Deposit Type

  • Laterite


Summary:

Bicholim-Sirigao deposit is the best deposit of Goa state. It is situated between Bicholim in the south-east and Sirigao in the north-west. The deposit occurs oa a N 50-60o W trending anticlinal fold, overturned to the south-west and its nose portion refolded in shape of 'S' with a plunge of about 22-27o towards N 60o W. The southern limb of the fold extends for a length of about 4km from Bicholim-Piligao road in the south-east to about 500m north-east of Sirigao hill while the northern limb extends for a length of about 2km from Bordem in the south-east to about 500m north-east of Sirigao hill. Between the two limbs of the anticlinal fold, which are ore-bearing, there is a barren phyllitic tract which represents the axial portion of the fold.

The deposit consists of two orebodies, a larger south-western one and a smaller north-eastern. The total length of the south-western body between Bicholim-Piligao to Sirigao hill is about 6.25km and the windth varies from 70m to 550m. The north-eastern orebody is about 1.25km in length and the windth varies from 115m to 140m. Both these orebodies are thoroughly explored by drilling and proved up hte bottom.

As regards the quality of ore, the best grade of ore in south-eastern orebody is present in the section between Lamgao and Sirigao hill. Here, the Fe content lumpy ore ranges from 60 to 63 percent and in powdery ore from 64 to 66 percent. In Seltom Mosque hill area, the lumpy ore contains 57 to 59 percent Fe a ........
