ON MEXICO ISSUES

  • Almaden Minerals Ltd. informed that “a lower court in Puebla State has ruled that Mexico’s mineral title system is unconstitutional because consultation is not required before the granting of mineral title………..This ruling can be appealed by both the Government of Mexico and Almaden. The Company believes that this lawsuit is part of a broad effort by special interest groups to change the mining law and there are other similar actions active across Mexico”. Almaden stated that no communities within the company’s current mining concessions on its Ixtaca project in Puebla are party to this lawsuit.
  • Fresnillo PLC. Presented its 2018 annual report. It is here recommended to all interested in the mining business in Mexico to take a look to the report (http://www.fresnilloplc.com/media/412015/fres-30452-annual-report-2018-web.pdf), especially on the section “Managing our risks”. In the said section, the risks of participating in the industry in Mexico are assessed, including those of metal prices, potential actions by the government, access to land, security, public perception against mining, safety, union relations, exploration, project performance, cyber security, environmental incidents and human resources. Although the report had in mind Fresnillo’s particular situation as one of the largest Mexican mining conglomerates, many parts of the evaluation concern risks that affect all mining enterprises in the country.

The Mining and Exploration News in Mexico: Highlights on the First Week of April, 2019

By Jorge Cirett

During the 14th week of the year (April 1st to April 7th, 2019), at least 24 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, an initiative with anti-mining tones was discarded by the Senate. The undersecretary of mining stated that no changes to the mining law, or tax increases in mining are envisaged by AMLO’s administration, and that the focus is to be in decreasing the regulatory load to incentivize the sector. On the other hand, he stated that regulations have to be actualized, highlighting community consultations. ON EXPLORATION, In Sonora, Minaurum presented drilling results from several vein systems at its Alamos Silver property; Aloro submitted a new environmental permit for its Venados project. In Chihuahua, Sable Resources released a thick, good grade intercept from one hole at its Margarita project. In Veracruz, Azucar Metals disclosed good Au-Cu results from one more hole at its El Cobre property.  ON MINING, Consolidated Zinc has a new toll agreement for its Plomosas mine in Chihuahua. Endeavour Silver achieved commercial production at its El Compas mine in Zacatecas.

ON MEXICO ISSUES

  • An initiative with anti-mining tones was discarded by the senate. The initiative presented on November 2018 by the now deceased senator Angelica Garcia, caused a fall in the value of mining companies in the Mexican stock market at the time of its presentation. The Comisiones Unidas de Mineria y Desarrollo Regional y de Estudios Legislativos discarded the proposal on March 27th, based on multiple deficiencies regarding operational overlapping of several government organisms and the lack of well-defined procedures on environmental and negative social impact issues.
  • Francisco Quiroga, undersecretary of mining, in an interview with El Financiero Bloomberg, stated that the Federal Government is not to realize changes to the Mining Law, nor to impose a tax increase in the mining industry. The priority, he said, is to reduce the regulatory load and to augment the financing of projects. He added that regulations have to be actualized in maters like community consults, but that there is no need to change the Mining Law. He also pointed that there are not going to be legal changes on the direct foreign investment in mining.

ON EXPLORATION

Senado desecha iniciativa antiminera.- Mundo Minero

http://www.mundominero.mx/notacompleta.php?id=5238

En noviembre pasado, la Senadora Angélica García (†) presentó una iniciativa que buscaba modificar la Ley Minera para crear nuevos impuestos e imponer una serie de causas para cancelar concesiones; propuesta que golpeó profundamente al sector y que finalmente ha sido desechada.

El anuncio derivó en que las mineras Grupo México e Industrias Peñoles, por citar a las principales afectadas, perdieran en conjunto 32,000 millones de pesos de valor en el mercado en un plazo de tres días. 

Entre los cambios propuestos figuraba facultar al Servicio Geológico Mexicano para que pudiera realizar estudios de impacto social; facultar a la Secretaría de Economía para que pudiera declarar zonas inviables de explotación o en conflicto por impacto social negativo, y en este marco cancelar concesiones; y obligar a los titulares de concesiones a destinar “un monto para el desarrollo humano y sustentable de las comunidades o localidades en las que realicen sus actividades de exploración y explotación”.

Si bien la iniciativa fue congelada a los pocos días de su presentación, no dejaba de ser una amenaza latente para el sector, mas hoy las Comisiones Unidas de Minería y Desarrollo Regional y de Estudios Legislativos han desechado y archivado como concluida dicha propuesta.

La instancia referida declaró: “En materia presupuestaria se encontró que la iniciativa es incompleta, ya que no se define el costo fiscal que implican tanto las nuevas funciones asignadas a la Secretaría de Economía y al Servicio Geológico Mexicano, así como las posibles cancelaciones mineras por el impacto de las medidas añadidas”.

De igual forma, las Comisiones Unidas señalan que la propuesta no establece procedimientos precisos para declarar zonas inviables o de conflicto por impacto social negativo, y añade que la NOM-120-SEMARNAT-2011 ya se encarga de los cuidados ambientales obligatorios, las mineras ya pagan impuestos adicionales destinados al Fondo Minero, y el SGM no cuenta con la capacidad técnica para realizar estudios de impacto social, entre otros puntos

SE pide a mineros canadienses aceptar las consultas públicas.- El Financiero

https://www.elfinanciero.com.mx/economia/se-pide-a-mineros-canadienses-aceptar-las-consultas-publicas

El subsecretario de Minería de la Secretaría de Economía, Francisco Quiroga, hizo un llamado a las empresas mineras canadienses sobre aceptar las consultas públicas para evitar daños ambientales y sociales.

En un comunicado, el funcionario dijo que esto lo expuso en el marco de la edición 2019 del Asociación de buscadores y desarrolladores de Canadá (PDAC, por sus siglas en inglés), foro en el que se reunieron representantes de la industria minera de más de 130 países.

También pidió cumplimiento tributario, protección ambiental y el respeto a los derechos humanos por parte de las empresas para evitar el cierre de minas.

“La vida humana, los desastres naturales, y el gobierno como un regulador imparcial, no son negociables”, señaló el funcionario.

Quiroga enfatizó en que México escaló 15 lugares como destino de inversión minera, de acuerdo con el reporte del Instituto Fraser, que anualmente presenta la opinión de empresarios e inversionistas de todo el mundo sobre las jurisdicciones o territorios más atractivos para la inversión del sector minero a nivel global.

“Nos comprometemos a proporcionar un trato justo e imparcial a todos los participantes de la industria (…) la actitud de los funcionarios es de servicio, de austeridad y de honestidad, con miras a la resolución efectiva de problemas, lo que incluye una colaboración activa con otras ramas del gobierno mexicano, comunidades, sindicatos, cámaras industriales, asociaciones comerciales y otros gobiernos”, refirió Francisco Quiroga.

Además, el subsecretario de minería ofreció una simplificación administrativa a los mineros por medio de una ventanilla única para sus trámites, así como solicitudes al gobierno.

 ON MEXICO ISSUES

  • Michael Harvey, director of Corporate Affairs for GoldCorp Inc., declared that Zacatecas has lost attractiveness for mining after the Supreme Court of Justice of the Nation (SCJN) declared constitutional 4 taxes called ecological (Extraction of Minerals, Emission of Gases to the Atmosphere, Emission of Contaminants to the Soil, Subsoil and Water and the Deposit and Storage of Residues) on the mining sector. It sends a very negative signal about the stability of the investment in Zacatecas.

ON EXPLORATION

  • Silver One Resources Inc., commenced a 1,000m drilling program at its Peñasco Quemado project in Sonora. The drilling program will test three targets selected on coincidental geochemical and geophysical anomalies. The company will test two targets in the eastern part of the property: a) the down-dip extension of the drill defined historic Ag resource area, interpreted as a shallow southwest-dipping replacement manto, coincident with a low-intermediate resistivity anomaly, and b) the along-strike extension of the historic Ag resource area as identified by strong > 3 km long southeast trending Zn, Pb, Ba, and Mn in soil anomalies and partially coincident with geophysical anomalies. In the western part of the property, Silver One will test strong Zn, Pb, and Cu soil anomalies with coincidental geophysics in an area drill tested by Silvermex in 2008 where significant intersections were encountered as that in Hole PQRC51 with 4.5m of 340 g/t Ag at a depth of 88m from surface.

ON MEXICO ISSUES

  • The Mining Sub Secretariat head, Francisco Quiroga, informed the Mexican government is reviewing five thousand concessions in process of cancellation, as well as another five thousand in process of liberation, acknowledging a big and growing backlog.

ON EXPLORATION

  • Sable Resources Ltd. completed a leach test on core from the first phase drilling at its Margarita project in Chihuahua. The purpose was to investigate the response of three samples (684, 341, 149 gpt Ag) to silver leaching with cyanide in a bottle roll test. The two higher grade samples had a recovery of 70 and 71 percent Ag after 48 hours, while the lower grade sample had a recovery of 37 percent on the same time lapse. The second stage drilling at Margarita initiated in January, consisting of a minimum of 19 holes for a total of 3000 m, to test extensions and infill of the Margarita vein and the Marie, Juliana, Fabiana and El Caido veins. Six holes have been completed, with a best vein intercept of 12.4 m starting at 30.9 m. Sable received title for the Manzana II application, reducing the size to 39,396 hectares in 11 concessions. Vinata is a drill-ready low-intermediate sulfidation project within these concessions, in which a series of quartz veins outcrop along a strike length of about 1,150 m in volcanic rocks. “The system consists of multiple sub-parallel veins and stockwork zones over a width of between 15m and 170m. Individual veins vary in width from <1m up to about 12 m><1 m up to about 12 m”.
  • Aloro Mining Corp. completed 12 RC holes for a total of 1,747 m at its Los Venados project in Sonora. The drill program was designed to test a felsic dome complex NW of the Estrella pit, at the Mulatos mine. The thickest intercept of mineralization was 18 m @ 0.2 gpt Au. Other relevant intervals comprise 3.05 m @ 1.45 gpt, 4.57 m @ 1.72 gpt. The style of mineralization of one of the holes, like the coarse vuggy nature with crystalline quartz, octahedral pyrite, and tetrahedrite is deemed as very significant, and resembling the high-grade part of the nearby Mulatos deposit.
  • Gainey Capital Corp. reported first-pass sampling on its newly optioned Las Margarita project in Durango confirmed a 1,500-1600 m strike length for the main vein system. Preliminary work consisting of 42 samples resulted in 21 with over 1 gpt, with 11 of those assaying more than 5 gpt Au, peaking at 40.0 gpt Au.

ON MINING

  • United States Antimony Corp. has dismantled and trucked equipment from its Reynosa pant (Tamaulipas) to other USAC operations in Mexico and the United States. A lot of equipment, tools and materials were transported to the Madero smelter in Coahuila. The Madero plant received seven truckloads of Wadley (San Luis Potosi) direct shipping ore with a total of 128 K pounds of contained Sb. The assembly of the cyanide leach plant at the Puerto Blanco mill in Guanajuato is progressing. “Production from the caustic leach plant at Madero to process the flotation concentrates has resulted in close to a 100% recovery of the gold and silver”. Estimated Sb production for January is 156.6 K Lb antimony.
  • GoGold Resources Inc. reported a net income of $8.2 M for the last quarter of 2018. The previously announced sale of the 2% net smelter royalty was closed. “The closing of the sale of the royalty concludes the Corporation’s involvement with the Santa Gertrudis project which was initially acquired in 2014. Net consideration on the sale of assets associated with the Santa Gertrudis project was $88.6 million, less costs of $24.5 million resulting in a pre-tax gain of $64.1 million over the life of the project”. GoGold produced 325.1 K Oz AgEq.

ON FINANCING

  • Kootenay Silver Inc. Announced a non-brokered private placement to raise gross proceeds of up to $2.5 M.  (La Cigarra, Chihuahua).

Algunas cancelaciones han sido solicitadas por activistas y ambientalistas; hay más de 20,000 trámites pendientes (liberación de terrenos, revisiones, entre otros), dijo el subsecretario de Minería, Francisco Quiroga.

El gobierno mexicano revisa posibles anomalías en más de 5,000 concesiones mineras que tienen trámites de cancelación, informó este miércoles el subsecretario de Minería, Francisco Quiroga.

En el Registro Público de Minería hay 25,221 títulos vigentes de concesión minera, que amparan 20 millones 970,000 hectáreas.

“Tenemos miles de trámites de cancelación pendientes, los estamos revisando para asegurarnos que se hicieron de manera correcta y que no se afectan los derechos de ninguna de las partes, más de 5,000”, dijo Quiroga a periodistas, en el México Mining Forum 2019, celebrado en la Ciudad de México.

Algunas cancelaciones de concesiones han sido solicitadas por activistas y ambientalistas.

“Tenemos más de 20,000 trámites pendientes de los cuales más de 5,000 son de liberación de terrenos, más de 5,000 son cancelaciones; tenemos que asegurarnos que esto se hace de la manera correcta para no afectar derechos, para no generar mayor incertidumbre y también para no generarnos mayores trámites”, añadió Quiroga.

El resto de los trámites corresponden supervisiones y revisiones de obligaciones, entre otros. “Tenemos un rezago grande y creciente”, dijo el funcionario.

Para operar una unidad minera se requiere el respaldo de las comunidades establecidas en la zona y, para ello, es primordial llevar a cabo una consulta. “Ése es uno de los medios para buscar conjunción de voluntades”, comentó.

En noviembre pasado, el grupo parlamentario del partido Movimiento Regeneración Nacional (Morena) en la Cámara de Senadores propuso un paquete de reformas a la Ley Minera que incluye, entre otros aspectos, la cancelación de concesiones.

De aprobarse la iniciativa correspondiente, el Servicio Geológico Mexicano podrá realizar estudios de impacto social respecto a las áreas objeto de concesión y asignación mineras, y la Secretaría de Economía declarar zonas inviables de explotación o en conflicto por impacto social negativo, en cuyo caso procedería la cancelación de concesiones y asignaciones. Los cambios buscan garantizar que toda concesión, asignación o zona que se incorpore a reservas mineras atienda los principios de sostenibilidad y respeto de los derechos humanos de las comunidades y pueblos de las regiones en los que se pretendan desarrollar.

Adicionalmente, obligaría a los titulares de concesiones mineras a que destinen un monto para el desarrollo humano y sustentable de las comunidades o localidades en las que realicen sus actividades de exploración y explotación.

El mes pesado, el senador Napoleón Gómez Urrutia, quien encabeza el mayor sindicato minero del país, dijo a Reuters que impulsará una regulación más estricta para las nuevas concesiones en la industria, así como menos restricciones para cancelar permisos de exploración y explotación. La industria minera de México es un importante generador de ingresos, que aporta 8.3% al Producto Interno Bruto (PIB) industrial y 2.5% al PIB nacional. Brinda soporte a más de 370,000 empleos directos y más de 1.7 millones de empleos indirectos.

La lista de grandes empresas mineras de propiedad mexicana incluye a Peñoles, Minera Frisco, Grupo México, Peña Colorada y Mexicana de Cobre. Otras importantes empresas contratistas y proveedores de servicios de propiedad mexicana incluyen a Signum, Cominvi, Alfil y GDI.

Mineras caen en bolsa

Luego del anuncio, las acciones de las empresas del sector minero reaccionaron negativamente al presentar una caída promedio de 1.02% y una pérdida en valor de mercado de 6,843 millones de pesos.

La empresa Grupo México fue la emisora que registró el mayor retroceso, tras presentar sus títulos una contracción de 1.71%, lo cual equivale a una pérdida de valor de mercado de alrededor de 6,151 millones de pesos, al pasar de 353,205 millones a 359,356 millones de pesos.

La minera regiomontana Autlán resultó la segunda con mayor retroceso en sus papeles, al mostrar un ajuste a la baja de 0.70%, y con ello se observó una disminución de 25 millones de pesos en valor de mercado, para ubicarse en 3,480 millones de pesos.

La empresa productora de oro y plata Grupo Peñoles también salió afectada, pero en menor medida, donde sus papeles registraron una disminución de 0.66%, originando una pérdida en su valor capitalización de 667 millones de pesos.  (Con información de Ricardo Jiménez)

Producirá 5.2 millones de onzas

México construye mina de plata de clase mundial

México construye un mina de plata, plomo y zinc con recursos de clase mundial (rentabilidad minera de largo plazo), la cual tendrá una producción anual de 5.2 millones de onzas de plata, lo que la ubicaría como la décima mayor mina de este metal precioso en el país.

Actualmente Sunshine Silver Mine y Dowa Holdings Co Ltd Japan construyen la mina, llamada Los Gatos, en el municipio de Satevó, en Chihuahua, con una inversión de 316 millones de dólares. La mina tendrá asimismo una capacidad de producción anual de 50 millones de libras de zinc (se colocaría como la cuarta más grande de este mineral en México) y 37 millones de libras de plomo (sería la segunda más grande en el país).

Esas posiciones son relativas, dado que consideran la clasificación de las principales minas de México en el 2017.

La construcción de Los Gatos comenzó a mediados de octubre del 2017, su puesta en marcha está prevista para finales del 2019 y, hasta septiembre del 2018, el efectivo gastado era de 135 millones de dólares.

El proyecto emplea actualmente a más de 1,000 personas, el contratista EPCM (Ingeniería, Adquisiciones, Construcción y Gestión) es M3 Ingeniería, el contratista de desarrollo minero es Cementación y la producción prevista del proyecto alcanza 2,500 ton/día.

De acuerdo con la Cámara Minera de México, 70% del territorio de México tiene un potencial geológico sobresaliente para la minería, y este potencial hace de México el cuarto destino de Inversión Extranjera Directa (IED) más grande del mundo en el sector y el primer destino en América Latina. La mayor parte de la IED fue realizada por empresas de España, Alemania, Israel, Estados Unidos y Canadá, este último con el mayor stock general de inversiones mineras en el país.

Si bien la industria minera de México está dominada por compañías canadienses, hay un importante capital mexicano involucrado en algunas de las minas más importantes que producen plata, oro y otros metales importantes, además de minerales no metálicos.

Francisco Quiroga, subsecretario de Minería de la Secretaría de Economía, dijo que el nuevo gobierno tendrá un enfoque más colaborativo y de transparencia entre las autoridades, las empresas, las comunidades, los políticos, los gremios y los sindicatos. En el México Mining Forum 2019, también dijo que la Secretaría de Economía operará una ventanilla única para realizar todos los trámites del sector.

By Jorge Cirett

During the 4th week of the year (January 21st to January 27th, 2019), at least 20 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, CAMIMEX expressed it is in contact with diverse actors of the public administration to consolidate the international competitivity of the mining industry. ON EXPLORATION, In Chihuahua, Radius Gold staked the 9,600 ha. Rambler project, covering a 9 km trend of epithermal mineralization. In Sinaloa, Kootenay Silver released interesting surface sample results from its Copalito project. In Durango, Orex is to perform a VTEM airborne survey on the San Luis Del Cordero property. In Hidalgo, Prospero Silver initiated drilling at the Pachuca SE project, with funding by Fortuna Silver. ON MINING, Pan American, Argonaut, Gold Resource, Fresnillo, Sierra Metals and Americas Silver presented Q4 and full year 2018 production results (by the way, anyone has heard from Frisco on this regard?). Endeavour presented its 2019 production guidance. ON FINANCING, Premier Gold signed a credit agreement with Investec Bank as administrative agent for the lenders for a US$50 M credit facility. ON RESOURCES AND DEVELOPMENT, Endeavour updated its reserve and resource base, for a consolidated grand total of 132 M Oz Ag, 1.042 M Oz Au. Premier Gold presented high-grade intercepts from drilling at Mercedes, Sonora, where over 40,000 m of drilling were completed in 2018. Leagold is to produce 200-220 K Oz Au in 2019 at Los Filos, Guerrero. Azure Minerals presented a favorable scoping study for its Oposura project in Sonora. Impact Silver is defining extensions on veins at its Zacualpan property in Estado de Mexico. Excellon released high-grade results from surface exploration at its Platosa mine in Durango. Capstone filed on Sedar a technical report for Cozamin, Zacatecas. ON DEALS AND CORPORATE ISSUES, Prospero Silver announced the signature of the option agreement with Fortuna Silver on the Pachuca SE project.

ON MEXICO ISSUES

  • CAMIMEX (Cámara Minera de México), in a response to El Financiero, expressed that any modification to the mining regulations has to take into account the wellbeing of the communities and its environment. The organization, of which leading companies like Peñoles, Grupo México and Minera Frisco are members, considers mining is one of the most supervised sectors in the country, with a modern and robust regulatory frame, following international standards, although areas of opportunity can always be identified.  “We have approached diverse authorities on the public administration and found openness to solve any pending issues and consolidate the international competitivity that benefits the country development”.

ON EXPLORATION

  • Orex Minerals Inc. contracted Geotech Ltd. To perform a VTEM (Versatile Time Domain Electromagnetic) airborne survey over its San Luis del Cordero project in Durango. Old mine workings and mineralized showings wrap around a Tertiary quartz-feldspar-porphyry intrusive. The helicopter-borne survey, with accompanying horizontal gradiometer and radiometric surveys, is to identify discrete conductive anomalies, as well as mapping lateral and vertical variations in resistivity. The airborne survey will be conducted over a grid at 100 m line-spacing for approximately 275 line-km, with measurements every 2-3 m along survey lines.
  • Prospero Silver Corp. has started phase 2 drilling at its Pachuca Se project in Hidalgo. Fortuna Silver Mines Inc. has an option to acquire up to a 70% interest in the 6,699 hectares project (24 km SE from Pachuca) by spending a total of US$8 M and completing a preliminary economic assessment (PEA), spending more than US$1 M in the first year. A six-hole, 4,200 m program started to test a number of potential drill targets. In a Fortuna funded program in early 2018, 1,800 m of drilling tested three distinct targets, intercepting what is interpreted to be the upper parts of a mineralized epithermal system.
  • Radius Gold Inc. staked a 9,600 ha property called the Rambler project, in Chihuahua, some 20 km NW from Radius’s Amalia project. Regional prospecting discovered epithermal mineralization in veins, vein breccias and disseminated zones over a 9 km trend, where samples with up to 16.5 gpt Au, 2,030 gpt Ag, 3.8% Cu, 13.9% Zn, 3.4% Pb were collected. Saucito is the main target area, where a 500 x 70 m stockwork returned an average of 177 gpt Ag on 31 samples. Other target areas with interesting rock chip sample results include La Machomera (up to 7.3 gpt Au, 469 gpt Ag), La India (up to 10.3 gpt Au, 16 gpt Ag), El Gringo (4.8 gpt Au, 3.8% Cu).
  • Kootenay Silver Inc. released results from surface sampling and mapping at the Copalito Ag-Au project in Sinaloa, same that covers an epithermal system with numerous veins 0.5-15 m in width and up to 2 km in strike length. Sampling Highlights include 7.2 Gpt Au, 3,770 gpt Ag at the 5 Señores and Agua veins respectively; 8.2 gpt Au, 583 gpt Ag across 1.1 m on the 5 Señores vein; 401 gpt Ag across 5.3 m on 5 Señores vein; 532 gpt Ag over 3.0 m and 306 gpt Ag over 4.9 m across the Agua vein; 17.4% Zn, 9.9% Pb, 0.52 gpt Au, 76 gpt Ag on a grab sample at Pillar vein and 5.1%, 1.6% and 1.5 Cu along the Cobriza vein. Of 117 rock samples collected, 29 returned silver grades over 90 gpt, including 11 over 300 gpt and 6 over 500 gpt.
