News: SFR Sandfire Resources NL provides FY17 production guidance, page-12

Argonaut Secs has very recently (last friday) promoted SFR as a 'buy' with a $5.80 target.

SFR has been active expanding its exploration portfolio to the west and south of DeGrussa and Monty, as per this slide from the last Presentation.

The west is the same or very similar geology to DeG and M and all are also in the Bryah, and near where either IGO/ALY or RNI is exploring for VMHS cu/au or MLX is focussing on gold (Peak Hill area).

The south is predominantly the Yerrida basin where SEDEX copper is probably the target, but a small part of the ENT area is Bryah-VHMS.

I think that the expansion can be interpreted as demonstrating confidence in the whole area.
