The ground magnetic survey has been completed, with data being currently processed.
- Silver Viper Minerals Corp. has halted exploration activities for the duration of the local hunting season (land access agreement) at its Clemente project in Sonora. Work is to continue in February 2018. During 2017 reconnaissance mapping, soil sampling and diamond drilling of nine holes were completed. Full assays from the drilling are pending, and will be released once available.
- First Majestic Silver Corp. announced third quarter 2017 financial results. During the period 730.6 K tonnes were processed to produce 2.42 M Oz Ag or 3.99 M Oz AgEq at cash cost $8.52 per AgEq Oz and AISC of $15.73 per AgEq Oz. Cash and cash equivalents were $120.8 M at the end of September.
- U.S. Antimony. Reported that SEMARNAT (Mexico’s environmental agency) issued the permit for a cyanide plant for the Puerto Blanco mill in Guanajuato. The plant is designed to recover Au and Ag from the pilot mill tailings of the Los Juarez Au-Ag-Sb deposit in Queretaro. Construction of the leach circuit has commenced.
- Firma Holdings Corp. provided an update on its activities. In the 10,000 hectares Don Roman project in Sinaloa, Firma entered into an agreement with a third party to refurbish the 360 tpd flotation mill and the development of the Rosario historic Zn-Pb-Ag mine. The agreement envisions a $250 K to $600 K investment to earn an expected 10% net cash flow interest. Firma also entered into an agreement with a third party to fund the acquisition of the 100 hectares Saucillo project in Sinaloa. An investment of $275 K is to earn a 10% net cash flow interest. All $275 K has been received, with $200 K used to be used to buy the property and the rest to produce a 300 tonne bulk sample. The Magistral tailings project in Durango is managed as a 50/50 joint venture with MX Gold is nearing completion on the construction of a 1,000 tpd Meryl Crow recovery plant.
- Avino Silver & Gold Mines Ltd. received conditional approval to graduate from the TSX Venture Exchange (TSX-V) and list its common shares and warrants on the TSX. Final approval is subject to Avino meeting certain standard requirements before February 27, 2018 (Avino, Durango).

A 2,000 m drill program for metallurgical sampling and confirming grade and lithology of the resource was completed, with one hole returning 24.9 m @ 6.1 g/t Au (including 4.4 m @ 27.2 g/t Au). The construction of the portal site for the underground decline commenced, and underground equipment was mobilized to the site. A 4,000 m surface drilling program was initiated on the deeper high-grade breccia extension before the definitive feasibility study (DFS), and to test a priority target north of the current pre-feasibility pit.
- Marlin Gold Mining Ltd. announced positive drill results from the Colinas target area, less than 1 km from the Taunus pit at its La Trinidad mine in Sinaloa. “The drilling at Colinas has focused on an area that is amenable to open pit mining along a southeast trending structural corridor, which is interpreted to be an extension of the structure that controls gold mineralization in the Taunus pit”. Relevant core length intercepts include 7.20 m @ 4.65 g/t Au (starting 7 m below the surface); 34.65 m @ 0.65 g/t Au.
- Silver One Resources Inc. commenced a geophysical survey at its Peñasco Quemado silver property in Sonora. The controlled-source audio-frequency magnetotellurics (CSAMT) being used will probe deeper with higher resolution than previous surveys, with the purpose of developing a 3-D map of lithology in areas with strong Zn-Pb responses in soil geochemistry. The Peñasco Quemado project has a measured and indicated resource of 10 M Oz Ag, recognized from drilling in 2008 and 2009.
- Minera Alamos Inc. informed that data compilation and reviewing revealed La Pista zone 1,300 m SW of the La Fortuna gold resource, where shallow drill holes hint near surface disseminated Au-Ag mineralization with heap leach style intervals up to 50 m in width. Recent sampling in the area has returned up to 8 g/t Au, 30 g/t Ag over a mineralized area of 500 m x 300 m. The first phase of new exploration drilling is planned for early 2018, focusing on extensions of the La Fortuna main zone, the PN area and the La Pista area.
