Quartz-Sericite-Pyrite (Phyllic Alteration).

By Miguel A Heredia

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.

Mexico’s Best Drilling Intercepts, Second Week of March 2023

/ Gambusino Prospector / Leave a comment

Torex Gold and GoGold Resources reported drilling results on their Mexican projects during this week. Torex Gold continues to advance the Media Luna project in Guerrero into operation, and released very good gold silver and copper intercepts, The company’s drilling is designed to upgrade and expand the resource. “The Media Luna deposit is hosted within the Mesozoic carbonate-rich Morelos Platform, which has been intruded by Paleocene stocks, sills, and dykes of granodioritic to tonalitic composition. Skarn-hosted gold-silver-copper mineralization is developed within the sedimentary rocks along the contacts of intrusive rocks as well as within altered dykes of the skarn envelope”.

Drilling at the Main and Eagle areas on Los Ricos South property in Jalisco returned good gold and silver grades over widths over ten meters. GoGold is trying to select areas to mine with a lower strip ration and area to mine by selective bulk underground mining on this structurally controlled epithermal low sulfidation deposit.

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

/ Gambusino Prospector / Leave a comment

Five companies reported results of drilling on Mexican projects during the first week of March 2023. The five properties present epithermal mineralization of low to intermediate sulfidation character deposited along structures and/or related stockworks and dissemination on favorable rocks.

Vizsla’s Silver Panuco project in Sinaloa presented the higher grade gold intercept, with 15.0 m averaging 7.20 gpt Au (108 gpt*m). The released intercepts are part of the resource area of the Copala structure at its Panuco project in Sinaloa. Other relevant gold results are those coming from Gold Resource’s Don Diego mine in Oaxaca, with 4.21 m at 7.93 gpt Au and Prime Mining’s Los Reyes property in Sinaloa with 15.80 m averaging 1.40 gpt Au.

On silver, the strongest intercept was that by Vizsla’s at its Panuco project with 15.0 m grading 1,142 gpt Ag (or 17,130 gpt *m), followed by Silver Tiger’s intercept of 57.20 m averaging 232 gpt Ag (or 13,270 gpt*m) from its El Tigre project.

Base metals intercepts were led by results from Silver Tiger’s El Tigre , with 57.20 grading 0.41% Cu and 20.0 m at 4.11% Pb, 8.15% Zn on the Sulfide zone still being defined.

ON MEXICO ISSUES, Almaden regretted the decision of Mexico´s Ministry of Economy to deny the two mineral title applications which were first made by Almaden in 2002 and 2008, and which in turn led to the grant of mineral titles in 2003 and 2009, respectively. GoGold, Bear Creek, GR Silver, and Guanajuato Silver reported the best drilling intercepts in Mexico on the fourth week of February, 2023. ON EXPLORATION, In Sonora, Tocvan released results from surface channel sampling of selected area for a bulk sample at its Pilar project.  In Coahuila, Monumental Minerals provided an update and defined drill targets at its Jemi Heavy Earth Rare Element project. ON MINING, Coeur reported Q4 and full year 2022 production and financial results from its Palmarejo mine in Chihuahua. Starcore announced Q3, 2023 production results from its San Martin mine in Queretaro. Equinox provided 2023 guidance for its Los Filos mine in Guerrero. Bear Creek announced 2023 production guidance for its Mercedes mine in Mexico. Gatos Silver released 2023 production and cost guidance for its Cerro Los Gatos mine in Chihuahua. First Majestic reported Q4 and full year 2022 production and financial results from their Mexican mine operations. ON FINANCING, Silver Tiger closed its previously announced bought deal offering for gross proceeds of approximately CAD $18M (El Tigre project, Sonora). ON RESOURCES AND DEVELOPMENT, GoGold reported additional drilling results from Los Ricos South, within the Eagle and Main Deposits in Jalisco. Guanajuato Silver announced drill results from its San Ignacio mine in Guanajuato. Alamos Gold reported Mineral Reserves and Resources for the year-ended 2022 at its Mulatos project, Sonora. Bear Creek released results of recent drilling from its Marianas and Rey de Oro deposits at its Mercedes mine in Sonora.

ON MEXICO ISSUE

  • Almaden Minerals Ltd., regretted the decision of Mexico´s Ministry of Economy to deny the two mineral title applications which were first made by Almaden in 2002 and 2008, and which in turn led to the grant of mineral titles in 2003 and 2009, respectively. These mineral titles underpin the Ixtaca deposit which was discovered by Almaden in 2010. As previously reported, these mineral titles were reduced to application status as a result of an early 2022 decision of Mexico’s Supreme Court of Justice (SCJN). Almaden believes that this action by the Secretariat of Economy is inconsistent with the Mexican Mining Law, the SCJN decision, and international law. The Company expects to submit arguments challenging the Secretariat of Economy’s submissions to the District Court within the next few days.

GoGold’s Los Ricos South is a property with prior small scale mining on structures in a low to intermediate sulfidation epithermal system in Jalisco. The company has been demonstrating with drilling for the past couple of years that mineralization is well beyond the border of the previously worked high grade structures, with mineable grades over tens of meters.

GR Silver has a large property in Sinaloa encompassing several mineralized systems. The current results are from the past producing Plomosas mine area, which is part of a strongly mineralized centre of epithermal intermediate sulfidation mineralization mined not so long ago by IMMSA.

Bear Creek’s Mercedes property in Sonora is mining veins part of a low sulfidation epithermal system with good gold grades.

The results from the San Ignacio vein system by Guanajuato Silver are from low sulfidation epithermal mineralization to be mined for processing on the the Cata Mill at the Valenciana mines complex. San Ignacio forms part of the properties package the company obtained from Great Panther not long ago.

ON SOCIAL RESPONSIBILITY, no relevant news.

ON MEXICO ISSUES

  • The Mexican president, Andrés M. López Obrador announced on one of its daily propaganda conferences: “I am to sign the decree to forward the lithium concession, all the reserves, to the Energy Secretariat”. In April 2022 the government declared lithium as a public utility mineral, and its exploitation to be only possible under the public enterprise Litio para México.
  • Margarita Vélez Rocha, the Sonora Economy Secretary, recognized the importance of the mining sector in the State, pointing that it directly employs more than 26 thousand workers and more than 120 thousand indirectly, with 39 municipalities having mining activities and 23 on which it is the main economic activity.

ON EXPLORATION

  • Southern Empire Resources Corp. announced that synchrotron radiation micro-X-ray fluorescence mineralogical studies of drill core samples from its Pedro project in Durango reveal mineralogical similarities to deposits of the Carlin belt in Nevada. Gold mineralization at Centauro and Pedro projects, both in Durango, is associated to hematite-stained, weak to moderately silicified brecciated conglomerate of the Eocene to Oligocene Ahuichila Formation. Historic drilling results include intervals like 5.60 m @ 0.59 gpt Au; 19.82 m @ 0.31 gpt Au; 15.23 m @ 0.58 gpt Au; 50 m @ 0.28 gpt Au; 88.10 m @ 0.24 gpt Au; 112.40 m @ 0.12 gpt Au, with anomalous Ag, As, Sb Tl and Hg.

ON MINING

  • Gold Resource Corp. issued 2023 guidance and suspension of dividends. For 2023 the company expects to produce 17 to 19 K Oz Au, 0.9 to 1.0 M Oz Ag (or 30 to 32 K Oz AuEq) at cash cost $1,000 to $1,050 per AuEq Oz and an AISC of $1,250 to $1,350 per AuEq Oz (Consolidated: $1,650 to $1,750 per AuEq Oz). “the lower grade profile is expected to continue through 2023 and is projected to negatively impact operating cash flows and total cash costs per gold equivalent ounce”, and accordingly “will suspend the quarterly dividend until such time that it may become practicable to reinstate” (Don David, Oaxaca).
  • Capstone Copper Corp. reported financial results for Q4 2022 and year 2022, including figures from its Mexican operations. At Cozamin, in Zacatecas, 3,430 tpd were milled during the quarter to produce 5.8 K tonnes of copper, totaling 24.5 K tonnes Cu on the year at cash cost $1.40 per Lb Cu (which is the lowest cost for Capstone operations). Cash and cash equivalents stood at $170.3 M by the end of the period.

ON FINANCING

  • Reyna Silver Corp. announced the closing of the first tranche of its bought deal private placement for gross proceeds of C$5 M (Guigui and Batopilas, Chihuahua).
  • Mag Silver Corp. completed the previously announced bought deal private placement for aggregate gross proceeds of C$23 M (Juanicipio (44%), Zacatecas).
  • Orogen Royalties Inc. authorized the granting of 156 K restricted share units, 156 K deferred share units and 238 K stock options to independent board members (Royalties on Ermitaño, Sonora).
