Each Unit is comprised of one common share of Tinka and one half of one common share purchase warrant (each whole warrant, a "Warrant"). Each Warrant will entitle Nexa to purchase one common share of Tinka (each, a "Warrant Share") at a price of C$0.15 per Warrant Share for a period of 18 months following the closing of the Private Placement.

Prior to the Private Placement, Nexa held approximately 18.23% or 71,343,053 of the issued and outstanding common shares of Tinka and did not hold any warrants of Tinka. Upon the closing of the Private Placement, Nexa holds approximately 19.86% or 81,202,208 of the issued and outstanding common shares of Tinka and 4,929,577 Warrants entitling Nexa to acquire 4,929,577 additional common shares of Tinka, representing 56.68% of the issued and outstanding warrants of Tinka.

Nexa has agreed to a restriction on the exercise of any of the Warrants held by it as at the closing of the Private Placement if such exercise would result in Nexa holding in excess of 19.99% of the issued and outstanding common shares of Tinka, unless prior written approval is obtained from the TSX Venture Exchange ("TSXV" or the "Exchange") and Tinka's disinterested shareholders.

All securities issued in connection with the Private Placement are subject to a statutory four-month hold period. The Private Placement was subject to certain conditions customary for transactions of this nature, including, but not limited to, all necessary approvals, including the conditional approval of the Exchange.

The Units were acquired for investment purposes.

Actual results and developments may be substantially different from the expectations described in the forward-looking statements for a number of reasons, many of which are not under our control, among them, the activities of our competition, the future global economic situation, weather conditions, market prices and conditions, exchange rates, and operational and financial risks. The unexpected occurrence of one or more of the abovementioned events may significantly change the results of our operations on which we have based our estimates and forward-looking statements. Our estimates and forward-looking statements may also be influenced by, among others, legal, political, environmental, or other risks that could materially affect the potential development of the project, including risks related to outbreaks of contagious diseases or health crises impacting overall economic activity regionally or globally, as well as risks relating to ongoing or future investigations by local authorities with respect to our business and operations and the conduct of our customers, including the impact to our financial statements regarding the resolution of any such matters.
