Highlights on the Fourth Week of January, 2017. Mineral Exploration in Mexico

During the 4th week of the year (23rd to 29th January, 2017) at least 18 press releases were announced by companies working in Mexico, including one preliminary production report for 2016. ON EXPLORATION, four companies presented exploration updates. One company with mines in, Jalisco, Durango and Guanajuato, and advanced properties in Chihuahua, Jalisco and Zacatecas is to drill 64,000 meters in 2017. In Sonora trench sampling results were released from a lithium property. In Chihuahua results of a PIMA-XRD survey on a high sulfidation property were released. Underground samples returned high grade silver values on a vein system in Zacatecas. ON MINING, Avino Silver and Endeavour presented production guidance for 2017, and Fresnillo increased silver production during 2016.  ON FINANCING, Four companies conducted financial operations, for a hefty total of $358.35 M, with the majority arising from Fortuna Silver and Alamos Gold bought deals. ON RESOURCES AND DEVELOPMENT, one company reported high grade step-outs on its Mexico State mine. In Chihuahua metallurgical results were presented for a silver property. In Durango a PFS was presented on one property, while a maiden resource was presented for another one.  ON DEALS AND CORPORATE ISSUES, the last installment to earn an interest on a tailings property in Zacatecas was completed.

ON EXPLORATION

  • Arian Silver Corp. released results from exploration at its La Africana property in Zacatecas. Consistent high grade results from underground sampling range 200 – 1,200 g/t Ag, with Pb and Zn credits. Sampling results include 2.4 m @ 445 g/t Ag, 0.28% Pb, 0.49% Zn; 4.97 m @ 260 g/t Ag, 0.2% Pb, 0.37% Zn; 3.45 m @ 184 g/t Ag, 0.65% Pb, 0.34% Zn; 4.46 m @ 178 g/t Ag, 0.33% Pb, 0.44% Zn; 3.35 m @ 198 g/t Ag, 0.67% Pb, 0.29% Zn; 4.95 m @ 319 g/t Ag, 0.71% Pb, 0.37% Zn.
  • Alix Resources Corp. presented trench sampling results from the Agua Fria zone of the Elektra project in Sonora, which include 146.5 m @ 712 ppm Li, 2.6% K; 30 m @ 954 ppm Li, 2.1% K; 103.2 m @ 758 ppm Li, 2.3% K. Also metallurgical testing has commenced on Li enriched clays, with 24 trench samples sent for assessment. On the Agua Fria North zone, nine channel samples averaged 1,069 ppm Li, with a peak of 1,340 ppm Li.
  • Endeavour Silver Corp. plans to drill 64,000 metres and spend $15.2 M on brownfield and greenfield exploration, development engineering and land payments on its properties. At El Compas in Zacatecas, a $3 M exploration budget includes 3,000 m of drilling and an 800 m long exploration adit. At Terronera in Jalisco, the $2.3 M budget is to cover 10,000 m of drilling to test other mineralized veins, complete the PFS and advance site infrastructure. At Parral $3.0 M are to drill 18,000 m to confirm a portion of the historical resource, testing multiple greenfields high-grade and bulk tonnage silver targets. A 5,000 m drill program will be conducted at Guadalupe y Calvo in Chihuahua.
  • Mammoth Resources Corp. reported results from its PIMA-XRD surface program at its Tenoriba property in Chihuahua. According to the company, 202 samples were collected on 14 lines 1 – 2 km in length, separated 500 m of each other; the dickite, pyrophyllite and smectite signatures define some corridors with greater favorability to contain economic gold mineralization in the high sulphidation epithermal environment. Tighter line spacing is to follow in to the Carneritos and Moreno zones, and expansion of the survey to other targets.

ON MINING

  • Avino Silver and Gold Mines Ltd. summarized 2016 operations, and provided guidance for 2017. At Avino and San Gonzalo mines 1.6 M Oz Ag, 7,119 Oz Au and 4.2 M Lb Cu were produced during 2016. Commercial production on the Avino mine commenced on April 1st , 2016, a new power line was completed and construction of a new tailings storage facility was initiated. For 2017 capital expenditures at the two mine sites is estimated USD$12.2 M, including a mill expansion, mining equipment, tailing storage facility and exploration.
  • Endeavour Silver Corp. provided 2017 production and cost guidance for its Guanaceví (Durango), Bolañitos (Guanajuato) and El Cubo (Guanajuato) mines. At Guanaceví 1.0 – 1.2 K tonnes per day (tpd) will be processed, to produce 2.4– 2.6 M Oz Ag, 5.3 – 6.3 K Oz Au; at Bolañitos 1.0 – 1.1 tpd are to be processed to produce 0.9 -1.0 M Oz Ag, 21.5 – 22.5 K Oz Au; at El Cubo 1.3 – 1.5 K tpd will be processed to produce 1.9 -2.1 M Oz Ag, 50.0 – 53.0 K Oz Au. Cash cost is expected to be $6.50 – $7.50 per silver ounce, net of gold by-product credits, and AISC on the same basis is estimated to be $14 – $15 per silver ounce. Investments for $43.3 M are planned on capital projects, primarily for mine development (16.7 km) to access reserves and resources.
  • Fresnillo PLC produced 50.3 M Oz Ag during 2016, a 7.1% increase year on year, and established a production goal of 58 – 61 M Oz Ag for 2017 from its six mines in Mexico. The increase in 2016 was supported by initial production from San Julian, in Chihuahua, and higher silver grades at Ciénega in Durango and Fresnillo in Zacatecas.
