There are Three Types of Engineers in the World Find out which type you are.


     In life, we always find ourselves in front of choices. Just this morning, I had to choose whether to drive my car to work or book a ride. Then, I had to choose whether to make myself an Americano or a cappuccino. Later today, I will have to choose between having salad for lunch or going for a sandwich. I expect that as soon as I arrive home, I will have to choose between taking a nap and going straight to the gym. We’re free to make choices – that’s part of being human in this day and age. But aside from what to eat, what to drink, how to go to the office or whether to exercise or not, perhaps the most important choice we have to make is what to make of our lives. Do we want to take up an active role in changing the world? Do we want to sit on the fence and watch other people do it? Or do we want not to care about anything at all? In most of my public speaking engagements in engineering conferences, I always break the ice by telling my audience how I believe that engineers, be they electrical, mechanical, civil, electronics, or chemical (of course, the list goes infinitely long), are the real superheroes of this world. But perhaps I have to clarify myself. I will tell you why in a bit.


See, from my more than 18 years of experience in the engineering industry, I have worked with more than a hundred engineers of a wide gamut of specializations. Based on experience, I can say that there are actually three types of engineers:

1. Engineers who make things happen. 
2. Engineers who watch things happen.
3. Engineers who say “WTF just happened?”

Engineers who make things happen are a joy to work with. They are ever curious and are always in active pursuit of solutions, not only to engineering problems in the office, but also to the world’s most pressing challenges. They are confident to discuss their ideas, and do not shy away from criticism. They have big audacious goals, daring, chivalrous and gallant in every task. More than talkers, they are doers: They are not content with delegating tasks; they do them themselves and show to their peers the right way. They do not slack: They are go-getters, and have a nose for excellent opportunities. They are consistent, but are ever ambitious to reach greater heights. Despite being so, they are realistic and are always focused on the fulfilment of their goals. The likes of Jack Welch, Michael Bloomberg, Larry Page, Sergey Brin and Elon Musk are some of the notable engineers who are visionaries and doers at the same time. They make things happen. In every project or task, they will either find a way, or make one. I call them “Engineering Champions.”





Engineers who watch things happen always prefer to color inside the lines. It is not that they lack aptitude or has low IQ. In fact, most of them have stellar profiles and tremendous engineering skills. However, these engineers always play safe, lacking the inspiration to do something meaningful, not persistent enough to make an impact and they just watch the world go by. They are usually quiet in meetings, and almost always agree with the ideas of others (I don’t know if they truly do, or they just want to avoid arguments). They are always ready to receive indications, but are never initiators. They are not exactly frustrated, but they seem to lack motivation to push the envelope of their abilities. To me, they are like birds always perched on a branch, hesitant to attempt to fly from fear of crashing to the ground.





Engineers who just wonder what happened are the irritating ones. You will hear them say: “WTF just happened?” Working with them is like pulling teeth. They usually zone out in meetings, and often seem detached from reality. They always see the negative in everything, and always have ready excuses when tasked to do something. They are the lazy, sluggish, indolent and slothful engineers who you often hear say “No, we can’t do that!” They are the ones who surrender before the battle even begins. They don’t seem to care that other engineers are excelling in their jobs; they are contented with mediocrity, and always have an air of nonchalance. I am sure you know someone who has this “clueless” character.



Like I said above, I will take this opportunity to clarify myself. Not all engineers are worthy to be called the real heroes of this world. The real heroes are the engineers that contribute in shaping the future. They are the ones that help surmount the impediments to social and economic growth of countries. They are the ones that make life easier and better for all humanity. They are the ones that leave a legacy for the future generations to enjoy. The real engineering heroes are making an impact, creating a social movement to fight poverty; re-engineering the food industry to fight hunger; engineering the chemical composition to fight diseases; and build affordable materials to improve humanity. They don’t just build tall buildings, large electrical power plants, chemical labs or mechanical engines, these engineers inspire people because they did something right. (They did something, and it was right thing to do). They’re like a magnet so powerful that you have to join their cause. If we can choose a blue shirt over a red, the Warriors over the Cavs, or beer over wine, perhaps we can also choose to make things happen, rather than sit on the sidelines or turn a blind eye on everything. So let me ask you, which type of Engineer are you?  Do you make things happen… watch things happen… or don’t have a clue what happened?






Are You Really an Engineering ”?



Are You an Engineer or Just an Engineering Graduate? What is the true essence of being an “engineer”?

Anyone can take up Engineering, but not everyone has what it takes to become an “engineer”. Sure, one can pass all his subjects, graduate, get certified and attain a title, but there is more to being an engineer than just fulfilling mundanities. Like what I said in a previous article, being an engineer is nothing short of super heroic, thus it comes with great responsibilities and immense challenges. With people looking up to engineers to provide convincing answers to the world’s most confounding questions, the onus is theirs to prove themselves worthy of such trust, regard and, if you will, reverence.


Engineers should make an impact to society

 Engineers are individuals endowed with the ability to understand the world through a different prism. They discern the mathematical and scientific basis of everything around them, and are thus able to analyze their surroundings through quantitative analysis. Engineers should apply this knowledge and skill to create a positive impact that will benefit the people of today and of generations to come. Formed by years of study, research and experience, real engineers should have the ability to solve the world’s most critical problems, be they in energy, environment, technology, transportation, infrastructure, healthcare or food, to name a few. Engineers should seek to create a better world for everyone. While professionals from other fields strive to understand and define what is, engineers breathe life to what ifs. For instance, biomedical engineers should spearhead the manufacture of medicines for the world’s deadliest diseases, like Cancers and AIDS. Mechanical engineers should invent machines that do not only operate with unparalleled efficiency, but are also respectful to the environment. Civil engineers should build more roads and infrastructure that will connect remote areas to economic and social centers. Electrical engineers should install power plants that will provide reliable electricity to communities with limited access to usable energy. Computer engineers should continue to create programs and applications that will integrate everyday activities and thus simplify the lives of millions of people.

Engineers should think outside the box. What box?

Engineers should ever be creative and inquisitive. Engineers should be able to transcend their comfort zones and venture out of the ordinary in search of the best solutions to the world’s grandest concerns. Engineers should always look to outdo themselves, and should never rest on their laurels. Imagine, had Apple, Samsung, LG or Sony engineers simply replicated the 5110, will we ever have today’s top-spec smartphones that have greatly contributed to our productivity? Had Airbus or Boeing engineers stopped improving aircraft, will we ever enjoy the comfort and safety of air travel that we have today? Had biomedical engineers gave up on finding a cure for deadly diseases, perhaps tuberculosis or malaria are still death sentences to anyone afflicted.

 


Engineers should remain steadfast

 The tasks at hand are enormous, so the profession is not for those looking for a stroll in the park. Engineers should have the heart of a lion and the resilience of a bamboo. Engineers will surely fail, and not once or twice, but many times over in their careers. There will be times when engineers will need to go back to square-one just when the end is within arm’s reach. There will be designs that will look good on paper and perform extremely well on simulations, just to flop on the prototype stage. There will buildings, bridges or roads that cannot be constructed as designed, due to various constraints. Engineers should not be fazed by such setbacks. Engineers should find the strength to march on and assume responsibility for their decisions and actions. They must always bear in mind the reason why chose to pursue the field in the beginning. They must always be proud of their chosen profession, and maintain their commitment to their avowed mission. At the core of the engineering profession should be a genuine regard for the well-being of others, an insatiable hunger for innovation and an unwavering dedication to the field. It would be impossible to define what makes an engineer in a short feature such as this, given its different facets, the complexity of character and varying definitions. However, I hope that I have drawn a visible line between a real engineer and a mere engineering graduate. So now, I give the floor to you, my readers. What do you think makes an engineer?

Caterpillar Plans to Sell Underground-Mining Equipment Lines

Caterpillar Plans to Sell Underground-Mining Equipment Lines

Caterpillar Inc. is retreating from the slumping coal industry, saying it plans to put its equipment lines for underground mines up for sale and lay off workers.

The Peoria, Ill., company said Thursday it will cut the workforce at its Houston, Pa., plant by about 155 jobs and will consider closing the plant if a buyer can’t be found. The plant produces a variety of coal-harvesting equipment and hauling vehicles and gear used in underground mines.

About 40 jobs also will be cut from a mining-equipment plant in Denison, Texas, where drills are made for underground mines. Caterpillar said it will stop taking orders for the for coal-mining equipment made at the Houston and Denison plants but will continue to support equipment already in use.

Demand for coal in the U.S. has fallen sharply in recent years as stricter environmental standards and low prices for natural gas make coal less attractive to burn in domestic power-generating plants. Caterpillar acquired the underground equipment lines as part of its $8 billion-plus purchase in 2011 of mining equipment company Bucyrus International.

“Caterpillar remains committed to an extensive mining-product portfolio,” said Denise Johnson, president of the mining-equipment business. “We firmly believe mining is an attractive long-term industry. At the same time, we continue to manage through the longest down-cycle in our history.”

Caterpillar is expected to log its fourth-straight year of lower sales in 2016. The mining-equipment business has been among the company’s weakest units recently amid slumping prices for mined commodities and reduced investments in mine expansions and new equipment. Caterpillar’s mining unit lost $163 million in the second quarter as sales dropped 29% during the quarter from a year earlier.

Caterpillar also announced it will revamp its plant in Winston-Salem, N.C. The plant has been producing powertrain components for giant trucks used in surface mines. But slumping demand for the trucks has left the Winston-Salem plant, as well as a plant in Decatur, Ill., where the trucks are assembled, severely underused in recent years.

The company said it will move the component assembly work to Decatur and repurpose the Winston-Salem plant for warehousing, machining or fabrication operations for its railroad-equipment business, Progress Rail. The Winston-Salem plant was opened in 2011 as part of a push by Caterpillar to expand production capacity, particularly for big mining trucks. But demand for the trucks began dropping shortly after the plant opened.

Newmont Mining Selling Indonasian Mine for $1.3 Billion

An aerial view of Bitu Hijau Open pit Copper and Gold mine.

U.S. gold producer Newmont Mining Corp. said Thursday that it would sell its 48.5% economic interest in the operator of the Batu Hijau copper and gold mine in Indonesia to local company PT Amman Mineral Internasional for $1.3 billion.

The announcement came as Indonesian-listed oil and gas company PT Medco Energi Internasional Tbk said it had acquired a controlling stake in PT Amman for $2.6 billion.

A group of Indonesian investors led by Medco had earlier expressed interest in purchasing as much as 76% of the mine operator, PT Newmont Nusa Tenggara. Medco said Thursday that it would join forces with an investment firm led by banker Agus Projosasmito and receive funding for the purchase from Indonesia’s three largest state-owned banks.

Japan’s Sumitomo Corp., Newmont’s partner in Newmont Nusa Tenggara, has also agreed to sell its ownership stake to PT Amman.

Newmont said the sale of its stake at “fair value aligned with its strategic priorities to lower debt, fund highest margin projects and create value for shareholders.”

“Our goal is to build a portfolio of long-life, low-cost assets with the technical, social and political risks we are well-equipped to manage,” Newmont Chief Executive Gary Goldberg said in a conference call to discuss the transaction, noting that earlier divestments have lowered risk.

The sale will involve a closing payment of $920 million and contingent payments of up to $403 million, Newmont said. Globally, Newmont has gained $1.9 billion from sales of noncore assets since 2013.

The latest deal, which is expected to close in the third quarter, comes as miners world-wide are re-evaluating their assets, having been hit by a slump in commodities prices. In early June, mining giant BHP Billiton Ltd. agreed to sell its 75% interest in Indonesia’s IndoMet Coal to local producer PT Alam Tri Abadi, in a move to pursue other growth options that BHP said were more attractive for future investment.

Colorado-based Newmont and Sumitomo operate the Batu Hijau copper and gold mine on the island of Sumbawa in Western Indonesia.

The mine—one of Indonesia’s largest copper deposits—has been a largely profitable venture for Newmont since it started commercial operations there in 2000.

Keeping production up, however, will require a hefty investment in the next phase of development at a time when Newmont has been hit by increasingly burdensome regulation and uncertainty about the future of its operating contract.

Jorge Beristain, a metals and mining analyst at Deutsche Bank, estimated that around $1.6 billion is needed for the next stage of expansion.

The company said its debt burden would “improve significantly” without Batu Hijau.

Some analysts had earlier said Newmont’s efforts to sell off its stake also suggests concerns about the long-term outlook for the Indonesian mining industry.

Vast deposits of copper, nickel and coal have lured foreign miners to Indonesia for decades and mining has contributed greatly to economic growth in the country. But growing nationalism and the desire among some officials to grab back control of the country’s natural resources has raised risks.

Rules issued in recent years have pushed foreign miners to divest majority stakes, pay higher taxes and royalties and invest in processing unrefined ores. By law, miners are also required to eventually shift from long-term contracts of work to a licensing system. Analysts and miners say the rules make little sense at a time when miners globally are re-evaluating their investments and Indonesia is trying to draw in more foreign capital.


After the rule banning the export of unrefined ores took effect, Newmont ceased exports and later declared force majeure on existing contracts. To receive an export permit—a biannual process—the U.S. Company has had to show it is making progress on refining or stop its shipments. Delays in shipments in 2015 caused Newmont’s fourth-quarter revenue to fall 10% from a year earlier.

The biggest issues facing Africa largest mining gathering – Indaba 2016


The biggest issues facing Africa& largest mining gathering – Indaba 2016
On Monday more than 7,000 delegates from 100 countries and territories across six continents will descend on Cape Town for the biggest mining gathering on the planet in one of arguably the toughest years in the history of African mining.

The continent is facing economic uncertainty, doubts over mining legislation and regulation, power cuts and looming strikes. Even the optimists, that is the government of South Africa, admit there could be as many as 32,000 jobs under threat in the country’s mines.

This would be a severe blow to an industry, that despite several setbacks in the last five years, is still top dog in Africa employing 400,000 people. Pay talks are expected in the platinum industry later this year, with the dominant union AMCU, that could lead to a strike costing billions and thousands of jobs. The union led a five-month strike in platinum two years ago.

AMCU will make its debut at this year’s indaba and is likely to arrive with characteristic uncompromising views on mining that could unsettle one or two foreign investors. 

“We feel it is not ok for corporations to come into our country make decisions about what is happening in our country and then leave,” says Manzini Zungu, the spokesman for AMCU.  

One of the highlights of this year’s gathering is that South Africa’s new mining minister Mosebenzi Zwane will open proceedings and give the mining world a hint of how his government plans to stem the flow of capital out.

For years a pall of gloom has formed over the Mining Indaba in Cape Town with analysts and industry insiders tutting about how pessimistic foreign investors are and how there are more supply companies and fewer mining companies every year.

“The problem is South Africa is sending out messages that it is closed for business,” one delegate and former mine boss said to me in Cape Town last year.

Infrastructure is also a worry. From  Zambia to Mpumalanga mines are suffering power cuts and a lack of roads, water and rails.

On the other side of the coin, infrastructure, along with the support for new mining projects, is the focus of the Mining Indaba with the aim of prising billions out of foreign investors.

The organizers are upbeat even if the mining industry is not. They claim billions of dollars in investment have been channelled in to African mining, through the indaba, creating 5,000 jobs since 2007.It claims 2,300 international companies will have delegates at this year’s gathering.

The Johannesburg Stock Exchange, clearly caught up in the sustained enthusiasm of the organizers, will be there in force in the hope of recruiting new listings. Of the 391 companies listed on the JSE, 68 are from metals mining and resources. The fact that the JSE wants more, at the very least, is a vote of confidence for a very battered industry that has seen billions in value of resources companies wiped off the board in the last few years.

When the talking starts in Cape Town there are likely to be more than a few sparks. One of the first speakers on Monday will be the former Nigerian Reserve Bank governor Lamido Sanusi, the man whose unflinching stance against corruption and his own government in 2011 earned him Forbes Africa Person of the Year award. The Emir of Kano, who rarely minces his words, will speak as chairman of Black Rhino Group , an energy infrastructure company with investments across Africa.

Other vociferous mining bigwigs expected as speakers will be Ben Magara, the CEO of Lonmin, Mark Cutifani, the CEO of Anglo American, Tom Albanese, the head of Vendanta Group, Robert Friedland, the founder of Ivanhoe Resources and Mark Bristow, the CEO of Randgold Resources.

There will be plenty of talk at the Mining Indaba, in Cape Town’s vast International Trade Centre, but talk can be cheap. If mining is to remain a major industry on this continent serious investment and hard work is needed this year.

More than 20 years ago the Mining Indaba was launched in one room at a Cape Town hotel. The industry must be careful not to allow the industry to shrink back into one hotel room in 20 years’ time.

New technique to discover copper deposits

Magmatic rock which formed large porphyry deposit in Chile.

A geologist at the University of Exeter has developed a new and relatively inexpensive way to establish whether certain types of magmatic rocks are more likely to contain valuable metal deposits.
In a study published in Nature Geoscience, Dr Ben Williamson, of the University’s Camborne School of Mines, together with Dr Richard Herrington from the Natural History Museum, London, have proposed a new method to explore for porphyry-type copper deposits. These deposits provide around 75 per cent of the world’s copper and a significant amount of molybdenum and gold which makes them extremely important to the world economy. The deposits, which originally form at several kilometres depth below the Earth’s surface, above large magma chambers, are relatively rare, particularly the largest deposits which are most economic to mine. In addition, most near-surface deposits have already been discovered. Any new method to locate deeper deposits is therefore of great interest to the mining industry.
The project, funded by Anglo American, a major global mining company, compared the chemical compositions of minerals from magmatic rocks that host porphyry deposits against those which are barren. A case study was then undertaken of a major new porphyry discovery in Chile, to test their theory. Minerals from magmatic rocks which host porphyry deposits have distinctive chemical characteristics which can be used as one of a suite of indicators to home-in on porphyry deposits. Unravelling the causes of the distinctive chemical signatures has also brought new insights into the formation of porphyry copper deposits, and more generally the generation of the magmatic rocks from which they form, which are an important component of the Earth’s crust. The main finding in this regard is that the magma chamber below the porphyry undergoes discrete injections of water-rich melts or watery fluids which enhance the magma’s ability to transfer copper and other metals upwards to form a porphyry copper deposit.
Dr Ben Williamson, of the University of Exeter’s Camborne School of Mines, said: “This new method will add to the range of tools available to exploration companies to discover new porphyry copper deposits. Our findings also provide important insights into why some magmas are more likely to produce porphyry copper deposits than others, and add to our understanding of how their parent magmatic rocks evolve.”

Kumba Iron Ore Ltd begins workforce reduction process

Sishen Iron ore Mine

Kumba Iron Ore, South Africa’s largest producer of the crucial steel ingredient, is slashing the workforce at its flagship Sishen mine by nearly half to cope with weak iron ore prices.

The Sishen mine, the largest source of iron ore in South Africa for decades, has undergone a major change because of the enormous amount of waste that had to be moved to expose ore.

The change has not been quick enough and majority shareholder Anglo American told investors last month a decision had been taken to shift focus away from volumes and instead focus on cutting costs, reducing capital expenditure and boosting cash generation.

The production forecast was lowered to 26-million tonnes a year at a unit cash cost delivered on board ships in Saldanha port of less than $30 a tonne this year, giving a break-even price of landing ore in China at below $40 a tonne.

As part of this new plan, the workforce would have to be cut, Kumba said yesterday. Of the 5,840 employees at Sishen, Kumba aims to reduce the number by cutting 2,633 direct employees and 1,300 contractor jobs.

Kumba issued the unions a section 189 notice on Thursday, starting a 60-day process to reduce the workforce.

“This has been an extremely difficult decision but, after exhausting all other avenues and doing all we could have done to reduce costs, we have no choice but to take more significant steps to preserve the viability of the mine,” CEO Norman Mbazima said.

Sishen is the largest single source of jobs in Kumba, which employs 7,434 people after it stopped mining the Thabazimbi mine last year, removing 1,160 jobs. In July last year, Kumba told the unions it wanted to cut 175 jobs at its Northern Cape mines — Sishen and Kolomela.

“It cannot be correct that as and when the mining industry is under distress the first casualties are ordinary employees,” said Lucas Phiri, National Union of Mineworkers chief negotiator at Kumba.

The dramatic fall in the iron-ore price, which Bloomberg pegged at less than a quarter of its peak in 2011 — hovering at the $41 a tonne mark — has put pressure on the iron ore producer’s balance sheet.

Kumba on Thursday reported a 12% drop in its fourth-quarter output to 10.04-million tonnes, dragged down by poor performance at Sishen. For the year, its output was down 7% at 44.88-million tonnes.

The Sishen mine was moving to a lower-cost pit layout and there was not enough exposed ore as the transition was being made.

Sishen’s output in the fourth quarter fell 17% to 7.7-million tonnes.

Kumba’s exports sales fell 10% to 10.5-million tonnes in the quarter and the company had a 4.7-million tonne stockpile, down from 6.5-million tonnes at the end of 2014.

Australian Coal Miner claims $3.3 Million for Workplace Injury


A Coal miner who claims he was permanently disabled in a workplace injury at a Moranbah site is suing BHP Billiton Mitsubishi Alliance for more than $3.3 million.

The man was injured in January 2013, when his arm was pinned while he unloaded cable reel at Moranbah's Broadmeadow Coal Mine.

Documents lodged in the Supreme Court at Rockhampton state the man was injured as he loosened the retaining bolts while unloading cable reel and "inadvertently placed his left arm into a pinch point position where it was pinned by an unexpected movement of the cable reel".

The man was pinned in that position for an hour.

The documents claim the man suffered "an extensive crush injury to the left upper arm with soft tissue and nerve damage from above the biceps to above the elbow joint" requiring multiple surgeries, including nerve grafting and tendon transfers. As a result of the grafting, he also suffered damage to nerves in both feet.

The man is suing the mining company for more than $3.3 million, including $180,000 of general damages for pain, suffering and loss of amenities of life.

The damages also include $1,787,000 for lost earning capacity into the future and $382,500 for future personal and domestic assistance.

A spokesperson for BHP Billiton Mitsubishi Alliance said the company took "the health and safety of all our employees very seriously and is focused on preventing injuries to its people".

"This is a concerning case which unfortunately involved a serious injury being sustained by one of BMA's employees almost three years ago. Since this incident occurred, BMA has sought to provide ongoing support to the injured employee ... for that entire period," they said. "Given this matter is currently subject to legal proceedings we cannot offer any further comment."

The World’s Largest Mining Dump Trucks


The dump trucks used in the mining sites are continue to grow larger, as most of the mining companies increasingly prefer big capacity dump trucks with greater functional efficiency. That’s why, the manufacturing companies try their utmost to bring out contemporary models of big-sized mining trucks to increase the productivity.

In this article Mining Engineers World presents you the details of the world’s top ten Mining dump trucks.

1.      Belaz 75710:
Belaz 75710, with payload of 450 mt, is the biggest dump truck in the world. It holds two Guinness World Records, for The Largest Truck Body and The Largest Two-axle dump Truck.

The Ultra-heavy dump truck was launched by BelAZ company in October 2013 under an order from Russian company Kuzbass. Sales of BelAZ 75710 trucks were started in 2014.

This massive Vehicle is 20.6m long, 8.17m high, and 9.75m wide. The truck has four-wheel drive and four-wheel hydraulic steering. It features two 16-cylinder turbocharged diesel engines with a power output of 4,600 HP. The 75710 uses electro-mechanical transmission powered by alternating current and has a top speed of 64 mph.

2. Caterpillar 797 F:
Caterpillar 797 F, the latest model of 797 class dump trucks manufactured and developed by caterpillar is the second largest truck in the world, with payload of 363 mt.

The truck is 14.8m long,6.52 m height and 9.75 m width. It features a Cat C175-20 four-stroke turbocharged diesel engine. The single block 20-cylinder engine utilizes a hydraulic torque converter transmission and offers gross power output of up to 4,000 HP and a maximum speed of 68 mph.

3. Unit Rig MT 6300: 
Initially, the truck was named as Terex MT 6300AC, introduced in 2008 by American manufacturer Terex. The MT 6300AC was rebranded as Bucyrus MT6300AC and became a part of Caterpillar's Unit Rig line after Caterpillar's acquisition of Bucyrus in 2011.

The body of the truck is 14.63 m in length, 7.92 m in height. The vehicle is equipped with a four-stroke diesel engine, with 20 cylinders and has a rated power output of the engine is 3,750 HP. The vehicle can move at a maximum speed of 64km/h

Ethiopia Government engages private sector to scale up Mining Activity


The Ethiopian government, along with private sector partners, is taking steps to tap the country's vast underground resources.

“Ethiopia has considerable reserves of gold, potash, zinc, gemstones and tantalum,” geological survey consultant Yalew stated. “But they remain unstudied, unexplored and undeveloped.”

Ethiopian Minister of Mines, Petroleum and Natural Gas Tolossa Shagi stated that the government is stepping up efforts to support the mining industry.
“There is hope that Ethiopia will become a country in the short term whose extraction industry will contribute significantly to GDP,” the minister said in an interview.

The minister pointed out that revenue from mining had not met its goal, as defined by the government’s economic plan for 2014. Ethiopia had planned to secure mining revenue of $646 million during 2014/15 but only earned about half of that, $363 million, according to government statistics.

“Within a period of two years, Ethiopia will start natural gas production from its Kalub and Lala areas in the Somali regional state where 7.4 trillion cubic feet of natural gas is being developed for domestic use and for export via Djibouti,” the minister said. The government is financing the project, in a public-private partnership with the Chinese mining firm GCL; GCL will also build the pipeline to Djibouti.

“Indications of much larger deposits of natural gas have been found along the Great Rift Valley stretching as far south as Uganda, and exploration is underway in this area,” Shagi said.

Russian company GBP Global Resources, which was granted the concession in 2014, is currently exploring natural gas and oil reserves along the Ethiopian Rift valley area. Revenue will be shared between the company and the government if reserves are found.

“Currently eight exploration companies including from China and Russia are engaging in exploration and development of natural gas throughout the country,” he said.

The Midroc Group, a company owned by the Saudi businessman Al-Amoudi, is developing gold in Southern Ethiopia. The miner Alana Potash, acquired by Israel Chemicals in March 2015, is working on the massive deposits of potash in northeastern Ethiopia, Bekele said.

Ethiopia is developing its gem stone industry. According to the minister, small-scale traditional miners and middle men are earning about $25 million annually from gem stones that are to be found in abundance in many areas in the country.

“This can be increased tenfold if we transfer gem stone extraction to the mainstream mining sector,” Shagi said. “That is why we have recently put in place a Gemology Institute.”

According to Bekele, only 350,000 square kilometers (135,135 square miles) in total have been studied using seismic techniques for reserves. Ethiopia covers a total of 1,100,000 square kilometres (420,000 sq mi).

“Exploration should be intensified covering an expanded study area,” Bekele said; satellite images and surveys on the ground show Ethiopia holding immense resources under the surface.
