies in a similar structural and lithological setting as the Kibali gold deposits. Both primary and alluvial gold was mined from two main areas, the Giro and Tora areas, during Belgian rule and today these areas are mined extensively by artisanal miners.

GRDD034 intersected broad intervals of pyrite mineralization from 204.00m to 263.50m (59.5m interval containing 2-3% pyrite), from 286.9m to 322.5m (35.6m interval containing 1% pyrite) and from 334.0m to 373.0m (39.0m interval containing 1-2% pyrite). These sulphide intervals have correlated well with the returned gold assays.

Phase One drillhole GRDD035 was also completed, along with GRDD034, and has been analysed and core samples sent to SGS Mwanza laboratory in Tanzania. These assay results are expected in mid-November.

If they show that significant gold mineralisation has been intersected in GRDD035 too, additional Phase Two drilling may comprise a further four core holes, each 500m in length.

Amani’s Technical Director, Mr Grant Thomas commented: “These assay results from GRDD034 are highly significant as it indicates we have successfully targeted deeper high-grade gold mineralisation at Kebigada, the deepest yet.

“If the results are as good in the much deeper Phase One drillhole, GRDD035 then we will need to consider implementing an additional phase of drilling asap. An upgrade of the Kebigada resource estimate also seems warranted”.

The current gold resource estimate outlined at Kebigada, Giro Gold Project is 45.62Mt @ 1.46g/t gold for 2.14Moz gold at a cut-off grade of 0.9g/t gold.
