The Yoreme Property is situated in the Alamos Mining District in southern Sonora State, Mexico, and consists of one mineral claim, located approximately 14 kilometres west of the city of Alamos. The 400 hectare property covers the San Manuel silver-lead-zinc vein and is located at 22°49'23"N and 102°34'51"W. Numerous large scale producing mines occur within the area, the closest are the Piedras Verdes Mine (Rio Tinto), located 20 km to the northeast of Yoreme and the Alamo Dorado Mine (Pan American Silver) located 47 km southeast of Yoreme.
History
The San Manuel vein is the south-western most structure in the Alamos Mining district -- one of the oldest mining districts in Sonora, located in the western foothills of the prolific Sierra Madre mineralized belt that extends from Arizona through northern Mexico. The property has had small scale (approximately 3000 tonnes), historic exploitation of Silver-Lead-Zinc ore from three shafts and a surface cut on the San Manuel Vein.
Purchase Agreement
Silver Sun Resource Corp. has acquired one hundred percent (100%) right, title and interest in the Yoreme mineral claim.
Geology
Mineralization observed on the Yoreme Project property consists of polymetallic fissure fill veins and breccia structures occurring in the historic San Manuel Vein. The San Manuel structure trends northeast, parallel to numerous structures that host fissure fill mineralization and can be traced over 500m ranging from 1.0 to 2.1m wide. The fracture fill mineralization is hosted in granodiorites of the coast intrusive batholith. Mineralization consists of quartz carbonate veins and hydrothermal breccias within a well defined structure. There is limited wall rock alteration in the host granites, and silver mineralization occurs with galena and associated sphalerite within the vein matrix. The Yoreme claim is located on trend with the major silver mineralized structures with grades from mineralized outcrop in historic working ranging from 250.0 g/t to 1825.0 g/t silver.
Work Programs
Phase I exploration work began in December 2010 and consisted of trenching, dewatering and rehabilitating of historic workings with rock chip sampling of the trenches and underground workings.
The recommended Phase II is planned to consist of a multi-level, shallow diamond drilling program to intercept the interpreted higher grade silver ore shoots. The initial drill targets recommended are located below the known historic workings to test the down dip continuity of the exploited higher grade zones.
Initial sampling performed by Company's Mexican subsidiary Minera Plata del Sol S.A. de C.V. retuned the following values:
| Sample | Type | Width (m) |
Ag (g/t) |
Pb (%) |
Zn (%) |
|---|---|---|---|---|---|
| 37459 | Rock | 2.0 | 569.3 | 1.63 | 6.04 |
| 37460 | Dump | - | 1,259.6 | 0.97 | 2.61 |
| 37461 | Rock | 2.0 | 1,768.6 | 0.29 | 0.74 |
| 37462 | Rock | 1.0 | 82.7 | 0.05 | 0.51 |
| 37464 | Dump | - | 85.9 | 2.02 | 2.62 |
| 37465 | Rock | 1.0 | 1,825.7 | 0.18 | 0.31 |
Follow-up sampling performed in conjunction with a technical report returned:
- 256.0 g/t silver over 1.96 m;
- 262.0 g/t silver over 1.8 m; and
- 126.0 g/t silver over 2.6 m
