    re: Ann: Drilling Identifies Zones of Au Anom... you guys might be interested in this, it popped up on one of the other doolgunna explorers threads (which is going on a run at the moment) and talks about rre exp targets, info is from july last yr:

    "We have stated numerous times that we are not in the Narracoota Formation or in the Bryah basin. We always state that our prospect is in the Yerrida basin and we targeting the top of the Killara formation. Our map does'nt show Degrussa in the Killara either, we just showed our project was in volcanic rocks, the same rock type as Degrussa. In fact that the rock types are so similar is the reason that the original interpretation which stood until 1998 showed the rocks that host Degrussa, known as the Narracoota volcanics then , folded around on to our project and the whole region was referred to as the Glengarry basin.

    In 1998 the Glengarry Basin was re-interpreted and subdivided down into three basins called Bryah, Padbury and Yerrida with both the Yerrida basin and the Bryah basin being classified as rift basins (and this was done at the same time as the regional geochemical survey we initially used to target the ground). This means that they were formed by the same processes and by the same event called the Capricorn Orogen, what's more the Killara Formation which we are targeting has been described as the stratigraphic equivalent to the Narracoota Formation (ie formed the same way). Here's the thing the Bryah basin is thought to be 1.8 to 2.0 billion years old but poorly constrained (means the age dating is not reliable)and the Yerrida is between 1.9 and 2.2 billion years old but well constrained (reliable age dating data) and both basin formed within the same crustal event (Capricorn Orogen). This is telling us that the Yerrida Basin started forming before Bryah but was still forming when Bryah started (they overlap) and both basins were located adjacent to each other, the Narracoota Formation which hosts Degrussa is one of the oldest rocks in the Bryah so it will be around 1.9 to 2.0 billion years old. The Killara Formation which is what we are targeting is one of the youngest rocks in the Yerrida which makes it about 1.9 to 2.0 billion years old , there is very little age difference and well within the error of age measurements.

    The Goodin-Jenkins fault is the boundary between the Bryah and Yerrida basin and is orientated NE. The location of Degrussa is some distance from this fault and is much closer to another fault which separates the Narracoota from the much older Peak Hill Schist. I think people have been suggesting that this fault is the Jenkins as it is shown to join up with Goodin-Jenkins fault along strike. I would'nt underplay the importance of the Jenkins fault as it a large thrust fault which would be a significant fluid pathway but I would be looking at subsidiary faults splaying off it for mineralization.

    Through the middle of our ground it appears we have evidence of a similar structure that parallels the Jenkins fault. It is along this fault that the regional geochemical anomalies sit and we think is the major fluid pathway we need.

    However saying all that we don't particularly care because we are building up a lot of empirical evidence now that indicates our ground is as prospective as most of the other players in the district and that we have all the right processes in play.

    The upside of us being right is huge, this is what exploration is all about. That is what is significant about the soil results, it has given me confidence that there has been fluids with the geochemical signature for VMS mineralization passing through our area. This is important as we now have quite a bit of good empirical evidence to back what is a largely subjective theory.

    So if this guy wants to restrict himself to the Jenkins Fault or the Narracoota Formation that is his prerogative, in the end drilling will be the ultimate truth machine. BTW way Degrussa is in a very special rock type (hyaloclasite) in the Narracoota which does not extent far either side of the Sandfire tenements and the other only place it been mapped in the Bryah is the South western corner where I have been following companies that have the same unit. RRE is one which is near the Goodin Fault, has historical gold workings, has a strong regional geochemical anomaly but is located miles away from Degrussa.

    I hope you see that a lot thought goes into this and we do have much deeper understanding of the district then what most people realize, I like our play and if I am right then we have enormous blue sky potential"".
