Omakorokoza (the local name for informal diamond panners/prospectors)
The hand-digging and panning of alluvial diamonds from softer Quaternary sediment deposits by informal miners, known locally as omakorokoza, in the Marange (Chiadzwa) diamond fields of eastern Zimbabwe's Manicaland province, following the fields' discovery by villagers in June 2006. Early artisanal mining specifically targeted the softer surface sediment layers using rudimentary equipment -- picks, shovels, and a metal rod ground to a sharpened point -- with prospecting expeditions typically lasting two to four weeks, during which groups carried only essential supplies: mealie-meal to cook sadza (the regional maize-porridge staple), biltong (dried meat) as an accompanying relish, drinking water, and repurposed five-litre tins used as makeshift cooking pots. Diamonds from Marange are geologically notable for their formation history, including a documented population of naturally irradiated black diamonds bearing distinctive graphite inclusions. Following the initial 2006-2008 artisanal rush -- during which the Diamond Development Initiative estimated Marange could account for a meaningful share of diamonds entering the global jewelry trade -- the sector was forcibly reorganized: in late 2008, Zimbabwean military forces were deployed to the fields, an operation documented by Human Rights Watch as involving torture, beatings, and harassment of miners, displacing the artisanal workforce and consolidating extraction under state-linked and joint-venture mining companies. Mining has since been substantially mechanized, though the Zimbabwean government has more recently signaled intent to formally allocate mining claims to local communities and artisanal miners around Marange as part of a stated community-empowerment policy.
