PROPERTY GEOLOGY
The Tannahill project is underlain by a wide sequence of calc-alkaline flows of predominantly basaltic and andesitic composition. The flows are generally massive, pillowed, or flow brecciated. Locally the flows are massive with a crystalline texture, which resembles a gabbroic intrusion. A large coarse grained syenite intrusion is situatedinthesouthernportionoftheproject. Anumberofnarrowsyenitedykesradiate outwards from this intrusion, crosscutting stratigraphy. The syenite intrusion and the associated dykes are strongly magnetic and provide the only magnetic contrast in the volcanic sequence.
Drilling to date on the Tannahill Gold Zone has identified two parallel highly prospective north dipping gold bearing structures (2nd order structures) related to a large vertical structure(1storderstructure). Thegoldbearingstructures(LowerZoneandUpperZone), consist of pervasive quartz-carbonate-albite alteration with S-10% disseminated pyrite withvariablequartzveining.

Three holes below the 75 metre level along 100 metres of strike length have excellent widths with high gold grades ( 5.16 gm/t 15.0 metres in T-96-9, 4.80 gm/t / 5.00 metres in T-96-11, and 7.02 gm/t / 3.7 metres in T- 96-15).
