Two new massive
mineral finds have been announced in the past days. In China, it is a gold deposit
and in Australia, it is an iron deposit.
Gold Deposit in Hunan Province Below Wangu Gold Field
The gold deposit
was found in deeper rocks below an existing gold mine. Estimates are that there
could be 1,100 tons as deep as 9,800 feet below the surface. The gold is expected
to be high-quality. The new find is below the Wangu gold field in Hunan
province. The find is considered to be a contributing factor to recently
rising gold prices.
China is the
world’s largest gold producer, responsible for 10% of global supply. According
to Reuters China “consumed 741.732 metric tons of gold in the first three
quarters of this year while output was 268.068 tons, meaning it has to rely on
imports to meet domestic demand.” Since China doesn’t currently meet its own
demand, this should help them since China is also the world’s largest gold
importer. It seems to me it should keep gold prices lower in the long run if or
as global supply is increased. Reuters also noted:
“Hunan Academy of Geology found more than 40 gold ore
veins at a depth of more than 2,000 meters in Pingjiang county, with a total of
300.2 tons of gold resources discovered in the core exploration area and a
highest grade of 138 grams per metric ton, Xinhua said.”
“The group forecast that there were more than 1,000 tons
of gold reserves at a depth of over 3,000 meters, according to Xinhua.”
“Gold reserves generally refer to the economically
extractable part of a resource.”
The ultimate worth
of the reserves is expected to be $82.9 billion. 138 grams of gold per metric
ton of ore is a very high-quality gold concentration. If the estimates are
correct, it could become the largest gold mine in the world, beating out a gold
mine in South Africa.
Largest Iron Deposit Ever Documented, Found in Hamersley
Province of Western Australia
This iron deposit
of an estimated 55 billion tons of ore is estimated to be valued at $5.9 billion
but it may be magnitudes more than that (notice that the gold deposit in China
is estimated to be 14 more valuable than this iron deposit, however, I do not
know the estimated costs to produce these resources). However, according to
Earth.com:
“Based on recent average iron ore prices of approximately
$105 per metric ton, the deposit’s total value could reach $5.775 trillion USD.
This staggering figure far surpasses the $5.9 billion initially reported and
highlights the significant economic implications of the find.”
According to Daily Galaxy:
“The discovery challenges existing theories on how iron
ore deposits are formed and how they evolved over billions of years. Until now,
it was believed that iron ore deposits in the Hamersley region were much older
— thought to be around 2.2 billion years old. However, researchers have now
concluded that these deposits are significantly younger, at about 1.4 billion
years old, indicating a much more dynamic history of iron ore formation.”
“The transformation of the iron ore, from its original
concentration of 30% iron to its current 60% iron content, has puzzled
scientists for decades. As Associate Professor Martin Danisík from Curtin
University explains, “The exact timeline of the change of these formations from
30% iron as they were originally, to more than 60% iron as they are today, was
not clear.”
A new model for
the discovery is being developed that links it to supercontinent cycles which
refer to the earth’s continents coalescing together in ‘Pangea’ events, then
drifting back apart. Supercontinent cycles are well documented in geological literature.
“As Earth’s continents drifted and collided over billions
of years, they influenced the distribution of minerals like iron ore. This
discovery suggests that the formation of massive iron deposits may have been
closely tied to the movement of supercontinents, with each cycle bringing about
conditions that were ideal for iron ore formation. By studying the exact
processes that occurred during these ancient supercontinent cycles, scientists
can now better predict how such deposits might form in other parts of the world.”
The new find may lead
to other new finds, especially in the local area. Australia already dominates in
iron ore production and this is likely to increase that domination.
