Focus Makes New Discovery at Reventon: 98 g/t Ag over 24m in Trench


VANCOUVER, Oct. 30, 2012 /PRNewswire/ - Focus Ventures Ltd. (TSX-V: FCV) is pleased to announce assays from initial channel sampling at its Reventon property within the Santa Cruz project. Prospecting and sampling has confirmed high-grade silver mineralization associated with multiple zones of hydrothermal breccias in areas of strongly anomalous silver-in-soil geochemistry (see press release dated 11 October 2012.)

David Cass, President of Focus, comments: "These initial assays from follow-up of the strong silver anomalies generated by our soil sampling program are very encouraging; in particular the discovery of several new mineralized breccia zones. We are very pleased with progress to date and look forward to more results as our surface sampling and trenching program advances."

The Chicle Zone lies approximately 250m west of the Estrella Mine and 2km southwest of the drilled Reventon Breccia and appears to be one of several mineralized epithermal structures in addition to those sampled at La Estrella, El Taco and Cordon. Recent work along a pronounced north-west trending ridge has revealed a +20m wide zone of hydrothermal brecciation in sericitized and chloritized andesites. Initial rock sample results, which range from trace to 610g/t Ag and trace to 0.68g/t Au, have validated the strong silver-in-soil geochemical anomaly. The silver mineralization is associated with quartz and arsenopyrite. At El Taco, located 100m to the south-east of the La Estrella Mine, sampling along the walls of an old pit assayed 165 g/t Ag, 0.32 g/t Au over 8.9m. Maps and plans are available on the company website

Bellota, Potreros and Camino Real Areas

Follow-up trenching of a soil anomaly some 100m south of the Bellota occurrence has discovered a new north-east trending mineralized zone in weakly silicified andesite that assayed 98.3 g/t Ag over 24m. This likely represents satellite mineralization to the Reventon breccia where drilling in 2007 and 2008 by International Northair Mines Ltd cut breccia-hosted silver, zinc and lead in the majority of holes drilled, including 155.4m @ 71.3 g/t Ag, 0.46% Pb and 0.61% Zn (Hole RC-08-8) and 22.9m @ 287 g/t Ag, 1.39% Pb and 3.48 % Zn (Hole RC-08-13).


The Santa Cruz and El Reventon properties lie within the Silver Lake Trend, a polymetallic belt that hosts several operating and past producing gold and silver mines, including the La Ciénega, Topia, San Dimas and Metates deposits. Focus controls a major district-scale land position comprising over 60,000 hectares covering a mineralized trend over 20km long. Since late 2011 exploration by Focus has resulted in the definition of several breccia-hosted silver and gold targets within the trend that show potential to host bulk-tonnage high-grade and low-grade deposits, with permitting for drilling currently underway. Exploration is continuing at Reventon with remaining soil anomalies being followed up and trenched.

Sampling Quality Analysis and Quality Control

Rock samples were prepared at ALS Chemex's preparation facility in Zacatecas and analyzed in Vancouver, Canada.  Silver was determined by multi-acid digestion and ICP-AES, with fire assay gravimetric finish. Gold was assayed by Atomic Adsorption Spectrometry with fire assay gravimetric finish.  Lead and zinc were determined by ICP with Atomic Absorption with volumetric finish.  ALS Chemex's quality control system complies with International Standards ISO 9001:2000 and ISO 17025:2005.  Analytical accuracy and precision are monitored by the analysis of reagent blanks, reference material and replicate samples.  Quality control is further assured by Focus's own QA/QC program which involves the insertion by Focus personnel of blind certified standards and blanks into the sample stream at regular intervals in order to independently assess analytical precision and accuracy of each batch of samples as they are received from the laboratory.
