DIAZ ANNOUNCES Q1 2013 FINANCIAL RESULTS Diaz Resources Ltd. (TSXV: "DZR") ("Diaz" or the "Company") announces that it has filed its interim Financial Statements and MD&A for the three months ended March 31, 2013 on SEDAR.

During the quarter, Diaz's production increased to 382 BOEd from 302 BOEd in Q4 2012 due to the Company's shut-in shallow natural gas wells being placed back on production. The Company did not participate in drilling any new wells during the quarter due to a lack of working capital to finance new development and the operator of the Macklin field did not propose any new wells as a result of lower heavy oil prices.
It is anticipated that further heavy oil development drilling at Macklin will be planned for the third quarter of 2013. A thorough review of the Company's ability to raise additional capital or other financing methods to participate in this drilling resulted in few viable choices. Negative issues included: poor capital markets for junior energy companies in Canada, no ability to increase debt capacity, a poor environment for selling producing properties on acceptable terms, and a negative market in which to make farm-out deals on favorable terms. As a result of the foregoing, Management believes that the proposed merger with Tuscany Energy Ltd. described below is the most favorable route to preserve Diaz's shareholders' equity and allow the Diaz shareholder's to benefit from ownership in a larger, more active entity.

Proposed Merger With Tuscany Energy Ltd.

On May 17, 2013, Tuscany Energy Ltd. ("Tuscany") and Diaz announced that they had entered into an agreement whereby, subject to certain conditions including obtaining shareholder, court and all necessary regulatory approvals, Tuscany will acquire all of the common shares of Diaz (the "Transaction"). After the acquisition of Diaz, Tuscany plans to reorganize its capital structure by the consolidation of its shares on the basis of
1 new share for every 8 shares outstanding.
It is anticipated that Tuscany will issue 0.31 common shares for each outstanding Diaz common share. Following the Diaz acquisition it is expected that Tuscany, on a proforma basis, will have:
