Application to exploration


The Botafogo Project is 100% owned by AHP Lda. it is in the process of signing the formal Contract of rights, and is located in the Southern Region of Portugal, covers 492km2 in the Elvas Municipality – Portalegre District.

The  Application proposal defines 350.000€ for the initial period of evaluation of 3 years, with the option of an additional extension of 2 years with an additional investment of 650.000€.

The Bota Fogo area in located at the Ossa Morena Zone, a complex geodynamic zone with diverse geologic settings that favour the occurrence of various ore forming systems and abundant mineral deposits, such as the “Olivenza-Monasterio-Campo Maior-Crato anticline” that hosts the Cu-Fe-Au mineralization of Cambrian Age, and ultrabasic and felsic massifs of Paleozioc Age.

In the area is possible to identify more than 20 occurrences including Cu,Fe, Pb and Zneveral historical documents from SFM (60´s and 70´s) and from Outokumpu in the late 90´s are available at LNEG for review or purchase.

Some of the work completed by previous operators, includes Cu, Zn and Pb geochemistry, Magnetometry, Induced Polarization, Gravimetry and Analysis of heavy mineral concentrates.

Pb-Zn – Olival das Freiras, Tapada do Olival, Cabeço da Oliveira, Tapada da Saúde, Mina da Herdade dos Mortais, Mina da Herdade da Horta Nova and Varche.

Mostly described as epigenetic metamorphic mineralization of Pb and Zn in veins and dikes up to 1.3m wide, mostly subvertical, hosted by limestones with iron. “Cabeço da Oliveira” is noted as well mineralized. Some skarn like rocks with dissemination of Pb and Zn are reported in (Varche). Assay results from the historical works are not available in the databases.

Cu – Mina de S. Rafael e Barrocal, Mina da Herdade das Caldeiras, Urmos, Mina da Herdade dos Pereiros, Mina da Serra das Correias, Mina da Amada, Mina de Barbude (Barbudos), Mina de Valbom and Mina de S. Lourenço, Barrinho, Mina da Torna do Monte de Vila Fernando and Mina de Vila Fernando.

The occurrences are related to igneous intrusions with evidences of supergenic enrichment in Cu. Host rocks are mostly metamorphized carbonated rocks  and other metasediments of more pelitic origin. Hydrothermal veins and disseminated are the common Styles of mineralization, some reported with up to 300m in strike.

Fe – Mina Tere, Mina do Cerro do Carapeto, Alagada (Porto Xico),  Enxara, Armadas (Herdade das Casas Velhas), Quinta de Santo António, Casas Velhas, Geberela (Gebarela), Barcamundis and Degola.

Usually in the form of lenses with magnetite, iron oxides, pyrite and pyrrotite, some related to skarn like rocks of Cambrian age, and locally containing scheelite. One breccia is reported at Quinta de Santo António with magnetite as cement, with Fe up to 43.6%.

Mo – BarbacenaUp in the North, closer to the contact with the granite, is reported a Mo vein with 10cm, hosted by hornfels.

From 2003 to 2005 Rio Narcea group completed a drilling campaign. PLV1, 2 and 4 focused an area with potential for sulfide mineralization rich in Ni and PLV3 and 5 focused an area with high values of Ni and Cu in floats of gossan:


Ni up to 1548ppm (158.41-159.6m)

Cu up to 900ppm (62.9 – 77.0m)


Ni up to 1216ppm (207.0-236.0m)

Cu up to 226ppm (109.0-126.0m)


Ni up to 1573ppm (86.0-92.7m)

Cu up to 1808ppm (90.4-91.4m)


Ni up to 974ppm (108.0 – 110.0m)

Cu up to 80ppm (108.0 – 110.0m)


Ni up to 3189ppm (43.0-45.0m)

Cu up to 2400ppm (43.0-45.0m)
