About Giro


Amani Gold holds a 55.25% interest in two exploitation permits which cover 497km2 of prospective ground in the Haut-Uele Province, north-east Democratic Republic of Congo.

The tenements are less than 30km west of Randgold Resources / AngloGold Ashanti’s multi-million ounce Kibali Gold deposits as shown in Figure 1. Kibali produced 642,720 ounces of gold in 2015 and is targeting production of 610,000 ounces for 2016, confirming a favourable mining environment in the region.

Historically, the Belgians mined alluvial and primary gold from a number of prospects within a 35km, NW trending, highly prospective structural corridor. Exploration was primarily focused on early stage and infill resource drilling on the multi-million ounce potential Kebigada Prospect and scout shallow RC drilling on the newly discovered, high grade Douze Match Prospect with an associated 6.5km gold in soil anomaly. Soil samples were collected over the entire 35km corridor where several additional targets were generated for drill testing.

Mineralisation at Kebigada has been defined over 1,500m by ~350m and is from surface to depths greater than 250m. Amani is expecting to release an inferred maiden mineral resource estimate in early 2017.Both the Kibali and Giro projects occur within the Kilo-Moto Belt, one of the world’s principal greenstone belts which also host AngloGold Ashanti’s deposits to the east and Loncore and Kilogold deposits to the south. Approximately 50Moz of gold has been discovered in the Tanzanian portion of the belt since 1994.

The Giro 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. At least three additional extensive alluvial workings occur within the project area, confirming the potential for new discovery of primary mineralised targets.

The Giro Project area had not been explored for more than 50 years (since the Belgian colonial era) with no modern exploration up to December 2013 when Panex conducted a 57-hole 2,888m reverse circulation (RC) drilling programme at the Giro Prospect. Drilling confirmed mineralisation occurs within two separate structures, the Kebigada Shear Zone and the Giro Vein.

To date Amani’s exploration focus has been on drilling, geochemical sampling and geophysics on priority target areas on both tenements. Diamond drilling programmes were completed at Kebigada (1,221m), Giro vein (310m), Peteku (100m), Adoku (579m) and Mangote (633m) and all results have been reported. Soil sampling defined a >200ppb gold-in-soil anomaly over 2,000m x 900m at the Kebigada anomaly, Amani’s most advanced prospect, where best results from Amani’s RC and diamond drilling programme include:

  • 97m at 2.56g/t Au from surface
  • 47m at 4.13g/t Au from 25m, including 29m at 5.93g/t Au from 25m
  • 33m at 1.59g/t Au from surface and 56m at 2.39g/t Au from 64m including 9m at 5.20g/t Au from 66m
  • 23.5m at 3.07g/t Au from 0.5m, including 13.6m at 4.73g/t Au from 4.4m
  • 21.0m at 6.06g/t Au from 0m and 69.6m at 1.67g/t Au including 39m at 2.3g/t Au from 94.9m

Gold mineralisation related to the Kebigada Shear Zone has been defined over 1,500m strike length and is interpreted to have two distinct orientations, namely a strong NNW orientation as observed in the IP gradient array survey and a W-E to WNW-ESE orientation interpreted from measurements of pyrite and chalcopyrite laminae in the drill core and associated gold grade. Most holes were drilled towards the NE as shown in Figure 2, oblique to the high grade W-E orientation.

Drilling at the Kebigada Shear Zone confirmed significant mineralisation from surface down to 150m below surface (Figure 3). Results from the recently completed campaign clearly show that gold mineralisation is open in all directions from surface down to depths exceeding 250m vertical metres.

The Company has also reported highly significant mineralisation from first pass drilling at its Douze Match target area at Giro (Figure 4). The initial shallow scout RC drilling programme was designed to test approximately 1km of the soil anomaly which extends over 6km x 2.5km at Douze Match.

Best results from the first 10 RC drill holes included:

  • 2m at 196g/t Au from 12m and 15m at 255.6g/t Au from 15m, including 3m at 1260g/t Au from 15m, including 3m at 14.3g/t Au from 21m
  • 33m at 6.1g/t Au from surface including 3m at 34.7g/t Au in laterite
  • 12m at 21.2g/t Au from 3m
  • 7m at 5.2g/t Au from 30m in granites in contact shear zone

Further drilling will continue to define the extent of the mineralisation and also target greater depths down to 100m.

Amani has completed soil sampling and mapping across the entire 35km NW trending prospective structural corridor which transgresses both licences on the Giro Project and has completed a second phase of drilling at Douze Match including the Siona target. Further drilling will follow up results at Douze Match, Adoku and Mangote in 2017.
