2. Year 2 - US$250,000.
   
3. Year 3-7 - Minimum of US$200,000 per annum.

The Rio Negro Project comprises three (3) contiguous concession contracts together with three (3) pending concession applications covering approximately 2,245 hectares. Regional mapping indicates that the property covers roughly 16 kilometers of highly prospective ground along the Bucaramunga Fault Zone at and near the interpreted intersection with structures related to the California Belt. The deep seated Bucaramunga Fault Zone is believed to be the primary control for focusing gold bearing magmas and fluids that developed the California and Vetas Districts that are estimated to host more than 16 million ounces of past production plus known resources. Reconnaissance sampling and mapping has returned values to 23 grams gold per metric tonne (g/T Au from vein structures), and also identified porphyry style Quartz - Sericite - Pyrite (QSP) alteration on the property that has yielded values to 3 g/T Au.

Importantly, this Agreement is consistent with the prospect generation portion of the Company's business model, assuring substantial work will be done on the property, maintaining significant upside exposure to discovery and future production potential for the Company's shareholders, with a free ride and no additional costs through to production.
