Earlier this month the company increased the mineral resource by 146% at the Abujar Gold Project in central west Cote d’lvoire in West Africa.
To date, the company has defined mineral resources over a small portion of about 6.9 kilometres of a 70-kilometre mineralised corridor across three project tenements.
Tietto aims to complete more than 20,000 metres of diamond drilling using company-owned rigs in 2019 targeting a further resource upgrade in late 2019.
To accelerate gold exploration operations the company deployed a second, larger diamond drill rig at the Abujar-Gludehi deposit, which is capable of drilling to 800 metres depth.
The company has also lodged two applications for exploration permits in northern Cote D’lvoire where several major operating gold mines and new gold discoveries are hosted.
