Baitemir Assay Results (March, 2012) First results from the Baitemir drill programme have met

expectations and are consistent with previous reports; thecopper project continues to demonstrate significant potenti

Drilling and data accumulation will continue ahead of the,

scheduled for the fourth quarter 2012.

Benkala Production Imminent (April, 2012) The Commission certifying start-up is on-site and miningoperations are ongoing on a daily basis. Copper Cathodeproduction is fast approaching, a key milestone for Frontie

Construction and operations teams are working at full capto ensure that commencement of production remains on tasc e u e or une s year.

Benkala Mining Targets Achieved (May, 2012) Mining operations have consistently achieved the daily tar

of 8,000 tonnes of ore, as planned for normal conditions.

Frontier remains on track to achieve Copper production ofbetween 3,500 and 5,000 tonnes in 2012, with the plantoperating at its optimal capacity of 7,000tpa.

Benkala Plant Technolog

The fundamental recovery process is the tried, tested andtrusted Heap Leach; taking oxidized copper ore and

converting it to metallic copper cathode sheets.The cathode sheets that the Benkala SX-EW plant willproduce are 99.99% pure, the highest value and purityattainable reatl reducin the shi in and trans ortcosts when compared to other copper concentrateprocesses which require further processing.

This product is in high demand and can be fed straight intoa number of downstream users processes, in particularhigh speed drawing of thin copper wire - used for high-techelectronics applications.

Benkala presented our team at Calder with an opportunityto utilise the very latest SX-EW technology and incorporate

best of breedequipment from around the world to createa state-of-the-art facility, the first if its kind in the region.

France has provided the Cathode Plates and StrippingMachine, using the latest welding techniques to ensure thatthe lowest possible electrical resistance to current isoffered by the join between the stainless steel cathode

KazCopper were key to our understanding Kazakh

procurement requirements, acid storage regulations andcold weather engineering. I enjoyed working with them, notonly did they listen to our recommendations, but alsohelped us develop our approach where they could seeroom for improvement, particularly with regard to issues

.

The project has been largely dependent on the expertise ofthe local Kazakh workforce, who have achieved in a veryshort space of time what other companies haveunsuccessfully attempted for decades. The constructionteams work long hours, often in arduous conditions, yetalways make good progress.

The Glass Reinforced Plastic Tanks from Chile use vinylester resins and filament wound glass fibre reinforcement,

developed for worlds largest SX-EW plant.The main Power Rectiformer, converting AC current to DCcurrent to electrowinn the copper, is an efficient 12 pulsesolid state rectification unit develo ed in the US. TheElectrolyte Filter uses a triple media of silica, anthraciteand garnet to polish the copper electrolyte to ensure a highpurity feed to the electrowinning cells, preventing unwantedparticles contaminating the cathode.

Further to sourcing specialist equipment internationally;Calder has worked with KazCopper to ensure thatsignificant general engineering components were suppliedby local Kazak companies, such as the Agglomerator,Conve ors and the lar e steel tanks..

The engineers we dealt with are hardworking and

knowledgeable, products of the high standards proliferatedby the excellent Kazakh education system.

I was truly surprised at how modern and advancedKazakhstan really is, my preconceptions based on moviestereotypes were far from the truth. The people are verys m ar n many ways o us ra ans; rec an s ra g -talking, they are a small vibrant multicultural populationliving in a big country, enduring harsh environments,surviving governance by foreign power and emerging as astrong economic force with a commitment to developmentand modern technology.
