In Sinaloa, Santana Minerals disclosed high-grade historical assays from the Lupita prospect, in its Cuitaboca project.  ON MINING: Mag Silver, Leagold Mining, Primero Mining and Starcore International presented quarterly results. Vangold Mining informed of a sampling program to measure the backfill resource at the Pinguico property in Guanajuato. Telson Resources delivered the first concentrates from Campo Morado, in Guerrero. In Zacatecas, operations at Santacruz Silver’s mill in Vetagrande, Zacatecas were suspended by PROFEPA. ON FINANCING: This was definitely a good week, with six companies reporting the opening or closing of financing rounds: VVC Exploration, Over CA$2.6 M; MAG Silver, $48.16 M; Kootenay Silver, $4 M; Gainey Capital, $717.8 K (for a total of $1.96 M). ON RESOURCES AND DEVELOPMENT: Mexican Gold Corp released high grade results from four step out holes at its Las Minas property in Veracruz. Consolidated Zinc is modifying its plans to mill over 250 K tonnes per annum at its Plomosas property in Chihuahua. Silver Bull released high-grade Ag-Cu drill results from drilling the sulfide zone at its Sierra Mojada property in Coahuila. Oceanus disclosed high-grade results from the first hole on its new drill campaign at El Tigre, in Sonora.  ON DEALS AND CORPORATE ISSUES: Argonaut Gold is to acquire the Cerro del Gallo property in Guanajuato, from Primero mining, for US$15 M, including VAT.


  • PROFEPA (Mexico’s environmental enforcement agency) temporarily suspended operations at the Vetagrande mill in Zacatecas, citing inadequate atmospheric emission controls. Santacruz Silver Mining Ltd. failed to present an environmental permit, equipment maintenance registers or an inventory of atmospheric emissions. Primero Mining received VAT refunds from the SAT (Servicio de Administracion Tributaria) of $4.6 M during Q3, and $10.6 M during October.


  • Alset Minerals Corp. staked and filed mineral claims for over 400 K hectares of prospective lithium-rich salars in Coahuila. The claims contain the dry lagoons of Mayran (one of the biggest dry lakes in Mexico), Viesca and Los Remedios, in an area of 150 km (N-S) by 125 km (E-W). At Viesca there is history of commercial brine extraction by Sulfatos de Viesca.
  • Aztec Minerals Corp. along with partner Kootenay Silver Inc. announced that phase one of the drilling program is underway at its Cervantes project in Sonora. The program consists of 3,000 m on 14 to 17 holes to test: 1) A gold anomaly in soil and rock chip surveys 600 m by 900 m over quartz-feldspar porphyry and intrusive breccias at the California prospect. 2) Au-Cu mineralization on the Jasper target. 3) A geophysical chargeability/resistivity anomaly.
  • Colibri Resource Corp. is changing the mineralization model at its El Pilar project in Sonora. The mineralization is hosted in andesites along the contact with a granodiorite, but recent drilling confirmed that a supposed strike slip fault is not present, increasing the potential for gold carrying pyrite rich zones associated to two structures in the andesites. New drill targets have been defined, with chargeability anomalies also to be tested.
  • Silver Spruce Resources Inc. has restarted the permitting process for initiating a drill program at its Pino de Plata project in Chihuahua. Drill companies have visited the 397 hectares property and are to submit bids on the drilling program that is to test three zones. The El Terrero target consists of disseminated epithermal mineralization in intrusive rocks, with grab samples of up to 557 g/t Ag. The Teodora vein targets have verification samples with up to 553 g/t Ag. The Santa Elena target area shows replacement Ag-Pb-Zn-Cu mineralization.
  • Endeavour Silver Corp. discovered additional potential bulk tonnage silver mineralization in the Palmilla area of its Parral project in Chihuahua. “ Endeavour drilling has outlined lower grade, bulk tonnage mineralization above and along strike of the old workings that may be amenable to open pit mining”. The true width mineralized intervals averaged 10.1 m @ 92 g/t Ag, 0.2% Pb, 0.4% Zn (Each mineralized interval on one of the Capuzaya, Palmilla and La Luz veins). Endeavour has already an historic resource at the Veta Colorada vein, and is continuing with drilling at the San Patricio vein. A new resource for the Parral property is to be released by Q1, 2018.
  • Santana Minerals Ltd. disclosed a review of historic data that shows high-grade silver mineralization in the La Lupita prospect, part of its Cuitaboca project in Sinaloa. Of a total of 24 samples collected by Peñoles in a 130 m long stretch, nine returned values between 200 g/t Ag and 786 g/t Ag, with an average (on the 24 samples) of 220 g/t Ag, 0.3 g/t Au. Previously reported saw channel sampling by Santana on the same zone returned 7 m @ 161 g/t Ag, 1.1 m @ 158 g/t Ag, 2.9 m @ 281 g/t Ag, 1.65 m @ 514 g/t Ag.


  • Vangold Mining Corp. started a grading and sampling campaign on the surface 200 K stockpile at its Pinguico property in Guanajuato. The company also intends to clean the underground workings in order to access and sample the mine back fill, which they estimate to have the potential to reach 500 K tonnes. The back fill comprises material that did not reach the 15 g/t Au cut off that was being mined in 1913. Both above ground and underground material is to be tested metallurgicaly to define processing methods.
  • Mag Silver Corp. released its third quarter 2017 financial results. During the quarter underground development has been intensified to allow for a planned increase to 4,000 tpd in mining rate, permitting is in process for the planned production increase, and a 20,000 m exploration drill program commenced in July, with three rigs on the surface and one underground. An independent feasibility study (FS) is due by early 2018. The company had $121.6 M in cash and cash equivalents at the end of the period. A new expanded resource estimate was presented on November 7, 2017.
  • Telson Resources Inc. delivered the first zinc concentrates produced at its Campo Morado mine in Guerrero, to Trafigura’s warehouse in Manzanillo, Colima. Up to the first week of November, Telson has produced more than 800 tonnes of zinc concentrate and more than 250 tonnes of lead concentrate.
  • Leagold Mining Corp. reported Q3 2017 production from Los Filos in Guerrero. During the quarter 7,6 M tonnes were moved and 2.1 M tonnes of ore mined @ 0.67 g/t Au, 98 K tonnes were mined from underground @ 7.43 g/t Au, with a recovery rate of 70% (estimated at 80% from underground material) to produce 47,766 Oz Au at an all-sustaining cost (AISC) of $993. An expanded resource estimate for the Bermejal underground deposit was released, and 38,581 m of a 56,000 m drilling campaign were also completed. The company held $52.9 M of cash and cash equivalents at the end of the period.
  • Primero Mining Corp. reported operating and financial results for the third quarter 2017. At San Dimas in Durango, 110.2 K tonnes were mined and 114.7 K tonnes milled (1,246 tpd) @ 4.78 g/t Au, 301 g/t Ag, recovering 97% Au, 94% Ag, to produce 17,070 Oz Au, 1.1 M Oz Ag (or 20,537 Oz AuEq), at cash cost $884 AuEq and AISC of $1,117 per ounce. Production at San Dimas was affected by persistent issues with underground equipment reliability which impacted development and stoping, and a strike by unionized workers over the negotiation of the 2016 annual workers’ bonus. Cash at end of period was $14,9 M, which increased to $22 M by the end of October.
  • Starcore International Mines Ltd. announced production results for the second quarter of fiscal 2018, ended on October 31st, 2017. During the quarter 69.7 K tonnes were milled @ 1.56 g/t Au, 13.6 g/t Ag, recovering 80.9% Au and 54% Ag, to produce 2,739 AuEq Oz. the Altiplano Facility received 137.2 K tonnes of concentrate and 311 Kg of precipitates containing 197 Oz Au, 13,650 Oz Ag.
