What caught my eye is that the caption labels it "East African chromite," which is probably incorrect. The chromite was almost certainly mined in Zimbabwe, in open pits in Shurugwi (then Selukwe) and then shipped to Britain via Beira.

Chief Kapijimpanga worked with the prospecting party that established a mine at Kansanshi in the 1900s and the film includes footage of the remains of that mine in the early 1970s. I think has now been obliterated by the new open pit.
Scholars in Zambia (and anyone else) can now consult the physical archive with permission of the Mineworkers' Union. The archive is stored at the union's head office: Katilungu House, Obote Avenue, Kitwe.

I chaired a talk by van Onselen on the book earlier this year and he used this inhuman system of transportation to make an argument about moral judgement in history and the critique made of judging historical actors by contemporary standards.

There's a great museum and a reconstruction of 19th century Kimberley around the hole, but I don't think they appreciate the significance of some of the stuff in this museum.
I'm supposed to nominate someone else but I'm pretty sure everyone else did this last year.
