Ceca de Montesclaros - private mint

Hello!
In Spain, there is a private mint "Ceca de Montesclaros", which produces coins of different countries - Gambia, Sierra Leone, Zambia, Burundi, and others - http://cecademontesclaros.com/
I have a question - whether it is official releases? For example, Zambia coins minted at this yard, first here have been placed on the list of official releases, and then they were transferred to tokens section - https://en.numista.com/catalogue/pieces69785.html
