Endeavour Silver Options Lomas Bayas Silver-Gold Property in Chile; Third Quarter Earnings Report to be Released on Wednesday November 2rd; Teleconference on Thursday November 3th

By: Endeavour Silver Corp.

-- Posted 19 October, 2011 | |

VANCOUVER, BRITISH COLUMBIA--(Marketwire -10/19/11)- Endeavour Silver Corp. (TSX: EDR.TO)(NYSE: EXK)(Frankfurt: EJD.F) announces that it has acquired an option to purchase the Lomas Bayas silver-gold property in the Copiapo region of northern Chile.

This marks the second prospective silver-gold property Endeavour has acquired in the Copiapo region, following the acquisition of the La Presidenta property one month ago. Both properties have histories of small scale silver mining and both appear to be prospective for the discovery of bulk tonnage, low grade epithermal silver-gold mineralization in a volcanic caldera setting.

Like La Presidenta, Lomas Bayas (407 hectares) is located approximately 55 kilometers (km) southeast of the city of Copiapo in gentle terrain at an elevation of 2000 meters (m) above sea level, and is readily accessible from Copiapo about a one hour drive on paved and gravel roads. The property also enjoys excellent infrastructure, being located within 10 km of the Copiapo River and the state power grid.

Silver and gold were mined historically by underground methods from several shafts up to 330 m deep. More than 30 sub-parallel veins, typically less than 1 m thick, occur over a 300 m wide zone that can be traced for up 1500 m. Historic mine grades were reported to be in the ranges of 50 to 1000 grams per tonne (gpt) silver and 1 to 20 gpt gold. Chip samples of vein wall-rocks collected by Endeavour personnel returned assays ranging from 1 to 351 gpt silver and 0.08 to 31.7 gpt gold.

The main targets for exploration are the thicker but lower grade zones of wall-rock breccias, sheeted vein-lets and stock-works left behind by the old miners. These zones are up to 80 m thick and 300 m long. Because ownership was fragmented for many years, no modern exploration work or drilling has ever been carried out at Lomas Bayas.

Silver-gold mineralization in the oxide zone down to a depth of more than 100 m is associated with iron oxides, calcite and quartz. Bottle roll cyanide leach testing of oxide samples averaged a 95% recovery for silver and 99% recovery for gold, indicating that the oxide mineralization should be heap leachable. In the sulfide zone below 100 m depth, silver and gold are reported to occur in native form and with sulfides such as argentite, stephanite, stromeyerite, sphalerite, galena and pyrite.

Endeavour can acquire a 100% interest in Lomas Bayas for cash payments totaling US$2,500,000 over a eighteen month period followed by a final cash payment ranging from US$10 to $15 per ounce of gold equivalent reserves and resources (with silver as the only equivalent) as estimated in an independent NI 43-101 report on the property within 24 months of signing the agreement.

A Phase 1, 50 hole, 10,000 meter reverse circulation drill program is now underway to test the thicker but lower grade zones of wall-rock breccias, sheeted vein-lets and stock-works along strike and down dip within the historic mineralized areas at Lomas Bayas.

Barry Devlin, Vice President Exploration for Endeavour, commented: "Lomas Bayas represents not only an exciting early-stage opportunity, it is a bulk tonnage, low grade silver-gold prospect that gives Endeavour more critical mass as we build our exploration property portfolio in Chile. We think the silver mining potential of northern Chile is significantly under-explored and we are actively pursuing the acquisition of other interesting bulk tonnage silver prospects at this time."

Barry Devlin, M.Sc., P.Geo., Vice President, Exploration is the Qualified Person who reviewed the historic technical information for this news release and supervised the site visit and rock sampling of the La Presidenta property. A Quality Control sampling program of reference standards, blanks and duplicates has been instituted to monitor the integrity of all assay results. All samples were shipped to ALS Minerals Labs, where they are dried, crushed, split and 30 gram pulp samples are prepared for analysis. Gold is determined by fire assay preparation with an atomic absorption (AA) finish, silver by four acid digestion followed by AA and other elements are determined by either AA or Induced Coupled Plasma (ICP) analysis.

In addition, the Company will release its Third Quarter 2011 financial results on Wednesday November 2nd, 2011 after the close of the market.

A conference call to discuss the results will be held at 10:00 AM Pacific Time (1:00 PM Eastern Time) on Thursday November 3rd, 2011. To participate in the conference call, please dial the following:
