ON MEXICO ISSUES

  • Hermosillo, the capital city of the Sonora State, hosted the 14th International Mining Congress during October 18-21, 2022, with the participation of over 5,000 people.
  • The Mexican Mining Chamber (CAMIMEX) warned that thefts of output and goods like explosives in the mining industry continue to increase despite the support provided by the Secretary of National Defense (SEDENA). The General Director of CAMIMEX, Karen Flores, said that thefts remain a recurrent issue in the sector and highlighted that these crimes are probably perpetrated by organized crime.
  • According to data from the Ministry of Economy, the Mining Chamber of Mexico (Camimex) and experts, there is a mining collapse in Mexico since 822 mining projects were postponed, 180 foreign capital firms have left the country and there are 25 concessions stopped. If the policy were to change, 30% more jobs would be created and the contribution to Mexico’s GDP would increase by 0.5%, according to estimates. Mining and metallurgical activity exceeded tourism by 19% in foreign exchange generation. The president of the Association of Mining Engineers, Metallurgists and Geologists of Mexico (AIMMGM), indicated that the uncertainty generated by this administration in the sector has caused a slowdown, which has left investments far from the more than USD $8 billion that were reached in previous years. GoGold Resources Inc., and GR Silver Mining Ltd., reported the best drilling intercepts in Mexico on the third week of October, 2022. Details are shown in the table below:

ON MEXICO ISSUE

  • Colibri Resource Corporation and Oroco Resource Corp., reported the best drilling intercepts in Mexico on the fourth week of August, 2022. Details are shown in the table below:
·        The government of Mexico announced, through a decree in the Official Gazette of the Federation, the creation of the state company Litio para Mexico (LitioMx). The Government of Mexico created LitioMx as a decentralized public organism of the Federal Public Administration and coordinated by the Ministry of Energy, with its own legal personality and assets and with technical, operational and management autonomy. The objective of LitioMx will be the exploration, exploitation, benefit and use of lithium, located in national territory, as well as the administration and control of the economic value chains of such mineral.
·        According to the Mining Chamber of Mexico (CAMIMEX), a total of 822 mining projects remain on hold and represent an amount of USD $959M, which are still waiting for better conditions to be able to reactivate. Jaime Núñez, president of CAMIMEX stated that is essential to encourage exploration since unfortunately in the last seven years we have seen a decrease in investments in exploration, leaving several projects on standby.
·        Jaime Gutierrez Núñez, president of CAMIMEX stated that small-scale coal mining is like “the blood diamonds” of Africa, and that the Federal Electricity Commission (CFE) should certify where the mineral it buys comes from and its conditions.
·        Mexico’s mining industry plans to invest USD $5.5B in 2022, 15.2% more than in 2021, but according to the Mexican Mining Chamber (CAMIMEX), it will remain below the record figure of USD $8.04B seen in 2012 amid difficult conditions. Growing security problems, a high tax burden and the government’s decision to stop granting concessions for projects have prevented investments in the sector from increasing faster, said CAMIMEX head Jaime Gutiérrez.
·        Mining in Mexico grew by 7.1% in 2021 despite friction with the government. According to CAMIMEX’s annual report, this increase positioned it as the only productive activity that recovered and even exceeded the fall of 2020, when the covid-19 pandemic initially stopped its operations because the government did not consider it “essential activity”. Even without tax incentives, the mining sector presented an increase in its contribution to the gross domestic product (GDP) going from 2.3% in 2020 to 2.5% in 2021, and an annual advance in the proportion of industrial GDP from 8.3% to 8.6% in the same period.
·        The Governor of Durango, José Rosas Aispuro, considered unfair that the mining-metallurgical sector is one of the economic sectors with the highest tax burden in the country, even though it is an enabler that prevents the migration of people in the communities where it develops its production processes, for job creation and social benefits. Mining Entrepreneurs stated that mining generates jobs and is one of the industries that pays the most taxes, since in 7 years it has contributed more than MXP $240,000M (approximately USD $12B) in taxes and other rights.
·        In Mexico there are more than 1,209 mining projects that have been developed in 26 states of the Republic, in which 406,179 jobs have been generated and a production value that already exceeds MXP $334,782M (approximately USD $16.7B). Among the main minerals extracted from these deposits are gold, copper, silver, zinc, iron, molybdenum, lead, fluorite, among others. For its exploration and exploitation, in 2021 alone, investments have been made for more than USD $4,810M and more than USD $5,538M are expected by the end of 2022. Of the 1,209 mining projects that exist in Mexico, 286 are in Sonora, Chihuahua has 160 and Durango has 128, which positions them as the entities with the greatest economic benefit thanks to mining concessions. Of the total number of projects, 749 correspond to precious metals; 180 to polymetallic minerals, 167 to copper, 71 to iron ore and the remaining 42 to other metals and minerals. According to the Mexican Mining Chamber (CAMIMEX), there are currently a total of 263 projects in the exploration stage, 76 in production, 39 in the development stage, while 822 projects are being postponed and 9 operations are reported as closed. However, the agency assures that, since the start of the current administration, the federal government has stopped granting permits or concessions for the exploration and development of new projects, since so far more than USD $959.7M dollars have not been invested. .

ON MEXICO ISSUES

  • Vizsla Silver, GR Silver and Defiance Silver reported the best drilling intercepts in Mexico on the second week of August, 2022. Details are shown in the table below:
  • According to a report from the Secretariat of Labor and Social Security, in the last three years, 979 mine inspections have been carried out throughout the country, of which 387 have been carried out in the coal zone, which means that “39% of all the mining inspections that have been carried out in the coal zone of Sabinas (Sabinas, Nueva Rosita, Palau)”. In the coal region, in these three years, 27 mining operations have been closed; that is, 84% of all mine closures in the country, due to non-compliance with security measures; to date 15 remain in force. In addition, the Ministry of Economy has been informed of the existence of 12 concessions that presumably could have irregularities.
  • The General Directorate of Mines of the Ministry of Economy provisionally suspended the works on 10 mining concessions in Sabinas Coahuila, on August 11, until the employers or representatives of each of the work centers certify compliance with the measures dictated in each one of the respective files after the inspections carried out by the Ministry of Labor and Social Security (STPS). The then General Director of Mines did not proceed with the provisional suspension of the works, arguing that the STPS information on the 10 previously mentioned mining concessions did not coincide with the registry data held by the General Directorate of Mines. Considering this and other possible irregularities, the Directors of Mines and Obligations were dismissed last June with the purpose of investigating and, where appropriate, establishing the corresponding responsibilities.

ON EXPLORATION

  • Monumental Minerals Corp., announced results of a recently satellite multispectral interpretation covering its Jemi Heavy Rare Earth Elements project in Coahuila. The interpretation highlighted discreet areas that may host eudialyte-bearing dykes, veins, and disseminations. Eudialyte is a Na, Ca, Fe/Mn, Zr silicate mineral that can contain up to 10% Rare Earth Elements, and 12% ZrO2. The Aster satellite spectral data also identified several areas prospective for Cu-Zn-Pb-Ag carbonate replacement deposits.

ON EXPLORATION

  • Silver Spruce Resources Inc. along with Colibri Resource Corp. completed its phase 1 drilling program at the 1,057 ha Diamante project in Sonora. The 2,005 m reverse-circulation program in 19 holes, up to 135 m in depth, covered the La Prieta, and Pillado targets. “Mineralization is reported visually as pyrite, arsenopyrite, chalcopyrite, sphalerite, argentiferous galena, argentite, hematite and probable metal oxides, carbonates and sulphates, including copper carbonate (malachite), copper sulphates and plumbojarosite”.
  • Vortex Metals Inc. provided an update in exploration of its Riqueza Marina and Zaachila projects in Oaxaca. The late David Jones identified this area in the early 2000’s …”Copper-gold mineralization within both the Riqueza Marina and Zaachila projects is associated with geologic processes operative in the Late Jurassic to Middle Cretaceous within a back-arc sequence of bi-modal volcanics and volcaniclastics deposited on the sea floor. Early exploration conducted by Dave Jones identified several copper and gold anomalies over a broad area but clearly associated with specific rocks, i.e. exhalite, rhyolite debris aprons or breccia. These associations prompted the identification of a geologic environment which incorporated these features. The Volcanogenic Massive Sulfide (VMS) model incorporates the geologic and geochemical features observed to date”.
  • Kootenay Silver Inc. informed significant progress has been made on the 15,000 m drilling campaign at Columba, in Chihuahua. The current program will test extensions of the F, D, B and JZ veins and exploratory step-outs on other prospective veins. The V vein has been traced for over 700 m of strike and 200 m of depth with an average of 2 m in width, the D vein has been hit along 430 m of strike and 340 m of depth with an average of 6.9 m in width.

ON MEXICO ISSUE

  • Great Panther Mining Limited announced that it has begun the closure process at its Guanajuato facility. Great Panther issued a statement announcing the gradual closure of activities, due to not having the respective permit to expand tailings storage in the Jolula Dam, which is part of the mining complex. According to Great Panther, the permit was requested to the National Water Commission (CONAGUA) but so far it has not been authorized. For that reason the company cannot continue operating; but the operations will return, once they receive said authorization. The activities will continue solely for the care and maintenance of facilities. The mines that will be shut down are San Ignacio, the Guanajuato Complex and the Jolulaprocessing plant, located in the former Hacienda de Bustos, also known as ‘Cata’. Mine workers have expressed concern about the situation because when the activities stop in the mines in which they work they will lose their economic income. The precise data on how many employees will be affected by the situation is not yet available.

ON EXPLORATION
