No more mining concessions in my term: AMLO.- El Financiero

The Mexican president, Andres Manuel Lopez Obrador announced this Sunday that under his government no more mining concessions are going to be delivered.

While on a political rally in Concepcion del Oro, Zacatecas, he stated that in 36 years 80 million hectares were concessioned, equivalent to 40 percent of the national territory.

He also accused business owners of using those permits only to speculate financially.

“To give concessions of the mining regions to national and foreign companies was a policy forwarded since the time of (Carlos) Salinas de Gortari and up to 80 million hectares were delivered for mining exploitation. To grasp it: let’s think in our territory. Mexico has 200 million hectares, and 80 million hectares, about 40 percent of the national territory. Never in History so much of our sovereign soil had been transferred”, he said.

He reiterated that current concessions are to continue, but no new ones are to be delivered.

“We are not to cancel (the concessions), but we are not to continue delivering new concessions for mining exploitation. Because it was too much what was delivered. If we analyze it, we are going to conclude that it wasn’t delivered to produce, but to speculate financially”, he said.

“With what has been delivered they have to produce. That’s the main purpose and not speculation. What we ask the mining companies is, first, take care of the environment, that no territory is destroyed, not to act as it is done in other countries”, he added.

He asked for Mexican miners to be paid as in the United States, or Canada, and that the same environmental rules be applied.

He made a call for the salaries of workers to be raised, with the same benefits.

As he has said in other rallies, Lopez Obrador warned that ONG’s are not to receive funds from the government budget.

“These realized intermediation work. It was supposed that these (ONG’s) delivered goods to the people and it wasn’t so. These kept the budget or a good amount of the budget and -hardly- purchased stocks of foods, distributed weevil bearing beans and kept must of the funds received”

No habrá más concesiones mineras en el sexenio: AMLO.- El Financiero


El presidente Andrés Manuel López Obrador anunció este domingo que durante su gobierno no se entregarán más concesiones mineras.

Durante un mitin en Concepción del Oro, Zacatecas, aseguró que en 36 años se concesionaron en el país 80 millones de hectáreas, que equivale al 40 por ciento del territorio nacional.

También acusó a los empresarios que sólo utilizaron los permisos para la especulación financiera.

“Concesionar las regiones mineras a empresas nacionales y a extranjeras fue una política que se impulsó desde la época de (Carlos) Salinas de Gortari y se llegaron a entregar 80 millones de hectáreas para la explotación minera. Para tener una idea: pensemos en nuestro territorio. México tienen 200 millones de hectáreas y se entregaron 80 millones de hectáreas, como el 40 por ciento del territorio nacional. Nunca en la historia se había enajenado tanto suelo patrio”, dijo.

Reiteró que se mantendrán las concesiones, pero que no se entregarán nuevas.

“No vamos a cancelarlas, pero ya no vamos a seguir entregando nuevas concesiones para la explotación minera. Porque fue mucho lo que se entregó. Si lo analizamos vamos a llegar a la conclusión que no se entregó para producir, sino para especular financieramente”, dijo.

“Ya con lo que entregaron tienen para producir. Ese es el propósito principal y no la especulación. Lo que pedimos a las empresas mineras es, primero, que se cuide el medio ambiente, que no se destruya el territorio, que no actúen como se hace en el extranjero”, añadió.

Pidió que a los mineros mexicanos se les pague como se hace en Estados Unidos o Canadá y se apliquen las mismas normas ambientales.

Hizo un llamado a que se vaya aumentando el salario de los trabajadores, y que haya los mismos beneficios.

Como la ha dicho en otros mítines, López Obrador advirtió que las organizaciones no gubernamentales no recibirán presupuesto público.

“Realizaban trabajo de intermediación. Se supone que entregaban los apoyos a la gente y no era así. Se quedaban con el presupuesto o con una buena cantidad del presupuesto, se entregaban los apoyos y -si acaso- compraban despensas, repartían frijol con gorgojo y se quedaban con la mayor parte del dinero que recibían”.

The Mining and Exploration News in Mexico: Highlights on the Second Week of June, 2019

IMG_1079 - copia

By Jorge Cirett

During the 26th week of the year (June 24th to June 30th, 2019), at least 43 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, a resolution by the Supreme Court is awaited to learn how the Mining Fund resources are to be allocated, if for social and environmental infrastructure (as planned) or as direct allocations to the people of the communities, the preferred method of the president (a method the opposition denounces as vote buying). In Sonora a local congressman introduced a bill for a new state tax on dirt extracted from open pits, a measure that if implemented is to pose a further weight in the already heavy fiscal load for mining companies in Mexico. Furthermore, the Economy Secretariat (Secretaria de Economia) published a letter stating that the “Protocol of Good Practice of Mining for the Public Consultation” (Protocolo de buenas practicas de la Minería para la consulta pública) is under review by the agency. It is not possible to underrate the importance of the review of this protocol, because if it is implemented incorrectly the result would impact fast and catastrophically the Mexican exploration industry. One of the more pressing issues is the fact that placing the consultation process before exploration takes place, would end most exploration in one swipe. If in doubt, just take a look to Oaxaca, where, although not being in the law you have to make the community consultation process before exploring, and the result is that hardly any exploration work is nowadays conducted in one of the states with the best mineralization potential in Mexico. Trust is hard to earn, let’s not throw it away so carelessly. ON EXPLORATION, In Zacatecas, Galore continues to drill at Dos Santos; Alien Metals updated on its exploration of Donovan 2 and Los Campos. ON MINING, Alien Metals released its financial results for 2018. ON FINANCING, Santacruz signed an agreement to extend the payment of a US$2.3 M loan. Galore is making a $1.5 M financing. Goldplay closed an oversubscribed financing for $1.37 M. Leagold completed a debt refinancing for a $200 M term loan and a $200 M revolving credit facility. ePower intends to conduct a private placement for Cdn$6 M. Sable granted 2.8 M incentive stock options. Alien Metals raised £350 K.  ON RESOURCES AND DEVELOPMENT, Mexus Gold  is to start leaching at Santa Elena, in Sonora. Telson reported significant underground channel sample results at Tahuehueto. Orla presented the result of the FS on Camino Rojo. Premier Gold presented results of its 42,000 m drilling campaign at Mercedes. Southern Silver file a technical report with updated resources on Cerro Las Minas. Santacruz presented results of drilling at Veta Grande. GoGold released results of drilling at Los Ricos. SilverCrest informed the decline has intersected the Babicanora vein at Las Chispas. Minera Alamos informed on the permitting of Santana. Almaden updated on permitting and legal issues at its Ixtaca project in Puebla. ON DEALS AND CORPORATE ISSUES, Millrock sold its Sonoran portfolio to Riverside. ePower Metals entered into a definitive agreement with Minera Alamos to acquire the Los Reyes project in Sinaloa. Silver Viper renegotiated much better terms on the lease of two properties within its La Virgina project in Sonora. Golden Minerals entered into an agreement under which Minera Autlan is to buy its Velardeña properties. Bacanora Lithoum signed an investment agreement and an offtake agreement with Ganfeng Lithium on its Sonora lithium project. Canasil and Pan American agreed on terms for the acquisition of Pan American of the Sandra Escobar project in Durango.


  • The Economy Secretariat is awaiting the resolution of the Supreme Court on the change of rules to apply the Mining Fund, which this year is anticipated to be amounting to 3.2 billion pesos (3,200 millones) or approximately US$168.4 M. The proposal by the present Federal government (ie.- the president) is to deliver the resources directly to the people to “augment the capacities” of the mining communities. The aim would be to organize the community and the service providers to be part of the service chain for the mining industry. The resources on the Mining Fund to date are to be funneled according with the current rules, until a resolution by the Supreme Court clarifies the issue.
  • In Sonora, local congressman Carlos Navarrete from the Encuentro Social party (allied to the Morena party) introduced a bill for a new State tax on dirt extracted from open pits (includes waste, sand, dimension stone, clays, limestone, lime, among others). The US$0.63 tax per cubic metre of material would be split 80/20 between the municipalities and the State. The resources would be utilized in physical investments and infrastructure with social impact, in the environment and urban development (The bill intends to use the resources thus gathered in the same way that those of the Mining Fund were supposed to be used, and for which a 7% federal royalty tax was imposed on mining a few years ago. Now that the current president Andrés Manuel Lopez Obrador intends to use the resources of the Mining Fund for his preferred programs, allied politicians are trying to make the mining industry pay even more taxes).
  • The Economy Secretariat published a letter on the “Protocol of Good Practice of Mining for the Public Consultation”. In the letter the Economy Secretariat states that the protocol is under review by the agency. On the Letter: The consultation process is to be applied to all communities that can be impacted by the mining activity. Also, both exploration and exploitation should be consulted before their realization. The responsible authority is to be the Economy Secretariat, with aid by the Instituto Nacional de los Pueblos Indigenas and other authorities (SEMARNAT, CONAGUA, CFE, local municipal and state governments), as well as the state and federal Human Rights Commissions.


  • Galore Resources Inc. informed its 2,500 m diamond core drilling program at the El Alamo target of its Dos Santos project in Zacatecas continues to progress well.

Cachetadita Minera

Sergio Sarmiento 

Alfonso Romo, jefe de la Oficina de la Presidencia, afirma que: “El primer trimestre nos dio una cachetadita”. Como jinete experimentado añadió: Eso es “como cuando montas a caballo, te vuelves a subir para montar mejor”.

            Para superar la contracción del primer trimestre, y conservar las posibilidades de crecer 4% al año en el sexenio, es importante mantener la inversión productiva, pero esto no ocurrirá si seguimos viendo casos en que los políticos extorsionan a los inversionistas.

            La mina de Peñasquito en Zacatecas es un ejemplo. Desde el pasado 27 de marzo sus accesos han sido bloqueados por integrantes del ejido de San Juan de Cedros, así como por líderes de la empresa transportista CAVA, también formada por miembros de ese ejido. El senador de Morena, José Narro Céspedes, parece ser el organizador de este bloqueo.

 La empresa señala que el mismo 27 de marzo que empezó el bloqueo el representante de los ejidatarios, Felipe Pinedo, asesor de Narro Céspedes, presentó “como principal exigencia un pago de 442 millones de dólares por la presunta afectación a un cuerpo de agua en dicha comunidad. Socios de CAVA indicaron que Pinedo y dos asesores jurídicos recibirían 80 millones de dólares de dicho pago”. La empresa ha afirmado que no cederá a lo que tilda de extorsión.

            El cierre de la mina ha tenido consecuencias negativas importantes en la zona. Peñasquito ha creado seis mil empleos directos y unos 14 mil indirectos. Es la segunda generadora de empleo en Zacatecas. La empresa ha tenido ya que suspender pagos a trabajadores, empleados, proveedores, contratistas y comunidades a las que otorga ayuda desde hace años.

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

By Jorge Cirett

During the 18th week of the year (April 29th to May 5th, 2019), at least 35 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, Newmont Goldcorp Corp. informed on the intention to temporarily suspend operations at the Peñasquito mine in Zacatecas, due to an illegal blockade lasting for more than a month now. More than 300 mine employees protested outside the Zacatecas Congress, accusing José Narro, senator by Morena (the president’s party) of instigating the blockade. Drill core from La Xora project in Nayarit was added to The Mexican Core Shack. ON EXPLORATION, Nine companies presented advances in the exploration of their properties: In Baja, One World Lithium has received the permits to drill its Salar Del Diablo property. In Sonora, Sonoro Metals disclosed assays for the first 15 RC holes of the second drilling campaign; Ridgestone updated the work done to date at Rebeico; Minaurum staked a large chunk of ground at its Alamos project. In Chihuahua, Silver Spruce released surface sample results from its Pino de Plata project; Radius Gold released exciting results from the first hole of the second drilling campaign at Amalia; Kootenay Silver has initiated drill road construction for its incoming campaign at Columba. In Jalisco, GoGold released results from its drilling campaign at Los Ricos. In Zacatecas, Alien Gold updated on the exploration effort at its Donovan 2 property. ON MINING, nine companies presented its first quarter 2019 results, while one company presented its 2018 results. ON FINANCING, First Mining, and Prize Mining are to raise $6 M and $1.5 M respectively. Leagold Mining secured a 200 M term loan and a 200 M revolving credit. ON RESOURCES AND DEVELOPMENT, no relevant news.  ON DEALS AND CORPORATE ISSUES, Alio Gold received notice of a civil claim from a former Rye Patch shareholder.  


  • Newmont Goldcorp Corp. informed on the intention to temporarily suspend operations at the Peñasquito mine in Zacatecas (one of the largest in Mexico, produced 272 K Oz Au in 2018), due to an illegal blockade by a trucking contractor and some members of the Cedros community that began on March 27, 2019. The company announced on April 9 that the trucking contracts will now be signed with independent truckers, to their economic benefit and to avoid the repeated extortion blockades by the current trucking contractor. Newmont Goldcorp denounced that the blockader’s public claims that focus in water quality and employment, turn in a direct petition for large amounts of money when done privately. The company asks for help from the Mexican and Zacatecan authorities to resolve the illegal blockade that affects the income of more than 20 thousand persons, directly or indirectly. On a different event, about 300 employees of Minera Peñasquito, protested outside the Zacatecas Congress against the illegal blockade that keeps paralyzed the Peñasquito mine. The protesters accused Jose Narro, senator by the president party, Morena, and his acolyte Felipe Pinedo of blackmailing the company with false water contamination statements.  
  • Core from La Xora project, in Nayarit, was added to the Mexican Core Shack (, under the epithermal low sulphidation section.


  • Sonoro Metals Corp.  reported assay results from the first 15 reverse circulation holes of the second phase drilling program at its Cerro Caliche property in Sonora. All holes encountered gold mineralization, which extend mineralization 1.25 Km NW from the Central Zone, where the first drill campaign defined a series of NW striking structures, outlining three shallow bulk tonnage oxidized mineralized zones in metasedimentary and volcanic rocks.

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. Telson Mining released historic metallurgical test results that support higher precious metal recoveries for its Campo Morado mine in Guerrero. Alamos Gold has produced 2 M Oz Au at the Mulatos mine in Sonora. Torex Gold produced 77.8 K Oz Au during the last quarter at its Limon-Guajes mine in Guerrero. GoGold produced 288.7 K Oz Ag in Parral, Chihuahua. Arcelor Mittal invested over US$1 B on its Michoacan plant in 2018.   ON FINANCING, Sonoro Metals raised $650K. Defiance Silver closed the second tranche of its financing, raising $1.06 M. Sable Resources announced an offering to raise up to $1.5 M.  ON RESOURCES AND DEVELOPMENT, Mag Silver disclosed development advances at Juanicipio, Zacatecas. Sierra Metals disclosed positive drill results from testing of a geophysical anomaly at Bolivar, Chihuahua. Evrim informed on the increase in resources by First Majestic at the Ermitaño project in Sonora.  ON DEALS AND CORPORATE ISSUES, Alamos Gold sold a portfolio of non-core royalties. Bacanora Lithium continues to negotiate with Oman for funding of the Sonora Lithium project. Premier Gold divested of several properties, including the Santa Teresa property in Baja California. 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).
