nomad acquires royalty on producing caserones copper mine in chile | kitco news

(Kitco News) - Nomad Royalty (TSX: NSR) (OTCQX: NSRXF) announced Thursday that it has entered into an agreement to acquire an effective 0.28% net smelter return royalty on the producing Caserones copper mine located in the Atacama region of Chile for a cash consideration of US$23 million as well as the issuance of two million common share purchase warrants of the company.

The Caserones mine is owned and operated by Minera Lumina Copper Chile, which is indirectly owned by JX Nippon Mining & Metals Corporation. The mine consists of an open pit mining operation, with a plant to produce copper and molybdenum concentrates from primary sulfides, and a solvent extraction and electro winning plant (SX-EW) to produce copper cathodes with oxide ore processing, mixed and secondary sulfides.

In 2019, the Caserones mine produced 146kt Cu and 2,778t of Mo with expected life of mine average annual payable production of ~148kt Cu Eq. Nomad noted that the mine has a long reserve life and significant exploration potential, located on a large land package of ~17,000 hectares with potential for future expansions.

CEO Vincent Metcalfe commented, "The Caserones royalty provides Nomad with immediate cash flow over a very long mine life from Chile, a tier 1 mining jurisdiction. This transaction highlights Nomad's unique positioning within the royalty space in terms of its financial capacity to acquire high quality royalties and is consistent with Nomad's strategy of building a diversified portfolio of high-quality cash flowing royalties and streams."

Nomad Royalty is a gold & silver royalty company that purchases rights to a percentage of the gold or silver produced from a mine, for the life of the mine. Nomad owns a portfolio of 14 royalty, and stream, assets, of which 7 are on currently producing mines.

the worlds top 10 highest-grade copper mines

the worlds top 10 highest-grade copper mines

Grade is king. This is very true, especially in todays challenging mineral commodities market conditions. The grade of metal in ore is usually directly related to the ability of a particular mine to make money and be profitable.

All things being equal, a higher grade generally means lower production costs per ounce/pound/ton, making high-grade ore deposits a crucial consideration for mining investors. Mines that can provide good returns in any market environment are the best of breed.

Why have only reserves been taken into account? This is because a mineral reserve is the part of the mineral resource that has demonstrated economic viability in current market conditions. Therefore, ore reserves are much less speculative than ore resources and relatively precisely reflect changes in the economic wellbeing of mines.

The following analysis covers those currently active copper mining operations throughout the world that are separate reporting units and which have most recent reserves figures, calculated according to international standards and disclosed by the owners/operators after December 31, 2014.

For a more accurate comparison, copper operations have been split into underground and open-pit, since these mining methods utilize different techniques and equipment. In this research, the focus is on ore grade in reserves while putting aside other crucial parameters like ore tonnage and volume of metal contained in ore.

olympic dam copper-uranium mine, adelaide, australia - mining technology | mining news and views updated daily

olympic dam copper-uranium mine, adelaide, australia - mining technology | mining news and views updated daily

The Olympic Dam is a huge mining centre located in South Australia, 560km north-west of Adelaide. Home to a major oxide copper gold deposit producing copper, uranium, gold and silver, the site hosts an underground mine and an integrated metallurgical processing plant.

The project was opened in 1988 by WMC Resources, after discovering the large deposit in 1975. It was later expanded under an A$1.9 million programme, raising its capacity to 200,000tpa of copper and 4,300tpa of uranium, plus gold and silver.

In 2007 BHP Billiton announced that it would undertake an expansion of the Olympic Dam mine. This plan was then shelved in August 2012 due to tough economic conditions and subdued commodity prices, a decision which led Australias Federal Resources Minister Martin Ferguson to declare that the nations mining boom is over.

The South Australian government gave BHP until October 2016 to proceed with its expansion plans, after intially demanding the company to begin work immediately or be forced to restart the approval process.

The initial plan was to increase the mines annual production to 70Mt, a seven-fold increase if the expansion proceeds. Copper production would have grown from approximately 180,000tpa to approximately 750,000tpa.

This would include 500,000oz of gold, 500,000t of copper and 15,000t of yellowcake. Existing average gold production is 80,000oz pa. The additional proven reserves of uranium now make Olympic Dam one of the most promising uranium mines in the world.

In May 2009 BHP announced a draft Environmental Impact Statement (EIS) for government approval of its expansion plan. The Supplementary Environmental Impact Statement (SEIS) was submitted to the Australian, South Australian and Northern Territory Governments for review in December 2010. The final SEIS was released to public in May 2011 and approvals from the South Australian Government and the Commonwealth were received in October 2011.

Mineralisation consists of medium-grained chalcopyrite, bornite and chalcocite, fine-grained disseminated pitchblende, gold, silver and rare earth minerals that occur in a magnetic hydrothermal breccia complex beneath 350m of overburden. The ore occurs in distinct zones that determine the mine access and layout.

Proven reserves at the Olympic Dam mine as of June 2011 stand at 146Mt graded at 1.98% Cu, 0.58kg/t U3O8, 0.69g/t Au and 4.01g/t Ag. Probable reserves are estimated to be 406Mt graded at 1.79% Cu, 0.57kg/t U3O8, 0.78g/t Au and 3.19g/t Ag.

Measured resources at the mine as of June 2011 are estimated at 1,408Mt graded at 1.08% Cu, 0.32kg/t U3O8, 0.34g/t Au and 2.07g/t Ag. Indicated resources stand at 4,571Mt graded at 0.88% Cu, 0.28kg/t U3O8, 0.34g/t Au and 1.56g/t Ag.

The current scope and logistical demands of the mine will be increased by a few orders of magnitude once the expansion gets into full swing. The mine will gradually be transformed from an underground operation to open pit.

Three vertical shafts and a decline access the orebody, which is worked using a variation of sublevel open stoping. Each stope may contain 300,000t of ore. Drill drives are driven on the stope centre line and blastholes drilled in vertical rings. These are charged with ANFO and detonated with shock tube detonators.

The drilling fleet comprises Atlas Copco and Tamrock production rigs, with development being carried out using two Tamrock (now Sandvik) jumbos. Atlas Copco has supplied two modified Simba H4356S production drilling rigs.

Stopes are backfilled with cemented aggregate of crushed mullock (waste rock), deslimed mill tailings, cement and pulverised fuel ash (PFA). Automation has done much to reduce production costs at Olympic Dam. Innovations include the automated underground haulage system and the smart loader, a robotics-driven, decision-making underground ore carrier.

Processing facilities consist of a copper concentrator, hydrometallurgical plant, copper smelter, sulphuric acid plant, copper and gold/silver refineries. Recent expansions included a Svedala autogenous mill, additions to the flotation sections, two counter-current decantation thickeners, an electric slag-cleaning furnace, a new anode furnace gas-cleaning plant and additional electro-refining cells.

Wastes generated during electro-refining are treated to recover gold and silver. After treatment by flotation, the finely-crushed ore is leached with sulphuric acid to dissolve uranium and any remaining copper. The leach liquor is processed in the solvent extraction plant to separate the residual copper and uranium streams. Copper is recovered by electrowinning and uranium converted to yellowcake and calcined uranium oxide.

Installation of two pulsed columns increased uranium recovery from solution from 90% to about 97%. These columns use an air pulse to mix the acidic and organic solutions, providing better contact for the chemical reaction involved in transferring the uranium from one to the other.

Copper cathode sheets are transported by truck within Australia and to Port Adelaide for export. All uranium oxide produced at Olympic Dam is exported. The gold plant became fully operational in 2000. A fire in 2002 at the solvent extraction / electrowinning plant cost over A$300m to repair, while WMC also spent A$127m on renovating the copper smelter during 2003.

At the end of October 2008, BHP Billiton announced that it expects to complete the first of the mines five-stage expansion by 2013, boosting annual production capacity to 200,000t of copper, 4,500t of uranium and 120,000oz of gold. The first phase of the Olympic Dam Project (ODP1) entered into feasibility study phase in March 2011. Construction is expectedly to begin upon approval from the BHP Board in mid-2012.

The expansion will be followed by a staged development of an open pit, with an eventual target annual output of 750,000t of copper, 19,000t of uranium and 800,000oz of gold. The company also said it is looking at shipping copper concentrate directly to smelters in China, which will cut the cost of producing cathodes at the mine.

Olympic Dam maintains storage facilities for all waste products. The plant has been designed so that any spillage of ore, concentrate or process slurries can readily be returned to the process circuit. The plant also includes comprehensive air pollution control equipment and both air emissions and noise are monitored. Extensive radiation monitoring of personnel and the environment is ongoing.
