Odin – Altair NI 43-101 Summary

Historic Highlights

Primary engaged Derrick Stricland P.Geo to complete an initial N.I. 43-101 technical report potential Vanadium deposits. The Odin and Altair research permits applications consists of two non-surveyed contiguous applications totalling 8,550 hectares, the research permits applications are located within the province of Badajoz, of Kingdom of Spain. 


Position of the Research Permits

Odin Permit

Main data

It is located in the Badajoz province in a very famous  historic Pb-Zn-Ag district. The main geological formation is the weathered paleozoic shales with a clayey appearance on the surface and dark blue in depth. The general direction of the pinchers is to the NO. introducing some interstratified dykes of basic rocks. Crossing this area there is a formation of veins in which lead minerals predominate, which have been exploited since the most remote times. Within the same formation and occupying the higher parts of thick veins, vanadium minerals are found which have also been exploited, although not on a large scale. The exploited mineral is vanadinite or clorovanadate of lead, associated with lead carbonates and blend.

In the area of Azuaga, there are references of having been found vanadium in the lead mines giving grades of 7% of V205

Altair Permit

Main data

The Altair permit is located adjacent to the Odin permit in the NW. The geology is exactly the same like in Odin with weathered paleozoic shales with a clayey appearance on the surface and dark blue in depth. The general direction of the pinchers is to the NO. introducing some interstratified dykes of basic rocks. Crossing this area there is a formation of veins in which lead minerals predominate, which have been exploited since the most remote times. Within the same formation and occupying the higher parts of thick veins, vanadium minerals are found which have also been exploited, although not on a large scale. The exploited mineral is vanadinite or clorovanadate of lead, associated with lead carbonates and blend.

In the area of Azuaga, there are references of having been found vanadium in the lead mines giving grades of 7% of V205.

Odin – Altair Regional Geology

The Badajoz province is the unique región of Spain where the vanadium were extracted at industrial scale. During the first years of the XX century, the production was a world class deposit in terms of production. The vanadite apears in dikes with NE-SW direction an it is asociated with cerusite and blend, calcite and iron oxides. The vanadite comes from the alteration of the blend, having been the vanadium its origin in the host rock amphibolites.

The most relevant old mines were “San Miguel”, “Joaquina” and “Gerty” and that correspond to mineralizations of secondary origin, supergenic, of vanadates of Pb that in depth pass to filonian mineralizations of type BPG. They fit in the amphibolites of the Neissic succession (Neises de Azuaga) and their origin would be related to a high V content of these rocks, which under supergenic conditions will be remobilized (a, later fixing on the Pb seams. Thus, these mineralizations constitute the gossan of the BPG type reefs when they host into amphibolites. The mines were closed for the low prices and weak demand.

Some authors have suggested a late Variscan age related to the waning stages of peri-magmatic hydrothermal systems (Concha et al., 1992; Lillo et al., 1992). Such a hypothesis is plausible for some vein fields characterized by a zonal peri-batholithic arrangement with intra-plutonic copper veins and zonally arranged Pb-Zn and Sb lodes, as in some areas of the Los Pedroches batholith (Ovtrach and Tamain, 1977).

Veins are reported to be (<200 m in length), subvertical and oblique to the strike of the shear zone, with north-south and northeast-southwest trends, and they are almost always hosted by the most brittle rocks (gneisses, amphibolites, and ultra-mylonites) or the shales of the Azuaga Formation. The veins are particularly abundant and sulfide rich near the late Variscan Santa Marta granodiorite (Tornos et al., 2004). The hydrothermal fluids were low-temperature (ca. 200°C), boiling, low-salinity, aqueous fluids (Chacón et al., 1981). Post-Variscan Pb-Zn veins spatially associated with the Badajoz-Córdoba shear zone. Most of them show no obvious relationships with Variscan granitoids. The veins are usually related to Variscan granitoids (granodiorites to monzogranites), occurring both inside and peripheral to them.

The Primary Cobalt Corp. is exploring for vanadium, particularly vanadate of lead zinc. Vanadates of lead, zinc, and copper (vanadinite and minerals of the descloizite-mottramite series) form in the oxidized zones of base-metal deposits, especially in areas of arid climate and deep oxidation (Fischer, 1975).

Vanadate minerals and wulfenite (a lead molybdate mineral) within these deposits form crusts on open cavities or are intergrown with residual clays (Fischer, 1975). The vanadate ores in the Otavi Mountainland occur in collapse breccias and solution cavities related to karst development in Neoproterozoic carbonate rocks of the Otavi Supergroup and are spatially associated with primary sulfide orebodies within the carbonate strata (Boni and others, 2007).

Mottramite and copper descloizite are particularly abundant around copper sulfide deposits (Tsumeb type), whereas descloizite occurs in areas surrounding primary sphalerite-willemite (a zinc silicate mineral) orebodies (Berg Aukas type).

There are five historical producing lead (Pb) mines from the early 19th century on the current configuration of the Odin and Altair research permit applications. These include the Gerty, Chaparral, Joaquina Arroyo Conejon, and Chocolata and Chaparal.

The Gerty mine was reported to be in intermittent production for lead and Vanadium from 1928 until 1942. Due to the well periodic flooding, excavation was carried out by a trench above water level in the southwestern part of the operating area. A reported 70 tons of vanadium concentrates were extracted with an average of 10-12% V2O5. In 1949 the water level reached only 7 metres from the surface, flooding most work both underground and surface. Underground workings are currently sealed and inaccessible, and the trench is almost completely filled.

In 1940 there was a reported 18 tons of galena with a reported grade of 5.2% vanadium produced. There are reported workings up to 90 metres underground with three main levels at 40, 70 and 90 metres with adit lengths of 190, 110, and 70 metres respectively. The reported mineralogy from the productions vanadinite, galena and lead carbonates with clay, calcite and iron oxides.

Joaquina Mine, where modern lead workings began around 1863. Specifically, between 1908 and in 1912, Joaquina maintained a production of about 2,500 tons lead annually. The reported depth of was 310 metres.

At the Arroyo Conejon mine indications of vanadium are also found in the tailings. These mines were exploited for lead by the Eagles Company since the late 19th century shortly before the first European war. Taken a sample of the dump, in which the presence is sometimes observed of abundant pyrite and analyzed has given 0.50% V205 and 4.81% Pb.

At the Chaparral Group Mines, vanadinite microcrystals have been found, of a greenish brown color, in a small tailings pile which is part of the mining group "El Chaparral”.
