[PROJECT] pumpkin hollow copper mine project started in Q4, and the copper output is estimated to reach 23000 metal tons

Nevada copper Corp recently released the latest development of its 100% owned pumpkin hollow underground copper project. This time, the company reiterated that the project is expected to start in the fourth quarter of 2019, and said that the latest capital expenditure is estimated to be US $211 million. The copper reserves of this underground mine reach 24million tons, and the copper equivalent grade is 1.74%. It is estimated that in the next 13.5 years, the average annual output of copper will reach 50million pounds (about 22679.6 metal tons), the annual output of gold is 8000 ounces, and the annual output of silver is 150000 ounces. The preliminary feasibility study (PFS) of the project this year shows that the mineral resources determined and estimated by the project reach 553 million tons, with copper grade of 0.45%, gold grade of 0.07 g / ton and silver grade of 1.85 g / ton. This is equivalent to 5billion pounds of copper, 879000 ounces of gold and 29.78 million ounces of silver. (source: International derivatives think tank)

[International] Chile's copper output in August fell 0.4% year-on-year to 3.76 million tons

Cochilco, the national copper Commission of Chile, said on Monday that Chile's copper production in August fell 0.4% year-on-year to 3.76 million tons. Among them, the copper output of Codelco in August increased by 9.3% year-on-year to 154700 tons, but the total output in the first eight months of 2019 decreased by 8.4% year-on-year to 1.06 million tons.

The output of BHP Billiton Escondida copper mine in August fell by 8.5% year-on-year to 770800 tons. The Committee added that the output of the collahuasi copper mine controlled by Anglo American and Glencore increased by 0.5% year-on-year to 352500 tons in August.

Codelco pointed out that the decline in ore grade, bad weather around the northern mine and operational problems were the reasons for the decline in production. (source: Business Club)

[output] ICSG: in the first half of 2019, the world mine copper output fell by 1.4% year-on-year

According to the latest data of the international copper research group (ICSG), in the first half of 2019, the world mine copper production was 9.92 million tons, a year-on-year decrease of 1.4%, mainly due to the adverse weather in Chile and the stope transfer of two mines in Indonesia.

Regionally, in the first half of the year, the copper production of mines in Asia fell by 6%, that in Latin America fell by 1%, that in Europe fell by 3%, while that in North America increased by 2%, that in Oceania increased by 7%, and that in Africa remained the same.

In the first half of the year, the world refined copper production fell by 1%, and the apparent copper consumption fell by 1%.

ICSG estimated that in the first half of 2019, regardless of inventory, the supply and demand gap of refined copper in the world was 220000 tons. If the inventory factor is considered, the supply-demand gap is 190000 tons. (source: Xiben Shinkansen)

[industry] Analysis on the production status of 10000 ton copper mines in China

As the largest copper producer and consumer, China's demand for copper in copper concentrate has gradually increased to 4.989 million tons (2015), accounting for 33.1% of the global demand that year; However, China's copper resources are relatively scarce. The reserves of copper resources are only 30million tons, accounting for only 4.2% of the world. In 2015, the output of copper concentrate containing copper was 1.558 million tons, accounting for 10.2% of the global output, accounting for only 31.2% of the total domestic demand. The degree of external dependence is very high.

Due to the limitation of resource endowment, China's copper mines are characterized by relatively scattered distribution, low grade, great difficulty in mining and beneficiation, and most of them are small-scale mines, with few medium and large-scale mines. There are 2159 copper mining areas in China, distributed in 30 provinces and regions in China (as of the end of 2014, the Department of mineral resources reserves of the Ministry of land and resources made statistics). According to the statistical data of 2016, there are only 18 Copper Mines with copper concentrate production of more than 10000 tons in China. (source: Nanchu business network)

[observation] tight balance between supply and demand, price dilemma, when will "Dr. copper" break?

Since 2018, affected by macroeconomic pressure and trade disputes, copper prices have continued to be under pressure, but there has never been a sharp decline. In the third quarter of 2019, the fluctuation range of Shanghai copper was 45640-48390 yuan / ton, and the volatility has continued to decline since 2018. On the one hand, the central counter cyclical regulation has hedged the downward pressure on the economy to a certain extent. The demand growth rate of copper shows a slow downward trend, while the supply side has entered a period of low-speed growth in recent years, so copper is in a tight balance between supply and demand. On the other hand, the current copper price is in the historical equilibrium position, so the price is in a dilemma, and the volatility has decreased significantly. However, in the context of continuous supply tension, if the future counter cyclical force, domestic demand marginal improvement, then the copper price is also expected to usher in a phased rise.

On September 23, 2019, the solid waste Center announced the 12th batch of solid waste import approvals in 2019. This approval is the fourth batch of approvals involving waste copper released after the implementation of the restricted import system for six categories of waste on July 1. The amount of approvals continues to be significantly reduced compared with the first three batches. Up to now, the total physical quantity of waste copper issued in the first four batches of approvals is 484217 tons, which is about 387373 tons of metal according to the grade of 80%. In the second half of 2018, China imported 1.368 million physical tons of scrap copper, about 723000 metal tons, including 823000 physical tons of six types of scrap copper, about 605000 metal tons. The current approval volume is 330000 metal tons less than the actual total import volume in the second half of last year, and 220000 metal tons less than the import volume of six types of scrap copper in the second half of last year. The tightening of imported copper scrap is expected to superimpose the low copper price, and the price difference between refined copper and waste is significantly narrowed. The current use of copper scrap no longer has economic advantages, so some copper scrap consumption will be replaced by refined copper.

To sum up, copper is currently in a tight balance between supply and demand, and the price is in a dilemma. Therefore, the volatility has declined, and the cost performance of continuing to short the volatility is not high. It is suggested to consider long volatility in the medium and long term, and even try to long unilaterally when the price is low. (source: futures daily)


[battery think tank] the ultra-thin trend of lithium copper foil has been set

In the past third quarter, according to the information disclosed by enterprises, the sales growth of power battery market slowed down, but the demand for batteries in electric tools, electric bicycles, etc and other fields grew rapidly. Copper foil is one of the main materials of lithium batteries. Since the second half of last year, there has been excess low-end capacity in the industry, and the price has decreased year by year. Since June, due to the weakening market demand for power batteries, the competitive pressure in the lithium battery copper foil industry has further increased.

In addition, equipment and process are one of the main evaluation criteria for the competitiveness of lithium battery copper foil production enterprises. The gross profit rate per ton of 6 micron copper foil is much higher than that of 8 micron copper foil, which has become the focus of the layout of lithium battery copper foil production enterprises. In terms of application market, battery enterprises such as Ningde times have completed 6 μ M-based technology switching, and the ultra-thin trend of lithium copper foil is determined.
