Rory's Knoll

Highlights: Recent initial resource estimate showing

  • 1.33 Million ounces Indicated @ 2.84 g/t Au.
  • 2.38 Million ounces Inferred @ 2.92 g/t Au.

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.
