ON MEXICO ISSUE
- Mexican Senators approved the Federal Law of Rights 2025 in particular and now began the analysis and discussion of the Federal Income Law to increase its collection during 2025 in activities such as mining, immigration services and use of Protected Natural Areas, and also start charging aviation schools and cruise passengers. In the Federal Rights Law 2025, the rate of special mining rights is increased for the following year from 7.5 to 8.5% on the income obtained by the holders of mining concessions derived from the alienation or sale of the extractive activity. In addition, the rate of extraordinary mining rights is raised from 0.5 to 1.0% on the income obtained by mining concessionaires derived from the sale of gold, silver and platinum. The Morena senator, Ochoa Fernández, explained that these increases in mining rights rates are made to address the increase in international metal prices. The fees for the use or exploitation of the 181 Protected Natural Areas (ANP) at the federal level are also raised by 100%.
- Federal government proposed an increase in mining rights in the Federal Rights Law 2025, which is about to be approved in the Senate of the Republic. It comes after in 2024 its collection has fallen by almost a third. In January-September 2024, the government collected MXP $6,205.60M (approx USD $305.7M) for special mining rights and extraordinary mining rights, according to the latest quarterly report from the Ministry of Finance and Public Credit (SHCP) to the Congress of the Union, while in the same period of 2023, the collection of said rights amounted to MXP $9,177.71M pesos (approx USD $452.1M), so this year collection has fallen 32% in real terms. The SHCP proposes to increase the special mining right rate from 7.5 to 8.5% on the income obtained by the holders of mining concessions derived from the alienation or sale of the extractive activity. In addition, it seeks to increase the rate of extraordinary mining rights from 0.5 to 1.0% on the income obtained by mining concessionaires derived from the sale of gold, silver and platinum. For the special right on mining, the federal government has collected MXP $5,422.70M (approx USD $267.1M) in the first nine months of 2024 (an annual drop of 34%), while for the extraordinary right on mining it has obtained MXP $782.9M (approx USD $38.6M) (17% less than in 2023). In addition to these rights, in Mexico two others are charged for this activity: the right for mining concessions and assignments, and also the additional right on mining. No increases are proposed for these two rights. In total for the four rights, the federal government has collected MXP $8,981.80M (approx USD $442.5M) at the end of September 2024, a drop of 26% annually. In the Federal Law of Rights 2025, which will be discussed today in the plenary session of the Senate of the Republic together with the Federal Income Law, the rights charged for immigration services, as well as for the use and use of Protected Natural Areas. The Morena deputy, Alfonso Ramírez Cuéllar, has assured that with these reforms to the Federal Rights Law, “a budget of more than MXP $140,000M (approx USD $6,896.6M)” will be obtained with respect to what is collected from rights in 2024.
- Impact Silver Corp., Silver Storm Mining Ltd., Heliostar Metals Limited, and Torex Gold Resources Inc., reported the best drilling intercepts in Mexico on the first week of December, 2024. Details are shown in the table below:
ON EXPLORATION
- Kingsmen Resources Ltd., identified a significant new drill target called Saddle at its 100% owned Las Coloradas project in Chihuahua. It is part of its ongoing field reconnaissance in preparation for an upcoming drill program. The Saddle target is situated between two magnetic highs, where a deep wedge of volcanics and sediments, along with veins and structures, are believed to underlie surface precious metal anomalies. The area revealed anomalous values of gold and silver, along with other metals such as copper, lead, and zinc, associated with quartz-carbonate veins. This geochemical anomaly is both within and adjacent to the targets indicated by geophysical surveys. The geophysical data suggests the potential for discovering significant blind mineralization in this area.
ON MINING
- Sierra Metals Inc., provided production and cost guidance for 2025 for its Bolivar mine in Chihuahua. The company expects to produce between 25.1M-27.4M Lb Cu, 680K-740K Oz Ag, and 7.4K-8.1K Oz Au at cash and AISC of $2.64-$2.77 and $3.45-$3.62 per Lb CuEq respectively.
- Minera Alamos Inc., reported production results from its Santana mine in Sonora (All currency reported is Canadian dollars). In Q3, 2024, the company staked 3,800 Oz Au on the leach pad. As of September 30, 2024, recoverable gold inventory on the leach pad totaled 8,199 Oz Au. Subsequent to the quarter end, mining and stacking activities continued to increase with a total of 1,788 Oz Au mined in the month of October, of which 1,585 Oz Au were stacked on the heap leach pad with the remainder stockpiled for crushing prior to placement on the heap leach pad. The average grade of mineralized material mined during Q3-2024 (and October) was 0.60 g/t. The company also reported deferred revenue of $3.45M in exchange for the sale of 1,000 Oz Au; loss from the re-start of mine operations of $436.2K; and cash and cash equivalents of $5.96M.
- Gold Resource Corporation provided an update on its operational and liquidity status as of December 2, 2024. The company reported improvements in production at the Don David Gold Mine, Oaxaca during November, attributed to effective mine planning and resolution of previous operational issues. This led to slightly better than break-even cash flow for the month, aided by high metal prices and a favorable exchange rate. Despite these improvements, the company expressed concerns about its available cash balance and indicated that additional funding is necessary for mining equipment, mill upgrades, and working capital to support future production in the Three Sisters and Splay 31 areas. Without this capital, the company anticipates challenges in maintaining break-even cash flow beyond the first quarter of 2025. Additionally, Gold Resource Corporation identified an overpayment of approximately USD $3.8M in Mexican taxes for 2023 and has submitted a refund request, expected to be processed in 2025, although the timing remains uncertain.
ON FINANCING
- Fortuna Mining Corp., announced progress on its share buyback program. It has repurchased an aggregate of 6,402,640 common shares on the open market of the New York Stock Exchange. Shares were repurchased at a weighted-average price of $4.77 per common share for a total gross amount of $30,529,066, excluding brokerage fees; these shares will be cancelled. To date, the Company has repurchased 41.88 percent of the 15,287,201 shares it is authorized to repurchase under the Normal Course Issuer Bid (San Jose mine, Oaxaca).
- DynaResource Inc., announced the successful repayment of its temporary additional credit line (TACL) with Ocean Partners Holdings Limited. The company recently fulfilled its obligation to repay USD $4M TACL due November 30, 2024, payable alongside USD $5.85M outstanding balance of the revolving credit line (RCL). Upon full repayment of the TACL and RCL, the maximum principal amount under the RCL was increased to USD $12.5M. The company has drawn down USD $9.85M, with interest accruing at the same rate as the ongoing and outstanding RCL with Ocean Partner (San Jose de Gracia project, Sinaloa).
- Minera Alamos Inc., closed a bought deal private placement for gross proceeds of CADS $8,499,900 by selling 28,333,000 common shares at a price of CAD $0.30 per common share. Net proceeds will be used to fund the expansion and development of its Santana open-pit, heap-leach mine in Sonora, to fund the exploration and development activities at its Cerro de Oro Project in northern Zacatecas and for working capital and general corporate purposes.
ON RESOURCES AND DEVELOPMENT
- Silver Tiger Metals Inc., commenced an underground drilling program at its El Tire project in Sonora, focusing on high-grade vein, sulfide, and shale zones. The company aims to deliver a Preliminary Economic Assessment (PEA) for the underground component by the first half of 2025. This initiative follows the successful completion of the near-surface open pit portion of the project, highlighting the significant exploration potential in the area, which is estimated to contain 10 to 12M tonnes at 225 to 265 g/t AgEq, equating to 73 to 100M Oz AgEq.
- Oroco Resources Corp., provided a corporate update regarding its Santo Tomas project in Sinaloa, highlighting ongoing preparations for Phase 2 technical work. The project has shown a compelling economic case with a 22.6-year Life of Mine and a post-tax NPV of USD $1.48 B. The company is closely monitoring legal and regulatory changes in Mexico, particularly under the new administration of President Claudia Sheinbaum, to ensure continued support for its mining activities. Key initiatives include defining community investment opportunities, expanding technical programs for updated resource estimates, specifically including elevated resource classifications and an expanded Indicated Resource at South Zone sufficient to support a PFS-level technical report, and enhancing shareholder engagement. The update emphasizes Oroco’s positive outlook for the project’s future development and its potential as a capital-efficient, large-scale copper project.
- Impact Silver Corp., released results from its ongoing drill program on the Tres Amigos Zone at its Plomosas mine in Chihuahua. Drilling highlights are shown in the table below:
All these Tres Amigos area drillholes are beyond the current active mining area and lie outside the JORC mineral resource. The Tres Amigos Zone remains open for exploration and drilling is continuing.
- Silver Storm Mining Ltd., announced results from five holes drilled at the Norte-Sur Zone, within the Quebradillas mine within its Parrilla mine in Durango. Drilling highlights are shown in the table below:

ON MEXICO ISSUE
- Industrias Peñoles S.A.B de C.V., reported that its Tizapa mine in the State of Mexico, suspended operations due to strike call promoted by the National Union of Mining, Metallurgical, Steel and Similar Workers of the Mexican Republic. The facility was the subject of scrutiny by the authorities in recent months, due to a request from the United States to review a possible violation of labor rights, within the framework of the North American trade agreement, USMCA, which the company denied. The company stated that it “fully” complies with the obligations of the labor agreement and local labor laws, and noted that “it will adhere to the corresponding legal and administrative procedures to resolve this conflict”.
- In Mexico, The Constitutional Affairs Committee of the Chamber of Deputies agreed to discuss the initiative to ban open-pit mining, which set off alarms in the extractive industry, which demands an open parliament before approving a reform that they warn will generate shortages of essential resources in North America, in addition to having a fiscal impact of around MXP $30 billion in contributions to the Treasury by companies. Pedro Rivero Gonzalez, President of the Mexican Mining Chamber (CAMIMEX) stated that open-pit mining is very important for the country, not only because 60% of production in Mexico comes from this extractive technique, but also because the prohibition of this activity compromises more than MXP $30 billion in various fiscal contributions for the federal government, as well as a possible economic contraction estimated at MXP $250 billion annually (-1% of the National GDP).
- Mining companies in Mexico are concerned about their production is affected by the ban on open-pit in the country. The Mexican Mining Chamber (CAMIMEX) revealed that if this initiative is approved, the mineral that would be most affected is copper because so far there are few deposits in Mexico that can be exploited underground. Almost 70% of the copper produced in the country is by open-pit. In this regard, analysts stated that the losses for the country could be double, since it is estimated that the price of copper will increase by up to 40%, which means that the profitability of companies such as Grupo México, Minera Frisco, Nemisa and Capstone Copper will see their income affected. According to CAMIMEX, banning open-pit mining will generate an economic contraction of 250 billion pesos and it estimated that more than a million formal jobs will disappear, a fact that worries companies that have exploration projects in Mexican territory.

ON MEXICO ISSUE
- German Larrea, owner of Grupo Mexico, announced that it is among several companies that are interested in acquiring a copper mine of First Quantum Minerals in southern Spain. First Quantum began a process to sell its Las Cruces mine in southern Spain in December after the sudden closure of the Panama copper mine left the company against financial uncertainty. The Las Cruces mine would give Grupo México, the conglomerate controlled by Mexican billionaire Germán Larrea, another opportunity to expand in Europe after he failed to acquire a different Spanish copper mining complex in 2021. Copper assets have attracted the interest of mining companies that expect demand to increase as a result of the energy transition, and the upward perspectives have already caused an increase in negotiations.

Hydrothermal breccia
By Miguel A Heredia
During the second week of the year (February 08th to February 14th, 2021), at least 28 press releases were announced by companies working in Mexico and 11 news published by the media, with nine disclosing deals and corporate issues, six announcing financial rounds, six reporting on resources and development of their mine operations, six commenting on Mexican issues, five informing on exploration results, five discussing social issues, and two communicating production and financial results. ON MEXICO ISSUES, Environmental, social and corporate governance (ESG) criteria are a key factor in Accendo Banco’s investments in Mexico’s mining sector, according to its CEO, Javier Reyes. Mining in Mexico registered a 19.5% rebound during October, 2020, according to the Monthly Indicator of Industrial Activity by Federal Entity (IMAIEF) released by the Institute National Statistics and Geography (INEGI). Tatiana Clouthier, head of the Secretariat of Economy declared that mining in Mexico must become a sustainable activity that prioritizes three issues: economic, human and nature. The energy policies that the federal government is following are already affecting the development of projects for the self-supply of energy by the mining sector. Experts detailed the main challenges that the Mexican mining sector will face in 2021, the year in which the industry is expected to play a leading role in the economic reactivation after confinements. Almost a year of delay accumulates the USD $60M of Chinese investment to construct the industrial park at Guadalupe, Zacatecas.

ON MEXICO ISSUES
- Environmental, social and corporate governance (ESG) criteria are a key factor in Accendo Banco’s investments in Mexico’s mining sector, according to its CEO, Javier Reyes. Investment deals recently advanced by the bank include a proposed USD $12M loan to finance construction of Telson Mining’s Tahuehueto gold mine in Durango. Candelaria Mining also signed a USD $9M loan agreement with Accendo in June 2020 for the construction of its Pinos gold project in Zacatecas. Lastly, Accendo signed a strategic alliance with Vancouver-based Empress Royalty in August last year. The agreement aims to acquire royalties, cash flows and other investments in Mexico’s mining sector.
- Mining in Mexico, registered a 19.5% rebound during October, 2020 according to the Monthly Indicator of Industrial Activity by Federal Entity (IMAIEF), released by the Institute National Statistics and Geography (INEGI).
- Tatiana Clouthier, head of the Secretariat of Economy declared that mining in Mexico must become a sustainable activity that prioritizes three issues: economic, human and nature. On the other hand, Clouthier highlighted the work that mining companies of all levels have done to accelerate the economic reactivation of the country. “The Gross Domestic Product (GDP) that is generated through mining is about 3.2% and we are pleased to see that these numbers can continue to move in favor of the economy and Mexican families,” she said. “In the Ministry of Economy we have already invited large, medium and small companies and associations that are linked to this issue to be able to find solutions, to be able, within the framework of the law, to activate what we have to activate for this task it can be managed better and it can yield better results in favor of our country”, she assured.
- The energy policies that the federal government is following are already affecting the development of projects for the self-supply of energy by the mining sector. According to data from the Mexico Mining Chamber (CAMIMEX), electricity for this industry is 33% and up to 350% more expensive compared to other countries, which increases its production costs. That is why the mining companies have decided to invest and develop electricity generation projects, which range from combined cycle plants to solar or wind farms. Despite this, many of these plans have been affected by current policies on energy and the action of regulatory bodies, such as the Energy Regulatory Commission (CRE), which reduced the granting of permits to a minimum. President of CAMIMEX assured in recent days that half of the energy consumed by the mining industry is under the self-supply model.
- Experts detailed the main challenges that the Mexican mining sector will face in 2021, the year in which the industry is expected to play a leading role in the economic reactivation after confinements. The main problems for the sector are the current health complications associated with the COVID-19 pandemic, a series of directly or indirectly legislative proposals with potential negative impacts on the mining sector such as the direct initiatives to try to raise taxes at the state of federal level or indirect initiatives as the elimination of the outsourcing or initiatives of the electricity industry. Deputies of Mexico received in January a proposal from a legislator of the ruling party Morena aimed at reviewing the fees paid for mining concessions. It proposed replacing per hectare fees with potentially much higher charges linked to production. Another problem is the “profound ignorance” of the importance of the mining industry.
- Almost a year of delay accumulates the USD $60M of Chinese investment to construct the industrial park at Guadalupe, Zacatecas. This delay has been caused by the COVID-19 pandemic.

ON RESOURCES AND DEVELOPMENT
- Bacanora Lithium plc., commenced initial site activities at its Sonora Lithium project in Sonora. Bacanora engaged a local specialist ecological service company to rescue and remove surface vegetation and topsoil in the area proposed for the construction of the processing plant. The company is also upgrading the main access road for providing access to heavy equipment to commence the bulk site earthworks later in the year.
- Excellon Resources Inc., provided an update on ongoing exploration at its Platosa mine in Durango. The company is drilling regional targets such as Jaboncillo and the PDN areas, as well as drilling the Platosa extensions and Platosa Underground to support resource definition and expansion. At Jaboncillo zone, located 11 km north of Platosa mine, Excellon identified in a previous drilling campaign a 1.2km length gossans mineralization. The current drilling program is targeting the source of these gossans and the existence of massive sulphides. At PDN zone, located 2 km north of Platosa mine, it is testing a large 800m by 60m target generated with multiple sets of geophysical data, surface mapping and sampling. This target is interpreted as a deeper skarn related to the Rincon del Caido skarn discovered in 2012 where a previous drill intercept encountered 132 g/t Ag, 3.1% Pb, 1.7% Zn, and 0.075 g/t Au (278 g/t AgEq) over 55.5m. At the 10-20 target, the company has been conducting drilling surface to add mineralization over approximately 300m of strike with a vertical extent of 30-40m. This zone has potential to significantly increase the current 800m by 600m mineralized footprint of the Platosa mine. At Platosa mine, Excellon is conducting underground drilling to define mineralization ahead of mine development and add mineralized inventory in areas not adequately tested by surface drilling. This underground drilling program follows up on previous drilling of the Pierna and NE-1 mantos and depth extensions of the 623 and NE-1S mantos.
- GR Silver Mining Ltd., released underground and surface drilling results from its Plomosas project in Sinaloa. Significant mineralization was encountered in hole PLI-20-05 with 2.63 g/t Au, 39 g/t Ag, 0.2% Cu, 0.2% Pb, and 0.1% Zn over 4m, including 8.95 g/t Au, 136 g/t Ag,0.4% Cu, 0.6% Pb, and 0.1% Zn (1,101 g/t AgEq) over 1.0m, and other deeper intersection of 2.77 g/t Au, 25 g/t Ag, 0.2% Cu, 0.2% Pb, and 0.6% Zn over 9.2m, including 19.95 g/t Au, 227 g/t Ag, 1% Cu, 1.3% Pb, and 4.7% Zn (2,507 g/t AgEq) over 0.20m; and hole PLI17-32 with 1.37 g/t Au, 68 g/t Ag, 0.1% Cu, 0.4% Pb, and 0.1% Zn (245 g/t AgEq) over 10.6m. “The underground drilling program is targeting high-grade Ag-Au epithermal mineralization and bulk tonnage-style polymetallic mineralization in the Plomosas Mine Area, with the objective to delineate high margin precious and base metals mineralization for planned resource estimation”.
- Newmont Corporation reported 2020 mineral reserves and resources for its Peñasquito and Noche Buena mines. Figures are shown in the tables below:

Rich-Mn jasperoid
By Miguel A Heredia
During the forty one week of the year (October 5th to October 11th, 2020), at least 27 press releases were announced by companies working in Mexico and 10 news published by the media, with seven informing on exploration results, seven announcing financial rounds, seven commenting on Mexican issues, six disclosing deals and corporate issues, six communicating production and financial results, three discussing social issues, and one reporting on resources and development of their mine operations ON MEXICO ISSUES, The Mining Chamber of Mexico (CAMIMEX) and other organizations in the mining sector urged the federal government to maintain the operations of the Mining Fund, which has counted, until now, with an amount of MXP $22,000M (about $1B). The fate of the Fund for the Development of Mining Production Zones (Mining Fund), which had drastically changed its distribution in the last two years, is now more uncertain. Alvaro Burgos Barrera, the State Secretary of Economic Development of Guerrero, stated that Mining fund distributed MXP $300M for urban infrastructure in seven municipalities of the state, but now this support won´t arrive anymore at the entity after the disappearance of such program, at the initiative of the current federal government. Mining companies operating in Mexico demanded to guarantee the resources of the Mining Fund to the mining communities. The mining sector of Zimapan, Hidalgo spoke against the extinction of the Mining Fund. Mexico loses shine to attract mining investment. President Andrés Manuel López Obrador plans to take a decision on how to manage Mexico’s lithium resources soon. ON EXPLORATION, In Sonora, Riverside reported assay results from 55 channel samples and 181 soil samples taken at its Cuarentas property and announced it is preparing a drill program.

Industrias Peñoles SAB de CV faces firmly the new challenges posed by the pandemic.
ON MEXICO ISSUES
- The Mining Chamber of Mexico (CAMIMEX) and other organizations in the sector urged the federal government to maintain the operations of the Mining Fund, which has counted, until now, with an amount of MXP $22,000M (about $1.04B), with an impact on 690 communities. The Mining Fund was created with the objective of benefiting the populations where the resources were generated.
- The fate of the Fund for the Development of Mining Production Zones (Mining Fund), which had drastically changed its distribution in the last two years, is now more uncertain. The resources collected between 2014 and 2018 have been used for the installation and maintenance of public lighting, sanitary landfills, water treatment plants, drainage works. Public jets and environmental projects such as reforestation, etc. In 2019, it was decreed that these resources be distributed in a general way in the country through the Ministry of Public Education (SEP), which reduces the possibility of continuing with the development of mining communities. It goes against the principles by which it was generated: to distribute the Mining Fund among mining states and municipalities to promote high-impact infrastructure works.
- Alvaro Burgos Barrera, the State Secretary of Economic Development of Guerrero, stated that Mining fund distributed MXP $300M for urban infrastructure in seven municipalities, but now this support won´t arrive anymore at the entity after the disappearance of such program, at the initiative of the current federal government.
- Mining companies operating in Mexico demanded to guarantee the resources of the Mining Fund to the mining communities claiming that is was created with the spirit of benefiting the populations where the resources are generated. The Mexican Mining Chamber (CAMIMEX) asked the federal government to guarantee the application of resources from the Fund for the Development of Mining Production Zones for the benefit of the more than 690 mining communities in the country located in 212 municipalities in 24 states of the Mexican Republic. That is the commitment 27 made by President Andrés Manuel López Obrador during his protest, which states: “The tax charged to companies for the extraction of the mineral will be transferred to the mining communities.”
- The mining sector of Zimapan, Hidalgo spoke against the extinction of the Mining Fund. The federal initiative to disappear 109 trusts with an economic sum of almost MXP $68.5 would cause Hidalgo to stop receiving part of those funds, in different lines, including the one focused on Science and Technology as well as the extractive mineral industry. One of the first impacts would be the cancellation of economic resources for the urban infrastructure of the municipality.
- Mexico loses shine to attract mining investment. After disagreements between the federal government and the mining industry, last year Mexico fell nine places in investment attractiveness for the mining industry, going from 29th place in 2018 to 38th in 2019. The federal government has been clear that no mining concessions will be granted during this administration. President Andrés Manuel López Obrador has declared that 40 percent of the national territory was concessioned and it is about stopping them “because with what has been granted, it is enough for millions of years.” Karen Flores, general director of the Mining Chamber of Mexico (CAMIMEX), refuted this statement and points out that 24 thousand 66 mining concession titles are in force in Mexico, representing 16.83 million hectares, equivalent to 8.59 percent of the national territory, for which is a myth to affirm that practically the entire national territory is concessioned to mining. At least 84 projects were postponed in 2019 due to different factors that affect their competitiveness, such as the price of metals, a higher tax burden, delays or rejections of permits, and uncertainty regarding possible changes in existing regulations, as well as in mining public policies, according to CAMIMEX.
- President Andrés Manuel López Obrador plans to take a decision on how to manage Mexico’s lithium resources soon. As is known, the government considers nationalizing the metal for batteries, whose demand is expected to increase in the coming decades to meet the growing manufacture of electric vehicles. What will be analyzed is to see if the country will opt for a total nationalization or to count with stricter controls on concessions, since all minerals belong to the State under Mexican law. While Mexico is not yet a lithium-producing country, this is expected to change in 2023 when project production begins in Sonora. Sonora is home to one of the largest lithium deposits in the world.
ON EXPLORATION
- Riverside Resources Inc., reported assay results from 55 channel samples and 181 soil samples taken at its Cuarentas property in Sonora and announced it is preparing a drill program to test some outlined targets.

- Brigadier Gold Limited, reported exploration results from the El Placer vein system within its Picachos project in Sinaloa. This vein system has been traced now for at least 4km along strike and comprises multiple parallel veins over a trend width ranging from 60 to 160 metres. Sample assay highlights include 7.4 g/t Au over 3.2m; 12.8 g/t Au, 54 g/t Ag, 0.1% Cu, 7.7% Pb, and 6.73% Zn over 0.5m; and 101 g/t Ag, 0.3% Cu, 2% Pb, and 11.6% Zn over 1m.
- Prismo Metals Inc., received environmental permit from SEMARNAT for its Palos Verdes project in Sinaloa. “The Palos Verdes drilling program will consist of about five holes, with the longest hole planned at 150-175m, designed to test the vein on strike and below the high-grade intercepts from a previous drill program carried out in May 2018. The best intercept from that program was 8.42 g/t Au and 2,336 g/t Ag, over an estimated 0.8m true width”.
- Vizsla Resources Corp., reported results from its current drill program at its Panuco property in Sinaloa. Significant drill intersects were encountered at hole NP-20-25 with 2.02 g/t Au, 255 g/t Ag, 0.3% Pb, and 0.6% Zn (449 g/t AgEq) over a true width (TW) of 15.3m; and hole NP-20-27 with 8.7 g/t Au, 870 g/t Ag, 0.8% Pb, and 2% Zn (1,696 g/t AgEq) over a TW of 2.58m.
- Advance Gold Corp., reported drill results from two holes collared at its Tabasquena project in Zacatecas, to test a 3,500m long continuous high chargeability Induced Polarization (IP) anomaly. Hole AGT-15 intercepted 122 g/t over a narrow interval of 0.33m, 198 g/t Ag over 2.23m, and 664 g/t Ag over 2.15m; and hole AGT-16 intercepted 0.7% Pb and 2.6% Zn over 6.5m, including 2.27% Pb and 5.45% Zn over 1.3m. A new geophysical survey will be underway within days to determine east to west dimensions of the geophysical anomaly at the northern end.
- VanGold Mining Corp., released assays from channel sampling carried out at its Pinguico property in Guanajuato. “El Pinguico vein system between the 4th and 6th levels (from approximately 130m to 185m below surface), covering an area approximately 55 meters in height, by 60 meters in width and where the stopped out area, plus remaining vein material, ranges from 1.5 meters to 5.5 meters wide. This exposure is adjacent to the El Pinguico shaft where crews continue to remove material blocking access to the #7 adit level”. Significant assays are 1.72 g/t Au and 630 g/t Ag (9.59 g/t AuEq or 767 g/t AgEq) over 1.6m; 4 g/t Au and 404 g/t Ag (9.05 g/t AuEq or 724 g/t AgEq) over 1.3m; and 4.59 g/t Au and 4566 g/t Ag (10.41 g/t AuEq or 833 g/t AgEq) over 1.2m.
