  • Canuc Resources Corporation provided an update on its exploration program at its San Javier project in Sonora. On the Silver Mountain Zone, the 63-sample grid covered the central part of a NE-SW trending magnetic high in the north part of the San Javier project area. Within the soil grid, samples ranging from 5,123 to 36,671 ppb Ag (5 to 36 g/t) define a 50 to 100 m wide trend that extends for approximately 300 m across the grid. Only 7 of the 63 samples collected contained less that 1 g/t Ag and. The Ag anomaly is accompanied by a modest Au anomaly having values ranging from 38.6 to 87.5 ppb within a relatively high 2.0 to 32.5 background. Only 9 samples contained less than 5.0 ppb Au. On the Gold Zone, the company excavated 3,295m of trenches ranging from 65m to 638m in width. From these trenches, 1,829 channel samples have been collected and additional 46 samples have been collected from various locations within the trend. Results have been reported only on the first 3 trenches which returned elevated gold and copper values. Sampling results are still pending for the rest of the trenches. On the Copper-Gold Stockwork Zone, a total of 22 samples were collected from 3 locations on the north flank of a donut shaped magnetic high in the north–central part of the property. Average grade of the sampling is 0.38% Cu, 0.29 g/t Au, and 3.9 g/t Ag. Canuc plans to cover with soil samples the southwest extension of the strong Ag anomaly referred as Silver Anomaly target; to carry out a detailed mapping on at least 40 know mineralized zones within the property, as well as along the 11 trenches excavated across the Gold Zone, and in the area of the Stockwork Copper-Gold Zone, to provide necessary information in advance of drilling.

The Mining and Exploration News in Mexico: Highlights on the Third Week of February, 2021

By Jorge Cirett

During the 7th week of the year (February 15th to February 21st, 2021), there were at least 42 press releases by companies working in Mexico. To note, nine companies posted exploration advances on their properties (with GoGold’s Casados discovery deemed the most significant), six presenting quarterly results, two informing on power cuts, six posting on financing or share options, nine on project development and two on corporate issues. ON MEXICO ISSUES, the Mexican mining sector is dealing with several (government induced) challenges and great opportunities. The Nuevo Leon State government intends to push its mining sector. Camimex points out the goal of the energy bill should be to promote the reduction of the electricity cost. ON EXPLORATION, in Sonora, Tarachi Gold released drilling results from the San Javier concession; Tocvan Ventures initiated the next exploration campaign at Pilar. In Chihuahua, Radius Gold released drilling results from the Amalia project; Silver Spruce is to carry a LidDar survey at Pino de Plata; Mammoth Resources released observations by independent consultants on its Tenoriba property. In Sinaloa, Prismo Metals presented drilling results on Palos Verdes; Vizsla Silver informed seven rigs are now churning at Panuco; Brigadier Gold released drilling results from its Picachos project. In Jalisco, Stroud Resources informed on the approval of its drilling permit for Santo Domingo, Hostotipaquillo. ON MINING, Starcore International, Pan American Silver, Golden Minerals, Hecla Mining, Newmont, and First Majestic released quarterly and full year 2020 reports. Excellon and Gatos Silver informed on work affected by the power cuts in the north of the country. ON FINANCING, SGold79 Mines and Vizsla Silver granted options to directors, officers and employees; Consolidated Zinc, Orogen Royalties, Van Gold Mining and Brigadier Gold informed on their financing rounds. Heliostar Metals qualified to trade on the OTCQX Best Market. ON RESOURCES AND DEVELOPMENT, Avino Silver will drill 12,000 m on the Avino property. Sonoro Gold released results from 24 holes at Cerro Caliche. VanGold released positive results from the PEA on El Cubo and El Pinguico in Zacatecas. McEwen Mining filed the FS on the Fenix project. GoGold Resources made a discovery at Los Ricos North. Coeur Mining released the 2020 resource estimate for Palmarejo. Capitan Mining released drilling results from the Peñoles project. Golden Tag released results from drilling at San Diego, Velardeña. GR Silver Mining reported drilling results from Plomosas.  ON DEALS AND CORPORATE ISSUES, Azure Minerals is divesting its Mexican portfolio. Premier Gold shareholders had to vote in February 19 on the arrangement with Equinox Gold. ON SOCIAL RESPONSIBILITY, Minera Media Luna is to make a large investment during the next three years at the Media Luna project in Guerrero, with a significant impact in the communities of the area.

ON MEXICO ISSUES

  • The Mexican Mining Sector is dealing with several challenges and great opportunities, according to mining companies executives. The outright denial to grant mining concessions, the lack of a medium term regulatory view, security issues, the blockage by SEMARNAT of several projects, the lack of clarity and rules and lagging paperwork have to be weighed against the great mineral potential of the country, and its qualified workforce.  
  • The Nuevo Leon State government seeks to foster the mining activity on the southern part of the state. Nuevo Leon has significant deposits of barite, clays, limestone, dolostone, gypsum, phosphorite and talc, among other minerals.
  • Camimex (Cámara Minera de México) pointed out that the goal of an energy bill should be to promote the reduction of the electricity cost, not to favor any given company. With the introduction of the auto supply figure a few years ago mining companies saw the electricity cost go down from US$0.12-$0.13 Kw/hr to US$0.065 Kw/hr, while those that rely on the government supplied electricity pay US$0.08 and $0.09 Kw/hr. Miners in Perú and Chile pay US$0.06 Kw/hr and those in USA and Canada US$0.04 Kw/hr and US$0.02 Kw/hr respectively.
  • Newmont’s Peñasquito mine in Zacatecas produced 520 K ounces of gold and 934 K gold equivalent ounces in 2020. Production for 2021 is estimated at 660 K ounces of gold and 1.12 M gold equivalent ounces.

  • Stroud Resources Ltd. informed the drill permit application has been approved for its Santo Domingo property in Hostotipaquillo, Jalisco. The first phase consists of 12 drill holes, and a second phase comprises 38 holes to expand the mineral resources. “Stroud’s exploration of the two main mineralized zones has drilled through many of the workings. These zones; La Rayas and Guadalupe, are a series of banded to breccia style epithermal quartz carbonate vein systems represented with miargyrite, galena, sphalerite, argentite and native silver and gold. La Rayas is 30 to 35 metres wide and Guadalupe is 15 to 30 metres wide. Both are parallel structures with greater than a 700-metre strike length and about 300 metre depth”.
  • Mammoth Resources Corp. released observations by independent consultants on its Tenoriba property in Chihuahua. According to them the mineralization in the area is of epithermal high sulfidation type and occurring near the angular unconformity between the Lower and Upper Volcanic Groups. A thorough 2-year exploration program was recommended to evaluate the main prospect areas and to address areas that have to date seen little or no work.
  • Tocvan Ventures Corp. announced the start of the next phase of exploration at El Pilar in Sonora. The planned work is to include mapping and sampling of key target areas across the project. The property is interpreted as a structurally controlled low-sulfidation epithermal system in andesitic and rhyolitic volcanic rocks.

ON MINING

  • Excellon Resources Inc. informed it is looking for alternative energy sources for its Platosa mine in Durango. The energy utilised by the company is generated with natural gas, and it has seen its price multiplied up to a hundred times due to the intense cold wave in Texas.
