Antwort auf Beitrag Nr.: 58.297.904 von bigyawn am 25.07.18 13:02:41Sehr stark die Aktie und das gegen den Trend von Gold. Eigentlich verhält sich die Aktie von McEwen eher andersrum...wenn Gold steigt fällt die Aktie gern.
ORIGINAL: McEwen Mining Black Fox Exploration News
2018-07-25 06:30 ET - News Release
TORONTO, July 25, 2018 (GLOBE NEWSWIRE) -- McEwen Mining Inc. (NYSE:MUX) (TSX:MUX) reports additional encouraging exploration results from its ongoing $15 million exploration program at the Black Fox Complex near Timmins, Ontario, Canada.
McEwen’s 2018 exploration goals are to grow known deposits and make new discoveries to contribute to near-term gold production. During Q2 a total of 129,000 ft (39,300 meters (m)) of surface exploration drilling was completed at Black Fox Complex, for a year-to-date total of 220,000 ft (66,900 m).
“Our drilling continues to deliver very encouraging results, particularly from the three project areas highlighted in this release: Stock East, Froome and Gibson. Continued drilling success reinforces our view about the strong exploration potential of both the Black Fox and Stock properties,” stated Sylvain Guerard, Senior Vice-President Exploration.
Three of our exploration targets are covered in this release: Stock East, Froome and Gibson. Underground delineation drilling intercepts from Black Fox are also included, along with a revised Black Fox Mine resource estimate, which eliminates the Inferred resource category and increases the Indicated ounces and grade.
Stock East
The Stock Mine property covers a 4 mile (6.5 km) section of the Destor-Porcupine fault, and produced 137,000 gold ounces at a grade of 5.5 g/t between 1989 and 2005. Our winter drilling program was designed to follow-up on historical intersections and geophysical targets; it returned better than expected results at the Stock East target and prompted an expanded 66,000 ft (20,000 m) drilling program beginning in early June. Three drill rigs are currently active and will infill the Stock East target, test the depth extension of the Stock Mine below 500 m, and attempt to join mineralization at Stock East with the historical Stock Mine over a 2,000 m long trend (see Figure 1).
Stock East has a strike length of approximately 500 m and extends vertically from surface to a depth of at least 450 m. Its proximity to our mill facility makes Stock’s potential for an open-pittable deposit a particularly attractive target.

Froome
The Froome deposit is located 2,800 ft (850 m) to the West of the Black Fox open pit. It was discovered in 2014 and has a current Indicated resource of 159,000 gold ounces at a grade of 5.26 g/t.
Drilling at Froome during Q2 has identified a mineralized structure in the footwall, approximately 150 m North of the Main Froome Deposit (see Figure 2). The gold-bearing trend hosts clusters of positive drill intersections at Froome Northwest, North and Southeast that may lead to the definition of additional zones of mineralization proximal to the Froome Deposit. In addition, new drill intersections below the Froome Deposit suggest some incremental resource expansion potential. The potential to develop underground access to the Froome Deposit through mineralization in the footwall could provide a major enhancement to the project’s economics and will be evaluated once drilling to better define the zones is complete.
Footwall drilling highlights include the following intersections:
19.42 g/t gold over 2.5 m, including 52.7 g/t gold over 0.83 m at the Footwall NW area;
7.97 g/t gold over 5.99 m at the Footwall North area; and
7.91 g/t gold over 3.12 m, including 13.9 g/t gold over 1.56 m at the Footwall SE area.
Drilling down-dip of the Froome Deposit encountered 4.04 g/t gold over 7 m, suggesting the mineralization continues at depth. Drilling at Froome will continue in Q3 to follow up on these results.

Gibson
The Gibson exploration target area is adjacent the Grey Fox Deposit, where Indicated resources of 465,000 gold ounces at a grade of 6.64 g/t, and Inferred resources of 100,000 gold ounces at 6.83 g/t are currently defined.
The present dimensions of the Gibson Zone mineralization are approximately 100 m in length along strike and 400 m depth from near surface. Additional drilling is underway to better define the extent and orientation of the mineralization.
Hole 18GF-1079 returned 3.11 g/t gold over 34 m (core length), including 10.81 g/t gold over 6 m, from a new style of breccia mineralization identified at the Gibson area. This new intersection suggests the potential for extension of the mineralization to a 500 m depth below surface. Drilling will continue in Q3 to further assess the potential depth extension.

Black Fox Underground
During Q2 a significant portion of the underground drilling was dedicated to confirming and expanding known mineralized trends that are located close to current workings and that could be brought into production quickly. Definition drilling to the east of 560 Central Zone (CZ) has extended the east sill nearly 30 m. Drill intercepts have recently been confirmed with high grade chip samples that were taken across development faces, including: 27.65 g/t gold over 3.4 m and 90.22 g/t gold over 3.3 m.

QUALIFIED PERSON
Technical information pertaining to geology and exploration contained in this news release has been prepared under the supervision of Ken Tylee, P.Geo. Mr. Tylee is a "qualified person" within the meaning of NI 43-101.
The mineral resource estimates were prepared by Dr. Aleksandr Mitrofanov, P Geo, who is a "qualified person" within the meaning of National Instrument 43-101 (“NI 43-101”). Dr. Mitrofanov is an employee of SRK Consulting, (Canada) Ltd and is considered to be "independent" of McEwen for the purposes of NI 43-101.
TECHNICAL INFORMATION
Black Fox Complex drilling was conducted by Forage Asinii Drilling, Boart-Longyear, Major Drilling, NPLH and Norex Drilling and supervised by McEwen’s Geology Department. All exploration drill core samples at the Black Fox Complex were submitted as 1/2 core. Analyses reported herein were performed by the independent laboratories: ALS Laboratories, which is ISO 9001/IEC17025 certified, Activation Labs, which is ISO 9001/IEC17025 certified, and SGS Canada Laboratories, which is ISO9001/IEC17025 certified. Samples from definition and select delineation drilling, and development sampling completed within the Black Fox mine are assayed at McEwen's onsite laboratory. McEwen’s quality control program includes systematic insertion of blanks, standard reference material and duplicates to ensure laboratory accuracy.
To determine the lengths of significant mineralized intervals, the following composite criteria was established: a minimum reportable interval length of 3 m was determined by establishing a cut-off grade of 3g/t Au for underground (1 g/t Au for near surface). A consecutive maximum length of 3 m of internal waste, including sub cut-off grade material, is allowed and incorporated into the reported composites. Where an interval of less than 3 m is considered, if the grade x length calculation is greater than 9 (3 for surface), it may be reported. There is no top cutting or capping of assays.

TORONTO, July 25, 2018 (GLOBE NEWSWIRE) -- McEwen Mining Inc. (NYSE:MUX) (TSX:MUX) reports additional encouraging exploration results from its ongoing $15 million exploration program at the Black Fox Complex near Timmins, Ontario, Canada.
McEwen’s 2018 exploration goals are to grow known deposits and make new discoveries to contribute to near-term gold production. During Q2 a total of 129,000 ft (39,300 meters (m)) of surface exploration drilling was completed at Black Fox Complex, for a year-to-date total of 220,000 ft (66,900 m).
“Our drilling continues to deliver very encouraging results, particularly from the three project areas highlighted in this release: Stock East, Froome and Gibson. Continued drilling success reinforces our view about the strong exploration potential of both the Black Fox and Stock properties,” stated Sylvain Guerard, Senior Vice-President Exploration.
Three of our exploration targets are covered in this release: Stock East, Froome and Gibson. Underground delineation drilling intercepts from Black Fox are also included, along with a revised Black Fox Mine resource estimate, which eliminates the Inferred resource category and increases the Indicated ounces and grade.
Stock East
The Stock Mine property covers a 4 mile (6.5 km) section of the Destor-Porcupine fault, and produced 137,000 gold ounces at a grade of 5.5 g/t between 1989 and 2005. Our winter drilling program was designed to follow-up on historical intersections and geophysical targets; it returned better than expected results at the Stock East target and prompted an expanded 66,000 ft (20,000 m) drilling program beginning in early June. Three drill rigs are currently active and will infill the Stock East target, test the depth extension of the Stock Mine below 500 m, and attempt to join mineralization at Stock East with the historical Stock Mine over a 2,000 m long trend (see Figure 1).
Stock East has a strike length of approximately 500 m and extends vertically from surface to a depth of at least 450 m. Its proximity to our mill facility makes Stock’s potential for an open-pittable deposit a particularly attractive target.

The Froome deposit is located 2,800 ft (850 m) to the West of the Black Fox open pit. It was discovered in 2014 and has a current Indicated resource of 159,000 gold ounces at a grade of 5.26 g/t.
Drilling at Froome during Q2 has identified a mineralized structure in the footwall, approximately 150 m North of the Main Froome Deposit (see Figure 2). The gold-bearing trend hosts clusters of positive drill intersections at Froome Northwest, North and Southeast that may lead to the definition of additional zones of mineralization proximal to the Froome Deposit. In addition, new drill intersections below the Froome Deposit suggest some incremental resource expansion potential. The potential to develop underground access to the Froome Deposit through mineralization in the footwall could provide a major enhancement to the project’s economics and will be evaluated once drilling to better define the zones is complete.
Footwall drilling highlights include the following intersections:
19.42 g/t gold over 2.5 m, including 52.7 g/t gold over 0.83 m at the Footwall NW area;
7.97 g/t gold over 5.99 m at the Footwall North area; and
7.91 g/t gold over 3.12 m, including 13.9 g/t gold over 1.56 m at the Footwall SE area.
Drilling down-dip of the Froome Deposit encountered 4.04 g/t gold over 7 m, suggesting the mineralization continues at depth. Drilling at Froome will continue in Q3 to follow up on these results.

Gibson
The Gibson exploration target area is adjacent the Grey Fox Deposit, where Indicated resources of 465,000 gold ounces at a grade of 6.64 g/t, and Inferred resources of 100,000 gold ounces at 6.83 g/t are currently defined.
The present dimensions of the Gibson Zone mineralization are approximately 100 m in length along strike and 400 m depth from near surface. Additional drilling is underway to better define the extent and orientation of the mineralization.
Hole 18GF-1079 returned 3.11 g/t gold over 34 m (core length), including 10.81 g/t gold over 6 m, from a new style of breccia mineralization identified at the Gibson area. This new intersection suggests the potential for extension of the mineralization to a 500 m depth below surface. Drilling will continue in Q3 to further assess the potential depth extension.

Black Fox Underground
During Q2 a significant portion of the underground drilling was dedicated to confirming and expanding known mineralized trends that are located close to current workings and that could be brought into production quickly. Definition drilling to the east of 560 Central Zone (CZ) has extended the east sill nearly 30 m. Drill intercepts have recently been confirmed with high grade chip samples that were taken across development faces, including: 27.65 g/t gold over 3.4 m and 90.22 g/t gold over 3.3 m.

Mining and Processing Details
The Fenix Project involves a two-phase development process. phase 1 includes the reprocessing of material on the gold heap leach pad at the existing El Gallo Gold Mine, and phase 2 includes the processing of open pit gold and silver mineralization from several deposits including El Gallo Silver, Palmarito, El Encuentro and Carrisalejo.
The process plant would use conventional and proven mineral processing and precious metals recovery technologies. phase 1 would have a throughput rate of 5,000 tonnes per day (tpd). During phase 2 fresh mineralized material from the higher grade silver deposits (El Gallo Silver primarily) can only be processed at a maximum of 3,250 tpd.
The selected process recovery methods are based on separate treatment of heap leach material (phase 1) and fresh mineralised material from other deposits (phase 2). phase 1 operation would target gold recovery from the heap leach pad material using a conventional ball grinding mill and a hybrid carbon-in-leach (CIL) circuit to recover gold onto activated carbon. Industry standard elution, electrowinning and smelting circuits would be used to produce a dore product.
In phase 2 the process facility would be modified to enable treatment of mineralized material from El Gallo Silver followed by other deposits in the complex. phase 2 operations would employ conventional flotation technology followed by intensive leaching and zinc precipitation using the Merrill Crowe process for silver and gold recovery. The phase 1 CIL plant would continue to be used for leaching of the flotation tailings to maximize overall silver recoveries during phase 2. phase 2 would also use the existing three stage crushing plant to prepare material for delivery to the grinding circuit.
Tailings produced during the operation would be stored in a mined-out open pit at the El Gallo Gold Mine. As part of this process, tailings deposition would include a delivery system designed to maximize tailings consolidation and water recovery.
The proposed process plant and the El Gallo Silver deposit are separated by about 6.5 km; requiring construction of a dedicated haul road for the transport of mineralized material. A new substation and power line would connect both projects to the national electrical grid.
Over the mine life, production would total 17.2-million tonnes of mineralized material at an average head grade 1.20 g/t AuEq containing 667 koz AuEq, and recovering a total of 563 koz AuEq. The planned production schedule is shown on Table 2.

Capital and Operating Costs
The Fenix Project's low up-front capital requirements are primarily due to:
Utilizing existing infrastructure at the El Gallo Gold Mine;
Commissioning a tailings storage facility in an existing pit;
Significantly reducing the required leach tank volumes for El Gallo Silver processing.
phase 1 initial capital expenditure is estimated at $41-million, phase 2 additional expansion capital expenditure is $30-million, and sustaining capital and closure obligations of $10-million brings the total LOM capital required to $81-million.
Mining and operating costs were estimated based on process design criteria, equipment lease rates, labor, reagent, grid power supply, diesel fuel, explosives, maintenance, and other miscellaneous costs. All costs are in Q1 2018 dollars.

The current operation at the El Gallo Gold Mine is a fully permitted open pit mine with a heap leach and ADR process facilities. El Gallo Silver and Palmarito are fully permitted for the construction of a CIL mill and drystack tailings facility. Some amendments to the permits are required for Project Fenix.
Future Permitting & Timing
phase 1 requires amendment of the current permits to include the construction of a mill and leach circuit at the location of the existing El Gallo Gold Mine for the reprocessing of the heap leach pad material. The permit amendment will also include the backfilling of the Samaniego pit with mill tailings as part of an integrated concurrent closure plan for the El Gallo Gold Mine. phase 2 permitting will require authorization to augment the tailings volume to be stored in the Samaniego pit, and El Gallo Silver permits require amendments to change the processing location to El Gallo Gold.
The Fenix Project has CONAGUA(11) approval for the extraction of groundwater and for the construction of wells.
Advancing the project will require permit amendments and approval by the Federal Environmental Authority (SEMARNAT) for phase 1 and subsequently for phase 2.
The company seeks to obtain approval of the phase 1 El Gallo permit modifications by Q4 2018 and phase 2 approvals by Q3 2019. Further project advancement in 2019 is subject to permit approvals.
Resource Estimates
Estimated resources for the Fenix Project are comprised only of material within the boundaries of conceptual pit shells, except for the El Gallo heap leach pad and Palmarito dumps, which are considered available for reprocessing.

Metallurgical Testing
Preliminary metallurgical test work conducted in 2018 indicated that the El Gallo Gold heap leach pad material would be amenable to direct cyanidation following conventional grinding. Test work identified moderate levels of soluble copper and zinc.
From 2010 to 2016 extensive metallurgical test work has been conducted on samples from the El Gallo Silver deposit using a direct cyanidation flow sheet. From 2017 to 2018 metallurgical test work has been focused on using conventional flotation techniques to separate the slower leaching minerals to enable separate cyanide leaching of bulk flotation concentrate and flotation tailings streams with tailored leach conditions to reduce overall size of the leaching circuit.
Results have proved favorable and a flowsheet incorporating bulk flotation and separate leaching of bulk flotation concentrates and tailings for treatment of El Gallo Silver has been adopted.
Historical test work records have been utilized to gain a preliminary understanding of the remaining resources along with some scoping test work conducted in 2018 to determine how material from the other higher-grade gold and silver deposits included in the conceptual production schedule would respond to the selected flowsheet.
LOM METAL RECOVERIES FOR THE PRODUCTION MODEL
Resource area LOM gold recovery LOM silver recovery
El Gallo heap leach pad 88% -
El Gallo silver 75% 86%
Palmarito 85% 75%
Carrisalejo 75% 85%
El Encuentro 90% 65%
Results from the scoping tests indicate that the Carrisalejo material will likely perform similarly to El Gallo Silver with respect to silver recovery. Scoping test results showed only modest silver recovery from flotation for the Palmarito sample. However, separate cyanide leaching of the bulk flotation concentrates and flotation tailings streams achieved positive results. The treatment process for Palmarito and Carrisalejo open pit material has therefore been assumed to be similar to El Gallo Silver pending confirmation through additional sampling and metallurgical test work.
For the preliminary economic assessment metallurgical samples selected for testing were assumed to be representative. Note that the Palmarito, Carrisalejo and El Encuentro deposits included in the production schedule have only been subjected to scoping level metallurgical test work using the selected process flowsheet.
Further sampling and test work is required to better understand the response of each of the deposits to the selected flowsheet.
Exploration
In recent years, exploration efforts at the El Gallo Complex have focused on both near-mine and property-wide targets. Near-mine drilling efforts have been successful in delineating and extending mineralization near the Samaniego and Sagrado Corazon pits. The new gold mineralization generally contains sulfides that could be processed in the phase 2 process plant. At the property scale significant mineralization has been confirmed at the El Encuentro zone, which is located 10 km from the El Gallo Gold Mine.
A property-wide soil geochemical survey was completed earlier this year and results indicate the potential for extensions of known zones of sulfide mineralization. In addition, multiple targets were identified from the survey, and field evaluation and ranking of targets for drill testing is in progress.
Further Optimization, Cost Reductions and Project Potential
The company believes there are opportunities to further improve the economics of the Fenix Project through ongoing testing and trade-off studies that will be continued throughout 2018.
Capital cost estimates for the project are to a level of accuracy that is consistent with a preliminary economic assessment technical report . During the next 14 months we will continue to review mineral processing, mine sequencing, material transportation and tailings disposal options ; and the flow sheet will be optimized by undertaking trade-off studies, update cost models and additional metallurgical testwork.

Mining and Processing Details
The Fenix Project involves a two-phase development process. phase 1 includes the reprocessing of material on the gold heap leach pad at the existing El Gallo Gold Mine, and phase 2 includes the processing of open pit gold and silver mineralization from several deposits including El Gallo Silver, Palmarito, El Encuentro and Carrisalejo.
The process plant would use conventional and proven mineral processing and precious metals recovery technologies. phase 1 would have a throughput rate of 5,000 tonnes per day (tpd). During phase 2 fresh mineralized material from the higher grade silver deposits (El Gallo Silver primarily) can only be processed at a maximum of 3,250 tpd.
The selected process recovery methods are based on separate treatment of heap leach material (phase 1) and fresh mineralised material from other deposits (phase 2). phase 1 operation would target gold recovery from the heap leach pad material using a conventional ball grinding mill and a hybrid carbon-in-leach (CIL) circuit to recover gold onto activated carbon. Industry standard elution, electrowinning and smelting circuits would be used to produce a dore product.
In phase 2 the process facility would be modified to enable treatment of mineralized material from El Gallo Silver followed by other deposits in the complex. phase 2 operations would employ conventional flotation technology followed by intensive leaching and zinc precipitation using the Merrill Crowe process for silver and gold recovery. The phase 1 CIL plant would continue to be used for leaching of the flotation tailings to maximize overall silver recoveries during phase 2. phase 2 would also use the existing three stage crushing plant to prepare material for delivery to the grinding circuit.
Tailings produced during the operation would be stored in a mined-out open pit at the El Gallo Gold Mine. As part of this process, tailings deposition would include a delivery system designed to maximize tailings consolidation and water recovery.
The proposed process plant and the El Gallo Silver deposit are separated by about 6.5 km; requiring construction of a dedicated haul road for the transport of mineralized material. A new substation and power line would connect both projects to the national electrical grid.
Over the mine life, production would total 17.2-million tonnes of mineralized material at an average head grade 1.20 g/t AuEq containing 667 koz AuEq, and recovering a total of 563 koz AuEq. The planned production schedule is shown on Table 2.

Capital and Operating Costs
The Fenix Project's low up-front capital requirements are primarily due to:
Utilizing existing infrastructure at the El Gallo Gold Mine;
Commissioning a tailings storage facility in an existing pit;
Significantly reducing the required leach tank volumes for El Gallo Silver processing.
phase 1 initial capital expenditure is estimated at $41-million, phase 2 additional expansion capital expenditure is $30-million, and sustaining capital and closure obligations of $10-million brings the total LOM capital required to $81-million.
Mining and operating costs were estimated based on process design criteria, equipment lease rates, labor, reagent, grid power supply, diesel fuel, explosives, maintenance, and other miscellaneous costs. All costs are in Q1 2018 dollars.

Wenn es nach mir gehen sollte, sollte er Recht haben.
Ob es aber so kommt, leider weiss das Keiner ?Bereitet Gold eine Trendumkehr vor?
27. Juni 2018
Aktuell kann der Goldpreis nicht von der schlechten Stimmung an der Börse, die eine Reaktion auf die eskalierenden Handelsstreitigkeiten zwischen den USA und ihren größten Handelspartnern entstand, profitieren. Im Gegenteil, Gold gab die letzten Tage weiter nach. Ein Analyst allerdings erwartet, dass dies nur das Vorspiel einer Trendumkehr ist und der Goldpreis wieder deutlich zulegen könnte.
