OVERVIEW
La Silla Project, 100% owned by Riverside Resources, is located in the prolific Gold-Silver belt recording multiple current productions to the north and recent high-grade precious metals discoveries to the south of the project.
La Silla is an epithermal gold-silver system with similarities to the San Dimas (M+I: 70.7Moz Ag and 0.8Moz Au1; First Majestic) and El Gallo vein systems (297,000 AuEq2; McEwen Mining), all located to the north. The project is 2,070 hectares in size and includes the two primary large vein targets: El Roble and Ciruelos (see Figure 1). The El Roble target is located on a north-south structure while the Ciruelos vein is located on a northwestern structure.
At local scale, fieldwork by Riverside highlighted extension of the vein on Riverside’s claim for at least 400 m in strike length and up to 365 ft in depth, which was defined by historical drilling in 2004 by Meridian Gold Company. It includes multiple intersections of multi-stage white to green quartz with abundant iron oxides replacing sulphides, for which results returned 15.24 m at 6.59 g/t Au and 33.4 g/t Ag in hole ER001 at the El Roble target (Meridian Gold Company, April 16, 2004).
At surface, Riverside’s work defined multiple high grade zones as well as several parallel veins suggesting district scale potential. Some of the best results are listed below in table 1.

| RRI-2399 | 19.9 | 200.0 | 1.0 |
| RRI50315 | 9.4 | 196.0 | 1.0 |
| RRI-2351 | 2.4 | 113.0 | 1.5 |

| RRI-2366 | 1.0 | 14.0 | 2.0 |
| RRI-2369 | 1.6 | 40.1 | 2.0 |
| RRI-2389 | 1.8 | 2.7 | 1.0 |
As part of the Ollitas Mining District, La Silla project is located within the San Ignacio Municipality. The project can be easily access from Mazatlan via highway to San Ignacio and then on dirt roads from the town San Ignacio.
