Arco Resources Corp. (TSX VENTURE:ARR)(FRANKFURT:MJ7) ("Arco" or the "Company")
is pleased to announce results from the remaining seven holes of the recently
completed diamond 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 and has tested a 450
metre-long strike length of the vein to date. Highlights from holes BDT-9
through BDT-15 include 2.7 metres of 220 g/t silver (Ag) and 0.85 g/t gold (Au)
or 271 g/t silver equivalent (AgEq).

(i) True widths are estimated to be roughly 65% of drill intercept length.
(ii) Arco used the silver equivalent ratio of 1 gram of gold = 60 grams
silver assuming 100% recoveries.
"We are very encouraged with the consistently elevated silver and gold values
along the 450 metre strike length so far tested by this drill program. The
silver-gold system remains open to the east, west and at depth. Next week, our
technical group will provide a geological summary that pulls all of these
results together to give it proper context. We intend to continue drilling on
the system as promptly as possible," says Warren McIntyre, President of Arco.
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 greater than 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 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.
About Arco Resources
Arco holds a 100% interest in seven mineral claim blocks, all located in the
State of Oaxaca, Mexico. The Company has begun to focus its efforts on its
Taviche and Predilecta claim blocks, each of which has had historical production
of gold and silver. The Company currently has agreements in principle to option
100% interests in its Lachiguiri, Silacayoapan and Nino Perdido Property (to
Silex Ventures Ltd.) and in its Tres Hermanas Property (to Zodiac Capital Ltd.).
