Rumiñahui is a 2,910 hectare exploration licence (2 concessions) held 100% by Salazar Resources that hosts copper-gold porphyry targets. The licence is located approximately 100 km northwest of Quito.
The prospect area is cut by the San Francisco river and exhibits a number of historic adits and old workings. Mapping and sampling have indicated the presence of gold-bearing, porphyry-style alteration and veining, shear zones, and quartz-veining.

The Rumiñahui Property was originally explored by informal placer gold miners. While traversing along the San Francisco River the informal miners discovered a large shear zone with narrow quartz veins with high gold grades up to 18 g/t gold and accessory copper and silver. In general this property has under gone very preliminary exploration work that consisted only of limited mapping (on going) and sampling of one old gold prospect (San Francisco Anomaly) and a new quartz sulphide vein (Sune Anomaly), which is about one kilometer south, with interesting gold, copper and silver values.
San Francisco Gold Anomaly
The Curimining geologists collected 109 rock chip channel and composite samples principally along the outcrops that are exposed along the San Francisco River and the Quebrada and other small tributaries. The total area prospected is about 100m X 100m in an area explored by earlier prospectors who did not leave any written record of their work. The assay results have identified three single channel gold anomalies in the bedrock.
- The main anomaly (55m of 2.76 g/t Au) is found along the central part of the area on the east side of the river and includes an area under cut by Tunnel 2 (excavated by previous prospectors). In this area Newmont in 1997 collected a channel sample over 50m that assayed 3.8 g/t gold.
- A smaller anomaly (8m assaying 3.04 g/t Au, 0.11% Cu) is found on the west side of the river in an area under cut by Tunnel 1 (previous prospectors).
- About 50m to the northeast, also on the east bank of the river, is a gold anomaly 10m wide grading 1.33 g/t Au.
