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.

  • 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).

  • 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 MEXICO ISSUES

  • CAMIMEX (Cámara Minera de México), in a response to El Financiero, expressed that any modification to the mining regulations has to take into account the wellbeing of the communities and its environment. The organization, of which leading companies like Peñoles, Grupo México and Minera Frisco are members, considers mining is one of the most supervised sectors in the country, with a modern and robust regulatory frame, following international standards, although areas of opportunity can always be identified.  “We have approached diverse authorities on the public administration and found openness to solve any pending issues and consolidate the international competitivity that benefits the country development”.

ON EXPLORATION

  • Orex Minerals Inc. contracted Geotech Ltd. To perform a VTEM (Versatile Time Domain Electromagnetic) airborne survey over its San Luis del Cordero project in Durango. Old mine workings and mineralized showings wrap around a Tertiary quartz-feldspar-porphyry intrusive. The helicopter-borne survey, with accompanying horizontal gradiometer and radiometric surveys, is to identify discrete conductive anomalies, as well as mapping lateral and vertical variations in resistivity. The airborne survey will be conducted over a grid at 100 m line-spacing for approximately 275 line-km, with measurements every 2-3 m along survey lines.
  • Prospero Silver Corp. has started phase 2 drilling at its Pachuca Se project in Hidalgo. Fortuna Silver Mines Inc. has an option to acquire up to a 70% interest in the 6,699 hectares project (24 km SE from Pachuca) by spending a total of US$8 M and completing a preliminary economic assessment (PEA), spending more than US$1 M in the first year. A six-hole, 4,200 m program started to test a number of potential drill targets. In a Fortuna funded program in early 2018, 1,800 m of drilling tested three distinct targets, intercepting what is interpreted to be the upper parts of a mineralized epithermal system.
  • Radius Gold Inc. staked a 9,600 ha property called the Rambler project, in Chihuahua, some 20 km NW from Radius’s Amalia project.
