Wow, Aldoro has some incredible rock chips.

The Nb to Nb₂O₅ conversion factor is 1.4305 so Charger's up to 30ppm Nb anomaly is up to 0.0043% Nb₂O₅ as a soils anomaly. I'd have thought soils anomalies are likely to be much lower than a rock chip sample because they are mixed with so much other stuff. I'm not aware of Charger reporting rock chip results. While Charger soil Nb grade is low, it could still be significant because Niobium has a density of 8.57x. While Niobium Oxide is lighter, it is still quite dense at ~4.6x. These are much heavier densities than general rock, Mafic, Pegmatite or Spodumene that are all 3.1x or less. If displaced/shaken these heavier densities are going to sink through dirt/rock rather than rise to the surface. You wouldn't expect much surface expression in soils and from the little I've read about WA1, they didn't have much if any surface expression either - their deposit was identified in from drilling assay's.

While some of the Aldoro commentary of 12 Dec reads as if its drilling, I think its just rock chip sample lines using a hammer to obtain fresh rock. Aldoro have samples up to 1.79% Nb₂O₅ from this surface work (12,500ppm Nb). Their peak surface grades are 400x higher than Charger but a lot of that difference will be explained by soils vs rock chips.



Back to Charger
If the area of the soil anomaly that charger has is 1.7km by 1.8km, are there any outcrops from which rock chip samples can be taken or is the whole area covered by a layer of transported material? The anomaly has size but it currently lacks grade. What I think it needs to get people excited is something confirming grade. If this can't be done via cheap rock chips its going to need to come from the more expensive option of drilling.
