M A R K E T W I R E - - - August 08, 2011 10:45 ET - - - Alto Group Holdings, Inc. (OTCBB: ALTO) ("Alto Group" or the "Company"), an innovative mining and commodities trade company headquartered in Florida, announces the company has expanded the excelsior mining project. The company has recently expanded the Excelsior project by staking an additional 30 claims within the project which now brings the total amount of mineral claims owned to 60 overall. This increase has been completed to further expand the resource potential of these mineral holdings in preparation for the work to update a resource estimate which begins this week on location within the state of Washington. The Great Excelsior Mine was a former gold-silver producer which was forced to close in 1918 due to falling metal prices and a shortage of supplies. Alto Cascade Resources, which is 51% owned by Alto Mines, recently located 60 lode mining claims covering the drilled resource. This mining property has been explored by numerous mining companies over the years, including ASARCO, Silver Standard, Ltd., Quintana Resources, Inc., US Borax, Steelhead Resources, Inc, FMC Gold Corp., Stanford Metals, Ltd, and Arizuma Silver, Inc. In 1987 Steelhead Resources commissioned American Mine Services, Inc. (AMS), to calculate the global geologic reserves and stripping ratio for the deposit. This calculation was done using geostatistical methods and based on the assay results from 45 core holes drilled by US Borax, Corp. AMS concluded that the project could be mined using a 3:1 stripping ratio. M A R K E T W I R E - - - August 08, 2011 10:45 ET - - - Alto Group Holdings, Inc.
