A new thread for what may come for Minyari Waca and ?? future developments.

Yesterday's PFS announcement for Havieron sparked further discussion about what could happen at Minyari/WACA. With the good results from recent drilling an increase in the MRE for both is on the cards to be followed, hopefully, by a PFS then in due course a DFS and a decision to mine.

As far back as 2017(?) RM was arm waving about a combined open pit and underground decline approach to M/W. My translation of the comments at an AGM. Results from subsequent drilling would support a variant of this - again, hopefully, with modifications for good results.




Recent drilling has added Minyari East, and sentinel interpretation shows other targets may be receiving fairly intense scrutiny. Hopefully (using a lot!), the results will reflect GGP/NCM's experience at Havieron.

One of the strong messages from the GGP webinar (I watched live) was the "surprise" addition of the eastern Breccia along with positive results from the well defined magnetic gravity anomaly. Shaun Day talked about depth potential many times for Havieron (to the centre of the earth - won't be but there is a strong chance mineralisation will extend below practical mining depths - no reported bottom limit at Telfer, Winu, Calibre that I am aware of.)

Recent start up mining at Karlawinda is a reasonable model for AZY's future trajectory to development. It gives a ball park figure for Capex which could apply to M/W and therefore what AZY need to be looking at.

Havieron's cover adds a premium to cost, development time that has resulted in a stage 1 development which IMO will likely be followed by NCM ramping up to stage 2, 3 ..?4 down the track with some form of additional and multiple block caving "headings", decline(s), conveyor systems (perhaps even all the way to Telfer).

By 2024 the hungry beast at Telfer could be looking around for more feed beyond the c2Mtpa high grade feed from Havieron to feed mill train B (higher grade train apparently). NCM could be dusting off projects in their own backyard where plenty have received enough to generate early stage, non Jorc compliant?, resources. There has been drilling at Backdoor in the last 12 months or so as well as some other sites showing up on Sentinel towards Telfer.




NCM's actions show a strong commitment to keeping Telfer operational for many decades. There is a good chance AZY will benefit from this in some way which leads to feed for the hungry beast that is HC speculations.

===============

Access to Havieron appears to be via two routes.
NE from near Telfer to access along the swale between sand dunes all the way to Havieron. Longer route.

There is a another route with a cut off from the Punmu road some 50 Kms along it from Telfer shown on a map in the PFS document.

This requires crossing some sand dunes and salt lake country.

Upgrading existing access Telfer to Havieron or creating new, more direct ones is going to be a very important aspect of ESG IMO. How this is resolved may shed some light on the discussion regarding where to send any Minyari/WACA future ore (if any - there almost certainly will be some which is the purpose of this thread).

Staying on or close to topic is IMO important for threads like this one so it doesn't lose focus by discussing the plethora of other issues that are better in other threads.
