Adavale drilling hits nickel sulphide veins in Tanzania
Link copied to
Adavale’s ongoing diamond drilling program at the Kabanga Jirani nickel project in Tanzania has intersected mafic intrusions hosting mineralised sulphide veins.
The most recent hole KNE06-16-01 intersected a 25m mafic body from a depth of 30m with portable XRF, which provides a good idea of what’s present, returning readings of between 0.3% to 0.6% nickel and 0.6% to 1.8% copper from two thin sulphide veins.
Additionally, several thin sulphide rich veins hosted in metapelite intersected deeper in core below the mafic unit returned elevated pXRF readings up to 9.5% copper at 162m, as well as 1.1% nickel and 1.8% copper at 234m.
Adavale Resources (ASX:ADD) has just completed the drilling of the seventh hole (KW07-10b-01) of the planned eight hole program and is poised to kick off a 14-hole reverse circulation program with the arrival of the RC rig.
This program will target the strongest gravity anomalies anticipated to reflect prospective underlying mafic/ultramafic intrusions.
“It is very pleasing to witness the progress Adavale has made since commencing drilling operations on our Tanzanian project only 4 months ago,” chairman Grant Pierce said.
“The company looks forward to reporting the full analytical results of the initial drill program once they come to hand whilst commencing its next drill testing phase.
“The additional targets generated by the geological team due to the gravity survey data is technically very exciting. With the introduction of the RC drill rig into the mix we’ve now got the ability to test and evaluate these targets in a shorter timeframe.”
All diamond holes completed to date have intersected broad intervals of metapelite that contained numerous thin sulphide rich veins in places.
Some of the holes especially in hole 1 and more recently in hole 6 and 7, which intersected a 2.2m interval from 334.7m with several thin sulphide veins, reported strongly elevated nickel and copper pXRF readings that potentially indicate the presence of a nearby magmatic sulphide bearing mafic / ultramafic body.
Drillholes 2, 3, 4 and 5 intercepted zones with multiple sulphide veins that explain their anomalous magnetism and conductivity. Some of these veins also carry elevated nickel and copper that may explain their geochemical anomalies. These holes will be further analysed for follow up and RC drilling has been scheduled for Target 12 area near hole 5.
The eighth diamond hole at Target 21 will test a strong gravity anomaly.
