Rory's Knoll mineralization 1 g/t Au cut off grade
The Rory’s Knoll deposit extends ±250
m along a trend of 300º W, plunges ±70° N, and
dips 80° to 85° E. It is about 100 m thick at the widest
point and has been traced to about 1400 m below surface.

Host rocks are interbedded volcanic flows, tuffs
and graywackes intruded by granitic and QFP dykes in a ductile
(?) deformation zone between a hanging wall sequence of volcanic
rocks and a footwall sequence of volcanic and sedimentary rocks.
Superimposed on the deformed rocks is intense wallrock alteration,
which was divided during core logging into: 1.) “Dacite
Tuff”, 2.) “Sericite Schist” and 3.) “Altered
Volcanic Rock”. The three units are complex mixtures of
different lithologies, and different types of deformation with
different superimposed alterations and veining. Gold mineralization
is spatially associated with the “Dacite Tuff” unit.
Petrographic work (Kipfel, 2005) indicates most
wallrock alteration is carbonate, sericite and quartz. The “Dacite
Tuff” unit has been named by Kipfel as tonalite. The mineralized
zone contains disseminated pyrite grains as well as minor amounts
of chalcopyrite and molybdenite. Trace amounts of sphalerite,
argentite, native silver, bornite and chalcocite have been reported
in polished sections. The gold mineralization is at reasonably
consistent grades through large volumes of rock which indicates
fine evenly distributed gold grains.
In the hanging wall, narrow zones of quartz breccias
surrounded by envelopes of carbonatization and pyritization contain
significant amounts of gold mineralization. In the footwall, there
are narrow quartz vein stockworks with pyrite and gold.
