Guadalupe de los Reyes

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 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 royalty 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 royalty 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.

Los Cardones

In October 2013, we sold our 100% debt and equity participation in the Los Cardones gold project located in Baja California Sur, Mexico (“Los Cardones Sale”) to Invecture and RPG Structrued Finance S.a.R.L. (the “Purchasers”) for a total of $13,000 ($7,000 of which was paid in October 2013 and $6,000 was originally payable January 2014 (the “Subsequent Payment”) subject to the Purchasers’ option to elect to not make the Subsequent Payment). In 2014, the due date for the Subsequent Payment was extended to January 30, 2015 for additional consideration of $500. In October 2014, Invecture announced that the Los Cardones gold project, had been suspended because the conditions for its development were not favorable at that time, which introduced substantial doubt that the Subsequent Payment would be made. After making this announcement, there were no apparent significant favorable changes to incentivize Invecture to lift the suspension. In January 2015, we agreed to amend the payment terms (the “Amendment”) of the Los Cardones Sale. Under the Amendment, the Company received a payment of $2,994 net of legal costs from the Purchasers as final payment for 100% of the Company’s interest in the project. This resulted in a realized gain of approximately $1,958.

Long Valley

During 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 net smelter return royalty (“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. This sale resulted in a realized gain of $358.

Utah Claims

During 2016 we sold unpatented mining claims located in Utah for $150 and a 2% net smelter return royalty on any future production from said claims. This resulted in a realized gain of $150.
