Impact is the average of the four parts, rounded, plus one point when Canada is directly hit on two or more channels, up to 10.
Two separate scales from 1 to 10. Strature never multiplies or merges them.
Why it matters
Panama's large copper mine in Donoso has been shut since the Supreme Court struck down its contract law on 28 Nov 2023. A government audit found most environmental commitments met, and ministers are preparing a recommendation. Environmental groups reject the audit; no decision is due before the end of 2026.
Why Likelihood 5 Pushes: government intent, fiscal need, authorised talks with the operator. Brakes: the 2023 court ruling, slipping dates, organised environmental opposition. Named sources on each side: an open contest.
Why Impact 4 Estimate (the decision moves no sized sum in the window). A restart is a gain.
The other facts on file (5)
- The Supreme Court declared the contract law unconstitutional on 28 Nov 2023, after weeks of street protests [1] (9 Sep 2026)
- Audit delivered 19 Jun 2026; the environment minister said the mine met 87.64% of 370 auditable commitments, with nine operational failures; a recommendation should reach the president before the end of 2026 [2] (14 Jul 2026)
- President Mulino said a reopening would carry no concession contract; the mine was about 5% of GDP and 75% of exports [3] (19 Jun 2026)
- CIAM's Lilian Guevara said the audit is neither independent nor comprehensive (Strature's translation), and the Mesa Técnica para el Cierre de Minas asked that it not be accepted as comprehensive; the government has authorised talks with the operator and the processing of 38 million tonnes of rock already extracted [4] (29 Jul 2026)
- The government says no mine decision will come before year-end; royalties could exceed 0.4% of GDP; an adverse arbitration outcome could cost up to 19 points of GDP [1] (9 Sep 2026)

Not under wayChannels 4 on the card
- CanadaThe operator is Canadian [3]; no Canadian loss sourced (a restart is a gain).
- Public financesA restart could add more than 0.4% of GDP in royalties [1]; the mine was about 5% of GDP and 75% of exports before closure [3].
- ArbitrationClaims of about US$27bn are suspended pending the decision [2]; an adverse outcome could cost up to 19 points of GDP [1].
- ProtestsWeeks of street protests preceded the 2023 closure [1]; groups still want the mine kept closed [2][4].
Three scenarios and their signposts
- S1
Restart authorised
The ministers recommend reopening and a decree or agreement follows in 2027.
- S2
Stockpile only
Treatment of extracted material continues and the restart decision slips.
- S3
Closed for good
The government opts for a closure plan.
| Path | Signpost |
|---|---|
| S1 | The ministerial recommendation delivered |
| S2 | No recommendation by end-2026 |
| S3 | Arbitration claims revived |
No probability is given for the three paths.
