AVZ Minerals delivers more strong results from resource extension drilling at Manono
Night shift drillers at Roche Dure.
AVZ Minerals Ltd (ASX:AVZ) continues to deliver strong results from mineral resource extension drilling at the Manono Lithium and Tin Project in the Democratic Republic of Congo (DRC).
The company has fielded encouraging results from the third consignment of four drill holes out of 45 originally planned resource drill holes at the Roche Dure North-East Extension.
Originally, the drilling program design was only meant to be for 45 holes, however, AVZ expanded this after a significant change in the geometry of the orebody meant that deeper drill holes were no longer needed.
Results from these holes confirm further widespread, high-grade spodumene lithium mineralisation including 113.33 metres at 1.79% lithium (Li2O) and 860ppm tin which includes a higher grade zone of 36.0 metres at 2.06% Li2O and 887ppm tin.
Notably, the 54 samples returned values greater than 2% including five individual samples grading greater than 3% Li2O with the highest value being from hole MO22DD009 from 56 to 58 metres downhole grading 4.39% Li2O.
Results from Section 8,400mN are evidence of the Roche Dure orebody dipping at significantly shallower angles than from the current orebody model.
This is significant in that it gives AVZ a better understanding of the shape of the orebody, which has allowed it to reinterpret the location of the upper pegmatite contact as well as tracking some higher-grade zones within the orebody. In effect, Roche Dure remains open both along strike and down dip.

Demonstrating solid grade
“Despite recent holdups at the assaying facility in Perth due to unprecedented demand for lithium analyses, our third lot of four holes drilled at Roche Dure, continue to demonstrate solid grade continuity both along strike and down dip from the current open pit design,” AVZ’s managing director Nigel Ferguson says.
“Drill hole MO22DD010, however, demonstrates late-stage metasomatic alteration of the pegmatite which is found in some places. 48 holes have now been completed with 33 holes sampled and dispatched to the laboratory in Perth.
Additionally, eight holes have been geotechnically logged and selected core samples sent for specialist laboratory tests to allow for a new mine design to be created once the updated JORC2012 compliant mineral resource estimate is completed.
“The objectives of this current round of drilling are to shore up future mineable reserves based on a likely upgrade of resource tonnes generated from this current round of drilling.
"It should be noted that this drilling program has filled in existing gaps in the current geological model caused by previous access issues in wet areas and that the drilling will extend our knowledge of the Roche Dure orebody for a further 600 metres of strike length up to section line 8,400 metres north.”

Or did it take the board two weeks to organise to get flights over there. That seems more realistic
