VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 13, 2011) - Zincore Metals Inc. (News - Market indicators)(BVLAC:ZNC) ("Zincore" or the "Company") is pleased to announce it has received a positive Preliminary Economic Assessment ("PEA") for the development of its Accha Zinc Oxide District project ("AZOD") in southern Peru. At the AZOD, the Company is pursuing a district strategy with a single pyrometallurgical facility (Waelz kiln) to process zinc and lead oxide material from all AZOD deposits to produce a high grade zinc-lead oxide concentrate. The PEA considered two scenarios for the production of final products for sale. A Base Case investigated further processing of the concentrate by the Company to produce a special high grade zinc ingot and lead sulphate, by-product, while an alternate scenario, the Fume Case, considered selling the zinc-lead oxide concentrate to a third-party refinery.

In addition to AMECs recommendation for a pre-feasibility study on the AZOD Project, AMEC constructed a mineral resource model for the Yanque Deposit portion of AZOD for use in the PEA. The new Mineral Resource estimate, which replaces the previous estimate announced by Zincore in 2008, totals 12.5 Mt of Inferred Mineral Resources with an average grade of 3.5% Zn and 3.7% Pb within a Mineral Resource pit shell constructed considering a zinc price of US$ 1.08/lb Zn and US$ 1.00/lb Pb. Mineral Resources were estimated by Chris Wright, P.Geo. of AMEC, a Qualified Person as defined under NI 43-101, and have an effective date of 31 May, 2011.
The PEA is preliminary in nature, and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. Mineral resources are not mineral reserves as they do not have demonstrated economic viability.
The final PEA technical report will be filed on SEDAR within 45 days. To view a fact sheet summary of the PEA, please click here: http://www.zincoremetals.com/en/common/reports.php
Zincore President and CEO, Jorge Benavides, commented "The robust economics detailed in this PEA report are fantastic news for our Company. Not only does the report recommend that we proceed to Pre-Feasibility based on the economic analysis of two initial scenarios, it also suggests a number of areas where we may be able to further improve on the report findings. It also includes a sensitivity analysis which demonstrates how the project economics could dramatically improve with increases in the underlying prices of zinc and lead. Given that we continue to believe there is a coming supply shortage of these two commodities by the 2015 date we would expect to be in production, the sensitivity analysis is particularly important. The bottom line is that markets may be depressed now, but it takes many years to bring a new zinc operation into production and we don't see how enough new zinc production can be brought on-line in time to meet global demands a few years out."

Opportunities for Investigation to Further Improve AZOD Project Economics
The Company is considering undertaking further evaluations of several aspects of the project that may extend the life and/or profitability of the project that include:
- Expanding the resource base and confidence levels on both the Accha and Yanque deposits
- Conducting further exploration and drilling on other known zinc/lead oxide deposits within the AZOD, which may lead to the development of further mines to supply ore to the central processing facility
- Further detailed pyrometallurgical and hydrometallurgical test work to optimize the economics of the planned metallurgical process route
- Further studying and evaluating improvement of mine design and logistics relating to the transport of ore and oxide fume
- Further evaluating the planned refinery at the port of Mattarani and considering the option of finding a strategic partner for the development of the refinery
- ZNC believes the refinery will be strategic to the sourcing of other oxide concentrate feed from third parties.
