Mexico’s Best Drilling Intercepts, First Week of June 2023

Two companies published drilling results from projects located in Mexico. GoGold’s had spectacular assays in gold and silver, with the best hole reporting 50 m grading 4.61 gpt Au, 780 gpt Ag, for 231 g*m Au, 39,010 g*m Ag. These intercepts are from holes in the Eagle zone, an area the company started testing on the second half of 2022. Vizsla’s Panuco project results are from the recently discovered La Luisa vein, located 700 m from the Napoleon resource area. The new results expand the high-grade footprint at La Luisa to 350 m long by 450 m along dip. Both properties structurally controlled low to intermediate sulfidation epithermal mineralization.  

Mexico’s Best Drilling Intercepts, Fourth Week of May 2023

Five companies released drilling assays from projects in Mexico during the week. The most impressive results are the gold intercepts by Heliostar Metals at the Ana Paula project in Guerrero. The company reported results from holes aiming to better define the high-grade core of the deposit, which will aid in the planning of an underground mine. The deposit sits at the northern end of the Guerrero Gold Belt, and is one of those beasts hard to put in a cage, as it presents several mineralization styles. The Morelos platform sediments are intruded by a plagioclase-biotite porphyry that produced local hornfelsification and skarnification of the sedimentary rocks. Pyrite, marcasite and arsenopyrite are present as veinlets, stockworks and disseminations in these altered rocks, in breccias, and as narrow semi-massive sulfide replacements at intrusive contacts. A late low sulfidation epithermal veining stage with visible gold is also present in the deposit.

Discovery Silver’s Cordero project in Chihuaha is also one of these deposits not easily cajoled to only a mineralization style, with high grade intermediate sulfidation epithermal veins cutting through (overprinting?) disseminated Ag-Pb-Zn mineralization (earlier?) related to the intrusion of felsic laccoliths, dikes and sills into a calcareous sedimentary sequence, with skarn and carbonate replacement mineralization dominating parts of the deposit. A very broad classification would put Cordero as polymetallic intrusive related mineralization.

Prime Mining’s Los Reyes project and GR Silver Mining’s Plomosas property, both in Sinaloa, are intermediate sulfidation epithermal systems with a strong structural component. Avino Silver & Gold’s is finding stronger copper grades 800 m below the surface on the Avino vein, and is considering the probable presence of a porphyry copper setting at depth.

The Mining and Exploration News in Mexico: Highlights on the First Week of May, 2023.

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.

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 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.

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.

ON RESOURCES AND DEVELOPMENT

  • Heliostar Metals Limited filed a technical report on an update of the 2017 pre feasibility study on the Ana Paula deposit in Guerrero, and announced re-scoping plans for its gold deposit. The Ana Paula deposit has a proven and probable mineral reserve of 14.1M tonnes with grades of 2.38 g/t Au and 6 g/t Ag for a total of 1.08M Oz Au and 2.5M Oz Ag contained. Ana Paula deposit is permitted for open-pit mining. The after-tax NPV (5% discount rate) of the Ana Paula Project is estimated assuming long-term metal prices of $1,600/Oz Au and $20/Oz Ag. The after-tax NPV (5%) of the Ana Paula Project is estimated at $278.6M with a projected after-tax IRR of 30.5%.  “The Ana Paula re-scoping program has four key areas of technical study: engineering, metallurgical, resource modelling, and geotechnical. These studies are designed to evaluate Ana Paula as a high-grade underground mine with a simplified and de-risked milling flow sheet”.
  • Avino Silver & Gold Mines Ltd., reported metallurgical results from the testwork program on its oxide tailings project at its Avino property in Durango. The tailings project hosts gold and silver from past producing historic operations with a 5.7 M tonnes of measured and indicated resource grading 95 g/t of silver equivalent.  The project consists of three types of tailings that are categorized by grade as well as identified in three stratigraphic layers within the deposit based on the time period when they were processed. They are, Ancient Oxides, Recent Oxides and Sulphides, and each type was sampled and tested separately. Metallurgical recoveries for the Ancient Oxides are 89.5% for Au and 90.4% for Ag; for the Recent Oxides are 85.8% for Au and 83.4% for Ag; and for the Sulphides are 82.8% for Au and 76.1% for Ag.
  • Silver Tigre Metals Inc., reported drill results from its El Tigre project in Sonora.
