Ann: Exploration Update, page-66

I reckon I just found another 6km of strike for the Tres Estados dolerite to make it ~16km of highly prospective dolerite dotted with workings and soil anomalies.

The blue ellipse in the lower pic is the transcribed location of the soil anomaly 400m east of the high grade Tabocal workings. The aeromag suggests there is another ~6km of dolerite extending from the soil anomaly out to the WSW and would explain why they picked up that ground.

That gives us ~ 36km of dolerite including the Ema dolerite (not to mention the mineralised porphyries).
