("Calvista Colombia") has entered into three option agreements with certain individuals in the Republic of Colombia to acquire certain interests in mining exploration licenses located in the California District in the Department of Santander, Colombia as follows (i) up to a 100% interest in license 90-68 (El Carmen), comprising 10 hectares and 81 square meters, in two stages, one for 20% of the license and another for 80% of the license, and (ii) a 16.66% interest in license 39-68 (Los Andes), comprising 31 hectares and 1145 square meters, (see Figure 1). The option agreements are subject to TSX approval. The holders of the mining licenses are in the process of transferring to Calvista Colombia their applicable interests in the mining licenses. These interests are subject to transfer back by Calvista Colombia in the event Calvista Colombia does not exercise the options.

License 90-98 (El Carmen): Calvista Colombia has an option to acquire up to a 100% interest in mining license 90-68 (El Carmen) by way of two option agreements, one for a 20% interest in the El Carmen property (the "20% Interest") and one for an 80% interest in the El Carmen property (the "80% Interest"). The 20% Interest will be exercisable as follows: (i) paying upon execution of the option agreement, US$150,000, (ii) paying upon registration at the Colombian mining authority of the transfer of the 20% Interest to Calvista Colombia, an additional US$150,000 plus an aggregate of fifty thousand common shares of Calvista, and (iii) paying, upon the exercise of the option, an additional amount of US$210,000 plus four hundred and forty thousand common shares of Calvista, and granting a 1.5% net smelter return royalty on gold and silver on 20% of the production from the El Carmen property. The 80% Interest will be exercisable as follows: (i) paying upon execution of the option agreement, US$150,000, (ii) paying upon registration at the Colombian mining authority of the transfer of the 80% Interest to Calvista Colombia, an additional US$150,000 plus an aggregate of four hundred thousand common shares of Calvista, and (iii) paying upon the exercise of the option, an additional amount of US$300,000 plus four hundred thousand common shares of Calvista, and granting a 1.5% net smelter return royalty on gold and silver on the remaining 80% of production from the El Carmen property. If after the exercise of the option on the 80% Interest the aggregate amount of cash paid and common shares of Calvista issued for such exercise is less than US$2,000,000, Calvista Colombia will pay the difference in either cash or common shares of Calvista, at the option of Calvista Colombia. The issuance of common shares of Calvista in accordance with the option agreements is subject to approval by the TSX. In accordance with the execution of option agreements, the holder of the mining license has submitted to the mining authorities all documents required to effect the transfer of the 20% Interest and the 80% Interest to Calvista Colombia, and the term of the option agreements will run for 18-months from the date of the registration of such transfers by the mining authority. In the event Calvista Colombia elects not to exercise the options, Calvista Colombia will transfer back its interests in the mining license.

Upon exercise of the options, Calvista Colombia will have acquired a 100% interest in license 90-68 (El Carmen), providing Calvista substantial control over a strike length of approximately 600 metres along the mineralized corridor southwest from Angostura and through Mascota, as stated in the Technical Report of the California Project NI 43-101. License 90-68 (El Carmen) is adjacent to the Callejon Blanco property (license 37-68) where drill results returned ranged from below detection to 1.53 m @ 71.2 g/t Au, and included the following select results:

Potential quantity and grade is conceptual in nature. There has been insufficient exploration to date to define a mineral resource on 37-68, and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

License 39-68 (Los Andes): Pursuant to the option agreement, Calvista Colombia has an option to acquire a 16.66% interest (the "16.66% Interest") in mining license 39-68 (Los Andes) by (i) paying upon execution of the option agreement, US$175,000, (ii) paying, upon registration at the Colombian mining authority of the transfer of the 16.66% Interest to Calvista Colombia, an additional US$175,000 plus an aggregate of three hundred thousand common shares of Calvista, and (iii) paying, upon the exercise of the option, an additional amount of US$350,000 plus three hundred thousand common shares of the Company, and granting a 1.5% net smelter return royalty on gold and silver on 16.66% of production from the properties. In accordance with the option agreement, the holder of the mining license has 5 business days from the initial payment to submit to the mining authorities all documents required to effect the transfer of the 16.66% Interest to Calvista Colombia, with the term of the option agreement running for 18-months from the date of such registration. In the event Calvista Colombia elects not to exercise the option, Calvista Colombia will transfer back the 16.66% Interest. The issuance of shares of the Company in accordance with the option agreement is subject to approval by the TSX. License 30-68 (Los Andes) is located on the south west extension to the mineralization drilled last year by Calvista on the Buenavista property (license 14031) where drill results returned ranged from below detection to 1.53 m @ 67.65 g/t Au, and included the following select results:
