Miwah Prospect High Sulphidation Au-Cu Mineralisation, Northern Sumatra, Indonesia
The Miwah prospect lies on the dilational 070 trending Miwah Lineament near its intersection with northerly oriented
fractures within Pliocene volcanic rocks exposed between a NW trending segment of the dextral transcurrent Sumatra
Fault, and the more northerly trending Samalanga-Sipopok Fault to the east. These faults reflect the continued
interaction between stresses from the India-Australia plate located to the southwest, and spreading within the Andaman
Sea to the north of Sumatra. A system of deep seated faults is believed to have facilitated emplacement of post-Miocene
magmas and Quaternary volcanic centres at shallow crustal levels throughout northern Sumatra.
