ON MEXICO ISSUES

  • Three new mining facilities to be inaugurated in Durango in Q1 2022, according to Gustavo Kienttzle Baille (Secretaría de Desarrollo Económico del Estado). The construction of two mines in Pueblo Nuevo and one in Tepehuanes started in 2021 with a total investment of US$46 M.
  • According to Camimex (Cámara Minera de México) 60 thousand women work in the Mexican mining industry. This is a great advance, as only a few decades ago women were prohibited by law to work in mining.

ON EXPLORATION

  • One World Lithium Inc. presented assay results from water samples from the Salar del Diablo project in Baja California. Multiple water samples were collected at different depths from four holes, two drilled in 2019 and two more in 2021, with depths ranging from 191 to 647 m. All samples returned less than 0.5 mg/L Lithium, less than 100 mg/L Potassium and less than 5 mg/L Boron, the detection limit for each element. “Drilling conditions were challenging as the fine grained and poorly consolidated nature of sediments that were only poorly to moderately cemented resulted in abundant borehole unravelling and “caving” during drilling”.
  • Riverside Resources Inc. reported high-grade sample assay results from its La Union project in Sonora. Highlighted results comprise 83.2 gpt Au; 0.3 gpt Au, 4,816 gpt Ag, 10.3% Pb, 3.5% Zn; nil-Au, 8 gpt Ag, 2% Pb, 21.4% Zn;  0.1 gpt Au, 176 gpt Ag, 3.8% Pb, 19.8% Zn; 6.1 gpt Au, 23 gpt Ag, 8.2% Pb; 8.8 gpt Au, 183 gpt Ag, 3.9% Pb, 3.4% Zn from chips, 22.6 gpt Au, 20 gpt Ag; 4.2 gpt Au, 42 gpt Ag, 2.3% Pb, 3.5% Zn from dumps and 0.8 m @ 9.4 gpt Au, 108 gpt Ag, 1.6% Zn; 1.6 m @ 9.9 gpt Au, 54 gpt Ag, 2.5% Zn; 0.6 m @ 3.6 gpt Au, 373 gpt Ag, 7.3% Pb, 7.3% Zn; 1.5 m @ 2.6 gpt Au, 170 gpt Ag, 0.7% Pb, 6.6% Zn in chip channels. “Mineralization is found on surface associated with low angle faults, folds, with the thicker mineralized intervals being where high angle fault intersect with other structures creating ‘traps’”.
  • Aztec Minerals Corp. informed on work carried out in 2021 at the Cervantes project in Sonora. The ongoing 5,000 m reverse circulation drill program commenced on Q4 2021, with 14 holes on the California target, one at the California North prospect, one at the Jasper prospect and four to six holes on the Purisima target.
  • Monumental Minerals Corp. is to carry an airborne magnetic and radiometric survey over its Jemi project in Coahuila. The property is host to several rare earth element occurrences, like Neodymium (Nd), Praseodymium (Pr), dysprosium (Dy) and Terbium (Tb), with associated Tantalum (Ta), niobium (Nb) and zirconium (Zr). “The high-resolution helicopter-borne magnetic and radiometric survey will be flown at 100 m line spacing over an area of approximately 100 km2 for a total of 1,120 line-km. It will be centred on the 8 km diameter Sierra La Vasca intrusion complex that hosts the Jemi HREE mineral occurrences”.

ON MINING

  • Excellon Resources Inc. provided an update on its Platosa operations in Durango and company-wide exploration plans. The company is evaluating the continuation of mining activities at Platosa (commissioned in mid-2005) beyond mid-2021 as a result of increased labour and energy costs at the time that mining is entering an area of the deposit where mineralization steepens, with fewer vertical-tonnes-per-meter than historically encountered. The company keeps exploring the Platosa property, with a 2,700 m drill program planned in 2022 on the PND skarn target and is conducting an O18 isotope study on the CRD–style Jaboncillo target, 11 Km northwest of the Platosa mine. At the nearby Evolución project, a 4,600 m drilling program is planned.
  • GoGold Resources Corp. informed on the production during the Q4 2021 of 2,558 Oz Au, 195.7 K Oz Ag, 123 tonnes Cu (444.1 K Oz AgEq) at its Parral tailings operation in Chihuahua.
  • Endeavour Silver Corp. introduced its new Sustainable Strategy, with three-year targets. The strategic plan involves increasing the positive social impact for people, elevate the environmental stewardship of the planet and lead a healthy, long term business (Terronera, Jalisco).
  • Guanajuato Silver Company Ltd. announced it will begin to process mineralized material from third parties at its El Cubo mill in Guanajuato. Approximately 4,000 tonnes form a mining operation in the Guanajuato area have been contracted “It is GSilver’s intention to use the approximately 20,000 tonne per month of excess capacity at the El Cubo mill to profitably process mineralized material from various potential sources in the Guanajuato area. Whether the business arrangement is designed as toll milling, raw material purchasing, or profit sharing, if it serves to contribute to our bottom line and helps to expand our presence in the 480-year-old mining camp of Guanajuato, then we will pursue it”.

ON MEXICO ISSUES

  • Governors of Guerrero, Chihuahua, and Durango showed their support for the mining industry during the inauguration of the XXXIV International Mining Convention in Acapulco because it represents a lever for the economic development of the country. They promised to respect the rule of law to promote the investment in the sector that generates jobs and benefits to the communities where it operates.
  • Jaime Gutiérrez Núñez, president of The Mining Chamber of Mexico Camimex stated that the suspension of new mining concessions as well as the effects of the possible approval of the electricity reform and the heavy tax burden is generating strong uncertainty in the mining sector in Mexico.
  • Tonatiuh Herrera Gutiérrez, Undersecretary of Promotion and Environmental Regulations of the Secretariat of the Environment and Natural Resources (SEMARNAT), warned that the agency will keep consultations on land use for mining activity. Jaime Gutierrez Núñez, president of CAMIMEX responded that the companies affiliated to said organization do not oppose to the consultations on land use for mining activity, but emphasized that times should be established for conducting such consultations. Likewise, the Director of CAMIMEX, Karen Flores Arredondo stressed that “the rules of the game” must be clear and based on the General Consultation Law.
  • Miguel Ángel Riquelme Solís, governor of Coahuila State and Grupo Mexico signed an agreement to regularize properties in the Carboniferous Region of Coahuila. This regulation agreement represents legal certainty for more than 400 families in the Carboniferous Region.
  • The Mining Commission of the State Congress was installed, chaired by the deputy for Morena, Próspero Valenzuela Muñer to meet the demands and open a space for dialogue with the mining sector in Sonora. In that sense, he mentioned that it is important that said commission lays the foundations for the detonation of economic development and well-being in Sonora, taking advantage of the fact that this entity constitutes one of the main mining states in the country.
  • Octavio Alvídrez, CEO of the Mexican precious metals Fresnillo plc stated that mining in Mexico currently has an “unfavorable” environment due to recent government policies. President Andrés Manuel López Obrador has been criticized by the mining industry for his policy of not granting new concessions, as well as for what he has described as unprecedented regulatory delays. The president further fueled industry concerns by recently proposing to Congress a controversial energy constitutional reform that rejects concessions for Lithium.
  • The Mexican Geological Service (SGM) will invest MXP $55.2M between this year and the next in the exploration of lithium  with a view to finding an economically viable deposit, informed its director, Flor de María Harp. Exploration work will be carried out in 52 areas during 2021 and in another 30 in 2022. She explained that the country needs hard data so that we are not talking about what we believe, imagine or assume, but about data that have a technical basis. The official insisted that in Mexico expectations have been generated around lithium that is not real, because there is still no hard data on the potential of the mineral.
  • Karen Flores, director of the Mining Chamber of Mexico (CAMIMEX) stressed that due to lack of mineral concessions the mining industry in Mexico loses USD $25B with the consequent absence of jobs generation and the fiscal contribution. So far in this six-year term, no new concessions have been granted, in addition to the fact that there are procedures stopped that have also impacted on the continuity of some mining projects.
  • Sergio Almazán, president of the Association of Mining Engineers, Metallurgists and Geologists of Mexico (AIMMGM), highlighted the relevance of the mining industry for the country’s economy in the inauguration of the XXXIV International Mining Convention in Acapulco. CAMIMEX, in its 2020 report stated that the industry currently generates around 408,000 direct jobs, plus almost 2 million indirect jobs. It means that many Mexican families literally live from mining. Mining activity stands out as the fifth earner of foreign currency to the country. He also highlighted that Mexican mining is a formal, modern, sustainable, safe, fiscally responsible industry, with competitive salaries and high quality standards.

ON EXPLORATION

The Mining and Exploration News in Mexico: Highlights on the Fifth Week of September, 2021

By Jorge Cirett

During the 39th week of the year (September 27th to October 3rd, 2021), at least 20 press releases were announced by companies working in Mexico. To note, six companies posted exploration advances on their properties, one on financing and five more on project development or resource definition and one more on corporate matters. ON MEXICO ISSUES, Mexico’s government is looking for a law firm to represent its interests in international arbitration processes. A constitution amendment was proposed by the presidency of Mexico, to restrict the work of the private industry in the energy industry and to exclude private companies from the mining of lithium.   ON EXPLORATION, In Baja, One World Lithium is drilling at Salar del Diablo. In Sonora, Benjamin Hill Mining released assays from surface samples at the Benjamin Hill property. In Durango, Silverton Metals commenced exploration at the Pluton project; Silver Wolf Exploration released surface sample results for the Ana Maria project. In Zacatecas, Defiance silver is to start drilling the Lucita area on the Zacatecas project. In Oaxaca, Madoro Metals released radiometric ages on its Yautepec project.   ON MINING, No relevant news. ON FINANCING, Inomin closed a non-brokered private placement for $402.3 K in gross proceeds. ON RESOURCES AND DEVELOPMENT, GoGold Resources resources released drill results from the Mololoa area at its Los Ricos North project in Jalisco. Fabled Silver informed on drilling at its Santa Maria project in Chihuahua. Discovery Silver presented results from drilling at Cordero, in Chihuahua. Silver Dollar presented an update on La Joya, Durango. Silver Viper Minerals provided an update and drilling results from La Virginia, in Sonora. ON DEALS AND CORPORATE ISSUES, Altaley Mining engaged a group of consulting firms for financial publishing services and digital marketing services. ON SOCIAL RESPONSIBILITY, Capstone Gold informed on funding provided for sports in Zacatecas.

ON MEXICO ISSUES

  • Mexico’s government is looking for a law firm to represent its interests on international arbitration lawsuits, like the one brought by First Majestic Silver in the mining sector and Finley Resources, MWS Management and Prize Permanent Holdings on the oil services sector. Other relevant players that can initiate arbitration processes include Coeur Mining, AMERRA Capital Management, CMSA B. V., Contecon Manzanillo, Dal-Tile International, Doups Holdings, Gonzalo Mora Velarde and Jinlong Dongli Minera Internacional.

By Miguel A Heredia

During the 24th week of the year (June 14th to June 20th, 2021), at least 15 press releases were announced by companies working in Mexico and 6 news published by the media, with seven reporting on resources and developments, five informing on exploration results, four commenting on Mexican issues, two announcing financial rounds, two discussing social issues, and one disclosing deals and corporate issues.  ON MEXICO ISSUES, Dhipna Yanssen Weichselbaum, head of the Federal Programs in Baja California explained that 12,000 people will be consulted in Mulegé to carry out the consultation of El Boleo. The Argentine Embassy in Mexico along with the Ministry of Mining of that country carried out a working seminar with the Mexican company Baluarte Minero (Industrias Peñoles and Fresnillo PLC). The consultation for the nationalization of lithium, proposed by President Andrés Manuel López Obrador, is not necessary, since, it is already owned by Mexico. ON EXPLORATION, In Sonora, Tocvan and its JV partner Colibri reported drill results from its the El Pilar project, and Tarachi started a second drilling program on its San Javier mining concession at La Colorada gold bearing breccia pipe. In Chihuahua, Mammoth reported results from an additional 1.7km of 3D geophysical modeling conducted at its Tenoriba project. In Nayarit, Sierra Madre provided an update on the activities developed at its Tepic project. ON MINING, no relevant news. ON FINANCING, Azucar granted stock options to certain directors and officers of the company (El Cobre project, Veracruz). Advance Gold closed a private placement financing for gross proceeds of $200K (Tabasqueña project, Zacatecas). ON RESOURCES AND DEVELOPMENT, Almaden completed a surface induced polarization geophysical (IP) program at its Ixtaca project in Puebla. GoGold released results from eight drill holes collared at its Los Ricos project in Jalisco. Silver Viper filed on SEDAR a NI 43-101 technical report supporting the maiden mineral resource estimate for its La Virginia project in Sonora.

  • VanGold Mining Corp., provided initial results from its ongoing diamond drill program at its El Pinguico project in Guanajuato.  Eight holes were drilled of which the two first holes were collared outside of the mine in the patio of the portal of adit 4. These holes were not intended as traditional exploration holes. Holes P21-01 and P21-02 were collared to test the purchased rig but encountered noticeable visible vein material, which the company now interprets to be extensions of the San Jose vein. A third hole, P21-03, was collared to test the area for further vein extensions, and intersected several intervals of significant gold and silver values, including 0.38 g/t Au and 88 g/t Ag (116 g/t AgEq) over 4.05m, including 1.5 g/t Au and 122 g/t Ag (242 g/t AgEq) over 1m, plus an additional higher-grade interval of  2.11 g/t Au and 505 g/t Ag (674 g/t AgEq) over 0.55m. The rig was moved into El Pinguico mine where the company drilled holes P21-05 to P21-08. Holes P21-05 and P21-06 intercepted   long sections of alteration crossing both San Jose and El Pinguico veins but only moderate widths of moderate Ag-Au values were encountered.  Hole P21-07 encountered quartz and carbonate material of an unknown vein and at the San Jose contact the hole intercepted broken, unconsolidated material (approximately 35% recovery) and a void causing to abandon the hole. Hole P21-08 encountered numerous intervals of good grade material, being the most significant one returning 8.81 g/t Au and 208 g/t Ag (913 g/t AgEq) over 0.75m. Four additional holes (P21-09 to P21-12) were drilled from San Jose Cross Cut #1 but assay results are pending.
  • Silver Viper Minerals Corp., released a maiden Au-Ag mineral resource estimate at its la Virginia project in Sonora.   El Rubi Zone contains an indicated resource of 6,179,000 tonnes of 0.78 g/t Au and 35 g/t Ag for 154.3K Oz Au and 6.93M Oz Ag, and inferred resources of 3,255,000 tonnes of 0.9 g/t Au and 36 g/t Ag for 94.1K Oz Au and 3.75M Oz Ag in open pit category.

ON MEXICO ISSUES

  • The Ministry of Economy issued an informative note to correct what President López Obrador said about the expansion of the operations of the mining company El Boleo that operates in Baja California Sur. The mining and metallurgical company is seeking an expansion in the surface of its operations and not a new concession as stated by the president. In July 2019, El Boleo requested an expansion of its environmental impact statement, in which it requested an expansion of its mine by 446 hectares contiguous to its current operation. They indicated that this is because the life of the main mine is running out and its mineral reserves are in this adjoining land. The statement indicates that the mining project began construction in December 2010, with an investment of USD $1,717M, and began production in 2015. The company produces copper, cobalt, zinc and manganese. Currently, the mining company employs 1,282 direct jobs (836 unionized and 446 trusted).
  • Fernando Alanís, president of the Mining Chamber of Mexico (Camimex), stated that the mining industry in Mexico paid MXP $30,374M in taxes during 2020. He also highlighted that those that refer to the fact that the industry pays little are myths, as he highlighted that around 10.6% of the Gross Domestic Product generated by the industry is destined to the payment of taxes, higher than the 7.6% of the manufacturing industry, or the 6.1% of the electricity sector. Fernando Alanis detailed that of the total taxes paid, MXP $24,205M are for Income Tax (ISR), while there are MXP $2,576M in surface rights and MXP $3,593M in new rights.
  • The Mining Chamber of Mexico (Camimex) stressed that mining is a tractor industry that, in addition to boosting the regional economy, supports the development of other economic activities. It drives construction with average annual investments of USD $5B a year. The same occurs with the transport of materials, by promoting the movement of 8.7M tons per year that travel 100.2million kilometers on the roads (78%) and railways (22%) of Mexico. It also boosts port activity, with the export and import of 474M tonnes of materials per year. In total, the transportation costs of mining companies in Mexico total USD $245M per year. Through the mining clusters (Zacatecas, Sonora, Chihuahua, Guerrero and Sinaloa) a local supply has been developed that amounts to 9,700 national supplier companies, 90% of which are small and medium-sized enterprises (SMEs). For Mexico, the mining industry is an outstanding generator of income, contributing 8.3% to the industrial GDP and 2.5% to the national GDP. It is also a large generator of jobs, with more than 379,000 direct jobs and almost 2 million indirect jobs.
  • The Mexican mining industry called on the environmental authorities to hold a dialogue to understand the reasons why the permits are being stopped and to work together to unlock authorizations for Environmental Impact Manifestations (MIAs) that are being held at the Ministry of the Environment and Natural Resources which have stopped several mining projects in the country. Mining in Mexico has a robust environmental legislation that is permanently addressed, among which the General Law of Equilibrium and the Environmental Protection, as well as seven Official Mexican Standards and the general regulation that exists for activity in protected natural areas in Mexico, among others.
  • Representatives of the Mexican Mining industry asked the federal government to reactivate mineral concessions to increase investments in the sector. No new mining concessions have been granted in the country since 2019 and the effects of this were reflected in a lower Foreign Direct Investment in the sector.
