Gold and silver production in Honduras probably never exceeded 5% of that produced in Spanish America at any one time during the colonial period, but it was of considerable importance to the local economy and employed a significant proportion of the total workforce. In Spanish America as a whole the types of labour that were employed in mining were extremely varied. During the early Conquest period Indian slaves were used to pan gold in the Antilles, and later Mexican silver mining relied on the employment of free labour supplemented by that of Indian and Negro slaves. In Colombia the repartimiento provided Indians for mining up to 1729, by which time the Indian population and gold production had declined, but in Peru the mita continued to supply labour for the mines until its abolition in 1812, although by that time the mines had become heavily dependent on free labour. The dominant type of labour employed in mining in any one area at any one time appears to have been strongly influenced by the availability of Indian labour, which was largely determined by the size of the Indian population and the number of competing demands for labour, and by the profitability of mining, which determined the ability of miners to overcome shortages of labour. These influences were very apparent in the mining industry in Honduras, where during the colonial period many different types of labour were employed: Indian slaves, Indians working in the service of encomenderos, Negro slaves, Spanish immigrant workers, Indians working under the repartimiento and free labourers.
