Is There Rhenium in Them Thar Hills?


Morning Miners!

It is 5:31 AM. Have a cup of joe and let's look for something other than gold and molybdenum in "them thar hills" to the north of town. Last month I promised to do a followup on one of earth's rarest elements, rhenium. What peaked the ole Colonel's interest was a recent statement by Kennecott project manager, Doug Stauffer, of their Bingham copper mine in Utah, "The rhenium market is a growing high-margin market and we're looking to become a stable and secure producer of that material." (Rhenium - Will the Sun Shine on One of Earth's Rarest Elements?, Eureka Miner's Market Report, 4/29/2010)

Bingham is primarily a copper mine but they boast good prospects for molybdenum and other metals such as rhenium that exist within their copper porphyry. Rhenium is a key ingredient in nickel-based super-alloys used in the components for jet engines. I wondered at the time whether there may be some other uses for this curious transition metal in the emerging alternative energy industry. As the 4/29 article suggests, the Chinese have demonstrated some research interest in rhenium to improve the light absorption properties of organic photovoltaic cells used to convert solar energy to electricity. At that time I wondered if a global expansion of solar farms that use large-scale organic solar arrays may provide another commercial use for rhenium.

When I get this far down on the "what if?" mineshaft, the Colonel likes to ask the experts for a sanity check. This boils down to two basic questions: (1)is there enough rhenium in our backyard to justify commercial exploitation and, (2) what shapes the real future demand for Miss Moly's kissing cousin? (rhenium is a transition metal kitty-corner to molybdenum on the periodic table of the elements)

I asked Tim Arnold, Mt. Hope Project Manager, for his thoughts on question #1. An early assay report on General Moly's Mt. Hope, one of the world’s largest and highest-grade deposits of undeveloped molybdenum (Mo), indicated that rhenium (Re) may exist in parts per million (PPM) concentrations. This may seem insignificant but rhenium has an average concentration of only 1 part per billion (PPB) in the Earth's crust. Along with gold (Au), rhenium belongs to the nine rarest elements on earth. Gold is about 4 times more abundant so PPMs of this stuff is nothing to ignore. This chart shows the relative abundance of Mo, Au and Re in relation to other metals on a logarithmic scale:


This was Tim's response to the Report,

"We very definitely will be looking at Rhenium. It is such a scarce element, that it is hard to identify as an 'ore', because the samples taken are typically in PPM or PPB. That is why we will be doing more investigation once we have a molybdenum concentrate. Rhenium floats along with the moly, so we will be able to see it there, and then extract if it makes sense."

I posed the second question to Dr. Jon Hykawy of Byron Capital Markets, a leading analyst on clean technologies/alternative energy and the metals they employ (see note 1 for a brief resume) We first met Dr. Hykawy in the March 22nd Report - A Third Tank on Our Hill? Lithium & Vanadium Update. He was less enthusiastic about the commercial use of rhenium in organic cells:

"...the [solar photovoltaic] technology used really dictates what other metals are required. Almost every organic cell design needs some form of metal dopant, but I have seen them requiring everything from rhenium to lead to really exotic stuff. I would put my money on something that used lead over something that used rhenium, just on a price basis."

However, Dr. Hykawy offered this valuable insight:

"But, I would also be pretty excited about rhenium anyway. It is refractory as all get out, and as more stringent regs come into effect for jet engines and their fuel efficiency and emissions, the only way to make these things work that much better is to run them at higher and higher temps, and alloys containing rhenium are a big part of that."

A consistent theme of this Report is the importance of strategic metals to the future of Northern Nevada and Eureka County. I think from the above responses we can add rhenium to our watch-list of important metals on our horizon, pardner.

By the by, COMEX gold broke $1220 this morning as concerns about European sovereign debt returned to the marketplace. Silver followed and is now in $19 country. I can collect my bet that the latter would occur before Memorial Day - Yee-ha!

Enough talk, let's walk the walk:

4-WD is ON - rough roads in the marketplace; the VIX or "fear index" is back in 30 territory; metals & miners are on shaky timber with benchmark FCX trading in the low $70s below its 200-day average of $75 (our new warning level), 10-year Treasurys are safely below 4% preserving a low-interest rate environment

The YELLOW light returns for Stable Markets with the VIX above the 30 level again (what's this?)

The GREEN light returns for Investor Confidence with the possibility of a >10% correction in the broader markets possible but less likely

The GREEN light remains turned on our Fuel Gauge with oil below $80 (although this may only be a brief respite)

A ORANGE light is ON for possible adverse regulation/legislation: Mine Safety Violations, Miner's claim fee, Miner taxation, Cortez Hills, mercury emissions &
General Moly Mt. Hope Water Rights


Otherwise, all lights are green on the Eureka Outlook Dashboard (upper right, what's this?)

NYMEX/COMEX: Oil is down $0.61 in early trading to $76.19 (June contract, most active); Gold is up $21.8 to $1222.6 (June contract, most active); Silver is up $0.563 to $19.115 (July contract); Copper is down $0.0545 to $3.1735 (July contract)

Western Molybdenum Oxide sits at $17.75, LME moly 3-month seller's contract sits at $18.14

The DOW is down 66.36 points to 10,718.78; the S&P 500 is down 8.82 to 1150.91. The miners are mixed:

Barrick (ABX) $45.91 up 4.55%

The Steels are down, (a "tell" for General Moly & Thompson Creek):

ArcelorMittal (MT) $35.69 down 3.54% - global steel producer
POSCO (PKX) $103.33 down 3.52% - South Korean integrated steel producer

The Eureka Miner's Grubstake Portfolio is is down 0.33% to $1,404,773.05 (what's this?).

Rhenium - Will the Sun Shine on One of Earth's Rarest Elements?



Morning Miners!

It is 6:16 AM. Grab a cup of Thor's java - I vote we take a break from the woes of Greece and Goldman Sachs; let's look down the road and see what may be shinning in our future instead. Yesterday a reader of the Report urged us look at what's happening with moly in Utah. Rio Tinto's Kennecott Utah Copper Corp plans to invest $340 million to build a molybdenum autoclave process (MAP) facility near their open pit Bingham Canyon mine southwest of Salt Lake City:

Kennecott to boost moly output with $340m autoclave facility (AMM, Tom Jennemann, 4/15/2010)

The Report carried an article on the molybdenum potential of this mine last September (Massive Moly Deposit Found in Utah, 9/30/2010). Molybdenum is a typical byproduct in the refining process of porphyry copper deposits such as Bingham. According to this article, Kennecott expects to produce moly at a rate of 60 million lbs a year by 2015. The MAP facility will process lower-grade molybdenum concentrate more efficiently than through a conventional roaster, leading to improved recovery rates. Kennecott project manager Doug Stauffer explains the process to AMM and Kelly Sanders, Kennecott president and chief executive officer, provided his view on the future of moly, "The outlook for molybdenum demand is very strong, driven by the rapid urbanization and industrialization of China and India. The production of molybdenum and gold make Kennecott one of the world's lowest cost producers of copper."

What caught the Colonel's eye was the expected recovery of rhenium - one of the rarest elements on earth. Rhenium is typically an ingredient in nickel-based superalloys used in the components for jet engines. By the 2015 time frame, Kennecott predicts a 9,000 lb annual production. Stauffer explains, "The rhenium market is a growing high-margin market and we're looking to become a stable and secure producer of that material."


A consistent theme of this Report is the importance of strategic metals to the future of Northern Nevada and more generally, as demonstrated by this case, the Great Basin. I don't yet know the rhenium potential in our county or state but I plan to do a little digging. Why? There may be another use for this important transition metal on the horizon, pardner.

A second theme of this Report is how electrified transportation and the emerging alternative energy industry may dramatically increase demand for certain metals like lithium, vanadium and silver (we'll close with a complete list of Eureka Miner articles on this exciting topic). Is there a role for rhenium?

The expansion of solar and wind farms is part of our national strategy to reduce dependence on foreign oil and improve energy security. One challenge in developing giant solar panels are the materials used in the many photovoltaic cells used to convert solar energy to electricity. Conventional solar cells are based on silicon, an inorganic semiconductor. Silicon has, however, the drawback of high production and processing costs and in some applications, the rigidity of the cell construction. An organic photovoltaic cell (OPVC) that uses organic polymers for light absorption and charge transport offers the advantage of low production costs in high volumes and increased structural flexibility. The main disadvantages of OPVCs are low efficiency, low stability and low strength compared to their inorganic cousins.


All this needs to be sorted out for large-scale solar applications, but rhenium may provide a way to improve the efficiency of the organic solar cell - a promising transition metal for improving optical absorption. The Chinese are working on such an approach:

Transition-metal complexes photosensitize organic solar cells (Wai Kin Chan, Department of Chemistry, The University of Hong Kong, 9/1/2009)

In fairness, this research is in the early stages and perhaps better approaches will be found with metals other than rhenium. The quantities of this rare element required for future solar cell production may also be small in comparison to the demand by jet engine manufacture. Today, I can't answer these questions but this Report is dedicated to running down any leads that may influence our mining future and prosperity in a positive way. Stay tuned buckaroos.
