Zincore Completes Positive Metallurgical Testwork Program on Accha Deposit

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 25, 2007) - Zincore Metals Inc. (TSX:ZNC) ("Zincore" or "the Company") has successfully completed metallurgical test work on ore from its Accha property and has concluded that the ore can be substantially upgraded. A mineral resource estimate is being prepared on the deposit and the Company plans to complete an accelerated development study on Accha. Accha is a near-surface zinc oxide deposit that forms part of Zincore's 100% owned Accha-Yanque Project in southern Peru.

As a component of Zincore's pre-feasibility activities on the Project, Green Team International ("GTI") has been supervising completion of metallurgical test work on Accha ore. The work has focused on concentration and limestone removal prior to the ore being processed through a leach and solvent extraction electro-winning circuit ("SXEW") to produce zinc metal. The Accha zinc mineralization is hosted in limestone, making calcium removal prior to leaching important to the project's viability.

Samples grading 7.6% zinc were concentrated to between 25% and 30% zinc through dense media separation ("DMS") and flotation with greater than 90% of the acid consuming limestone gangue material being rejected. Zinc recovery from ore through to zinc oxide concentrate was approximately 75%. Samples were composited from four metallurgical drill holes totaling 1,000 kilograms of ore. Further optimization of concentrate grade and recovery through lock-cycle testing is planned as a second phase of test work which would be conducted following a positive pre-feasibility study.

Timo Jauristo, Zincore's President and CEO commented, "This work takes Zincore significantly forward in the development of our Accha deposit. By confirming that low acid-consuming, high-grade zinc oxide concentrates can be produced from the Accha ore, acid consumption should not be an impediment to applying conventional leach and SXEW to the Accha deposit. In addition, the concentrate zinc grade is sufficiently high that we believe an opportunity exists to accelerate the development of Accha through third party offtake of the concentrate. We will complete a study of this option in parallel with the evaluation of our integrated Accha-Yanque SXEW Project."

Metallurgical test work was completed at Mintek Laboratories in Johannesburg, South Africa on composite samples from four holes drilled in the Accha deposit. GTI supervised a number of DMS, flotation and other bench-scale tests to examine the separation of the zinc minerals from the acid-consuming gangue in the Accha ore. Based on that work, a preliminary design of the Accha concentrator circuit was developed comprised of crushing and screening followed by two-stage DMS of the oversize and milling followed by amine flotation of the DMS sinks and undersize. All zinc minerals in concentrate have shown excellent leaching response using conventional acid leach (greater than 97% zinc recovery from concentrate).

The majority of zinc mineralization at Accha occurs as smithsonite, a zinc carbonate and hemimorphite, a zinc silicate. However, mineralogical analysis identified that a portion of the Accha zinc mineralization is sauconite, a zinc clay. Zinc clays comprised approximately 10% of the zinc in the metallurgical sample. Sauconite is low density and, therefore, reports with the gangue material in the DMS stage which impacts upon recovery. Test work has shown that sauconite can be recovered by utilizing a second DMS step at a lower specific gravity in order to separate the sauconite from the gangue material. Zincore is mapping the quantity and location of zinc clays in the deposit in advance of assessing whether two-stage DMS is the preferred economic approach. If two-stage DMS is utilized zinc recovery to concentrate would increase to approximately 80%.

Zincore has completed the first phase 62-hole drill program on the Accha deposit and has finalized associated geological work. This information has been forwarded to Pincock, Allen & Holt ("PAH") for completion of mineral resource estimation on the deposit in advance of their mine planning and mine design work. Upon completion, Zincore anticipates commencing a pre-feasibility study on the Accha deposit based on third party offtake of zinc oxide concentrates. Zincore has engaged SNC Lavalin Chile to complete the pre-feasibility study with process design provided by GTI.

Exploration drilling at the Yanque deposit is ongoing with additional assay results expected shortly. Two metallurgical drill holes have been completed and the entire core has been shipped to South Africa where GTI has commenced test work on the Yanque ore at the Mintek laboratory.

About Zincore

Zincore's strategy is to become a leading, low-cost zinc producer with the immediate objective of advancing its 100% owned Accha-Yanque property toward a development decision through a disciplined process of exploration, drilling and resource definition, and technical studies. Zincore holds a portfolio of other zinc exploration properties in southern Peru and intends to pursue additional zinc opportunities elsewhere in Latin America.

About the Accha-Yanque Project

The Accha-Yanque property consists of 56 concessions over a 30-kilometre distance in southern Peru. At the north end of the property is the Accha deposit and at the south end is the Yanque deposit. A number of zinc prospects with limited prior exploration occur between these two deposits. Zincore has completed 62 holes totaling over 16,000 metres of diamond drilling at Accha and is currently completing an infill and exploration drilling program at Yanque. Pre-feasibility level engineering work is progressing on both deposits.
