01 · Regional setting

The intersection of two mineralized trends

The concession sits where two regional mineralized trends converge, along an 11 km mineralized strike ringed by historical mines and prospects. Berlin, Toledo, El Valle, La Merced, Valdivia and San Andrés all lie on the same structural corridor.

Two trends converge

The project is centred on the intersection of two mineralized trends — the structural setting that concentrated historic production along this corridor.

11 km strike

A continuous 11 km mineralized strike is mapped through the licence area, with multiple historical workings along its length.

Power on the doorstep

The Ituango hydroelectric plant — 2,400 MW at a US$5.51 billion estimated cost — sits immediately west of the concession.
