What about Avalon . . . are there any indicators of prospectivity beyond scattered salt pans and a narrow, but high, Gravity Anomaly ?
The Avalon area appears to be completely featureless, however . . . |
|
| The Sentinel Hub web site can be used to see if the dune cover has been removed at any time.
It seems that this did occur in early 2017 and some salt pans then filled with water.
Avalon can be viewed in that period as follows : |
|
| Step 1) View the Avalon area on 26/3/2017 using the URL below. |
|
|
| Step 2) Create an Area of Interest |
|
|
|
| 2a) Copy/Paste the text inside the JSON file (below) into the Popup Window |
|
|
| 2b) Press "Upload" |
|
|
| Step 3) Enter "-22.990397,128.567419" (without the quotes) into the search criteria of Sentinel
(aka "Go to Place") |
|
| Step 4) Zoom in to 500m above surface. Done. |

| The 4 irregular polygons on screen enclose the "high SCBA Gravity Anomaly" areas
published in the RCR ASX ann 22/4/2024.
The solid ground surface (usually under-cover) is visible and appears to be mottled with
white patches. The water table has risen moving salts into the salt pans. The colours of
mineral salts are revealed. There are two salt pans 5km SE of Avalon that are coloured
black and one even contains a Gravity High.
Of course there are many reasons that standing water is black, but one reason is the
presence of REE minerals. In Bahia, Brazil, there are three rivers with "black" in their name near BRE's tenements, and they all have the colour of black tea.
Avalon sits in a depression that drains from SE to NW. However the depression is as flat
as a bowling green (grade 0.06%).
BTW : Several "high SCBA Gravity Anomaly" areas at Pokali can be found by
panning 20km to the west. The outlines of all RCR tenements are also visible. |

Is Avalon like Luni ? ( in any other way than the Gravity Anomaly ) |
|
|
|
|
|
|
|
| The "high SCBA Gravity Anomaly" area at Luni can be found by panning 80km north.
Luni also sits in a slight depression. It drains south.
The salt pans south of Luni have also filled with water.
On that same day one of them, 7 km to the south, was also filling with black water. |

? A passive seismic survey was completed but not yet been reported.
? I wonder if any soil samples at Avalon have been scooped up and scanned with the pXRF ?
