This edition of Mining Review Africa is definitely worth celebrating! It focuses on Central Africa and the Democratic Republic of Congo (DRC) in particular, which despite its negative perception is quickly becoming one of the most buoyant mining countries in Africa.

Orezone further expands higher grade zone at Bomboré

TSXV-listed gold junior Orezone Gold Corporation has announced positive results from an on-going drill programme at its Bomboré gold project in Burkina Faso.

Burkina Faso - The programme is currently focused on expanding the P17S sulphide zone that is hosted in a shallowly plunging granodiorite intrusive situated 2 km south of the Bomboré mining permit.

The initial resources at P17S were defined by shallow drilling to a depth of 60 m. The results from a 62-hole drill programme completed in 2016 extended the deposit to a depth of 100 m. Drilling resumed in mid-February with the completion of an additional 40 reverse circulation (RC) and core holes.

Highlights include 21 m at 2 g/t and 12.2 m at 3.6 g/t.

The further step-out holes with pending assay results have intersected mineralised granodiorite to a vertical depth of 150 m and indicate a down-plunge continuity of the zone to over 350 m.  The positive drill results from these additional 102 holes will result in an expansion of the initial resource.

Furthermore, the deposit remains open at depth and to the north where the drilling programme continues.

“These results continue to demonstrate the significant exploration potential at Bomboré,” states Ron Little, CEO for Orezone Gold Corp.

“The expansion of the higher grade sulphide zones at Bomboré, such as P17S with an average grade of +2 g/t, will improve the economics (at current gold prices) of a potential Phase II sulphide plant expansion by mining and processing this higher grade material in the initial years to ensure a faster pay back of the expansion capital.”

“Further studies of a Bomboré Phase II sulphide expansion, will focus only on a portion of the total Bomboré resources, which is the fresh rock (sulphide) measured and indicated resource of 71 Mt at 0.97 g/t for 2.2 Moz as well any expansion thereof as a result the current drill programme. The well-studied 2.2 Moz sulphide resource and the P17S zone are both amenable to standard milling and carbon in leach (CIL) recovery processes.”

The company has completed more than 8 000 m of auger, RC and core drilling during the first quarter and is planning an additional 15 000 m of drilling in Q2, 2017.

All assays were performed using a 1kg bottle roll technique (identical to the other Bomboré samples); leach residue assays are pending for 19 holes, including the last nine core holes drilled at P17S.
