Publication of Expert Independent Report

Frontier Mining (AIM:FML), the AIM listed exploration, development and production company focused on Kazakhstan, announces the publication of an Independent Expert Report, by Wardell Armstrong International, entitled "Review and Preliminary Valuation of Baitimir Project Located within the Naimanjal License Territory NE Kazakhstan, dated 16 July 2013."

Wardell Armstrong International (WAI) is an independent engineering and environmental Consultancy, which has provided the mineral industry with specialised geological, mining, and processing expertise since 1987. WAI was commissioned by Frontier to prepare a scoping report to include a preliminary financial evaluation, based on data provided by Frontier up to 25 December 2012, of the Baitimir project. The project is located within the Naimanjal license, and is comprised of the Baitimir, Yubileiny and Beschoku copper deposits.

This report documents the geological block preliminary modelling and mineral resource as at October 2012, and is a non JORC (2004) compliant desktop report.

The results of the financial modelling show that, when applying various discount rates between 8% and 20% the model produces Post Tax Net Present Values of US$17 million and US$67 million respectively based on income from the recovery of copper, silver, gold, magnetite and molybdenum. The internal rate of return (IRR) for the Baitemir and Beschoku projects are approximately 40% with a payback period outlined in the report of 2.73 years. Wardell Armstrong estimates that the cash operating costs over the life of mine are approximately US$10.01 per ton of oxide ore processed and US$19.79 per ton of sulphide ore.

DCF Model Results (Before Funding and Debt Service):

The review and preliminary valuation support Frontier Mining's view that Baitimir is an attractive project with robust economics. Frontier will keep all options open as to the optimal development strategy for the Baitimir whether that be from its own resources, through joint venture or through the sale of the project to a third party.
