Ann: Rare Earth Ironstone and Carbonatite Drilling Update, page-43

No definitive evidence one way or the other as to how far the carbonatite may extend.

Some images for you to make up your own mind.

No outcrops along the river valley other than the carbonatites at C3/C4.

Government Geology



Blue dashed interpreted carbonatite margin - Open to south east at present. All RC holes and sentinel interp shown fro C2-5 area. Red star at end of extended access - drilled?

Two carbonatite outcrops were drilled by DRE and are outlined in red. Of special note are two further outcrops mapped as being similar on the NE side of the Lyons River and LR fault.
Government mapping puts these limestone/Dolostone outcrops in the Edmunds Group sediments

Section Line shown

Drilling and DRE mapping has shown the outcrops on the southern side of the river to be carbonatites. What is the relationship of the northern outcrops to carbonatite??
This early HAS geology suggests there are carbonatite dykes and sills along the NE of the Lyons River. Government mapping seems to put them into the PoGA class of Ultramafic dykes and sills. (purple wiggles coming out of the Lyons river fault and splays (along with ironstones N and S).



One possible indicator of the main body of Carbonatite could be these dykes and sills. If so there may be another 3+ Kms to test to the SE from the red star (recent drill hole?).

The river valley has only weak braided patterns to the SE.
Some strong magnetic features on the NE margins of this low amplitude magnetics may be related to either the "limestone" or ultramafic dykes and sills.
Government low resolution magnetics show some possible correlation with "limestone" (Red outlines)




========================
Summary

• No definite SE margin until drill tested.
• Suspect a minimum of another 3 Kms beyond current drilling (red star?) based on dykes and sills on NE side of river.
• Could be open for in excess of 10Kms - no outcrop, drilling or geophysics to constrain.
• Hint the carbonatite could extend another 5-700m to the NE of the C3 infill and up to 1Km NE from C5 extension drilling. "Limestone" outcrops mapped by GSWA geologists. If correct part of the larger carbonatite would be on HAS ground.
• Linear zone of magnetic highs correlates with possible carbonatite outcrops on the NE side of the river.
• Larger carbonatite footprint would need a lot more drilling with no guarantee of success. Still gives the chance of success to locate something economic.
