ON MEXICO ISSUES

  • Fortuna Silver Mines Inc., announced that it is trying to avoid the closure of its San Jose silver mine in Oaxaca after the expiration of its environmental permit last month. Although the San Jose mine has been in operation since 2011, its main environmental authorization expired on October 23, despite the company’s efforts since May to request an extension of the permit. A recent court order allows the mine to continue operating, but only temporarily. Maria Luisa Albores, the Environment Secretariat issued a statement saying it would work to organize a consultation with indigenous communities close to the project as part of the environmental authorization. It did not provide details on the timing of the consultation, nor did it say whether the mine could continue to operate in the meantime. The company stated that it is fighting for the stability of 1,200 active workers of its San Jose mine.
  • Mexico’s Secretary of the Environment and Natural Resources (SEMARNAT) announced that it will carry out an indigenous consultation to define the future of the San Jose mine in Oaxaca. A dozen of Zapotecas communities will decide whether the San José mine, owned by Minera Cuzcatlán, will continue operating in the Valles Centrales region of Oaxaca, through a consultation carried out by the Ministry of SEMARNAT. It should be noted that the San José mine has four environmental impact authorizations in force, however there is another one that expired on October 23, and although the company requested its extension in due time and form, SEMARNAT has not issued a ruling.
  • Fortuna Silver Mines Inc., provided an update on the appeal to the denial of the extension of the environmental impact authorization (EIA) at its San Jose mine, Oaxaca. “The appeal will be brought by Minera Cuzcatlán in the Mexican court. The grounds for the appeal are that Minera Cuzcatlán is in full compliance with all material environmental laws, and therefore Minera Cuzcatlán has the right to an extension of the EIA under applicable law”.

  • The National Autonomous University of Mexico (UNAM) and the Mexican Mining Chamber (CAMIMEX) signed a collaboration agreement to promote research, scientific-technical advice and the training of human resources related to the mining sector. The agreement will allow addressing specific problems in this strategic sector for the country, such as the management of polluting waste and the new technologies applicable in mining processes to reduce the environmental impact and the impact on local communities.
  • Mining companies in Mexico increased their consumption of clean energy from 14 to 31% from 2019 to 2020, according to the Mining Chamber of Mexico (CAMIMEX). The results correspond to the member companies of CAMIMEX, which account for about 90% of the value of the country´s mining-metallurgical production.
  • Silver production in Mexico was led by the companies Fresnillo plc, Newmont and Grupo México in 2020, reported the Mexican Mining Chamber (CAMIMEX). Silver mining production was 180.2 M Oz in 2020, 4% less than the corresponding year. Of that total, Fresnillo plc, the world’s largest producer company, recorded a production of 27.7%. This was followed by Newmont (15.4%) and Grupo México (8.8%). By federal entity, Zacatecas retains the first position, with a participation of 38.9%.The largest silver mines in the country are located in this state: “Peñasquito”, “Saucito” and “Fresnillo”.
  • The Mexican Geological Service (SGM) has detected 14 points to explore for lithium carbonate in Sonora. Lithium is used to create batteries, technological tools, mobile devices and electric cars that is revolutionizing the automotive industry.
  • The head of CAMIMEX, Fernando Alanis, stated that Mexican mining companies face “major delays” with environmental and water permits. “According to CAMIMEX, 18 specific mining project permits are pending before SEMARNAT, corresponding to projects that represent investment of nearly USD $2,800M. The metals sector seeks to boost operations in the one of the country’s biggest industries.

ON EXPLORATION

  • Benjamin Hill Mining Corp., released assay results from its Benjamin Hill property in Sonora with values as high as up to 20.0 g/t of Au at the eastern part of the area and values that ascend to 6.1, 4.4 and 3.6 g/t of Au to the south and silver values that exceed 200 g/t. These results confirm a N-S mineralized trend that runs at least by 3m long and 3 km wide. The company considers it is a new target area worthy to be drill tested.
  • Colibri Resource Corporation completed an IP survey and applied for a drill permit on its Evelyn project. At Evelyn property, the company completed an IP survey and reported that at 100m vertical depth, two broad areas of higher chargeability were identified underlying the northeast and central-east regions of the property; at 100m vertical depth, a sharp north-northwest showing more resistive domain to the northeast and a less resistive domain to the southwest was identified and has been interpreted as a moderately westerly dipping fault zone; and at 200m vertical depth, a strong chargeability was identified underlying the chargeability anomaly at 100m depth being interpreted as due to a stronger chargeability response below the zone of oxidation. Colibri also informed that it filed a drill permit with the Mexican Environmental Authority (SEMARNAT) to drill up to 56 holes at Evelyn property. This drilling program is based on data compilation and interpretation including the IP survey.
  • Colibri Resource Corporation, along with its partner Silver Spruce Resources Inc., informed on exploration results at their Mezquite, Jacky and Diamante properties.

These 10 holes are part of the 20 holes completed on July from eight pads for a total of 2,485m. Results of the remaining 10 holes are pending. The company also received a comprehensive interpretation of regional ASTER and LANDSAT 8 Hyperspectral and Image Analysis at their Jackie, El Diamante, and Mezquite properties.

ON EXPLORATION

  • Benjamin Hill Mining Corp (BHM), confirmed the presence of gold and copper mineralization at depth from channel samples collected underground in the Guadalupe and Cascabel adits at its Sonora Gold project. Highlights of the underground  samples collected over 2m intervals in the Guadalupe adit include 9.6 g/t Au and 0.5% Cu; 8.4 g/t Au and 0.3% Cu; 0.4 g/t Au and 4.3% Cu; 0.3 g/t Au and 3.5% Cu; and 0.2 g/t Au and 2.1% Cu. Highlights of the underground  samples collected over 1.5m interval in the Cascabel adit include 7.7 g/t Au and 0.4% Cu; 2.2 g/t Au and 0.4% Cu; 2.2 g/t Au and 0.7% Cu; 1.5 g/t Au and 2.9% Cu ; 1.3 g/t Au and 2.5% Cu; and 0.8 g/t Au and 2.4% Cu.

BHM geologists have previously mapped copper-gold mineralized structures over 8km cumulative length often attaining widths of 10´s of meters. The results of the adits sampling work supports the rational that the mineralized structures are drill ready targets”.
