The proponents of a long-standing copper project in north-west queensland are moving forward with their plan to operate an open-pit mine 75 kilometres north of cloncurry.
The proposed mine has a copper concentrate offtake agreement with glencore, which runs the mount isa mines mim copper smelter.
Mim committed to operate the smelter until 2022 and glencorex27s queensland metals said it was quotreviewing the business casequot for its future.
Glencore chief operating officer matt ox27neill said the company was in discussions with both state and federal governments about its future.
Mr ox27neill said high power costs, competition from international smelters and refineries,and declining ore grades at mount isa and cloncurry were among the key challenges facing the companyx27s metallurgical assets in queensland.

Mr. clausen continued, quotwith higher metal prices and lower costs, our objective is to build our cash position to allow for a rapid restart of the second stage of the mill expansion project, the installation of the third ball mill. the first stage of our 45,000 tonnes per day tpd mill expansion, the installation of the direct flotation reactors, was completed in early july. the company has also maintained spending on long lead time items associated with the ball mill 3 installation and we anticipate recommencing construction in late 2020 or early 2021.quot
As announced on march 10, 2020, the company implemented a revised operating plan for 2020 in reaction to the global covid-19 pandemic and the resulting lower copper price environment. the revised operating plan was focused on maintaining positive margins and cash flow. during the second quarter of 2020 the company continued to operate on this revised plan, with results exceeding expectations.
C1 cash cost per pound of copper produced, net of by-product credits, for q2 2020 was us1.48, as compared to us1.74 in q2 2019. the decrease in cost per pound in q2 2020 was the result of reduced mining costs and higher by-product credits 33.9 increase for the gold and silver produced in q2 2020 as compared to q2 2019. aisc per pound of copper produced for q2 2020 was us1.67, as compared to us1.85 in q2 2019. the low aisc includes 4.8 million in sustaining capital, lease and applicable administration expenditures in q2 2020 as compared to 2.7 million in q2 2019.
Aic per pound of copper produced for q2 2020 was us1.67 as compared to us2.35 for q2 2019. aic is the same as aisc for q2 2020 as there were no deferred stripping or low-grade stockpile mining costs incurred in q2 2020 as compared to 10.7 million of deferred stripping and 1.7 million of low-grade stockpile costs in q2 2019.
The significant decrease in c1, aisc, and aic recognized in q2 2020 as compared to past quarters was a result of the companys cost savings initiatives and operating efficiencies at the copper mountain mine, supplemented by an increase in precious metals prices and production for q2 2020.
Cost of sales in q2 2020 was 60.8 million as compared to 63.5 million for q2 2019. the reduction in cost of sales was primarily the result of the companys cost savings initiatives, which included utilizing less equipment and mining fewer tonnes. as a result, q2 2020 cost of sales did not include mining costs being allocated to the low-grade stockpile or to deferred stripping. this is compared to q2 2019 cost of sales which was net of 12.0 million of deferred stripping and 1.9 million low-grade stockpile costs.
The company reported net income of 31.9 million for q2 2020 as compared to net income of 2.5million for q2 2019. the variance in the higher net income for q2 2020, as compared to q2 2019, was a result of several items including
On adjusted basis, the company recorded a net loss of 1.5 million in q2 2020, compared to 0.01 million in q2 2019.
During q2 2020, the company completed the first stage of the 45,000 tpd mill expansion project with the installation of direct flotation reactors dfrs. the dfrs will increase the efficiency and the capacity of the current cleaner circuit, which is expected to increase copper concentrate grade from about 25 to 28, resulting in lower concentrate transportation, smelting and refining costs. the installation of the dfrs was completed on schedule and on budget. since the commissioning of the dfrs in early july, the project is achieving the targeted final concentrate grade.

The front end of europe8217s copper industry comprises three sectors miners, producers and semi-fabricators. it is made up of around 500 companies, has an estimated turnover of about 45 billion and employs around 50,000 people.
In addition, downstream sectors based on the added value achieved through the use of copper products e.g. energy utilities, electricians, automotive companies, electronic equipment manufacturers, plumbers and roofers employ several million people and represent a substantial part of the eus industrial base.
Minersextract naturally occurring ores and convert them into concentrates, made up of roughly one third copper, one third sulphur and one third iron silicate.
Copper mining also provides many valuable by-products that can be used in advanced material applications. for example, it is responsible for the production of almost 500,000 tonnes of cobalt, molybdenum, rhenium, selenium, tellurium and rare earth elements, in addition to volumes of silver, tungsten, gold, lead and zinc.
Producersreferred to as smelters and refinersconvert concentrates, imported intermediate materials and end of life scrap into copper metal. this process also generates important quantities of many other valuable metals, including gold and silver.
Semi-fabricators convert the metal produced by smelters and refiners and convert italong with clean scrapinto products, such as wire-rod, tubes, sheet and strip, for use further down the value chain.
Copper applications are diverse, covering sectors such as electrical engineering, automobiles, construction, machinery, shipbuilding, aircraft, precision instruments, watches and clocks. copper is a key material for innovation in areas such as renewable energy supplies, energy efficiency, sustainable buildings and transport systems.
The demand for copper has doubled in the last 25 years and is projected to go up further. a recent report from mckinsey global institute predicts that copper consumption will rise by 43 by 2035. this is likely to be partly driven by green technologies, such as solar and wind power and electric vehicles.
To meet future demand, we both need to continue to mine and improve recycling rates even further. europe8217s copper industry already leads the world in terms of recycling with nearly 50 of its copper demand through the recovery and recycling of value-chain offcuts, plus end-of-life products.
