American CuMo Mining provides update on Strategic Financial Partnership with Millennia Minerals

The MOU outlined the broad terms of a US$200 million private placement from Millennia to fund early-stage exploration through to pre-feasibility on the Calida Gold project owned by Poly Resources LLC for US$100 million and to provide funding to continue the development of the Company's CuMo Project through to feasibility for US$100 million. The MOU was subject to Millennia's completion of legal, technical, and financial due diligence.

During the process of completing its due diligence, Millennia determined that additional financial structuring was required in connection with its investment. This led to the parties engaging in further negotiations that changed the timing and structure of the investment.

As a result of these negotiations, the parties have agreed in principal that:

• Millennia would have the right to acquire up to a 70% equity interest in Poly Resources for US$100 million, which amount would be invested in accordance with the following schedule: (i) US$5 million for a 25% membership interest in Poly Resources on or about June 20, 2017, of which US$1million has already been paid by Millennia, as announced by CuMoCo on March 15, 2017, (ii) US$5 million for an additional 25% membership interest in Poly Resources on or about the later of June 30, 2017 or the date Poly Resources receives all of the required permits for its planned 2017 exploration drilling program, (iii) US$40 million for an additional 10% membership interest in Poly Resources not later than 30 days following receipt of a National Instrument 43-101 compliant resource report on the Calida Project (the "Third Contribution"), and (iv) US$50 million for an additional 10% membership interest in Poly Resources not later than the first anniversary of the Third Contribution;

• Millennia would have the right to acquire up to a 20% equity interest in Idaho CuMo for US$100 million, which amount would be invested in accordance with the following schedule: (i) US$10 million for a 2% equity interest in Idaho CuMo not later than June 30, 2017, (ii) US$15 million for an additional 3% equity interest in Idaho CuMo not later than December 31, 2017, (iii) US$25 million for an additional 5% equity interest in Idaho CuMo not later than June 30, 2018, (iv) US$25 million for an additional 5% equity interest in Idaho CuMo not later than December 31, 2018 and (v) US$25 million for an additional 5% equity interest in Idaho CuMo not later than June 30, 2019;

• Millennia is to subscribe for eleven million common shares of the Company for an aggregate subscription price of US$3 million, which subscription is to occur concurrently with its US$10 million instalment to be paid to Idaho CuMo Mining Corporation. This subscription for CuMoCo common shares increases Millennia's aggregate investment to a total of US$203 million in staged funding into CuMoCo and CuMoCo's two projects;

• Concurrent with each investment by Millennia in Poly Resources or Idaho CuMo, Millennia would receive the right to receive warrants, issuable upon the consummation of a take-over transaction of CuMoCo by an independent third-party, to purchase such number of common shares of CuMoCo as equals the amount of such investment divided by the share price of CuMoCo common shares at the time of such investment (and with an exercise price equal to such share price);

• Upon execution of definitive agreements in respect of the transactions contemplated, Millennia would receive the right to receive warrants, issuable upon a determination that the Calida Project was non-viable, to purchase either (i) common shares of CuMoCo, the value of which would be equivalent to the amount of the initial contribution to Poly Resources of US$5 million actually expended at the time of exercise of such warrants, or (ii) Idaho CuMo secured silver stream notes, the value of which would be equivalent to the amount of the initial contribution to Poly Resources of US$5 million actually expended at the time of exercise of such warrants, or alternatively, Millennia would have the right to earn an additional 20% interest in Idaho CuMo by investing another US$100 million;

• Millennia would receive the right to receive warrants, issuable upon Millennia's investment of US$10 million in each of Poly Resources and Idaho CuMo, to purchase one percent (1%) of CuMoCo's common shares at an exercise price equal to the trading price of CuMoCo common shares as of the close of trading on the day after CuMoCo's announcement of Millennia's US$10 million investment in each of Poly Resources and Idaho CuMo; and

• Millennia would have the right to terminate the definitive agreement governing the foregoing transactions at any time and, not later than the first anniversary of such termination, CuMoCo would be required to purchase within that 365 day period all of the equity interests in Poly Resources and Idaho CuMo for a purchase price equal to the cost thereof plus, if at the time of such termination Millennia had made total investments of at least US$5 million, 20% of the amount of such investments that had been expended by Poly Resources or Idaho CuMo.

Millennia has advised CuMoCo they are satisfied that the risk and control measures included in the legal agreements for the Calida Gold project development are suitable for an early stage exploration project. Millennia has also informed CuMoCo they are still undertaking technical and financial due diligence on the CuMo Project and that they expect to complete the initial investment funding on time as described above, subject to completion of final legal due diligence and regulatory approval.

This financing transaction is subject to receipt of TSX Venture Exchange approval.
