Newmont Mining Selling Indonasian Mine for $1.3 Billion

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.

Death caused due to Carbon Monoxide Poisoning in an Underground Copper Mine


What is Carbon Monoxide?
Carbon monoxide (CO) is a highly poisonous substance produced by the incomplete burning of gasoline, wood, coal, oil, propane gas, or anything else that contains carbon. The primary danger with carbon monoxide is that it cannot be easily detected. Carbon monoxide is a colorless, odorless, tasteless gas, and thus gives its victims no advance warning. Commonly referred to as "coal gas" or "white damp".

What is carbon monoxide poisoning?
Carbon monoxide poisoning occurs when you breathe in even small amounts of the gas. When you breathe in carbon monoxide, it gets into your blood stream and prevents your red blood cells from carrying oxygen. Without oxygen, your body tissue and cells die. Levels that do not kill can cause serious harm to health when breathed in over a long period of time. Long term effects of carbon monoxide poisoning include Paralysis and brain damage.


CARBON MONOXIDE POISONING – WHAT ARE THE SYMPTOMS
The most common symptoms of carbon monoxide poisoning is as follows
  •         headaches
  •         dizziness
  •         nausea
  •         breathlessness
  •         collapse
  •         loss of consciousness

Occurrence of Carbon Monoxide in Mines
Carbon monoxide can be found in underground and surface mines in poorly ventilated or confined spaces. At typical mining operations the most common sources of CO are internal combustion engine exhaust, Spontaneous combustion, Coal dust explosions and explosives detonation. In coal mines, CO can also be produced by the low temperature oxidation of coal. Ambient levels of CO in mine atmospheres may vary depending on the characteristics of the coal. Elevated levels of CO are commonly found adjacent to gob areas and in bleeder entries and must be carefully monitored. 

During recovery operations following underground mine fires or explosions, special attention must be given to the detection of CO. Although fires and explosions are rare events, they can produce significant volumes of CO.

Precautions against Carbon Monoxide poisoning in Mines

  •        All working places should be supplied with fresh and adequate air.
  •       Proper training in the use of CO detectors and procedures to follow when CO is detected.
  •      Proper checking should be done after every blast for CO gas by a competent person.
  •      Carry Carbon Monoxide Detectors to the work places by mining Supervisors.
  •      Don't allow to store gasoline, carbonaceous and wooden  material at Working Places.

Treatment for CO poisoning
Treatment for CO poisoning includes removing the victim to fresh air and rest. If the victim has lost consciousness a medical emergency has occurred and immediate emergency medical attention is required. Medical technicians will administer oxygen and transport the victim to the hospital for additional treatment. Fortunately, most CO poisoning victims recover completely.
