I’m seeing different information regarding the Date of Discovery and Discoverer between  and . From what I can tell so far, it seems that the skull/fragments of the skull were discovered in 1925 by Kenneth Kemp, who then gave it/them to J. G. van Alphen who then donated them to the McGregor Museum in 1929.
The CK remains, comprising fragments of a human cranium, were discovered by a diamond digger named Kenneth Kemp and passed to J.G. van Alphen, ‘magistrate, writer and fossil collector’, who presented them to the McGregor Museum.
This document supports the claim that the initial discoverer was Kenneth Kemp, yet it also says that the date of discovery was 1929.
…Curiously, he also refers to ‘some fragments of limb bones’ found with the skull, but did not describe them and they are not mentioned in the museum’s 1929 accession record (MMK 215: ‘Skull [incomplete]’).

re: Geological Age
…Several other isolated and variably mineralized specimens, such as the fragmentary cranium from Canteen Kopje, South Africa at one time regarded as being of MSA antiquity (Broom 1929b), are likely to be of recent derivation, although their absolute ages cannot be determined at present (Smith et al. 2012). These specimens have rightly fallen into obscurity.
