I like all the comments on this topic here. It is good to have the option to discuss this with excellent deposits at Havieron and Minyari already available and hints of others close to the "beast".
Telfer is likely to be the largest deposit in the area IMO. Hopefully not but it has been around for some 50 years as a mine (active for 40-45) with a gap while they decided what to do in the late 90s. The mine and mill were upgraded at that point and has been operational for some 20 years. [Better figures are available as shown by
@alexander J for various aspects].
Current MRE global Minyari dome is 33Mt.
Feb 22 MRE by GGP for Havieron 92 Mt
Both are (likely) going to grow significantly.
The current total of both would feed Telfer's Mill for 6 years at ~20Mtpa. Obviously extracting and transporting ore at that rate is not going to happen. It does give some idea of how well the Telfer Mine has performed over the last 20 years with grades that were probably less than M or H.
@GoGreen1 's post made me look at Greatland's site to see what's up.
Feb MRE
Up from the previous 52Mt and looks wide open for more
The SE Crescent Zone coincidentally has 33Mt MRE at higher grades than Minyari's similar (current) global resource. Under a little bit of cover - Lol.
This section doesn't show the previous MRE volumes.
This plan view shows where some increases in MRE may come from. Again need to check what has already been included but the drills keep hitting more laterally and to depth (open as is Minyari/Waca)

hav 20220428-GGP-Havieron-Exploration-Update-with-images-vF.pdfThey (appear to) have sealed off the problem area in the decline and progressed 313m plus installed a ventilation shaft. At a 1:7 slope the decline needs to be at least 3 Kms long to reach the top of the orebody. Currently 500m??? with hopefully the worst behind them.
=======================
Expensive and complex decisions to be made by AZY, NCM/GGP to feed, or not, the beast.
