By Jorge Cirett                                             

During the 25th week of the year (June 19th to June 25th, 2023), 16 companies working in Mexico posted news releases. Three companies informed on exploration work at its properties, while there was no relevant news on mining, other than the continuation of a Union strike on Peñasquito. Three companies informed on the closing of financing tranches or the arrangement of new placements. Four companies reported on work at their advanced properties. One company updated on financing moves to pay for the acquisition of an idle property and one more on the plans for recommence mining on their recent acquisition. ON MEXICO ISSUES, Newmont declared force majeure on contracted base metal production due to the Union strike at Peñasquito. The first all-encompassing suspension on the recently passed Mining Law was granted to a Mexican mining company. The Sindicato Nacional de Mineros brought a complaint before the fast-response mechanism of the T-MEC, accusing Grupo Mexico of negating Union liberty since 2007. Grupo Mexico responded the San Martín mine operates with the free decision of its unionized workers, and that workers strongly support the current Union.  ON EXPLORATION, in Sonora, Colibri Resource updated on work at El Plomo project. In Coahuila, Monumental Minerals announced a maiden drill program at its rare-earth Jemi project. In Durango, Silver Dollar entered into a surface access agreement with the local Ejido at Nora. ON MINING, no relevant news. ON FINANCING, Canuc Resources closed a CAD$1.3 M financing round. Sonoro Gold closed the first tranche of a C$3 M financing, raising C$1.7 M. Coeur Mining arranged a private placement for $19 M. ON RESOURCES AND DEVELOPMENT, Prime Mining reported good drilling results below the resource shell at Los Reyes, in Sinaloa. Orla Mining released infill drilling results from the Sulphide zone at Camino Rojo in Zacatecas, and also from the Deep Extension zone and from an exploration play 7 km away. Aztec Minerals updated on geologic and geochemical information at Cervantes, in Sonora, and is preparing an RC drilling campaign. Discovery Silver provided an update on work at the Cordero project in Chihuahua. ON DEALS AND CORPORATE ISSUES, Excellon Resources updated on La Negra acquisition in Queretaro, and the financing arrangements being sought to support it. Impact Silver announced its plans for refurbishing the Plomosa mine and plant in Chihuahua. ON SOCIAL RESPONSIBILITY, no relevant news.

ON MEXICO ISSUES

  • The first suspension with all-encompassing application against the recently approved Mining Law was granted by a federal judge from Mexico City on June 21, 2023, to Cobre del Mayo, the company that exploits the Piedras Verdes copper mine in Sonora. Before this ruling, the only suspensions admitted were for the automatic rejection of previously filed applications for mining concessions.
  • The Sindicato Nacional de Mineros (National Miners Union, headed by Napoleón Gómez Urrutia) presented a complaint against Grupo México under the fast response mechanism of the T-MEC, accusing the company of negating Union liberty and failure to comply with legal rulings on its favor, relating to a strike commenced by the Union in 2007 in which safety and contractual obligations were demanded. (It is much more likely that Napoleón Gómez Urrutia was aiming for the invalidation of a court arrest warrant on him related to the subtraction of 55 M dollars granted to workers of the Cananea mine on the sale of the property to Grupo Mexico. Napoleón Gómez Urrutia has legal immunity by its position as a senator). Grupo Mexico replied that its workers strongly back the current Union, and that the San Martín mine in Zacatecas operates with the free decision of its unionized workers.
  • Newmont declared “Force Majeure” on the production of lead and zinc that is to impact on contract obligations. The company was to produce about 200 K tonnes Zn and 80 K tonnes Pb on 2023, but the current Union strike is going to impact on its production forecast. Operations were suspended on June 7, 2023, by the Union, which is demanding an increase of the participation on the profit obtained by the company from 10% to 20%.

ON EXPLORATION

  • Colibri Resource Corp. reported results from geological mapping and outcrop sampling at the Pavo Real target on the Plomo property, EP project in Sonora. A 0.5 Km by 0.5 km area was selected and 90 grab samples collected, with 38 samples returning over 0.1 gpt Au and 13 samples over 1.0 gpt Au, peaking at 9.94 gpt Au. “The higher-grade samples also commonly include veinlets mapped as jasperoid which in thin section was determined to be a very fine-grained assemblage of limonite and hematite and interpreted to possibly be derived from a primary Fe-carbonate bearing vein assemblage. The mineralized tourmaline bearing breccia and stock work samples are massive to strongly foliated where foliation consistently has a north-northwest strike and moderate northeast dip”.
  • Monumental Minerals Corp. announced a maiden drill program planned for its Jemi rare earth element project in Coahuila. Exploration work has resulted in six high priority drill targets for dysprosium (Dy), terbium (Tb), neodymium (Nd), Praseodymium (Pr), niobium (Nb) and tantalum (Ta). “The goal of the drill program is to define and delineate the source of REE-mineralized (eudialyte +/- aegirine rich) intrusive dykes and sills”. The program envisages 1,800 m of drilling in 6 holes.
  • Silver Dollar Resources Inc. entered into a surface rights agreement with the Ejido Peña, covering the area of the Nora project in Durango.

ON MINING

  • No Relevant News.

ON FINANCING

  • Canuc Resources Corp. announced the closing of the first tranche of a non-brokered private placement financing, raising CAD$1.28 M in gross proceeds. (San Javier, Sonora).
  • Sonoro Gold Corp. closed the first tranche of the C$3 M previously announced non-brokered private placement, for gross proceeds of C$1.7 M. Directors and officers participated in the offering for $1.32 M, constituting a related party transaction at the TSX Venture Exchange (Cerro Caliche, Sonora).
  • Coeur Mining Inc. arranged a private placement for gross proceeds of $19 M (C$25 M). “The proceeds of the Offering will be used exclusively for qualifying Canadian Exploration Expenditures” (Palmarejo, Chihuahua).

ON RESOURCES AND DEVELOPMENT

  • Prime Mining Corp. reported drill results from four holes at the Z-T area of the Los Reyes project in Sinaloa. Two of the holes are located 100 to 200 m below the recently announced resource pit shell. Highlighted true width core intervals comprise 13.25 m @ 3.80 gpt Au, 82 gpt Ag (including 3.65 m @ 8.15 gpt Au, 89 gpt Ag); 11.40 m @ 3.96 gpt Au, 88 gpt Ag (including 2.00 m @ 19.40 gpt Au, 168 gpt Ag). “Together the mineralization in these drill holes further defines two high-grade mineralized shoots separated by 250 m. These intercepts open a significant area of exploration upside relative to the MRE pit shell for the Z-T area.”
  • Orla Mining Ltd. provided an update on exploration at its Camino Rojo project in Zacatecas. Highlighted core length results comprise 93.0 m @ 2.87 gpt Au; 56.9 m @ 3.26 gpt Au; 34.0 m @ 3.11 gpt Au (including 5.6 m @ 10.29 gpt Au); 43.0 m @ 2.12 gpt Au; 38.5 m @ 2.00 gpt Au; 63.0 m @ 1.89 gpt Au; 62.6 m @ 1.62 gpt Au (including 6.0 m @ 7.72 gpt Au); 24.5 m @ 3.18 gpt Au; 12.0 m @ 4.18 gpt Au; 29.0 m @ 3.16 gpt Au; 42.0 m @ 3.05 gpt Au in Camino Rojo Sulphides infill, further 8.5 m @ 3.52 gpt Au, 26 gpt Ag, 0.26% Cu, 3.6% Zn; 3.3 m @ 4.54 gpt Au, 7 gpt Ag, 0.06% Cu, 5.5% Zn; 1.5 m @ 15.4 gpt Au, 7 gpt Ag, 0.04% Cu, 4.4% Zn in the Camino Rojo Sulphides Deep Extension zone, and 10.5 m @ 0.69 gpt Au (including 1.5 m @ 4.02 gpt Au); 3.3 m @ 0.94 gpt Au; 1.5 @ 2.72 gpt Au; 1.3 m @ 61.2 gpt Au in the Guanamero zone of the Camino Rojo Regional Exploration. Polymetallic Au-Ag-Zn massive to massive sulphide mineralization has been confirmed in holes testing below the Caracol Formation hosted sulphides.  
  • Aztec Minerals Corp. received permits for a planned two-stage reverse circulation (RC) drilling program at its Cervantes project in Sonora. The first stage is to commence on Q3 2023 utilizing information gathered on the mapping and sampling of 4,600 m of roads. The quartz-feldspar porphyry is more extensive than the feldspar porphyry, and many of the sediments are less continuous and often as xenolithic rafts and roof pendants over the intrusive rocks. There is widespread phyllic alteration, minor potassic alteration as secondary biotite and zones of tourmaline mineralization; with gold showing positive relationship with vein intensity and silicic and phyllic alterations, and inverse relationship with argillic alteration. Au has strong correlation with As, Cu, Bi, Ag and W. With Mo being strongly distal. A marked Cu anomaly to the northeast associated with tourmaline and secondary biotite alteration. The focus is “to continue to define the open pit, heap leach gold potential of the porphyry oxide cap at California, test the down dip extensions of the silicic-phyllic alteration in the Qfp intrusive for deeper copper-gold porphyry sulfide mineralization underlying the oxide cap, and test for extensions of the California North target.”
  • Discovery Silver Corp. provided a project update on its Cordero project in Chihuahua. The company is to initiate the environmental permitting (Manifiesto de Impacto Ambiental, or MIA) process with the submission to SEMARNAT (Environmental regulator), and also “recently secured the surface rights that correspond with the planned open pit and key infrastructure locations at Cordero as well as a significant volume of water rights ….. Discovery also recently engaged M3 Engineering & Technology Corp to complete a technical review of the scope and cost to source water from existing water treatment plants in the region …… An impact assessment study and power installation study by Mexican electrical infrastructure authority CENACE were delivered earlier this year, with confirmation that there is sufficient capacity in the existing power grid to supply the Project with power for operations at peak throughput levels”. The company is also working on the front-end engineering design work for the feasibility study (FS), a resource update, metallurgical test work, process design, mine planning, geotechnical work and tailings study.

ON DEALS AND CORPORATE ISSUES             

  • Excellon Resources Inc. updated on the previously announced La Negra mine acquisition in Queretaro, from Orion Resource Partners. Excellon is focused on a successful completion of the C$10 M in gross proceeds financing, “but in parallel is reviewing potential operating scenarios that would allow Excellon to close on a lower level of initial financing that supports initiating advancement of La Negra while also adequately capitalizing the Company’s broader business”. The company is also in discussions with the holders of convertible debentures and assessing interim financing options as well as divestitures, mergers, or spin-offs to provide near-term liquidity.
  • Impact Silver Corp. updated on its plans for the recently acquired Plomosas mine in Chihuahua. Restart of production is scheduled for the second half of 2023, with design capacity to be approached on the first half of 2024. Underground equipment is under maintenance and repairs, mill foundations are being replaced, and the ball mill and conveyor-crushing systems are being upgraded. A new tailings dam is in the design and permitting stage, while alternate electric power options under evaluation, as well as changes in mining methods and mineral processing. Underground stations for drilling are in preparation, while drilling permits have been submitted for the surface program. Plomosas has a current JORC resource of 215 K tonnes @ 13.5% Zn, 6.3% Pb, 34 gpt Ag in indicated resources and 772 K tonnes @ 13.1% Zn, 3.0% Pb, 19 gpt Ag of inferred resources at a 3% Zn cut-off.

Three companies released drilling assays from properties in Mexico during the week. Vizsla Silver’s results from the Panuco project, in Sinaloa, returned the highest gold and silver intercepts from the low to intermediate sulfidation epithermal mineralization in the veins of the district.

Other project with low to intermediate sulfidation epithermal mineralization with significant results is Santo Domingo Hostotipaquillo, in Jalisco. Stroud Resources presented the results from drilling during 2021 and 2022, of which the most relevant results, from the not previously released 2022 campaign, are in the table below. The project is adjacent to and part of the same mineralizing system present at GoGold’s Los Ricos South project.

Santo Tomás is a porphyry copper project in northern Sinaloa, not far from the border with Sonora and Chihuahua. The long copper intercepts by Oroco Resources are from the North Zone.

/ Gambusino Prospector / Leave a comment

By Jorge Cirett                                             

During the 17th week of the year (April 24th to April 30th, 2023), 17 companies working in Mexico released news on their work. Five companies informed on exploration on their properties, six companies informed on Q1 2023 or full-year 2023 production/financial results. Two companies announced the closing and opening of financing rounds. A company corrected assay information on a previously issued drill intercept; one other provided an update on its intention to sue the Mexican government under a NAFTA legacy claim regarding the lack of action to terminate an illegal blockade. ON MEXICO ISSUES, Canada’s ministry of International Commerce, Mary Ng, expressed the preoccupation of foreign investors on the incoming changes to the Mining Law. The Mining Law was passed on Saturday morning by the Senate, and is set to return discretionary powers to the State on mining concessions. ON EXPLORATION, in Sonora, Prismo Metals released assays from surface sampling at its Los Pavitos property; Regency Silver released good results from deep drilling at its Dios Padre project; Colibri Resource released results from drilling at Evelyn project. In Zacatecas, Radius Gold updated on exploration work at the Tropico property. ON MINING, Sierra Metals, Mag Silver, Santacruz Silver, Alamos Gold, Pan American Silver and Agnico Eagle released Q1 2023 production reports. ON FINANCING, Silver Viper closed a private placement for $3.3 M; Radius Gold is to raise $1.75 M. ON RESOURCES AND DEVELOPMENT, Oroco Resource corrected assay results from one hole, previously issued last week, from its Santo Tomás project in Sinaloa. ON DEALS AND CORPORATE ISSUES, Guanajuato Silver informed on managerial changes. Silver Bull is to sue the Mexican government if a deal is not reached on an incoming meeting regarding the lack of action by the government to terminate an illegal blockade on its Sierra Mojada project in Coahuila. Prismo Metals and Vizsla Silver formalized the joint technical committee to oversee exploration of the Panuco district in Sinaloa, with Peter Megaw, Craig Gibson and Jesus Velador as members. ON SOCIAL RESPONSIBILITY, no relevant news.

ON MEXICO ISSUES

  • The ministry of International Commerce of Canada, Mary Ng, expressed to Raquel Buenrostro, head of the Economy Secretariat (Secretaría de Economía) the preoccupation of foreign investors on the changes to the Mining Law, and the negative implications on North America supply chains.
  • The Senate Commission on Regional Development and Legislative Studies approved without changes, by the ruling party coalition senators of Morena, PT, PVEM and PES parties, the reforms to the Mining Law, National Waters Law, Ecologic Equilibrium Law, Environment Law, and the General Law for prevention and Comprehensive Treatment of Tailings in Matter of Mining and Water Concessions. Among the changes is the reduction of mining concessions validity from 100 to 80 years (under certain conditions), the instauration of an auction system by the government for mining concessions, establishing that the concession title is to be issued AFTER the environmental, labor, energy, social and any other federal permit needed have been received (Note by Editor. – Speaking of putting the cart before the horse).
  • On the changes to the Mining Law. (Note by editor) The reform to the Mining Law is directed to regain quasi absolute control of mining concessions by the government, establishing rules under which the concessions can be revoked on grounds of indigenous population, community issues, environmental issues and water scarcity, all on which the government plays the role of judge and party. This is part of a broader drive by the president to concentrate power in himself and his government coalition before the 2024 presidential elections.

ON EXPLORATION

  • Prismo Metals Inc. released assays results from 354 surface samples on its 5,289 hectare Los Pavitos project in Sonora. Results from Las Auras are up to 0.5 m @ 14.35 gpt Au, 1.0 m @ 12.25 gpt Au, while at Santa Cruz assays are up to 0.5 m @ 5.48 gpt Au, 269 gpt Ag; 1.5 m @ 1.0 gpt Au, 543 gpt Ag. “Las Auras is characterized by northwest trending veins and shears hosted in intrusions, while Santa Cruz is dominated by northeast trending veins that follow sedimentary bedding”. Drilling is expected to begin in Q2 2023.
  • Regency Silver Corp. released results from two follow-up holes from the last drilling round discovery at the Dios Padre project in Sonora. Seven holes have been completed for a total of 4,251 m, of which six have intersected the targeted “pyrite +/- specularite +/- chalcopyrite supported breccia zone that hosts Au-Cu mineralization”.

  • Prismo Metals Inc. signed a contract for a 2,500 m drilling program at its Palos Verdes project in the Panuco District in Sinaloa. “The drill program is designed to test the 65% of the strike length of the Palos Verdes vein that has not yet been drilled. It is believed that potential for a large ore shoot is present similar to the drilling accomplished by Vizsla Silver on their adjacent land package is present on Prismo’s concession. Previous drilling has intersected high grade mineralization with the best intercept of 2,336 g/t Ag and 8.42 g/t Au over a true width estimated at 0.8 meters within a larger mineralized interval with 1,098 g/t Ag and 3.75 g/t Au over a true width of 2.3 meters”.
  • Radius Gold Inc. provided an update on the Tropico target in Zacatecas. “Radius geologists identified an elliptical zone of intensely silicified hydrothermal breccias approximately 450 m x 250 m. Several of the outcrops and float blocks are composed of chalcedonic and opaline sinter. The Tropico breccia is hosted within finely bedded siltstones and dirty limestones …”. Radius has an access agreement with the local community and land owners, has completed the geological mapping, contracted CSAMAT and IP geophysical surveys and is preparing for drilling upon receipt of the permits.
  • Colibri Resource Corp. provided assays results from 1,062 m of core drilling in three holes and 1,205 m of reverse circulation drilling in five holes at its Evelyn project in Sonora.

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

/ Gambusino Prospector / Leave a comment

Regency Silver’s drilling results from from holes at its Dios Padre project in Sonora returned some excellent gold grades and good copper over long intervals. The intercepts are on sulfide bearing breccias that are common in the Santa Rosa de Yecora district in Sonora. The breccias are complex, present in many shapes and developed in the intrusive rocks, or more commonly, in the contact with the hosting intermediate volcanic rocks package. Other breccias in the district host copper-molybdenum, gold or silver resources, and at least in one property gold is being currently mined.

The Evelyin project is also in Sonora and is being explored by Colibri Resource. Gold mineralization is of orogenic style, and the company has been drilling several targets with a strong structural component, as is usual in this type of deposits. Undercover mineralization is being pursued also by drilling short holes to bedrock on the extensive cover present in the area.

Oroco Resource presented a corrected set of results for one hole from its Santo Tomás porphyry copper project in Sinaloa, previously released last week.

ON MEXICO ISSUES

  • On the proposed changes to the Mining Law. For the last two weeks there have been many declarations by mining industry members and representatives against many of the proposed changes. There is a widespread movement calling for open discussions of the many elements on this proposal that are to pose a grave threat to foreign and local investment on the industry, affecting a large population base and increased deleterious effects in the economy on the long run. The AIMMGM (Asociación de Ingenieros Mineros, Metalurgistas y Geólogos de México) is asking Congress to organize an open parliament on the subject to discuss the merits and negative implications of the proposed changes.
  • The Mexican federal government qualified Vulcan Minerals $1.9 billion compensatory demand as unfounded on its reply to Centro Internacional de Arreglo de Diferencias Relativas a Inversiones courtroom. Vulcan has been quarrying limestone in Quintana Roo for more than 30 years, and has been pointed by the government as the culprit of an ecological disaster.
