Regency Silver’s drilling results from from holes at its Dios Padre project in Sonora returned some excellent gold grades and good copper over long intervals. The intercepts are on sulfide bearing breccias that are common in the Santa Rosa de Yecora district in Sonora. The breccias are complex, present in many shapes and developed in the intrusive rocks, or more commonly, in the contact with the hosting intermediate volcanic rocks package. Other breccias in the district host copper-molybdenum, gold or silver resources, and at least in one property gold is being currently mined.

The Evelyin project is also in Sonora and is being explored by Colibri Resource. Gold mineralization is of orogenic style, and the company has been drilling several targets with a strong structural component, as is usual in this type of deposits. Undercover mineralization is being pursued also by drilling short holes to bedrock on the extensive cover present in the area.

Oroco Resource presented a corrected set of results for one hole from its Santo Tomás porphyry copper project in Sinaloa, previously released last week.
