Afton-Ajax Copper-Gold Project, Canada

Located near Kamloops in British Columbia, Canada, the Afton-Ajax copper-gold project is being developed by New Gold and Abacus Mining and Exploration. The development area, Afton-Ajax Cu-Au District, is operated by Abacus. The mine contains approximately 80% surface resources and 20% underground resources. The open-pit resources are owned by Abacus, which also owns 60% of the underground resources.

Teck Cominco was the operator of Afton-Ajax until it sold the rights to Abacus in November 2005. As part of the deal, Abacus purchased a mill and tailings pond at Afton. The related permits, access rights for the tailings, water and some surface rights were also acquired.

"The mine contains approximately 80% surface resources and 20% underground resources."

In order to accelerate the development of the mine, Abacus entered into an investment agreement with KGHM Miedz in May 2010 to form a joint venture (JV) that would explore Afton-Ajax.

Under the agreement, KGHM will own 51% of the JV by paying $37m in cash to Abacus. The terms of the agreement allow KGHM to acquire a further 29% in the JV after completing a bankable feasibility study.

TD Securities was KGHM's financial advisor for the transaction, while CIBC World Markets was the financial advisor to Abacus.

Geology and reserves

Afton-Ajax contains porphyry deposits of alkalic copper-gold. Abacus and New Gold completed Phase I drilling at the site by 2008. Analysis of the drilled samples was done by Eco Tech Laboratory.

Abacus carried out a series of diamond drilling programmes at the site during 2005-08. It completed more than 520,000ft of drilling by 2008. AMEC Americas was contracted in June 2008 to provide engineering services for the project. It also prepared a mineral resource model to estimate the reserves at the deposit.

"Approximately 80% of the estimated resources are in the area owned by Abacus."

As of June 2009, the measured and indicated resources at the mine were expected to be 442mt grading 0.30% Cu and 0.19g/t Au. The inferred resources were approximately 80.6mt graded at 0.22% Cu and 0.16g/t Au. These estimates were based on 0.13% copper equivalent cut-off.

Approximately 80% of the estimated resources are in the area owned by Abacus. The remaining 20% are in the area shared between Abacus and New Gold.

Production

The technical feasibility in the preliminary economic assessment report was established assuming annual copper production of approximately 50,000t and gold production of 100,000oz.

Open-pit mining

The open-pit mine plan assumes an average strip ratio of 1.7:1. The open-pit will contain 12m benches. The pit slopes will be adjusted according to the geology. Electric drills will be used to drill the ore and waste. They will be able to drill blastholes of 311mm in diameter. Haul trucks will transport the blasted material from the site to a gyratory primary crusher. Electric rope shovels and front-end loaders will be used to load the material into the haul trucks.

New Gold owns a portion of land and a water pipeline in the Afton area, which it acquired from Teck Cominco in 2007. The land lies between the mill and tailings acquired by Abacus. Teck Cominco was using the pipeline to supply water to the open-pit mine at Afton. In March 2008, New Gold agreed to share the pipeline with Abacus to supply water to Afton-Ajax.

Ore processing

"Abacus expects that the mining operation will have the potential to process 60,000t of ore a day."

The ore crushed at the gyratory crusher will be delivered to a copper concentrator that will include a 40ftx25ft SAG mill and two 24ftx42ft ball mills. The concentrator will recover copper and gold concentrates from the feedstock using a conventional flotation circuit. The recovery is followed by filtration before the concentrate is shipped out.

Abacus expects that the mining operation will have the potential to process 60,000t of ore a day.

Costs

Wardrop Engineering completed the technical feasibility of the mine development in July 2009 and estimated that the project would cost $535m. The mine life was assumed to be 23 years starting from 2013. The feasibility was based on the average mining costs of $1.17 per pound of Cu and $700 per ounce of Au.

Environment

The environmental assessment made by Wardrop concluded that the project would not cause any significant harm to the flora and fauna in the surroundings of the project site.

Potosi Silver Mine, Australia

The Potosi underground mine is located approximately 2km to the north of the existing North Mine and is parallel to the main Broken Hill Line of Lode, in New South Wales, Australia. It includes two mining zones, known as Potosi North and Potosi Extended.

Owned and operated by Perilya, drilling of the Potosi Mine commenced in March 2007 but was kept under care and maintenance since September 2008 due to falling metal prices. Exploration studies continued through 2009 and confirmed the existence of minerals between the Potosi North and Potosi Extended zones.

The development was approved by the Broken Hill City Council in March 2010. The project was re-approved by the Perilya Board in February 2011, four years after the initial plans.

Development of the Potosi mine

"Potosi underground mine is located approximately 2km to the north of the existing North Mine in New South Wales."

Development work at Potosi began in 2011 and the production is expected to commence in late 2012. The project will mine at a rate of 450-500mt a year using the existing infrastructure and mining labour force of the Broken Hill Southern Operations.

The development cost of the Potosi silver mine is estimated at A$57.8m. Perilya will be funding the project from its existing cash reserves.

The Silver Peak deposit located adjacent to the mine is also being developed, along with the Potosi mine, as a combined project.

The development of Potosi / Silver Peak mine is expected to increase the production levels of the existing Broken Hill Mine by 30,000t in its first full production year and subsequently ramp-up to 45,000t.

Geology of Perilya's Potosi mine

The Potosi resource comprises narrow lenses present continuously from near the base of the pit to north of the Flying Doctor deposit located 10km north of the Broken Hill Southern Operations. The mineralised zone is 3km in strike length.

Potosi North and Potosi Extended represent 50% of the targeted mineralised zone along the strike.

Reserves at the New South Wales-based Australian mine

The Potosi Mine has inferred resources of 1.6 million tons (mt) at 14.1% of zinc and 3.4% of lead and 46 grams per tonne of silver (g/t). The Silver Peak mine has inferred resources of 390,000mt with 4.9% zinc, 9% lead and 77g/t silver.

Mining production methods to be used at the Potosi underground mine

Potosi mine was originally mined by Pasminco between 1996 and 2000 and was acquired as part of the Broken Hill prospect by Perilya in 2002. It was a 95m open-pit mine with an yield of 625,000t at 7.8% zinc and 1.6% lead.

"The development cost of the Potosi silver mine is estimated at A$57.8m. Perilya will be funding the project."

Potosi underground mine has a 1,400m decline developed from the previous open-pit mine. Its face is at 140m from the surface. A second decline will be developed adjacent to the Silver Peak mine and will be linked to the existing decline access.

Mining at Potosi will be undertaken through the modified Avoca method, wherein the ore is extracted in bottom-up sequence. A single crown pillar method will help achieve early ore production.

Stoping operations at the underground mine will be performed from a previously mined and now backfilled stope.

The current stope's width will be 3-15m and height 25m from the floor length. Waste rock will be used to backfill the stopes.

The ore will be transported in an underground truck to the surface, where it will be crushed in a portable crushing unit.

Potosi mine ore processing

The ore extracted at the Potosi mine will be processed in the Broken Hill Southern Operations concentrator. An access road will be laid to the Barrier Highway and the North Mine to truck the ore to the concentrator.

The capacity of the Southern Operations concentrator is 2.5mt. It is currently operating on a ten-day on / four-day off schedule and has idle capacity.

Processing of the Potosi and Silver Peak's crushed ore will bring the concentrator to full capacity and hence minimise the operating costs.

Germany gold ore beneficiation plant

At the beginning of the 2011, one report shows that there is one huge gold ore under the ground (it is about 1000meters) in the east of Germany. Exploration estimates that 15 tons gold and 3 million tons copper are reserved.

It will be the largest Germany gold ore deposit. Meanwhile, this deposit include great many silver, Zinc and Lead ore. Preliminary estimate, this deposit value is about 8~9 billions Euro. One new Germany gold ore beneficiation plant will be built in the neat future in this area, and it will bring a great many job opportunities and do great contribution to Germany industry development.

Germany Gold Ore Processing Equipments

Usually the Germany gold ore processing mining plants are quite similar with each other. No matter which country they are built, they do be the same, like the following gold ore crusher and gold ore concentrating machinery.

Because the gold ore are under ground, so they must be transported out from the gold well. And the raw size is not very big. They can be crushed by the jaw crusher directly. When the raw ore are transported to the crushing sites, three processing processes are necessary: the primary crushing process that crush them to small lumps; the secondary crushing process that crush them to small chips; the screening process that separate the qualified ones from the particles.

Jaw crushers are usually used as the primary crusher; the movable jaw and the fix plate press the raw ore to small lumps and discharged from the jaw crusher, these lumps are transported to the cone crusher. In the cone crusher, the ore will be pressed between the mantle and the bowl liner. By using the vibrating screen, producers can adjust the wire mesh size according to different requirements. At last, the classified chips will be conveyed to the belt conveyors by the belt conveyors.

Germany gold ore powder milling machineries

Germany gold ore powder milling machineries are often ball mills. Double usually offer customers ball mill, hammer mill and MCF series coarse powder mill and so on for grinding gold ore. With these mills, the crushed particles are ground to small powder for gold ore concentrating process. The discharge size depends on the design of the whole gold ore beneficiation plant.
Discharged from the ball mill, various concentrating method can be used, such as Gold gravity-separation, flotation, etc. Processing equipments are matched with the design. Passing through series of machineries, high grade gold can be gotten.

Finally we got an agreement of one design and they placed an order after visiting Double Company and Double factory. In this Chrome ore crushing plant, one unit vibrating feeder, one unit jaw crusher and two units cone crushers and two units vibrating screen are used.

Chrome ore processing equipment

The whole crushing process begins from dumping the raw ore to steel hopper above the vibrating feeder, which ensure steady feeding process. Double vibrating feeder structure is very simple and we strengthen the wear parts, increasing the service life greatly. To the jaw crusher, we adopt heavy movable jaw and optimized connect methods, in this way, the hard mining ores can be crushed easily.

Obviously, jaw crushers are just primary crushers, they can crush big lumps to small lumps, but the products output size is still bigger than customers’ requirements. So when material discharged from the bottom of the jaw crusher, they are transported to one transfer station by belt conveyors. Under the transfer station, there are two units electric vibrating feeders, they feed the crushed lumps to belt conveyor steadily.

Then the lumps will be fed to the cone crusher. Double has two series cone crusher for sale in South Africa, one is HP series hydraulic cone crusher and another one is S series cone crusher. Here considering the budget, we suggest customer using two set S series cone crushers. By using this type cone crusher, customers can crusher mining ore aggregates to small particles easily.

For example, mining ore lumps can be crushed to 0~5mm, 5~10mm, 10~20mm or 0~1/8”, 1/8”~1/4”, 1/4”~1/2”, 1/2”~3/4” and 3/4”~1”. These size ranges well satisfy the world’s customers’ commonly requirements. Particles outputted from cone crushers are mixed with each other, to separate the different sizes particles, Double vibrating screens are necessary. The wire meshes are changeable, so producers just need to change the wire mesh if they need produce different size products. Finally, the qualified ones are conveyed to the store pile sites and oversize ones are transported to the cone crushers for crushing again.
