Mining Process
The process begins with the exploration of specific geological areas that may be conducive to the formation of gold.
A mining company needs to locate an accessible area that contains gold in 2,000 to 3,000 parts per billion (ppb) to be profitable.
Thus, geological, geophysical and geochemical data is collected to determine the probability of a deposit. If sufficient
data is acceptable then test drill holes are sunk in a predefined area to take sub-surface samples, which are then sent to
a laboratory to determine the eveidence of any gold ore. Gold- bearing material can be classified as:
Placers
Free milling ores
Oxidized ores
Silver-rich ores
Iron sulphides
Arsenic sulphides
Copper sulphides
Antimony sulphides
Tellurides
Carbonaceous
Mines are either open pit surface excavation or deep shaft.
In surface excavation, large drilling rigs bore a pattern of holes into the rock, which is then filled with an explosive
compound. The compound is then ignited in order to fragment the rock into a size that can be loaded and hauled away.
Large masses of rock are excavated, crushed and processed to remove and separate gold particles from the crushed
rock. Some mines specifically excavate for gold or gold is found as a by-product during the excavation for other minerals such as
copper or silver. It is very rare to actually locate gold nuggets that are of 0.900 in fineness (parts per thousand).
Cyanidation is the method of extracting gold and silver contained in ores or concentrates by dissolving them in a weak
solution of potassium or sodium cyanide.
South Africa leads all nations in
total gold production. The next largest production is from the United States (Nevada, Alaska, California and Utah),
Canada and then Australia. Other major producing nations include Russia, China, Indonesia, Peru, Uzbekistan and Papua New Guinea.

Gold Refining
Mines will perform some preliminary refining in order to produce ingots that can be transported to a professional
Assayer and refiner. These semi-refined ingots are known as Doré, and contain gold, silver and other trace
minerals.
Further refining is conducted in order to remove trace minerals. The refined gold must be assayed (independently
evaluated) to determine that the purity of the gold is of a suitable quality to be termed "good delivery".
The Italian-speaking region of southern Switzerland (Ticino) is one of the most well know areas for companies
performing assaying and the final refining of unrefined gold. The Central Office for Precious Metals Control, Federal Customs
Administration, maintains oversight of the industry in Switzerland. In Switzerland, precious metals articles must bear the
mark for a standard of fineness and a responsibility mark (assigned to each company in the industry) registered at the
Central Office for Precious Metals Control. Some of the local companies include, Argor-Heraeus, PAMP (Produits Artistiques de Métaux Précieux;
MKS Finance), Valcambi SA.
Bars must be at least 99.5% (Purity is usually expressed in parts per thousand as 0.995, 99.99, 999.9 or 0.999; it is very
difficult to refine out the last few impurities thus gold is never expressed in 100% terms) pure gold and weigh between
350 and 430 troy ounces to qualify as "London good delivery bar" in most international transactions.
The color of the gold bars will indicate the age of the bar and the impurities in the bar associated with the
proficiency level of smelting during the era that the gold was produced:
A reddish tinge indicates the presence of copper, which reflects bars produced from gold sources of melted coins and jewelry
and indicates older bars.
Butter yellow colored bars indicate bars that were produced by up-to-date smelters and from gold sources of below ground ore.
A white tinge to the gold bars indicates the presence of silver and platinum from older smelters and gold sources of below ground ore.
A greenish tinge indicates the presence of iron.
An unusual form of gold has a black tinge, which indicates the presence of bismuth.
Bars occasionally become dented due to handing (especially older bars that have been physically shipped several
times) however this does not detract from the value of the bar. Similarly, bars will sometimes appear to have notches
on the edge however these are chips removed for assay purposes and does not detract from the value of the bar.
Every bar will have the stamp indicating the smelter where the gold was refined as well as to where it was cast.
Additional identification marks will identify its purity and "melt" (how many bars were produced in that specific pouring;
If there is insufficient molten gold left at the end of the pouring to produce a single minimum 350 troy ounce bar then a series of smaller weight bars are produced as
molten gold from one melt is prohibited from being added to a successive melt).
A Certified Stock is physical gold that has been inspected and found to be of a quality deliverable against
futures contracts, stored at the delivery points and designated as regular or acceptable for delivery by the
commodity exchange
The main bar weight traded in Europe is a Kilo Bar, which has several different weights depending on
the assayed fineness of the gold:
0.995 fine gold kilo Bar comprises 32.1507 troy ounces
0.999 fine gold kilo Bar comprises 32.119 troy ounces
0.9999 fine gold kilo Bar comprises 32.148 troy ounces
A troy ounce is 31.1048079 grams and an avoirdupois ounce is 28.35 grams.
A troy ounce contains 480 grains and an avoirdúpois ounce contains 437.5 grains.
A standard international London Good Delivery 400 troy ounce bar weighs 438.8 avoirdupois ounces or
27.4 avoirdúpois pounds, approximate dimensions are 7 x 3-5/8 x 1-3/4 inches (since 1986, most 400 troy ounce bars
have been cast trapezoidal, and have either rounded corners or sharp corners), and based on the statutory price of USD$42.2222 per ounce
the value of a 400 troy ounce bar is $USD16,888.00
In the Far East gold is weighed in Taels (one tael equals 1.203 troy ounces), and the unit of trading is 100 taels
(123.04 ounces) which is usually quoted in Hong Kong dollars.
On the Indian subcontinent gold is weighed in Ten Tola bars (10 Tola = 3.75 ounces;
One tola equals .375 ounces or 11.1 grammes of 0.999 fineness).
There is a spot (cash) price for gold and a futures contract price for gold.
The price of gold was allowed to float in 1968. The price of gold is quoted in terms of troy ounces (one troy ounce
equals 31.1 grams). The statutory rate of a troy ounce of gold is $42.2222.

London Fixing
London Bullion Market Association - London Gold Fixing (10:30 AM and 3:00 PM Local London Time)
Every day at 10:30 a.m. and 3:00 p.m. local London time, the five bullion trading houses "fix" the price of gold
which becomes the benchmark for the entire gold market. At the start of each fixing, the Chairman announces an opening
price to the other 4 members who relay this price to their customers. The reason why London endures in this role is the presence of the Bank
of England which has a long history of direct dealing and marketing of gold into international markets on the behalf of
customer countries (the U.S. Federal Reserve Bank does not do this).
The five fixing market makers are Barclays Capital, Bank of Nova Scotia-Scotia Mocatta, Deutsche
Bank AG London, HSBC Bank, and Société Générale
The international market is also known as the "loco London market" due to the fact that gold is quoted for
delivery in London.
Contango: near futures prices exceed spot prices; the premium paid for futures over spot prices.
Gold Lease Rate: Libor minus the contango.
After being prohibited for several decades, on December 31, 1974, it
again became legal for U.S. citizens to own gold. Gold is used as an investment or inflation hedge by individuals,
companies, financial institutions, national treasuries and investment funds.
Gold is either purchased on an exchange (cleared contract) or OTC between a bank / broker / client.
Bullion trade / transactions require that parties utilize the 1997 ISDA Bullion Definitions and the 1993 ISDA Commodity
Definitions, as amended by the 2000 Supplement to the 1993 ISDA Commodity Definitions documentation.
Gold Usage
The largest usage of gold is in jewelry fabrication (approximately 80% of annual world production) and
consumption (India, United states, European Union, China, Saudi Arabia, Eqypt, Turkey, Italy). The
balance of gold is used as a storage of value, and as a component in manufacturing electronics, telecommunications
equipment, laser and optical equipment, aviation, and medical / health.
In India (and in Indian communities around the world), those who participate in the Hindu festivals of Dhanteras and
Diwali have traditionally purchased gold jewelry as part of the festival observance (occurs in the late Fall / October).
Weight / Fineness
Both the troy system and avoirdúpois system are British standards of measurement. Avoirdúpois is derived from the
French term "avoir du pois", or goods of weight, and the troy system takes its name from a city in France where it
originated (Tries).

Gold Loan:
Instead of buying gold, a jeweler will borrow gold for the duration of the fabrication process. Only when the
jeweler sells the finished product at a price related to the spot rate (and the value added) at that time will the jeweler
actually buy gold from the bullion trader. Jewelers thus simultaneously hedge their price risk and finance their stock at
an interest rate below normal borrowing costs.
An exploration company finds gold and needs to borrow to set up a mine. Instead of borrowing from a bank, the
company borrows gold (at a lower interest carrying rate). It sells that gold in the spot market and uses the cash to set
up the mine. It will borrow only what it takes to set up the mine and based on how much ounces/tonnage it may extract. As
the mine extracts the gold from the ground it pays back the borrowed gold.
Lease rate is determined for borrowing the gold, which includes and interest rate (360-day basis) and carrying charges,
which are costs incurred in warehousing the physical commodity such as insurance and storage.
Central Bank Holdings (Official Gold Reserves)
The largest offical gold reserves (above ground) include:
United States (8,133.5 metric tons)
Germany (3,408.3 metric tons)
International Monetary Fund (3,217.3 metric tons)
Italy (2,451.8 metric tons)
France (2,445.1 metric tons)
People's Republic of China (1,054.0 metric tons)
Switzerland (1,040.1 metric tons)
Japan (765.2 metric tons)
Netherlands (612.5 metric tons)
Rusia (568.4 metric tons)
European Central Bank (501.4 metric tons)
Source: World Gold Council; September 2009
The combined holdings of these parties account for approximately 24,197.5 metric tons / 81.7% of total (above ground)
gold reserves (29,633.9 metric tons) at September 30, 2009. In November 2009, India purchased 200 metric tons from the IMF.
The Central Bank Gold Agreement of 1999 (renewed March 2004) requires that the 15 largest government and supranational
gold owners restrict their sales into the market at a pace that would not cause substantial disruption of the price (presently
a combined maximum of 500 tons per annum for the next five years).
In the United States, the bulk of United States' gold reserves is stored under security at the Fort Knox Bullion
Depository. The balance of any official United States' gold reserves are held in the Philadelphia Mint, the Denver Mint,
the West Point Bullion Depository and the San Francisco Assay Office. The Federal Reserve Bank of New York also has an
extensive gold storage vault, however this is primarily allocated storage for second parties and not U.S. gold
reserves. The main vault of the New York Federal Reserve opened September 1924, and the Fed does not charge for the
storage service but does charge a nominal handling fee for shipping gold in / out of the vault.
