Project Locations & Significant Deposits

Pediment currently holds twelve fully owned projects and two optioned project and reconnaissance work continues to assess and acquire more. The primary focus of this work has been gold and silver targets with an emphasis on the still evolving "orogenic" deposit model. Orogenic gold deposits are a recently recognized grouping or deposit model type resulting from deposition of gold and/or silver into amenable host rocks by fluids streaming from areas of intrusive activity. This is an important new class, as it includes many of the world's largest gold deposits.
Pediment has properties in strategic regions in northwestern Mexico:
In the Baja California Sur, the San Antonio gold district hosts a number of gold deposits totaling several million ounces of gold. Pediment's San Antonio gold project is located east-southeast of La Paz beyond the northern termination of a series of mountain ranges. The deposit is typified by the nearby two million ounce Paredones Amarillos gold deposit owned by Vista Gold.
In Sonora, Pediment's decision to option the La Colorada Gold-Silver mine project is based on developing a modified geological model for the formation of the vein and stockwork deposits. La Colorada was until recently Sonora's largest historic gold producing mine.
The Mojave-Sonora Megashear gold-silver belt (MSM) hosts several significant gold mines including La Herradura, a joint venture between Industrias Penoles (56%) and Newmont Gold Corp (44%) that is producing at a 180,000 ounce/annum rate at a total cash cost of US$254/ounce (Newmont). Pediment holds eleven prospective projects in the MSM trend which are targeted for the exploration of bulk tonnage gold deposits similar to La Herradura: the Daniel, Manuel/Mel, Cochis, Glor, La Cien, Caribe, Nopal, Roja gold targets and the Texson silver-gold project and the Caborca copper-gold target.
The Mega-Shear trend (or Belt) is a fold --thrust belt deforming Mesozoic aged volcanic and sedimentary rocks and Precambrian gneiss and granite. Gold and/or silver mineralization is localized where metal bearing fluids channeled by low-angle shear zones intersect high-angle structures. Another significant gold mine already in this belt is the Mesquite and it has produced 3 million ounces from approximately 5 million ounces outlined and is currently operated by Western Goldfields Inc.
The Sierra Madre Occidental gold-silver belt in the Mulatos district has seen recent discoveries by Grayd Resources and hosts the producing Mulatos gold mine owned by Alamos Gold. Large resources of stratabound high-sulfidation gold mineralization are being developed by Alamos and recently by Grayd Resource. Pediment's Valenzuela property is located in this highly prolific belt.
