During the 28th week of the year (July 8th to July 14th, 2019), at least 27 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, Camimex announced investments for US$2,705 M on new gold projects from 2019 to 2024. The same organism informed Mexico’s gold production declined 6.7% between 2017 and 2018. ON EXPLORATION, In Baja California, One World Lithium released results from drilling at Salar del Diablo. In Sonora, Magna Gold started its phase one exploration program at its Mercedes project on the Santa Rosa de Yecora district.

ON MINING, Torex Gold, Coeur Mining, Great Panther, GoGold Resources and Endeavour Silver presented production results for the second quarter of 2019. ON FINANCING, Mexican Gold Corp, Impact Silver, One World Lithium, Oceanus Resources, Silver One Resources, Advance Gold and Millrock undertook or completed tranches of financing rounds for a combined $13.45 M. Evrim Resources granted 1 M stock options to an officer. ON RESOURCES AND DEVELOPMENT, SilverCrest Metals filed the PEA on Las Chispas, Sonora. VVC Exploration received the environmental permit  and a land use change permit for its Samalayuca project in Chihuahua. SilverCrest Metals released high grade results from underground sampling of the Babicanora vein at Las Chispas, Sonora. Goldplay released good gold results from trenching on an extension of the Nava zone on its San Marcial project in Sinaloa. ON DEALS AND CORPORATE ISSUES, Orex Minerals and Pan American Silver entered into an agreement to negotiate a formal JV agreement on the Sandra Escobar project in Durango. Oroco Resources signed a letter of agreement to acquire the 766 ha. Rossy concession adjacent to Oroco’s land package on the Santo Tomas district in Sinaloa.


  • Camimex (Cámara Minera de México), informed on a list of new gold producing projects that involve the investment of US$2,705 M between 2019 and 2024. Among the biggest investments are those of Torex Gold (US$482 M) in Media Luna, Guerrero; Grupo Mexico’s (US$413 M) Buenavista Zinc in Sonora and Fresnillo’s (US$350 M) Orisyvo in Chihuahua. Other investments include the second dynamic leaching plant at La Herradura; the Pyrites plant in Fresnillo; Goldcorp’s Pyrite plant in Peñasquito, Zacatecas; and Endeavour’s El Compas in Zacatecas; Candelaria Mining is to start operations at Pinos, Zacatecas; Mag Silver and Fresnillo are to begin production at Juanicipio, Zacatecas; Telson Resources is to finish construction of the mine at Tahuehueto, Durango; Hecla’s will continue with open pit and then underground operations at San Sebastian, Durango.
  • Camimex stated that during 2018 Mexico’s gold production diminished 6.7% compared with 2017, reaching 3.8 M Oz Au. Five companies produced more than half of the overall gold production in 2018: Fresnillo (24.1%), Torex Gold (9.3%), Agnico Eagle (8.5%), Goldcorp (7.1%) and Minera Frisco (6.5%) (Editor’s note.- This last company has the dubious honor of being the most opaque for disclosing production, reserves and resources from its projects in Mexico).


  • Sable Resources Ltd. has received the permit needed to drill the Vinata project in Chihuahua. The surface agreements have been approved by the local community for an initial 2,500 m diamond drill program “to test the vertical continuity and mineral zoning along a section of the Vinata vein system where the veins are observed outcropping over 1000 m along strike”. Sable will contract a ground electromagnetic survey (CSAMT) to better define the vein system at depth and the contacts between a felsic dome and volcanic and sedimentary rocks. The mineralisation at Vinata occurs as a series of quartz veins that outcrop for 1,200 m, with multiple sub-parallel veins and stockwork zones over a width of 15 to 170 m, with individual veins ranging to up to 12 m in width.
  • One World Lithium Inc. released results from drilling at its Salar del Diablo property in Baja California (there is not a state named Baja California Norte in Mexico). The drill holes did not reach the target depths due to “the constant sluffing of sand, presence of multiple clay formations, unconsolidated gravel and rubble”. The highest lithum grade in sediment samples was 273 ppm Li, whereas the water samples are thought to have been diluted by the injection of significant amounts of fresh water while drilling. The Company intends to resume its 4,250 foot drilling program before the end of September 2019.
  • Discovery Metals Corp. has been granted drilling permits for its Monclova project in Coahuila. “The Real Viejo area is the key near-term target. It hosts five historic shallow underground mines along a strike of 1.5km at a limestone-intrusive rock contact”, with rock channel samples averaging 277 gpt Ag, 6.7% Zn, 1.9% Pb. The Real Viejo area is 2 square-km in size and is located along the southern contact of the Monclova intrusive complex, where a series of Ag-ZnPb mineralised, silica-rich vein, replacement bodies (mantos), skarn-altered embayment zones and breccias 2-10 m wide are located.
  • Fresnillo Plc. is realizing exploration work in the Guanajuato district, mainly near Mineral de La Luz.
  • Magna Gold Corp. initiated its phase one exploration program on the Mercedes project in Sonora. The aim on this phase is to confirm the existence (suggested by historical drilling) of an oxide zone of quartz stockwork Au-Ag mineralisation 60 m wide and 220 m long, and a surface study including geological mapping of a 500 ha zone and  systematic rock chip and soil geochemical surveys.


  • Torex Gold Resources Inc. reported Q2 2019 gold production of 113,600 Oz Au at its Limon-Guajes mine in Guerrero. Plant throughput averaged 11,670 tonnes per day (tdp), underground mine production was 1,280 tpd, open pit ore production was 18,600 tpd and the open pit strip ratio was 6.8:1.
  • Coeur Mining Inc. announced second quarter 2019 production. At Palmarejo, in Chihuahua, 447.7 K tonnes were milled @ 2.18 gpt Au, 147.4 gpt Ag, with recoveries of 87.7% Au, 81.8% Ag to produce 28,246 Oz Au, 1.7 M Oz Ag. Production at the La Nacion deposit began and is anticipated to add 400 tpd of mill feed.
  • Great Panther Mining Ltd. presented second quarter 2019 results including figures from its Mexican operations. At Topia, in Durango 18.4 K tonnes were processed @ 392 gpt Ag, 1.01 gpt Au, recovering 93.9% Ag, 58.9% Au to produce 218 K Oz Ag, 353 Oz Au, 453 tonnes Pb, 575 tonnes Zn. At the Guanajuato mine Complex, solely from the San Ignacio mine, 45.5 K tonnes were processed @ 2.52 gpt Au, 105 gpt Ag, recovering 85.5% Ag, 87.0% Au, to produce 388.4 K Oz Ag, 3,209 Oz Au.
  • GoGold Resources Inc. reported production results from its tailings project in Parral, Chihuahua. During the period 250 K Oz Ag, 2,281 Oz Au were recovered.

Endeavour Silver Corp. disclosed second quarter 2019 production results from its four mines in Mexico.
