I, and 20+ others, attended the meeting today. No formal presentation with the meeting thrown open to questions

=====================
Earaheedy:

Logistics
This post does add some detail to aspects covered in the one above.

A figure of 10Mt of ore mined was mentioned so the transport figure given above is a reasonable ball park. Depending on the size of Earaheedy 50+ years mine life is bandied about which implies improved transport options - paved roads, extended railway as part of broad arm waving. Such considerations are relatively straightforward although way to premature to be more than early thinking.

Water - hypersaline from Lake Nabberu system is very abundant and excellent for processing. A point emphasised on more than one occasion. Likely to be too much of this and so there will need to be a major dewatering operation. As with many lakes in WA this water could be used as a brine for an SOP operation - by product? However, just one option that MAY be available for consideration at a more appropriate time.

Current camp water is from shallow aquifers perched in gravels. Limited supply but OK quality.

Gas from a "hot tap" into the existing pipeline could meet initial needs. The Miscellaneous License applied for could cover this at a reasonable cost ($30M range???? forgot number). Upgrade possible at a cost. Mentioned solar/wind but didn't seem to be on the radar yet.....

Processing
The Mett work needs follow up. For this larger samples are needed which require specialised diamond and sonic rigs. Brett Keillor (BK) said the area is a very challenging drill environment. Perhaps one reason RTR are drilling this out is because of poor recoveries from historical drilling which led RGC to drop the ground (BK paraphrased).

The processing indications to date are that it will be quite straightforward and use relatively little energy.

In the presentation there are examples of beneficiation processes - DMS in particular as trialed at Pering. BK, arm waving again, mentioned such a process could happen in pit resulting in less material needing to be trucked out. Emphasis on arm waving here for something that needs to be tested from much larger samples than already run.

Not strictly processing but where the flat lying units daylight the sulphides have already been oxidised resulting in the removal of the more mobile zinc and a concentration of lead. This material which will probably be extracted as part of any mining process but sent to a stockpile to be dealt with if, and when, there is a way to get the lead out economically.

Drilling Geology exploration

Around 100 holes to be assayed. Mineralised zones are analysed in detail but composite samples are taken away from this to reduce sample numbers and cost.
Didn't ask about RC drilling but Sentinel coverage suggests they may have wound down for the season.
Drill spacing is commonly 200x100 but ultimately will probably need to be at least 100x100m to get close to indicated range that could be the threshold to interest a Major.
Holes at the east end of the Colorado trend are going into competent basement with probable Mississippi Valley Style mineralisation which could potentially be mined underground. There will be a transition from open pit to UG if the STARS ALIGN - my comment without much more basis than what could be a logical progression if a Tier 1 mine develops.
Various experts have scratched their heads about the nature of the deposit.
Pattern drilling seems to be the best way to explore! Tried many routes (mag/gravity/IP(hopeless with hypersaline water)/geochemistry may help but that comes from drilling though perhaps wide spaced with vectors)
Aircore on two traverses where clearance granted plus surface geochemistry on the Iroquois and Sweetwater areas that has been encouraging enough to see infill.

Where to from here?
Wasn't quite certain if the board wants to continue the drilling along strike to try and determine if there is a real sweet spot beyond what has been tested to date. At ~$1M spend per month the kitty runs dry sometime next year. Good results? and an MRE? may be two of the key indicators the board needs to pull the trigger on an almost inevitable cash raise. But wait RTR has other assets which could be monetised - Western Queen? JV or spin out of one or more of the others was not totally ruled out

Wardawarra drilling results not reported as they were IMMATERIAL = poor, to nada. Earaheedy dominating so the comment in the last paragraph about other assets.

My hour is up. She who must be obeyed is hovering dangerously so will close for tonight.

The above is from memory and accurate as such though embellished by me in places. DYOR.
