A quick note!
“China’s [rare earth] processing industry, and its downstream metals and magnets industry, are effectively a coffee maker. Myanmar goes into the top of that coffee maker and gets ground up with all of the material mined in China, the other material imported from abroad…and then it all feeds into metal factories and magnet plants, and therefore, there are some grains of coffee inevitably that will be from Myanmar.”
“Unless you’re on the floor and you can kind of track the molecules down the separation line and then follow it to a metals and magnet plant, it becomes really, really tricky.”
-Ryan Castilloux, founder and managing director, Adamas Intelligence (critical minerals supply chain tracing company)

Context
Challenge: Data scarcity
With that in mind, here are some methods I used:
INTERVIEWS
For this reporting, sources included mining workers, local community members, academic researchers, NGOs, supply chain tracing experts, activists, civil society workers, and armed group spokespersons.
→ Due to source safety concerns, most interviews were anonymous and many were off-the-record. Still, each interview helped to build up a better understanding of the industry.
→ Sources have also provided valuable photos, videos.
→ To protect vulnerable sources, removed metadata + identifying information from photos/ videos before publishing.
→ Due to the data/ information vacuum, rumors spread easily. It has been important to differentiate between firsthand and secondhand information from sources, and to cross-check information with other data sources.

PUBLISHED REPORTS
News/ media articles, academic research, NGO reports
→ Published reports can be a good source of visual evidence (with additional verification)
→ Propaganda outlets sometimes have useful clues/ information that may not be published in other places.
→ Small, local outlets often publish detailed accounts of daily news and events.
→ Check reports on other industries with overlapping business networks/ supply chain pathways.
SOCIAL MEDIA RESEARCH
→ Useful for identifying visual evidence, researching people, companies, networks
→ Identify key accounts and trace comments, tags, followers to understand networks
→ Can help to develop timelines of key events (with proper verification)
→ For key posts/ visuals, important to verify posting date/ caption (geolocation, chronolocation)
→ For digital safety, use a research account/ anonymous browser, VPN. Download/ save important material in case the post gets taken down.
→ Different social media platforms may have unique value (For this project, we mainly used Facebook, TikTok, Douyin and Telegram).
→ For this project, we looked on anonymous/ propaganda accounts, business pages, work recruitment pages, buying/ selling pages, public posts from family members/ friends of businesspeople.
→ Even if an account is not trustworthy/ reliable, it may still have useful information.

CORPORATE RECORDS
→ Do not take all corporate records at face value. However, even incomplete/ falsified records can reveal useful information about business networks and the ways businesses operate.
→ If working across multiple alphabets/ languages, be sure to check for different spellings.
→ Check multiple ways of writing a name (abbreviations, name order, use of middle name) to catch all information.
→ Cross-check information as much as possible (birth date, ID number, photo, etc) to avoid mistakes.
→ Key businesspeople may use proxies like family members or close associates on company documents.
→ Collaborate with specialists for large datasets, complex network analysis.
CUSTOMS DATA
→ If the country you are researching doesn’t publish import/ export data, look at data from other countries that import/ export to that country.
→ Seek out expert assistance in identifying relevant HS codes.
→ Can look at import of necessary supplies as well as export of product
→ Cross-check with other data points as much as possible.
SATELLITE IMAGES
→Identify partners with access to different image sources, expertise
