Mother lode comes from mining, the real or imagined source of tiny nuggets found washed further downstream (by current or ancient no longer present water flows). In that sense, to which I'm a little wedded by practice, they don't move about, at least not until mined dry and relocated to some treasury or rich persons pocket.

Bangs and matrix are overloaded, it's hard keeping up with what others mean in their use of terms, Gammon in the UK has a meaning different to it's use by urban aboriginal people in Australia.

For some the origins of local Black Culture have little remnant of African culture and predate both the arrival of convict ships upon the tide and the retreat of ice from Europe that allowed the settlement of the extremely white bits.
