How we work

Methodology

This page describes how Årebladet obtains the material its investigations are built on, where the limits lie, and what we choose to redact in the source references attached to a published article.

What is an exploration permit?

An exploration permit (undersökningstillstånd) gives a company the right to look for metals or minerals within a defined area of Sweden, normally for three years. The permit does not grant the right to mine; that requires a mining concession (bearbetningskoncession), which is assessed separately and to a considerably stricter standard. Permits are decided by Bergsstaten (the mining inspectorate), which is part of Sveriges geologiska undersökning (SGU, the Geological Survey of Sweden).

Sources we work with as a matter of routine

For foreign parent companies and investors we use ASIC (Australia), Companies House (UK), SEDAR+ (Canada) and similar foreign company registers. If the company is publicly listed there is also a lot it is required to publish and be transparent about. If it is on its way to an IPO, a great deal of new information is released for the first time.

For information on the companies themselves, the companies' own websites are an important source : for what they write, what they don't write, and how they change the page over time.

What we have to pay for

Some of Bolagsverket's material is only available for a fee, for instance personal details on board members, complete historical change filings, or original foreign extracts. We buy those records when it's justified for a specific investigation, never as routine. Keeping costs in check matters.

Data security

Our research happens in a separate workspace from publication. That means raw data we ingest (bulk registers, email correspondence, OCR'd PDFs, personal identity numbers) never goes straight to the web. Before anything crosses into the publishing repo, Pär does a manual review:

Verification

Every factual claim in a published article links back to its source. Click the number after a paragraph to jump to the reference list. The company's right of reply is documented: when we haven't received a response, the article says so.

Corrections and updates

We don't make silent edits. Every change after publication is logged in the public changelog (currently maintained in Swedish). The first published version will always be available as a reference.

Technology

The site is built in Astro and rendered as static files for our web host, Hostinger. Interactive elements (the polygon map, the ownership-chain network graph) only load when the reader scrolls to them, so the article is readable immediately even on a slow phone. Maps are drawn with MapLibre GL; the ownership chain with Cytoscape. Printed maps, and some of the maps here, are rendered by our own QGIS-based mapping tool Pärmaps, whose colour palette is also used on the web so that map, print and text stay in step. The same technology underpins gruvkartor.se.
