So far, the gold explorer has seen assays from 15 reverse circulation (RC) holes at the Gogbala prospect and six diamond drill holes from the Tchaga prospect, both of which are located on the same 23-kilometre-plus soil anomaly and near the 30-kilometre Napié fault.
Initial results indicate that Gogbala has the potential to host similar stacked gold lodes to those identified at Tchaga, meaning it could play host a major gold deposit.
The phase one drill program at the Gogbala prospect has run its course, so Mako intends to continue drilling in Tchaga’s south as part of its broader 35,000-metre drilling campaign at the Napié asset.
Results to date “encouraging”
Mako Gold managing director Peter Ledwidge said: “The Gogbala prospect is displaying similar structural and mineralisation characteristics as the Tchaga prospect.
“We are very encouraged by the results achieved to date on Gogbala with limited wide-spaced drilling."
He said: “Although it is early days it appears that Gogbala is likely to have the same stacked lodes which are prominent at Tchaga.
“Our strategy at Gogbala is to focus on areas which return high-grade assays and to drill outwards from these zones to delineate stacked lodes with the aim of increasing the potential mineral inventory.
“In the short term, we will alternate drilling between Gogbala and Tchaga. We also have plans to drill the Tchaga North and Komboro prospects.
“We look forward to providing results from Tchaga and Gogbala as they come to hand.”
Recently, Mako embarked on a 10,000-metre RC drilling campaign at Gogbala, aiming to better target the prospect’s high-grade areas and delineate its stacked lodes.
Promisingly, 12 of the 15 holes intersected strong mineralisation, including:
- 7 metres at 6.16 g/t gold from 6 metres, including 3 metres at 10.61 g/t from 6 metres;
- 8 metres at 2.87 g/t from 49 metres, including 1-metre at 11.13 g/t from 53 metres;
- 8 metres at 1.15 g/t from 51 metres; and
- 5 metres at 1.06 g/t from 59 metres.
In particular, mineralised intervals such as 7 metres at 6.16 g/t gold, show the potential for Gogbala to host high-grade mineralisation similar to Tchaga.
With the first drilling phase done and dusted and the initial RC assays live, Mako has also been able to pinpoint similarities between the structurally controlled gold deposition at the Gogbala and Tchaga prospects.
Namely, the 'pinch and swell' characteristic of mineralisation observed at Tchaga is also present at Gogbala, which lends itself well to follow-up drilling along strike and down dip.
Ultimately, Mako believes that Gogbala has the potential to host similar stacked gold lodes as those identified on the Tchaga Prospect, meaning it has the potential to host a significant gold deposit.
Meanwhile, over that the Tchaga prospect, the gold explorer has sighted results from six diamond drill holes, all of which hit significant mineralisation.
Several holes recorded multiple gold intersections in a program designed to test mineralisation along strike and at depth.
Some of the best results include:
- 2 metres at 6 g/t gold from 193 metres;
- 3 metres at 2.79 g/t from 20 metres;
- 3.2 metres at 1.25 g/t from 170 metres;
- 3 metres at 2.28 g/t from 160 metres;
- 3.8 metres at 1.22 g/t from 196 metres
- 2.4 metres at 1.80 g/t from 126 metres; and
- 3.8 metres at 1.23 g/t from 152 metres.
Looking ahead, further drilling at Tchaga will continue testing the large soil anomaly and extending zones of high gold mineralisation along strike and at depth.
Now the phase one drilling program at Gogbala is complete, the drill rig has returned to Tchaga South for further exploration as part of the broader 35,000-metre campaign.
Results-wise, assays are pending for 14 RC holes in the phase one program.
Interestingly, Gogbala is only 5 kilometres from the Tchaga prospect, with these promising results indicating it could substantially add to the upcoming maiden mineral resource estimate.
