Quartz-pyrite-FeOx stockwork veining

By Miguel A Heredia

During the 16th week of the year (April 18th to April 24th, 2022), at least 13 press releases were announced by companies working in Mexico, and three news published by the media, with four reporting resources and developments of their properties, three communicating production and financial results, three disclosing deals and corporate issues, three commenting on Mexican issues, two announcing financial issues, and one informing on exploration results. ON MEXICO ISSUES, Mexico Chamber of Deputies approved the initiative proposed by Andres Manuel López Obrador to reform the mining law on the nationalization of lithium. Fernando Alanís, Pro Secretary of the Confederation of the Industrial Chamber (CONCAMIN), declared that the project to reform the Mining Law to reserve the new concessions for the exploitation of lithium to the State is ambiguous and will add even more uncertainty and concern to investors. Armando Ortega, president of the Mining Task Force, of the Canadian Chamber of Commerce (CanCham) in Mexico, stated that the proposed reform of the Mining Law on lithium would violate Mexico’s commitments in international treaties.  ON EXPLORATION, In Sonora, Reyna Gold announced results from eight holes drilled at its flagship La Gloria project. ON MINING, Americas Gold and Silver reported Q1, 2022 production results from its Cosala mine in Sinaloa. First Majestic announced Q1, 2022 production results from their Mexican mine operations. Sierra Metals reported Q1, 2022 production results from their Bolivar and Cusi mines located in Chihuahua. ON FINANCING, Magna Gold announced completion of its debt settlement with PEAL de Mexico SA de CV (San Francisco mine, Sonora). Tarachi Gold amended the option agreement terms with Minerals de Tarachi (Magistral Mill and tailings project, Durango).  ON RESOURCES AND DEVELOPMENT, Magna Gold announced Maiden Resource Estimate for its Margarita project in Chihuahua. Bear Creek filed a NI 43-101 technical report for its Mercedes mine in Sonora, which includes the Mineral Reserves and Resources as of December 31, 2021. Oroco released results from its ongoing drilling program at its Santo Tomas project in Sinaloa.

ON MEXICO ISSUE

  • Mexico Chamber of Deputies approved the initiative proposed by Andres Manuel López Obrador to reform the mining law on the nationalization of lithium, with 275 votes in favor, 24 against and 187 abstentions. The reform contemplates the authorization of mining concessions with the exception of lithium, which will be administered directly by the Mexican State. López Obrador reiterated that his government will not allow foreigners to exploit lithium even if they have previous concessions. Instead, there will be a State company “to exploit, explore, extract, process, industrialize and sell it”.
  • Fernando Alanís, Pro Secretary of the Confederation of the Industrial Chamber (CONCAMIN), declared that the project to reform the Mining Law to reserve the new concessions for the exploitation of lithium to the State is ambiguous and will add even more uncertainty and concern to investors. Despite the fact that Mexico is among the 10 largest producers worldwide of 17 minerals, being the first in silver and the eighth in gold, the mining industry has lost attractiveness for investment in recent years after the government suspension of mineral concessions, in addition to the high taxes paid by the sector in our country.
  • Armando Ortega, president of the Mining Task Force, of the Canadian Chamber of Commerce (CanCham) in Mexico, stated that the proposed reform of the Mining Law on lithium would violate Mexico’s commitments in international treaties. He argued that minerals cannot be reserved, in this case, for the exclusive exploration and exploitation by the State, without having made the aforementioned reservation in the Treaty between Mexico, the United States and Canada (T-MEC). From his point of view, reservations are areas of exclusion of obligations and commitments, and to do so without prior negotiation is arbitrary and prohibited. The CanCham argued that reserving lithium only for the exploration and exploitation of the Mexican State ex-post is in violation of both the provisions of the World Trade Organization (WTO), as well as those corresponding to all Free Trade Agreements (FTA). ) signed by Mexico.

ON EXPLORATION

  • Reyna Gold Corp., announced results from eight holes totalling 710m of its ongoing 10,000m drilling program conducted at its flagship La Gloria project, Sonora.

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.

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

Hydrothermal breccia

By Miguel A Heredia

Happy New Year to all of our readers! I want to wish you all the very best in this coming 2022, especially good health, prosperity and a lot of fun!

With deep regret I knew early this week about the sensitive and unexpectedly passing of David Jones at his home in Tucson, Arizona. David was a well-respected geologist who worked for many years in Mexico making many friends. David will be remembered for being responsible of multiple discoveries in Mexico such as Los Filos in the Guerrero Gold Belt, and Switchback vein system at the El Aguila project in Oaxaca among others. “Descansa en paz amigo!”

During the 52nd and last week of the year (December 27th, 2021 to January 2nd, 2022), at least 13 press releases were announced by companies working in Mexico, and 2 news published by the media, with four reporting resources and developments of their properties, three disclosing deals and corporate issues, three informing on exploration results, three announcing financial issues, one commenting on Mexican issues, and one discussing social issues.  ON MEXICO ISSUES, Mexico will lose potential investments if it does not increase its level of certainty in the mining industry, warned Jody Kuzenko, CEO of the Canadian company Torex Gold Resources. ON EXPLORATION, In Sonora, Silver Spruce announced that it is proceeding with the preparation of an Informe Preventivo for trenching and drilling its Jackie property. In Durango, Southern Empire received preliminary results from a geophysical survey conducted at its Pedro Gold project. In Guerrero, Pantera Silver commenced a drilling program at its Nuevo Taxco Silver project.  ON MINING, no relevant news.  ON FINANCING, Altaley executed a loan agreement with Sail Natural for USD $5M (Tahuehueto project, Durango). Prismo completed the first closing of a non-brokered private placement for total gross proceeds of $1M (Palos Verdes project, Sinaloa). SilverCrest completed the third drawdown of USD $30M on its previously announced USD $120M Project Financing Facility (Las Chispas, Sonora). ON RESOURCES AND DEVELOPMENT, Fabled released results from its ongoing drilling program at its Santa Maria project, Chihuahua. Fresnillo and its JV partner Mag Silver provided a commissioning update on its Juanicipio project in Fresnillo, Zacatecas. GoGold provided an outlook and deliverables for 2022 (Los Ricos North and South projects, Jalisco). Silver Tiger provided a review of its 2021 activities at its El Tigre project in Sonora.  ON DEALS AND CORPORATE ISSUES, Gold79 retained Dig Media to provide investor relation services for the company (Taviche project, Oaxaca). Great Panther announced board changes (Topia mine, Durango). Minaurum announced the passing of David Jones. ON SOCIAL RESPONSIBILITY, Compañía Minera Cuzcatlán (Fortuna Silver) reported that its operation does not generate a negative impact on the water resource located in communities surrounding its San Jose mine in Oaxaca.

ON MEXICO ISSUE

  • Mexico will lose potential investments if it does not increase its level of certainty in the mining industry, warned Jody Kuzenko, CEO of the Canadian company Torex Gold Resources. Mexico’s mining industry has slowed because the current administration of President Andrés Manuel López Obrador has suspended the issuance of new mining concessions; likewise, companies in the sector are increasingly forced to deal with crime by hiring private security companies. Recently, the federal government proposed a constitutional reform initiative for the Mexican electricity industry in which it seeks for the Federal Electricity Commission (CFE) to regain a leading role in the sector, establishing that the company will generate at least 54% of consumption national electric. Torex Gold is the third largest gold producing company in Mexico, with 430,480 Oz Au in 2020; its operations are carried out in Guerrero, where Limón-Guajes is the second most important mining unit in the country in terms of gold production. In that same entity, the company plans to invest more than USD $500M to start operations at its Media Luna mining unit in 2024, with a production of 179K Oz Au, 21K tonnes of Cu and 1.5M Oz Ag, although these estimates will be updated with a new feasibility study. Since Torex Gold is growing in Guerrero, it will need more electrical power. “Reliability is required, that the power is not interrupted while you are working; the price must be competitive, and investors are looking for a wide margin in our process of decarbonization and reducing greenhouse gases”.

ON EXPLORATION

  • Silver Spruce Resources Inc., announced that it is proceeding with the preparation of an Informe Preventivo to be filed at the Mexican Government Environmental Authority (SEMARNAT) for conducting trenching and drilling at its Jackie property in Sonora. The environmental permit will include 13 trenches and 36 drill pads. The SEMARNAT permit for the Informe Preventivo is expected within four to six weeks of submission.”
  • Southern Empire Resources Corp., received preliminary high-resolution, airborne magnetic and radiometric geophysical data covering its Pedro Gold Project in Durango. In December 2021, Terraquest Ltd. of Markham, Ontario, collected 393.2 line-kilometers of airborne geophysical data on flight lines that were flown at azimuth 060 / 240 with 50m spacings. This data has been delivered to Condor Consulting, Inc. of Lakewood, Colorado; experts in geophysical processing, analysis and inversion modeling. “The results of our preliminary airborne magnetic data provide some strong clues about the structural setting and underlying ‘plumbing system’ of the HP Breccia gold zone. Together with the regional government magnetics, we see evidence for a deeper intrusive body that could be linked to the hydrothermal fluids and related potential for epithermal vein systems that are the target of Southern Empire’s upcoming drill campaign”. The company has mobilized a diamond drill rig to the Pedro Property and is scheduled to start a 2,000m, nine-hole core drill program in January of 2022.
  • Pantera Silver Corp., commenced a drilling program at its Nuevo Taxco Silver project in Guerrero. The first phase of this maiden exploration drill program will consists of up to 2,000m with holes of approximately 50-150m in depth.

ON MINING

  • No relevant news.

ON FINANCING

  • Altaley Mining Corporation executed a loan agreement with Sail Natural Resources LP for USD $5M. Net proceeds will be used to fund the final costs of construction and working capital at its Tahuehueto project in Durango. The loan agreement is for four years with an interest of 13.5% where Altaley shall make four quarterly payments of interest only on the outstanding amount of the loan commencing on March 10, 2022, and ending on December 10, 2022.
  • Prismo Metals Inc., completed the first closing of a non-brokered private placement for total gross proceeds of $1M (Palos Verdes project, Sinaloa). The company expects to complete a second closing for $1M in the first half of January, 2022. “The Company will use expected $2M gross proceeds from the Units to complete a 4,000m drilling campaign on its Palos Verdes property (estimated at $1M), conduct exploration on its Los Pavitos property, Sonora with a view of identifying drilling targets (estimated at $400K), the costs of the offering (estimated at $125K which includes payment of finder’s fees) and for general working capital”.
  • SilverCrest Metals Inc., completed the third drawdown of USD $30M on its previously announced USD $120M Project Financing Facility with an affiliate of RK Mine Finance. Funds will be used towards the continued construction of the Company’s Las Chispas Project located in Sonora, with a targeted completion in Q2, 2022. 

ON RESOURCES AND DEVELOPMENT

  • Fabled Silver Gold Corp., released results from its ongoing drilling program at its Santa Maria project, Chihuahua. The most significant drill intercept was obtained in hole SM20-45, which encountered a mined-out void zone at the target depth, but before reaching the target depth it intersected the Santa Maria footwall zone with 0.16 g/t Au 34 g/t Ag, 0.01% Pb, and 0.04% Zn (42.5 g/t AgEq) over 6.40m, including 0.23 g/t Au, 38 g/t Ag, 0.01% Pb, and 0.06% Zn (50 g/t AgEq) over 0.60m, and including 0.19 g/t Au, 55 g/t Ag, 0.01% Pb, and 0.04% Zn (68 g/t AgEq) over 1.7m.
  • Fresnillo plc and its JV partner Mag Silver Corp., provided a commissioning update on its Juanicipio project in Fresnillo, Zacatecas. Although the Juanicipio project team delivered the project for plan commissioning on schedule, the “Comisión Federal de Electricidad” (CFE), the state-owned electrical company, notified Fresnillo plc, the Juanicipio Project operator, that approval to complete the tie-in to the national power grid cannot yet be granted and the mill commissioning timeline will therefore be extended by approximately six months. Stoping and mineralized mine development at Juanicipio will continue and will make available any unused plant capacity at its Minera Fresnillo and Minera Saucito operations to process mineralized material produced at Juanicipio, and if possible matching commissioning and ramp up tonnages that were previously expected. The effect on cashflow generation from Juanicipio therefore will also be mitigated while CFE approvals are pending.
  • GoGold Resources Inc., provided an outlook and deliverables for 2022. At Los Ricos North, the company plans to conduct an aggressive drilling and exploration campaign on El Favor East and Gran Cabrera areas to increase the mineral resource estimate at the property. At Los Ricos South, GoGold will initiate a drilling program on the Jamaica structure since this mineralized zone offers the potential for an additional bulk tonnage target in Los Ricos South. The company also plans to initiate a PFS anticipated to be completed prior to the end of 2022.
  • Silver Tiger Metals Inc., provided a review of its 2021 activities at its El Tigre project in Sonora. The company reported wide high grade silver intercepts in quartz veins within a black shale horizon on the Sooy, Benjamin and Seitz Kelly Veins. Highlights include hole ET-20-202 in the Sooy Vein with 382 g/t AgEq over 22.2m, including 668 g/t AgEq over 11.75m; hole ET-21-204 in the Benjamin Vein with 519 g/t AgEq over 14.2m, including 1,010 g/t AgEq over 5.6m; and hole ET-21-264 in the Seitz Kelly Vein with 2,608 g/t AgEq over 17.5m, including 82,873 g/t AgEq over 0.5m. It also completed a $23M bought deal institutional financing, and disclosed 2021 Environmental, Social, & Governance (ESG) strategy roadmap.

ON DEALS AND CORPORATE ISSUES

  • Gold79 Mines Ltd., retained Dig Media Inc. dba Investing News Network, to provide investor relation services for the company. Under the terms of the contract for this advertising and investor awareness campaign, Dig Media will provide various digital media advertising and related services to increase public awareness of the company.

ON MEXICO ISSUE

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

ON EXPLORATION

  • Aztec Minerals Corp., and its JV partner Kootenay Silver Inc., commenced a 5,000m RC drilling program to test four main targets at the Cervantes project in Sonora. “The primary objectives of the drilling program are to better define the near surface, oxide gold potential of the porphyry gold oxide cap at California, evaluate the potential for deeper copper-gold porphyry sulfide mineralization underlying the oxide cap, test for north and west extensions of the California mineralization at California North and Jasper, and assess the breccia potential of Purisima East”.
  • Barksdale Resources Corp., announced the completion of the Phase I, 5,000m drilling program conducted at the Cerro Verde Zone within its San Javier project. All of the 36 holes collared at Cerro Verde encountering Cu mineralization. Significant drill results were encountered in hole SJ21-09 with 0.74% Cu over 18m, including 1.75% Cu over 15m; hole SJ21-07 with 1.47% Cu over 15m, plus 0.54% Cu over 12m; hole SJ21-15 with 0.49% Cu over 66m; hole SJ21-08 with 0.64% Cu over 18m, plus 0.54% Cu over 12m; and hole SJ-21-18 with 0.45% Cu over 12m. Although there are still 15 drill holes at the lab pending for results, the drilling has confirmed and expanded the footprint of the Cerro Verde Zone and indicates that Cu mineralization remains open particularly to the south, west, and northeast. The company has logged and sampled all the 36 drill holes collared during the 5,000m, Phase I drill program. It is currently working on completing an updated geological model in early Q1, 2022. Barksdale plans to conduct an initial resource estimate for the Cerro Verde Zone once assays are delivered by the lab. 
  • Canuc Resources Corporation provided an update on the ongoing exploration program at its San Javier project in Sonora. Approximately 11.2 km of drill and trench access roads were completed during the year. One of these roads encountered bedrock consisting of stockwork quartz veining and hydrothermal breccia. A strong northwest trending structure containing gold mineralization was identified along a strike length of more than 3 km. A total of 672 samples were collected from these trenches and road cuts, returning values ranging from <0.005 to 3.18 g/t Au; 00.3 to 169 g/t Ag, and 5ppm to 2.85% Cu. Highlights include 0.47 g/t Au and 0.37% Cu over 14.5m; 0.3 g/t Au over 56m; 0.21 g/t Au over 26m; 0.19 g/t Au over 10m; and 0.16 g/t Au and 0.48% Cu over 13m. Canuc also announced that 27 samples averaging 0.70m wide were collected from known magnetite bearing prospects in the northern part of the property returning up to 1.67 g/t Au, 1,877 g/t Ag and 6,823 ppm Cu, with a weighted average of 0.09 g/t Au, 295 g/t Ag, and 1,784 ppm Cu. In addition, seven channel samples averaging 0.8m wide collected from old mine workings found on recently acquired claims returned notable values in Au (up to 1.67 g/t), Ag (up to 511 g/t) and Cu (up to 1,854 ppm), with a weighted average of 0.15 g/t Au, 282 g/t Ag, and 604 ppm Cu. A drone-supported magnetic survey was completed late in the year and was accompanied by reconnaissance scale geological mapping. Several large magnetic anomalies were identified and targeted for drill testing. The San Javier area has become increasingly recognized as being highly prospective for IOCG, porphyry and other Intrusion-related Au, Ag and Cu-Au mineralization.
  • Tocvan Ventures Corp., commenced a 5,000-8,000m drilling program at its Pilar project. “Drilling will focus on continued step-out drilling along the Main Zone Trend and new 4-Trench Trend.
