Silvermex Begins Surface Drill Program at La Guitarra
Vancouver, BC, Canada - September 26, 2011 - Silvermex Resources Inc. ("Silvermex") (TSX: SLX) announces the commencement of a surface diamond drill program on the La Guitarra property, located in the Temascaltepec Mining District in the State of Mexico. The program is planned for a minimum of 7,500 m of HQ diameter core drilling.
Initially, drilling will focus on the Coloso Area approximately 3 - 5 km to the northwest of the operating La Guitarra Mine. The objective of the drill program is to further test the known Jessica and Nazareno structures in addition to other structures in the area, including Joya Larga, Comales and Coloso. Geological mapping, rock chip sampling and soil sampling were completed prior to the drill program, with analysis using Mobile Metail Ion ("MMI"), a proprietary selective leach assay method developed by Wamtech Pty of Australia and under license to SGS Laboratories in Toronto, Canada. The MMI results identified previous unknown potential strike extensions to the known mineralized structures and identified new structures to be drill tested.
Three holes have been completed on Jessica, which is known to host at least two silver and gold bearing quartz veins over a minimum strike length of 250 m. Each hole has encountered two quartz veins varying from 0.8 -- 1.2 m in width within mafic to intermediate volcanic tuffs and breccias. These veins are interpreted as being similar to the main Jessica Vein and the Footwall Vein. The current drill program is following up on previous drilling by Genco Resources Ltd. ("Genco") reported in a news release dated March 26, 2008 entitled "Genco Discovers Significant Mineralization through Reconnaissance Drilling", which had returned several significant intercepts including:
- 1.0 m of 2.50 g/t Au and 1030 g/t Ag from 84 -- 85 m in hole GDH-180; and
- 0.80 m of 1.22 g/t Au and 1070 g/t Ag from 55.80 -- 56.60 m in hole GDH-182.
Check assaying by Genco confirmed grades and widths. Core logging and assaying by La Guitarra geological personnel is in progress.
A second important target area, Nazareno, has been drilled by previous operators and has been investigated by a series of adits at different elevations. The most important working is a 55 m deep shaft/open stope on a zone of high-grade silver mineralization. Significant gold and silver values are reported by previous operators. The proposed drill program will aim to verify the previous intercepts and test down dip and along-strike potential.
Nazareno remains open along strike to the northwest for at least 1 km. This section has never been drill tested, however MMI analysis of soils identified a potential strike extension with a stronger geochemical response than in the area of known mineralization. Both the main Nazareno Area and its potential strike extension will be drill tested.
A third target to be drill tested is known as the Joya Larga Vein. It has been traced on surface over a strike length of at least 900 m. It was delineated by identifying small outcroppings, old excavations and, occasionally, quartz float. It consists of milky quartz locally banded with an average width of 1.2 m. Nearby there is breccia present with strongly argillized and silicified fragments of tuffaceous volcanic rocks. Pyrite and marcasite is present in places. There is a strong multi-element soil anomaly directly associated with most of this structure. Of note is that previous drilling has never tested the portion of Joya Larga which exhibits the significant geochemical response. A fourth target area occurs within a large incised valley between Nazareno and the Los Angeles Area of the La Guitarra Mine where a very large MMI soil anomaly has been identified. This is a very strong multi-element response with high soil values in gold, silver, arsenic, antimony, mercury and thallium. Geological mapping is in progress and significant amounts of arsenopyrite, marcasite and pyrargyrite have been identified in surface exposures. This mineralogy is similar to that of the adjacent La Guitarra Mine. Drilling will be undertaken once all results are available and interpreted.
A number of other vein structures with multi-element soil responses to be drill tested occur in the Coloso Area. These include Comales, Veta Coloso, Nazareno 1, Nazareno 2 and Veta Soledad. One drill is currently on site and a second drill is to be mobilized by the contractor in mid-October. Drilling is expected to continue into next year
