  • No Relevant News.


  • SilverCrest Metals Inc. disclosed results from initial metallurgical sampling of mineralization from its Las Chispas property in Sonora. These results show that Las Chispas mineralization appears to be amenable to standard cyanidation processing, with average recoveries of 98.9% Au, 86.6% Ag. Nineteen core samples were combined into three bulk composites, with partly oxidized and non-oxidized material. Further metallurgical test work is to be completed after the announcement of a maiden resource in Q1 2018.
  • Auxico Resources Canada Inc. released metallurgical results from a 2 Kg metallurgical sample from a volcanic breccia in the footwall of the Campanillas mine, at its Zamora property in Sinaloa. The test returned 13.8% Au, 8.6% Ag recovery by gravity, 67.8% Au, 89.1% recovery by flotation, for total recoveries of 71.6% Au, 92.9% Ag.
  • Defiance Silver Corp. commenced a two-rigs phase II 5,000 m drill core program targeting new high-grade silver shoots along 900 m of the Veta Grande vein, SE from the San Acacio deposit in Zacatecas.
  • Golden Goliath Resources Ltd. received a report on its San Timoteo property in Chihuahua. The report stresses the presence of several strong systems of mineralized structures with potential for bonanza zones and a deeper Cu-Au porphyry system. Known zones within the Level 5 of the San Timoteo vein contain a 78 m long shoot @ 0.6 g/t Au, 68 g/t Ag and a 32 m long shoot @ 0.3 g/t Au, 212 g/t Ag.
  • Riverside Resources Inc. updated on exploration work in progress at its Glor property in Sonora, alongside its partner Centerra Gold Inc.. The work is focusing on the central part of the property, where samples of up to 14 g/t Au have been collected, with a detailed ground magnetic survey covering 210 hectares with 80 line-kilometers, 14 line-kilometers on an induced polarization survey, and an 850 sample soil program.
  • Prospero Silver Corp. received all necessary permits to carry a first-pass drill program at Bermudez, in Chihuahua. Prospero can now proceed with a drilling campaign funded by Fortuna Silver Mines Inc. to test a low sulfidation epithermal vein system exposed over a 2.5 km by 50-100 m area. Anomalous Au, Ag, Ba and Zn, along with the quartz vein textures support the interpretation of this being a shallow zone in the epithermal system.
  • Minaurum Gold Inc. released results from the first five holes (1,342 m) at its Alamos project in Sonora. Relevant intercepts on the Promontorio vein: 20.15 m @ 154 g/t Ag, 0.23 g/t Au, 0.5% Cu, 2.3% Pb, 6.8% Zn; 8.50 m @ 81 g/t Ag, 0.13 g/t Au, 0.1% Cu, 3.2% Pb, 2.7% Zn; 3.15 M @ 322 g/t Ag, 0.28 g/t Au, 0.5% Cu, 1.6% Pb, 3.3% Zn. At the Blind Vein/Southern Nueva Europa target an interval of 0.25 m @ 8 g/t Ag, 0.9% Pb, 2.4% Zn validated the idea of blind veins on the area. At the Minas Nuevas target the 17.65 m @ 96 g/t Ag and 13.05 m @ 54 g/t Ag intercepts confirm the potential for bulk-tonnage orebodies.

The optimization plan has resulted in drier mining conditions and significantly improved the cash cost and AISC per Ag Oz produced. The company is currently applying to become a “qualified user” under the recent energy reforms, which will allow Excellon to access the private market for electricity, a key cost on the water pumping to maintain dry mining conditions.
  • Alamos Gold Inc. reported its financial results for the third quarter of 2017, including figures from its Mulatos and El Chante operations in Sonora.

  • On Mexican Silver Production, Zacatecas has 40.8% participation, Durango 14.0% and Chihuahua 13.9%. Located in Zacatecas the Saucito mine is the largest primary silver producer in the world, generating 13% of the Mexican production. Silver production in Zacatecas decreased 11.5% in 2016, due mainly to lower grades at Peñasquito. In Durango, production decreased 23.7% by work interruptions at San Dimas and lesser output from Guanaceví. Construction of the La Preciosa (Durango), Pitarrilla (Durango), El Gallo II (Sinaloa), Cordero (Chihuahua) and Cerro del Gallo (Guanajuato) projects still await better market conditions to go ahead.

San Marco Identifies High Priority Drill Targets on the 1068 Project: Samples in Road Cuts up to 0.76% Copper, 2050 ppm Molybdenum and 0.17 g/t Gold

Vancouver, B.C. – September 26th, 2017  : San Marco Resources Inc. (SMN: TSX-V) (“San Marco”) announces the results and recommendations of recent exploration on its 1068 Project. The Project is an undrilled copper, molybdenum and gold porphyry system discovered from San Marco’s generative program (see news release dated January 19, 2017).

During construction of a preliminary access road to potential drill site areas, mineralization was noted in the roadway with copper values up to 0.76%, gold up to 0.17g/t and molybdenum up to 2050 ppm over 3 – 4 metre channel samples. Drilling is recommended after additional surface mapping and sampling is completed. Preparation for such work will commence immediately.

Exploration Highlights

Highlights of the exploration include;

  • Surface alteration and mineralized footprint has increased to 1.6 kilometres X 1.5 kilometres (“km”) and is open for expansion in at least two directions.
  • Poorly exposed erosional window into potassically altered mineralized intrusive (100 metres by 200 metres) is an obvious drill target.
  • Extensive phyllically altered and stockwork-quartz-veined volcanic lithocap (as above, 1.6 km X 1.5 km and open) may have created favourable conditions for sealing the system acting as a trap for fluids, enhancing the mineralizing process. Drilling through this volcanic cap is another obvious drill target.
  • Oxide copper occurs mainly in fractures and veinlets. Fresh sulphides (pyrite, chalcopyrite and molybdenite) were observed below the volcanic rock cap in potassic alteration.
  • Semi-continuous channel sampling over part of a newly constructed road cut ran 62 metres of 0.1% copper; 215 ppm molybdenum and 0.044 g/t gold. Sampling was limited to where the bulldozer was able to build the road and not necessarily cutting the best outcrop exposures.
  • Geochemical zonation suggests use of pathfinder elements as well as mapping alteration mineralogy can be utilized to vector to the best drill targets.


The period under review has been a time of continued operational progress as the Board looks to position the Group to create value from the existing asset portfolio and to take advantage of other convincing market opportunities that will create value for shareholders, whilst conserving cash.
The recent period has been characterised by a notable operational achievement with the issue of the final permits for the 3D seismic shoot in the Paradox Basin, Utah. In addition, considerable progress has been made with the ongoing process of disposing of the Group’s SDA Mill in Mexico and it is currently anticipated that, subject to
funding, both the seismic shoot and the disposal of the SDA Mill will be completed by 31 December 2017. The Group also continues to explore potential opportunities in Cuba, focusing on both the oil and gas and building materials sectors.
The primary focus of the next period will be on the Paradox assets. The Board is committed to unlocking shareholder value from the Paradox acreage with a view to the commencement of a drilling programme in the second half of 2018, following the completion of the 3D seismic shoot. The Board continues to believe that the outlook for U.S.A. energy is extremely encouraging, and that a strategic focus on the Paradox acreage is the optimal way to deliver short-term value to shareholders.
