    Ahh yes the HC follow up to the erroneous and false but positive claim met with unbridled enthusiasm is to attack any poster who tries to correct said untruths or inject a little realism.

    Let me spell it out to you scanno,
    1. sonofdavid stated:"its rare to get the highest concerntations on top". Totally wrong. Supergene enrichment commonly produces a zone of gold enriched wrt the fresh rock orebody in well developed weathering profiles. The weathering process occurs most rapidly in areas of high heat and high rainfall, i.e. the tropics. i.e. Brazil. You will also find supergene or lateritic Au enrichment in areas where ancient tropical weathering profiles are preserved and the climate is now arid i.e. Western Australia. These zone of enrichment may be removed by later erosion, however the lack of one does not in any way make the, it gets richer at depth statement, true.

    2. sonofdavid stated:"if the geology holds up they will be deeper and richer as they go down" You cannot say this. As it not a statement that can be made without first drilling the prospect. Gold forms at various depths dependant on the style, epithermal is formed at generally <1km, porphyry Cu-Au is around 1-3km depth and orogenic Au (most WA deposits) formed around 5-7km deep. Gold deposits commonly have a higher grade core, though not always the case, as tabular vein systems commonly show localised high grade zones due to structural flexures and interactions. Given that the Au formed at depth and they are now present at the surface means that usually many kilometres (yes kilometres) of rock has had to have been eroded to expose these deposits. That the current erosional surface now cuts the deposit, how can you know in advance where that intersection is? Is there still 90% of the system remaining or is what is left just the lower 30%?? Add to that, that the deposits are often folded and rotated from their original orientation so that the old 'up' may now be sideways or even down. How can you make a statement that the deposit will likely get richer as it goes down??

    As I said I like the Crater Mt story, there are no arguments from me. I think that there is a lot of potential there. However regardless of it's proximity to existing deposits and the historic intersections, all Crater Mt has at the moment is potential. There is currently no orebody there. One or two phases of drilling should be able to give us a good indication as to if there is a sizeable system there. If that is the case then those that hold now will be very happy campers.
