wowww FCV.V will explode!! newsssFocus Drills 10.5 g/t Au Eq. over 3.45m in First Hole at Chucara
Jan. 11, 2011 (PR Newswire) --
VANCOUVER - Focus Ventures Ltd. (TSX-V: FCV.V) is pleasedto report that it has received initial assay results from DDH-CHUC-001,the first hole to be drilled at its Chucara Au-Ag project. The hole isstill in progress at the time of writing.
Summary of drill results to date, hole DDH-CHUC-001:
| |
| From (m) | To (m) | Length (m) | True Width (m) | Au (g/t) | Ag (g/t) | Pb (%) | Zn (%) | Au Eq. (g/t*) |
| 127.2 | 127.8 | 0.6 | 0.55 | 5.0 | 345 | 5.8 | 11.0 | 22.7 |
| 168.8 | 169.5 | 0.7 | 0.64 | 1.8 | 19 | 0.3 | 0.6 | 2.7 |
| 216.1 | 219.55 | 3.45 | 3.14 | 3.5 | 203 | 2.1 | 2.2 | 10.5 |
*Au Eq. calculated grades based on $1300/oz Gold, $29/oz Silver,$1.10/lb Lead & $1.10 lb Zinc, and assumes 100% metallurgicalrecoveries.
DDH-CHUC-001 is positioned in the Northern Target Area and is beingdrilled to test the down dip extensions of the past producing Conzuso,Maria and Wenses veins below the historical workings. The intersectionsare coincident with the down dip projections of the convergence of theConsuzo and Maria veins, which are some 290m and 315m respectivelybelow the vein outcrops at surface. In the case of the Consuzo vein theintercept is 25m below the old workings and in the case of Mariaapproximately 170m below the old workings.
From 216.1m to 217m the hole cut massive sulphide vein mineralizationgrading 5.6 g/t Au, 512 g/t Ag (16.5 oz/t), 2.3% Pb, and 4.7% Zn (21g/t Au Eq.) and from 218.95m to 219.55m a second massive sulphide veingrading 10.0 g/t Au, 323 g/t Ag (10.4 oz/t), 7.6% Pb, and 4.3% Zn (24.1g/t Au equivalent) was intersected. The entire zone, including the lowgrade wall rock in-between the veins, assayed 3.53 g/t Au, 203 g/t Ag(6.53 oz/t), 2.1% Pb and 2.2% Zn (10.5 g/t Au Eq.) over a true width of3.14m.
Another significant intercept was drilled from 127.2m to 127.8m whichgraded 4.95 g/t Au, 345 g/t Ag (11.9 oz/t), 5.78% Pb and 11.0% Zn(22.7g/t Au Eq.) over a true width of 0.55m.
The mineralization is hosted by an interbedded sequence of siliceousgrey siltstone and black argillite intruded by a swarm of diorite anddacite sills. The massive sulphide veins cross cut the intrusions andthus far appear to have no spatial or genetic relationship to theintrusions.
Mark Slauenwhite P.Geo, Vice President Exploration of Focus, commented:"Even though it's early in the program these initial results from thefirst hole at Chucara demonstrate excellent vertical continuity of theveins which we now know extend below the old workings and average 300mdown dip below the surface. We've seen no indications that we are nearthe base of the mineralized system. We're also encouraged that thereappears to be no demonstrable change in the chemistry, metal zonationor grade of the mineralization suggesting that the system is stillstrong underneath the historical workings."

Project Background
Focus is evaluating a system of intermediate sulphidation-typeepithermal veins at Chucara for a high-grade gold and silver deposit.The 700 hectare property, located within a highly endowed mineral beltin north-central Peru, is 45km southeast of Barrick's Lagunas NorteMine and 18km east of the Comarsa Au-Ag Mine. The project covers themajority part of an historic Ag-Au (Pb-Zn) mine and the recentlydefined south-eastern extension of the mineralization.
The 3,000m drill program is designed to test the robust system of goldand silver-rich polymetallic veins for their high grade resourcepotential over the northwest-southeast trending corridor that is atleast 2 kilometres long. Specific targets include:
- down-dip and strike extensions of the past-producing Au-Ag (Pb-Zn) veins in the northern part of the concession and their deeper feeder zones, plus conceptual targets that were successfully outlined during a recent CSAMT survey.
- stacked, shallowly dipping quartz - semi-massive sulphide veins that were mapped over a 850m x 300m ridge in the southern part of the property, where a total of 91 samples gave average grades of 7.4 g/t Au and 439 g/t Ag (14.1 oz/t Ag) over widths averaging 0.6m.
- new high-grade veins and splays discovered by surface mapping and trenching that link the northern and southern areas.
Drill targets were defined by a comprehensive exploration programundertaken by Focus that included digital compilation of historicalwork, property-scale mapping, surface channel sampling, a geophysicalCSAMT survey and 3D modelling.
Sampling Quality Analysis and Quality Control
The drill program, including logging, drill core sampling and QA/QC isbeing supervised by Mark Slauenwhite P.Geo., Focus's Vice President ofExploration. Core was first split in half using a diamond core splitterand then logged, and each box photographed prior to sampling. Half-coresamples were bagged, security-sealed and transported by Focus personnelto ALS Chemex laboratories in Lima for analysis. Gold was assayed byAtomic Adsorption Spectrometry with fire assay gravimetric finish.Silver was determined by multi-acid digestion and ICP-AES, with fireassay gravimetric finish. ALS Chemex's quality control system complieswith International Standards ISO 9001:2000 and ISO 17025:2005.Analytical accuracy and precision are monitored by the analysis ofreagent blanks, reference material and replicate samples. Qualitycontrol is further assured by Focus's own QA/QC program which involvesthe insertion by Focus personnel of blind certified standards andblanks into the sample stream at regular intervals in order toindependently assess analytical precision and accuracy of each batch ofsamples as they are received from the laboratory. Finally,representative sample pulps are forwarded to an ISO-compliant thirdparty laboratory for additional quality control.
