It discusses the social and economic relations in the current City of Itapu? do Oeste and the Jamari National Forest area, in the period that includes the mid 50s until the late 90s of XX century. During this period cassiterite comes to occupy a prominent place in the local economy since the rubber loses its economic importance in the region and its value in the international market. The end of manual mining in 1971 attracted for the region national companies and multinational groups, which changed some aspects of mineral exploration and working relationships in order to make them more human than they were in the days of the rubber and later of the mines. With the emergence of Itapu? do Oeste in the late 70 the differences between Itapu? do Oeste and the Jacund? Mining are immense in terms of the basic structures of care for the population, such as sanitation, prevention of endemic diseases, public lighting, education, etc. But with the breakdown of cassiterite in 1989/1990 in the international market, the cassiterite mining underwent a process of adaptation to the new reality imposed by the market, so a significant part of the population of Jacund? Mining that has not been fired began to settle in the Itapu? do Oeste at a time when the district Itapu? do Oeste is elevated to municipality. / O presente trabalho ? o fruto, de pelo menos, dez anos de pesquisa desde a elabora??o do projeto, a primeira entrevista e os primeiros documentos catalogados no Centro de Documenta??o Hist?rica do Tribunal de Justi?a de Rond?nia. Trata sobre as rela??es sociais e econ?micas na ?rea do atual Munic?pio de Itapu? do Oeste e da Floresta Nacional do Jamari, no per?odo que compreende meados dos anos 50 at? o final da d?cada de 90 do s?culo XX. Nesse per?odo a cassiterita passa a ocupar lugar de destaque na economia local, j? que a borracha perde sua import?ncia econ?mica na regi?o e seu valor no mercado internacional. O fim do garimpo manual em 1971 atraiu para a regi?o empresas nacionais e grupos multinacionais, que mudaram alguns aspectos da explora??o mineral e as rela??es de trabalho, de modo a torn?-las mais humanas do que eram nos tempos dos seringais e posteriormente dos garimpos. Com o surgimento do povoado de Itapu? do Oeste no final dos anos 70 as diferen?as entre Itapu? do Oeste e a Minera??o Jacund? s?o imensas do ponto de vista das estruturas b?sicas de atendimento ? sua popula??o, tais como: saneamento b?sico, preven??o ?s doen?as end?micas, ilumina??o p?blica, educa??o, etc. Por?m, com a quebra da cassiterita entre 1989/1990, no mercado internacional, a minera??o de cassiterita viveu um processo de adapta??o ? nova realidade imposta pelo mercado, assim uma parte significativa da popula??o da Minera??o Jacund? que n?o foi demitida passou a fixar resid?ncia no distrito de Itapu? do Oeste em um momento que o distrito ? elevado ? condi??o de Munic?pio.
