ON MEXICO ISSUE

  • Enrique Zorrilla, president of the Canadian Chamber of Commerce in Mexico stated that Canada has its eyes fixed on Mexico as an investment destination for its mining companies, mainly in exploration expenses to find new gold deposits. He declared that 35% of the capital invested by that country goes to the mining sector.
  • According to a recent report by the Ministry of Finance, Mexico values ​​its lithium deposits in Sonora at USD $602,000M. Although Mexico does not currently produce the metal, the finance ministry estimated that Sonora’s reserves could add about 0.3% to potential GDP in the medium term. While the ultra light white metal is usually extracted from rock or brine deposits, lithium in Sonora is mostly trapped in clays, from which it has not yet been extracted on a commercial scale.
  • In Mexico, only 33% of mines have access to a computer with an Internet connection to reduce accidents. Ericsson revealed that the use of tools such as telemetry, satellite geolocation, wireless sensors and remote operation help improve mining operations, because with them and with the speed of the 5G network, information can be obtained practically in real time.

An additional $9 M is budgeted for 28,500 m of drilling across the broader land package and further $5 M for ore control and definition drilling in the ELG open pit and underground. “The ELG mining complex…. is hosted in the Mesozoic carbonate-rich Morelos Platform, which has been intruded by Paleocene granodiorite stocks, sills, and dikes. Skarn-hosted gold mineralization is developed along the contacts of the intrusive rocks and the enclosing carbonate-rich sedimentary rocks…. The style of mineralization at Sub-Sill South is like Sub-Sill and ELD, and is characterized by gold, which is strongly associated with bismuth and variable amounts of silver and copper. Gold occurs in variably sulfidized, pyrrhotite-rich skarn, while silver and copper mineralization is controlled primarily by the degree of sulfidation of the host skarn. Mineralization is associated with retrograde alteration characterized by the occurrence of phlogopite, amphibole, chlorite, calcite and lesser amounts of quartz and epidote, and local magnetite”.

·        Pan American Silver Corp. released an updated mineral resource estimate for its La Colorada Skarn deposit in Zacatecas. The estimated indicated mineral resource totals 95.9 M tonnes containing 94.4 M Oz Ag, 2.7 M tonnes Zn, 1.2 M tonnes Pb, with the estimated inferred mineral resource totaling 147.8 M tonnes containing 132.9 M Oz Ag, 3.4 M tonnes Zn, 1.5 M tonnes Pb. A total of 234,000 m of drilling have been completed to date on the deposit. “The polymetallic skarn mineralisation is concentrated in three zones, which cover an area of 1,500 metres by 1,100 metres laterally, and a depth of between 600 metres and 1,900 metres below surface….

ON MEXICO ISSUES

  • LitioMx. The federal government operation of its newly created Lithium Mining Company (LitioMx) is still hazy, but the possibility has been raised that private companies might participate, also that the current Sonora governor might be involved, and a director has been named, which happens to be a relative of the presidency representative in the State (Although eager to advertise its different way of doing things, this government is making a great effort to replicate the worst practices of past governments).
  • Trapped Coal Miners. Blame put aside, the fate of the 10 trapped miners in Coahuila after the flooding of the coal mine on August 3 is almost defined, and the effort is now changing from rescue to body recovery, which might take months.

ON EXPLORATION

  • Prismo Metals Inc. received results from the Lidar survey carried out at its 5,289 ha Los Pavitos project in Sonora. “Mineralization at Los Pavitos consists of quartz veins and stockworks hosted in metasediments, in shear zones and parallel to foliation and crossing foliation”.

By Miguel A Heredia

During the 34th week of the year (August 22nd to August 28th, 2022), at least 16 press releases were announced by companies working in Mexico, and 7 news published by the media with seven commenting on Mexican issues, four communicating production and financial results, four disclosing deals and corporate issues, three reporting resources and developments of their properties, three announcing financial issues, and two informing on exploration results. ON MEXICO ISSUES, Colibri and Oroco reported the best drilling intercepts in Mexico on the fourth week of August, 2022. The government of Mexico announced, through a decree in the Official Gazette of the Federation, the creation of the state company Litio para Mexico (LitioMx). According to the Mining Chamber of Mexico (CAMIMEX), a total of 822 mining projects remain on hold and represent an amount of USD $959M.   Jaime Gutierrez Núñez, president of CAMIMEX stated that small-scale coal mining is like “the blood diamonds” of Africa. Mexico’s mining industry plans to invest USD $5.5B in 2022, 15.2% more than in 2021. Mining in Mexico grew by 7.1% in 2021 despite friction with the government. The governor of Durango, José Rosas Aispuro, considered unfair that the mining-metallurgical sector is one of the economic sectors with the highest tax burden in the country. In Mexico there are more than 1,209 mining projects that have been developed in 26 states of the Republic.  ON EXPLORATION, In Sonora, Colibri reported results from the second half of its Phase 1 drill program completed on its Evelyn project, and Tocvan announced latest drill results from its Pilar project.  ON MINING, Guanajuato Silver, Discovery Silver, Minera Alamos, and Orogen reported Q2, 2022 production and financial results from their Mexican operations.

ON MEXICO ISSUE

  • Colibri Resource Corporation and Oroco Resource Corp., reported the best drilling intercepts in Mexico on the fourth week of August, 2022. Details are shown in the table below:
·        The government of Mexico announced, through a decree in the Official Gazette of the Federation, the creation of the state company Litio para Mexico (LitioMx). The Government of Mexico created LitioMx as a decentralized public organism of the Federal Public Administration and coordinated by the Ministry of Energy, with its own legal personality and assets and with technical, operational and management autonomy. The objective of LitioMx will be the exploration, exploitation, benefit and use of lithium, located in national territory, as well as the administration and control of the economic value chains of such mineral.
·        According to the Mining Chamber of Mexico (CAMIMEX), a total of 822 mining projects remain on hold and represent an amount of USD $959M, which are still waiting for better conditions to be able to reactivate. Jaime Núñez, president of CAMIMEX stated that is essential to encourage exploration since unfortunately in the last seven years we have seen a decrease in investments in exploration, leaving several projects on standby.
·        Jaime Gutierrez Núñez, president of CAMIMEX stated that small-scale coal mining is like “the blood diamonds” of Africa, and that the Federal Electricity Commission (CFE) should certify where the mineral it buys comes from and its conditions.
·        Mexico’s mining industry plans to invest USD $5.5B in 2022, 15.2% more than in 2021, but according to the Mexican Mining Chamber (CAMIMEX), it will remain below the record figure of USD $8.04B seen in 2012 amid difficult conditions. Growing security problems, a high tax burden and the government’s decision to stop granting concessions for projects have prevented investments in the sector from increasing faster, said CAMIMEX head Jaime Gutiérrez.
·        Mining in Mexico grew by 7.1% in 2021 despite friction with the government. According to CAMIMEX’s annual report, this increase positioned it as the only productive activity that recovered and even exceeded the fall of 2020, when the covid-19 pandemic initially stopped its operations because the government did not consider it “essential activity”. Even without tax incentives, the mining sector presented an increase in its contribution to the gross domestic product (GDP) going from 2.3% in 2020 to 2.5% in 2021, and an annual advance in the proportion of industrial GDP from 8.3% to 8.6% in the same period.
·        The Governor of Durango, José Rosas Aispuro, considered unfair that the mining-metallurgical sector is one of the economic sectors with the highest tax burden in the country, even though it is an enabler that prevents the migration of people in the communities where it develops its production processes, for job creation and social benefits. Mining Entrepreneurs stated that mining generates jobs and is one of the industries that pays the most taxes, since in 7 years it has contributed more than MXP $240,000M (approximately USD $12B) in taxes and other rights.
·        In Mexico there are more than 1,209 mining projects that have been developed in 26 states of the Republic, in which 406,179 jobs have been generated and a production value that already exceeds MXP $334,782M (approximately USD $16.7B). Among the main minerals extracted from these deposits are gold, copper, silver, zinc, iron, molybdenum, lead, fluorite, among others. For its exploration and exploitation, in 2021 alone, investments have been made for more than USD $4,810M and more than USD $5,538M are expected by the end of 2022. Of the 1,209 mining projects that exist in Mexico, 286 are in Sonora, Chihuahua has 160 and Durango has 128, which positions them as the entities with the greatest economic benefit thanks to mining concessions. Of the total number of projects, 749 correspond to precious metals; 180 to polymetallic minerals, 167 to copper, 71 to iron ore and the remaining 42 to other metals and minerals. According to the Mexican Mining Chamber (CAMIMEX), there are currently a total of 263 projects in the exploration stage, 76 in production, 39 in the development stage, while 822 projects are being postponed and 9 operations are reported as closed. However, the agency assures that, since the start of the current administration, the federal government has stopped granting permits or concessions for the exploration and development of new projects, since so far more than USD $959.7M dollars have not been invested. .
ON EXPLORATION
·        Colibri Resource Corporation reported results from the second half of its Phase 1 drill program completed on its Evelyn project, Sonora, and included 3,101m of RC drilling completed in 22 holes. In total, Phase 1 consisted of 6,223m of RC drilling in 42 holes.  Highlights include hole EVE22-042 with 0.17 g/t Au over 86m, including 0.32 g/t Au over 22m; hole EVE 22-043 with 0.92 g/t Au over 3m; hole EVE22-046 with 1.94 g/t Au over 2m, including 3.36 g/t Au over 1m; hole EVE22-044 with 0.63 g/t Au over 6m; hole EVE22-036 with 1.3 g/t Au over 1m; hole EVE22-033 with 1.92 g/t Au over 1m; hole EVE22-030 with 0.13 g/t Au over 87m, including 0.34 g/t Au over 8m; hole EVE22-029 with 1.39 g/t Au over 5m; and hole EVE22-028 with 0.13 g/t Au over 19m.

ON MEXICO ISSUES

  • No Relevant News.

ON EXPLORATION

  • Silver Spruce Resources Inc. along with Colibri Resource Corp. completed its phase 1 drilling program at the 1,057 ha Diamante project in Sonora. The 2,005 m reverse-circulation program in 19 holes, up to 135 m in depth, covered the La Prieta, and Pillado targets. “Mineralization is reported visually as pyrite, arsenopyrite, chalcopyrite, sphalerite, argentiferous galena, argentite, hematite and probable metal oxides, carbonates and sulphates, including copper carbonate (malachite), copper sulphates and plumbojarosite”.
  • Vortex Metals Inc. provided an update in exploration of its Riqueza Marina and Zaachila projects in Oaxaca. The late David Jones identified this area in the early 2000’s …”Copper-gold mineralization within both the Riqueza Marina and Zaachila projects is associated with geologic processes operative in the Late Jurassic to Middle Cretaceous within a back-arc sequence of bi-modal volcanics and volcaniclastics deposited on the sea floor. Early exploration conducted by Dave Jones identified several copper and gold anomalies over a broad area but clearly associated with specific rocks, i.e. exhalite, rhyolite debris aprons or breccia. These associations prompted the identification of a geologic environment which incorporated these features. The Volcanogenic Massive Sulfide (VMS) model incorporates the geologic and geochemical features observed to date”.
  • Kootenay Silver Inc. informed significant progress has been made on the 15,000 m drilling campaign at Columba, in Chihuahua. The current program will test extensions of the F, D, B and JZ veins and exploratory step-outs on other prospective veins. The V vein has been traced for over 700 m of strike and 200 m of depth with an average of 2 m in width, the D vein has been hit along 430 m of strike and 340 m of depth with an average of 6.9 m in width.
  • Tocvan Ventures Corp. informed that seven reverse circulation drill holes for a total of 1,382 m have been completed on the phase III drill program at Pilar, in Sonora.
  • Alien Metals Ltd. updated on exploration work at its San Celso and Donovan 2 projects in Zacatecas. Three holes totaling 201 m were drilled at San Celso and four holes at Donovan 2 for 410 m. No significant intersections were returned for San Celso. At Donovan 2, a 1.87 m interval returned 0.33% Cu, although the recovery was in the 15-20% range. A weak Zn anomaly correlates with a similar zone in a previous hole.
  • Mammoth Resources Corp. provided results from four holes at its Tenoriba project in Chihuahua. The four holes totaled 388.95 m brining the total to 2,623.55 m in 21 holes.
