  • 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.

Esperanza Silver will be delivering the Environmental Impact Statement (MIA) report and the study to propose the change of land use in forest land to the Secretary of the Environment and Natural Resources of the federal government (SEMARNAT) by the end of this year. Currently, the Esperanza Project is in the evaluation stage of the technical studies carried out during 2021 in terms of water and geotechnics. This year will be dedicated to the design of the technical project that will allow establishing the model of the mine’s industrial plant. At this point, both the company and the community will submit the request for an Environmental Manifesto to SEMARNAT, which could occur in mid-2023.

ON MEXICO ISSUE

  • Mexico Chamber of Deputies approved the initiative proposed by Andres Manuel López Obrador to reform the mining law on the nationalization of lithium, with 275 votes in favor, 24 against and 187 abstentions. The reform contemplates the authorization of mining concessions with the exception of lithium, which will be administered directly by the Mexican State. López Obrador reiterated that his government will not allow foreigners to exploit lithium even if they have previous concessions. Instead, there will be a State company “to exploit, explore, extract, process, industrialize and sell it”.
  • Fernando Alanís, Pro Secretary of the Confederation of the Industrial Chamber (CONCAMIN), declared that the project to reform the Mining Law to reserve the new concessions for the exploitation of lithium to the State is ambiguous and will add even more uncertainty and concern to investors. Despite the fact that Mexico is among the 10 largest producers worldwide of 17 minerals, being the first in silver and the eighth in gold, the mining industry has lost attractiveness for investment in recent years after the government suspension of mineral concessions, in addition to the high taxes paid by the sector in our country.
  • Armando Ortega, president of the Mining Task Force, of the Canadian Chamber of Commerce (CanCham) in Mexico, stated that the proposed reform of the Mining Law on lithium would violate Mexico’s commitments in international treaties. He argued that minerals cannot be reserved, in this case, for the exclusive exploration and exploitation by the State, without having made the aforementioned reservation in the Treaty between Mexico, the United States and Canada (T-MEC). From his point of view, reservations are areas of exclusion of obligations and commitments, and to do so without prior negotiation is arbitrary and prohibited. The CanCham argued that reserving lithium only for the exploration and exploitation of the Mexican State ex-post is in violation of both the provisions of the World Trade Organization (WTO), as well as those corresponding to all Free Trade Agreements (FTA). ) signed by Mexico.

ON EXPLORATION

  • Silver Spruce Resources Inc., filed environmental permits with the Secretariat of Natural Resources and Environment (SEMARNAT) to drill at their the Diamante, Mezquite and Jackie projects in Sonora. Approvals from SEMARNAT are expected to be obtained by late March, 2022.
  • Canasil Resources Inc., provided a review of the results from its 2020-21 drill program on the Candy Vein at its Nora project. 13 drill holes were completed for a total of 3,296m to test the Candy vein over a strike distance of 500m and to a vertical depth of 250m below surface. All the holes encountered the mineralized vein with the highest true width x grade value on hole NRE-21-11 with 5.31 g/t Au and 336 g/t Ag (748 g/t AgEq) over a true width (TW) of 11.29m, giving a TW x grade value of 8,445 g/t AgEq x m. The drill results show that the Candy vein hosts consistently high grade gold and silver mineralization over appreciable widths. The Candy vein is known over 3km long but only 500m have been drill tested. Additionally, Canasil reported that systematic grid soil sampling over a 2km east-west and 3km north-south area covering the central zone of the project returned widespread silver, gold, copper, zinc and lead geochemical anomalies. “The gold and silver anomalies are particularly strong over the 3-Km strike extent of the Candy vein structure on the western side of the project area, as well as to the southwest and east of the Candy vein structure. A strong silver and gold anomaly also extends for 1.5 Km southwest from the location of the above high grade drill intercepts on the Candy vein and a breccia target has been identified to the south with potential for hosting bulk tonnage disseminated silver-gold mineralization”.

Highlighted core length intervals comprise 16.5 m @ 0.27 gpt Au, 5 gpt Ag; 22.5 m @ 0.22 gpt Au, 3 gpt Ag; 18.0 m @ 1.21 gpt Au, 1 gpt Ag; 22.5 m @ 0.57 gpt Au, 1 gpt Ag; 13.5 m @ 0.30 gpt Au, 6 gpt Ag; 7.5 m @ 0.22 gpt Au, 1 gpt Ag. “In all holes the mineralization appears to be controlled by irregular sulphide enriched fractures-veinlets with minor quartz and/or alteration clay minerals typical to High Sulphidation mineral systems”.
  • Sierra Madre Gold and Silver Ltd. announced that a second drill rig has been mobilized to its Tepic project in Nayarit. “This second rig is smaller and more portable than the first while maintaining the depth capacity and large core diameter that the Company requires. The decision to mobilize a second rig is a result of the success of the trenching program which has identified several additional drill targets and the superior assay turnaround time at the current laboratory”.

  • Vizsla Silver Corp. retracted the maiden resource estimate released on Feb 28, 2022 (see above) on its Panuco project in Sinaloa. “An internal review of the estimate identified a miscalculation made by an independent consultant in the conversion of lead and zinc grades into the silver equivalent calculation. This in-turn lifted lower grade zones above the economic cut-off, adding tonnes to the resource but lowering the overall grade”. The next restatement corrects this. Indicated mineral resources are estimated at 5.0 M tonnes @ 191 gpt Ag, 2.08 gpt Au, 0.26% Pb, 0.50% Zn, containing 30.5 M Oz Ag, 331.1 K Oz Au, 13 K tonnes Pb, 24.6 K tonnes Zn.
