  |     Sierra Madre Occidental Range, Largest Epithermal Precious Metals Region in the World; Immense Potential for Resource Companies By James O'Rourke - May 16, 2008            Investors in resource stocks should be aware of the significance the Sierra Madre Occidental Range in western Mexico presents for exploration companies. Home to large multi million oz gold and silver deposits,companies such as Minefinders, Alamos Gold, Gammon Lake, Goldcorp, Agnico-Eagle, among others, are active in this geological region considered to be  the  largest epithermal precious metals region of the world. With production from the area of approximately 40 million ounces of gold and up to 2 billion ounces of silver over the last 400 years the, Sierra Madre Occidental Range has become an areaof global focus in the search for new precious metal deposits. This  presents tremendous opportunity for exploration/mining companies and their respective shareholders.  | |

The regional distribution of epithermal deposits in Mexico, as well as deposits belonging to other deposit types (Sn veins, skarns, etc.), indicates they are closely associated in space with regional faults. The mostprolific region is that of the Sierra Madre Occidental, a mountain range in western Mexico and the extreme southwest of the United States which extends 1500 km from southeast Arizona (south and east of Tucson) southeast through eastern Sonora, western Chihuahua, Durango, Zacatecas, Aguascalientes to Guanajuato, where it joins with the Sierra Madre Oriental and the Eje Volcánico Transversal ofcentral Mexico. These mountains are generally considered to be part of the much larger American cordillera.   Full version of this report has expanded insight into the geological interpretation of the Sierra Madre Occidental and notable participants in the region. This is the abridged version, however information mirroring the geological interpretation described may be viewed here. |

  Contentfound herein is not investment advise see Terms of Use, Disclosure & Disclaimer   Immense potential exists for resource companies with strategic holdings within the Sierra Madre Occidental belt   Case Study Yale Resources Ltd. (TSX-V: YLL) Yale Resources' Urique Project is in close proximity to neighbouring large established resource laden gold and silver projects that share the samestratigraphy. It is not unreasonable to expect Yale to have a major gold-silver find in its future considering what they already know of the surface grades, geophysics, history, neighbours, location and size of Urique.
 
Yale's Urique Project, in the highly prolific Sierra Madre Gold Belt, boarders Goldcorp's El Sauzal Mine (2.1M oz Au) to the south and Kimber Resources' Monterde Mine (0.8M oz Au, 45M Ag)to the north. Yale has identified quality targets at the Urique Project related to large mineralized hydrothermal systems that have the potential to host bulk mineable resources.
 
Numerous plus-one million ounce gold deposits have been discovered in this 300 km long region of southwestern Chihuahua: including Mulatos (Alamos Gold - proven & probable reserve of 2.1 mill oz gold, 268,000 ozgold mined: Q3 2005 -- Dec 31, 2006), Dolores (Minefinders - 3.7 mill oz gold measured, indicated & inferred), Ocampo (Gammon Lake - 4.4 mill oz gold measured, indicated & inferred ), as well as the El Sauzal mine (Glamis Gold, now part of Goldcorp Inc.) and Palmarejo-trogan (Coeur d'Alene, 1.14 mill oz gold measured, indicated and inferred).   Yale has a monstrous 290 Sq km property withover 30 previously mined locations on the property. Historic workings are from the periods stretched over 400 years of mining history on the property (dating back from the Spanish to the early 1900’s, and 50’s, 60’s). The old timer’s technology dictated they could only take the highest grade material - from a mining standpoint to the recoveries, recoveries being key; they typically only dealt...
