Process Of Mining Gold Fields In Cerro Corona Mine

The Cerro Corona Mine in the highest part of the western Cordillera of the Andes Mountains in northern Peru, two kilometers north-west of the village of Hualgayoc in the Department of Cajamarca

Cerro Corona mine cover an area of 4,379.3 hectares, while the surface rights cover 1,244 hectares. The Cerro Corona Mine is mining methods open-pit situated in the highest part of the western Cordillera of the Andes Mountains in northern Peru, two kilometers north-west of the village of Hualgayoc in the Department of Cajamarca. And this gold mine owned  by Gold Fields La Cima S.A. (GFLC) a wholly owned subsidiary of Gold Fields Limited (GFL) which holds 99.53% of the economic interest, from the original 80% to 98.6% in 2012 and in 2013 to 99.53%.

Earlier in the year 2003, Gold Fields, through a subsidiary, signed a definitive agreement with Sociedad Minera Corona S.A. for the purchase of the Cerro Corona deposit and adjoining mining concessions.

The environmental impact assessment in Cerro Corona mine approved on 2 December 2005, and in May 2006 began construction at the mine Cerro Corona.  Building of the Las Gordas tailings dam and quarrying for the relevant construction material commenced in 2007.

The mine production in Cerro Corona started  in September 2008, when the process plant started to operate. The Project Cerro Corona mine involves the production of gold and copper and  It is estimated that the current Mineral Reserve will be depleted in 2023

South Deep Gold Mine In South Africa Mining Methods And Gold Processing

South Deep gold mine which was formerly named Western Areas Gold Mine located in some 45 kilometers south-west of Johannesburg, in the districts of Westonaria and Vanderbijl park in the Gauteng province region of South Africa. South Deep gold mine has a depth of 2,995m below the surface, and is the world's deepest mines. South Deep gold mine in South Africa held by  Newshelf 899 Proprietary Limited (Newshelf) which is a 90% subsidiary of Gold Fields Limited and the remaining 10% is held by outside shareholders as part of the BBBEE transaction.

The South Deep Gold Mine lies at the northwestern edge of the Witwatersrand Basin, known as the West Rand Goldfield. The property covers an area of 2,469 hectares of surface (freehold) land and 3,563 hectares.

Mineral deposit in South Deep gold mine region of South Africa

South deep mine is located in the Far West Rand Goldfields and forms a part of the Witwatersrand Basin. The mine deposits lies beneath the Karoo Supergroup, Chuniesoort Group, Pretoria Group, Klipriviersberg Group and the Central Rand Group.

The Central Rand group comprises of detrital sedimentary rocks filled with quartz-pebble conglomerates. The gold deposits are interrelated with sedimentary features such as unconformities and fluvial channels.

The South Deep deposit has approximately 39.1Moz of gold reserves. The estimated uranium inventory at the mine is 37.5Mlb.

Gold Mining Africa

      Africa is a major producer of gold in the world, producing up to 30% of global production in gold mining africa. Africa has historically been recognized for its exceptional gold resource potential yet remains relatively under-explored. The opportunity to acquire prospective gold resource projects in Africa, and assure security of tenure, is often lost through failure to recognize and acknowledge the interests of local stakeholders.Although gold mining industry in South Africa is one of the global leaders in gold production, it also has the highest average production costs in the world. Coupled with labour problems, lowering grades as well as several mines reaching the end of their lives, it is not anticipated that South African production will increase in the future. Although Zimbabwe has historically been a prominent gold producer in Africa, political and economic issues could cause production problems for local producers. Tanzania and Mali are rapidly becoming Africa's newest gold producers with several mines being commissioned or in final feasibility stages. Ghana is still a major gold producer in Africa. Other countries contribute steadily to Africa's gold output. Much of the recent and ongoing success in tapping these areas' mineable gold reserves is simply due to the fact that low-grade (to 1.3 grams / tonne gold) near-surface (oxidised) ores can be recovered economically. A new challenge will be to economically recover low-grade sulphide ore by open pit and/or underground methods.

Martha Gold Mine Unique Open Pit Mining By Newmont

Martha gold mine constitute open pit mine that is very unique, located in the township of Waihi, New Zealand

Martha mines constitute open pit mine that is very unique, because the mining area is located in a residential area and near to a thriving community. With a population of about 4,700 people, the town of Waihi is situated on the east coast of the North Island of New Zealand.  Martha gold mine is  located in the township of Waihi, New Zealand. and owned by the Newmont Mining Corporation  a leading gold producer in the world.

Gold mining in Waihi has a history that spans three centuries. Gold was discovered in the 1800s and mined underground in the first half of the 1900s. The last 24 years of the 1900s focused on exploration

The Martha Mine has been operating since 1988. Martha gold mining project  was the first major hard rock mining operation to be commissioned following the resurgence of the gold mining industry in New Zealand in the late 1970s. The mining licence was granted for the open pit Martha Mine in 1987 and development and mining of the Martha Mine open pit. In the 2000s

The climate of Waihi is affected by its local topography. The rainfall in Waihi is relatively high, averaging in excess of 2,100 mm/year. Geology in waihi comprises predominantly rhyolite, with some dacite. The Waihi gold deposits are low sulphide epithermal gold-silver veins with associated volcanic breccias. The gold veins are hosted within a fine-grained volcanic rock, andesite, aged between 3 and 12 million years ago (Ma), during the Pliocene and Miocene.

Process Of Gold Mining In Super Pit Mine Australia

Super pit gold mine is the largest open pit mine

Kalgoorlie mine In Australia or better known as the Super Pit is located off the Goldfields Highway on the south-east edge of Kalgoorlie, Western Australia. Super pit gold mine is the largest open pit mine which has a hole a length of about 3.5 kilometers, 1.5 kilometres wide and 570 metres deep that make up the rectangle.

The Super Pit gold mine is owned by Kalgoorlie Consolidated Gold Mines Pty Ltd, a company owned two joint venture between Barrick Gold Corporation and Newmont Mining Corporation with respective shares of 50%

Kalgoorlie Consolidated Gold Mines Pty Ltd (KCGM) was formed to manage the assets and operations of joint venture partners, Normandy Australia and Homestake Gold of Australia Limited.

MINERAL DEPOSIT IN SUPER PIT GOLD MINE

Mineral deposit in super pit gold mine

Gold deposits Super Pit is one of the richest gold deposits in the world.  Composed of a series of mineralised faults known as lodes, a greenstone belt consisting of volcanic and sedimentary rocks and surrounded by extensive granite. These rocks all belong to the Archaean period of the Earth’s history and the goldfield is between 2.6 and 2.9 billion years old.  the deposit mainly occurs in a host rock known as the Golden Mile Dolerite.

The main host rock for mineralisation the Kalgoorlie district in Super Pit gold mine is the Golden Mile Dolerite, the largest of the dolerites in the area. There are two main styles of mineralisation. The Fimiston Style consists of classic Golden Mile lodes with abundant sulphides and tellurides. The Charlotte Style describes younger white quartz veins which are typically mined at Mt Charlotte, but have been found in other smaller deposits in the Kalgoorlie District.

The Golden Mile lodes have several characteristic orientations, each with slight variations in the style of the mineralisation. More than 1,000 individual ore lodes occur within the Golden Mile, some extending up to 1,800 metres long, 1,200 metres deep and 10 metres wide. They are all within an area over five kilometres long, two kilometres wide and more than one kilometre deep. The highest gold grades are typically associated with gold tellurides and alteration minerals with high vanadium contents.
