  • 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.


  • 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.
  • SilverCrest Metals Inc., reported drill results and discover of the Babi Sur Vein within its Las Chispas project in Sonora.

Of the 14 intercepts with an average true width of 1.4 metres, six are greater than 400 g/t AgEq (400 to 3,555 g/t AgEq)”.
  • Silver Viper Minerals Corp., provided an update of the 2018 drilling program conducted at its La Virginia project in Sonora. 4,753m were completed in 20 core drill holes, over five distinct prospect areas, distributed along 11km of the prospective structural trend. “The highlight of 2018 was El Rubi, a never-before drilled showing, located some 1.5km north of any previous drilling.  El Rubi returned a best result of 6m true width (13.3m core length) averaging 3.16 g/t gold and 228g/t silver for a gold equivalent grade of 6.42g/t Au”.
  • Ethos Gold Corp., received the approved permits for trenching and drilling its La Purisima Au project in Chihuahua. Ethos announced the commencement of the trenching program and expects to start the drilling program in March, 2019.

By Jorge Cirett

During the 6th week of the year (February 4th to February 10th, 2019), at least 12 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, The head of the Sub Secretariat of Mining, Francisco Quiroga, elaborated on some of the backlogs its office faces. ON EXPLORATION, In Sonora, Aloro completed an RC drilling campaign at Los Venados. In Chihuahua, Sable is drilling the Margarita project, and preparing for the exploration of the Manzana II concessions. In Durango, Gainey reported first-pass sampling results on the Las Margarita project. ON MINING, USAC informed on its activities at its Mexican operations. GoGold reported on income for the last quarter of 2018. ON FINANCING, Kootenay and Palamina announced non-brokered private placements or amendments of placements for $2.5 and $2.2 M. ON RESOURCES AND DEVELOPMENT, Goldplay completed a new resource estimation at its San Marcial project in Sinaloa. Mexican Gold engaged a contractor to update the resource estimate at its Las Minas project in Veracruz. ON DEALS AND CORPORATE ISSUES, No relevant news.


  • 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.


  • 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.


  • 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.


  • Kootenay Silver Inc. Announced a non-brokered private placement to raise gross proceeds of up to $2.5 M.  (La Cigarra, Chihuahua).
  • Palamina Corp. amended its non-brokered private placement, to allow for the raising of up to $2.2 M (Santuario, Hidalgo).  


  • Goldplay Exploration Ltd. announced the completion of a NI-43-101 mineral resource estimate for the San Marcial project in Sinaloa. “The Mineral Resource consists of 36 million ounces (“Moz”) of silver equivalent (“AgEq”)2 at an average grade of 147 grams per tonne (“gpt”) AgEq in the Indicated category and an additional 11 Moz AgEq at an average grade of 99 gpt AgEq in the Inferred category…”. Highlighted points include: a) A shallow, high-grade Ag core zone, up to 40 m in thickness. It represents 3.0 million tonnes at an average grade of 239 gpt AgEq, 200 gpt Ag, equivalent to 23 M Oz AgEq and 19 M Oz Ag, respectively. B) 98% of the 36 M Oz AgEq Indicated Resource is potentially mineable by open pit. C) . Both the Breccia and surrounding Stockwork Zones outcrop at surface.
  • Mexican Gold Corp. informed the engagement of Mine Development Associates to provide and updated 43-101 resource on Mexican Gold’s Las Minas project in Veracruz. Since the initial resource in 2017, the company has drilled 6,454 m in 39 holes. “Additionally, higher grade mineralization was encountered in the late 2017 and early 2018 drilling in the El Dorado Dike contact zone. For example, drill hole LM-17-ED-40 encountered 38 metres grading 5.39 g/t Au, 17.1 g/t Ag and 2.20% Cu, while drill hole LM-18-ED-49 intercepted 38 metres of 4.51 g/t Au, 16.2 g/t Ag and 3.33% Cu.”.

Economía revisará 5,000 concesiones mineras en busca de anomalías

Roberto Morales 07 de febrero de 2019, 01:00

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.

Senadores Buscan Crear Nuveo Marco Jurídico Minero

La presidenta de la Comisión de Minería y Desarrollo Regional del Senado de la República, Geovanna del Carmen Bañuelos de La Torre, dijo que es necesario crear un nuevo marco jurídico que permita estandarizar las normas en materia de seguridad, salud y protección para los trabajadores y el cuidado del medio ambiente.

La senadora del Partido del Trabajo expresó que en ocasiones no ha sido la falta de legislación lo que impide que haya un pleno y sano desarrollo de la industria minera en México, sino el que el problema radica en que no se acatan a cabalidad las normas. “Por ello necesitamos impulsar y comprometer a todos los sectores y actores involucrados”
