Ann: Lithium Drilling Recommences at Burmeister, page-26

What else was there in the announcement?

DD Core:

• With a wider range of samples, Spod remains the dominant 90%+ lithium mineralisation. When other projects have presented details, there's been some other lithium sources so remaining at 90%+ Spod is good. Projects like Delta's Yinnetharra JORC noted approx. 65-95% Spod so some new areas have zone's that fall well outside the 90% range.
• I've seen DMS test work quoting anything from 12mm down to 0.5mm. Looking at the size of the 4cm length indicator, a good proportion of the spod would appear to be 1mm or larger crystals. This puts it into the potentially good DMS recoveries category. The project may still need DMS plus flotation to get a robust recovery rate but may be good enough for DMS only at startup. Flotation would then be added funded primarily or exclusively out of operational cash flow (Most WA projects are needing flotation for a robust recovery rate).
• At least in these two samples it is simple mining. David has noted several times that mineralisation appears to be throughout the pegmatite. You also go from Black Mafic material to white Pegmatite material. That would mean the mining plan for the earth moving crew is really simple. If you are digging black Mafic material - send it to the waste pile. If you hit white pegmatite, send it to the ROM pile. Simplicity like this should assist to efficiently mine thinner seams (The colour contrast could mean the sorter GL1 is investigating could also help - presuming its an optical sorter).
• TG6 only used 1/4 of the DD24 for assay results so they have 3/4 for other met testwork.

TG6 are looking at Q2 CY2024 resource drilling and now note a MRE minimum pattern of 100m x 50m. That would indicate they also expect a more lenient POW approval in the next few months so as to drill for the MRE in locations that are not currently allowed.

TG6 note:

Yep - the intercept in RC26 is odd so there may be further surprises as the north-south/east-west structure is figured out. If RC017 was increasing to the south at anything around 50m/200m or even up to rates like 100m/200m you would have got an intercept in the 150-200m range. Instead there's a thin intercept at 100m. That makes no sense (yet). More drilling is required to understand that.

These two intercepts could be the same pegmatite, however RC28 from 209m is a little higher than I'd have liked. About 10-15m deeper would have been good because the 17.1m @ 1.66% intercept was only 32.1m deeper than the top of the peg above. 209+32=241m. RC028 was drilled to 264m meaning you are now into minor pinching and swelling scenarios as to why it didn't hit the main peg from RC22/DD24. A lot can change in 200m so all sorts of permutations are still possible.


Unresolved oddities:

• RC27 isn't listed
• The map with the cross section locations of A to A' and B to B' wasn't presented.

Speculation - the cross section map also had something else on it that TG6 decided to pull from the announcement because they just weren't sure yet about it. Was there a C to C' north/south cross section?
