(g) Share-based payments
The Company grants stock options to directors, officers, employees and consultants of the Company. The fair value of share-based payments to employees is measured at grant date, using the Black-Scholes option pricing model, and is recognized over the vesting period using the graded method. Fair value of share-based payments for non-employees is recognized and measured at the date the goods or services are received based on the fair value of the goods or services received. If it is determined that the fair value of goods and services received cannot be reliably measured, the share-based payment is measured at the fair value of the equity instruments issued using the Black-Scholes option pricing model.
For both employees and non-employees, the fair value of share-based payments is recognized as either an expense or as mineral property interests with a corresponding increase in option reserves. The amount to be recognized as expense is adjusted to reflect the number of share options expected to vest. Consideration received on the exercise of stock options is recorded in capital stock and the related share-based payment is transferred from the stock option reserve to capital stock. For unexercised options that expire, the recorded value is transferred to deficit.
