During October 2017, we entered into an agreement (the “Option Agreement”) to option our interest in the Guadalupe de los Reyes gold and silver project in Sinaloa, Mexico (the “GdlR Project”) to Minera Alamos Inc. and its subsidiary Minera Alamos de Sonora S.A. de C.V. (“Minera Alamos”).

Pursuant to the terms of the Option Agreement, we granted Minera Alamos an exclusive right and option right to earn a 100% interest in the GdlR Project by:

making payments totaling $6,000 comprised of a payment of $1,500 made at the execution of the Option Agreement (“Option Grant Date”); two successive payments of $1,500 each to be made at the one-year and two-year anniversaries of the Option Grant Date; and a final $1,500 payment to be made before the four-year anniversary of the Option Grant Date;

maintaining the concessions comprising the GdlR Project in good standing;

fulfilling all of our obligations to the Ejido La Tasajera (the “Ejido”) as set out in the temporary occupation contract between us and the Ejido;

granting us a capped NSR on production from open pit mining (the “Open Pit NSR”) at rates that range from 1% (at gold prices of $1,400/oz or less) to a maximum of 2% (at gold prices above $1,600/oz) up to an aggregate of $2,000 in royalty payments;

granting us a perpetual NSR on production from underground mining (the “Underground NSR”) at rates that range from 1% (at gold prices of $1,400/oz or less) to a maximum of 2% (at gold prices above $1,600/oz); and

granting us the right to assume a 49% non-carried interest in an underground project if Minera Alamos decides to develop an underground mine at the GdlR Project (the “Back-in Right”).

The Option Agreement provides that all cash payments are non-refundable and optional to Minera Alamos, and in the event Minera Alamos fails to pay any of the required amounts as set out in the Option Agreement, or fails to comply with its other obligations, the Option Agreement will terminate and Minera Alamos will have no interest in the GdlR Project. Provided it is not in breach of the Option Agreement, Minera Alamos may at its discretion advance the above payment schedule.

Subject to Minera Alamos timely making all the option payments, and fulfilling its other obligations with respect to the Option Agreement, we will transfer 100% of the shares of the Company’s 100% owned subsidiary Minera Gold Stake S.A. de C.V., the entity which owns the GdlR Project, to Minera Alamos and the Open-Pit NSR and Underground NSR will be granted to us.

If Minera Alamos discovers, and decides to develop, an underground mine at the GdlR Project and we exercise the Back-in Right, we and Minera Alamos have agreed to form a joint venture to develop and operate the underground mine. If the joint venture is formed, the Underground NSR will terminate.

The Company has determined that control of the GdlR Project has not been transferred for accounting purposes. The first option payment of $1,500 received in October 2017 has been accounted for as reduction to carrying value. Subsequent option payments received, if any, will be accounted for as further reductions to carrying value. After the carrying value has been reduced to zero, remaining option payment proceeds, if any, will be recognized as a contract liability until control of the GdlR Project has transferred to the buyer or the Option Agreement has been terminated. In addition, in accordance with our policy, potential royalty revenue and future option payments have been fully constrained.

Long Valley Claims

During the three months ended March 31, 2017, we sold our Long Valley unpatented mining claims located in California for consideration, net of transaction costs, of $358 which was paid at closing; a future payment of $500 one month after the start of commercial production; a future payment of $500 on or prior to the first anniversary of the start of commercial production; and a NSR on any future production from said claims at a variable rate between 0.5% and 2.0% depending on the average gold price realized. The Company has determined that control of the Long Valley claims were transferred to the buyer at the time of sale for accounting purposes. This sale resulted in a realized gain of $358.
