Yale Resources Ltd. - La Verde Project

Location:

La Verde Project is located in central Sonora State, approximately 50 km northwest of the city of Hermosillo.

Deposit Model:

Copper-silver-zinc-gold skarn with associated porphyries.

Ownership:

100% Yale Resources Ltd.

Size:

The La Verde Project is 2,940 hectares (29.4 km² or 7265 acres) in size.

Status:

Available for Option or Joint Venture.

Summary:

La Verde Project is an early to mid stage exploration project with start up copper and silver production potential at the La Verde Grande Mine. Underground sampling at La Verde Grande in the last two years has defined a mineralized body that remains open along trend.

There are records documenting production within the property for over 100years. The most advanced target is the La Verde Grande Mine which has seen historic production from high grade copper and silver skarn mineralization. In addition several other occurrences have been exploited and a non NI 43-101 compliant resource estimate for La Verde Grande was completed.

The continuity of copper-silver skarn mineralization can be defined through geological mapping along projected trends and tested with diamond drilling. Work to define an open pittable resource at La Verde Grande Mine would consist of delineation drilling.

Geology:

The project is located at the western edge of the Arizona-Sonora porphyry copper belt. Porphyry copper deposits, some with associated skarn mineralization, within this district include Cananea, La Caridad, El Creston and El Tecolote.

Skarn mineralization within the La Verde property consists of a series of structurally controlled bodies and fault/breccia zones. Host rocks are a thick sequence of metamorphosed limestones that are locally intruded by granite and granodiorite porphyries, dykes, and historic records mention mineralized aplite dykes.

Copper-silver-zinc-gold mineralization appears to be spatially associated with the granodiorite contact. Structurally, the area has been affected by folding and faulting both on a regional and property scale, which created a northwest-southeast trending antiform through the central portion of the property that hosts the majority of the known skarn deposits. Tertiary felsic volcanics and volcanic agglomerates comprised of rhyolite flows and tuffs overly the sedimentary sequence in the northern portion of the project while Tertiary basalt flows overlie the sediments in the central and southern portions of the project.

Skarn and breccia mineralization at La Verde Project consists predominantly of copper oxides including malachite, chrysocolla and chalcocite. There are historic reports describing sulphide mineralization below the known extent of the La Verde Grande mineralized skarn body.

Preliminary leach tests and historical metallurgical tests of the skarn ore indicates that recoveries of copper, silver and zinc are good with average test recoveries for silver by floatation of approximately 80%, and copper and zinc through acid leaching of approximately 86% and 76% respectively.

Results:

La Verde Grande:

As with all skarn deposits there is a variation in the grades throughout the deposit. Of particular note is the exceptional grades encountered in the lower level: the 11 samples averaged 3.04 % copper and 190.0 g/t silver over 50 metre length of the working.

La Tescalama

Skarn mineralization exposed in the tunnel at La Tescalama has many similarities to that within the La Verde Grande Mine. To date the deposit is open in all directions as all of the workings are within mineralization. Below are the complete results from the first phase of sampling:
