: Kanad Explorer mit 716 Millionen Tonnen Kupfererz
Das Gunnison -Projekt beherbergt zwei bisher nachgewiesene Erzkörper. Bei 184 Bohrungen mit einer Gesamtlänge von über 63.000 Metern auf den Lagerstätten "North Star" und "South Star" wurden 787 Millionen Tonnen Kupfererz gem. NI43-101 konform nachgewiesen.
Auf der 2,5 km langen, 700 m breiten und 200 m dicken "North-Star"-Lagerstätte wurden bisher 716 Millionen Tonnen Kupfererz mit Gehalten v. durchschnittlich 0,30 % reinen Kupferoxid gemessen. Die jüngsten Bohrergebnisse sind noch nicht vollständig ausgewertet und deuten auf durchschnittlich höhere Kupferwerte und höhere Ressourcen hin. Zwei Drittel des Kupfererzes sollen sich durch das In-Situ-Verfahren abbauen lassen.
Weiterhin verfügt das Unternehmen über ein sehr erfahrenes Management.
Northern Miner: Excelsior Steps Closer to Production
Article I found in the Northern Miner: Excelsior steps closer to production at Gunnison
Here is the text of the article without the pictures:
POSTED BY: SALMA TARIKH DECEMBER 6, 2016
Excelsior Mining (TSXV: MIN) shares have jumped 17% since the company tabled a positive feasibility study on the North Star deposit of its Gunnison copper project in southeastern Arizona.
The project, located in Cochise County, is a 2.5-hour drive southeast from Phoenix and 105 km southeast of Tucson. The Dec. 5 feasibility study, completed by Tucson-based M3 Engineering & Technology Corp., envisions North Star as a low-cost copper in-situ recovery (ISR) mine, with a 24-year mine life.
Excelsior?s CEO Stephen Twyerould says the feasibility study is the ?last major technical milestone? before the company receives final operating permits in 2017.
North Star?s initial production rate is 25 million lb. a year of copper cathode using the adjacent Johnson camp mine facilities, which Excelsior acquired last December from Nord Resources. Excelsior paid US$5.2 million on closing the agreement and has another US$3.2 million in payments due by the end of 2017.
Following initial production, the company intends to expand annual production to 75 million lb. in year four, and then to 125 million lb. in year seven. The final stage would require the construction of an acid plant. That should occur in year six and will significantly reduce the amount Excelsior spends on sulfuric acid.
The study advises staging the production profile so Excelsior could fund future expansions out of cash flow.
Getting the project up and running should cost US$46.9 million, including a 20% contingency. The initial capital includes US$14.6 million for the production wellfield, US$26.8 million for upgrades to the solvent extraction and electrowinning (SX-EW) plant and related infrastructure at the Johnson camp, and US$5.5 million for owner?s costs.
Total sustaining capital over the life of mine is US$742 million. That figure includes production wellfield expansion, SX-EW expansion, acid plant construction and water treatment facilities.
Production costs are relatively low, with direct operating cash costs of US65¢ per lb. and all-in costs (life of mine capital plus operating costs) of US$1.23 per lb. copper. This is partly because North Star contains oxidized copper, making it amenable to ISR mining.
Excelsior explains ISR mining consists of drilling boreholes (injection and recovery wells) into the copper orebody. It then pumps a weak acid solution into the injection wells to dissolve the copper in the rocks. Subsequently, it retrieves the copper-rich solution from the recovery wells and pumps it to the SX-EW plant to produce copper cathodes.
Other ISR copper projects and mines in Arizona include Taseko Mines? (TSX: TKO; NYSE-MKT: TGB) Florence, where phase 1 production should start pending receipt of final permits; Capstone Mining?s (TSX: CS) producing Pinto Valley mine; and BHP?s (NYSE:BHP; LON: BLT) past-producing San Manuel mine, which ran for 14 years.
The Gunnison project has strong economics based on an initial production rate of 25 million lb. per year. The base-case scenario generates a post-tax net present value (NPV) of US$807 million, at a 7.5% discount rate, and an internal rate of return (IRR) of 40%. Payback for the initial capital is a little over 2 years. The scenario uses a copper price of US$2.75 per lb., total copper recovery of 48%, and considers full annual production of 125 million lb. in year seven.
The company has also considered economics for the project without building an acid plant. Under the alternative scenario, initial capital remains the same at US$46.9 million. Total sustaining capital over the life of the mine drops to US$661 million. However, all-in costs increase 25% to US$1.50 per lb., as it is more expensive to buy sulfuric acid than to produce it on site. In the ?no-acid plant? scenario, the post-tax NPV is US$691 million, at a 7.5% discount, with an IRR of 41%.
?We have always been attracted to the scenario where we build our own acid plant because this dramatically improves our overall economics,? JJ Jennex, the company?s vice-president of corporate affairs, writes in an email.
?The Union Pacific Railway runs through our property; our plan is to bring in elemental sulfur from the West Coast and then create our own acid on site,? Jennex explains. The company will review building the acid plant (planned for year six) once commercial production begins.
According to its development timeline, Excelsior anticipates receiving the final operating permits by mid-2017. It aims to start stage one construction in the third quarter of 2017, with commercial production anticipated in the second quarter of 2018.
With its latest financing, Excelsior says it has enough funds to take Gunnison to a construction decision.
In late November, Excelsior closed a US$14 million financing with private equity fund Greenstone Resources. It issued 28.8 million shares at US77¢ for US$10 million and a 1% gross revenue royalty on the Gunnison project and Johnson camp mine for proceeds of US$4 million. Greenstone now owns 84.4 million Excelsior shares or 50.4% of the company and a 3% gross revenue royalty on Gunnison and the Johnson camp mine.
?The team at Greenstone is the epitome of smart money,? Jennex contends. ?They have done extensive due diligence on our project and this has resulted in a total investment into Excelsior of US$36 million to date. This is a major endorsement for the quality of the Gunnison copper project and the ability of our management team to execute.?
Excelsior?s next financing milestone would be arranging the project?s initial capital, which it has been working on for sometime, Jennex says.
The North Star deposit contains a measured and indicated resource of 792 million tonnes grading 0.29% copper for 4.9 billion lb. copper. This includes probable reserves of 709 million tonnes million at 0.29% copper for 4.5 billion lb.
On Dec. 6, Excelsior shares gained 17% over two trading sessions to close at 62¢.
