Grade A: Official record

Rida Engineering - 82% owner of UK-sanctioned Omdurman Mining

2013 - 2026

The UK sanctions notice of 16 July 2026 states that Omdurman Mining is '82% owned by Rida Engineering and 18% owned by the state-owned Sudamin Mining Company'; the C4ADS dataset and C4ADS's May 2025 report give the same split. C4ADS describes both as subsidiaries of Rida Group, 'which claims to be a Sudanese company with an office in the U.A.E.', and cites the group's own LinkedIn post about the mine. Satellite imagery in the C4ADS report shows the River Nile State site active in January 2024 and March 2025. C4ADS trade records show sodium cyanide shipped from China to Omdurman Mining in May 2024 with UAE retailer Rowfer LLC as notify party.

Response
No response from Rida Group to the UK designation of Omdurman Mining was found (not specifically searched in Arabic).
Sanctions
Rida Group: none found. Omdurman Mining: UK, 16 Jul 2026.
›Research notes

A is for the ownership split (official notice, read directly). The group-level description, the satellite imagery and the cyanide shipments are C4ADS alone (grade C). Shows that one of the UK's 'SAF gold revenue' companies is majority privately owned; the army link runs through Sudamin's minority share and state levies.
