Good reporting starts at the outcrop: the original document. This page explains where our reporting on Colombian stocks and mining in Colombia comes from, and what we do when we get something wrong.
We would rather you check our work than take it on faith. So every article links its sources, and every mistake gets fixed in the open.
Our sources
We work from primary sources first. For the Colombian mining companies and exploration companies we cover, and for the rules they work under, that means:
- Company news releases, as issued by the company.
- SEDAR+ and exchange filings, including financial statements, management discussion and analysis, and material change reports.
- NI 43-101 and JORC technical reports, the source for mineral resources, reserves and technical studies.
- Colombian government sources, including the ANM (Agencia Nacional de Minería, the national mining agency), ANLA (Autoridad Nacional de Licencias Ambientales, the environmental licensing authority), the Ministerio de Minas y Energía (the Ministry of Mines and Energy) and other official bodies. These sit at the heart of our policy and permitting coverage.
- Court and arbitration records, where a dispute bears on a project or company.
- Reputable news outlets in English and Spanish, credited by name and used for context.
Every article links its sources. Where a link is not possible, such as a document we obtained directly, we say what the document is.
Translation of Spanish sources
Much of the primary record in Colombia is published in Spanish. We translate it into English for our readers and link the original so you can compare. Translations of laws, decrees and resolutions are our own working summaries, not official translations. Where the exact wording matters, we say so and point you to the original text.
Field note: If a translation looks off to you, tell us. Legal Spanish has its own turns of phrase, and a second pair of eyes is always welcome.
How to report an error
Email [email protected] with:
- the link to the article,
- what you believe is wrong, and the correction, and
- a source that supports the correction, if you have one.
We read every message. You do not need to be a subscriber or a professional to flag a mistake.
How fast we fix it
We aim to correct a confirmed error within one business day of confirming it. Some checks take longer, for example when we need to go back to a company or wait on a government record, and we will not publish a correction until we are confident it is right.
How corrections are noted
When we correct an article, we add a dated note at the foot of the article explaining what was changed. We do not quietly rewrite the record. Small fixes that do not change meaning, such as a typo or a broken link, may be made without a note.
Updates versus corrections
A correction fixes something we got wrong. An update adds new information that was not available when we published, such as a new company release, a regulator’s decision or a comment we were waiting on. Updates are also dated and noted at the foot of the article, so you can see how the story developed.
Our wider rules on independence, technical disclosure and AI use are set out in our editorial standards and Disclosure & Editorial Policy.
Thanks for helping us keep the record straight. Every correction makes the map a little more accurate for the next reader. Questions are always welcome on our contact page. Follow the Vein.
