As an addendum to the above article from Wits CSMI, it is worth noting that a current debate is taking place in the press about whether Lonmin has lived up, 4 years on from the terrible events at Marikana, to its commitment to build decent homes for Marikana workers' families.

Amnesty International's view that this commitment has not been kept to is reported online at various locations, including at:

Lonmin's response (rebuttal) to this criticism is published at:

This is a live and current debate happening now.

Also noteworthy is that the recent local elections for the district where the Karee (Marikana) mine is located, representing a big reverse for the ANC governing party there:

"the ruling party has won 75.9% of the votes in Ward 31, which incorporates Marikana's Karee Mine where 44 people - including 34 miners who were shot and killed during a wage-related strike in August 2012 - lost their lives.

The EFF came in second, winning 17.98% of the votes, while the African Independent Congress came in third with 2.33% of the votes.

In Marikana's Ward 32, the DA was leading with 36.01% of the votes, while the ANC was coming in a close second with 32.04%. The EFF had won 19.94% of the votes in the area."
