The first five (5) reverse circulation (“RC”) holes drilled at the Kobada Project were designed to confirm the extent of gold mineralization from historic drilling in an area that had been drilled parallel to trend and to generate a better understanding of the controls on mineralization, lithological characteristics and structures of the Kobada Project deposit so as to guide next phases of drilling.
- 1.60 grams per tonne gold (g/t Au) over 19 metres, from 86.0m, including 3.24 g/t Au over 6.0m within the Kobada Shear Zone in hole RC2.
- 1.80 grams per tonne gold (g/t Au) over 18 metres from 114.0m, including 18 g/t Au over 1.0m, within the Kobada Shear Zone in hole RC3.
- DRA Global (Toronto) have been engaged to complete a gap analysis on the historical feasibility study.
- Kobada Est exploration license adjacent to Kobada Mining License has been successfully renewed for a further three (3) years.
“Our welcome return to drilling at Kobada, Mali has delivered exciting initial results that continue to demonstrate shallow and wide zones of gold mineralization at the project,” noted Stephan Theron, President and CEO. “Our newly assembled technical team set out to demonstrate, in a short period of time, an increased confidence in the controls on gold mineralization, and expand new opportunities across our land package – we are successfully on that path with both our drilling results and adjacent exploration license renewal. We also look forward to additional diamond drill results and updating our shareholders as soon as possible.”
Mr. Theron also noted, “We are also excited to engage DRA Global (Toronto) to complete a gap analysis of the historical feasibility study with respect to current, updated industry standards. This work will enable us to rapidly move forward towards an updated feasibility study with greater effectiveness and efficiency.”
RC Drilling Results
691 metres in five (5) RC holes were completed in phase 1. Drilling focused on the northern limits of the historical and published National Instrument 43-101: Standards of Disclosure for Mineral Projects (NI 43-101) Mineral Resources in an area where previous drilling was orientated parallel to mineralization trend. (Figures 1, 2 and 3)

Gold at the Kobada Project is present in the laterite, saprolite and quartz veins that comprise the Koboda Project. There are also placer style deposits in the region, although these have largely been exploited by artisanal miners. Gold mineralisation was coeval with the hydrothermal events that introduced the regionally common quartz veins. The 20°NE structures are the only regional structures that have been identified on the property, the E-W and low angle features seem to be confined to the mineralised zone in-between discrete shear zones.
Mineralisation at the Kobada Project extends for a minimum strike of 4 km and is associated with narrow, irregular, high-angle quartz veins and with disseminated sulphides in the wall rock and vein selvages. Mineralisation occurs as free gold, sulphides present include arsenopyrite, pyrite and rare chalcopyrite. Visible gold is not common. Arsenopyrite (up to 5 mm) is localised near vein selvages and as fine-grained disseminated patches within the host rock. Pyrite occurs in finely disseminated patches within the host rocks and as euhedral crystals in the black shale, generally as trace to 3% by volume with up to 10% locally in the wall rock over centimetre scale intervals adjacent to quartz veins.
Veins have a milky white colour, are generally discordant with a thickness ranging from millimetric to sub metric. Mineralised veins are narrow, high-angle quartz veins, either cross-cutting another vein or the main fabric.

The Kobada Project is near-surface gold project that has a mineral resource base (all categories) of over 2.2Moz of gold. The project is located in Mali, Africa’s third largest gold producing nation, 125 km south southwest of its capital city, Bamako. Previous operators completed 1,108 holes and 126,335m of drilling on the property and completed 3 economic studies, the last one being a feasibility study released in February 2016. Although the economics were compelling, the new management of the project has decided to undertake internal scoping studies in order to gain a better understanding of the project with a goal to optimize the size of the envisioned mine and increase the confidence in the resource model. Salient features of the 2016 feasibility study included:
- Global resource of 2.2Moz in all categories
- Strong economic potential demonstrated in feasibility study
- LOM cash costs of US$557/Oz
- Initial capex of US$45.4M
- Post-tax NPV5% of US$86M and IRR of 43%
- Shallow mineralization with deep oxidation
- Ore is largely free-digging enabling mining to be conducted with significantly less blasting than other more conventional ore bodies
- Simple processing enables pre-concentration of ore resulting in lower processing costs
- Significant resource growth potential
- The 2.2Moz resource stretches over 4km within a larger 12km strike length that has not been properly tested
- An additional 30km of shear zone structures have been identified on the property and have yet to be explored (Figure 1)

Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of Mineral Resources will be converted to Mineral Reserves. Inferred Mineral Resources have a lower level of confidence that that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve.
