WE PRESENT YOU: GEOMINAS S.A.

GEOMINAS is a Colombian engineering company established in 1969 as a consulting
group specialized in Mining Engineering, Geology and Oil Industry.
During its early years GEOMINAS worked as a geotechnical consulting firm and on theevaluation of some mineral prospects for major Colombian companies. Later, it createdcore drilling and tunneling departments which made the company´s affairs to evolve
towards diverse consulting activities and bigger projects dealing with mineral resources.
Today GEOMINAS has an excellent professional staff including local and foreignassociates with vast experience in Geology, Geotechnics, Mining, and Environment
Engineering. On the evaluation of mineral sites, the company can reach levels ranging
from prefeasibility to feasibility studies, designs, construction and development, always
maintaining the highest quality standards and a rigorous pursuit for environment’s care.
GEOMINAS has practically studied every corner of the Colombian territory working forcountless clients in the mining and civil engineering projects, such as construction ofroads, tunnels, dams, urban development, etc. This valuable experience has allowed
GEOMINAS to assist the Colombian government, particularly the Bureau of Mines andEnergy, on the development of very relevant projects related to mineral economics
organization and planning and the energety development of the country.
Since GEOMINAS is intimately linked to the mining industry, it has many businessaffair opportunities relate to this primary sector of the economy.
GEOMINAS has worked for Empresas Publicas de Medellin (Colombia’s mainhydroelectric energy supplier), ISA, all the cement (concrete) Colombian companies,CERROMATOSO (nickel), INTERCOR (coal), PRODECO (coal), Carbones del Caribe(coal), Frontino Gold Mines, Mineros de Antioquia (gold), Consorcio Minero Unido(coal), Empresas Departamentales de Antioquia EADE (state company), for theBureau of Mines and Energy and the UPME (Unit of Energy and Miine Planning),
CARBOCOL and ECOCARBON (coal), TVX of Brazil (gold), CHILGENER from Chileand many other local and foreign companies which would make this list endless.
GEOMINAS has participated in specific projects with foreign companies when newtechnologies are required or when the requirements of such projects exceed thosecompanie´s capacity .
GEOMINAS is the most experienced Colombian company in coal exploration. It wasthe leader in an international partnership for the feasibility studies of the Alto San Jorge(Cordoba) and El Descanso (Cesar) coal basins, both carried out for CARBOCOL orECOCARBON (today MINERCOL) adding more than 50.000 m of core drilling. It also
drilled for INTERCOR at the Cerrejon coal basin (Guajira) nearly 18.000 m ofexploratory cores. Some other important works are: drilling for GEOMET’s gas
research in El Cerrejon coal basin; for CONSOL in the Cucuta coal basin (Norte deSantander); for NORCARBON in La Jagua de Ibirico; for Carbones Nechi at the Amaga
coal basin. These exploration works were completed mostly with the deposit geologicalmodel, the evaluation of the resources and open pit or underground mining program.
The history of GEOMINAS is heavily linked to the development of Colombian concreteindustry. Their first technical investigations with drilling, evaluation and mining project
were carried out for Cementos Diamante in Bucaramanga.

Some other projects include: drilling, evaluation and mining design of Cementos
Boyaca limestones in Nobsa and Suescun; evaluation of limestone in Sumapaz for
Cementos Boyacá; study of calcareous remains in the Apulo region (Cundinamarca)
for Cementos Diamante; drilling and evaluation of deposits of Payande (Tolima) for
Cementos Diamante; evaluation of limestone deposits for Cementos del Norte(Cúcuta); study of the limestone of Rio Claro area (Antioquia) for Cementos El Cairo,
which gave origin to the factory´s name; the exploration studies, evaluation and mining
designs of the quarry of Cementos de Caldas; recently it executed studies of evaluationof the Mulalo quarry for Cementos del Valle; the exploration studies and mining designfor the open pit of Cementos El Cairo, and later the prefeasibility underground mining,
the tunnelling excavation and the geologic consulting for the same calcareous deposit.

GEOMINAS has founded companies which are located in mining centers of greatinterest in Colombia such as Santander del Norte, El Cesar, Cundinamarca andAntioquia. Today the company is mainly focused in the business of coal mining,
operation of its and other propietor´s mines, and the commercialization of its ownproduction.
