According to the nomads who sold these meteorites to Ahmad Bouragaa, that meteorite was found on the border between Mali and Mauritania, whithout more accurate details. Several kilograms of other lunar meteorites were found at the same place.

Geochemistry of NWA 10546 : Olivine (Fa23.1-39.3; Fa86.9; FeO/MnO = 83-95; N = 4), pigeonite (Fs21.7Wo13.9; Fs54.2Wo21.9; FeO/MnO = 52-65; N = 2), augite (Fs13.0Wo37.8, FeO/MnO = 39), subcalcic augite (Fs32.8Wo31.9, FeO/MnO = 49), ferroan augite (Fs51.5Wo40.5, FeO/MnO = 72), plagioclase (An90.3-93.3Or0.4-0.1, N = 2)

NWA 10546 is probably paired with NWA 7834, 7948, 8306, 10149, 10203, 10263, 10291, 10317 and some more unamed lunar meteorites.
