IRON ORE
Our odyssey in Peru started in 2011 with Iron Ore as the principal objective. Since 2011, we have conducted numerous explorations and have had several teams of geologists conduct surveys across the length and breadth of Peru. From the Northern district of Piura to the Southern borders of Tacna, our geological teams have conducted detailed surveys and created an “Iron Ore Map” of various deposits and their feasibility. Our primary areas of interest are ores that would qualify as Direct Shipping Ores (DSO) with a minimum grade of 56% Fe.
NORTHERN CLUSTER
Magnetite veins observed in the northern cluster represents porphyry styled mineralization, accompanied by sulphidic alteration in the wall rocks. Associated with magnetite are hematite, goethite and chlorite in minor quantities. Major structural control is predominantly along 300 degree trends. In the pit areas rock formations are generally hard and magnetite veins expose out on a moderate 30 degree slope. This indicates a relatively shallow plunge of the vein and pit slopes are expected to be stable. Currently observed mineralization indicates a stretch of 1000m strike extension in and around the northern cluster. Observed width of mineralization in the pit area is 10m, which is a measure for selective mining and may vary to a great extent depending upon the local geology.
Various sampling done in the regions gave average values as follows –
Fe % - 58.0 - 63.0
FeO % - 1.1 – 2.88
Fe2O3 % - 80.7 – 88.88
Al2O3 % - 3.08 – 8.98
S % - 0.04 – 0.11
SiO2 % - 1.38 – 8.93

PUNO CLUSTER
The Puno Cluster mainly consists of DSO Iron Ore of extremely high grades. These deposits are mainly on the surface and consist of coarse grain magnetite of a skarn nature. Mineralization comprises large, sub-horizontal areas of intense iron oxide (magnetite and hematite) developed in metasomatized Ferrobamba Formation. Hematite and magnetite are common in most deposits, and the presence of dolomitic wall rocks is coincident with massive magnetite lodes.
Some skarns have a significant geophysical response. Almost all skarns are significantly denser than the surrounding rock and therefore may form a gravitational anomaly or seismic discontinuity. This is particularly evident in some of the large iron skarns which may contain more than a billion tonnes of magnetite (specific gravity 5.18). In addition, both skarns and associated plutons form magnetic anomalies.
Various sampling done from the regions gave average values as follows -
Iron (Fe)% - 59.00 - 67.00
Silica (SiO2)% - 1.56 - 3.27
Alumina (AI203)% - 0.60 - 1.10
Phosphorus (P)% - 0.05 - 0.10
Sulphur (S)% - 0.09 - 0.15
