Duran Ventures Commences Metallurgical Testing Program of Aguila Copper/Moly Property, Ancash District, Peru

TORONTO, ONTARIO--(Marketwire - Sept. 28, 2011) - Duran Ventures Inc. (TSX VENTURE:DRV) ("Duran" or the "Company") has engaged G&T Metallurgical Services Ltd. ("G&T") of Kamloops, BC to begin a series of laboratory tests to determine the metallurgical character of the potential ore types at the Company's flagship Aguila Porphyry Copper ("Cu") – Molybdenum ("Mo") Property located in the Department of Ancash in north-central Peru. These programs are designed to determine prospective metal recoveries and applicability of conventional grind/flotation processes that can be applied for future economics for the project. Representative samples of the Aguila mineralization will be prepared from drill core assay sample rejects by Duran's geologists and shipped directly to G&T for the purposes of this program.

Duran is nearing completion of this year's, 15,000 metre, 26 hole drill program. In total, from 2007 to the end of the current year's program, there will be 43 drill holes completed at the Aguila project representing approximately 23,000 metres of core drilled. Results for drill holes AGD-18 to AGD-33 were reported by the Company in a series of news releases spanning June 6, 2011 to September 15, 2011.The remaining results are pending. All drill core has been split under the supervision of the Company's geologists and assayed at ALS Chemex Labs. A Quality Assurance and Quality Control Program (QA/QC) has been undertaken by the Company's geological team under the direction of the Company's supervising P.Geo and President, Cary Pothorin. The data for this program and the previous 17 drill holes (8,000 metres) will be provided to SRK Consultants of Toronto, Canada who have been retained by the Company to prepare a preliminary NI 43-101 compliant mineral resource estimate for the Aguila project. SRK is expected to complete their work and provide the Company with the resource estimate early in the New Year.

The project is located approximately 80 kms north of the Antamina Silver/Lead/Zinc/Copper Mine (owned by Xstrata, BHP and Mitsubishi), and less than 40 kms south of the Magistral Cu/Mo deposit currently being developed by the Peruvian company, Milpo. Peñoles of Mexico is currently drilling copper mineralization on their Racaycocha project, 2 kms south of the main Aguila area. Furthermore, Duran recently acquired a 100% interest in the Mamaniña Cu/Mo/Au property, 14 kms south of Aguila. Mamaniña hosts porphyry style copper mineralization along this trend of porphyry copper mineralization that Duran believes is part of a significant and new porphyry copper district.

Many of the drill holes completed at Aguila have been collared in copper-molybdenum mineralization and the Company anticipates that it will need to continue stepping back from its current grid of drill holes to ultimately determine the limits of the copper-molybdenum mineralization. The SRK initial resource estimate and statistical modeling will assist the Company in determining its continuing plan to expand and advance the Aguila project to a preliminary economic assessment (PEA).

Duran's geologists have determined that the copper mineralization intersected in drilling is predominantly in the form of chalcopyrite which indicates hypogene style porphyry copper mineralization. Molybdenite is the principal molybdenum mineral noted by the Company's geologists. Multi-element ICP analysis on sectioned drill core throughout the program has indicated low or insignificant levels of deleterious metals which suggest low potential for such metals to contaminate prospective flotation concentrate products from the project.

Preliminary Metallurgical Assessment Program

To begin their work at Aguila, G&T will be provided by Duran with 2 drill core sample composites:

  1. A statistically higher grade copper composite sample
  2. A statistically lower grade copper composite sample.

Each of these composite samples will include mineralized porphyritic diorites and host sedimentary rocks. The molybdenum grade has been noted to be fairly uniform throughout the Main Aguila mineralization.

G&T will perform grindability testing on the 2 composite samples that will include:

  • Standard Bond ball mill work index tests
  • Standard Bond rod mill work index tests

Additionally, G&T will perform SMC tests on uncrushed drill core samples of the porphyritic diorite and sedimentary host rocks provided by the Company.

G&T will analyze each composite sample for sulphide mineral content and fragmentation characteristics on differing particle size ranges. They will then proceed with preliminary flotation test work of the composite samples:

  • 5 rougher tests
  • 5 open circuit cleaner tests
  • 1 locked cycle test

Conventional common reagent schemes and test flowsheets will be applied to treat this style porphyry copper mineralization. The concentrate produced from the locked cycle test for each composite sample will also be assayed for common deleterious elements and payable minor elements.

This program is planned to take approximately 2 months from receipt of samples and Duran expects to have these initial metallurgical results available early in 2012 coincident with the SRK resource estimate.
