The Naton project is located 125km WSW of the capital Ouagadougou. The tenement lies within the Boromo greenstone belt which is principally composed of Paleoproterozoic Birimian terrain within the West African Man Craton. This belt also hosts the Poura gold deposit (1 to 2 Moz), situated approximately 50km to the south-southwest of the area, as well as numerous gold occurrences. The Perkoa Volcanogenic Massive Sulphide deposit is located about 35km to the north of the area. IGL targeted this area based on extensive artisanal gold workings and previous exploration that had identified multiple hard rock gold targets, that had not been sufficiently tested.
Naton Project History
Canadian junior exploration company, Carlin Resource Corporation (“CRC”) and Sahel Gold Mines (“SGM”), on behalf of a private Canadian company, explored the tenement from 1996 to 2014. During this time, soil sampling, trenching and mapping of old gold workings was completed. CRC tested 7 targets with 40 RC holes for a total of 2,836m of drilling. SGM focussed in the far northwest of the area at the well-known Kwademen Prospect, which has a number of ancient workings. SGM completed soil sampling, trenching, Rotary Air Blast (RAB) drilling (1,005m in 23 holes) and diamond drilling (539m in 5 holes). Soil sampling has been carried out over approximately 30% of the project tenement. Samples have been collected on a nominal 200m x 200m grid with infill sampling to 100m by 100m in places. There appears to have been no significant work undertaken since 2014 other than IGL’s due diligence activities. Source: GA CPR 2017
Although the Naton project is an early stage exploration project, it does present strong indicators of mineralisation. All known orogenic gold deposits in Burkina Faso are hosted in Birimian Greenstones and approximately 75% of the tenement consists of such gelogy as shown in Figure 4. The geology of the tenement is a mix of volcano-sedimentary rocks composed of amphibolised mafics in the west and east, volcano-sedimentary schist in the southwest, schist and quartzite in the northwest, and a gabbro on the southern boundary. All are viable exploration targets.
Naton – Extensive gold soil anomaly
- Soil sampling, mapping, trenching, magnetics and IP is planned for prospective areas that have been identified
- Early drill testing anticipated
Interesting results thus far include:
- Kwademen Prospect — Multiple shear zones and soil anomalies over 1,000m strike length, including one previous RAB hole with 13m @ 22.1 g/t Au
- Bido Vein — An intercept of 1.5m @ 21 g/t Au at the base of the hole (25.5m)
- Kaga Vein — A 600m long structure with 7.5m @ 1.2 g/t Au from 22.5m to 30m (EOH)
