Drill Results & Exploration Update For Tajitos Gold Project 

 

VANCOUVER, BC - Riverside Resources Inc. reported drill results and an update on exploration work at the Company's Tajitos Gold Project, located in Sonora, Mexico. Core and reverse circulation (RC) drilling has concluded and Riverside has now received gold assay results for all samples submitted to the lab. Riverside and partner Centerra Gold Inc. completed eight diamond core holes totaling 1,832 meters. Highlighted intercepts from the core drilling included (reported intervals are approximate true width): T16-001D, 3.00 meters @ 1.14 g/t gold starting at 297.00 meters depth ?(hole ended in mineralization); T16-002D, 11.10 meters @ 0.78 g/t gold starting at 185.90 meters depth; T16-005D, 3.00 meters @ 6.12 g/t gold starting at 48.00 meters depth; and T16-008D, 1.50 meters @ 6.03 g/t gold starting at 42.00 meters depth. 

Mineralization intersected in the Tajitos drilling correlates with fault zones and lithologic contacts and further drilling is required to determine the mineralization extent and tenor. Initial evaluation of trace elements from 6 of the holes and surface sampling show an enrichment in As, and Sb within the gold zone and in the footwall below gold enriched zones. Lead is also elevated in the areas with the highest gold values. This pattern was also seen in previous trench and channel sampling. Patterns of trace and base metals will be examined with regard to future drill targeting and multi-element vectoring to gold zones. The core drilling at Tajitos provides key structural and stratigraphic information permitting updated fault control modeling and detailed investigation of alteration patterns and paragenesis of the gold mineralization. 

Riverside's President and CEO, John-Mark Staude, said, "The Sonora Orogenic Gold Deposits commonly have lenses of gold and often require several drilling campaigns and several dozen drill holes for a major discovery. We are encouraged with the results of this initial phase of 8 core holes, which will help us establish a better understanding of controls on mineralization and guide future drilling and exploration efforts at Tajitos."

A program of reverse circulation drilling in the Tejo area was designed to determine the depth to bedrock and 1,728 meters were completed in 12 holes. The Tejo drilling determined depth to bedrock ranges from a few meters to over 200 meters deep. The intersected bedrock includes the same stratigraphic units which host gold mineralization at the Tajitos target and similar alteration is observed in both areas. The minimal bedrock sampled only contained trace levels of gold but trace elements will be further evaluated to determine possible zoning patterns to vector toward the most favorable areas and will be used in conjunction with surface mapping and geochemical sampling.
