THE DRILL SERGEANT: AVZ Minerals (ASX: AVZ) reported results from Mineral Resource drilling undertaken at the company’s Manono lithium and tin project in the Democratic Republic of Congo.
AVZ Minerals received the results from the final two of six reconnaissance drill holes it recently drilled at the Carriere de l’Este prospect.
The company said the results confirmed further widespread, high-grade spodumene lithium mineralisation, including 68 metres at 2 per cent lithium oxide (Li2O) and 858ppm tine in hole CD18DD006.
Ninety samples returned values greater than 2 per cent including five individual samples grading greater than 4 per cent Li2O with the highest value being from hole CD18DD006 from 181 to 182 metres downhole grading 4.65 per cent Li2O.
AVZ interpreted the results from the latest drill holes to demonstrate grade continuity both down-dip and along strike at Carriere de l’Este with both holes starting in soil cover and confirming the presence of a ‘blind’ pegmatite in previously unknown strike extents of the main deposit.
“These last two holes drilled at Carriere de l’Este are of the same lithium grade tenor and intersection widths as those reported on previously – (19th February 2019),” AVZ Minerals managing director Nigel Ferguson said in the company’s announcement to the Australian Securities Exchange.
“Both holes five and six have drilled through high-grade zones averaging over two per cent lithium oxide, mineralisation which was also seen on holes spaced 200 metres along strike.
“Hole five for example generated 56 by one metre assays greater than two per cent lithium oxide with a maximum value in one sample of 3.97 per cent from 166 to 167 metres deep.
Hole six was comparable with 97 samples returning values greater than two per cent including five individual samples grading greater than four per cent lithium oxide which equates to each of the five samples containing in excess of 50 per cent spodumene.
“The highest value from hole six was from 181 to 182 metres downhole and reported 4.65 per cent lithium oxide.
“Carriere de l’Este is unlike Roche Dure in that it has higher-grade zones within well mineralised pegmatite suggesting a more classical zonation model for this large pegmatite.
“Depending on future drilling, this may open up possibilities for high grade blending with Roche Dure mineralisation to shorten pay back periods and is definitely worth considering as we move through the mining study phase currently underway.”
