Option may be exercised by the Optionee by notice delivered to the Optionor, and
upon such notice having been delivered, the Optionor will sell one-half (1/2) of
the Net Smelter  Returns Royalty  (constituting  one percent (1%) of Net Smelter
Returns) to the  Optionee,  for and in  consideration  of the sum of One Million
Dollars ($1,000,000), payable to the Optionor by way of certified cheque or bank
draft within thirty (30) days of the delivery of the notice  exercising  the NSR
Option.
