Arco's Additional Claim at Tres Hermanas Approved

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 20, 2010) - Arco Resources Corp. (TSX VENTURE:ARR) ("Arco" or the "Company") is pleased to announce that the General Direction of Mines in Mexico has approved the titling of Arco's Khulan claim as part of its Tres Hermanas claim block. The Khulan claim consists of 2,271 hectares located in the Rio Dulce district of Oaxaca, Mexico. The Tres Hermanas claim block now consists of the Khulan claim as well as the Tres Hermanas 1 and Tres Hermanas 2 claims, which have areas of 500 and 900 hectares respectively.

The 3,710 hectare Tres Hermanas property is 100% staked and owned by Arco, and covers a silver-lead-zinc-bearing vein system that has historic underground workings on five levels along a 400 metre strike. Previous sampling underground shows local values >500 g/t silver. In addition, chip samples taken included values as high as 764.5 g/t silver and 10.4% lead across 1.5 metres. Regional soil sampling has indicated the vein system continues along strike in both directions. The vein system shows widths of one to two metres with a lower grade shell upwards of 15 metres.

Correction on Finders' Fees Paid

Arco also wishes to correct the finders' fees that were reported to have been paid in connection with its non-brokered private placement, which closed on March 29, 2010. That private placement consisted of a total of 25,830,000 units (the "Units") at the price of $0.05 per Unit. Each Unit consisted of one common share of the Company ("Share") and one share purchase warrant ("Warrant"). Each Warrant entitles the holder to purchase one Share at an exercise price of $0.10 per Share for a period of two years from the date of issuance of the Warrant. Arco issued a total of 1,968,000 finders' warrants (rather than the 1,418,000 finders' warrants reported in our April 1st news release), and paid a total of $75,300 in cash (rather than the $54,675 in cash reported in our March 25 and April 1st news releases).
