Significant mineralization, up to 20% stringers, disseminated and semi-massive to massive sulphides, was intercepted in 7 of the 8 drill holes within the first 20 metres from surface which was contained in altered volcaniclastic rock
. The mineralized intercepts range from .5 metres to 8.7 metres which are within broader altered zones consistent with the VMS deposit formation process.
All intercepts were present within zones of pyrite and quartz veins in the volcaniclastic rock
. Ground geophysics (induced polarization, IP) suggests the SE-trending structure terminates south of OURC029, and is offset either 90 m to the northeast, or 240 m to the southwest.
The ophiolitic and volcaniclastic rocks
in the Wazhdad area and its vicinity show soapstone mineralizations.
The pyroclastic rocks are volcaniclastic rocks
formed by accumulation of pyroclasts (fragments) during Mesozoic explosive eruption by Yanshan movement.
The rocks along the Tarom-Hashtjin axis, which are considered equivalent to the Karaj Formation, are different from those in central Alborz in terms of the lithology and chemical composition because the lava flows do not consist only of volcaniclastic rocks
along this axis and their compositions are more basic.
Permo-Triassic and Cenozoic sedimentary, volcanic and volcaniclastic rocks
unconformably overlie the Palaeozoic basement (Fig.
Muehlenbachs (2003), "Tuff Life: Bioalteration in volcaniclastic Rocks
from the Ontong Java Plateau," Geochem.
The Corralitos area is underlain by hydrothermally-altered, coarse-grained granodioritic to monzonitic intrusions and adjacent volcanic and volcaniclastic rocks
of probable Cretaceous age.
The Property is principally underlain by Tertiary volcaniclastic rocks
of the Callipuy Formation.
This resource consists of two mineralised bodies, the Main Zone and Tom's Zone in Silurian volcaniclastic rocks
of the Anson Formation.
