I mean, 1980 Zambia is literally apartheid era. That's a statement of fact.
You don't like the associations that "apartheid" evokes? And yet, for an emerald mine in Zambia, apartheid was certainly a big factor in the working conditions there. The mines in Zambia (mostly copper) benefited the most by apartheid, where white workers were paid over ten times what black workers were paid. Even during the 80s, when supposedly the color bar had been dismantled, mines got around that be defining all black labor as "local" (even if the workers were immigrants) and white workers as "skilled expats" (even if the whites were born next door). [1]
Mining, indeed, was heavily tied to the apartheid from the very start. [2]
So it's very relevant that it's an "apartheid era." You could not invest in a mine in Zambia or South Africa without knowing that you were investing into a apartheid system, and hoping to make money off the backs of the apartheid abuses.

Yes, I agreed that that wasn't backed by known evidence in my statement above.
