Mako Gold Ltd (ASX:MKG) has completed reverse circulation (RC) drilling on the regional Gogbala prospect at Napié Gold Project in Côte d’Ivoire, with the high-grade results confirming the potential of a major gold system.
The drilling was designed to test along the more than 23-kilometre soil anomaly and coincident 30-kilometre-long structure that also hosts gold mineralisation 4 kilometres to the north of the main Tchaga Prospect.
Assays have been received for 30 of 53 holes from Gogbala indicating a similar style of mineralisation as observed at the main Tchaga Prospect.
Notable intersections from 10 of the 14 fences covering the southern portion of Gogbala include 6 metres at 4.97 g/t gold from 68 metres, including 1-metre at 12.3 g/t from 71 metres; 6 metres at 6.4 g/t from 58 metres, including 2 metres at 9.32 g/t from 58 metres; and 3 metres at 6.4 g/t from 58 metres, including 2 metres at 9.32 g/t from 58 metres.
Assays remain pending for an additional 20 wide-spaced shallow holes from the northern portion of the prospect.
“Potential to deliver significant growth”
Managing director Peter Ledwidge said: “We are highly encouraged by the first results of this phase of reconnaissance drilling at the Gogbala Prospect which returned several high-grade intercepts.
"Fourteen widely spaced drill fences were designed over 4 kilometres and results have been received for the southern portion of the Gogbala Prospect.
“It is highly encouraging that significant gold mineralisation was intersected on all fences drilled to date which warrants follow-up drilling.
“These initial results indicate that Gogbala has the potential to deliver significant growth to the Napié Project as we continue to drill this exciting prospect.”
Other results include 1-metre at 8.78 g/t gold from 13 metres, 6 metres at 2 g/t from 87 metres and 4 metres at 2.63 g/t from 11 metres.
Drilling ongoing with two rigs
Ledwidge continued: “The Tchaga East Prospect returned narrow, high-grade results from three widely spaced fences covering 800 metres of the 8-kilometre-long interpreted shear (parallel to the shear which hosts Tchaga and Gogbala mineralisation).
“Preliminary results indicate that the 8-kilometre-long shear hosts high-grade gold, and although drilling Tchaga and Gogbala is the highest priority, these Tchaga East results warrant follow-up drilling to test the full 8km shear.
“The company believes that Gogbala and Tchaga East have the potential to host high-grade deposits comparable to Tchaga, which is located 4 kilometres to the north and 2 kilometres to the west, respectively.
“Drilling is ongoing at Tchaga with two rigs drilling RC and DD.
“We look forward to providing updates on results as they come to hand.”
Shares are more than 7% higher to 10.5 cents.
Follow-up drilling is planned once the company receives assay results from all holes.
This will allow the company to prioritise targets on the most prospective mineralised zones in order to define and extend gold mineralisation.
Tchaga prospect drilling
Drilling is ongoing at the Tchaga Prospect. Now that drilling is completed on the Gogbala prospect, the second drill has moved to Tchaga to accelerate drilling on the extensional and infill maiden drilling program.
One drill is used for RC drilling and the other is drilling deeper DD holes, to outline a maiden resource to 150 metres vertical depth.
Korhogo Project soil geochem
The soil geochemical program on the Korhogo Project is rapidly progressing with four crews on the ground as the project has been strategically selected by Mako with its greenstone-granite contact along a regional fault.
Regional faults provide the 'plumbing' for gold-bearing fluids.
It is notable that splays are evident in the regional faults on both permits.
The soil sampling grids on the permits cover two splays, which Mako consider to be high-priority exploration targets.
A high-resolution airborne geophysical survey is scheduled to begin shortly and a maiden drilling program is planned following the airborne geophysical survey and after receipt of the soil sampling results.
