I can now answer my own question. For the sake of any others I am posting an answer:
"The term “flow-through share” is a defined term in the Act and is not a distinct type of share under corporate law. In
this case, flow-through shares refers to common shares that will be issued by the Company to investors under a written
agreement with the investors whereby the Company agrees to incur certain eligible resource exploration expenditures,
and to renounce tax losses associated with those expenditures to the investors. If the Company and the investors
comply with the rules of the Act, the investor will be entitled to deduct their proportionate share of the amount
renounced in computing the investor’s income for Canadian income tax purposes and, as a result, the flow-through
shares are issued at a higher price. The tax benefits associated with the Flow-Through Shares are available only to the
initial subscribers thereof (who are Canadian residents) and not to any other person who acquires the Flow-Through
Shares through the on-sale or transfer of those Flow-Through Shares."
