Emerging gold producer Tietto Minerals (ASX: TIE) has advanced the de-risking its 3.35 million ounce Abujar gold project in Cote d’Ivoire as infill drilling sees multiple high-grade hits.
The drilling’s aim is to convert a portion of the indicated resources — which stands at 35 million tonnes at 1.5 gram per tonne, for a contained 1.65 million ounces — to the measured category.
The expected measured resource will underpin the first two years of mining at Abujar.
Assays have been received for 24 holes (a total of 3,843m) from a planned 30,000m program.
The latest results are led by 3m at 35.65g/t (including 1m at 98.03g/t).
Not yet drilled into ‘meat’ of the deposit
Other cores assayed a 7m at 12.48g/t, 19m at 2.33g/t, 17m at 1.68g/t and 7m at 3.66g/t, with all those cores containing higher grade intervals.
Managing director Caigen Wang says that assays for another 63 holes are still pending, with 15,000m of drilling completed so far and the other half of the program still to be finished.
“Our infill drilling program at Abujar has delivered more high-grade gold intercepts that will further de-risk open pit mining at Abujar.
“We have not yet drilled down into the meat of the deposit so we expect to see more high grades as results from these holes start to come in from the lab,” Dr Wang added.
The remainder of the drilling program is expected to finished early in the December quarter.
Planned 100,000m drilling in 2021
Meanwhile, the company says work is progressing on the definitive feasibility study with key findings expected by the end of this month.
Mine engineers have incorporated the updated resource model released in July into their mine optimisation planning.
The next resource update should be completed in the December quarter.
Tietto says it is well funded with about $45 million cash.
All up, Tietto is targeting 100,000m of diamond drilling in calendar 2021 using its six company-owned diamond rigs, at a cost of US$35 per metre of drilling.
The company has previously announced the purchase of a SAG mill.
Tietto continues to negotiate with the Invorian Government on the Abugar mining convention, the final regulatory step in the approvals process.
