Quarterly mineral export statistics compiled from the Rwanda Statistical Yearbook 2025, ENVIRONMENT sheet, Tables 5.4-5.5. Table 5.4 reports export volume in kilograms and Table 5.5 reports export value in US dollars, both disaggregated by mineral type (cassiterite, wolfram, gold, and other minerals) for each quarter from 2015 through 2024. Gold volume and value are absent for 2015-2018 reflecting the period before RMB began systematic gold export tracking. The Rwanda Mines, Petroleum and Gas Board (RMB) is the source agency for both tables.
| COLUMN | TYPE | DESCRIPTION | UNIT |
|---|---|---|---|
| year | int64 | Calendar year of the export quarter (2015-2024). | - |
| quarter | string | Quarter of the reporting year. Values: Q1, Q2, Q3, Q4. | - |
| mineral | string | Mineral type slug. Values: cassiterite (tin ore), wolfram (tungsten ore, labeled "Wolfram" in the volume table and "Wolframite" in the value table -- both mapped to this slug), gold, other_minerals (a residual category covering all other exported mineral types including coltan/tantalite and gemstones). | - |
| volume_kg | float64 | Export volume in kilograms for the given year, quarter, and mineral. Null for gold in 2015-2018 (RMB systematic tracking of gold exports began in 2019). Some 2020 values include one decimal place (e.g. 565,993.2 kg) reflecting the source encoding; these are stored as float64 without rounding. | kg |
| value_usd | float64 | Export value in US dollars for the given year, quarter, and mineral. Null for gold in 2015-2018 (same tracking-start reason as volume_kg). | USD |
