In a short period of time, Northern Lion has assembled an impressive package of land, (some 600 square kilometres) within two licence blocks in highly-prospective areas of Portugal: Cercal, located in the Iberian Pyrite Belt, and Moura, located in central Portugal."
click to enlarge | The Iberian Pyrite Belt ("IPB") of Portugal and Spain comprises Late Devonian to Middle Carboniferous sedimentary and volcanic rocks and is 250 km long by 25 to 70 km wide. It has been actively mined for over 2,000 years and hosts some of the world's richest (e.g. Neves Corvo) and largest (e.g. Rio Tinto - 335 million tones ("Mt") and Aljustrel - more than 270 Mt) volcanic-hosted massive sulphide ("VHMS") deposits.

In all, some 88 deposits are known in the Iberian Pyrite Belt ("IPB"), containing more than 1,725 Mt (previously mined and present reserves) grading 1.30% copper, 0.70% lead, 2.00% zinc, 0.50 g/t gold and 26 g/t silver. These deposits include seven that are classed as "giant", each containing more than 100 Mt. The IPB dwarfs the world's other large volcanic-hosted massive sulphide ("VHMS") provinces, such as Canada's Abitibi Belt 478 Mt) and the Bathurst Camp (252 Mt), and Sweden's Skellefte District (161 Mt).
