Zincore to Enhance Accha Zinc Oxide District Project Mine Plan With More Data From Yanque Definition Drilling Program
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 11/23/11 -- Zincore Metals Inc. (TSX: ZNC)(BVLAC: ZNC) ('Zincore' or the 'Company') announces the results from the final 38 holes of its 2011 definition drilling program at the Yanque deposit located at the Accha Zinc Oxide District project in southern Peru. Highlights from these holes include: 18.53% Zn Eq(i) over 9.0 metres in hole YA-126, 13.54% Zn Eq(i) over 11.0 metres in hole YA-94, 13.04% Zn Eq(i) over 10.5 metres in hole YA-97, 12.55% Zn Eq(i) over 19 metres in hole YA-96, 12.94% Zn Eq(i) over 6.0 metres in hole YA-105, 12.63% Zn Eq(i) over 7.0 metres in hole YA-104 and 11.18% Zn Eq(i) over 7.0 metres in hole YA-128.
(i)Figures are expressed as zinc equivalents using a ratio of 1:1 lead to zinc and do not include any potential silver credits. Metallurgical recoveries and net refinery returns are assumed to be 100%.
For a complete list of results, please see Table 1 below.
Zincore President and CEO, Jorge Benavides, commented 'We are very pleased with the results from this latest stage of definition drilling at the Yanque deposit. The information we have gained will help us further improve the mine plan contained in our recently released Preliminary Economic Assessment ('PEA'). With the solid baseline economics already detailed in the PEA, we can now concentrate on further improving the attractiveness of the Accha Zinc Oxide District project, including working to increase the known resources at both the Yanque and Accha deposits and other District targets.'
The Company has now completed the 2011 portion of the definition drilling campaign for the Yanque deposit. This program was comprised of 78 holes and totaled 9,827 metres. Total drilling at Yanque since inception now stands at 128 holes comprising 16,354 metres. In 2010, the Company completed a similar definition drilling program at the Accha deposit, located 30 kilometres to the north.
It is expected that this latest drilling information will help the Company better define the high grade portions of the Yanque deposit and to generate a new geologic model to further optimize the PEA mine plan where a single facility could process zinc and lead ores from Yanque and Accha, as well as the other 100% owned District prospects yet to be tested. The ability to selectively mine the higher grades of mineralization in the early years of a mine plan could significantly enhance the economics of the Accha Zinc Oxide District project.
It is not expected that these latest drill results will have a material impact on the resource estimate included in the Company's PEA released November 16, 2011. The Company expects that if necessary, it will update the PEA resource estimate when it releases a Pre-Feasibility report.

Quality Control
Zincore has implemented a quality control program to ensure best practice in litho geochemical sampling and analysis of rock chips, trench, tunnel and drill core samples.
All drill core samples (approximately one metre, half-core composites) are shipped in security sealed bags via a private trucking company directly to the Acme Laboratories facility in Lima. All samples for the resource drill program are analyzed using two techniques: zinc and lead grades are determined by a four acid digestion and AAS finish, and if the results exceed 10% they are re-assayed by volumetric methods. In addition, all samples are assayed by ICP-ES for 36 elements including silver and if values exceed 200 ppm of silver, samples are re-assayed by an ore grade method with AAS finish.
The Company submits its own standards and blanks as a measure of the accuracy of the analysis. All pulps and coarse rejects are recovered and stored. Prior to a new resource estimate, 10% of all samples used in the resource calculation will be re-assayed at a second laboratory using the same analytical techniques described above. This includes re-assaying of pulps from the coarse rejects.
