Exploration carried out over the past year by International Tower Hill Mines (VSE) on its Siwash property in southwestern British Columbia has focused on two areas.
A program of geophysics and overburden drilling has attempted to define the NE Grid and the Chicago zone areas. An induced-polarization survey determined that a chargeability anomaly corresponds to a copper-zinc soil anomaly measuring 600 by 1,100 metres in the NE Grid. Areas of a
chalcopyrite-hematite-mineralized intrusive lie within the zone. The company believes the target offers potential for porphyry-style copper mineralization. The Chicago zone is a quartz sulphide shear, 2.5 to 3.5 metres in width, which trends in an east-west direction. Overburden drilling returned anomalous values for gold, silver and copper, in addition to values as high as 3.32% lead and 4.11% zinc over 5-ft. intervals.
Additional geophysical work will be followed by diamond drilling.
