The latest OMF Metals Report by Kevin Morgan:
Be careful for what you wish for! Â ?After an extended period of low volatility global markets have been shaken up thanks to an escalation in the Greek saga and Chinaâ€™s announcement of a wave of new measures in an attempt to halt the collapse of the Chinese stock markets. Traders love volatility, until theyâ€™re actually faced with it.
The dominant story has been how the Greece â€˜Noâ€™ vote is going to play out. The situation looks messy to say the least and we look to be in for several weeks of market turbulence as the Europeans and the Greeks try and resolve their differences. Â ?European Creditors donâ€™t seem to realise that the current approach has not worked, and are demanding more spending cuts and tax hikes that will see the economy shrink further. On the flipside, the Greeks turned up to last nightâ€™s Eurogroup meeting without any new proposal, and with the attitude that a No referendum vote was somehow a victory for their bailout negotiations.
Against this backdrop of uncertainty and speculation in Europe, Chinese stock markets have been plunging 30% in the past three weeks. Yet thereâ€™s been a distinct lack of safe haven buying. Sure a strengthening USD is a headway for commodities, but I believe the real issue is â€˜Greek fatigue’. For too long this story has promised so much, for the bullion investor, and for so long thereâ€™s been a 11 hour concession. Many still believe some sort of interim compromise will be reached to keep Greece limping along.
Last nightâ€™s capitulation in precious metals, which saw Silver and Palladium plunge over 5% at one point, was based on frustration, but shouldnâ€™t have come as any surprise to technical traders. Prices been languishing so perilously close to major support levels, that any minor setback in prices would trigger a bulk of pre-set sell orders just below recent support.Â ? My view is that last nightâ€™s capitulation is an opportunity. Bullion prices priced NZD have risen and benefitted from a recent fall in our currency. Now, following this clean out of the nervous bullion investors, an opportunity has arisen to benefit from undervalued metal prices.

Hi all, Gold had another wait and see week, treading water around US$1182 per oz. awaiting news on another Greek deadline due this Thursday. Today also marks the beginning of the FOMC’s two day meeting. The US central bank isnâ€™t expected to raise interest rates, however many in the market are now factoring in a likely increase later in the year, with most punters picking September. Speculation has therefore favoured the USD, edging higher, and in turn weighing on commodities and commodity currencies such as the Kiwi. The good news for Gold traders is that the Kiwi has fallen faster and further than Gold and Silver, pushing up Bullion prices in NZ terms.
In uncertain times you can be sure of one thingâ€ ? volatility!. With talks having stalled ahead of the technical deadline for an agreement on Thursday, the likelihood of a deal being reached is now almost non-existent. Â ?The Euro group finance ministers meeting is still scheduled to decide the â€œfateâ€ ? of Greece, but there have been so many of these meetings it is hard to see this one producing anything concrete. It also looks like the market has become complacent, anticipating another last minute deal to be reached, so hence traders arenâ€™t jumping into Goldâ€ ? yet.
While Gold has had the benefit of safe haven support, the rest of the precious metal complex have struggled. Platinum and Palladium both are being dragged lower by a risk off sentiment swirling around the stock markets. Already this month Palladium has lost 6% to now trade at US$1,080 per ounce and Platinum has dropped approximately 3% to $732.45 per ounce.
Iâ€™m not a betting man, but I canâ€™t see the benefits of selling precious metals at current levels, especially this close to major technical support and with such large event risk looming. Â ?Buying Call options appears best strategy ahead of tomorrowâ€™s announcements.
By Adam Van Sambeek, Treasury Manager.
Last week I noted Gold’s test of the resistances just over US$1200, now we’ve seen long held support come under pressure this week. This all stemmed from last Fridays much watched US employment numbers which exceeded estimates, driving up expectations that the Fed would move sooner rather than later to increase interest rates. The resulting speculative jump in US dollar saw Gold fall below long held support around US$1175, which in turn triggered protective Sell stops placed just below this key level, spiking prices to US$1162 lows.Â ? Gold had declined in four of the five sessions last week as US data gradually confirmed the Federal Reserve recent minutes, which said declining first quarter growth was due to temporary factors like the unseasonably harsh winter. The Fed removed all calendar references in its forward guidance and said that recent economic weakness might be “transitory” in nature. This means that bank is now entirely dependent on data so a rate increase could happen at any future meeting.
Meanwhile in Greece, the country delayed last Fridays 300-million-euro repayment to the IMF until the end of June, increasing the risk of a Greek exit from the bloc. Concern over this situation however has failed to propel interest in gold. With investor sentiment for gold so weak, gold prices may well continue lower but I feel this is leading to a better buying opportunity. And given developments in Greece and with the potential for corrections in other asset classes, it may not be too long before the markets start looking for a safe haven again.
As for Silver, this has dropped below the $16 mark for the first time since May 1 and has struggled to regain and hold this level. Currently we’re sitting just below that at US$15.968 per oz. Technical charts indicate that we’re sitting on an ascending support line, which originated in March of this year. Silver should be viewed as oversold and therefore valuable to a corrective bounce. I’m a buyer of Silver at these levels with a protective Stops at 16.87.

Following from last week’s postÂ ?we will share some information on working with red gold alloys, particularly tips around melting, cooling, and fabricating.
Common practice for red alloys after heating/annealing is to allow the metal to come off red before quenching.
Because of the quantities of Copper necessary for the colour of these alloys upon casting a large grain structure can occur. This can result in grain boundary separation/cracking.
Ways around this if applicable are pouring a smaller ingot or annealing the metal prior to working.
Some reds require air cooling after casting whereas others can be quenched once the red glow has dissipated or they can be immediately quenched into hot water.
Once an alloy has been worked down and annealed/heat treated then its structure can balance out to a more user friendly condition. This is the stage our customers would receive the metal.
So at this stage as an alternative to air cooling quenching in hot water can be beneficial as the element of shock is reduced.
Quenching into water that contains a small amount of alcohol i.e. 5% of methylated spirits or Isopropyl alcohol will help with surface oxidation.
All alloys behave differently.
Methodical testing will give definitive results. i.e. Air cooling/quenching but this is not always possible for a Jeweller who has limited product.
Breakdown should be restricted to 50% or twice the original length after elongation although some alloys respond better to higher percentages. Too little work and frequent annealing can have adverse effects.
Our general fabrication annealing temp. is 650Ëšc or by hand torch/eye a dull red. A controlled atmosphere always produces better results when annealing red alloys.
Here are links to websites where you can learn about soldering based onÂ ?extensive testing on a range of different solders and alloys:

With the increase in popularity of red gold alloys, we thought it would be appropriate to share some information about what makes these alloys unique and how to address challenges that arise from the special properties of red golds.
-Â ?Â ?Â ?Â ?Â ?Â ?Â ? Composition of Red Gold Alloys.
Red gold alloys are characterised by a relatively high copper content. Copper has a higher melting temperature and different structure to gold and silver. This means that red golds can behave quite differently to most precious metal alloys. Lower carat red gold in particular may have a higher overall percentage content of copper, creating challenges when working the metal.
-Â ?Â ?Â ?Â ?Â ?Â ?Â ? Difference between Rose, Pink and Red gold.
Typically, red golds are described as either Rose, Pink or Red. This may vary between suppliers and recipes and is mainly based on the colour. Here are some typical examples for 18 carat red golds:
18K Red gold: 75% gold, 25% copper
18K Rose gold: 75% gold, 22.25% copper, 2.75% silver
18K Pink gold: 75% gold, 20% copper, 5% silver
Next week we will share some information on working with red gold alloys, particularly tips around melting, cooling, and fabricating.
It may be a shortened week, but already we’ve seen plenty of excitement. Monday saw a surprising spike in Gold prices, making a brief foray above $1,200, but with very little follow through, prices quickly retreated. I couldn’t find any explanation for this sharp jump in price, except that Mondays are notorious for thin volumes, and being the first day of the new month, we tend to see a fresh allocation of managed funds hit the market. Once again, Gold prices settled back into the regular trading range between US$1175 and US$1225.
Meanwhile, Greeks and officials from the ECB and the IMF remain locked in negotiations. Greece looks set to make a first repayment of 300 million euros to the IMF on June 5, but it’s still unclear how it will pay off the rest of its debt. The immediate concerns surrounding the looming debt deadline may have eased, diminishing part of gold’s safe-haven appeal, but it may not all be bad for Gold. If a deal is struck, its highly likely to see a resurgence in the Euro, driving US dollars lower and overall benefiting commodities. Last night’s upbeat German unemployment data and positive Greece talks saw the euro claw back 2.5% against the US dollar, its biggest gain in nearly 3 months.
Looking at other precious metals, Platinum has been the worst performing metal in the sector, sliding 1.4% through May. Palladium didn’t fare much better dipping 0.6%, underperforming Gold, which gained 1.5% and Silver, up nearly 4% on the month. I can’t find sufficient reason for the under-performance by the PGM’s, so I’m buying Platinum, particularly at current levels around US$1100.

After a data filled week, precious metals still remain in relatively tight trading ranges, barely changed from this time last week. While weâ€™ve still experiencing some whippy trading sessions, the ultimate outcomes have done very little to denote direction. Â ?Friday’s much anticipated US non-farms payroll data was viewed as positive on meeting market expectations. Revisions lower from last monthâ€™s pervious report perhaps tempered traders relief following a recent string of weaker economic releases. Although one piece of less negative data shouldnâ€™t rise expectations of interest hikes happening anytime in June.
Across in China, news of further stimulus from Chinaâ€™s central bank cutting their one year lending rate by 25 basis points to 5.1% should have a positive flow on effect for commodities. These changes are aimed stimulating their slowing economy to reach its 7% growth targets. Expectations are that this is not the last stimulus, with further easing to follow in the coming months. Lack of commodity demand out of China certainly hasnâ€™t gone unnoticed by the precious metals sector.
Closer to home, weâ€™ve finally found some relief from a high NZD. Since the NZ Reserve Bank hinted it would cut interest rates if demand weakens and inflation remained low, many major banks have come out revising their interest rate forecasts. ANZ Bank is calling for interest rate cuts in both June and July, along with First NZ Capital calling for cuts. This resulted in sharp 2 cent correction in the NZD/USD. Adding fuel to calls for interest cuts, NZ employment data released late last week showed our unemployment rate for the first quarter remained at 5.8% vs expectations of a drop to 5.5%. Â ?Our rock star economy may be having Justin Bieber like fall from fame. This isnâ€™t of course all bad, those holding Gold paid in NZD will be reaping the benefits. So noted in this report, Iâ€™ve fancied Gold in NZD terms, therefore the recent demise of NZD has seen Gold values in NZD climb 2%, while USD pricing remain stagnant.
Golds trading patterns appear to be forming a wedge, with declining highs, but with lows remain unbroken, forming progressively resilient support. This doesnâ€™t mean that we can now assume a price floor is in place, it just highlights strong demand for Gold at the US$1150-1170 per oz. area. On the topside, weâ€™ll need a break of US$1205 per oz. before we can feel more convinced about future higher prices. Â ?Otherwise we have a clear trading range in which we can sell into spikes around US$1200-1205 with protective stop losses close to US$1210 -1215 per oz. However, my preference is to buy on dips around US$1175-1180 per oz.

How does wire get from square to round? Check out my short new video!
Apart from the high temperatures involved, platinum alloys weld readily without the need for fluxes. Because filler metal, if needed, is the same as the components to be joined, it is easily possible to close the seam without any visible colour change. This is a decided advantage in sizing rings, for instance. Even so, it is good practice to minimise the amount of filler needed (whether welding or soldering) by making joints as closely and accurately as possible; platinum alloys do not readily bridge large gaps with filler metal (which is not pasty at any stage).
The absence of fluxes, except for the lowest melting point solders (where the flux is to protect the solder, not the platinum – see below table), means that the usual adhesiveness of flux cannot be used to support the solder paillons in place. In practice, a small amount of non-borate flux may be used for this purpose, although it is not necessary metallurgically. Alternatively, solder may be clipped in the joint or supported by a thin extension of stock wire that is allowed to melt free at the last moment.
Silver again out-shined with a 3% gain, Palladium + 2%, while both Gold and Platinum traded 1.5% higher from the same time last week.
Trading hasnâ€™t been without some trepidations, bullion traders once again closing positions into the weekend. Â ?Fridays have now become renowned for this mass exodus of risk. Gold sinking to six week lows, breaking below $1,170 per oz. before clawing back slightly into the close. Even a falling US dollar and generally poor US data didnâ€™t support Friday’s metal prices.Â ? Recognising this trend allows us to identify opportunities and eliminate panic decisions. Monday saw safe-haven buyers back in the market after developments in the Middle East over the weekend and bargain hunters restore last weekâ€™s Gold losses. Though the recovery did pick up steam following last nightâ€™s US data miss, temporarily reaching key psychological $1,200 level, to currently settle just below at $1,195.
Fundamentals are slowly moving back in the favour of holding precious metals. Physical demand in Asia appears to be picking up again at the currently lower prices. While US data fails to deliver promised growth. Overnight, US trade deficit of $51.4 billion was much larger than the expected $41.2 billion and the worst reading since October 2008. This highlights the dollar’s strong headwind effect on US manufacturing, eroding the country’s global competitiveness. Â ?How long can the US dollar maintain present strength?
Looking ahead, most participants should remain cautious ahead of Friday’s blockbuster US non-farm payroll data, which is forecast at 231,000 in April, after an unusually weak reading of 126,000 in March. Following some soft US numbers and the central bank’s shift to a data-dependent stance of monetary policy, the data could provide clues on when the Federal Reserve will raise interest rates, and therefore the direction of precious metals dominate pricing factor, the US dollar.

After weeks of low volatility range trading, precious metals finally broke trend, with sharp losses seen last Friday, with Gold settling below the key support of $1180.Â ? Fridays have been particularly bearish sessions as investors concerned with holding long positions over the weekend opt to close positions out.Â ? Rumours that Greece was closer to a bailout deal after Thursdays summit of Eurozone ministers fuelled those concerns.Â ? However, the Greek debt situation still appears far from over, especially after Greek Prime Minister demoted lead negotiator and Finance Minister following months of ineffectiveness in resolving the countries debt obligations. This saw the yellow metal regain lost ground to close nearly $30 higher on Monday.Â ? In fact we’ve witnessed a complete turn-around in the fortunes of precious metals. On the one week performance, Silver led the surge higher jumping 6.1% higher, while both Platinum and Gold climbed 3% from this time last week.
Meanwhile, the US dollar index has been dragged lower, after disappointing U.S data (weaker Consumer confidence) and dampened expectations that the Fed will hint at this weekâ€™s FOMC of an imminent rate hike. This is the latest in a series of lacklustre data from the states, with yesterdays the US flash services PMI also missing consensus.Â ? A weaker USD is positive for commodities like gold which are priced in USD as it makes them cheaper for non-dollar users. Unfortunately the weakness in USD has also pushed commodity currencies such as the NZD higher. So in NZD terms, Gold is still hovering around the $1600 NZD per oz. level.Â ? Undervalued on medium term charts.
Looking ahead, the next 24 hours should be very eventful.Â ? Tonight we get an update on US 1st quarter GDP with estimates as low as just 0.1% annualised.Â ? Followed by tomorrow morningâ€™s Federal Open Market Committee meeting.Â ? Then closer to home, we get the latest thinking from our own Reserve Bank. Expectations are that they will try and talk the NZ currency down given how low inflation is currently running. Personally I’m looking for higher levels in the NZD/ Gold levels in the coming week.

Gold consolidates just below the $1,200 per ounce with no fresh news or direction for traders to latch on to. Renewed dollar strength follows unclear FOMC minutes, which could’ve been interpreted anyway to suit your own view on the FED’s ultimate intentions. This is capping any sustained Gold rally.Â ? Gold failed to hold key 1205 support, after briefly climbing to 1224 just before Easter, returning to its high volume comfort zone of around 1200.Â ? Traditionally, precious metals now enter the seasonally-low period where physical demand historically declines. However, the yellow metal is showing resilience, with higher lows and higher highs, with the next few trading sessions crucial for bulls that we maintain above the 1190 level.Â ? Last night did see this level break, only to claw back losses, closing at $1193, after weaker than expected US retail sales and slump in small business confidence.
Interestingly, the Commodity Futures Trading Commission (CFTC) reported that the Comex speculative traders increased their net-long positions in gold to 100,757 contracts, which marks a five week high, up from 80,019 a week earlier.Â ? A sustained build in price and an adjustment in current bearish sentiment, could rise the likelihood for further long accumulation and short-covering in the coming weeks. However this still poses risks, as this data proves the market remains highly speculative, and therefore vulnerable to price swings. Good news is we’ve already seen Crude oil prices recover 15% over the past month, leading a small commodity revival, as investors seek value in beaten up sectors. Will Gold and Silver follow suit?

It shouldnâ€™t have come as any surprise that following last weekâ€™s meteoric rise in Gold, involving the longest winning streak in over a year, we would witness some sort of correction. The pullback in gold picked up steam after Federal Reserve chairwoman Janet Yellen said late on Friday that an increase in the benchmark federal funds rate “may well be warranted later this year” given a sustained improvement in US economic conditions. This was enough to see Gold prices retreat back to $1180 support, having stumbled around the $1200 psychological resistance. Many may argue that last weekâ€™s rally is in fact the correction to a market in a strong downward trend. That may be the case, but more weight should be placed on Goldâ€™s recent resilience and how convincing $1150 support has become.
As stated many times before, USD is the main driving force for commodities, and in particular the increasingly public debate on when the Fed will raise interest rates. Â ?This has become highly speculative, with traders forecasting the Fedâ€™s next move anytime data is released. Last nightâ€™s data was no exception, a weaker-than-expected ADP employment report followed by disappointing ISM Manufacturing data saw traders selling USD, with subsequent gains for commodities. Â ?This heightens volatility in an already uncertain market, making trading decisions increasingly difficult. Donâ€™t expect any respite as we head into Easter, Employment and Non-Farm Payrolls are due tomorrow night, and in a holiday thinned market, expect volatility. (Non-Farm Payrolls are expected to show an increase of 245k with the Unemployment Rate holding at 5.5%.Â ?)
I particularly like Bullion priced in NZD. Last nightâ€™s disappointing Global Dairy Trade auction saw the index fall 10%, while New Zealand Whole Milk Powder falls 13.3%. All this should put NZD under pressure, which is long overdue for exporters into Australia whoâ€™ve been suffering a near parity exchange rate of late. Happy Easter everyone.

Gold backed up last weekâ€™s price gains, climbing back above our previously mentioned US$1180 resistance, reaching a 3 week high of 1195.30 overnight. Â ?Prices are on course to post their longest winning streak since January last year, with investors backing bullion over the past few days because of a slump in the dollar after the Federal Reserve’s cautious stance on the US economy and diminishing likelihood of an early rate increase. The dollar remains the main driving factor of gold price and traders will be looking very closely towards (Fed officials’) comments to gauge when and how rapid the rate hike will be.
As manufacturers we’ve observed that, while bullion sales may have waned, weak prices have spurred an increased in demand of precious metal for manufacturing into jewellery, semi-finished and/or final products. This anecdotal observation has been supported by a recent report from New York-based CPM Group, forecasting an increase of over 4% in 2015 of fabricated Gold products. Marking the second straight annual rise, and feeding my optimism of higher Gold and Silver prices. Demand is still out there, just that weâ€™re observing it in a different form.
In last weekâ€™s report I pointed out an opportunity in Platinum, â€œat US$1116, this is undervalued considering fundamentalsâ€ ? and suggested that buying with â€œa view that we see a repositioning in the market which will carry Platinum to US$1175-1180 resistance levels.â€ ? Todayâ€™s platinum price now resides around US$1150, so weâ€™re witnessing this correction unfold. If Gold continues its test of US$1200, then we should see our Platinum target met.

When Tuesday blues strike remember that every cloud has a silver lining. Read the latest report byÂ ?Kevin Morgan to find out OMF’s recommendations:
*Gold and Silver rebound on Federal Reserve *Try sell Gold at USD 1190 with a $15 stop OCO take profit at USD 1170 *Try sell silver at USD 17.05 stop at USD 17.50 take profit at SD 16.20
Apologies for the delay in our weekly report, but with so much riding on the Federal Reserveâ€™s Federal Open Market Committee (FOMC) report released this morning, itâ€™s more beneficial to analyse its impact.
Earlier this month a better than expected US jobs report fuelled speculation that the Fed would reveal a more hawkish stance in this morningâ€™s announcement. In reality many were wrong footed by a subdued assessment of the US economy, leaving the market to rethink the timing of any increase in US interest rates. The FOMC noted that â€œeconomic growth has moderated somewhatâ€ ? over the past month, which is a significant downgrade from the last statement wherein it said that activity rose â€œat a solid paceâ€ ?. They also indicated that when interest rates do rise, they will likely rise at a slower rate than previously expected. Compared to expectations, this is a strongly dovish statement, resulting in a scrabble to cover and adjust positions.
The most significant impact from the report was the sudden correction to the USD. The USD index (a basket of currencies against the US dollar) plummeting 5%, before settling 2.2% lower. Precious metals and commodities all benefiting, with Gold climbing back above US$1150 support to close near US$1170 (+1.6%), while Silver gained 2% to settle just shy of US$16 per ounce.
Looking ahead, Gold still has plenty of headwinds, so Iâ€™m not getting overly excited unless we break and hold US$1180 resistance. As per last weeks suggestion, I do own Gold Call options, allowing me to benefit from any sustained Gold rally. With Platinum at US$1116, this is undervalued considering fundamentals, so Iâ€™m suggesting to hold and buy more with a view that we see a re-positioning in the market which will carry Platinum to 1175-1180 resistance levels. (more on this next week).

Here are some tips for when you are reusing your clean scrap or customerâ€™s metal. Please comment if you have any tips you wish to share with us.
- Be Clean and Tidy: If you know whatâ€™s in your scrap it will make it much simpler to troubleshoot any issues that might arise later.
- The Periodic Table: You donâ€™t have to have a degree in chemistry, but do try and learn about how metals behave. Remember that if they are close to each other on the table, they may behave similarly.
- Precious Metals vs. Non-Precious Metals: Alloys usually contain non-precious metals which will affect their behaviour. High copper content such as reds and pinks can affect the crystal structure making the metals prone to cracking. As can nickel, or even silicon from casting scrap.
- Quenching: Quenching in hot water (or metho) can help when dealing with alloys containing non precious metals. This helps by making the cooling rate of the different metals more consistent.
- Fluxing/Gases: If your metal is questionable, an additional fluxing step is recommended to remove impurities. Likewise, if you see bubbles/flaring when melting it is worth cooling, then reheating the metal while stirring to try remove the gas. If the metal is still not acceptable after these steps we recommend that you refine and start again with fresh metal.
- Oxidising: When melting/pouring, use of a cover flame will help avoid oxidisation. If this is not done it can result in burning off of metal (silver especially) but also in the hardening of the outside layer which can later cause issues especially if worked in to the metal.
- Molds: This is purely a safety tip, but please make sure you heat your molds well before use.
