RE: O'Callaghans, Rio JV, 3rd train for Havieron25 Aug 2025 15:21
On a third train at Telfer, this was discussed elsewhere with a Telfer employee/ex employee who gave this (non expert view) which is worth sharing.
- I really don’t think a third train would be viable. My thoughts are that Greatland seemed pleasantly surprised they are able to project enough life out of Telfer to keep the mills fed until Haveiron’s ore becomes available.
To build another train.., well I can’t see how that could be ‘tacked on’ to the existing set up. It can’t go immediately adjacent, you need to get a 300t crane on both sides of the existing mill building for maintenance- and fairly regularly. It’s difficult to appreciate the sheer scale of the mill building, the ball mills are bigger than most site’s SAGs, and while I appreciate you wouldn’t need the same scale for another train, you’d need a whole building with a feed conveyor, a SAG, screens, cyclone feed pumping arrangement, cyclones and gravity circuit, ball mills, screens and flash floatation, and somehow get the concentrate to the existing gold room. And that’s just the mills, then you have the floatation circuit all the way down to the copper press, and the waste from the SAG.
Just one logistical example - they can barely house enough folks for shutdowns as it is, let alone accommodate huge construction crews on top of this.
