How to read a score. Each score rates how good or bad the news was for the company, from −10 (clearly bad) to +10 (clearly good). 0 is neutral, and anything beyond ±6 is strong and rare. It rates the coverage, not the share price.
Company by company
| Company | Tone | Stories | What the coverage was about |
|---|---|---|---|
| Rio Tinto | +5.0 | 19 | Coverage was dominated by Rio Tinto's funding of a cane toad barrier in the Pilbara, which reflects well on it. |
| Anglo American | −2.3 | 8 | Coverage centred on the extended deadline for the nickel sale to MMG and a share price dip that lagged the market. |
| Glencore | −0.8 | 5 | Coverage was mixed: the shares fell and its Kazakh zinc output dropped, while copper guidance holding and its investment in a nickel project were more positive. |
| Antofagasta | +3.7 | 4 | Coverage was mixed: stronger third-quarter copper output and a higher analyst price target were positives. |
| Endeavour Mining | −6.7 | 4 | Most coverage was about underground operations at Mana stopping after an access ramp subsided, a clear operational difficulty. |
| Fresnillo | −5.2 | 3 | Coverage centred on a share price fall that lagged the market and questions over whether full-year targets can be met after a softer quarter. |
