Item 4	Summary of Material Change
	On August 28, 2015, Argentex entered into a letter agreement with Austral Gold Limited (“Austral”) providing for a business combination in which Austral would acquire all of the issued and outstanding Argentex securities not already held by Austral and its affiliates by way of a plan of arrangement or another structure agreed to by the parties.
Item 5	Full Description of Material Change
	5.1 Full Description of Material Change
	On August 28, 2015, Argentex entered into a letter agreement with Austral Gold Limited (“Austral”) providing for a business combination in which Austral would acquire all of the issued and outstanding Argentex securities not already held by Austral and its affiliates by way of a plan of arrangement or another structure agreed to by the parties (the “Transaction”).
	The Transaction is expected to proceed on a friendly basis with the unanimous support and public recommendation of the board of directors of both parties. The letter agreement contemplates that all of the Argentex shareholders other than Austral, Austral Gold Argentina S.A. and Guanaco Mining Company Ltd. (the “Argentex Shareholders”) will receive, in exchange for all of the Argentex shares registered in their name and subject to adjustment pursuant to the Equity Raise Reduction (hereinafter defined), such number of fully paid ordinary shares in the capital of Austral (the “Share Consideration”) equal to 7.75% of the number of ordinary shares of Austral that will be outstanding after the issue of the Share Consideration on the closing date of the Transaction. The Share Consideration shall be issued to the Argentex Shareholders pro-rata according to the number of Argentex shares they own at the record date applicable to the Transaction.

In addition to the Share Consideration, outstanding Argentex share purchase warrants and options issued pursuant to the Argentex stock option plan that are (i) not ‘in-the-money’ and (ii) outstanding on the Closing Date will be amended to provide that the holders will be entitled, upon exercise at any time following the Closing Date, to purchase ordinary shares of Austral at an exercise price equal to the price expressed in their original security adjusted to reflect the exchange ratio of 0.5651 Austral ordinary share to one (1) Argentex common share. The 900,000 options held by three Argentex directors that will be ‘in-the-money’ on the closing date will be cancelled in exchange for cash.

The letter agreement provides that Austral may transfer, assign or distribute to the holders of its ordinary shares, on a pro rata basis, and/or to a trust, the 8,632,000 Argentex warrants held by Austral and Austral Gold Argentina S.A. to enable the transferees to get in exchange warrants to be issued by Austral at closing consistent with the terms and conditions of the warrants (but with the exercise price adjusted as described above), provided that none of them are exercised prior to the closing of the Transaction.

Conditions

Completion of the Transaction is subject to the following terms and conditions:

(a) entering into a definitive agreement or agreements; (b) entering into voting and support agreements with all of the Argentex directors and officers;

(c) satisfactory due diligence by both companies and prior approval of each board of directors; (d) obtaining all applicable regulatory, court, stock exchange and shareholder approvals, on terms and conditions acceptable to both parties; (e) no material adverse change to either party or its assets; (f) the receipt of conditional approval of the listing of Austral Shares on the TSX Venture Exchange and the satisfaction of all listing conditions related thereto, other than those that are administrative in nature and are incapable of being completed prior to the effective time of the Transaction, so that such shares commence trading on the TSX Venture Exchange as soon as practicable after the effective time of the Transaction; (g) lodgment of an application for the listing of all of the shares underlying the Share Consideration on the Australian Securities Exchange (the "ASX"); (h) confirmation by Austral, on or before September 30, 2015, that Argentex management will not be entitled to receive any payment or benefit due solely to the completion of the Transaction, other than “catch-up” payments intended to reimburse them for a temporary salary/fee reduction that took effect on May 1, 2015. Austral shall be permitted to conduct meetings and engage in discussions with the Argentex executive officers with a view to agreeing on or before September 30, 2015, that post-closing, each such executive will not exercise any rights to terminate their employment agreement for “good reason”, including as the result of any change in his current duties, position, authority or responsibilities, provided there is no reduction of their salary/fees; and (i) confirmation by Austral, during due diligence, that Argentex will not, at the effective time of the Transaction, be liable for salary, severance and employment related taxes for employees in Argentina in excess of U.S.$20,000 in the aggregate, and that all of those employees will be duly registered.

(j) Confirmation by Austral that Argentex and its subsidiary or branch in Argentina will not, at the effective time of the Transaction, be liable for any fees payable to any financial advisor of Argentex other than those reasonable and customary fees related to the issuance of the fairness opinion in connection with this Transaction.

Exclusive Negotiation

From the date the offer letter is signed until October 31, 2015 (the "Exclusivity Period"), the parties have agreed to negotiate exclusively and in good faith with one another with a view to settling the definitive agreement as soon as possible.

During the Exclusivity Period, both parties have agreed not to issue any debt, equity or equity-like securities other than in connection with previously granted options or warrants or as otherwise expressly agreed in writing. Notwithstanding the foregoing, Austral will have the right to raise up to AUD$10MM through the sale of its equity securities at a price of AUD$0.15 or more per Austral Share in order to fund the construction of its Amancaya plant or the development of an agitation plant at its Guanaco property without Argentex consent. If Austral completes a financing by issuing equity securities at a price that is AUD$0.15 or more per Austral Share, then the Share Consideration Percentage will be reduced proportionately to reflect such issuance (the "Equity Raise Reduction"). Austral also has the right to either (i) grant any right, title, or interest in or to encumber assets or shares of Austral, Austral Gold Argentina S.A., Guanaco Compañía Minera Limitada or Guanaco Mining Company Limited or of newly acquired assets or shares, and/or (ii) issue any debt or borrow money in order to fund certain initiatives, provided that in such case the Argentex board will be informed prior to the execution of any binding agreement and/or may participate in the analysis or discussions of the relevant transaction and provided, further, that the issuance of debt or shares and/or the encumbering of assets or shares in connection with the acquisition of new projects will be subject to the approval of the Argentex board.

TSX-V Listing

Austral has agreed to apply and use its best efforts to cause the ordinary shares of Austral to become listed for trading on the TSX Venture Exchange, with the intention that such shares will commence trading on the TSX Venture Exchange as soon as practicable after the effective time of the Transaction.

Expenses and Termination Fees

Each party will be responsible for its own respective fees, costs and expenses incurred in the Transaction. If the parties sign a definitive agreement during the Exclusivity Period, Austral has agreed that it will lend money to Argentex to be used to satisfy the latter’s transaction expenses in accordance with an agreed budget. If the Transaction does not close after the parties have executed a definitive agreement, the letter agreement contemplates that one or the other of the parties may be required to pay a termination fee, depending on the reasons why the transaction did not close.

Argentex Signs Binding Offer Letter to be Acquired by Austral Gold

Vancouver, BC, Canada – August 31, 2015 - Argentex Mining Corporation ("Argentex" or the "Company") (TSX-V: ATX, OTCQB: AGXMF) is pleased to announce that it has signed a binding offer letter from Austral Gold Limited (“Austral Gold”) (ASX: AGD) in connection with the acquisition of 100% of the issued and outstanding equity of Argentex in a share exchange transaction to be conducted by way of a plan of arrangement pursuant to the provisions of the Business Corporations Act (British Columbia) (the “Transaction”).

About the Transaction

The binding offer letter contemplates that Argentex shareholders (other than Austral Gold and two of its affiliates, which already own an aggregate of 19.9% of the outstanding Argentex common shares), will receive Austral Gold shares representing approximately 7.75% of the total outstanding shares of Austral Gold after adjusting for the shares issued in the Transaction. This percentage is subject to adjustment in limited circumstances. Austral has agreed to apply for a listing on the TSX Venture Exchange, with the intention that such shares will commence trading on the TSX Venture Exchange as soon as practicable after the effective time of the Transaction. Austral Gold is currently listed on the Australian Stock Exchange and plans to maintain this listing.

The proposed Transaction contemplates each Argentex share being exchanged for 0.5651 Austral shares. This implies a price of approximately $CAD0.08 for each Argentex share based on the AGD 20 day VWAP of $AUD0.154 at market close 28 August, and the average weekly Bank of Canada $CDN/$AUD exchange rate of 0.9458 for the week ending the 28 August.

This represents a 230% premium over TSX-V closing price on 28 August and a 231% premium over the 20 day VWAP of Argentex for the 20 trading day period ended 28 August. Adjusting the premiums for AGD and affiliates ownership results in 184% and 185% premiums respectively.

Completion of the transaction is subject to a number of key terms and conditions including:

Entering into a definitive agreement by October 31, 2015;

Satisfactory due diligence and Board approvals;

Regulatory, stock exchange and shareholder approvals;

Satisfaction of all listing conditions and conditional approval from TSX Venture Exchange to enable an AGD listing on the TSXV as soon as practical after transaction close.

Argentex and Austral Gold have agreed to negotiate exclusively until October 31, 2015 and the binding offer letter contains customary restrictions on the parties’ abilities to conduct certain types of transactions with third parties until closing. In addition, the binding offer letter contemplates that, upon execution of the definitive agreement, Austral Gold will provide bridge financing to Argentex to enable Argentex to pay Transaction costs and it will retain Argentex to provide certain consulting services on a monthly fee basis until the Transaction is completed. If the Transaction is not completed, the binding offer letter contemplates that the definitive agreement will provide for the payment of a termination fee by one or the other party, but only in limited circumstances, and Argentex may be required to repay the bridge loan. This news release provides only a summary of the terms of the binding offer letter – a copy of the binding offer letter will be filed on SEDAR.

“We are excited by the prospect of merging with Austral Gold to create a platform of growth for precious metals in South America. The merger will create a Company with a unique blend of operations and development projects in the Americas, with access to existing cash flow from a low cost Guanaco mine in Chile. The Company will have a highly experienced development and operational team which will advance our Pingüino project with the ability to exploit other opportunities in the region. This presents a unique value proposition for our shareholders in the current market,” stated Mike Brown, President and CEO of Argentex. “We believe that the Transaction adds immediate value for our existing shareholders while providing Austral Gold with additional quality development projects, an experienced exploration team and corporate and market experience, which is reflected in the attractive premiums of the offer” concluded Mike Brown.

Mr. Eduardo Elsztain, Chairman of Austral Gold commented: "The proposed acquisition of Argentex represents another step in our objective of becoming a broad-based precious metals company and a leading regional player in South America. We have had a strategy of patiently and prudently deploying our capital to invest in projects and equity stakes in precious metals companies that we believe have considerable upside value. Argentex represents one such opportunity and we are confident that its shareholders will recognise the benefits of being part of Austral Gold. As well, we believe now is the right time to pursue a listing on the TSX Venture Exchange as this will give us access to a wider investor base in North America where our group of companies has a well-established and strong reputation. This investor base will be important as we continue to strengthen our asset base in South America. We have a number of additional opportunities we are pursuing and we look forward to updating shareholders in this regard.”

Benefits to Argentex Shareholders

The potential transaction, apart from providing a significant premium to Argentex’s recent share price, offers upside potential:

i. Cash flow from small low cost underground gold mine in Chile; ii. Potential for regional consolidation in Chile and Argentina; iii. Experienced development and operational teams ‘on-the-ground’ in Argentina and Chile; iv. Highly successful and well connected Argentinean majority owner.
