"We are very pleased that Mr. Hewgill is joining Antares Minerals and view his decision as a strong endorsement for the potential to reveal significant additional value at our Haquira Project. The Haquira project is emerging as one of the largest and most attractive undeveloped copper deposits held 100% by a junior exploration company. Mr. Hewgill brings additional skill sets to Antares including the ability to provide discounted cash flow analysis for various financing, development and monetization scenarios. He will be able to make immediate contributions as we advance Haquira through the pre-feasibility process and develop strategies to maximize the value of Antares for our shareholders."

About the Haquira Copper Project, Peru

The Haquira project is located in southern Peru and offers excellent potential for the development of a large copper mine with production from both near-surface secondary copper mineralization amenable to SX-EW leaching and from a larger, underlying body of higher grade primary porphyry copper-molybdenum mineralization to be processed by a conventional mill/concentrator operation. Haquira is located contiguous to, and immediately south of, Xstrata Copper\'s Las Bambas Cu-Au project and consists of two blocks of property acquired or optioned under separate agreements as well as additional concessions acquired by Antares for a total of 20,635 hectares of area. Antares has recently announced an update Resource Estimate (February 26, 2010) and integrated Preliminary Economic Assessment (PEA - July 22, 2010) for the project. Highlights from the PEA include:

* After-tax NPV of US$ 1.07 billion for base case with US$2.25/lb Cu and 8% discount rate

* After-tax IRR of 16.4% for base case with US$2.25/lb Cu – payback of capital in 4.8 yrs

* Process rate of 130,000 t/day (30,000 t/day SX-EW leach and 100,000 t/day mill/flotation)

* Twenty year mine life

* Initial capital expenditure of US$ 2.06 billion (including working capital and a contingency of 20%)

* Average production of 425 million lbs Cu/yr (193,000 t Cu/yr) for life of mine

* Total production of 8.3 billion lbs Cu, 97 million lbs Mo, 522,000 oz Au, and 24.3 million oz Ag

* Cash cost of US$ 0.89 for first ten years and US$ 1.04 for life of mine (C1, includes transport and TCRC charges and is net of by-product credits)

* Strongly leveraged to price of Cu (based on price range of $2.00-3.00/lb)
o After-tax IRR ranges from 12.4% to 26.3%
o After-tax NPV(8%) ranges from $516 million to $2,730 million

About Antares

Antares is a successful mineral exploration company with highly experienced technical and management teams. The Company is focused on precious- and base-metal exploration properties in Latin America that can be quickly and cost-effectively advanced to the discovery and production stage. In addition to the Haquira Project in Peru, Antares is also currently exploring the Rio Grande (Cu-Au porphyry) project in Salta Province of NW Argentina in a 50/50 option/joint-venture basis with Pachamama Resources Ltd., a spin-off from Mansfield Minerals Inc.


(*) CuEQ = Copper Equivalent is calculated for intervals dominated by primary mineralization using US$1.50/lb Cu, US$500/oz Au, US$10/oz Ag and US$10.00/lb Mo and is not adjusted for metallurgical recoveries as these remain uncertain. Metallurgical recoveries and net smelter returns are assumed to be 100%. The formula used is as follows: CuEQ = Cu% + (Au g/t x 0.4862) + (Mo% x 10.00/1.50) + (Ag g/t x 0.0077). Copper Equivalent contributions are only applied to primary sulphide mineralization.

Mineral resources do not have demonstrated economic viability and future in-fill drilling and scoping, pre-feasibility and feasibility studies will determine what percentage of the inferred resource can be placed into the mineable category.
