West African gold explorer Tietto Minerals (ASX: TIE) has reported “exceptional” high‐grade gold intersections at the Abujar‐Gludehi (AG) deposit within its Abujar gold project in the Côte d’Ivoire region of West Africa.
The first batch of assays for three diamond holes confirmed strike continuity and depth extension of the near-surface gold mineralisation, with best result being an intercept of 4m at 100.73 grams per tonne gold from 76m, including 1m at 394.36g/t gold from 77m.
Other results were 7m at 4.68g/t gold from 87m, including 1m at 13.16g/t gold from 87m, 2m at 8.78g/t gold from 92m and 1m at 13.2g/t gold from 93m.
The results are from an ongoing 30,000m extensional and infill drilling program focused on growing Abujar’s global 1.7 million ounce gold resource base.
The program specifically aims to extend the high‐grade core at AG which currently hosts 1.06Moz gold at 2.1g/t.
Managing director Dr Caigen Wang said the results may help deliver a major resource increase for Abujar.
“These latest diamond holes confirm the presence of high to exceptionally high‐grade gold mineralisation at shallow depths on the northern half of AG where we have already defined a [considerable] resource,” he said.
“We are very confident the intercept of 394g/t gold will add further shallow, high-grade ounces to our resource update.”
Following completion of the current holes, Tietto’s rigs will move to another part of the project to test the strike extension of gold mineralisation exposed by extensive surface artisanal workings.
Dr Wang said the company is on track to deliver updates to current JORC mineral resource estimates for the AG and APG (Abujar‐Pischon‐Golikro) deposits before year end.
Drill rig ownership
The Abujar gold project is approximately 3km from the major regional city of Daloa, in central western Côte D’Ivoire.
It comprises the contiguous Middle, South and North tenements over a total land area of 1,114sq km, of which less than 10% has been explored.
Earlier this week, Tietto announced it would accelerate its current exploration program following the acquisition of a third diamond drill rig.
The strategy of owning and operating its own drill rigs provides Tietto with substantial cost savings including a reduction of more than 70% on per metre drilling costs relative to industry averages.
It also increases the amount of drilling the company is able to undertake relative to other companies for a given expenditure.
At mid-morning, shares in Tietto were trading 3.33% higher at $0.155.
