Arco Intercepts 3.7 Metres of 307 g/t Silver and 1.02 g/t Gold at Taviche

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 24, 2010) - Arco Resources Corp. (TSX VENTURE:ARR)(FRANKFURT:MJ7) ("Arco" or the "Company") is pleased to announce results from diamond drill holes 5 through 8 of the recently completed drill program on its 100%-owned Taviche property located in Oaxaca, Mexico. Taviche is a silver-gold-bearing quartz vein traced for over 1.5 kilometres with typical epithermal textures and existing historic (Spanish and subsequent) underground workings. The recently completed program is the first surface drilling to have ever been conducted on this vein. Highlights from holes BDT-5 through BDT-8 include 3.7 metres of 306 g/t silver (Ag) and 1.02 g/t gold (Au) or 367 g/t silver equivalent (AgEq), including a 0.70 metre interval of 738 g/t AgEq.

*True widths are estimated to be roughly 65% of drill intercept length.
**Arco used the silver equivalent ratio of 1 gram of gold = 60 grams silver assuming 100% recoveries.

Standard, blank, and duplicate samples were inserted throughout the sample sequence as quality control checks. Samples were analyzed by Acme Analytical Labs. Samples were analyzed by Aqua Regia digestion with ICP-MS analysis. Overlimit silver values were re-analyzed by Aqua Regia digestion with ICP-ES finish. Overlimit silver >300 g/t were re-analyzed by fire assay on 30g sample with gravimetric finish. Paul Cowley, P.Geo. and Chief Geologist for Arco, is the Qualified Person, as defined in National Instrument 43-101, for the drilling campaign and has reviewed and approved the technical content of this news release.

Taviche Property

The Taviche property covers 421 hectares and is located approximately 68 kilometres from Oaxaca City, Mexico. Access to the property is excellent, less than 1 kilometre from paved road and a 1.5 hour drive from the capital of Oaxaca. On Taviche, the sub vertical laterally continuous silver-gold-bearing quartz vein varies in thickness from 1 to 5 metres, averaging 2 metres. Epithermal textures include open space fillings, bladed veining and megacrystic carbonate replacement, all significant textures known in gold-silver epithermal deposits. Of the 1.5 kilometre long trace, the vein has received 500 metres of historic continuous underground workings on one level. Underground channel sampling defined a 230 metre long shoot of the vein with values averaging 173 g/t Ag and 1.5 g/t gold Au. Corresponding surface sampling approximately 15 metres above the underground workings identified a 220 metre long shoot averaging 161 g/t Ag and 2.18 g/t Au.
