Epithermal vertical metal model
At Stanley's Hope and at various locations within the Pentland JV we have
mineralised structures which are interpreted to be high level, concealing the
precious metal zone at depth.
Due to quartz textures, high volatile content (ie Mercury Hg and Antimony
Sb) and mineralogy, highly altered clay species common at shallow levels,
CYU will test in the concealed blue depth band of at least 80m depth vertical
to intercept economic values at Stanley's Hope. These kind of systems can
be company makers. This is not narrow vein style but epithermal quartz filled
structures.
This diagram was modified from Hedenquist et al (1996) and was applied to
the Palmarejo Project in Mexico where current CYU Management previously
worked for the Bolnisi NL company and defined a concealed system in 2004.
