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:

· 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 MEXICO ISSUE
- Arcelor Mittal announced that the strike broke out by the National Union of Mining, Metallurgical, Steel and Similar Workers of the Mexican Republic will affect the economy of Michoacan and the metallurgical sector. The strike will have an impact and serious consequences in the short, medium and long term on labor and economic stability in the Lázaro Cárdenas region, in the state of Michoacán, in the production chain and in the country´s economy.
- With strike, Napoleón Gómez Urrutia and his miners managed to jump the “cap” in the payment of utilities. With the work stoppage carried out by mining workers from section 271 in Lázaro Cárdenas Michoacán to the company Arcelor Mittal Mexico, on June 15, they managed to eliminate the “cap” on the payment of utilities that was included with the labor reform in April of 2021. This is not the first union organization to take action to pressure the company to grant a higher amount in the payment of utilities.
- The first International Mining Women’s Day was commemorated. This June 15 marks the first World Mining Women’s Day as an initiative of the International Organization “Women in Mining”. Engaging the Women Mining Community, the International Day of Women in Mining will showcase the experiences, hopes and aspirations about the industry, and celebrate the personal achievements of women in the industry.

The Mining and Exploration News in Mexico: Highlights on the Fourth Week of May, 2021

By Jorge Cirett
During the 21st week of the year (May 24th to May 30th, 2021), at least 33 press releases were announced by companies working in Mexico. To note, seven companies posted exploration advances on their properties, three presented mining related news, seven posted on financing (C$6M, $60 M, C$5 M, C$10 M, $2.6 M, $C$11.5 M) and one on share distribution, six more on project development or resource definition and two posted on corporate issues. ON MEXICO ISSUES, CanCham complained on the lack of clear policies and opacity on the rule of law that are affecting Canadian investments in Mexico. The push from the Mexican government to create an institution to manage the lithium industry from the optics of sovereignty sees opposition from the mining industry, and reality. Camimex released a list of mining investments to be realized in the next few years, amounting to several billion dollars. ON EXPLORATION, in Sonora, Ridgestone Mining applied for drilling permits at Rebeico. Tocvan Ventures released results from drilling at Pilar. In Chihuahua, Kootenay Silver released high-grade results from drilling at Columba. In Durango, Mithril Resources, updated on drilling at Copalquin. In Sinaloa, Riverside Resources released surface sample results; Vizsla Silver informed on geophysical results supported by drilling, and more surveys to come; Brigadier Gold discovered bulk tonnage copper mineralization in trenching of soil anomalies. ON MINING, Impact Silver and Telson Mining presented Q1 2021 results. Magna Gold informed it has exceeded 3 M man-hours of work without lost-time incidents. ON FINANCING, Silver Bull Resources is to distribute 34.2 M shares of Arras Minerals among its shareholders. Six companies informed on financing rounds: Silver Viper Minerals (C$6 M), Vizsla Silver ($60 M), Reyna Silver (C$5 M), Sable Resources (C$10M, Defiance Silver (C$11.5 M) and Mammoth Resources ($2.58 M). ON RESOURCES AND DEVELOPMENT, Prime Mining released drilling results from Los Reyes. GR Silver Mining reported near surface drill results from Plomosas. GoGold Resources released drilling results from the Casados deposit at Los Ricos North. Discovery Silver released results from 12 drill holes targeting high-grade vein trends at Cordero. Sailfish Royalty filed a technical report with a new resource estimate for Gavilanes. Discovery Silver updated on exploration at Cordero, with 75,000 m of drilling completed on 178 holes, and four drills continuing the phase 2 program. Golden Tag announced the discovery of a shallow zone of epithermal mineralization at San Diego. ON DEALS AND CORPORATE ISSUES, Mexus Gold informed Fresnillo PLC is reviewing its Santa Elena mine. Riverside Resources announced BHP is funding a third year of generative work in Sonora. ON SOCIAL RESPONSIBILITY, Peñoles and Fresnillo PLC informed on their policies and programs to aid in education on a wide range of communities. Minera San Xavier informed Cerro San Pedro in San Luis Potosi has been declared as “Cyanide Free Site” by the International Cyanide Management Institute.
ON MEXICO ISSUES
- CanCham (Cámara de Comercio de Canadá en México) pointed out that the lack of clear policies and the opacity on rule of law is affecting Canadian investments, which show an 18% decrement in the last year, holding the investment of thousands of millions (Mexican number notation) of dollars in the energy, mining, pharmaceutical and agricultural sectors. These remarks were expressed by Enrique Zorrilla, Cancham’s president, in the meeting between the Commerce ministers of Mexico, Canada and the United States.
- Mexico is preparing its strategy to develop the lithium market. The federal government intends to become a lithium producer by controlling several deposits, Bolivia’s advice and a commerce treatise to facilitate establishing an electric battery factory. The current government senate fraction is preparing a proposal to create the Instituto Nacional del Litio. (Lithium National Institute) and to declare lithium as Nation’s exclusive property (Note. – This federal initiative push misses the point that so far there is not a single lithium mine in Mexico, that its lithium in brines potential is limited at best, and that the economics of lithium extraction from clays -like in the Bacanora Lithium’s deposit in Sonora- is not yet clear).
- Fernando Alanís, president of Camimex (Cámara Minera de México) informed that lithium deposits in Mexico have a very low grade, and lack the technology for its extraction, reason for which the country is far from becoming a world power in lithium production. Lithium presents in three kind of deposits: hard rock (pegmatites), brines (from salt lakes) and clays. Rock and brine lithium extraction accounts for 100% of the world production, whereas the extraction of lithium from clays is very energy intensive and expensive, not having a single producing mine in the entire planet.
- Camimex released a table with the Mexican Mining Developments programmed for the next few years, same that reach US$7,820 Million in investment (Mexican number notation, equivalent to US$7.8 billion).

ON MEXICO ISSUES
- Mining municipalities in San Luis Potosi demand to receive the Mining Fund. The municipality of Charcas, in San Luis Potosi, presented a legal complaint to the Supreme Court to avoid the use of these funds (gathered by the payment on a royalty from mining proceeds) for programs unrelated to mining. The municipality president, Manuel López Lara, said these resources are needed to provide vital infrastructure to the community, and that they are awaiting a favorable resolution by the Supreme Court.
ON EXPLORATION
- One World Lithium Inc. appointed Montgomery and Associates as operator for its upcoming drill programs on its Salar del Diablo lithium brine project in Baja California. Initially four diamond holes are to be drilled to 600 m depth to collect 20 groundwater samples at specified depths using a depth specific packer system.
- Minaurum Gold Inc. released further drill results from its Alamos Silver project in Sonora. With the latest results Minaurum has now tested 14 of the 20 veins systems in the project. Highlighted recent results comprise 3.80 m @ 415 gpt Ag, 2.68 gpt Au, 1.37% Cu, 6.2% Pb, 9.2% Zn (including 0.95 m @ 1,566 gpt Ag, 6.72 gpt Au, 4.48% Cu, 9.3% Pb, 10.1% Zn); 0.95 m @ 425 gpt Ag, 0.32% Cu, 3.2% Pb, 1.3% Zn; 1.95 m @ 261 gpt Ag; 0.90 m @ 337 gpt Ag; 0.90 m @ 307 gpt Ag; 1.05 m @ 134 gpt Ag, 0.31% Cu, 1.2% Pb, 3.9% Zn. Minaurum reports high grade silver intercepts in 10 of the 14 veins drilled to date, and plans to drill six more vein systems before beginning follow-up drilling on veins that have the potential to host volumes of high-grade mineralization similar to that of the historic Quintera and Promontorio mines.
- Canasil Resources Inc. presented a review of its main projects in central Mexico. At La Esperanza, in Zacatecas, there is a series of epithermal veins on a 15 km long corridor, with drilling at the La Esperanza vein returning up 11.23 m true width (TW) @ 219 gpt Ag, 0.74 gpt Au, 0.9% Zn, 0.4% Pb (including 1.11 m @ 2,281 gpt Ag, 6.39 gpt Au, 2.2% Zn, 1.2% Pb. At Salamandra, in Durango, a rhyolite dome intruding sedimentary rocks has returned drill intercepts of up to 9.5 m @ 102 gpt Ag, 0.5% Zn; 10.0 m @ 71 gpt Ag, 3.5% Zn, 1.3% Pb; 7.89 m @ 166 gpt Ag, 1.2% Cu, 1.2% Zn, 0.6% Pb (including 2.30 m @ 393 gpt Ag, 3.6% Cu, 2.8% Zn, 0.4% Pb). At Nora, in Durango, samples on epithermal veins have returned up to 1.0 m @ 1.98 gpt Au, 514 gpt Ag, 1.03% Cu, 3.3% Zn, 4.4 % Pb. At Vizcaino, in Zacatecas, the gold-anomalous Pamplona vein is 1 to 12 m in width over 2 km of length, with chalcedonic quartz hosted in rhyolites.
- Megastar Development Corp. reported assay results from surface sampling at its Yautepec property in Oaxaca. Results from a sinter zone and a bounding quartz vein of 162 samples returned up to 308 gpt Ag, 1.07 gpt Au, 99 ppm Cu, 464 ppm Pb, 548 ppm Zn, 102 ppm Mo, 92,600 ppm (9.26%) As, 307 ppm Sb. These high numbers are very encouraging on a high-level epithermal system like the one exposed at this project.
ON MINING
- Mexus Gold US. has piled 4,000 tons @ 2.8 gpt Au on the heap for leaching at its Santa Elena mine in Sonora (not to mistake for First Majestic’s Santa Elena mine, also in Sonora).
