Cecilia Gold-Silver Project

Cecilia 1 concession encompasses a wide range of rocks from Precambrian granite, to Paleozoic limestone and Cretaceous Cabullona sedimentary group. This succession was strongly affected by major NE and NW structural corridors that created a horst and graben terrain and northwest trending rhyolitic dikes. The six targets, Casa de Piedra, La Mesa, Medias Rojas, Cruz 1, Cruz 2 and Magallanecito are located along these NE and NW regional structures. Soil sampling geochemistry suggests near-boiling zone geochemistry with targets anomalous in gold exceeding 1 g/t (Precipitate Minerals, 2016, unpublished).

• Casa de Piedra and La Mesa target both show the same style of mineralization primarily along NE trending faults extending for at least 2 km across the project area. Alteration and veining are visible within the Cabullona group rocks and increases in the limestone unit noted as jasperoid along structures and near rhyolitic dikes (see Figure 6 below). Some of the best results are located at La Mesa target are: 2.81 g/t Au along a 2 m channel sample; and 0.907 g/t Au and 0.497 g/t Au at Casa de Piedra1. This area is believed to host a deeper target closer to the boundary of limestone and the quartzite.

• Medias Rojas is located along a NE trending structural corridor along which a more or less continuous vein/breccia/stockwork zone can be traced for at least 250 m. The corridor is about 20 m wide and comprises 3 to 5 parallel quartz veins with hematization of rare pyrite, sphalerite and galena. Riverside’s best samples returned 12.5 g/t Au in sandstone and 8.5 g/t Au in rhyolitic dike material. Nineteen of the rock chip samples returned over 0.3 g/t Au. The extent of the mineralization along strike has not been established, but recent work suggests that the vein system extends to the northwest onto the Cecilia 2 concession.

• Cruz I and II are located to the north of the Cecilia 1 concession along and near a major northwest trending corridor that extends for at least 4 km. Geochemistry from soil sampling shows anomalous Te, Au, Pb, Zn and Cu, suggesting that Cruz I and II could be located within the base-metal horizon of an epithermal system. In the field, mineralization is associated with veins and stockwork and alteration zones up to 100 m wide with pervasive, widespread sericitic and silica alteration; sulphides are rare but noted in this area. At Cruz I, ten samples were collected with four samples returning 0.1 to 0.5 g/t Au ¹.
• Magallanecito is an additional rhyolitic dome similar to Cerro Magallanes. Results from sampling highlights a high correlation between gold and silver making this target a priority for additional groundwork.
