DRE (ASX) Ann: Multiple, Large Scale REE-Nb-Ti-P Carbonatites

Originally posted by salpetie: ↑

Sentinel, and other satellite, near real time imagery are available to those who want, are able, to use it. My post came out after the market closed so it wouldn't have impacted. Others, on their own, could have come to a similar, or better, interp and sold down though there are too many possible innocuous reasons for the apparent lack of drilling IMO to make this a safe course of action.

Time lapse in sentinel is the way I find most useful to try and follow changes - link to methodology. Try it and DYOR if interested - the input resolution does limit usefulness to being generally adequate if not precise.

The images available range from clear and easy to interpret to complete cloud cover and nothing. Generally somewhere in between with the C2 and C1 areas being more tricky for some reason. C3 4 were better but still challenging with the increase in hole density tending to add to the challenge to work out what is going on.

Sentinel does provide ways to try and enhance the imagery that can be useful for specific purposes - vegetation, water, archaeology, alteration and many more (see @Polonium210's posts on geological aspects of this). In my last post there were both 'natural' and false colour images of the same area. My interpretation of these and other variants suggested not much (none?) drilling happened in the period of the last 2 satellite passes.

I suspected a slow down or suspension of drilling between the 30th and 2nd but waited to see possible confirmation from the pass on 5th before posting.

One way to try and see what is happening is to try the near infinite number of band combinations and colour adjustments available. The reflectance around drill sites shows up as a white dot - there are potential artifacts plus variants because of the fly pass timing etc etc. Real vs imagined - tough.

The changes in this time lapse match drilling interpreted to have occurred by 30/11

2nd and 5th time lapse

The 'enhancement' choice is almost random and probably not the best. Still shows something going on that is very open to interpretation.

Give it a try.

5 days with two more satellite passes. Very little apparent - probably missed activity on prepared sites. Most optimistic thoughts would be they went to diamond drilling which left no visible traces at Yin (Perhaps a couple of holes but not all).

Summary timelapse for the last 6 weeks:

Time lapse.
10 October pre site prep infill - holes drilled to #30+ vaguely visible - Hole 27 problematic.
26 October infill sites prepared most relatively obvious.
10 December latest image. Which shows work to late November but not much obvious since 30/11. Perhaps one hole to the ENE of 27?

Time lapse 2nd and 10th December.

Template for phase one drilling, site prep for C3 infill, Phase 1 high Pxrf (red triangles), Obviously drilled in fill in November, not drilled?? in boxes;
Star does look like a drilled site but not prepared before!?

Expect an announcement relatively soon about what drilling was done in this area - Pre- Xmas if work has been finished for the season
