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 Third Week of April, 2023.
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 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.

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

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

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 EXPLORATION

The Mining and Exploration News in Mexico: Highlights on the Fourth Week of September, 2022.
By Miguel A Heredia
During the 38th week of the year (September 19th to September 25th, 2022), at least 12 press releases were announced by companies working in Mexico, and 3 news published by the media with four informing on exploration results, four reporting resources and developments of their properties, four commenting on Mexican issues, two announcing financing issues, and one discussing social issues. ON MEXICO ISSUES, Enrique Zorrilla, president of the Canadian Chamber of Commerce in Mexico stated that Canada has its eyes fixed on Mexico as an investment destination for its mining companies, mainly in exploration expenses to find new gold deposits. According to a recent report by the Ministry of Finance, Mexico values its lithium deposits in Sonora at USD $602,000M. In Mexico, only 33% of mines have access to a computer with an Internet connection to reduce accidents. On a striking difference with last week news releases, only Vizsla Silver Corp., posted drilling results in Mexico on the fourth week of September, 2022. ON EXPLORATION, In Sonora, Tocvan and its JV partner Colibri announced the next steps to be conducted at both the Pilar and the El Picacho projects. In Sinaloa, Prismo provided an update of its ongoing drilling program being conducted at its Palos Verdes project. In Durango, Regency entered into an option agreement to acquire a 100% undivided interest in the El Tablon claims. ON MINING, no relevant news. ON FINANCING, Tocvan announced that it has filed to extend the expiration date of 1,244,668 common share purchase warrants by six months (The Pilar project, Sonora). Barksdale closed a non-brokered private placement for gross proceeds of $2M and issued a total of 4,622,917 units at a price of $0.48 per Unit for gross proceeds of $2.22 (San Javier project, Sonora). ON RESOURCES AND DEVELOPMENT, Oroco announced the commencement of a Preliminary Economic Assessment (PEA) for its Santo Tomas project in Sinaloa. Galore provided an update on the exploitation activities carried out at its Duraznillo mine in Zacatecas. Golden Tag reported positive metallurgical results from the Fernandez Zone at its San Diego project, Durango. Vizsla reported results from 13 new drill holes targeting the Cruz Negra Vein located in the western portion of its Panuco project in Sinaloa. ON DEALS AND CORPORATE ISSUES, no relevant news. ON SOCIAL RESPONSIBILITY, Almaden signed new and expanded cooperation agreements with the two communities closest to its Ixtaca project, Puebla.
ON MEXICO ISSUE
- Enrique Zorrilla, president of the Canadian Chamber of Commerce in Mexico stated that Canada has its eyes fixed on Mexico as an investment destination for its mining companies, mainly in exploration expenses to find new gold deposits. He declared that 35% of the capital invested by that country goes to the mining sector.
- According to a recent report by the Ministry of Finance, Mexico values its lithium deposits in Sonora at USD $602,000M. Although Mexico does not currently produce the metal, the finance ministry estimated that Sonora’s reserves could add about 0.3% to potential GDP in the medium term. While the ultra light white metal is usually extracted from rock or brine deposits, lithium in Sonora is mostly trapped in clays, from which it has not yet been extracted on a commercial scale.
- In Mexico, only 33% of mines have access to a computer with an Internet connection to reduce accidents. Ericsson revealed that the use of tools such as telemetry, satellite geolocation, wireless sensors and remote operation help improve mining operations, because with them and with the speed of the 5G network, information can be obtained practically in real time.
- On a striking difference with last week news releases, only Vizsla Silver Corp., posted drilling results in Mexico on the fourth week of September, 2022. Details are shown in the table below:
ON EXPLORATION
- Tocvan Ventures Corp., and its JV partner Colibri Resources Corporation announced the next step to be conducted at both the Pilar and the El Picacho projects in Sonora. At the El Picacho, Tocvan plans to initiate a maiden drill program targeting the San Ramon prospect. The plan for the Pilar is to commence bulk sampling of trench material to be processed in a local heap leach facility; to complete 2,000m of infill drilling and 3,000m of step-out and exploration drilling; to proceed with the permitting and development requirements for establishing a bulk test mine on-site; and to update the technical report.
- Prismo Metals Inc., provided an update of its ongoing drilling program being conducted at its Palos Verdes project, Sinaloa. The Company has drilled approximately 560m in two core holes of a planned minimum of 2,000m drill program, with the second hole currently in progress. Both holes have intersected several vein structures. Palos Verdes project is contiguous to the Panuco silver-gold project of Vizsla Silver Corp.
- Regency Silver Corp., entered into an option agreement to acquire a 100% undivided interest in the El Tablon claims located only 26km from the historical Tayoltita mining district in the state of Durango.

ON MEXICO ISSUES, Colibri and Oroco reported the best drilling intercepts in Mexico on the fourth week of August, 2022. 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). According to the Mining Chamber of Mexico (CAMIMEX), a total of 822 mining projects remain on hold and represent an amount of USD $959M. Jaime Gutierrez Núñez, president of CAMIMEX stated that small-scale coal mining is like “the blood diamonds” of Africa. Mexico’s mining industry plans to invest USD $5.5B in 2022, 15.2% more than in 2021. Mining in Mexico grew by 7.1% in 2021 despite friction with the government. 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. In Mexico there are more than 1,209 mining projects that have been developed in 26 states of the Republic. ON EXPLORATION, In Sonora, Colibri reported results from the second half of its Phase 1 drill program completed on its Evelyn project, and Tocvan announced latest drill results from its Pilar project.

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:

· 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 ISSUE
- Jaime Gutiérrez Núñez, President of the Mexican Mining Chamber (CAMIMEX) stated that political risk causes a reduction in the mining investment in Mexico. The lack of legal certainty and a complex environment for obtaining licenses and concessions are holding back investment in the Mexico’s mining sector, despite the rise in metal prices. Actual spending was USD $4.25B, 15.6% below the original estimates, according to CAMIMEX. The figure is lower than the USD $4.67B in 2019 and is well below the high of USD $8.42B in 2012. Due to the lack of mining concessions, investment opportunities of USD $25B are lost in the country. Currently, there are 29 applications detained in the Secretary of the Environment and Natural Resources (SEMARNAT) and 34 at the National Water Commission (CONAGUA). With an adequate legal framework and adequate incentives, mining activity could generate 50 thousand additional direct jobs and more than MXP $25B a year in addition to those already paid by mining. “The statements of the President (against mining), not granting mining concessions, denying access to information, making procedures increasingly slow, although the terms are established in the law, and the lack of personnel in the Mining Directorate General have impeded the advancement of mining projects in the country”.
- Alfonso Durazo, governor of Sonora State, declared that the Mining Fund program could be back in the state after it was frozen for a little more than three years by the Federal government. If the Mining Fund is back, the injection of resources into the entity in this 2022 will be greater than MXP $1,000M, same that will benefit the mining towns and incidentally will give a good respite to state public finances.
ON EXPLORATION
- Reyna Gold Corp., reported surface and trench sampling results from its La Gloria project. To date, 1,252 sample results have been received from the Main Zone area where drilling will commence this coming February. A total of 555 samples out of 713 returned greater than 0.1 g/t Au, including 23 with greater than 5 g/t Au at Big Pit area. High grade values were encountered at Big Pit and Pique Viejo areas including values of 93.9 g/t Au, 36.2 g/t Au, 46.1 g/t Au, 24.4 g/t Au, 20.1 g/t Au. Other areas such as Las Quintas, Las Quintas West, San Pedro, and Alamo Muerto returned values of 20.1 g/t Au, 15.9 g/t Au, 13.3 g/t Au, 11.1 g/t Au, 13.6 g/t Au, and 9.3 g/t Au. Reyna Gold has already the drill permits to commence a drilling program at Big Pit and Pique Viejo areas in February, 2022. Sampling and mapping will continue in other target areas of the property.
