Quartz veining hosted in a hydrothermaly-altered intrusive

By Miguel A Heredia

During the 18th week of the year (May 1st to May 7th, 2023), at least 28 press releases were announced by companies working in Mexico, and 2 news published by the media, with eleven reporting resources and developments of their properties, six commenting on Mexican issues, four communicating production and financial results, three disclosing deals and corporate issues, three announcing financing issues, two informing on exploration results, and one discussing social issues. ON MEXICO ISSUES, Fortuna Silver reported an illegal blockade at its San Jose mine in Oaxaca. At least 40 companies from Canada and the United States that operate in Mexico expressed their intention to protect themselves after the approval of the reforms to the Mining Law. Chesapeake has initiated legal proceedings against the Dirección General de Minas of Mexico (DGM) with the Federal Court of Administrative Justice in the state of Durango, Mexico in response to the DGM’s cancellation of the San Vicente 3 mineral concession. Radius filed a legal demand with a Federal Mexican Court to obtain title to the Amelia 4 mining concession at its Amalia project in Chihuahua. The Senate of Mexico approved the mining reform that reduces and facilitates the cancellation of concessions. Bendito Resources, Infinitum Copper, Pan American Silver, and Silver Tiger reported the best drilling intercepts in Mexico on the first week of May, 2023. ON EXPLORATION, In Sonora, Infinitum Copper reported results from 6 of 12 drill holes collared at its Adelita project. In Chihuahua, Reyna Silver provided an update on their Batopilas and Guigui projects.  ON MINING, Capstone, Argonaut, and First Majestic reported Q1, 2023 production and financial results for their Mexican operations. Minera Alamos reported full year 2022 production and financial results from its Santana property in Sonora.  ON FINANCING, Sonoro Gold announced it plans to undertake a non-brokered private placement for gross proceeds of up to CAD $3M (Cerro Caliche project, Sonora). Kootenay announced a private placement for gross proceeds of $4M (Columba project, Chihuahua). First Majestic announced that its Board of Directors has declared a cash dividend payment in the amount of $0.0057 per common share for Q1, 2023. ON RESOURCES AND DEVELOPMENT, Xali received the change in soil use permit for its El Oro Tailings project in Mexico State.

Tarachi signed a definitive agreement for the sale of Magistral Tailings project in Durango.  ON SOCIAL RESPONSIBILITY, Almaden completed a social impact assessment relating to its Ixtaca project in Puebla, and underlying mineral claim area.

ON MEXICO ISSUE

  • Fortuna Silver Mines Inc., reported an illegal blockade at its San Jose mine in Oaxaca due to a group of workers did not agree with the estimated amount the Company is to distribute among the workforce as part of the worker´s profit sharing entitlement. Profit sharing is a transparent calculation and is payable in accordance with Mexican legislation.  As a consequence, operations at the mine have been temporarily halted.
  • At least 40 companies from Canada and the United States that operate in Mexico expressed their intention to protect themselves after the approval of the reforms to the Mining Law by the government because they consider that they are violating their rights and that they are being changing the rules of the game. The law firm Von Wobeser y Sierra, anticipated that they will also consider the international arbitration considered as a mechanism to resolve disputes within the framework of the Free Trade Agreement between Mexico, the United States and Canada (T-MEC) and the Trans-Pacific Economic Cooperation Agreement (TPP). The elimination of the concepts of Free Land and First Applicant are the elements that most concern companies because with them the government could “legalize” the non-granting of concessions to private parties, by giving the exploration monopoly to the Mexican Geological Service (SGM). ), warned the Mining Chamber of Mexico (Camimex). Until now, the Canadian mining company Silver Bull Resources presented in March to the International Center for Settlement of Investment Disputes (ICSID) its intention to claim economic damages for at least USD $178M for the blockade of its Sierra Mojada Project since September 2019. The American Vulcan Materials presented to ICSID a claim for an estimated damage of at least USD 1.9 B against Mexico for the closure and occupation of the Sac-Tun mine (formerly Calica) and the Punta Venado pier in Playa del Carmen. A resolution on this issue is pending since May 2022.
  • Chesapeake Gold Corporation has initiated legal proceedings against the Dirección General de Minas of Mexico (DGM) with the Federal Court of Administrative Justice in the state of Durango, Mexico in response to the DGM’s cancellation of the San Vicente 3 mineral concession, on the basis that the Company did not provide adequate evidence to support the Company’s performance of the exploration work required to maintain the concession. The Company’s legal position, approved by external Mexican legal counsel, is that the work required to maintain the concession was conducted on the property and appropriate evidence was submitted to the DGM to substantiate the work. The San Vicente 3 mineral concession is one of 12 mineral concessions comprising the Metates property, representing 700 hectares of the 4,260 hectares in the Metates project, and encompasses a portion of the Metates mineral resource. The Company intends to vigorously defend its position with respect to the San Vicente 3 mineral concession.
  • Radius Gold Inc., filed a legal demand with a Federal Mexican Court to obtain title to the Amelia 4 mining concession at its Amalia project in Chihuahua. “Radius and project JV partner Pan American Silver Corp. have completed all the requirements, fee payments and surveys for the Amalia 4 application.  The mining authority of Chihuahua has processed and approved the submission without fault and passed the license to the Mexico Mining Directorate proposing title issuance.  The regulated time for the mining authority to comment and request revision has passed and granting of title is a legal requirement under the mining law.  Radius has filed a legal demand to enforce the granting of title.  Radius legal counsel believes the Company has clear legal right to the application and title.  Legal counsel has been successful in obtaining granted concessions in similar situations recently”.
  • The Senate of Mexico approved the mining reform that reduces and facilitates the cancellation of concessions. The legal changes were approved despite Canada’s claim and in an express session in which twenty laws and reforms were endorsed in just five hours.  The senators approved modifications to the Mining, National Water, General Ecological Balance and Environmental Protection laws, and the General for the Prevention and Integral Management of Waste. The reform will allow the government to only grant mining concessions through a public tender and with prior consultation with indigenous peoples, in addition to facilitating the revocation of the license for environmental damage. The reform could generate tensions with the partners of the T-MEC, in particular with Canada, which has already complained in recent days. The Canadian Minister of International Trade, Mary Ng, revealed last Wednesday that she spoke with the Secretary of the Economy of Mexico, Raquel Buenrostro, to express the “concern” of the Canadian government with the then proposed reform of the country’s mining sector, in the that Canadian companies constitute the largest foreign investor.

ON SOCIAL RESPONSIBILITY

  • Almaden Minerals Ltd., completed a social impact assessment  (SIA) relating to its Ixtaca project in Puebla, and underlying mineral claim area, and the completion of a human rights impact assessment (HRIA) that examines the potential impacts that could be caused if the Ixtaca project is developed in a manner consistent with the Ixtaca Feasibility Study. “The SIA concluded that there were no elements identified that would justify the cancellation of the concessions so long as the necessary social management measures were in place to avoid, mitigate or compensate for the potential negative impacts and amplify the positive ones. The HRIA represents a much more significant and holistic study than the SIA, as it aims to predict, identify, characterize, and assess the potential positive and negative impacts that the Ixtaca project could have during its lifespan on the human rights of both indigenous and non-indigenous communities located within its areas of influence and on other identified project stakeholders. In the event potential impacts are identified, the HRIA proposes strategies to amplify the positive and mitigate or compensate for the negative”.

The Mining and Exploration News in Mexico: Highlights on the Fourth Week of April 2023

/ Gambusino Prospector / Leave a comment

By Jorge Cirett                                             

During the 17th week of the year (April 24th to April 30th, 2023), 17 companies working in Mexico released news on their work. Five companies informed on exploration on their properties, six companies informed on Q1 2023 or full-year 2023 production/financial results. Two companies announced the closing and opening of financing rounds. A company corrected assay information on a previously issued drill intercept; one other provided an update on its intention to sue the Mexican government under a NAFTA legacy claim regarding the lack of action to terminate an illegal blockade. ON MEXICO ISSUES, Canada’s ministry of International Commerce, Mary Ng, expressed the preoccupation of foreign investors on the incoming changes to the Mining Law. The Mining Law was passed on Saturday morning by the Senate, and is set to return discretionary powers to the State on mining concessions. ON EXPLORATION, in Sonora, Prismo Metals released assays from surface sampling at its Los Pavitos property; Regency Silver released good results from deep drilling at its Dios Padre project; Colibri Resource released results from drilling at Evelyn project. In Zacatecas, Radius Gold updated on exploration work at the Tropico property. ON MINING, Sierra Metals, Mag Silver, Santacruz Silver, Alamos Gold, Pan American Silver and Agnico Eagle released Q1 2023 production reports. ON FINANCING, Silver Viper closed a private placement for $3.3 M; Radius Gold is to raise $1.75 M. ON RESOURCES AND DEVELOPMENT, Oroco Resource corrected assay results from one hole, previously issued last week, from its Santo Tomás project in Sinaloa. ON DEALS AND CORPORATE ISSUES, Guanajuato Silver informed on managerial changes. Silver Bull is to sue the Mexican government if a deal is not reached on an incoming meeting regarding the lack of action by the government to terminate an illegal blockade on its Sierra Mojada project in Coahuila. Prismo Metals and Vizsla Silver formalized the joint technical committee to oversee exploration of the Panuco district in Sinaloa, with Peter Megaw, Craig Gibson and Jesus Velador as members. ON SOCIAL RESPONSIBILITY, no relevant news.

ON MEXICO ISSUES

  • The ministry of International Commerce of Canada, Mary Ng, expressed to Raquel Buenrostro, head of the Economy Secretariat (Secretaría de Economía) the preoccupation of foreign investors on the changes to the Mining Law, and the negative implications on North America supply chains.
  • The Senate Commission on Regional Development and Legislative Studies approved without changes, by the ruling party coalition senators of Morena, PT, PVEM and PES parties, the reforms to the Mining Law, National Waters Law, Ecologic Equilibrium Law, Environment Law, and the General Law for prevention and Comprehensive Treatment of Tailings in Matter of Mining and Water Concessions. Among the changes is the reduction of mining concessions validity from 100 to 80 years (under certain conditions), the instauration of an auction system by the government for mining concessions, establishing that the concession title is to be issued AFTER the environmental, labor, energy, social and any other federal permit needed have been received (Note by Editor. – Speaking of putting the cart before the horse).
  • On the changes to the Mining Law. (Note by editor) The reform to the Mining Law is directed to regain quasi absolute control of mining concessions by the government, establishing rules under which the concessions can be revoked on grounds of indigenous population, community issues, environmental issues and water scarcity, all on which the government plays the role of judge and party. This is part of a broader drive by the president to concentrate power in himself and his government coalition before the 2024 presidential elections.

ON EXPLORATION

Copper mineralization (chrysocolla)

By Miguel A Heredia

During the 16th week of the year (April 17th to April 23th, 2023), at least 17 press releases were announced by companies working in Mexico, and 8 news published by the media, with nine commenting on Mexican issues, six communicating production and financial results, four reporting resources and developments of their properties, four disclosing deals and corporate issues, one informing on exploration results, and one announcing financing issues. ON MEXICO ISSUES, Minera Gorrión, a subsidiary of Almaden Minerals, will challenge the cancellation of their concessions in the Municipality of Ixtacamaxtitlan, Puebla. Municipal Presidents (Majors), as representatives of the mining communities of the Chihuahua State, signed and sent a letter to AMLO to request that the Mining Reform initiative be analyzed, since they consider that it will seriously affect employment, health, education, local businesses, and in general, the well-being of the population. The Association of Mining Engineers, Metallurgists and Geologists of Mexico (AIMMGM) requested to expand discussion on mining law before submitting its vote in the Senate. The Plenary of the Chamber of Deputies, with the rejection of the opposition, started the debate that ended in the approval, in “fast track” of a new Mining Law, at the initiative of the parliamentary group of Morena. According to specialists, the Reform to the Mining Law would affect fundamental rights and international treaties, opening an USMCA panel with Canada. With 290 votes in favor, 186 against and one abstention, Morena and his allies in the Chamber of Deputies got ahead of the opposition and approved in plenary session an alternative initiative to that of President Andrés Manuel López Obrador that reforms the Mining Law and other arrangements. Mining companies lose on the Mexican Stock Exchange due to the initiative to reform the Mining Law in Mexico. GoGold and Oroco reported the best drilling intercepts in Mexico on the third week of April 2023. ON EXPLORATION, In Oaxaca, Vortex received community approval for environmental and surface geological surface baseline study at its flagship Zaachila project.  ON MINING, First Majestic, Golden Minerals, Avino, and Guanajuato Silver, reported Q1, 2023 production and financial results from their Mexican mine operations.

ON MEXICO ISSUE

  • Minera Gorrión, a subsidiary of Almaden Minerals Ltd., will challenge the resolution of a judge of the second court district in the state of Puebla to cancel their concessions in the Municipality of Ixtacamaxtitlan, Puebla, avoiding developing open-pit mining projects. Minera Gorrión regretted the resolution to cancel its concessions in Puebla, since it does not include any argument that the company provided in its defense. The company said in an statement that  it is important to clarify that, as long as the legal proceedings related to this case continue, the company’s concession title requests remain valid, thus preserving the company and its acquired rights. For more than 20 years, the company has invested more than MXP $900M in exploration, the identification of a mineral deposit, and the planning to develop a modern mining project, which will have a very significant economic impact if authorized. “Minera Gorrión regrets that, in his resolution, the judge does not include any of the arguments that the company provided to defend its case.
  • Municipal Presidents (Majors), as representatives of the mining communities of the Chihuahua State, signed and sent a letter to AMLO to request that the Mining Reform initiative be analyzed before it is approved by the Congress since they consider that it will seriously affect employment, health, education, local businesses, and in general, the well-being of the population.
  • The Association of Mining Engineers, Metallurgists and Geologists of Mexico (AIMMGM) requested to expand discussion on the draft Decree for the reform of the Mining Law, the National Water Law, the Law of Ecological Balance and Environmental Protection and the General Law for the Prevention and Integral Management of Waste related to Mining and Water Concessions before submitting its vote in the Senate.
  • The Plenary of the Chamber of Deputies, with the rejection of the opposition, started the debate that ended in the approval, in “fast track” of a new Mining Law, at the initiative of the parliamentary group of Morena. Deputy Ignacio Mier Velazco, coordinator of the Morena Parliamentary Group said that “for the first time it is regulated, transparency is given, the people of Mexico are given certainty, the environment is protected and the water is taken care of”. However, during the discussion in general, the opposition showed their rejection of the approval of this law, for not listening to the voices of indigenous people, peasants, or defenders of the environment. The deputy Laura Patricia Contreras Duarte (PAN), assured that the initiatives proposed by the President of the Republic are nothing more than “whims”.
  • According to specialists, the Reform to the Mining Law would affect fundamental rights and international treaties, opening an USMCA panel with Canada. The mining and water reform initiative, which is under discussion in Congress, has generated concern in various sectors due to the possible violations of fundamental rights that its entry into force could imply, said lawyers who are experts in the matter. One of the aspects that have been the subject of criticism is the elimination of requests for processing of new concessions that are pending resolution.  The initiative is a very serious impact on foreign direct investment, since it generates great discontent in the foreign mining sector, especially Canada, which belongs to the USMCA. As a result of this, it is very likely that a dispute resolution panel will be initiated because it is a clear violation of Mexico’s obligations in the protection of foreign investment, noting that Canadian investment is very large in Mexico, so it is a direct affectation to their interests.
  • With 290 votes in favor, 186 against and one abstention, Morena and his allies in the Chamber of Deputies got ahead of the opposition and approved in plenary session an alternative initiative to that of President Andrés Manuel López Obrador that reforms the Mining Law and other arrangements. The proposal -voted only in general and which is still being discussed in particular- reduces the validity of mining concessions from 50 to 30 years, with the possibility of extending them for another 25 years and at the end of that term, in case of participating in the new tender of the same lot, the holder would have preference for another 25 non-extendable years. In what the opposition described as an “albazo”, the parliamentary majority of Morena resumed the presidential initiative on the matter and presented it as its own initiative to discuss and vote on it on “fast-track”. It also conditions the mining concession to water availability and, where appropriate, to the mining water concession previously obtained, in accordance with the spirit of the Constitution in this matter, which gives priority to the human and domestic use of water. The obligation of the concessionaires to carry out the efficient use and reuse of water and, where appropriate, the restoration of the water resource is established. In its reform proposal, the Federal Executive proposed that the concession only be granted for mineral or substance susceptible to exploitation, which will allow, in its opinion, greater control and generation of resources for the State and the affected communities. In another aspect, the federal government establishes in its proposal that acts of private law are not recognized for the transfer of the mining concession, so that the Ministry of Economy may authorize the transfer only when the requirements requested for the original concession are met. That is, the concession will not serve to guarantee the obligations of the concession holder. On this, the initiative of the Morena legislators establishes that the transmission and guarantee of mining concessions will be carried out with the authorization of the General Directorate of Mines of the Ministry of Economy, as long as it is verified that the transmission is between two mining companies, in order to avoid speculation. In the case of the guarantee, when it is a company that is in operation. In order to regulate and avoid predatory, harmful mining activities that are contrary to the right to water, a healthy environment, people’s health and, in general, the rights of the towns and communities where said projects are carried out, the initiative of the Executive proposes presenting a social impact study and a Restoration, Closing and Post-closing Program. Likewise, it requires a Mine Closure Plan, the presentation of letters of credit to guarantee compliance with the mitigation and restoration obligations and a Waste Management Program. The initiative of the legislators considers the instrument of a letter of credit to guarantee the Mine Closure Plan.
  • Mining companies lose on the Mexican Stock Exchange due to the initiative to reform the Mining Law in Mexico. Grupo México, the main copper producer worldwide, fell 1.73%, to MXP $91.43 pesos per share, and Industrias Peñoles, the largest silver producer, lost 1.49%, to MXP $279.29 per share. The miners are concerned about the possible negative effects on their profitability and the economic impact on the country, since the proposal implies higher costs for them and a shorter time to recover the expenses,” said José María de las Rivas, Analyst at Intercam Bank.

/ Gambusino Prospector / Leave a comment

By Jorge Cirett                                             

During the 15th week of the year (April 10th to April 16th, 2023), 16 companies working in Mexico released news on their properties. One company informed on exploration at one of its properties, eight companies informed on Q1 2023 production results. One company closed a financing placement while a company opened another one. A company informed on the advance to take a property into production, one other reported drilling results at its main project. One company is exercising its option to acquire a property, while one other is extending the option on an exclusivity agreement. ON MEXICO ISSUES, calls for dialog with Congress are being made with urgency on the merits and negative implications of the proposed changes to the Mining Law. The federal government qualified Vulcan Minerals compensatory demand as unfounded. ON EXPLORATION, in Sonora, Tocvan Ventures provided results from a leach test at its Pilar property. ON MINING, Endeavour Silver, Guanajuato Silver Company, Fortuna Silver, Torex Gold, Gold Resource, Gatos Silver, Orla Mining and Bear Creek Mining released Q1 2023 production reports.

Radius Gold extended the exclusivity agreement term with Fresnillo PLC on its Plata Verde Project in Chihuahua. ON SOCIAL RESPONSIBILITY, no relevant news.

ON MEXICO ISSUES

  • On the proposed changes to the Mining Law. For the last two weeks there have been many declarations by mining industry members and representatives against many of the proposed changes. There is a widespread movement calling for open discussions of the many elements on this proposal that are to pose a grave threat to foreign and local investment on the industry, affecting a large population base and increased deleterious effects in the economy on the long run. The AIMMGM (Asociación de Ingenieros Mineros, Metalurgistas y Geólogos de México) is asking Congress to organize an open parliament on the subject to discuss the merits and negative implications of the proposed changes.
  • The Mexican federal government qualified Vulcan Minerals $1.9 billion compensatory demand as unfounded on its reply to Centro Internacional de Arreglo de Diferencias Relativas a Inversiones courtroom. Vulcan has been quarrying limestone in Quintana Roo for more than 30 years, and has been pointed by the government as the culprit of an ecological disaster.

ON MEXICO ISSUE

  • Silver Tiger Metals Inc., was the only mining company reporting drilling intercepts in Mexico on the first week of April, 2023. Details are shown in the table below:

ON EXPLORATION

  • Colibri Resource Corporation reported assay results of sampling completed at its recently acquired El Plomo project in Sonora. Twenty-five grab samples returned values > 1.0 g/t Au, including 6 with values > 5 g/t Au. “A total of 62 grab samples taken by Colibri returned Au assay values > 0.1 g/t Au. Channel sample values range from 8.03 g/t Au to 0.089 g/t Au over sample lengths (true widths) of 1.7m to 0.1 m. The occurrence and general distribution of higher-grade samples (> 1.0 g/t Au) evident in the historical work was validated with the due diligence sampling”.
  • Prismo Metals Inc., released assay for 277 samples taken at its Los Pavitos project in Sonora, from which 175 samples collected at the Santa Cruz area returned 0.5 g/t Au or more (several with values above 5 g/t Au over widths of 0.20 to 1m, and the best returned 20.3 g/t Au over 0.6m), and seven samples returned over 100 g/t Ag.  Pathfinder elements As and Bi are also generally strongly anomalous. “At least six other target areas have been identified for additional detailed work to develop drilling targets for later this year. Drilling permits are in process and drilling is expected to begin in Q2 2023”.
  • Kingsmen Resources Ltd., expanded its land position at its Las Coloradas project in the southeast part of the Parral mining district in Chihuahua, with the acquisition of a new claim. The new 342 hectares claim is adjacent to its Las Coloradas project and covers prospective geology and structural and geophysical targets.
  • Monumental Minerals Corp., reported assay results and proposed drill targets from its flagship Jemi rare earth elements project in Coahuila. The company has completed four months of exploration consisting of detailed geological mapping, regional stream sediment sampling, ground radiometric geophysical surveys, and lithogeochemical sampling. “A total of 296 assays have been received for surface rock chip samples from Jemi Dykes and Veladora North. Samples that are both peralkaline and anomalous in REEs, Ta, and Nb (116 samples) define four discreet priority areas within Monumental’s mineral concessions”. “Three-dimensional modeling of airborne magnetic data indicates that a larger intrusive body and potential source for the mineralized dykes may lie at a shallow depth (less than 300 m) beneath the dykes. Based on these results, six preliminary drill targets have been chosen and a drilling program is anticipated to commence in June 2023”.
  • Minaurum Gold Inc., provided an update on its corporate strategy to develop and acquire a pipeline of potential Tier One precious metals projects, through a portfolio containing silver projects totaling 37,928 hectares; gold projects totaling 25,933 hectares; and copper projects totaling 12,856 hectares. “Key initiatives for each flagship project include: underground rehabilitation to be followed by mapping, sampling and underground drilling at its Alamos Silver project in Sonora. Results will serve as a basis for an initial resource estimate; at Santa Marta Copper-Gold Project in Oaxaca, an initial drill program has been designed and is awaiting a drill permit from SEMARNAT, the Mexican federal environmental permitting agency; and at Aurifero Gold Project in Sonora, a drill program to test deep targets has been designed and drill permits have been applied for, actively working to further consolidate the district.  Minaurum expects to advance the remainder of its projects through strategic joint ventures in exchange for a combination of royalties, carried interests, and payments such as it received in option agreements with Fortuna Silver Corp. and Infinitum Copper Corp”.

ON MINING

  • GoGold Resources Inc., reported Q1, 2023 production results from its Parral Tailings project in Chihuahua. The company produced 173.7K Oz Ag, 2,106 Oz Au, and 320.3K Lb Cu (400.1K Oz AgEq).

ON FINANCING

  • Golden Minerals Company announced that it is selling gold-rich pyrite concentrates from its Velardeña properties on improved terms to a buyer in Manzanillo. The Company had previously planned to construct a BIOX facility at Velardeña in order to recover the gold in the pyrite concentrate. The Company is now evaluating the economics of a restart of the Velardeña operation without the need for major capital expenditures for the BIOX facility and ancillary equipment. Golden made its first shipment of 142 tonnes of previously produced and stockpiled gold-rich pyrite concentrate under the new terms last week and is currently processing 3,000 tonnes of previously mined and stockpiled mineralized material from the Santa Juana mine for future shipments.

The Mining and Exploration News in Mexico: Highlights on the Fifth Week of March 2023

/ Gambusino Prospector / Leave a comment

By Jorge Cirett                                             

During the 13th week of the year (March 27th to April 2nd, 2023), 18 companies working in Mexico released news on their properties. Two companies informed on exploration on their properties, three companies informed on Q4 and year 2022 financial and operational results. Two companies closed partial or complete share placements. Two companies filed technical reports on their properties, two more released drilling results on their advanced properties and two more updated mineral resource estimates for their properties. Two companies announced the completion of the acquisition process on mining projects. ON MEXICO ISSUES, the Mexican president sent an initiative to change the Mining Law that is likely to strongly impact the mineral exploration industry. ON EXPLORATION, In Sonora, Tocvan Ventures provided an update on bulk sampling at its Pilar property; Reyna Gold is to drill its La Gloria project. ON MINING, Mag Silver, Sierra Metals and Avino Silver released Q4 2022 financial reports. ON FINANCING, Silver Spruce closed a private placement for $1.13 M, Golden Tag closed the first tranche of a non-brokered private placement. ON RESOURCES AND DEVELOPMENT, Alamos Gold and Sonoro Gold filed NI-43-101 technical reports on the Mulatos and Cerro Caliche properties respectively, both in Sonora. GoGold Resources released drilling results from Los Ricos South project in Jalisco. Oroco Resource informed on drilling at the Santo Tomás project in Sinaloa. Argonaut Gold updated on mineral resources at five of its properties in Mexico. Aura Minerals reported on mineral reserves and resources at Aranzazu, in Zacatecas. ON DEALS AND CORPORATE ISSUES, Argonaut Gold completed the sale of the Ana Paula project in Guerrero to Heliostar Metals. Sierra Metals completed the acquisition of La Guitarra project, in Estado de Mexico, from First Majestic Silver. ON SOCIAL RESPONSIBILITY, no relevant news.

ON MEXICO ISSUES

  • The president of México, Andrés M. López Obrador sent to Congress an initiative to reform the Mining Law, National Water Law, Ecological Equilibrium Law and Environmental Protection and the General Law for Prevention and Integral Management of Residues relating to Mining and Water Concessions. The initiative displays a heavy ideological charge on the exposition of motifs, full of propaganda epithets against the “neoliberal” current state of affairs on these matters. Any good specific proposal within the initiative is overwhelmed by the sheer amount of new rules designed for the State to have a firm grip on the industry, many of which involve granting the government power to decide when to take away a concession on flimsy grounds, raising the uncertainty level for mining investment in Mexico. Some takeaway points that drastically change how the mining industry is operating in Mexico include: The government is to perform auctions for mining concessions (no more staking). Mining activities are no longer considered to have priority over other land uses. No land expropriation on mining grounds. Social impact studies to be conducted before any exploration takes place. Public consultations with “towns”, indigenous (which by the way are auto ascribed) and afro-Mexican communities. Reduction of mining concessions rights from 50 to 15 years, that could be renewed only once (more than a few operations in Mexico have been continuous for far longer periods). Mining concessions are conditioned to water “availability” (yes, the government decides, unconstrained, when there is available water, anytime). No private transmission of mining concessions without government consent (again, absolute power to the government). Added cancellation causes include lack of report in possible harm or risks to ecological equilibrium, lack of permits, concessions or authorizations from other authorities and lack of closing programs or management of residues. The only way to obtain a concession is to be by government auction (Concurso). Limits mining concessions coverage to only one element (you have to wonder on the genius that came with this proposal). The list continues, but in a first pass reading those above come as the most likely to cause an exodus of investment in mining exploration in Mexico. Mines are to continue operating, and advanced properties are likely to continue to development, but the Mexican exploration industry is about to halt when this initiative is approved, as the government has the required number of votes secured in Congress. Dialogue between industry entities and the government should take place before this initiative is voted, because better alternatives should be sought in order to achieve a better operating mining industry. Alternative options agreed upon should both improve the effect of mining operations in communities and the environment while promoting investment, thus helping Mexico’s development as a whole.         

ON EXPLORATION

  • Tocvan Ventures Corp. provided a progress update on the first bulk sample at the Pilar project in Sonora. Over 1,200 tonnes of material have been stockpiled with the first shipments completed. Four head-grade samples averaged 6.2, 7.6, 1.3 and 7.6 gpt Au. “Diagnostic leach tests are ongoing and were collected from four trench areas and one select drill core coarse reject sample. Preliminary results from the study suggest free gold is present in the samples and has been confirmed visually by testing sieved…. Up to 1,000 tonnes of oxide-gold material will be extracted from select areas….. The information provided from the sample will be used for planning in coordination for permitting of full-scale mine and process facilities on-site at Pilar”.
  • Reyna Gold Corp. announced the mobilization to recommence a minimum of 5,500 m of diamond drilling at its 24,215 ha La Gloria property in Sonora. The program is focused on four targets: La Republicana, Western, Las Carmelitas and Main Zone. At La Republicana drilling “will test extensions to the La Republicana Main Vein, which produced 59.00m of 1.45 g/t Gold in Phase 1 drilling”, on the 1 km long vein with significant anomalies delineated by an induced polarization survey. At Western, abundant quartz veining with Au-Te high-grades are to be tested. At Las Carmelitas high Cu, Ag, Sb assays have been obtained in a large conglomerate/agglomerate system. At the Main Zone, follow-up is to test on phase-1 drilling that returned 5.5 m @ 935 gpt Ag; 7.85 m @ 3.94 gpt Au; 30.60 m @ 0.51 gpt Au.

During the 10th week of the year (March 6th to March 12nd, 2023), at least 9 press releases were announced by companies working in Mexico, and 4 news published by the media with five commenting on Mexican Issues, three informing on exploration results, two reporting resources and developments, two disclosing deals and corporate issues, and one discussing social issues. ON MEXICO ISSUES, Peñoles and Fresnillo plc recognized the role of women in mining, commemorating his legacy from the beginning of his participation in this sector. In Mexico, women in mining have access to salaries up to 30% higher than the national average. According to figures from the Mexican Social Security Institute (IMSS), more than 66,000 women work in the mining-metallurgical industry, which is equivalent to 16.3% of the total workforce. Proposals to modify the Mining Law lack support, say experts, since the industry complies with at least 4,000 legal obligations, before starting operations of a mining unit. GoGold and Torex reported the best drilling intercepts in Mexico on the second week of March, 2023.  ON EXPLORATION, In Sonora, Aztec Minerals reported that it has commenced the 2023 exploration program at its Cervantes project. In Sinaloa, Prismo announced that it has received authorization for drilling its Palos Verdes project.  In Oaxaca, Vortex Metals provided an update on the environmental works it has conducted at its flagship Riqueza Marina project. ON MINING, no relevant news. ON FINANCING, no relevant news. ON RESOURCES AND DEVELOPMENT, GoGold reported additional drilling results from Los Ricos South, within the Eagle and Main Deposits in Jalisco.  Torex released results from the drilling program conducted at its Media Luna project in Guerrero. ON DEALS AND CORPORATE ISSUES, Guanajuato Silver announced that a new shareholder has acquired a significant equity position in the company (El Cubo, Valenciana, and San Ignacio Mines in Guanajuato). Bear Creek provided an update on the USD $25M payment to Equinox Gold for the Mercedes mine in Sonora. ON SOCIAL RESPONSIBILITY, Endeavour published its inaugural climate strategic report (Guanacevi mine, Durango).

ON MEXICO ISSUE

  • Servicios Industriales Peñoles S.A.B. de C.V., and Fresnillo plc recognized the role of women in mining, commemorating his legacy from the beginning of his participation in this sector. Both companies have maintained a strong gender agenda that offers equal opportunities to women and men, equal salaries that depend on the responsibilities of each employee, programs to prevent harassment and to reinforce female leadership.
  • In Mexico, women in mining have access to salaries up to 30% higher than the national average, with remunerations that exceed MXP $11K a month, above the MXP $5K and up to MXP $7K received by workers in the agricultural and construction sectors, textile employees, drivers and merchants, according to sector estimates. The mining industry has made progress on issues of diversity and inclusion, since in the last 13 years the participation of women has increased, going from 33,260 at the end of 2008 to 66,037 by 2022, according to data from Mining Chamber of Mexico (CAMIMEX).
  • According to figures from the Mexican Social Security Institute (IMSS), more than 66,000 women work in the mining-metallurgical industry, which is equivalent to 16.3% of the total workforce. The number of women who are entering careers in mining engineering, metallurgy and geology is increasing and therefore their presence in the productive field and in the management of the operation of mining units is increasing. Of the total number of women who participate in the industry, 10% hold directive positions and 14% hold management positions.
  • Proposals to modify the Mining Law lack support, say experts, since the industry complies with at least 4,000 legal obligations, before starting operations of a mining unit. The reform initiatives to the Mining Law that have been presented in the Congress of the Union lack support in the real circumstances of this industry or refer to issues that should be the subject of other legal regulations, as uncertainty for this activity. The experts explained that issues such as creating or increasing taxes and/or rights must be ruled out in the legislative drafts, since mining entrepreneurs pay, like any other taxpayer, the Income Tax, the Special Tax on Production and Services, in addition to they also pay mining rights and some local contributions, such as payroll and property taxes, as well as some of the so-called ecological taxes. They added that it is estimated that the tax burden of mining in Mexico is high, compared to other countries with mining activity. Mining is an industry misunderstood and unknown by many, even by those who promote changes to its legislation, for which they trusted that the voice of those who know and participate directly in the industry will be heard.
  • GoGold Resources Inc., and Torex Gold Resources Inc., reported the best drilling intercepts in Mexico on the second week of March, 2023. Details are shown in the table below:

ON EXPLORATION

  • Aztec Minerals Corp., reported that it has commenced the 2023 exploration program at its Cervantes project in Sonora.

It will comprise collecting over 1,300 geochemical samples, including 950 roads cut, 120 soils, and 250 outcrop chips.
  • Prismo Metals Inc., announced that it has received authorization for drilling its Palos Verdes project, located in the historic Panuco-Copala mining district in Sinaloa. The company plan is to complete a 2,500m drilling program to test the strike length of the Palos Verdes Vein that was not previously accessible until now.
  • Vortex Metals Inc., provided an update on the environmental works it has conducted at its flagship Riqueza Marina project in Oaxaca.
