I have not made this recipe but I have made raw chocolate before. A tip for those who don't have a high power blender is to melt the cocoa butter by placing it in a bowl over a pan of hot (but not very hot) water for a while. (So long as the butter isn't above body temp. or something like that it's considered raw). Dry grind the cocoa nibs and goji berries separately, place them in a blender, and with the blades running, pour in the butter and blend till smooth. Alternatively you can mix the berries, nibs and cocoa butter by hand though it will not be as smooth.
