DRILLING OUTLINES SIGNIFICANT EXTENSION OF COPPER ZONE AT MONS CUPRI
ASX Announcement ASX Code: VXR Released: 16 December 2010
Highlights potential for significant expansion of open pit resources at key Pilbara VMS[1] deposit
Key Points:
- RC drilling intersects 10m @ 1.15% Cu & 0.44% Zn 100 metres north of the Mons Cupri Cu-Zn deposit

-
Clear potential for continuous Cu-Zn mineralisation now defined over a strike length of 600 metres
-
Proposed open pit may be expanded to north
-
Further drilling planned in the New Year to underpin a new JORC resource estimate for Mons Cupri
Board
Venturex Resources Limited (ASX: VXR ) is pleased to report that drilling has outlined a significant extension to the Mons Cupri deposit, one of four key deposits which form part of its 100%owned Pilbara VMS[1] Project in Western Australia.
The new results highlight the potential for significant additions to the Company’s existing Mineral Resource inventory at the Pilbara VMS Project, which currently comprises Measured, Indicated and Inferred Resources of 7.6Mt grading 2.2% Cu Eq2 (determined in accordance with the JORC Code, 2004).
RC drilling designed to test for copper-zinc sulphide mineralisation in the corridor between the Mons Cupri deposit and Mons Cupri Northwest has returned results of up to 10 metres @ 1.15% Cu and 0.44% Zn from 38 metres.

This zone is interpreted to be flat-lying and contiguous with previous intersections below the Northwest pits, including 8 metres @ 4.15% Cu from 24 metres.
The results indicate that near-surface copper-zinc mineralisation may extend in this area over a total strike length of up to 600 metres .
Venturex plans to conduct further drilling in the Mons Cupri Northwest zone in the New Year to underpin a revised Mineral Resource estimate and re-optimisation of the open pits.

The positive results from Mons Cupri reinforce the excellent potential to further extend the known deposits and increase the resource inventory at the Pilbara VMS Project.
Venturex recently announced the results of a positive Scoping Study based on the development of a centralised processing facility at Whim Creek.
The reported Mineral Resources supports an initial mine life of nine years at a milling rate of 600,000 tonnes per annum, which would generate average annual metal production of 7,800 tonnes of copper, 13,900 tonnes of zinc and 4,200 tonnes of lead, with significant gold and silver credits.
Further Mineral Resource additions have potential to increase both the scale and longevity of the proposed operation.

Note: Rounding errors may occur.
Mineral Resources and Ore Reserves were determined in accordance with the JORC Code, 2004. Samples used in the estimations are from a combination of surveyed RC and diamond drill holes and geological confidence is high for each of the VMS deposits. Assays were determined in commercial laboratories by ICP and AAS methods. Bulk densities were determined by the water immersion technique. Wireframes for each deposit were interpreted using a combination of geological data and geostatistics. The block models were estimated by ordinary kriging using Vulcan 8.0 software. Classifications into Inferred, Indicated and Measured categories are based on a combination of weighted average distance from sample points, variography, drill density and geological confidence. Ore Reserves were estimated using a Net Smelter Return calculation on a cost, insurance and freight (CIF) basis and incorporating variable TC/RC terms and metal prices of: copper US$7715/t, zinc US$2205/t; lead US$2161/t; silver US$19.8/oz; and, gold US$1200/oz. The applied exchange rate is A$1.0=US$0.89. Reserve cut-off grades are: Mons Cupri open pit 0.62% Cu Eq; Whim Creek open pit 0.65% Cu Eq; Salt Creek open pit 0.72% Cu Eq; Evelyn open pit 0.76% Cu Eq; Salt Creek underground 1.96% Cu Eq; and Evelyn underground 1.4% Cu Eq. Cu Eq formula is: Cu Eq = Cu% + Zn% x 0.26 + Pb% x 0.24 + Ag(ppm) x .008 + Au(ppm) x 0.5.
