ON MEXICO ISSUE

  • No relevant news.

ON EXPLORATION

  • Silver Spruce Resources Inc., filed environmental permits with the Secretariat of Natural Resources and Environment (SEMARNAT) to drill at their the Diamante, Mezquite and Jackie projects in Sonora. Approvals from SEMARNAT are expected to be obtained by late March, 2022.
  • Canasil Resources Inc., provided a review of the results from its 2020-21 drill program on the Candy Vein at its Nora project. 13 drill holes were completed for a total of 3,296m to test the Candy vein over a strike distance of 500m and to a vertical depth of 250m below surface. All the holes encountered the mineralized vein with the highest true width x grade value on hole NRE-21-11 with 5.31 g/t Au and 336 g/t Ag (748 g/t AgEq) over a true width (TW) of 11.29m, giving a TW x grade value of 8,445 g/t AgEq x m. The drill results show that the Candy vein hosts consistently high grade gold and silver mineralization over appreciable widths. The Candy vein is known over 3km long but only 500m have been drill tested. Additionally, Canasil reported that systematic grid soil sampling over a 2km east-west and 3km north-south area covering the central zone of the project returned widespread silver, gold, copper, zinc and lead geochemical anomalies. “The gold and silver anomalies are particularly strong over the 3-Km strike extent of the Candy vein structure on the western side of the project area, as well as to the southwest and east of the Candy vein structure. A strong silver and gold anomaly also extends for 1.5 Km southwest from the location of the above high grade drill intercepts on the Candy vein and a breccia target has been identified to the south with potential for hosting bulk tonnage disseminated silver-gold mineralization”.
  • Silver Wolf Exploration Ltd., provided a 2021 year in review and 2022 outlook on its Ana Maria property in Durango. The accomplished goals on 2021 include the completion of a NI-43-101 compliant technical report on the properties; an Aster satellite imaging survey, an airborne LiDAR and Hyperspectral imaging survey, an Airborne geophysical data survey, the application to expand the land package by 3x, and the completion of the 2021 mapping and sampling program to identify prospective areas and uncover previous historical workings.

The Mining and Exploration News in Mexico: Highlights on the Second Week of October, 2021

By Jorge Cirett

During the 41st week of the year (October 11th to October 17th, 2021), at least 25 press releases were announced by companies working in Mexico. To note, six companies posted exploration advances on their properties, six released Q3 reports and one on commencement of mining, two on financing and eight more on project development or resource definition and one more on mining concessions acquisitions. ON MEXICO ISSUES, Mexico’s president presented a proposal to change the law in the energy industry, but also restricting lithium exploration and production to the government. Several other elements could be included in the bill, referred to as “strategic minerals”, without elaborating, although a government party senator named cobalt, niquel, rare earths and even copper. ON EXPLORATION, In Sonora, Benjamin Hill Mining released results from geophysical processing and from fluid inclusion studies that support a buried intrusive source for the mineralization at the Benjamin Hill property; Canuc Resources updated on its deep drilling program at San Javier; Colibri Resources received the permit to drill Evelyn. In Chihuahua, Kootenay silver increased land holdings at its Columba project. In Sinaloa, Vizsla Silver presented drilling results from the Tajitos zone at its Panuco project.   ON MINING, Guanajuato Silver commenced mining at El Cubo, in Guanajuato. First Majestic Silver, Golden Minerals, Gold Resource, Magna Gold, Aura Minerals and Avino Silver & Gold Mines presented its Q3 2021 reports. ON FINANCING, Candelaria Mining informed one of its lenders, Accendo Banco, had its operating permit revoked by Mexican authorities. Xali Gold announced Sun River Gold arranged a financing for US$6.5 M for the tailings project at El Oro, Estado de Mexico. ON RESOURCES AND DEVELOPMENT, GR Silver Mining filed a NI-43-101 technical report on the Plomosas project, Sinaloa. Orla Mining provided an update on the construction of the Camino Rojo Oxide project. Prime Mining released further drilling results from Los Reyes, Sinaloa. Fabled Silver Gold released underground drilling results for Santa Maria, in Chihuahua. GoGold Resources reported results from drilling at El Favor, on its Los Ricos North project located in Jalisco. Golden Tag resources is adding 4,500 m to its 2021 drilling program at San Diego, Durango. Capitan Mining reported results from drilling at El Capitan, in Durango. Zacatecas Silver is drilling the Panuco and Las Cruces areas, at its Zacatecas project, results pending.   ON DEALS AND CORPORATE ISSUES, Argonaut Gold acquired from Fresnillo PLC 4,791 ha in key concessions surrounding its San Agustin mine in Durango. ON SOCIAL RESPONSIBILITY, Minera Media Luna, Peñols, Newmont Peñasquito and Pan American Silver informed on community programs in education and health.

ON MEXICO ISSUES

  • Mexico is far from being a powerhouse in lithium production according to the Statistical Review of World Energy 2021 by BP. Australia, Chile and China hold 81.2% of reserves and 86.5% of lithium production, whereas Argentina, Brazil, Portugal, the United States and Zimbabwe account for 20.5% of reserves and 12.8% of the production. Camimex (Cámara Minera de México) points that the constitutional reform presented by the Mexican president lacks technical support, as even if there are several lithium projects in Mexico, none has proven economic viability. The most visible of these projects, in Sonora, is said to be the largest lithium prospect in the Globe, but its economic viability has still to be proven, as to date there is not a single mine of lithium in clays in the World.
  • Mexico will not grant lithium concessions, said the Mexican president. He stated that even if his electricity reform is not approved by congress, his government has the power to reject any request for a concession to mine lithium. “We will deny any request for a concession to mine lithium and we have the power to do so. We want this to be established in the constitution, lithium belongs to the state”.
  • Nationalistic views with control on “strategic minerals” have been voiced by Morena, the party in power in Mexico. Besides the explicit aim by the President to save all lithium extracting and processing activities for the government, his recent proposal also refers, without elaborating, to be applied in other “strategic minerals”. A senator form Morena mentioned these other minerals could include cobalt, nickel, rare earths and copper, although a spokeswoman from the Economy Secretariat mentioned that the list of strategic minerals was to be provided by the Mexican Geological Survey at a later date.

ON EXPLORATION

  • Canuc Resources Corp. updated on the exploration program at its San Javier project in Sonora. Three holes have been completed and a fourth one is in progress, currently at 922 m of depth and ongoing. Chalcopyrite has been encountered from 302 m and is still visible at 922 m of depth. “The drill hole has intersected a broad zone of variably stockworked and brecciated Barranca sediments with minor andesitic dykes. The Barranca sediments show contact metamorphism from about 461 m and downward, variable amounts of magnetite bearing veinlets, stringers and breccia matrix throughout”. The first two holes intercepted Barranca Formation sedimentary rocks with magnetite veinlets and best intercepts of 2.35 m @ 126 gpt Ag and 2.0 m @ 243 gpt Ag. The third hole was drilled on the Tarahumara Formation volcanic rocks for 500.5 m before being terminated due to drilling problems, intercepting several volcanic lithologies, chalcocite from 38 m of depth and sulfides including chalcopyrite from 332 m. Scattered gold and copper values on short intervals were intercepted, of up to 1.19 gpt Au and 0.41% Cu. Results for the current hole are still pending.
  • Colibri Resource Corp. received the needed permit to drill up to 56 holes at the Evelyn project in Sonora. “The fully funded drill program of up to 10,000 metres is expected to be conducted in two phases”.
  • Kootenay Silver Inc. increased its land holdings at its Columba project in Chihuahua. The company applied for a 10,825 hectare concession, supporting the decision to do so on the high-grade silver intercepts on drilling of the property.
  • Vizsla Silver Corp. presented the results from 23 new drill holes from the Tajitos vein at its Panuco project in Sinaloa. Highlighted true width intercepts comprise 1.38 m @ 1.16 gpt Au, 79 gpt Ag; 1.34 m @ 7.94 gpt Au, 960 gpt Ag; 0.70 m @ 4.16 gpt Au, 2,082 gpt Ag; 2.15 m @ 1.09 gpt Au, 188 gpt Ag; 1.38 m @ 2.83 gpt Au, 527 gpt Ag; 8.7 m @ 0.51 gpt Au, 99 gpt Ag; 1.99 m @ 2.46 gpt Au, 615 gpt Ag; 0.86 m @ 3.37 gpt Au, 315 gpt Ag; 1.39 m @ 3.26 gpt Au, 73 gpt Ag; 1.3 m @ 2.47 gpt Au, 600 gpt Ag; 1.50 m @ 9.90 gpt Au, 2,607 gpt Ag; 0.7 m @ 5.73 gpt Au, 1,115 gpt Ag; 4.38 m @ 1.62 gpt Au, 216 gpt Ag.

  • Benjamin Hill Mining Corp. informed the seven kilometer long trend of epithermal mineralization at its Benjamin Hill project in Sonora is related to a well-defined magnetic anomaly. A magnetic high more than 12 kilometers long and 4 km wide lies beneath the surface, crossing the property in a N-NE orientation, with the Au-Cu mineralization parallel to the crest of the magnetic high.  “Our hypothesis explains that the magnetic anomaly corresponds to a partially exhumed fertile pluton. We suggest the mineralization seen at surface was driven by the heat engine of a buried pluton providing hydrothermal fluids that formed mineralized tabular bodies enriched with Au, Ag, and Cu (i.e. veins and breccias), as well as fluids that caused hydrothermal alteration halos (phyllic, epidote-magnetite and argillic alteration)…”.
  • Mammoth Resources Corp. updated on drilling at its Tenoriba project in Chihuahua. The company informed heavy rainfall during August and September is subduing by now, and that they expect an increase in the drilling rate that produced only 420 m of core in 8 weeks. “Mammoth intends to initially drill 2 – 4 holes within each target zone then move to another target zone to drill a similar number of holes”. Results on the first holes are pending.
  • Benjamin Hill Mining Corp. informed on results of fluid inclusion studies at its Benjamin Hill property in Sonora. The salinity and homogenization temperatures point to an epithermal system with an overprinting magmatic influence, and exhumation depths  between 150 m and 750 m in the mineralized structures. “This observation combined with recent geophysical data, supports the hypothesis of the existence of a mineralized plutonic source with a high possibility for Au-Cu metallic enrichment and porphyry potential”.

 ON MEXICO ISSUES

  • Mining Chamber of Mexico (CAMIMEX), demanded the authorities to act in the conflict between Peñasquito and a transport company called CAVA. The company declared that the illegal blockade which started more than a month ago, harms entire families and the productive chains of the region. CAMIMEX also stated that is essential that mining companies in the country can work without being subject to illegal pressures and, like any industry that develops in the country, their demands are met promptly through legal channels and attached to the rule of law. The company initiated the suspension of payments to employees and unionized workers, contractors, suppliers and communities. However, the company is willing to help unlock this situation that affects 20 thousand people who work directly or indirectly for the mine.
  • Mexico mining exploration, registered its lowest investment in 12 years. The mining exploration investment in Mexico during 2018 reached USD $383M, which represented a year-on-year decrease of 37.4% and its weakest level in the last 12 years, according to data from the Mining Chamber of Mexico (CAMIMEX).

ON EXPLORATION

  • Aloro Mining Corp., announced that soon it will resume drilling at its Los Venados project in Sonora. The drilling plan will consist of 1,200m in four holes and will be focused on the blind target discovered by hole LVRC-012 which intersected 32m of blind strong silicic alteration containing 1.72 g/t Au over 4.57m, interpreted as the margin of a concealed felsic dome.

He also is analyzing changes to the formula of distribution of the Mining Fund.

ON EXPLORATION

  • Aztec Minerals Corp., announced the completion of a helicopter-based airborne magnetic, radiometric , and VLF survey covering the entire 3,694 hectares with 100m spaced lines of its Cervantes project in Sonora. “Preliminary results show an extensive magnetic high under the California target extending and broadening towards the north. Other targets such as Purisima and Jacobo have either low to very high magnetic response respectively, suggesting that there is more than one phase of porphyry intrusions on the property. A large and interesting northwest-southeast oriented magnetic high was detected on the northwest side of the survey and corresponds to a newly identified area of extensive gossan oxide and pyrrhotite-pyrite- chalcopyrite-arsenopyrite mineralization in hornfels and sediments intruded by feldspar-quartz porphyry dykes. The pyrrhotite indicates a reduced copper-gold system and likely contributes to the magnetic high”. Aztec also reported high gold recoveries by cyanide leach analysis of 5 drill holes. Gold recoveries include 87% Au and 45% Ag over 98m in hole 18CER007, 84% Au and 54% Ag over 106m in hole 18CER006, and 84% Au and 49% Ag over 93.5m in hole 18CER003.
  • San Marco Resources Inc., completed a drilling program funded by Antofagasta plc, on its Chunibas project in Sonora. 1,640m of core in seven holes were drilled to confirm down-dip and along strike alteration and mineralization observed on surface along a 1.2km long NW-SE mineralized corridor and a 400m long NE-SW perpendicular mineralized corridor. San Marco reported that all holes intersected several intervals with visible fine grained disseminations and cavity fillings of bornite, chalcocite, and traces of chalcopyrite. Assays results are pending and will be released once the company makes its analysis and interpretation.
  • Mexus Gold US, released results of two holes drilled at the Julio area within its Santa Elena project in Sonora. Holes 4 and 5 averaged 0.8 g/t Au over 3 m and 2 m intercepts with a 1 m section of 1.4 g/t Au. Assay results are pending from holes 6 to 9 to complete the evaluation of the initial drill program on this target area.
  • Minaurum Gold Inc., announced the mobilization of a second drill rig to its Alamos Silver project in Sonora to accelerate the testing of new veins identified recently. Minaurum also announced rock sampling results and the discovery of the 1.2km long monzonite-hosted Salvia vein zone. Highlights of the rock sampling include 1m of 1,150 g/t Ag, 2m of 1.03% Cu, 1.2m of 3,240 g/t Ag, and 1.50m of 747 g/t Ag.
  • Colibri Resources Corporation, provided a review of its exploration activities during 2018 of its projects in Sonora. Colibri drilled 2,900m in 27 holes at its El Pilar project, extending the length of the known mineralized gold deposit 52% and confirmed many of the historical drill results from the previous operator. Drilling highlights of the 2018 program are 9m of 8.2 g/t Au, including 1.5m of 33.4 g/t Au; 28.5m of 0.57 g/t Au, including 3m of 4.24 g/t Au; 40.5m of 0.73 g/t Au, including 3m of 5.37 g/t Au; and 61.5m of 0.75 g/t Au, including 1.5m of 17.3 g/t Au. El Pilar and Evelyn projects have been reviewed by several companies for potential JV opportunities, however none agreement has been made at this time. The company also added two gold exploration projects named El Mesquite and Jackie by the purchase of Yaque Minerals, a private exploration company. El Mesquite contains a 600m long by 300m wide mineralized zone with values up to 3.41 g/t Au. Geophysical surveys have identified resistivity and chargeability anomalies with merits to be drill tested. Jackie is a grass root gold exploration project. An exploration campaign is expected to be carried out in 2019, which will consists of mapping, stream sediment sampling, chip sampling, and possibly a soil sample grid.
  • Prize Mining Corporation, released drill results from the Pilar Grande target within its Manto Negro project in Coahuila. Significant intersections are in hole DDHDI-18-05 with 2.5m of 0.72% Cu and 46 g/t Ag, including 0.55m of 1.43% Cu and 126 g/t Ag, and 0.45m of 1.74% Cu and 87 g/t Ag; hole DDHDI18-05 with 2.15m of 0.79% Cu and 37 g/t Ag, and 2.90m of 0.72% Cu and 24 g/t Ag.
  • Almadex Minerals Ltd., initiated a small “proof of concept” drill program at Gallo de Oro target within its Yago project in Nayarit where banded epithermal veins crop out at surface. At El Chato project in Puebla, Almadex has identified drill targets based on a defined IP chargeability anomaly beneath a zone of intense alteration interpreted to correspond with the upper portion of a buried porphyry system. Almadex geologists believe the El Chato has the same geological setting to that of Azucar Minerals Ltd´s El Cobre Cu-Au porphyry project in Veracruz.
  • Azucar Minerals Ltd., announced drill results from the North Zone within its El Cobre project on Veracruz. Highlights drill results at the North Zone include hole EC-18-053 with 231.50m of 0.45 g/t Au and 0.17% Cu, including 132m of 0.68 g/t Au and 0.24% Cu, and 70.20m of 1.07 g/t Au and 0.35% Cu, and 33.20m of 1.54 g/t Au and 0.49% Cu; hole EC-18-055 with 245.50m of 0.39 g/t Au and 0.17% Cu, including 148.50m of 0.54 g/t Au and 0.22% Cu, and 59.05m of 0.87 g/t Au and 0.32% Cu, and 33.30m of 1.10 g/t Au and 0.39% Cu; and hole EC-18-058 with 248.90m of 0.39 g/t Au and 0.19% Cu, including 74.50m of 0.67 g/t Au and 0.33% Cu, and 21.90m of 1.22 g/t Au and 0.55% Cu. Based on the drill results, the geologists have interpreted that “the mineralization appears to trend in NE-SW direction, that a late-mineral and barren to weakly mineralized intrusive occurs in the middle of the North Zone but tops out about 400m below the current surface, and that the mineralization remains open to depth, on either side of the late intrusion, and along strike to the northeast”.

ON MINING

  • Endeavour Silver Corp., provided an early review of its El Cubo mine plan in Guanajuato for 2019. The company plans to reduce the production rate in 2019 to approximately half its 1,500 tonnes per day, while continuing exploring for new reserves to extend the mine life.

ON MEXICO ISSUES

  • On the Torex Gold El Limon – Guajes mine illegal blockade in Guerrero (Editor’s comment). The illegal blockade promoted by the Los Mineros Union since November 3, 2017 is showing how far the government is willing to go, or not, to establish the rule of law. The Los Mineros Union is clearly trying to extortionate Torex with an illegal blockade to obtain the Union contract at the site, and delaying the date for a formal voting process that the company has vowed to respect.

ON EXPLORATION

  • Radius Gold Inc. released rock sampling results from its Amalia project in Chihuahua. A new discovery in the San Pedro area returned 13 m @ 2.51 g/t Au, 164 g/t Ag in a continuous chip sample (10 individual samples), while new sampling 50 m above and along strike the Guadalupe zone returned 8 m @ 0.21 g/t Au, 264 g/t Ag. At the Campamento zone a 500×700 m zone of intense silicification and brecciation with massive and stockwork veining is interpreted as high level mineralization. On lower parts of the property sulfide rich fault breccias are hosted in andesites, where mineralization is narrower and higher grade. Epithermal Au-Ag mineralization occurs along 3.5 Km on strike and 600 m of vertical interval. Drill permitting documentation has been submitted.
  • Gainey Capital Corp. signed a LOI to acquire the 9,200 hectares La Minita Cu-Au-Ag property in Sinaloa. A series of NW trending shears host porphyry mineralization associated with intermediate and felsic dikes, which are more than 300 m in length and up to 10 m in width. Fine grained sericitic alteration, silicification, quartz stockworks and copper sulfides (bornite, chalcopyrite) as disseminations and veins occur in prospect pits by gambusinos.

ON MINING

  • Great Panther Silver Ltd. announced that SEMARNAT granted all permits for construction and operation of the new phase II tailings storage facility at its Topia mine in Durango.
  • Mexus Gold US informed that it has produced gold with the installed Merrill Crowe system at its Santa Elena mine in Sonora (not to mistake with First Majestic’s Santa Elena mine, also in Sonora). The Merrill Crowe system will continue to be tested until the end of the year, as mine site security is upgraded before full production begins.
  • Americas Silver Corp. announced that the San Rafael mine at the company’s Cosalá operations in Sinaloa is now in commercial production, as of December 19, 2017. Mine production is currently averaging 1,200 tonnes per day (tpd) and increasing.

MGC-2017-11-23

THUNDER BAY, Ontario, Nov. 23, 2017 (GLOBE NEWSWIRE) — Mexican Gold Corp. (“Mexican Gold” or the “Company”) (TSX-V:MEX) (OTCMKTS:SRXLF) (FRA:4QW1) is pleased to announce that drilling to expand the high-grade dike contact mineralization outlined in hole LM-17-ED-40 has successfully intersected long intervals of chalcopyrite-magnetite mineralization in five additional recently completed holes. All of the holes intersected mineralization, with core intervals varying from 21 metres to 42 metres in length. The mineralization is located adjacent to and on both sides of the 70 metre wide dike with a known strike distance of 700 metres. The Eldorado/Juan Bran Zone has also been found to thicken substantially approaching the dike, which appears to be a vertical offshoot from the main El Dorado Sill.
