Artists Representation of Witwatersrand Reefs During Deposition

This diagram is from a really interesting book about the history of the Witwatersrand goldfields in South Africa (ISBN 0 620 09663 2). It helped me to visualize what occurred at Pardo as well. Gold is concentrated along the banks of those channels, one can imagine the distribution of gold is complex as the position of channels changes over time. Finding and following "pay streaks" is how the South African miners developed the Wits.
