 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.
  • Azure Minerals Limited, released drilling results from its Alacran project in Sonora, where its JV partner Minera Teck completed 21 holes phase 2 diamond drilling campaign for 10, 540m. 16 of the drill holes targeted porphyry-style copper mineralization at Cerro Alacrán prospect, while the remaining 5 holes targeted epithermal-style precious metal mineralization at Cerro San Simon and Cerro Colorado areas. This phase of drilling confirmed the existence of porphyry copper mineralization with broad zones of visible chalcopyrite intersected. Significant drill intersections include hole ALA-18-001 with 0.17% Cu over 118m; hole ALA18-003 with 0.25% over 131.7m; hole ALA-18-011 with 0.19% Cu over 137m; and hole ALA-18-014 with 0.21% over 177.3m.

This hole intersected 54.47 g/t Au over 16.5m, and is located in the North Hill Zone; a series of 9 consecutive assays including an intersection of 80.3 g/t Au, interpreted to correspond with hole Q-8b. This hole intersected 9.64 g/t Au over 13.5m; and another series of 6 consecutive assays including 0.54 g/t Au, 8.52 g/t Au, 20.66 g/t Au, 16.23 g/t Au, and 6.97 g/t Au, interpreted to correspond with hole P-9b located in the Main Zone, which encountered 10.16 g/t Au over 9m.
  • Silver Spruce Resources inc., completed field work at its Pino de Plata project in Chihuahua. The field program expanded areas of intrusive-related alteration and mineralization to > 50 hectares; confirmed that high silver grades are present on surface at El Terrero and Gossan areas; added three new vein targets at La Perla, Santa Clara and El Muro vein systems; and refined drill collar locations and orientations to optimize targeting. The company announced that eight targets were identified for drill testing: “gossans in the Gossan zone, skarn/replacements at Santa Elena, the Terrero mine target, the La Perla vein and associated alteration zone, the Santa Clara vein, the Theodora vein, the Sierpe veins and associated alteration, and the newly defined Muro vein.” The company holds a drill permit for 30 holes but only plans to drill 12 holes for an estimated of 2,000m during the phase 1.
  • Radius Gold Inc., provided an update of its ongoing drilling program at its Amelia project in Chihuahua. Radius has completed three drill holes proximal to hole AMDD19-010 which encountered 12.38 g/t Au and 309 g/t Ag over 34m of true width. Hole AMDD19-011 intersected 97m of “varying intensity quartz veins, stockwork veining and diorite dykes”; hole AMDD19-012 intersected a zone of 53m of “alteration including variable stockworks, silicification and hydrothermal breccias”; and hole AMDD19-013 intersected 17m of “moderate to strong silicification, tectonic breccia with micro vein stockworks and traces of fine sulphides”. Assays for these holes are pending.

The Mining and Exploration News in Mexico: Highlights on the First Week of May, 2019

By Jorge Cirett

During the 18th week of the year (April 29th to May 5th, 2019), at least 35 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, Newmont Goldcorp Corp. informed on the intention to temporarily suspend operations at the Peñasquito mine in Zacatecas, due to an illegal blockade lasting for more than a month now. More than 300 mine employees protested outside the Zacatecas Congress, accusing José Narro, senator by Morena (the president’s party) of instigating the blockade. Drill core from La Xora project in Nayarit was added to The Mexican Core Shack. ON EXPLORATION, Nine companies presented advances in the exploration of their properties: In Baja, One World Lithium has received the permits to drill its Salar Del Diablo property. In Sonora, Sonoro Metals disclosed assays for the first 15 RC holes of the second drilling campaign; Ridgestone updated the work done to date at Rebeico; Minaurum staked a large chunk of ground at its Alamos project. In Chihuahua, Silver Spruce released surface sample results from its Pino de Plata project; Radius Gold released exciting results from the first hole of the second drilling campaign at Amalia; Kootenay Silver has initiated drill road construction for its incoming campaign at Columba. In Jalisco, GoGold released results from its drilling campaign at Los Ricos. In Zacatecas, Alien Gold updated on the exploration effort at its Donovan 2 property. ON MINING, nine companies presented its first quarter 2019 results, while one company presented its 2018 results. ON FINANCING, First Mining, and Prize Mining are to raise $6 M and $1.5 M respectively. Leagold Mining secured a 200 M term loan and a 200 M revolving credit. ON RESOURCES AND DEVELOPMENT, no relevant news.  ON DEALS AND CORPORATE ISSUES, Alio Gold received notice of a civil claim from a former Rye Patch shareholder.  

ON MEXICO ISSUES

  • Newmont Goldcorp Corp. informed on the intention to temporarily suspend operations at the Peñasquito mine in Zacatecas (one of the largest in Mexico, produced 272 K Oz Au in 2018), due to an illegal blockade by a trucking contractor and some members of the Cedros community that began on March 27, 2019. The company announced on April 9 that the trucking contracts will now be signed with independent truckers, to their economic benefit and to avoid the repeated extortion blockades by the current trucking contractor. Newmont Goldcorp denounced that the blockader’s public claims that focus in water quality and employment, turn in a direct petition for large amounts of money when done privately. The company asks for help from the Mexican and Zacatecan authorities to resolve the illegal blockade that affects the income of more than 20 thousand persons, directly or indirectly. On a different event, about 300 employees of Minera Peñasquito, protested outside the Zacatecas Congress against the illegal blockade that keeps paralyzed the Peñasquito mine. The protesters accused Jose Narro, senator by the president party, Morena, and his acolyte Felipe Pinedo of blackmailing the company with false water contamination statements.  
  • Core from La Xora project, in Nayarit, was added to the Mexican Core Shack (https://gambusinoprospector.com/mexican-core-shack/), under the epithermal low sulphidation section.

ON EXPLORATION

  • Sonoro Metals Corp.  reported assay results from the first 15 reverse circulation holes of the second phase drilling program at its Cerro Caliche property in Sonora. All holes encountered gold mineralization, which extend mineralization 1.25 Km NW from the Central Zone, where the first drill campaign defined a series of NW striking structures, outlining three shallow bulk tonnage oxidized mineralized zones in metasedimentary and volcanic rocks. Previously reported results come from the Central Zone prospects Japoneses, Abejas, El Colorado and Guadalupe, whereas the new drill holes tested El Rincon, Gloria, El Boludito, and Veta de Oro zones. Highlighted results comprise 10.67 m @ 2.73 gpt AuEq; 3.05 m @ 5.48 gpt AuEq; 10.67 m @ 0.74 gpt AuEq; 6.1 m @ 0.80 gpt AuEq; 15.24 m @ 1.05 gpt AuEq.
  • Alien Metals Ltd. updated on its exploration work at its Donovan 2 project in Zacatecas. Work to date supports indications of volcanogenic massive sulphide (VMS) mineralisation on multiple target areas open along strike, with surface assays of up to 3.3% Cu, 0.25% Zn. Currently there are magnetic, chargeabilty and resistivity anomalies, and a gravity survey underway is to refine the targets on this project, which is 24 kilometers from Teck’s San Nicolas deposit.
  • Ridgestone Mining Inc. announced that exploration work to date on its Rebeico property in Sonora defined the 1.2 km long Alaska vein and intensely altered breccia zones SW of the vein, carrying Cu, Au and Ag values, as well as bismuth anomalies. An 18 line-kilometer induced polarization (IP) survey identified a chargeability anomaly below the breccia zone. A 12 hole 1,430 m diamond drill program tested 500 m of the Alaska vein. Eight of the twelve holes intersected significant grades, including: 0.80 m @ 1.41% Cu, 2.95 gpt Au; 2.0 m @ 2.78% Cu, 8.69 gpt Au; 1.40 m @ 3.25 gpt Au; 1.50 m @ 1.39 gpt Au; 1.0 m @ 0.30% Cu, 5.61 gpt Au; 3.25 m @ 2.41% Cu, 8.31 gpt Au; 1.50 m @ 1.22% Cu, 36.10 gpt Au.  
  • One World Lithium Inc. has received the permit required to start its 12 hole, 4,250 m drilling program at its Salar del Diablo property in Baja California. The company intends to test three geophysical anomalies, a geochemical anomaly, and structures that may trap and concentrate brines. The Salar del Diablo Property has never been drilled in the past.
  • Silver Spruce Resources Inc. released surface sample results from its Pino de Plata property in Chihuahua. The samples returned 19 gpt Ag, 16 gpt Ag, 2 gpt Ag, 1,1,30 gpt Ag, 123 gpt Ag, 95 gpt Ag and 255 gpt Ag; up to 0.19 gpt Au, up to 802 ppm Cu, up to 3.7% Pb on samples 0.2 to 1.0 m in length. The two targets in the area comprise El Terrero and the Gossan area. At El Terrero, a 32 hectares zone “of multiple flat-lying brecciated zones hosted by a zone of strong argillic alteration” is the target, while at the Gossan area a series of hornfels and skarns developed near an intrusive contact may host massive sulphide replacement bodies associated to structures.
  • Radius Gold Inc. reported the first results from the second diamond drill campaign at its Amalia project in Chihuahua. The program is operated by Radius and funded by Pan American Silver Corp. under a JV agreement by Which Pan American can earn an initial 65% by making cash payments totaling US$1.5 M (of which US$100 K have been paid) and spending US$2 M on exploration over four years.

ON MEXICO ISSUES

  • Almaden Minerals Ltd. informed that “a lower court in Puebla State has ruled that Mexico’s mineral title system is unconstitutional because consultation is not required before the granting of mineral title………..This ruling can be appealed by both the Government of Mexico and Almaden. The Company believes that this lawsuit is part of a broad effort by special interest groups to change the mining law and there are other similar actions active across Mexico”. Almaden stated that no communities within the company’s current mining concessions on its Ixtaca project in Puebla are party to this lawsuit.
  • Fresnillo PLC. Presented its 2018 annual report. It is here recommended to all interested in the mining business in Mexico to take a look to the report (http://www.fresnilloplc.com/media/412015/fres-30452-annual-report-2018-web.pdf), especially on the section “Managing our risks”. In the said section, the risks of participating in the industry in Mexico are assessed, including those of metal prices, potential actions by the government, access to land, security, public perception against mining, safety, union relations, exploration, project performance, cyber security, environmental incidents and human resources. Although the report had in mind Fresnillo’s particular situation as one of the largest Mexican mining conglomerates, many parts of the evaluation concern risks that affect all mining enterprises in the country.

The Mining and Exploration News in Mexico: Highlights on the Third Week of March, 2019

By Jorge Cirett

During the 12th week of the year (March 18th to March 24th, 2019), at least 20 press releases were announced by companies working in Mexico.  ON MEXICO ISSUES, a worrisome statement from the Mexican president regarding the mining concessions makes evident the need to augment the interaction of the mining industry with all levels of government. ON EXPLORATION, in Sonora, Riverside Resources disclosed initial results from exploration work at its recently staked Sandy project; In Chihuahua, Sable released exciting drill results from its Margarita project; Kootenay presented results from surface sampling at its Mecatona property; Evrim and Harvest Gold released final drill results from Cerro Cascaron; Silver Spruce is defining shallow targets for an incoming drill program. In Durango, Gainey Resources indicated that the main vein system at its Las Margaritas project is over 3 Km long. In Veracruz, Azucar Minerals presented long and favorable results from one more hole at El Cobre.  ON MINING, Torex Gold paid US$11.9 M in taxes during 2018. Excellon reported financial results for Q4 and full year 2018. ON FINANCING, Sonoro Metals is to undertake a financing round to raise up to $650 K. First Majestic is to extend its share repurchase program. Solaris Copper closed a C$3.9 M placement. ON RESOURCES AND DEVELOPMENT, Almaden Minerals. Issued a Report on Corporate Social Responsibility for its Ixtaca project in Puebla, and submitted an environmental report for permitting. VVC Exploration updated its resource estimate for the Samalayuca project in Chihuahua. Gold Resource reported on a high-grade result from sampling a new crosscut during development at its El Aguila project in Oaxaca. ON DEALS AND CORPORATE ISSUES, Silver One hired Strata-Star Group for investor relations.

ON MEXICO ISSUES

  • On a worrisome statement for the Mexican mining industry, during one of his daily press conferences the president of Mexico, Andres Manuel Lopez Obrador, expressed that although no mining concession is to be revoked, no more mining concessions are to be granted. The only requisites are that mining companies, “specially the Canadian ones”, conduct a clean mining operation, that miners are well paid and that they pay the same tax rates than in Canada. He added that the concessions delivered by past governments in the last 36 years were about 40 to 50 M hectares, meaning 30% of the national territory “and they wouldn’t finish with it in a thousand years”.
  • Note from editor. In the view of this letter editor, the president words express a lack of knowledge about the rigid guidelines under which exploration and mining international companies, and Canadian ones in particular, obtain financing, explore, interact with the communities, develop, mine and reclaim the used land. On his other remarks, mining companies pay salaries above average in Mexico, and if Canadian companies followed the Mexican president words, they would be paying fewer taxes, not more. Mexico needs more land under mining concessions, not less, as these concessions, besides paying hefty duties,  are the basis for investments that feed a long chain of service providers that benefit hundreds of thousands of Mexicans. It is clear and evident that we, as part of the mining industry, need to invest the time and resources to educate the different levels of government about the benefits of mining.  

ON EXPLORATION

  • Gainey Resources Capital Corp. reported that mapping and sampling of its newly-optioned Las Margaritas project in Durango has extended the strike of the main vein system to 3.5 Km, collecting grab samples with assays of up to 73.7 gpt Au. The best mineralization is along a 1,750 m section where 15 of 25 samples assayed more than 1 gpt Au, and six of those more than 5 gpt Au. “Gold mineralization occurs within druzy quartz veins, veinlets and stockworks with up to 3% disseminated pyrite”, with variable widths of up to two metres.

The Mining and Exploration News in Mexico: Highlights on the First Week of March, 2019

By Jorge Cirett

During the 10th week of the year (March 4th to March 10th, 2019), at least 16 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, The cancellation of the Los Cardones project in Baja California Sur was announced by the president of Mexico. According to the Fraser Institute, Mexico climbed several positions on its ranking, although security and taxation remain dragging down its overall ranking. On PDAC’s Mexico Mining Day, the participation of Francisco Quiroga, Pedro Haces and the governors of Durango and Sinaloa left a bittersweet message, as an invitation for investment was mixed with the government impulse for community consultations, the reviewing of mining concessions, labor issues and environmental revisions.   ON EXPLORATION, In Sonora, Sonoro Metals commenced a second phase of RC drilling at its Cerro Caliche property. In Chihuahua, Radius Gold informed is working on a revised geological model of the previous drilling campaign as it prepares for the next at the Amalia project. In Durango and Veracruz. Chesapeake Gold is to focus its 2019 exploration program in properties near its flagship Metates project, and in the Tatatila project in Veracruz. ON MINING, Americas Silver, Avino Silver and Premier gold reported operating and/or financial results for the Q4 and full year 2018. ON FINANCING, Minera Alamos corrected a previous financing press release, Kootenay Silver increased the size of its placement to $7 M. McEwen Mining suspended distribution of its dividend. Mako Mining raised CAD$4.5 M. ON RESOURCES AND DEVELOPMENT, Mag Silver reported on 46,000 m of drilling and the discovery of a new vein trend at Juanicipio, in Zacatecas. ON DEALS AND CORPORATE ISSUES, Oroco informed on the status of legal actions regarding its intention to acquire the Santo Tomás project in Sinaloa. Alio Gold changed CEO and Great Panther Silver Ltd. changed its name to Great Panther Mining Ltd. as it diversifies into gold mining.

ON MEXICO ISSUES

  • The Durango and Sinaloa governors, Jose Rosas Aispuro and Quirino Ordaz, respectively, attended the PDAC convention in Toronto, looking to strengthen the ties with Canadian companies and promote investment in the local mining sector.
  • The president of Mexico, Andres Manuel Lopez Obrador, announced the cancellation of the Los Cardones open pit mining project in Baja California Sur (on the bright side, the cancellation could be the result of negotiations with the project owner, which has multiple government contracts in other industries. On the other hand, the president said he took the decision because he has the authority to do so).
  • The Fraser institute released its annual survey on mining jurisdictions of the World, Mexico climbed several positions to reach the 29th on the ranking, from the 44th on the previous year. Our Latin American competitors on the foreign investment race, Chile and Peru, also raised to the 6th (from the 8th) and 14th (from the 91th) position respectively. The categories on which Mexico can improve significantly are: “Disputed Land Claims” (58th position), “Socioeconomic Agreements/Community Development” (59th position), “Labor Regulations” (58th position), Security (80th position, regrettably) and “Taxation Regime” (71st position, just 13th places from the bottom). To download the report: https://www.fraserinstitute.org/sites/default/files/annual-survey-of-mining-companies-2018.pdf.
  • In PDAC, Francisco Quiroga, undersecretary of Mining on the Secretaría de Economía (Ministry of Economy) asked Canadian mining companies to accept public consultations to avoid harmful effects on society and the environment. He also solicited fiscal observance, environmental protection and human rights respect by the companies to avoid the closure of mines. He offered an administrative simplification to miners by the implementation of a sole attention desk to reduce paperwork.
  • Also in PDAC, and during the Mexico Mining Day, Pedro Haces Barba (Morena senator) stated that Canada is a strategic partner on the mining sector. He expressed the Congress and Senate support to stimulate the development of the industry, giving form to a legal framework in the leading edge, with the participation of experts, producers, environmentalists, workers and all other involved. Haces also stressed the compromise to impulse significant changes to the mining law to benefit from the sustainable exploitation of natural resources in pace with the regional dynamics and global challenges.  

ON EXPLORATION

  • Radius Gold Inc. informed on the review and re-logging of five holes drilled to test the Campamento structural corridor (now called San Pedro) at its Amalia project in Chihuahua.
