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.

Coal processing equipments in South Africa

South Africa is not only rich in metal mining, but also rich in the nonmetal mining resources. For example, the coal reserve is the seventh of the world. Now South Africa is one the chief coal production countries, it is the fourth largest exporting country of coal and it is also the leader production country of liquid fuel made of coal.

Coal Processing Equipments

South Africa coal processing equipments offered by SBM are mainly jaw crusher, impact crusher, hammer crusher, ball mill and LM series grinding mills and feeder, screens and belt conveyors, etc.

Many producers produce coal aggregates, the coal crushing plants are able to satisfy their requirements. Many producers produce coal powders or process coal ash; in this case, the coal grinding machineries are very important.

Coal crusher plants

The commonly process of coal crusher plants in South Africa are similar with each other. Jaw crushers crush big coal lumps to small ones when they dig out from well or from deposits. It is really a easy work for Double jaw crusher. Actually, Double jaw crushers can be used to crush numerous mining ores and different stones, such as granite, marble, basalt, gravels, limestone, gypsum, clay, manganese ore, chrome ore, iron ore, gold ore, copper ore and zinc ore and so on.

As to the impact crushers, if the raw coal size is not very big, they can crush the lumps to small particles directly; if the raw coal size is big, impact crushers are used behind the jaw crushers. Though the application of impact crushers is wide, but impact crushers should used in crushing soft materials. If the coal deposit is small and producers just want to build one small coal production line in South Africa, Double hammer crushers are really good choices. Also, the output size of hammer crusher is quite small and adjustable, no other better machines are better than them in this function.

Coal grinding process

In the coal grinding process, ball mill and LM series grinding mills are widely used. It is well-known that many factors must be cared when producers grind coal powders, for example the inflammability. Double LM series grinding mill and ball mill well solve these problems.
