Gold Mining In Benin West Africa

by
Benin is an important mining country in West Africa. It is near Africa’s second largest gold producer; Ghana.It is in the same geological setting as the leading gold producer in Africa within the West African geographical formation.

Most of the gold in Benin is dominated by artisanal gold miners from the gold-Wealthy veins near the villages of Tchantangou and Kwatena in the Atakora Mountains in the Northwest region of the country. Gold has also from alluvial gold sediments from the Perma-river and its tributaries. 

Artisanal MiningMined In Benin

Not much of commercial gold mining been done in the country, but the authorities, the mining affairs in Benin, the Office BĂ©ninoise des Mines (OBEMINES) has been working with other state administration bodies of the country’s mining law with the aim of attracting foreign investment in the gold sector to revise.

Gold Mining in Benin is not new. It goes back to the pre-colonial period, was mined as alluvial gold along the rivers for the king. Most of the gold traded in the trans-Saharan trade came from rivers in present-day Benin and Ghana. 

Throughout history, the country’s alluvial gold was mined by artisanal gold mines along the rivers and in the mountains areas. Several studies have been conducted in the past to the presence of gold in the country, but limited commercial mining was started . This leaves a Large potential of gold mines to be explored in the country.

In same geographical location with some of Africa’s gold producers such as Ghana and Mali indicates that the country has great potential as a gold producer. 

Exploration Permits Are Issued

The government has received a number exploration licenses in international gold mining companies for gold exploration in the country in recent years. Most of these companies have taken the first positive results, which suggest that the country could have far more gold resources to be explored.

Quite a significant amount of gold mineralization has been discovered in two Alibori and Atacora regions. Alluvial gold contained , were also been found in several places outside these regions, so the widespread deposits. Further research is still to be determined in the commercial viability of gold resources.

Commercial Mining in Benin

Premier African Minerals Limited is an important AIM traded, natural resources and raw materials company with gold mining interests in Benin. The company, through its subsidiary G & B African Resources Benin SARL holds exploration rights in Benin. The company has an exploration license to a 249.75km2 mineral block in the eastern part of central Benin. 

The property is located Approximately 75 km north of the town of Parakou and has a great history of artisanal gold mining. Preliminary studies on the block done shows great potential of gold mineralization, although further studies are still needed before commercial gold mining can Start. 

The location of the gold property is particularly highlighted by Proterozoic gneisses migmatic. Since the early 2000s the area intermittently artisanal mining activities for tantalum and colored gemstones such as tourmaline and was seen blue beryl (aquamarine) .

The Ministry of Mining in Benin to facilitate all artisanal mining activities of mineral exploration and other commercial gold mining lately. A preliminary survey of the company based on satellite images of the license areas has identified 39 key areas for gold, tantalite and gemstones.

These objects are grouped into three bands pegmatite, one covers a length of Approximately 10 km, a second, a length of Approximately five kilometers and the third a length of Approximately three kilometers. The latter is especially potential for colored gemstones, the other two for both gold and tantalum.

Gold-Silver Project Hasbrouck In Nevada

by

The Hasbrouck gold-silver project is located in the northern part of Esmeralda County, near the town of Tonopah, Nevada, USA. The project is 75% owned by West Kirkland Mining (ERM) and 25% of Clover Nevada, a wholly owned subsidiary of Waterton Precious Metals Fund II Cayman.

The project is proposed to be developed in two phases. Phase I involves the development of the Three Hills gold deposit that is to be expected a production period of two years. Phase II is the development of Hasbrouck gold-silver deposit include, are likely to have six years. 

The pre-feasibility study (PFS) for the gold and silver project in Nevada was completed in June 2015 and the final approval from the government for the construction of the Three Hills Mine from April 2016. The Perform on the approval of Phase II under environmental assessment began in May 2015, the initial cost to the Three Hills mine is expected in production, is estimated to be $ 54.3 million, while Hasbrouck is funded from the production in Three Hills mine 

Hasbrouck Gold-Silver Project Reserves And Production

From June 2015, the Three Hills mine is proven to keep estimated combined and probable reserves of 9.65 million tonnes (Mt) grading 0.018 oz Au / t containing 175,000 ounces of gold.

The Hasbrouck Mine is estimated that proven and probable reserves of combined 35.671Mt grading 0.017 oz Au / t and 0.297 oz Ag / t, with 588,000 ounces of gold and 10.56 million ounces (Moz) of silver.

The hold annual production capacity of the project is estimated at an average of 71,000 ounces of gold. The project is expected to produce 138,000 ounces of gold at the stage in Phase II I and 429,000 ounces of gold, while silver production is estimated in the phase II to 194,000 ounces per year. 

Geology And Mineralization

Includes  , the two deposits are oxidized, low sulfidation, epithermal vein systems with host rocks tuffs and sediments of Siebert formation with limited mineralization within the underlying fraction Tuff. Gold and silver mineralization is either on the surface or near the surface, above the water level, and is open at depth and to a limited extent in the Northwest and East. 

Mining And Processing Of Gold And Silver Project In Nevada 

The Three Hills deposit is proposed to be mined as a run-of-mine open pit heap leach conventional open pit, truck and- shovel to integrate operations, while the deposit Hasbrouck be mined as an open pit heap leach ore crushed. The former is to integrate a 15,000t / d heap leach pad, while the latter incorporate a 17,500t / d leach pad.

The ore from two Phase II secondary cones with a primary jaw crusher, crushed crusher, and a tertiary high-pressure grinding roll (HPGR). The comminuted product is transported in a kneading machine with cement and to the leach pad. 

The leaching gold and silver from the Hasbrouck deposit and the gold from the Three Hills deposit at their respective locations with dilute cyanide solution that pass on through carbon columns to extract a precious metals.

The loaded carbon is then in adsorption-desorption-recovery (ADR) plant that are in the Three Hills . The loaded carbon from the Hasbrouck mine will be transported by trucks to the ADR facility. 

Infrastructure For West Kirkland Mining Flagship Project

The water required for the project is proposed to either be purchased from the Tonopah Public Utilities “(TPU) wellfield in Ralston Valley via an underground pipeline or installed next to each deposit wells.
“the two deposits are oxidized, low sulfidation, epithermal vein systems tuffs with host rocks comprising the sediments and Siebert lineup. “

The current for phase I of liquefied natural gas (LNG) -based generator are supplied, while the performance for the next phase of NV Energy supplied regional power distribution company, via a transmission line. A substation is on Hasbrouck location be built and both sides are a diesel-fired generator integrated to serve as back-up.

infrastructure for phase I, a laboratory will include a reagent storage building, a process Store and a warehouse, and serve three trailers as offices, will be relocated to Hasbrouck location in the next phase.

Important infrastructure at Hasbrouck site is building inclusion include administrative offices, a warehouse, a test laboratory and accommodations.

Gold Minerals And Gold Mining In Togo

by

Togo Top mineral is mined today is phosphate, where it counts 19 in the world. That’s Beautiful impressive, consider the relatively Little size of the country. Some trust that Togo may optionally also an important gold country, the fact that it is the immediate neighbor from Ghana, Africa’s second largest gold producer.

This led to speculation that Togo Large undiscovered gold resources. Early studies have returned positive results in terms of the availability of gold in the country. This has led to increase government investment in the sector looking for gold production in the country.
