Clarification on Roan Production9 May 2026 11:46
I emailed the company yesterday because I was a bit confused about the production numbers for Roan. We have been told that the recovery percentage at Roan was in the order of 65% so I was expecting to see this reflected in production numbers, ie,
30,000 tpm (throughput) * 1.65 % (grade) * 65% (recovery) = 320 tpm or 960 tonnes / quarter.
The latest update shows that Roan produced about 570 tonnes in Q3.
I had a reply from Cath Drummond who explained that the new centrifuge / dewatering circuit is for ADDITIONAL processing and not reprocessing of the already reported fines and this is expected to produce in the region of 300 tonnes / quarter of additional copper, bringing the quarterly total up to around 900 tonnes / quarter.
So that sets a baseline for Roan of about 3,600 tonnes per year at current throughput of 30,000 tpm. If throughput steps up to 40,000 tpm as has been suggested then we could reasonably expect an upper limit of 4,800 tonnes per year.
Just putting that out there for anyone else who was similarly confused!
