The lack of in depth knowledge on the nature and origin of the gold bearing formations in the South Abu Marawat region at the central part of the Golden Triangle Fig 1b c the most potential
Testing a rock for gold using magnetism is simple because gold is not attracted to magnets unlike pyrite which is magnetic due to its iron content This method involves using a strong magnet like a rare earth magnet from a hardware store to see if the rock reacts While magnetism can indicate the presence of pyrite it doesn t rule out
most prolific gold resource in Venezuela Mineralization is hosted by a vein system that is genetically associated with the El Callao transpressional shear zone This vein system consists of a network of interconnected quartz albite ankerite veins enveloping a large number of metabasaltic fragments that host gold bearing pyrites
