The 251 km2 Tajitos Gold Project in Sonora, Mexico was acquired by combining the Company's Mexico Database, local geologic knowledge, historic production data, and extensive personal networks. There have been at least 3 operational campaigns over the past 100 years on the property of high grade gold from veins. Recent drilling by Penmont Mining Company intersected gold quartz veins and found mineralization extending beyond the veins into the wall rock zones on ground now optioned by Riverside from a private claim owner. Penmont's RC drilling did not give any core and thus further structural interpretations will be completed by Riverside as the Company progresses this newly acquired district
The results from rock chip geochemical sampling by the Mexican Geological Survey (MGS) on the vein systems identified on the Tajitos -- Tejo property range from 1.5 g/t to 22.8 g/t gold and from 28 g/t to 44 g/t silver over widths ranging from 0.5 to 3.0 metres. Initial limited rock chip geochemical sampling on the property by Riverside has so far yielded results ranging from 0.05 g/t gold to 38.7 g/t gold and 383 g/t silver over widths of 1.5 metres in 220 samples. These results are comparable to the results found by the MGS and support the concept of structurally controlled precious metal mineralization. This high gold: silver ratio is typical for orogenic gold (shear zone gold) anomalies like the >7 million ounce Herradura mine that is located 70 km away along the same NW strike, locally known as the "Mojave-Sonora Megashear". This trend is the most prolific gold producing belt in Mexico and Tajitos is located in the heart of it.
The Tajitos Gold Project consists of the 207 hectare Tajitos property to the west and the 5,781-hectare Tejo Concession to the south and east. On the Tajitos property proper, two vein systems were mined during the 1800 and 1900's and since that time a larger potentially open pit gold target has been identified. Historically mines on the property only extracted the high grade quartz veins and did not focus on the broad oxidized, disseminated gold potential. This style of disseminated gold mineralization on the Tajitos Project can be compared to what Timmins Gold is mining at the San Francisco Mine and Sierra Minerals is mining at the Cerro Colorado Mine 150 km away.
On the Tajitos Project, the principal structural vein system is trending N55W with a secondary system trending N20W, both within an altered volcanic and sedimentary Jurassic and Pre-Cambrian sequence similar in structural orientation, mineralization style and host lithologies to the Herradura Mine (Minera Penmont) and the El Chanate Mine (Capital Gold) both of which are within 100 km of the Tajitos Project and are accessed by the same paved interstate highway and other infrastructure. The Tajitos vein system is exposed over 2 km on surface and trends SE and under cover on to the adjoining Tejo Concession that is wholly owned by Riverside Resources.

The project has been held in private hands for over 30 years and was subject to a drill program in 2008 by Minera Penmont. The drill program consisted of three holes (TJC-002, 006 and 008 for a total of 529.83 metres) which were drilled within the Riverside property boundary that encountered encouraging results, including: 2.03m grading 15.3 g/t gold in the vein system and 8.12 metres grading 1.8 g/t gold of disseminated mineralization (including a second interval of 2.03m grading 6.57 g/t gold in the vein shears).
