Epithermal gold-silver adds another dimension at Bahuerachi

Vancouver – Calgary-based Tyler Resources (TYS-V) has intersected epithermal-style gold and silver mineralization at the Los Alisos zone on its Bahuerachi copper project in the La Reforma region of Mexico’s Chihauhau state. Los Alisos is situated some 1.2 km west of the Main zone which has been the focus of the company’s drilling and previous work on the property.

The Main zone, extends for more than 4,000 metres of strike length, over widths varying between 200 and more than 700 metres.

Tyler tested the Los Alisos epithermal system by first pass reverse circulation (RC) drilling. Holes RC-8 and 9 intersected bonanza style mineralization whereas Holes RC-10 and 11 intersected weak mineralization.

Hole-8 intersected 7.62 metres grading 3 grams gold and 34 grams silver with 0.53% zinc from a depth of 16.7 metres that included 1.5 metres of 9.84 grams gold and 18.6 grams silver and 0.94% zinc.

Hole-9 returned 9.14 metres of 2.18 grams gold with 822 grams silver from 22.8 metres down hole, and 12.2 metres of 2.7 gram gold and 38.7 grams silver with 1.57% zinc from 35 metres depth.

Holes RC-8 to 11, were drilled across the main veins along fences 50 metres apart. The holes all intersected strong quartz vein and veinlet stockwork zone alteration in a coarse grained, altered porphyritic rock. The stockwork zone was outlined over 50 metres by 30 metres and to 65 metres depth.

Meanwhile, Tyler continues to test the Main zone with core hole 05-BAH-20 currently turning.

Three distinct but related domains of mineralization have been identified at the Main zone. The first comprises low-grade copper mineralization in an enriched oxide blanket within rocks hosting the main intrusive complex. The second consists of extensive, high-grade breccia and skarn complexes on the fringe of the main porphyry, while the third consists of low-grade stockwork and the mineralized intrusive porphyry.

Tyler wants to continue to use RC drilling to test the mineralized zones on the property and is comparing twin assay results for hole RC-6, with diamond drill hole 05-BAH-15. The company believes that the assay results from RC holes grade lower when compared with the core assay results.

Results are pending for RC-12 and 13 that tested the skarn mineralization in the northwestern part of the property.
