Octávio Barbosa received numerous accolades, awards and honors. In 1974 he received the Medal of Merit Mineral. The Brazilian Geological Society (SBG) in 1968, awarded him the highest honor of geologists from Brazil, the Gold Medal "José Bonifácio." He stated several times that the professional to feel happy to follow their desires and meet up with their aspirations and their work. Feeling comfortable in improvisations Mandatory field work and having used all means of transport that can be imagined as jeep, airplane, little planes, helicopter, mule, truck, boat and how many types of locomotion may exist , Octávio Barbosa always preached to the young:Love life of the field and like to travel, by any possible means of locomotion'. His love of geology made him declare often that will live with a hammer in his hand until the last day of his life.

" Much remains to be done, geology and mining in Brazil. Although the current labor market and demand for services to geology are still very scarce, I believe (says Octávio Barbosa) that this situation will change because in large countries such as South Africa, Canada, the United States, Russia and others, where the geology was well developed, still discover new things. In spite of all that is known, is a world to discover . The Amazon, for example, which is unknown, is a true Canadian. Therefore, I believe there will, therefore, an incentive for the present, even the new geologists, come here to toil in their specialties"' "- Octávio Barbosa.
