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.

American Silver and Pershing Gold continue on its path to business combination. GoldCorp’s shareholders support the business combination with Newmont.  


  • 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.


  • Minaurum Gold Inc. informed that three of the new vein systems at its Alamos Silver project host significant mineralisation at depth, and drilling has intersected five previously unknown blind veins. To date, 9 of the 15 vein systems identified have been drilled, and Minaurum plans to put at least one hole on each of these before turning to follow-up phase III drilling. Highlighted results from phase II drilling of new veins comprise: 9.6 m @ 198 gpt Ag, 0.17% Cu, 0.2% Pb, 0.9% Zn (or 269 gpt AgEq); 0.9 m @ 302 gpt Ag, 0.21% Cu, 0.5% Pb, 0.8% Zn (or 383 gpt AgEq); 2.05 m @ 181 gpt Ag, 0.15% Cu, 1.6% Pb, 1.5% Zn (or 338 gpt AgEq); 2.85 m @ 25 gpt Ag, 2.3% Pb, 10.6% Zn (or 618 gpt AgEq); 0.9 m @ 391 gpt Ag; 0.11% Cu, 0.4% Pb, 0.3% Zn (or 548 gpt AgEq).

ArcelorMittal lleva inversión extranjera siderúrgica a nivel histórico en México.- El Financiero

El proyecto de la acerera ArcelorMittal en Michoacán, donde destinó mil millones de dólares, llevó a nivel histórico la Inversión Extranjera Directa (IED) de la industria siderúrgica en México durante 2018.

El año pasado se ejercieron en el país mil 635.1 millones de dólares, nivel muy superior a los 361.4 millones de 2017 y el más elevado que se aplica en la industria desde 2007, de acuerdo con Información de la Secretaría de Economía.

En conferencia telefónica con analistas, Aditya Mittal, director de finanzas de la empresa india, destacó que mantienen su plan de inversiones de mil millones de dólares en México, pese a los aranceles que aplicó Estados Unidos a las importaciones de acero que se fabrica en ‘suelo azteca’.

Con estos recursos, la multinacional busca expandir su capacidad productiva en México, incluida una nueva línea de laminación, minería y la modernización de activos.

Según Aditya Mittal, el objetivo de dicha inversión es atender el mercado interno. La trasnacional importa 8 mil toneladas de acero al año para vender en México.

El ejecutivo consideró que con líneas como las de laminación, la multinacional podría obtener mejores márgenes de ganancia, además de volverse proveedores directos de industrias de gran crecimiento en el país, como la automotriz y la aeroespacial.

Las nuevas instalaciones del grupo se ubicarán cerca del Puerto de Lázaro Cárdenas, Michoacán, a fin de aprovechar las Zonas Económicas Especiales (ZEE).

En su reporte financiero al cuarto trimestre de 2018, la empresa detalló que con la nueva planta de Michoacán, su división México tendrá una capacidad de producción de 5.3 millones de toneladas, con lo cual mejorará la participación de productos de mayor valor agregado en sus ventas totales.

“Con el proyecto (de Michoacán) produciremos 2.5 millones de toneladas de acero laminado plano, 1.8 millones de acero largo y el resto formado en losas semi acabadas. Entrará en operación en el segundo trimestre del 2020”, detalló la multinacional.

Gobernadora anuncia reactivación de minera

Hermosillo, Sonora(GH)

La gobernadora Claudia Pavlovich Arellano anunció el reinicio de operaciones de la empresa minera ArcelorMittal México, ubicada en Rosario Tesopaco, la cual generará más de tres mil 500 empleos directos e indirectos.

En una reunión con el director general de la empresa minera ArcelorMittal México, Víctor Manuel Martínez Cairo, se confirmó la reactivación de la extracción minera de hierro en Sonora en la mina “El Volcán”.

A casi un año del paro de labores, la reanudación de las actividades en la mina “El Volcán” de ArcelorMittal México, provoca también el restablecimiento de actividades en la planta concentradora en Ciudad Obregón y la actividad portuaria en Guaymas, dijo Víctor Manuel Martínez Cairo.

México, entre los 10 principales productores de minerales, destaca,5bef9e0468eee2daf1d00cc86b15e291wk83p6ab.html

México es una potencia siderúrgica global y su industria minera contribuye con 4.0 por ciento del Producto Interno Bruto (PIB) nacional, afirmó César Camacho Quiroz, coordinador de la bancada priista en la Cámara de Diputados.

Al participar en la instalación de la Comisión Especial de Minería, destacó que México es líder en la producción de plata y está entre los 10 principales productores de 16 diferentes minerales.

Peñoles Invierte US 296 Millones en Nueva Mina de Plata en México


La empresa mexicana Peñoles invertirá 296 millones de dólares en su proyecto polimetálico Rey de Plata, en Guerrero, informó la Cámara Minera de México (Camimex).

El futuro minero son las fusiones: Camimex

Ante los bajos precios de los metales, la Cámara Minera de México (Camimex) anticipó un aumento en el número de fusiones y adquisiciones en el sector, ya que las empresas buscarán reducir costos y crear sinergias, pues el valor de esos procesos en el país superó los 2 mil millones de dólares.

La minería tuvo en 2015 uno de sus peores años; algunos analistas lo compararon con las crisis financiera mundial de 2008 y la asiática de 1997, al considerar que los precios de los metales fueron a la baja. El fierro cayó a su nivel más bajo desde mayo de 2009 — 40 dólares por tonelada—, el oro 8 por ciento, la plata 18 por ciento y el cobre 20 por ciento.

Ante el crecimiento económico bajo y volátil, con inflación moderada y poder de fijación de precios débiles de los metales, la Camimex destacó que se motivó a las empresas a buscar una reingeniería de los mecanismos generadores de capital mediante recompras de acciones y fusiones.

Southern Silver Intersects 29.5m Grading 107.4g/t Ag, 0.40% Cu, 1.1% Pb and 2.3% Zn (275g/t AgEq) at Cerro Las Minitas

VANCOUVER, BRITISH COLUMBIA–(Marketwired – June 13, 2016) – Southern Silver Exploration Corp. (TSX VENTURE:SSV)(FRANKFURT:SEG1)(SSE:SSVCL) (“Southern Silver”) reported today assay results from the first two holes (CLM-087/-088) from 2016 core drilling on the Cerro Las Minitas project, Durango State, Mexico which identified a new thick interval of continuous polymetallic semi-massive and massive sulphide mineralization in drill hole 15CLM-088. Highlights from drill hole CLM-088 include:

  • a 30.4m down hole interval (29.5m est. True Thickness) averaging 107.4g/t Ag, 0.40% Cu, 1.1% Pb and 2.3% Zn (275g/t AgEq) including a higher grade 7.3m interval (7.1m est. TT) averaging 190g/t Ag, 0.37% Cu, 3.4% Pb and 5.5% Zn (552g/t AgEq)

Mineralization in drill hole 16CLM-088 occurs in skarn on the margin of the Central Intrusion. Significantly, the intercept in 16CLM-088 is one of the thickest intervals of continuous high-grade mineralization identified on the property to date. The mineralization is open both down dip, to the west, and along strike to the north and northwest and represents an aggressive (~200 metre) step out from the previously modelled Blind and El Sol deposits and specifically drill hole 15CLM-081 (16.8m down hole interval 136g/t Ag, 0.5% Cu, 0.3% Pb and 4.5% Zn or 361g/t AgEq; see NR-14-15, December 1, 2015).
