Azure have provided two pieces of information to determine what the pegmatites are doing under the ground, measured at the surface.
1. Dip degree of 10-20°
2. Dip direction of NW
The assumptions are that all the pegmatites trend the same direction (north-west) and they trend at roughly the same angle into the ground (10-20°).
The pegmatites travel under the ground towards the North-West. It is strongly suggestive that there are multiple layers of pegmatites i.e. what is often referred to as 'stacked pegmatites' which all trend the
same direction, to the NW. So AP11 would be beneath AP12. And there may be another pegmatite beneath AP11 etc.
This is
my current interpretation of what is happening beneath the ground, and this is why I believe AP11 and another yet to be specified pegmatite APxx, has been intersected in the current drillholes. Based on the above NW 10-20° assumption, the AP11 pegmatite trends all the way up to meet the surface outcrop of AP11. Drillholes in blue are not to scale. If you continue the trend of what I am designating as the AP11 & APxx? pegmatites to surface at 20° then it comes out somewhere further SW of AP12 - right where AP11 might outcrop. The same applies for the APxx? pegmatite which would come out to surface again at a similar location SW of AP11 - in a location with poorly outcropping pegmatite.
Based off what Azure has stated and showed:
1. The green section is the AP12 outcrop as provided by the A-AA cross-section
2. The AP11 pegmatite extends under the ground to the north-west underneath the AP12 outcrop
3. The pegmatites have a 10-20° dip angle therefore the 2nd pegmatite intersected in the recent drilling
cannot be AP12 as it would result in a dip angle of something that is near vertical i.e. 80-90°. Similarly, the 3rd pegmatite is likely to be another pegmatite that is not AP12 and potentially not AP11, although it could be related to AP11 if it truncates, or a completely new pegmatite APxx which is poorly outcropping at surface.
Hence why this is my interpretation:
As to the location of the 205 drillhole, this is where it will be in physical space if you compress a 3D space into a 2D shape. Hole 205 is coming towards you 'out of the page'.
