This thread will talk about the huge issues facing consumers from a finance perspective. This is a bigger problem than availability of metal or the price being paid.
Exponential price rises are creating huge headaches for consumers - both in terms of price paid, availability of metal and in finance. Of these finance is probably the biggest issue.
Metal supply chains have multiple points: from metal to shapes to intermediate products to final products. For example for copper consumption in an A/C unit it goes from cathode to plate and wire rod, to tube and wire, to heat exchanger and copper flex. Then final product.
The intermediate manufacturers often work on a formula where copper costs are passed straight through to the next stage, with a margin for their work added. They need working capital to fund this.
With copper prices having doubled, the working capital requirement has doubled. This is against a fixed margin business: raising this additional bank finance is VERY difficult. As is sourcing additional credit insurance on their customers.
Lending banks are also being asked to take a lot more price risk as well, due to the increase in volatility and potential to be left holding the baby if / when copper prices crash.
Normally 90% finance is available to these types of business - but this is not available with copper at $10k. I am speaking with friends at businesses having to reduce volumes due to a lack of bank lines.
This is short term #copper demand destruction driven by financing considerations. Medium term though margins will necessarily increase to a level where profitability supports bigger lending lines. This drives consumer price inflation.
This also means that pent up metal demand is now hardwired into the supply chain.

#copper $MNO.v
So a quick thread on why VMS type copper deposits are so much more valuable than porphyries.
(I am talking in the generic here, and each project has its own specifics so please do not message me saying I am wrong about such and such project!)
VMS = Volcanogenic Massive Sulphide are “black smokers” emplaced on the sea floor and then moved to surface via tectonic activity. They are almost always polymetallic and contain copper, zinc, gold, silver, zinc and lead.
VMS’s are found around plate boundaries and usually occur in clusters – or “camps” – such as Flin Flon, Bathurst or Noranda. Tonnages typically range form a few million tonnes of ore to +100Mt. Copper equivalent grades are typically 1.5% ish.

#mining #copper #tin
I have been asked by several people now about how to evaluate the management team for a project and what to look for and what to avoid. This thread hopefully will provide some good pointers.
Truth Number One:
A mediocre project with good management is a better investment than a great project with mediocre management.
Truth Number Two:
There is no such thing as a bad project with good management: good people just don't get involved with bad projects.

“The world’s top copper producer Chile saw output of the red metal fall for the tenth consecutive month in March, government statistics agency INE said on Friday.
Copper output fell 1.3% in March, to 491,720 tonnes, the agency said.”
#copper
Chile also introducing new restrictions on movement and commerce following the Southern Hemisphere’s summer holidays. I expect their already bad Covid situation to get worse as they move into their Winter / European Summer.

As I understand it most mines have had essential workers only on site - very few contractors allowed in. This means essential specialist work and maintenance has not been kept up to date with operating and mining plans.

#zinc
The global zinc market is, give or take, 13 million tonnes. China is far and away the largest producer with over a third of mine production and smelter capacity. Supply growth in China is static though with new mines barely replacing old mine capacity.
#zinc
Zinc’s main use is as a anti-corrosion coating on steel in the construction and automotive industries. This is called galvanization. Other uses include alloy (brass mainly) die-casting precision components and as a fertiliser additive.
#zinc
Consumption growth is highly correlated to Global economic growth - 2.5x geared to growth above/below 2.5%. (i.e. zero consumption growth at 2.5%, but 5% consumption GDP growth of 4.5%.)

#tin
Tin is the 49th most abundant element within the Earth and has the chemical symbol Sn, which is derived from the Latin word “Stannum”. Crustal abundance is only 2 parts per million (“ppm”) compared with 75 ppm for zinc, 50 ppm for copper, and 14 ppm for lead.
#tin Tin mining dates back at least 4000 years to the Bronze Age, when tin was alloyed with copper to make bronze. Tin does not occur as the native element but must be extracted from oxide ores. Cassiterite (SnO2) is the only commercially important source of tin.
#tin Cassiterite is insoluble in water and erosional processes of deposits often results in placer deposits. Maybe 70% of all historic tin production has come from hydraulic mining or dredging of these alluvial type deposits, where grades as low as 0.015% tin can be economic.

#Tin
The secret to tin investment is easy if you focus on 3 things: mineralogy, mineralogy and mineralogy.
#tin Cassiterite is THE ONLY commercially valuable tin mineral. Most hard rock tin deposits contain some stannite (tin sulphide) and tin silicates. Look at the cassiterite grade, NOT tin grade.
#tin Alluvial deposits are more attractive generally than hard rock as they are 100% cassiterite. Cassiterite is dense with a specific gravity of 7 so water action concentrates it in placer type deposits.
