How we research and publish

We publish three types of content for wealth advisers, family offices and their clients:
• Event analyses: trade policy decisions (export controls, quotas, entity lists), public support measures and supply developments.
• Metal profiles: uses, production concentration, price history and forms of holding.
• Practical guides: physical holding, custody, documentation and taxation.

An adviser should be able to forward any of our content to a client without rewriting it.

We cite sources in this order of priority, with a link and access date where possible:
1. Primary sources: official texts and announcements (China's Ministry of Commerce, the European Commission, the US Geological Survey, customs authorities, published tax texts).
2. Institutional and research sources: the International Energy Agency, research institutes and centres, and filings of listed companies.
3. Specialist press, cited by name.
4. General press, only when no more direct source exists.

We do not publish a figure without an identifiable source.

Our analyses explicitly separate:
• the facts: what was announced, measured or published, with its source;
• the Procyon reading: what we infer for the physical availability of the metal, presented as interpretation.

When a situation is uncertain, we set out several scenarios and the signals that would tell them apart, rather than a single conclusion.

• No price forecasts.
• No return promises or projections.
• No personalised investment recommendations. Our content is informational and does not take any individual investor's situation into account.
• No content presenting strategic metals without their risks, in particular limited liquidity and the absence of an exchange price accessible to private holders.

Indicative prices shown on metal profiles are based on Procyon Metals' trading activity. Each one states the form (metal, oxide, compound), purity, unit and date of update.

An indicative price is not a firm offer. Most strategic metals have no exchange price accessible to a private holder: a transaction price depends on form, purity, volume and counterparty. Reference price histories are sourced separately.

• Critical metal: a metal on an official list (European Union, United States) because of its economic importance and supply risk.
• Strategic metal: a broader notion that also covers defence and industrial sovereignty uses.
• Rare earths: a group of 17 elements (the lanthanides, scandium and yttrium). Not all are geologically rare; their scarcity comes from separation and refining.
• Mining, separation, refining, processing: distinct stages of the supply chain, often located in different countries.

Every piece of content shows its publication date and, when revised, its last-reviewed date. Content that depends on regulation or taxation is reviewed when the underlying text changes.

When a factual error is identified, we correct the content and flag the correction with its date. To report an error: contact@procyonmetals.com.

Some content is prepared with the assistance of artificial intelligence tools for research and drafting. Publication remains under the editorial responsibility of Procyon Metals, and the rules on this page apply in exactly the same way.
