Directors buying over $1 million of shares!Strong insider buying by 2 Nanoxplore directors this week at prices above the current share price ($4.34 per share). Cameron Harris and Denis Labreque exercised options at a strike price of $4.34 to purchase over 260,000 shares (combined). They wrote personal cheques for over $1 million. Clearly putting their money in an investment that they have a high conviction!
