Have had a another look at some of the historic Archer announcements, specifically the announcement on 05/02/2015.
Shows some interesting things, a lot which is just confirmation of what SF2TH has very effectively posted above. Firstly the EM surveys provide a good signal, just about all of the major anomolies where they have drilled have produced graphite - Sugarloaf, Campoona, Lacroma, Wilclo, Wilclo South, Balumbah, Francis, Cut Snake and Argent. Jamiesons Track is actually Manganese not graphite. The North Eastern anomlies are large flakes, South West with Sugarloaf is Microcystalline, and the South East (Campoona) and North West (Lacroma) more fine flake, most amenable to battery anode.
You can also see the three distinct zones of Lacroma. Where it highlights I think is central, the historical drill for which tranche 1 is the basis. Then you see the east, and then the very broad western zone of Lacroma.
In this announcement it shows that Archer did actually test the East of Laroma, but didn't discover anything material, I suspect based on ITM's work because they didn't drill deep enough. They only drilled to 77m max, whereas ITM work suggests the likely mineralisation is at depth - have a look at some of SF2TH posts above.
This is shown on the following. Where you can see the drilling they did in the East. Then you can see historic drilling at central, which formed the basis of current drilling at Lacroma, given they knew there was significant historic graphite intercepts there. But then potentially most significantly, have a look at the anomoly on Western Lacroma, how much more intense it is. As SF2TH has identified from the underground angle, the anomoly is intense near surface and much broader than central. Going to be interesting to see what is causing that anomoly if/when it is drilled, along with the drilling already done on Central!
