  • Napoleon Gomez Urrutia, mining leader and senator of the MORENA party, declared that is ready to go over the mining companies that do not pay enough taxes, pollute the environment and have too ground in mineral concessions. The mining leader is reviewing mineral concessions and said that mining companies should contribute to the government with more revenues. He also said that the Mining Law of Mexico has to be regulated in accordance with the interests of the country. “We are looking at the cancellation terms for a concession and its extension, because 50, 100 years is too long,” he explained.

  • The president of the Commission on Mining and Regional Development, Geovanna del Carmen Bañuelos de la Torre, said that it is necessary to create a new legal framework to standardize the safety, health and protect workers and the environment. She also recognized that the actual distribution of the Mining Fund lacks rigor on its application, and that a reform proposal has been formulated.


  • Sable Resources Ltd. summarized its 2018 exploration program, including information from its projects in Mexico. During 2018’s second quarter Sable completed 2,420 m in 12 drill holes at the Margarita project in Chihuahua, testing epithermal veins in Eocene-Oligocene volcanic rocks. “The project is defined by 5 veins; Margarita, El Caido, Juliana, Faviana, and Marie. All exploration drilling by Sable up to this point was executed along 750 m strike of the Margarita Vein”. Results for the first round of drilling include close to surface high-grade intersections like: 252 g/t AgEq over 11.3 m;  462 g/t AgEq over 4.25 m and larger low-grade halos as: 36 g/t AgEq over 21.35 m and 50 g/t AgEq over 44 m. “A second round of drilling planned to start in mid-January includes 1360m in 9 holes to extend the drilling for 1.5km along the known surface trace of the Margarita vein and to close the drilling grid to approximately 250m space. In addition, 1750m will be drilled in 13 exploration holes that will test the other veins”. Sable received title for 12 mining concessions covering 38,396 ha in Chihuahua, all covering stream sediment and rock sample anomalous areas, including the drill ready Vinata vein system located NE of the Margarita project. The company also holds projects in Canada, Peru and Argentina.

The work done confirmed a multi-stage system with an alteration foot-print at least 2.5 Km x 1.2 Km and that the best Cu mineralization is surface and drill core samples is in rocks with potassic alteration and a quartz-chalcopyrite-pyrite stockwork. There are indications that copper mineralization might be preserved at depth within the shallower part of the porphyry system(s). Future work is expected to include magnetic and ZTEM surveys in advance of possible drilling at the project.
  • Kottenay Silver Inc. reported that new assay results from outcropping quartz veins support the potential for the discovery of a high-grade silver deposit at its Columba project in Chihuahua.

Recoveries at the Santa Eulalia plant have been 89% Zn, 86% Pb. All the ore mined was from an area outside of the JORC defined resource.
  • Great Panther Silver Ltd. reported fourth quarter and 2018 production results for its properties in Mexico. During the year the company produced 1.86 M Oz Ag, 20,161 Oz Au, 1,958 tonnes Pb, 2,361 tonnes Zn from the two operations. At Topia, Durango, 18.9 K tonnes @ 326 gpt Ag, 0.83 gpt Au were processed during the quarter, recovering 92.9% Ag, and 53.4% Au to produce 183.7 K Oz Ag, 267 Oz Au, 474 tonnes Pb, 661 tonnes Zn. At the Guanajuato mine Complex 70.4 K tonnes @ 129 gpt Ag, 2.01 gpt Au were processed, recovering 87.2% Ag, 84.4% Au to produce 254.4 K Oz Ag, 3,833 Oz Au. Reflecting low metal prices, operations at the Guanajuato Mine Complex is shifting all production to the San Ignacio mine for 2019.
  • United States Antimony Corp. reported the status of beneficiation of ore at Los Juarez, Queretaro, where 30 K tonnes have been mined. The crusher and flotation circuits at the Puerto Blanco mill (in Guanajuato) are ready for production, while the tailings installation is nearly complete. Most of the cyanide leach plant has been built and is being installed. The caustic leach plant at Madero to process the flotation concentrates is operational and has recovered the precious metals with close to a 100% recovery, and pilot production of Au, Ag and Sb is about to start in Q1 2019.
  • Sierra Metals Inc. informed it is on track on its staged mine production increase from 3,000 to 3,600 tonnes per day (TPD) in Q1 2019 (and 5,000 TPD by 2020) at its Bolivar mine in Chihuahua. “Completion of the expansion included the installation of a refurbished mill, an electrical substation with 1250 KVA of capacity, a secondary crusher and a hydrocyclone cluster that allows for finer grind size optionality that is estimated to provide a 6% increase in copper recoveries from 80% to 86% at Bolivar Mine”.

Endeavour Silver Corp. reported consolidated production of 5.5 MOz Ag, 52,967 Oz Au (9.5 MOz AgEq) in the fourth quarter 2018.  Drilliing at Bolañitos returned multiple high-grade intersections, including 1.1 m (TW) @ 1,415 gpt Ag, 2.25 gpt Au in the San Miguel mine. Parral drilling and underground sampling returned  multiple high.grade intersections, including 4.2 m (TW) @ 934 gpt Ag, 0.21 gpt Au, 3.0% Pb, 5.9% Zn. El Compas commissioning has been delayed by metallurgical and plant issues that have been or are in the process of being corrected, while the mine development has been completed and and a 10K tonnes stockpile produced. At Guanaceví, the Milache and SCS orebodies development commenced. At Bolañitos, drilling outlined several mineralized areas and extensions to known areas, with potential to extend the mine life. At El Cubo, drilling of new targets failed to intersect any economic mineralization, and production is to be halved to increase mine life while more reserves are sought.

  • New Gold Inc. presented fourth quarter results, including figures from the Cerro San Pedro property in San Luis Potosi.  Mine closure activities continued at the Cerro San Pedro mine, and 1,448 Oz Au were recover by residual leaching of heap pads.
  • Torex Gold Resources Inc. announced 354 K Oz Au were produced at its El Limon-Guajes mine in Guerrero.
  • Capstone Mining Corp. released preliminary fourth quarter production results for 2018, including figures from its operations in Mexico.

  • Silver One Resources Inc. closed its previously announced private placement financing for gross proceeds of C$623.7 K. Silver One also commented it is not aware of any information other than that previously disclosed in its public filings, news releases or statements, which would result in the levels of trading activity and change in the share price recorded in recent days (Peñasco Quemado, Sonora; La Frazada, Nayarit).
  • Gainey Capital Corp. received conditional approval by the TSX Venture Exchange to close the first tranche of its non-brokered private placement of up to $1.15 M announced on November 28, 2018. In this tranche the closing accrued gross proceeds of $750 K (El Colomo, Nayarit).

  • Oceanus Resources Corp. informed that during 2018 carried a regional prospecting and mapping program on its El Tigre property in Sonora. The objective was to know the extent of El Tigre Formation, the rock package that hosts the historic El Tigre mine. Such formation was found to extend 5 km to the south reaching the Lluvia de Oro prospect, and 3 km further to the south at La Mancha workings. Prospecting and mapping was carried out also to the east, where several historical underground workings were located. Given the positive results, Oceanus applied for an additional 4,465 hectares, increasing its land position to 26,307 hectares. The company will continue prospecting, mapping and sampling during 2019 to establish drill targets.
