ON MEXICO ISSUE

  • President of the College of Mining Engineers, Metallurgists and Geologists of Mexico (CIMMGM), assured that, although there are promising geological signs in Chihuahua, Coahuila, Zacatecas, Oaxaca, Guerrero and Guanajuato, the Mining Law limits exploration of ‘rare earths’ in Mexico. The lack of formal exploration work imposed by the new legislation leaves Mexico at risk of becoming dependent on China, which controls 90 percent of global rare earth production. This is because the only one that can carry out exploration in Mexico is the Mexican Geological Service (SGM), which has reduced the interest of private parties to search for these minerals. For next year, the Secretariat of Finance and Public Credit (SHCP) granted the SGM a budget of MXP $1,320M, just MXP $127M more in relation to the MXP $1,193M that were granted for 2023, a budget that, they assure, will be insufficient. SGM explained that, if they do not have more budget, it will be difficult for them to meet the new mandates assigned to them by the Ministry of Economy, so, until now, they said, the most viable thing will be to work hand in hand with private sector.
  • Torex Gold Resources Inc., Endeavour Silver Corp., and Vizsla Silver Corp., reported their best drilling intercepts in Mexico on the third week of November, 2023. Details are shown in the table below:

The exploration potential of this structural corridor is open to the north and is likely favored by intersecting with the swarm of east-west dykes that define the best mineralization trap within both the nearby Media Luna and EPO deposits”.
  • Mammoth Resources Corp., announced results of an independent drill hole spacing analysis with recommendations to identify initial Mineral Resource Estimate (MRE) at its Tenoriba project, Chihuahua. The independent analysis recommended  drill hole spacing for the El Moreno, Masuparia, and Los Carneritos targets of 80m, 40m, and 80m respectively, for an Inferred MRE.
  • Oroco Resource Corp., filed an independently prepared Preliminary Economic Assessment (PEA) for its Santo Tomas project in Sinaloa. The report dated October 11, 2023 and titled “Santo Tomas Copper Project NI 43-101 Technical Report and Preliminary Economic Assessment”, has been prepared in accordance with National Instrument 43-101 – Standards of Disclosure of Mineral Projects.  Results of the PEA were previously announced in the Company’s news release dated October 17, 2023.  There are no differences in the Report from those results previously reported.

Diatreme breccia

By Miguel A Heredia

During the 40th week of the year (October 02nd to October 08th, 2023), at least 20 press releases were announced by companies working in Mexico, and 6 news published by the media, with nine commenting on Mexican issues, five disclosing deals and corporate issues, four reporting resources and developments of their properties, four informing on exploration results, two announcing financing issues, and two reporting production results. ON MEXICO ISSUES, Pan American suspended temporarily operations at its Colorada Mine in Zacatecas due to security concern. Grupo México declared that the Sonora River was successfully remedied, while the Ministry of the Environment and Natural Resources (SEMARNAT) presented a document stating that the presence of contaminating elements persists in the Sonora River basin after the Grupo Mexico spill in August 2014. President Andrés Manuel López Obrador said on Wednesday, October 4, 2023, that in about 15 days he hopes to have a proposal for action on the notorious case of a chemical spill from a mine owned by the giant Grupo México into a river in the north of the country in 2014. Mine Workers Union of Peñasquito Mine in Zacatecas, the Mexico´s largest gold mine, accepted operator Newmont Corp´s proposal to end a 4 month stop on Thursday night, October 5, 2023. Gold and silver mining companies listed in the United States and Canada stock markets suffered the decline in precious metals in the international market, due to the strength of the dollar, among other reasons. Chesapeake and Defiance Silver reported the best drilling intercepts in Mexico on the first week of October, 2023. ON EXPLORATION, In Coahuila, Monumental reported final results of its maiden drilling program at its Jemi heavy rare earth element project. In Sinaloa, Chesapeake reported a new gold discovery at its Lucy project. In Zacatecas, Radius provided an update of its drilling program at its Tropico project.

Radius completed the issuance of 500K common shares to Bruce Smith (Tropico project, Zacatecas).  ON SOCIAL RESPONSIBILITY, No relevant news.

ON MEXICO ISSUE

  • Pan American Silver Corp., suspended temporarily operations at its Colorada Mine in Zacatecas due to security concern. The company experienced an armed robbery of two trailers of concentrate. Fortunately, there were no physical injuries to the personnel. Pan American decided to suspend operations, project work, and exploration at La Colorada to protect the safety and security of the personnel.
  • Grupo México S.A.B. de C.V., declared that the Sonora River was successfully remedied, while the Ministry of the Environment and Natural Resources (SEMARNAT) presented a document stating that the presence of contaminating elements persists in the Sonora River basin after the Grupo Mexico spill in August 2014. In a statement, Grupo México pointed out that “The supposed findings of the sampling presented last week lack any causal link with the event that occurred in 2014. They fail to point out other current sources of contamination such as illegal mining, the discharge of untreated blackberries and the prolonged accumulation of residues of agricultural fertilizers and insecticides. The results released in recent days contradict those that CONAGUA and COFEPRIS have made public over time, which are supported by laboratories accredited by the Mexican Accreditation Entity (EMA) and endorsed by various institutions.” Grupo México argues that for five years after the accident, water monitoring was carried out in 35 sampling stations and 33 wells, in addition to bio-monitoring that included analyzes of exposure to metals, plant toxicity, genetics in invertebrates and flora. The document presented by the mining company states that “scientific evidence supports that the remediation of the Sonora River is recognized as successful and fully in accordance with the law,” and that the Sonora River region has been affected by continuous disinformation campaigns, arising with Political purposes.
  • President Andrés Manuel López Obrador said on Wednesday, October 4, 2023, that in about 15 days he hopes to have a proposal for action on the notorious case of a chemical spill from a mine owned by the giant Grupo México into a river in the north of the country in 2014. Last week, the environmental authority presented an opinion in which it concluded that the firm’s remediation efforts had not been sufficient and that the Sonora River continued to show the presence of contaminants nine years after the incident. On Wednesday, however, tycoon Germán Larrea’s company said the remediation was “successful.” At the time, the company was fined and had to create a trust to repair the damages. The president added that it seemed that the resources had not only been insufficient but also that their use had not been transparent.
  • Mine Workers Union of Peñasquito Mine in Zacatecas, the Mexico´s largest gold mine, accepted operator Newmont Corp´s proposal to end a 4 month stop on Thursday night, October 5, 2023. Mine Workers Union stated in a statement that as part of the agreement, workers at the Peñasquito mine will receive 8% more pay for each shift, and the increase will be retroactive to August 1, 2023. Each of the around 2,000 unionized workers will also receive an equal share of a total of MXN $152M (USD $8.3 M). The dispute over profit sharing related to 2022 will be decided by Mexico’s tax agency, while workers will receive 10% of profits for 2023 as long as the company makes a net profit in its income, according to the statement.
  • Gold and silver mining companies listed in the United States and Canada stock markets suffered the decline in precious metals in the international market, due to the strength of the dollar, among other reasons. The shares of the Mexican mining company Industrias Peñoles fell almost 5% this Monday, losing MXP $3,975M in capitalization on the Mexican Stock Exchange (BMV). In fact, the session hit a one-year low. Peñoles shares fell 4.87%, to MXP $195.45 each, making it the second station that lost the most in the session on the BMV. Its Fresnillo subsidiary listed on the London Stock Exchange lost 2.94%, to 5.35 pounds per share. Earlier in the day, Peñoles’ stock on the BMV reached a minimum of MXP $190.40, its lowest level since September 30, 2022. The American companies Newmont and Royal Gold fell 3.82 and 3.25%, in that order, on Wall Street, while the Canadian companies Wheaton Precious Metals and Pan American Silver fell 3.92 and 5.25%, respectively, on the Toronto Stock Exchange. In Mexico, the other three mining companies listed on the Stock Exchange (Grupo México, Compañía Minera Autlán and Frisco) did not present losses in their shares, because their income depends to a lesser extent on precious metals.
  • Chesapeake Gold Corp., and Defiance Silver Corp., reported the best drilling intercepts in Mexico on the first week of October, 2023. Details are shown in the table below:

ON EXPLORATION Monumental Minerals Corp., reported final results of its maiden drilling program at its Jemi heavy rare earth element (REE) project in Coahuila, which commenced on the Veladora North and South prospect areas. “Of the 2000 m drilled, 186 m of core (124 samples) returned anomalous REE concentrations. These samples contained total rare earth oxides (TREO1) results greater than 500 parts per million (ppm), with a maximum of 2018 ppm, and a mean and standard deviation of 717 and 282 ppm (respectively). Heavy rare earth oxides (HREO2) are also highest in these samples with a maximum of 517 ppm, and a mean and standard deviation of 164 ppm and 98 ppm (respectively). Anomalous TREO1 and HREO2 values were observed in every drill hole except JV-23-08 and JV-23-10”. Table below shows La Veladora significant assay results:

  • Chesapeake Gold Corp., reported a new gold discovery at its Lucy project, Sinaloa. The company completed 14 holes in the 2023 campaign for a total of approximately 1,710 m drilled. Drilling highlights include hole LU23-06 with 6.11 g/t Au over 24m; hole LU23-09 with 2.57 g/t Au over 30m, including 3.12 g/t Au over 24m; hole LU23-10 with 1.95 g/t Au over 21m, including 3.3 g/t Au over 9m; and hole LU23-13 with 3.95 g/t Au over 24m, including 5.44 g/t Au over 12m.
  • Radius Gold Inc., provided an update of its drilling program at its Tropico project, Zacatecas. As previously reported, hole TDD-001 planned for 300m to intercept Tropico target, encountered difficult ground conditions at 56m in a large brecciated fault zone. “This hole intercepted from 19m to 56m, intense altered clay, silicification, variable zones of hydrothermal breccia and sets of stockwork veinlets with banded silica veins.  Assay results from 18 samples returned 29m at 0.34 g/t gold from 24m downhole with the final sample returning 0.6 g/t Au. Diamond drill hole TDD-002 was collared 25m west of TDD-001 and drilled at -55° directly under TDD- 001 using larger diameter PQ core. The hole is still in progress. Below 25m of soil cover the hole intersected a 45m zone of epithermal alteration (similar to TDD-001) with clay, variable silicification, brecciation and zones of veinlets with occasional banded vein textures”. “Diamond drill hole TDD-003 was collared on the west of the Tropico breccia and drilled east at -65° to scissor holes 1 and 2 at depth. TDD-003 was collared in silicified crackle breccia and has to date intersected 80m of variably clay altered, silicified, and brecciated sediment. Significantly at 69m depth the hole intersected a 13m zone of white banded massive epithermal veining and breccia. The hole is still in progress”.
  • Vortex Metals Inc., reported that it is focused on the Rhyolite Dome area at its Riqueza Minera project in Oaxaca, and has moved westward toward the copper-bearing gossans of the Laminas zone, which may represent a Cu-rich stringer zone in the footwall of a VMS deposit. The company has excavated manually six trenches, totalling 188m, in which has identified broad exposures of iron- and manganese-rich exhalite horizons, silicified rhyolite flows and altered metasediments. Vortex has collected 117 samples and sampling results are anticipated to arrive in October.

ON MINING

  • Fortuna Silver Mines Inc., reported Q3, 2023 production results from its San Jose Mine in Oaxaca. The company milled 247,542 tonnes of 189 g/t Ag and 1.14 g/t Au with metallurgical recoveries of 91.31% and 90.71% respectively, to produce 8,205 Oz Au and 1.37M Oz Ag. The San Jose Mine plans to deliver annual silver production within the guidance range of between 5.3 to 5.8M Oz Ag.
  • Guanajuato Silver Company Ltd., provided an operations update of their four silver producing mines: El Cubo, Valenciana, and San Ignacio Mines in Guanajuato, and Topia Mine in Durango. “Since commercial restart at Valenciana Mine Complex in January 2023, steady production improvements, aided by the refurbishment of both the Cata shaft and a new underground locomotive system, have enabled the company to achieve production at the Cata Mill averaging over 20,000 tonnes per month from material sourced from Valenciana and San Ignacio”. “El Cubo operation is now milling at the rate of approximately 22,000 tonnes per month; this rate represents approximately half of the total capacity at the mill”. “The Company, in conjunction with the Secretaría Del Trabajo (the Federal Ministry of Labour), have been working to improve safety and security conditions at the mine in response to the unfortunate fatality that occurred in August 2023”. “The mineralized systems currently being mined at Topia are extraordinarily high grade yet are associated with higher extraction costs because of the narrow nature of the vein structures. With the goal of improving profitability at Topia, the Company intends to dramatically transform its operations through the exclusive use of local mine contactors”. The Company now anticipates that full year AgEq 2023 production will range from 3.4M to 3.6M Oz.

ON FINANCING

  • Excellon Resources Inc., completed the extension of the maturity date of its 5.75% secured convertible debentures from July 30, 2023 to July 31, 2024. In consideration for the extension, the company has issued 6,888,458 common shares of the company priced at CAD $0.156 per common share to the holders of the debentures in satisfaction of an extension fee in an amount equal to 6% of the aggregate principal amount of the debentures at the time of announcement (La Negra Mine, Queretaro).
  • Bear Creek Mining Corporation closed its previously announced bought deal financing. The company issued a total of 27.2M units at a price of CAD $0.35 per unit for gross proceeds of CAD $9.5M. Each unit is comprised of one common share of the company and one common share purchase warrant of the company. Each warrant will be exercisable to acquire one common share at an exercise price of CAD $0.42 per warrant share until October 5, 2028. Net proceeds will be used to support additional development work at its Mercedes Mine in Sonora, to expand on recent positive underground drill results, and for general working capital purposes, including CADS $3M intended to be used to reduce Mercedes ´trade payables to a normalized level over the next two quarters.

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

By Miguel A Heredia

During the 8th week of the year (February 20th to February 26th, 2023), at least 23 press releases were announced by companies working in Mexico, with ten reporting resources and developments of their properties, six communicating production and financial results, two informing on exploration results, two commenting on Mexican issues, one disclosing deals and corporate issues, one announcing financing issues, and one discussing social issues. 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 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 Resources Inc., Bear Creek Mining Corporation, GR Silver Mining Ltd, and Guanajuato Silver Company Ltd reported the best drilling intercepts in Mexico on the fourth week of February, 2023. Details are shown in the table below:

ON EXPLORATION

  • Tocvan Ventures Corp., released results from surface channel sampling of selected area from an up to 1,000 tonnes of oxide-gold bulk sample at its Pilar project in Sonora.
