On 1 January 1948, 'Club Social Deportivo Deportes El Loa' was founded in Calama, Chile. This club was the first legal personality of the team and the first team in Calama in have this type of personality. In 1951, the team played in the Asociación de Fútbol de Calama with a second team with the name 'Cóndor'. Later, in February 1955, the team was renamed to 'Club Deportivo y Social Sport Cóndor.

In 1957, Calama entered on a tournament organized by the newly established Asociación Nacional de Fútbol Amateur de Chile, previously known as a federation, Calama had participated in previous amateur tournaments, such as in 1949 and 1953. The third Nacional Juvenil de Fútbol began on 28 July of that year. The organizers' goal was to select a group of players who would compete in the 1962 World Cup, which would be held in Chile. The first phase matches were played in regional divisions, with the Calama youth team facing off against its counterpart from Chuquicamata.

In 1959, the Calama Amateur team, coached by Roberto Rodríguez Antequera, won the 28th edition of the National Amateur Football Championship. The final was against Thomas Bata de Peñaflor, played at the Estadio Municipal de Calama. The score was 3–2 in extra time, after a 2–2 tie at the end of regulation time. The game-winner was scored by Valencia in the 8th minute of the first half. The team that played in the final was as follows:

Hidalgo, Soto, Tapia, Lillo, Aracena, Toro, Gutierrez, A. Portillo, Valencia, M. Portillo, and Vega.

This achievement allowed Calama to qualify for the Copa Chile of that same year, as an amateur team, but they only reached the round of 16 of the tournament, being eliminated in that round by Deportes La Serena, winning by one goal in the first leg and winning 6–0 in the second leg, qualifying them for the next phase.

By 1960, Sport Cóndor team was already participating in provincial championships in the region of Antofagasta with teams from Calama, such as Tronador, which would animate the matches of the Asociación de Fútbol de Calama of that decade; from Tocopilla as Chile Sporting, from Tal-Tal as Unión Caleta and the teams such Coquimbo and Correvuela from Chuquicamata.

Later, on Sunday, 17 December 1961, the Chuquicamata amateur, coached by Daniel Chirinos, team won the next edition of the Chilean National Amateur Football Tournament undefeated against Osorno 3–2, with a hat trick by Mario Valencia, at the Anaconda Stadium in Chuquicamata, before an audience of 6,346. The winning team's lineup was as follows:

Hidalgo, Silva, Gary, Cortés, Valencia, Reyes, León (Cortés), Portillo, Mario Valencia, Carvajal (Diaz), and Bustos.

In the previous match, the Calama teams, coached this time by Jaime Meneses, and Peñaflor played, and the score ended in a 2–2 draw. These facts pushed to the 'El Loa' citizen the desire to have a professional team in the city.

Sport Cóndor has among its accolades the local championships of the Asociación de Calama, for 1961 and 1962.

In 1962, Sport Cóndor submitted its bid to participate in professional football. At that time, the club had the support of the Chile Exploration Company, then managed by the Anaconda Copper consortium, an international mining company, from which the state-owned company, CODELCO, would be born a decade later. Its then president, Carlos Seguel, was also the company's commercial manager and established links between the sports club and the company. The Asociación Central de Fútbol Profesional de Chile responded negatively to the request by the president of the club.

During the Holy Week period of 1964, the Calama and Chuquicamata teams played an international quadrangular, hosted in Calama, with a title in dispute, which included the participation of the Municipal de Lima international team from Peru and the Universidad Católica de Chile team, who were on tour. In the last matches of the competition, the Universidad Católica team defeated the Calama football team by 4 goals to 0, in favor of the Santiago team, the goals were scored by Foulijoux, Tobar, Gajardo and Isella. And the Municipal de Lima team defeated the Chuquicamata team by 5 goals to 1, with double goals by Etuchi, Drago Mosquera and Bernales, these results gave the winner of the international tournament to the Peruvian team Municipal de Lima.

In 1965, the Presidents' Congress of the Segunda División Tournament agreed that provincial teams would not be accepted into the tournament in order to compete in 1966. Therefore, the Sport Condor club was not eligible to apply to join the Segunda División during this period of time.
