The African country of Uganda is in the limelight again, and this time it is literally shining gold. The country has recently announced the discovery of a deposit of 31 million tonnes of gold ore, with extractable pure gold estimated to gross 320,000 tonnes.
Over the last two years, aerial exploration was done across
the country, followed by geophysical and geochemical surveys and analyses,
Solomon Muyita, spokesperson for the Ministry of Energy and Mineral
Development, told Reuters. The government has expressed its intention to
attract big investors to develop the Sector hitherto dominated by small wildcat
miners.
We explain what the discovery entails for the global Gold
market.
What makes Gold valuable?
Gold is a bright, slightly reddish yellow, dense, soft,
malleable and ductile metal in its purest form. It is one of the least reactive
chemical elements and is solid under standard conditions. Gold is resistant to
corrosion and most acids and has unique properties distinct from other metals.
Another reason gold works well in terms of value is that
gold does not readily oxidize. Thus, it maintains a constant weight. Other
metals, such as iron rusts and copper, get oxidized. Here gold is rare, has a
fairly stable volume and doesn't rust away.
What are the typical uses of gold?
The prime characteristics of being corrosion-resistant and
easy -to -work renders gold highly desirable for various purposes, such as
decoration. The Industrial demand, especially in the electrical Sector for
gold, is mainly due to excellent thermal and electrical properties
Most of the gold fabricated today goes into the manufacture
of jewellery. Still, gold is also an essential industrial metal that performs
critical functions in computers, communications equipment, spacecraft, jet
aircraft engines, and a host of other products.
Besides, a significant amount is consumed in dentistry and
medicine. Continuing research has discovered new applications for gold as a
catalyst and in nanotechnology.
Is gold scarce?
Gold often occurs in free elemental (native) form, as
nuggets or grains, in rocks, veins, and alluvial deposits. However, gold is not
a rare metal. Still, it's difficult and expensive to find and extract the same
in large quantities - it is rarely found in concentrations that make extraction
economically viable.
Gold explorers conduct geological surveys to support a
profitable mining project targeting concentration levels that are 1,000 times
higher than normal. It can typically take between 10 and 20 years after a
deposit is discovered before a gold mine is ready to produce material that can
be refined into bullion.
How is gold mined?
Gold mine exploration is challenging and complex. It
requires significant time, financial resources and expertise in many
disciplines – e.g. geography, geology, chemistry and engineering.
The likelihood of a discovery leading to a mine being
developed is very low - less than 0.1 per cent of prospected sites will lead to
a productive mine. And only 10 per cent of global gold deposits contain
sufficient gold to justify further development.
The development of the mine is the next stage of the gold
mining process, which involves planning and construction of the mine and
associated infrastructure. It generally takes several years, although this
varies greatly depending on location.
The gold mining operation stage represents the productive
life of a gold mine, during which ore is extracted and processed into gold.
Processing gold involves transforming rock and ore into a metallic alloy of
substantial purity - known as doré - typically containing between 60-90 per
cent gold. Once the gold is purified, it is smelted and pressed into gold bars
to be sold in the market.
What is the status of global Gold Reserves?
According to Mineral Commodity Summaries, 2021 by the United
States Geological Survey (USGS), the estimated world reserves of gold were
about 53,000 tonnes of metal content.
The gold reserves are mainly located in Australia (10,000
tonnes), Russia (7500 tonnes), the USA (3000 tonnes), South Africa (2700
tonnes), Peru (2700 tonnes), Indonesia (2600 tonnes), and Brazil (2400 tonnes).
How is Global Gold supply ensured?
The total world gold supply comes from mining and recycling
above-ground gold stocks.
Mine production accounts for the largest part of gold supply
- 75 per cent each year. The world mine production of gold was estimated at
3,350 tonnes in 2019 compared to the 3,470 tonnes in the preceding year. The
top five leading gold-producing countries were China, Australia, Russia, USA
and Canada.
Currently, about 90 countries mine gold, of which there are
just seven major players. China has been the largest gold producer in the
world, accounting for around 11 per cent of total annual production. But no one
region dominates. The other major countries are Australia (10 per cent), Russia
(9 per cent), the USA (6 per cent), Canada (5 per cent), Ghana & Peru (4
per cent each) and Mexico & Indonesia (3 per cent each). India's share in
the global gold production is less than 0.05 per cent.
As it is virtually indestructible, nearly all of the gold
ever mined is theoretically still accessible in one form or another and
potentially available for recycling. The majority of recycled gold, about 90
per cent, is extracted from high-value gold jewellery and 10 per cent from
industrial gold.
From where demand for gold comes?
Gold is bought worldwide for multiple purposes – as a luxury
good, a component in high-end electronics, a safe-haven investment, or a
portfolio diversifier. It covers jewellery fabrication (~34 per cent),
technology and industrial purpose (~7 per cent), investments in financial
products like ETFs backed by gold and other physical gold investments (~42 per
cent) and those held by central banks (~17 per cent).
Gold demand is geographically diverse, but 72 per cent comes
from emerging markets, with China and India representing 50 per cent of all
demand. While China accounts for around 28 per cent of the global demand,
India's demand accounted for around 22 per cent.
However, as India has little domestic supply of gold,
imports primarily satisfy demand. The cost of these imports is partially
responsible for today's current account deficit (CAD). Gold supply in India is
primarily met through imports, with less than 1 per cent coming from local
mining and about 10 per cent from recycling.
So, how Uganda stumbled upon the vast gold reserves?
Over the last two years, the East African country
commissioned aerial exploration across the country, followed by geophysical and
geochemical surveys and analyses. The gold can be mined with immediate effect.
The government now looks forward to attracting gold miners and investors.
The move follows President Yoweri Museveni's government's
attempts to ramp up investment in mining to develop resources like copper, iron
ore, gold, cobalt, and phosphates.
Most of the deposits were discovered in Karamoja, a parched
sprawling area in the country's northeastern corner on the border with Kenya.
Large reserves were also found in the country's eastern, central, and western
regions. According to the Ugandan government, the value of 31 million tonnes of
gold ore stands at $12.8 trillion.
Are the numbers plausible?
As mentioned, the numbers put out by the Ugandan mining
ministry drew some scepticism. A great deal of gold ore is required to produce
a single gram of refined gold.
Typically, a high-quality underground gold mine will yield 8
to 10 grams of refined gold per metric ton of gold ore, according to the World
Gold Council (WGC), while a marginal quality mine generates 4 to 6 grams per
metric ton.
Suppose one settles on a rough average of 7 grams of refined
gold per metric ton of gold ore. This means Uganda's mines will generate about
217 metric tons of refined gold, a far cry from the 320,158 metric tons of
refined gold that the Ugandan Government told the country's new discovery could
produce Reuters. The addition of 217 metric tons would raise the world's "above-ground"
refined gold stock by only about one-tenth of one per cent.
How does Uganda aim to exploit the untapped reserves
commercially?
The Ugandan government has already licensed the Chinese firm
Wagagai Gold Mining Company to start production in the Busia district in
eastern Uganda.
A tweet posted by the Uganda Investment Authority read:
"Ground breaking ceremony of Busia's gold mine project, largest gold
deposit so far quantified in Uganda estimated @ 12.5 tonnes of mineable gold,
investor Wagagai's initial investment is USD 50 million, 3,000 direct
jobs."
The company recently obtained a gold production license in
March this year and has a 21-year lease to mine gold in the country. The
Chinese-run firm expects to mine and start refining around 5,000 kg of gold
daily in Busia by the end of the year.
What is the debate around gold refining in Uganda?
Gold mines produce rough gold, called doré, which is
typically about 80 per cent pure gold. This gold doré is then sent to a
refinery, where it is refined into gold of different forms and purity. The most
widely produced gold bars are the London Good Delivery bars. Refining gold
locally could enhance job creation and improve social service delivery to those
living close to where the mineral is extracted.
Ugandan President Yoweri Museveni has called for the local
refinement of the discovered gold, calling any external refinery criminal.
"It is criminal for anybody to argue for the continued exports of raw
materials in Africa when there is 90% more value in that product that you are
giving to the outsiders", he said.
As per reports, the Chinese firm has invested $200 million
in constructing a refining facility. The company began constructing its gold
refinery valued at USD200m in phases in the district in 2016.
