Ann: Exceptional Metallurgical Results at Earaheedy Project, page-17

Cannot be too definitive about your Qs.

Predicating some comments on the exploration target and continual drill result it is receiving this could be a multi decade mine which would follow a fairly well travelled route to getting product to market.


IMO Earaheedy is not too remote but it will add significantly to Capex because of where it is.
[Certainly wouldn't want to walk there and carry anything especially in summer]

Think Tropicana (500 Kms out of Kal but with a bulk commodity (that adds a few twists) rather than gold.

A camp, airstrip, and local water supply are essentially a given. Road upgrade?
Power - ESG probably means a mix of Solar, Wind with Diesel and possibly a gas link (believe the latter happened at Tropicana/Sunrise Dam). Apparently OZL have a $500M contract lined up for their remote West Musgrave Project ( Another potential user of the rail from Leonora??)

The Earaheedy project is 150+-Kms NNE of Wiluna.

Certainly need trucks to transport to the bitumen at Wiluna. Then 275 Kms on the Goldfields highway to a rail head at Leonora- or keep going with ???EV trucks.
The Leonora Line received a recent upgrade. Whether rail has excess capacity on top of the other bulk commodities (Ni is main but others?) it needs to move I don't know.

How much concentrate would RTR (??JV??) produce?

Zn
Concentrate 59+-% Zn from samples 1.25-4.72%Zn and 80% recovery = minimum of some 12X concentration for 4.72.
Mine 12 tonnes for 1 tonne concentrate that needs to be shipped. Almost ridiculous calculations so DYOR.
Mine 12Mt ore per annum for 1Mt of concentrate. The ratio would change and overall grade would in all probability be lower

Then there is lead at some 10-50% of the zinc.

Water?
Site water for mett test work.
Quantity and Quality of water?
This has seldom been a major problem for WA projects to date. There tend to be large underground sources of water at varying qualities that can suit person and mill.
Obvious local source for plant water are the Nabberu Lake system which may be poor quality (=brackish to high salinity but good quantity).
Drinking/Potable water may take a bit more effort. Testing water from drill holes along the mineral trend? Various drainage systems feeding into the lakes, basins (Earaheedy, Officer??). Many options for drinking and process water. None likely to be cheap but needed and part of the building a stand alone mine.


Desalination processes have come a long way since the early days of distilling salt water for drinking purposes in the early days of Kalgoorlie pre the pipeline in 1903. To use desalination has become necessary in Chile for some companies that have over used the available groundwater.

Just playing around a little. MRE- SS - PFS - DFS - BFS for little change out of $50-100M will fine tune the above and a myriad of other issues. Hopefully the route to go with Mett looking good being something needed to get the ball rolling beyond what looks like a successful drill out to this stage.
