Focus Starts Work at Chúcara and Confirms High-Grade Assays
|April 29, 2010; Vancouver, Canada: Focus Ventures Ltd. (TSX-V: FCV.V) is pleased to announce that field work has started at its Chúcara gold-silver project located in the La Libertad gold mining district in north-central Peru (see press release March 5, 2010). The 700 ha project is located some 45 km southeast of Barrick's Lagunas Norte Mine and 18 km east of the Comarsa Au-Ag Mine, and covers the majority of the historic Chuvilca Ag-Au (Pb-Zn) mine workings and the south-eastern extension of the mineralization. |
The planned work will involve geological mapping, aerial photography, mineral mapping, surface and underground sampling. Focus is also permitting a drill program planned for August 2010, consulting with local communities, and working on an environmental base line study required for the drill permit.
Focus Confirms Historical High Grade Assay Results
A total of 83 samples of coarse reject material from the historical sampling that assayed >100 g/t Ag were retrieved from storage and re-submitted for analysis in order to determine the exact quantity of silver and confirm the previous assays for gold. The samples were collected by previous operators of the project from veins, mantos and wallrocks over a 1.4km strike length of the property.
The 83 samples averaged 7.3 g/t Au and 314 g/t Ag and confirm the high grade Au and Ag values from the historical sampling and the reproducibility of the historic assays. The minimum and maximum sample widths were 0.2m and 5.3m respectively, with an average sample width of 1.43m. The reader is cautioned that as these samples are a selection of the highest grade samples collected to date, they do not adequately represent the average grade of the mineralization.
Summary of Assay Results (83 samples)
High-grade gold and silver vein mineralization at Chúcara occurs as swarms of en-echelon veins and mantos within a north-northwest trending structural corridor at least 2 kilometres in length. Gold and silver mineralization is characterized by a strong association with Pb, Zn, As and Sb, characteristic of a robust, high-grade, intermediate sulphidation epithermal system. Host rocks are folded Cretaceous-aged shales and sandstones of the Chicama formation that have been crosscut by a network of subvolcanic dykes and sills of andesite, dacite and monzonite.
Compilation by Focus of historic mine plans, and historical surface and underground sampling undertaken by the previous mine owners and other companies subsequent to the mine closure in 1982, has demonstrated that gold, silver and base metal mineralization continue along trend to the southeast beyond the area that was exploited 28 years ago. Many new veins and structures with consistently high grade gold and silver values are distributed over a mineralized corridor approximately 2 kilometres long and 250m wide.
Focus is targeting high-grade gold and silver mineralization in veins, mantos and faults that will be tested for multi-million ounce bulk mineable potential. Additional targets include structurally-controlled massive sulphide lenses, porphyry-related replacement bodies and disseminated Au-Cu mineralization.

The scientific and technical information in this release was prepared under the supervision of Mr. David Cass, Focus's President, who is a member of the Association of Professional Engineers and Geoscientists of British Columbia, and a "Qualified Person" in accordance with NI 43 101.
Samples were analyzed by ALS Chemex laboratories in Lima. Gold was assayed by Atomic Adsorption Spectrometry with fire assay gravimetric finish. Silver was determined by multi-acid digestion and ICP-AES, with fire assay gravimetric 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.
