Abstract:Agriculture has always been the major source of income of the Republic of Haiti. Only in the late sixties did the Haitian Government decide to move toward industrialization and explotation of natural resources, but no reliable inventory of mineral potential was available. In June 1970 the Resources and Transport Division of the U.N. (now CNRET) undertook a structural analysis of the Caribbean with reference to defining favorable loci for ore disposition. One of the conclusions of this survey was that from the metallogenetic point of view, the Northern part of Haiti was a favorable area for prospecting for habe metal deposits, especially for copper. Those conclusions were acknowleadged with great enthusiams by the Haitian authorities, and they welcomed in July 1971 a UN technical adviser who outlined a first phase of exploration. Following this mission, a “Mineral exploration Project” was created by the Haitian Government with the cooperation of UNDP, and an area of 9000 km2 was selected, based on structural, lithological, and metallogenetic reasons, as an exploration target. The most important aspects of this project were:Mineral Exploration—First Phase (1973–1974). The following operations were carried out by a small team: (a) photo interpretation at 1:50,000 and 1:200,000 scale, (b) geological reconnaissance at 1:50,000 scale, (c) geochemical reconnaissance (stream sediment) at 1:50,000 scale. The photo interpretation helped outline zones of particular structural interest and was followed up by ground control studies. Stream sediment geochemical reconnaissance was carried out over half of the project area, following the indications given by the photo geological interpretation. finally, combining all the data, five areas were selected for detailed follow up survey: (1) Terrier Rouge—Perche, (2) Vallieres, (3) Mont-Organise, (4) Limonade, (5) Gros Morne—Le Borgne.Mineral Exploration—Second Phase (1975–1976). The main zones of interest were reduced to a few hundred km2 and porphyry copper type deposits appeared to be the most promising target. Detailed geological mapping (1:25,000 to 1:2,000) and soil geochemistry were carried out on the above mentioned five areas, the most promising appearing quickly to be Terrier Rouge-Perges, with porphyry-type copper mineralization. A geophysical survey (IP and Mag) confirmed the geochemical results. At the end of the second phase of exploration (December 1976) two of the five prospects of the Terrier Rouge area have been diamond drilled and appeared to be of potential economic interest. Because of the number and importance of the prospects discovered a third phase of exploration was deemed necessary with the purpose of continuing the detailed prospection work and drilling the other prospects. This third phase started in January 1977 and was expected to last until December 1979. This paper was presented at the International Geological Correlation Program (IGCP) Project 98: “Standards for Computer Applications in Resource Studies” held at Taita Hills, Kenya, November 8–15, 1977.
