RE:RE:CW fossicker bread crumb trailIskyhigh and Silverwhere,
I have spent quite a bit of time looking at GEPro today and had a few picture grab, but unfortunately SH stripped out the pictures that I attempted to attached. Unless, one of you show me (use pm if you like) I will have to describe what I have observed, hoping that you can expand it with a picture.
I will use Silverwhere's picture as a reference, since it has some info such as the tenements so I could use. This is the picture where that has the red blob to indicate the "current drilling". Comments and observations follow.
1. Purdy's: The bottom corner of the red blob seem to touch the x-section line (the black line drawn on Novo Corp Presentation slide 15). The x-section itself is shown in Slide 16 (it took a while to figure out what Novo was showing, clever people). On slide 16 there are two fault lines, One is in the Purdy's tenements (I believe this is the one referred to by Iskyhigh as the SW-NE fault, the longer one (could be the bread crumb trail).
2. Now if you bring up GE Pro, the 2015 picture has 4 major shades:
- dark brown: cooya pooya rock, usually they have the highest elevation in this area.
- ligh reddish brown: conglomerate with liberated quartz cobbles like the photo show on the web for CW landscape.
- greenish: dry/wet creek bed with vegetation. If there is a pool of water then there are trees around the pool.
- white: In ribbons with various thickness = rhyolite, sandstone, quarts ???, I am guessing.
Start with Silver's picture from the left. (E47/3601), there is a vertical hairpin brown rock with a narrow waist at the bottom (a pass?). A white ribbon starts from there and going in a SW-NE direction. A greennish dry/wet bed creek just follows that ribbon on the north side. The elevation of the creek bed is a few m lower than the white ridge, but that ribbon continue into Purdy's bottom left corner (E47/1745). Just passing the red blob, the creek bed turns abruptly NW, then north, then east toward the Harding River. The elevation of the creek bed reduces from about 100m to about 83m at Purdy's and Harding River, near the Dam has an elevation of 40-50m (the Lake has an elevation of 60m).
In sum, the flow of water if there is any significant amount is in the SW-NE direction toward the River and the sea. My speculation is that this creek bed coincides with the fault = the fossiker bread crumb trail.
It's not always 100% correlation, but most rivers tend to find fault lines to discharge the water to the sea (I can see geos are all over me for this conclusion).
3. Another observation: Back to SilverW map, just about 1.6 km to the west of the label E47/3597 (the blue corner touching the white ribbon). Zoom in that corner using GE Pro you will see a network of streams feeding that portion of CW. This greenish area is at a higher elevation than the white ares and the creek bed immediately north. So, we would expect things (e.g. nuggets) to get washed down the slopes? It should be noted that the area is sounded by high grounds (dark rock, one of which near the corner of E47/3597 is at 147m. I would suggest Novo send someone over with a metal detector and a jack hammer.

For a few reasons; 1 - the NWC extent of the conglomerate on Purdy's heads that way (as shown on the the 3d), 2 - I believe one of the geos had indicated exploration was proceeding that way (I recollect he did it via a gps located pano photo) and, 3 - general airphoto guestimate.
The dashed breadcrumb essentially follows the historical geological interpretation, which would make for a smaller target or targets, presuming the fault follows as speculated.
I'm probably wrong.
