("Tinka") (TSXV: TK) (BVL: TK) (OTCQB: TKRFF), as part of a larger non-brokered private placement financing of units of Tinka, the first tranche of which closed today (the "Private Placement").

Under the terms of the Agreement, Nexa acquired 9,859,155 units of Tinka (the "Units") at a price of C$0.10 per Unit, for aggregate proceeds of C$985,915.50 (or US$700,000), having exercised its rights under the pre-existing investor rights agreement with Tinka (the "Investor Rights Agreement"). 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. Nexa intends to review, on a continuous basis, various factors related to its investment in Tinka and may decide to acquire or dispose of additional securities of Tinka through the market, privately or otherwise, as future circumstances may dictate (including under its pre-emptive rights), subject in all cases to market conditions and compliance with applicable securities laws. Under the terms of the Investor Rights Agreement, Nexa has, among others, a pre-emptive right to maintain its percentage interest in the outstanding common shares of Tinka, in connection with any future issuances of Tinka securities, subject to certain exclusions.

Forward-looking statements are not guarantees and involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. 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.
