Increased Diamond Production

RAPAPORT... Diamond mining companies are slowly raising their production levels even as many of ‎the major mines continue to face operational challenges. Theoretically, the trend should ‎ease cutters’ concerns about prevailing high rough prices and apparent supply shortages. ‎But it’s not clear that it will.‎

It hasn’t been an easy year for diamond cutters. In fact, many sightholders have ‎downplayed the value of their De Beers supply given the losses they incurred during ‎‎2012. ‎

Their anxieties continued in the first quarter of 2013 as rough markets have been ‎worryingly upbeat. Price increases have been driven by speculative trading on the ‎secondary market. ‎

As a result, diamond manufacturers have been caught between rough price hikes of ‎about 7 percent in the first four months of the year, according to Rapaport estimates, and ‎relatively stable polished prices. As of April 25, the RapNet Diamond Index (RAPI™) for ‎‎1-carat certified diamonds was up just 0.5 percent from the beginning of the year. ‎Manufacturing levels reflect a similar cautious outlook for the polished market.‎

If rough and polished markets are out of sync, a prospective increase in rough production ‎should offer some remedy to the market. Greater rough supply would ease the ‎competition for goods as well as dealer expectation that prices will rise in the short term. ‎It would also result in larger polished supply, alleviating the shortages in certain popular ‎categories.‎

Meanwhile, sightholder applications for De Beers supply for the year ahead are about 20 ‎percent below those made a year ago. Are they downplaying their expectations to avoid ‎the supply shortfalls they experienced in the past year? Given the recent market ‎volatility, it is perhaps better to err on the side of caution in planning the year ahead.  ‎

In contrast, the recent first quarter production data published by the major mining ‎companies suggest that supply should improve in the months ahead. Rapaport estimates ‎that global diamond production by volume rose approximately 4 percent year on year in ‎the first quarter of 2013. ‎

De Beers output increased 3 percent year on year to 6.364 million carats during the ‎quarter. Rio Tinto’s diamond production fell 4 percent to 3.2 million carats while the ‎combination of Dominion Diamond Corp’s production and at the Ekati mine – which was ‎owned by BHP Billiton during the period but has since been acquired by Dominion – rose ‎‎2 percent to 1.1 million carats.  ALROSA has yet to publish its first quarter figures and ‎were not available for comment at press time. One expects the Russian company’s ‎output to be stable as it has been in the past few years.

The production increases come despite operational challenges at a number of mines, ‎including at De Beers three flagship operations. At Orapa in Botswana, lower production ‎due to plant maintenance was offset by improved grades at the mine. Jwaneng continues ‎to recover from the impact of a slope failure in June 2012 and excessive rainfall at the ‎end of the year, while wet weather also disrupted production at the Venetia mine in South ‎Africa. Production at Rio Tinto’s Argyle mine continues to vary as the project shifts to ‎underground mining, with similar issues faced at its Diavik operation. ‎

These issues should continue to stabilize through 2013, raising expectations for higher ‎production.‎

However, the cutting sector should not get ahead of itself in expecting a sudden influx of ‎rough supply. The mining companies have set a new normal level of global diamond ‎mining since the 2008 downturn, one that is significantly lower than before the crisis. ‎

The result is that annual global production fell from its peak of 168.2 million carats in 2007 ‎to 122.4 million carats in 2011, according to the most up-to-date Kimberley Process (KP) ‎data. Rapaport estimates that production fell 2 percent to about 120 million carats in 2012 ‎and will stay at around that level in 2013.‎

Rather the increases will be gradual and one expects there to be a reasonable level of ‎supply given the current state of the diamond market. In counting the carats being ‎brought to market, if reported shortages prevail — and in fact are real — various factors ‎could be at play. Either the mining companies are holding back goods or selling outside ‎the market — as ALROSA sold to the Russian treasury (Gokhran) last year — or they ‎are selling at unrealistic prices so that there is not enough supply being sold at the right ‎price.  ‎

It is not clear whether either of these scenarios is currently prevailing in the market. ‎Hopefully, any reports of rough supply shortages are a function of high prices. There is ‎demand for every diamond at a price, and there may be rough prices that manufacturers ‎are just not willing to pay. ‎

As manufacturers maintain a cautious outlook for the polished market, there should be ‎sufficient rough supply at current levels of production. While mining companies hint at a ‎prospective increase in production for the rest of the year, there’s no real reason to ‎suggest rough prices will go up further. If they do, it is up to manufacturers to reject ‎supply and maintain equilibrium in the market. For the extra rough production means ‎precious little if the goods are polished at a loss. ‎
