Abstract
The extraction of gold from placer deposits was the first mining activity developed in Cuba. In past decades, resources were invested in geological investigations for this type of deposits distributed in sediments of different genesis that are not exploited. As a research methodology, proceeded to rescue the primary field materials in different formats, their reports, articles, as well as the information obtained by the authors in field visits and interviews at current extraction sites. The interpretation - generalization of the information made it possible to detect methodological deficiencies in regional studies regarding the selection and taking of samples, as well as the lack of attention to studies developed by the IGP. Considering their distribution, dimensions, characteristics and sizes of the gold particles, the sources of contribution are classified into three large groups related to sediments of the: Northern Ophiolitic Belt, Cretaceous Volcanic Arc and the Passive Continental Margin. It is recommended to draw up a strategy that allows to resume the methodological works, verification - evaluation of a group of these deposits, in the Havana - Matanzas, Central and NW of Holguín regions. It is concluded that the pleasures could be attractive for the small national mining given the gold prices, the low costs and low complexity for the installation, transfer of the equipment for the exploitation and the need to increase the exports.
