    (b) Issued:

     

    (i) In February 2017, the Company received regulatory approval for a normal course issuer bid to acquire up to 10.9 million common shares of the Company representing approximately up to 5% of its issued and outstanding common shares at that time. The bid was effective on February 8, 2017 and terminated on February 7, 2018, or on such earlier date as the bid was completed. The actual number of common shares purchased under the bid and the timing of any such purchases was at the Company’s discretion. Purchases under the bid shall not exceed 86,128 common shares per day. The Company shall pay the prevailing market price at the time of purchase for all common shares purchased under the bid, and all common shares purchased by the Company will be cancelled. For the year ended December 31, 2017, the Company purchased 2.6 million shares for CAD$213,700 with an average price of CAD$0.08 per share, of which 2.5 million common shares have been cancelled and the remaining common shares were cancelled in February 2018. Subsequent to December 31, 2017, a further 86,000 common shares for CAD$6,450 were purchased at an average price of CAD$0.08 per share, all of which were cancelled in February 2018.

     

    In March 2017, stock options for 500,000 common shares were cancelled for the exercise of share appreciation rights for 272,727 common shares at a fair value of CAD$0.10 per share. In May 2017, stock options for 132,500 common shares were cancelled for the exercise of share appreciation rights for 29,166 common shares at a fair value of CAD$0.10 per share.

     

    On April 21, 2017, the Company closed a private placement for 3.8 million flow through common shares at CAD$0.13 per share for gross proceeds of CAD$500,000. The fair value of the shares was CAD$0.11 per share, resulting in the recognition of a flow through premium liability of CAD$0.02 per share for a total of CAD$76,900. Finder fees were comprised of CAD$32,500 in cash and 250,000 warrants; each warrant is exercisable to acquire one non-flow through common share at an exercise price of CAD$0.15 per share until April 21, 2019.

     

    (ii) In March 2016, the Company closed a private placement in two tranches totalling 22.7 million units at a price of CAD$0.09 per unit for gross proceeds of CAD$2.04 million with each unit comprised of one common share and one-half of one common share purchase warrant; each whole warrant is exercisable to acquire one common share at an exercise price of CAD$0.12 per share for a period of three years. On March 3, 2016, the Company closed the first tranche for 17.7 million units for gross proceeds of CAD$1.59 million. On March 14, 2016, the Company closed the second tranche for 5 million units for gross proceeds of CAD$449,500 with a finder’s fee of 311,111 units issued with the same terms as the underlying units in the private placement.

     

    In September 2016, the Company issued 250,000 common shares at a value of CAD$0.10 per share to Eureka for the FG gold property (Note 9(a)(iii)).

     

    In 2016, warrants for 1.31 million shares were exercised for proceeds of CAD$104,700 which included finder fee warrants for 58,333 shares with a fair value of US$2,000. In 2016, stock options for 1 million shares were exercised for proceeds of CAD$80,000 with fair values of US$54,300.

     

    (iii) On September 21, 2015, the Company closed the first tranche of a private placement for 11.5 million units at a price of CAD$0.06 per unit for gross proceeds of CAD$690,000. Each unit was comprised of one common share and one-half of one common share purchase warrant; each whole warrant is exercisable to acquire one common share at an exercise price of CAD$0.08 per share until September 21, 2018. The Company paid CAD$36,200 in cash and issued 594,844 in warrants as finders’ fees. The finders’ fee warrants have the same terms as the underlying warrants in the unit private placement. On October 30, 2015, the Company closed the second tranche of a private placement for 1.67 million units at a price of CAD$0.06 per unit for gross proceeds of CAD$100,000 with Marlin Gold (Note 7(a)(i)). Each unit was comprised of one common share and one-half of one common share purchase warrant; each whole warrant is exercisable to acquire one common share at an exercise price of CAD$0.08 per share until October 30, 2018.

     

    On September 24, 2015, the Company issued 2 million shares at a value of CAD$0.07 in settlement of partial salaries owed to certain officers and fees owed to certain directors in which the latter also forgave a certain portion of outstanding directors fees owed, resulting in a gain on debt settlement of $54,000.

     

    On October 8, 2015, the Company entered into the Share Purchase Agreement with Marlin Gold which closed on October 30, 2015 whereby the Company issued 19 million common shares at a value of CAD$0.07 per share to Marlin Gold to acquire a 100% interest in Marlin Gold’s wholly-owned subsidiary, Oro Silver, which owns the El Compas project through its wholly-owned Mexican subsidiary, Minera Oro Silver (Note 7(a)(i)).

     

    (c) Stock option plan:

     

    The Company has a stock option plan that allows it to grant stock options to its directors, officers, employees, and consultants to acquire up to 44,261,695 common shares which was increased from 18,888,434 common shares at the Company’s Annual and Special Meeting held on June 2, 2017. The exercise price of each stock option cannot be lower than the last recorded sale of a board lot on the TSX during the trading day immediately preceding the date of granting or, if there was no such date, the high/low average price for the common shares on the TSX based on the last five trading days before the date of the grant. Stock options have a maximum term of ten years and terminate 30 days following the termination of the optionee’s employment, except in the case of death, in which case they terminate one year after the event. Vesting of stock options is made at the discretion of the board at the time the stock options are granted.

     

    At the discretion of the board, certain stock option grants provide the holder the right to receive the number of common shares, valued at the quoted market price at the time of exercise of the stock options, that represent the share appreciation since granting the stock options.

     

    The continuity of outstanding stock options for the years ended December 31, 2017, 2016 and 2015 is as follows:

    During the year ended December 31, 2017, the Company recognized share-based payments of $366,000 (2016 - $301,000 and 2015 - $161,000), net of forfeitures, based on the fair value of stock options that were earned by the provision of services during the period. Share-based payments are segregated between directors and officers, employees and consultants, as applicable, as follows:

     

        December 31,  
        2017     2016     2015  
                       
    Directors and officers   $ 351     $ 245     $ 153  
    Employees     15       2       8  
    Consultants     -       54       -  
        $ 366     $ 301     $ 161  

     

    The weighted average fair value of stock options granted and the weighted average assumptions used to calculate share-based payments for stock option grants are estimated using the Black-Scholes option pricing model as follows:

      

        2017     2016     2015  
                       
    Number of stock options granted     3,600,000       8,010,000       5,950,000  
    Fair value of stock options granted (CAD$)   $ 0.08     $ 0.07     $ 0.05  
                             
    Market price of shares on grant date (CAD$)   $ 0.10     $ 0.09     $ 0.06  
    Pre-vest forfeiture rate     15.41 %     15.99 %     19.64 %
    Risk-free interest rate     0.95 %     0.55 %     0.75 %
    Expected dividend yield     0 %     0 %     0 %
    Expected stock price volatility     134 %     140 %     140 %
    Expected option life in years     4.03       4.42       4.24  

     

    Expected stock price volatility is based on the historical price volatility of the Company’s common shares.

     

    In May 2015, certain directors and officers of the Company cancelled 3,360,000 stock options with exercise prices ranging from CAD$0.10 to CAD$0.145 and expiry dates ranging from September 2015 to June 2017.

    (g) Shareholder rights plan:

      

    On May 31, 2005, the shareholders of the Company approved a shareholder rights plan (the “Plan”) that became effective on April 30, 2005. The Plan was intended to ensure that any entity seeking to acquire control of the Company makes an offer that represents fair value to all shareholders and provided the board of directors with sufficient time to assess and evaluate the offer, to permit competing bids to emerge, and, as appropriate, to explore and develop alternatives to maximize value for shareholders. Under the Plan, each shareholder at the time of the Plan’s adoption was issued one Right for each common share of the Company held. Each Right entitled the registered holder thereof, except for certain “Acquiring Persons” (as defined in the Plan), to purchase from treasury one common share at a 50% discount to the prevailing market price, subject to certain adjustments intended to prevent dilution. The Rights were exercisable after the occurrence of specified events set out in the Plan generally related to when a person, together with affiliated or associated persons, acquires, or makes a take-over bid to acquire, beneficial ownership of 20% or more of the outstanding common shares of the Company. The Rights expired on April 30, 2015.
