Establish the role of each site
Lynas describes Kalgoorlie receiving concentrate from Mt Weld, producing mixed rare-earth carbonate through cracking and leaching, and sending material for further processing in Malaysia. Those activities belong to one connected research question, not three interchangeable suppliers.
Start by assigning each site its disclosed input and output. Keep any expansion or third-party-feed capability separate from the route described as being used. A plant's ability to accept material does not identify a supplier, establish a transaction or disclose the share of feed supplied.
Compare performance at the correct boundary
When reviewing results, distinguish upstream material from downstream separated output. Summing both can count the same contained material more than once. Equally, an increase at one stage does not show that every subsequent stage increased in the same period: stock movement, timing and processing losses can intervene.
For a disruption review, identify the affected transformation and the product needed by the customer. A site interruption could have different implications depending on intermediate inventory and alternate processing arrangements. Keep those quantities unknown when they are not disclosed instead of making the network appear more precise than the evidence.
A useful follow-up question
In an illustrative investigation of a Kalgoorlie interruption, the next question is how the relevant downstream process would be supplied, not simply which countries appear in the chain. Look for dated operator updates about feed, stock and operating responses. Separate the existence of a possible route from evidence that it is available for the period being considered.
Read the chain by transformation
| Activity | Research boundary |
|---|---|
| Extraction and concentration | What concentrate is produced? |
| Cracking and leaching | What mixed intermediate leaves the site? |
| Separation | Which products and reporting period? |
Your review checklist
- Assign each site its own product boundary.
- Do not add successive-stage tonnages.
- Separate capability from disclosed use.
- Investigate intermediate inventory before quantifying disruption.

Are three sites three independent sources?
No. Connected sites may be successive stages in one route, with dependence between them.
Does this route explain every Lynas customer shipment?
No. A disclosed route does not establish every customer allocation, product flow or input share.
