Arco Intercepts 7.9 Metres of 193 g/t Silver and 1.27 g/t Gold at Taviche Property

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 21, 2010) - Arco Resources Corp. (TSX VENTURE:ARR) ("Arco" or the "Company") is pleased to announce the results from the first four of the 15 diamond drill holes recently completed 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 the first four holes include 7.9 metres of 193 g/t silver (Ag) and 1.27 g/t gold (Au) or 269 g/t silver equivalent (AgEq), including a 2 metre interval of 480 g/t AgEq.

* Arco used the silver equivalent ratio of 1 gram of gold = 60 grams silver.

Standard, blank, and duplicate samples were inserted throughout the sample sequence as quality control checks. Samples were analyzed by Acme Analytical Labs. 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.

"These first results confirm what we had identified underground," said Warren McIntyre, President of Arco Resources. "This program only covers 350 meters of the vein and the old workings. The potential for expansion of the system to the west is Arco's next priority. In addition, the depth of the intercepts confirms that we have identified a system underneath the old workings. All of these are great indicators of the potential of this property."

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.
