In recent years, because Chinese enterprises have obtained most of the resource rights and interests of Simandou in Guinea, African iron ore resources have attracted the attention of Chinese people and people in the industry. It also ignited everyone's hopes for African iron ore, and even treated African iron ore resources as strategic resources.
On the one hand, we should be thankful for the success of China's layout of overseas resources. On the other hand, we should also see that the traditional European and American mineral developers have taken the lead, or even made the layout earlier than us. Today, we want to introduce the iron ore resource layout of a new Australian miner in the Gabonese Republic of Central Africa.
01 mineral resources and iron ore development in Gabon
Before learning about this company, let's first learn about Gabon's mineral resources and the local iron ore development.
Gabon, fully known as the Gabonese Republic (English: the Gabonese Republic; French: La R é public Gabonaise), is a stable central and western African country. It is surrounded by the Gulf of Guinea in the west, Equatorial Guinea in the northwest, Cameroon in the north, and the Republic of Congo in the East and south. The land area is about 270000 square kilometers and the population is 2.1 million. The capital and largest city is Libreville.
Gabon is a country rich in mineral resources and contains many economically valuable minerals. Its mining and oil production history can be traced back to the early 1960s. At present, Gabon's proven oil reserves are about 500 million tons, making it the fifth largest oil producer in sub Saharan Africa; Manganese ore reserves are 200 million tons, and its output ranks fourth in the world after South Africa, Australia and China, and its export volume ranks second in the world; However, Gabon still has iron ore, uranium ore, niobium ore, rare earth ore, copper ore, zinc ore and other resources that have not been developed on a large scale.
Gabon's economy depends largely on the world's demand for manganese and oil. Crude oil sales account for about 30% of Gabon's fiscal revenue. As Gabon seeks to reduce its economic dependence on oil and increase the contribution of the mining industry to GDP, the government is considering attracting investors to invest in mineral resources such as manganese, gold and iron ore.
Gabon has several famous iron ore deposits, including two rich ore areas, B é Linga and Mekambo, as well as lobi lobi, monts m'bilan, mebaga ngama, koumbi magnima, baniaka, etc.
It is worth mentioning that the B é Linga and Mekambo iron mines in the northeast corner of Gabon have proved to be among the richest iron mines in the world. It is estimated that the ore reserves with iron content of 60% ~ 65% in these two mining areas are as high as 1 billion tons, and the annual output can reach 20 million tons. Although iron ore was discovered in these areas as early as 1895, the first commercial mining license for iron ore was not issued until 1955.
We summarize several key lodes as follows:
B é Linga and its surrounding areas: located in the northeast of Gabon, it contains 1 billion tons of ore with a grade of more than 60%, and the potential DSO is hundreds of millions of tons.
Milingui: located in the southwest of Gabon, with a resource of 126 million tons so far.
Lobi lobi: located in the southeast central part of Gabon, with a resource of about 168 million tons. The average iron grade is about 41%.
Monts m'bilan: located in the northwest of Gabon, the resource is about 200 million tons, and the iron grade is between 38% and 45%.
It needs to be said that before, state machinery group (sumeda's parent company) planned to invest US $3 billion to develop the Belinga project, which ended in fruitlessness.
02 Australian company in Gabon for 9 years
The Australian mining company we want to introduce today will be located in Gabon, Africa in 2012. In 2012, the company applied for an iron ore exploration and mining license in baniaka area in Gabon. Now it has 100% interests in six exploration licenses in Gabon, covering three projects, covering an area of about 5270 square kilometers. This Australian company is Genmin Limited (hereinafter referred to as Genmin).
Genmin is a listed company. The company obtained and applied for an African iron ore exploration license as an exclusive joint stock limited company on January 11, 2010.
According to Australian media reports, the company was sold to South African giant exxaro resources at a price of a $350 million in 2012. Joe ariti, the founder of the company, remains the main shareholder of Genmin, and Tembo capital, a small mining private equity investor, is also included in the company's shareholder list.
Genmin Co., Ltd. was transformed into a public company limited by shares on July 17, 2014.
The three 100% equity projects held by Genmin are:
• baniaka iron ore project (feasibility study stage)
• bakoumba project (advanced exploration phase)
• Minvoul / Bitam project (early exploration stage)
• extensive cooperation with the Gabonese government (Owendo port, iron ore port of ovindo, setrag, Gabon railway operation company)
• banyaka iron ore project is a key planning project in Gabon
The banyaka iron ore project owned and 100% owned by Genmin: (baniaka) includes two exploration licenses of banyaka and banyaka West, with a total area of 881 square kilometers. Banyaka is currently the most well planned project of Genmin. The exploration since 2013 has determined that the cumulative mining length of iron ore vein is 85 km, which has been subdivided into 12 main development ore occurrences.
Genmin defines the control and inferred resources of the banyaka iron ore project in accordance with the Australian code for reporting exploration results, mineral resources and ore reserves (JORC), with a total of 260.4 million tons of iron ore. This makes the banyaka iron ore project one of the main mineral deposits in Gabon.
Bakoumba project includes two licenses of bakoumba and mafoungui, covering an area of 1836 square kilometers. Baniaka and bakoumba are located in the Archean Chaillu Hill block in the southeast of Gabon; The Chaillu Hill massif extends southward to the Republic of Congo and covers the mayoko and zanaga iron ore deposits.
The Minvoul / Bitam project includes Minvoul and Bitam licenses, covering an area of 2825 square kilometers. Minvoul / Bitam is located in the hills in northern Gabon; The iron deposit area extending northward to the border between Cameroon and Congo also has exploration and mining rights.
What is the iron ore quality of 03 Genmin?
The most representative of Genmin is the banyaka iron ore project. Since 2013, an iron ore area with a length of 85km has been explored, and 12 main development ore occurrences have been subdivided, which are composed of clastic iron deposits (did: detrital iron deposits, formed by layered iron deposits (bid) eroded, collapsed or alluvial) and BIF banded iron formations, which are divided into three main mining areas, The details are as follows:
·The phase structure of banyaka iron ore is composed of the first layer of clastic iron ore deposit (did) and the banded iron ore deposit (BIF) of oxide layer. The thickness of clastic iron ore deposit is about 1 to 16 meters.
·The second oxide iron ore deposit is distributed 20 to 70 meters below the surface.
·The third layer is the magnetite (primary) deposit (which is still in the exploration stage).
The main focus of Genmin exploration is clastic iron ore deposit (did) and oxidized iron ore.
According to its third quarter report on the Australian Stock Exchange, the iron grade of the first five industrial grade test samples of the banyaka iron ore project reached 65%.
Genmin company conducted pilot test on iron ore samples in banyaka mining area and produced high-quality lump ore and fine ore with a grade of 65.1%
This large-scale test was carried out by bond equipment, a professional mineral processing and engineering company, in South Africa. The purpose is to formulate engineering level process design standards and confirm the product output, grade and quality of the project. A total of 13 samples were sent to bond for pilot plant testing from the mineral resource cladding in the exploration areas of flouflou, bandjougoy, tsengu é and bingamba North in baniaka mining area. Among them, 7 are clastic iron ores of the project and 6 are oxidized banded iron ores (soft and complete oxides), with a total wet weight of about 22.4 tons.
The grade of high-quality block and powder returned from Clastic iron ore samples are 64.1% and 65.1% respectively, the average block yield is 42%, and the ratio of block to powder is expected to be 42% and 58%. When the mass yield is 30% ~ 45%, the grades of lump iron and fine ore products of two soft oxides (oxidized banded iron ore) reach 62.3% and 65.4% respectively.
Genmin company also hired Central South University in China to carry out sintering cup and other tests on the samples of block and coarse powder products provided by it.
The latest development of 04genmin exploration
According to the announcement of Genmin company on November 23, the company has completed the drilling of oxidized ore at bandjougoy ore point of banyaka project.
The company drilled 25 boreholes in the clastic iron ore deposit (did) of the project, with a total drilling footage of about 3000 meters. The target is the downdip extension of the iron mineralized area of the existing ore body, and the possibility of deeper oxidation and iron enrichment along the structure of the newly interpreted mineralized section is tested.
Recently, Genmin has conducted on-site exploration of banyaka project again
Genmin obtained oxide and primary mineralization at the downhole depth predicted during the drilling plan and confirmed the existence of a large-scale flat mineralization system at or near the surface.
The main boreholes with obvious ore occurrences are:
-See ore spacing: 31.3m, drilling grade: 44.4% Fe, hole depth: 10.3M
-See ore spacing: 49.1m, drilling grade: 40.9% Fe, hole depth: 7.5m
-See ore spacing: 40.0m, drilling grade: 40.9% Fe, hole depth: 3.0m
Bandjougoy ore body is 4.4km long, and the belt iron layer (BIF) with the extension range of no fold ore body of 6.3km is the largest single exploration target area for oxidation mineralization of banyaka iron ore project. At present, there is no resource that meets the JORC standard. Its in-situ oxidation exploration target is between 67 million tons and 124 million tons, and the iron grade is between 35% - 49%.
Genmin's drilling confirmed that the ore body of the banded iron layer (BIF) tilts northward between 30 and 40 degrees, and the real ore body thickness is 55 to 60 meters. The main mineralized area of the banded iron layer (BIF) is still open at the depth of. This is a strategic objective to identify an important potential late magnetite asset in the exploration area.
It should be noted that the shipment of banyaka iron ore project will be transported to the port of ovindo by trans Gabon national railway. At present, Eramet, France, transports its manganese ore to the port through the railway. The distance from banyaka iron ore project to Gabon railway is about 60km.
30 km north of the banyaka project, there is a hydropower station with a total installed capacity of 200 MW. The power station is constructed and operated by Sinohydro.
As of September 30, Genmin held more than a $22 million in cash, which is mainly used to complete the pre feasibility study of banyaka project, which is expected to be completed by the end of the first quarter of next year.
