Mako Gold Limited (ASX:MKG) believes its Tchaga prospect in Cote d’Ivoire has the makings of a significant gold discovery after revealing a new shallow, high-grade gold zone, with assays of up to 143 g/t gold.
The assay results were received for a further four reverse circulation (RC) holes from the ongoing 10,000-metre RC and diamond drill program on its 224 square kilometres Napié Project in Côte d’Ivoire.
Reported holes were drilled in the revised southeast drilling orientation following the outcome of recent mineralisation modelling, validating the recent change in drilling orientation and confirming multiple new high priority targets.
Drilling is ongoing to extend the strike length of the new high-grade zone.
A second drill rig is scheduled to commence drilling in early December to test highly prospective regional prospects at Gogbala, Tchaga East and Tchaga North.
"Makings of significant discovery"
Mako managing director Peter Ledwidge said: “Following our recent technical reviews and subsequent change in drilling direction, we are highly encouraged by the results returned from drilling in this zone where we had previously received assays of 13 metres at 20.82 g/t gold and 18 metres at 3.25 g/t gold.
“Much of our previous West to East drilling in this zone would have only grazed the mineralisation or missed it altogether.
“Our recent modelling has indicated multiple highly prospective areas that remain undrilled, therefore we will be prioritising drilling in the short-term to drill along strike and extend the high-grade zone.
“Drilling is ongoing at the Tchaga prospect and we look forward to providing updates on further RC and DD drill results in the near future.
“These new results provide the company with confidence as we move towards targeting a maiden resource on the Tchaga prospect.
“When you consider that we have multiple prospects to the North, South and East with previously reported high gold-bearing intercepts, we consider that the Tchaga prospect has the makings of a significant gold discovery.”
The drill program follows up on previous high-grade intercepts in the mineralised zone which include 13 metres at 20.82 g/t gold and 18 metres at 3.25 g/t gold.
Significant new results returned from the high-grade zone include:
- 9 metres at 1.17 g/t gold from 13 metres;
- 5 metres at 2.16 g/t from 27 metres;
- 9 metres at 22.73 g/t from 36 metres, including 2 metres at 92.95 g/t from 36 metres and including 1-metre at 143.6 g/t;
- Averages 32 metres at 7.1 g/t from 13 metres to 45 metres.
- 15 metres at 3.59 g/t from 16 metres, including 1-metre at 31.66 g/t gold from 26 metres; and
- 4 metres at 14.26 g/t from 33 metres, including 1-metre at 51.11 g/t from 33 metres.
The mineralised zone remains open in all directions.
Further drilling planned
Further drilling is planned in this area to maximise the size potential of the high-grade mineralised zone to form part of a maiden JORC resource in the first quarter of 2021.
Within the Tchaga prospect, gold mineralisation is associated with later, northeast-southwest trending, cross-cutting structures, producing the stacked lenses.
The stacked lenses remain open in all directions and significant strike length remains to be drill tested.
Tchaga prospect, along with other prospects identified to date on the Napié Permit, is associated with more than 40 parts per billion gold soil anomaly coincident with a more than 30 kilometres-long shear zone, thought to be a major control for gold mineralisation.
The potential for outlining significant gold mineralisation exists on all prospects within the Napié Permit.
Upcoming programs on various prospects, include adding a second drill rig in early December to test regional targets.
