Abell 3667 is among the most well-studied galaxy clusters in the SouthernHemisphere. It is known to host two giant radio relics and a head-tail radiogalaxy as the brightest cluster galaxy. Recent work has suggested theadditional presence of a bridge of diffuse synchrotron emission connecting theNorth-Western radio relic with the cluster centre. In this work, we presentfull-polarization observations of Abell 3667 conducted with the Karoo ArrayTelescope at 1.33 and 1.82 GHz. Our results show both radio relics as well asthe brightest cluster galaxy. We use ancillary higher-resolution data tosubtract the emission from this galaxy, revealing a localised excess, which wetentatively identify as a radio mini-halo. This mini-halo candidate has anintegrated flux density of $67.2\pm4.9$ mJy beam$^{-1}$ at 1.37 GHz,corresponding to a radio power of P$_{\rm{1.4\,GHz}}=4.28\pm0.31\times10^{23}$W Hz$^{-1}$, consistent with established trends in mini-halo power scaling.
