AVZ Minerals Limited (ASX: AVZ) has received further strong results from its Mineral Resource drilling of the Manono Lithium and Tin Project in the Democratic Republic of Congo.
Managing Director, Nigel Ferguson, said the assay results come from the first four of nine planned diamond drill holes at Roche Dure in previously undrilled areas beneath the historical pit which were inaccessible and under water during the earlier resource drilling programmes.
These drilling results, combined with the pit floor mapping, confirm the pit floor “wedge” is in fact made up of pegmatitic rock that historically was mined as tin-bearing feedstock,” Mr Ferguson said.
“This area had previously been categorised as waste material in our current mining and financial model due to a lack of drilling data and under our current model, is pre-stripped as waste before ore can be sent to the processing plant.
“These positive drill results unequivocally demonstrate this is not the case and this material may be remodelled with increased confidence as revenue generating ore once all of the assay results are returned.”
“The company is waiting on further assay results, with the targeted drill programme soon to be completed with only one hole currently underway.”
A highlight from the latest results was a A203.3m section measuring 1.59% Li2O & 1,014ppm Sn from pit floor “wedge”.
According to Mr Ferguson, the potential benefits from confirmation of the “wedge” pit floor material as Indicated Resources under the JORC code will possibly include:
AVZ will collate the data and re-run the models to calculate both geological resources and then mineable reserves to be fed into the optimised feasibility study expected later this year.
