Telfer has 4 shafts, with 2 large high voltage vent fans each in a sort of ‘Y’ configuration. All 4 are extraction, and the fresh air is drawn in through the portal. On the surface is a huge chiller room with fans that blast cooled air in to the portal to be drawn down to the bottom, as you can imag...

The circumstances at Telfer won’t improve any time soon. With the current tails dam issues they have stated that the plant will be offline until at least September, best case scenario. Having said that, Newmont absolutely has to resolve the tails dam issue whether they sell it, keep it or close it, ...

Hopefully moving forward;

Better news than expected… power hopefully back on within 24 hours (need to replenish fire suppressant gas cylinders first, on its way from prob Perth I guess), and with tails dam situation, hopefully get a train back up and running within a month. Not ideal but I’d expected heaps worse on both coun...

Another hole in the tails dam the following day, a crack in dam wall weeping slurry….

…and a fire in the power station.

Somebody has irritated the Gods.

Seems odd to blame ‘heavy weather’… it hasn’t rained for a month.

Nevertheless that’s the least of their problems in the last couple of days….

Word around the campfire suggests that Telfer has again shut down its mills due to having discovered another hole in the tailings dam, in a different area to that discovered on Dec 24th last year. Not good, Let’s hope it’s not as significant as the previous one, I assume there will be a prohibition ...

Yep fair call, I’ve never been in an underground mine. But I do know that telfer’s UG crusher has a lot of down time from being bogged, though as you say they maybe feed the crusher from different levels to where blasting is taking place? Utilisation also depends on the COS not being too full, ie tr...

Hydrogen I think that might be a little optimistic regarding the availability for the winder at Telfer. I say that in the context that the winder is less of an issue than the circumstances that surround feeding it. For the winder itself, the cables basically never need to be changed, there are four ...

Shinybits ... thx for the info .. I had to laugh at your mention of topsoil .. I think it is desert and there are tons of sand all around .. so I would not worry too much that 😂 depending on how it is done and not to ruin the habitats ! Yeah mate as Hrydrogren said, it’s owned by local indigenous g...

…how much non-telfer feed does telfer process? Zero, zip, yada Train one processes dirt crushed underground and fed to stacker 3, as well as pit dirt sourced from crusher 1. Train two uses surface material from crusher 2. To use dirt from anywhere not exclusively owned by Newmont would require an e...

The rehab cost of $160M would be the stuff of dreams… the head enviros and engineers at Telfer and the off the books word from DMIRS suggests a conservative figure of more like $5-600M (AUD that is) and apparently the available volume of topsoil required has been grossly underestimated for one thing...

Ah ok, hopefully there’s enough capacity in it for another avenue if needed. You’d think so, surely.

I’d also say that it sounds like you don’t want Havieron to be successful which quite obviously it’s going to be. To suggest I don’t want Haveiron and/or Telfer to be an ongoing success is laughable and very much not the case, and all because I don’t conform to your frenzied optimism? My apologies ...

Hi Shinybits, why would a new gas pipeline be needed all the way from the coast. Surely they would only have to extend from Telfer. My understanding is Newmont do not own the pipeline? I could be wrong here but I’m pretty sure Telfer own the pipeline. It doesn’t service anywhere else in the vicinit...

It would be more efficient plus running off renewables. Telfer has 3x 40Mw GTs and need all 3 in summer… 2x SAGs @ 15Mw each 2x Ball mills @ 13Mw each Then there’s cyclone feed pumps, stacker feed belts, underground vent fans, process water pumps, raw water pumps, tails pumps, tails booster pumps, ...

I’m not suggesting it’s not viable, I’m merely pointing out that ALL things considered it’s not quite as rosy as some folks seem to believe, and we need to look beneath the surface (no pun intended) and look at all the reasons that would make it a good proposition. If Haveiron was still worth the co...

IThat quote about whether Havieron is viable yet is a bit naive, it already has a mine plan, a PFS, an MMRE, and 2 more MRE revisions. The Decline is nearly at the ore. The ore grades are 10x higher than Telfers, it’s 3mt per year will give the same gold and copper than 30mt of Telfers Fair enough,...

Thanks for your input.
Just a question. Are you talking AUD or USD?

SoS

Ah yes, sorry mate that’s $AUD, and according to far more knowledgeable folks than myself, that’s pretty conservative.

Yep but it has also been verbally stated by a DMIRS officer (admittedly that’s hardly official) that the rehab funds reserved for circumstances in which a mine owner could not afford to meet their commitments would be very much swayed toward mines closer to population centres, ie with bigger potenti...
