ON MEXICO ISSUES

  • No Relevant News.

ON EXPLORATION

  • Golden Goliath Resources Ltd. reported the commencement of its summer exploration program at its San Timoteo property in the Uruachic district of Chihuahua. San Timoteo hosts the longest mining tunnel in the district, with mapping and sampling having defined three ore shoots and a manto horizon within it. No exploration has been carried below the level of the tunnel, and the workings are interpreted to be above the boiling zone of an epithermal system, hence the possibility of potential bonanza grades down dip.
  • Mexican Gold Corp. released high grade sampling results from the Pueblo Nuevo area of its Las Minas projects in Veracruz. Multiple new vein occurrences have been discovered in the Pueblo Nuevo Valley structural corridor. The veins “show characteristics of mesothermal quartz veins”, generally 20 to cm in width, sub-vertical dips and no post mineral deformation. The dioritic host rock displays argillic alteration and sulfides up to one meter on each side of the veins. Chip sampling results include 0.43 m @ 7.87 g/t Au, 74 g/t Ag, 3.5% Zn; 0.30 m @ 6.14 g/t Au, 60 g/t Ag, 5.3% Zn; 0.50 m @ 19.18 g/t Au, 229 g/t Ag, 2.25% Zn; 0.3 m @ 4.33 g/t Au, 30 g/t Ag, 1.1% Zn; 0.15 m @ 16.17 g/t Au, 101 g/t Ag, 0.6% Cu, 14.6% Zn; 0.60 m @ 3.18 g/t Au, 17 g/t Ag, 3.5% Zn; 0.40 m @ 4.11 g/t Au, 22 g/t Ag; 0.45 m @ 19.41 g/t Au, 148 g/t Ag, 1.5% Cu, 0.8% Zn; 0.60 m @ 19.26 g/t Au, 70 g/t Ag, 2.3% Zn; 0.75 m @ 10.12 g/t Au, 30 g/t Ag.

ON MEXICO ISSUES

  • Fernando Alanis Ortega, was appointed President of the Mexican National Chamber of Mines (CAMIMEX) for the period 2018-2010, replacing the outgoing Daniel Chavez Carreon.
  • CAMIMEX, reported that the investment in the mining sector reached $4,287 M USD in 2017. Although this represents an increase of 14.3% over the previous year, it is still 48.5% lesser that the invested record in 2012 which reached $8,043M USD.

ON EXPLORATION

  • Colibri Resource Corporation, reported drilling results from its El Pilar project in Sonora. Highlights are 9m of 8.16 g/t Au, including 1.5m of 33.4 g/t Au. The company has completed 2,117m in 20 RC holes “aimed to test for continuity within previously interpreted zones of mineralization, test for extensions to the known mineralization, and explore locally for new zones of gold mineralization”.
  • Azure Minerals Limited, provided an update on results from its El Alacrán project in Sonora, currently operated by Minera Teck S.A. de C.V. Teck drilled 14 holes to test extensions of Au mineralized zones at Loma Bonita area. Results suggest potential expansion of the Loma Bonita epithermal Au-Ag mineralized system at depth south towards Cerro San Simon, where four holes were drilled to test resistivity anomalies. Teck also drilled four holes at Cerro Colorado Zone to test mapped targets and geophysical anomalies generated by IP surveys and airborne magnetics, confirming potential for porphyry copper mineralization. Geological, geochemical and geophysical surveys are being carried out in H1, 2018 and will be followed by further drilling in H2, 2018.
  • Sable Resources Ltd., commenced a 4,000m diamond drill program to test 1.7km of Ag-bearing epithermal quartz veins at its margarita project in Chihuahua. The aim is to test for high-grade precious metal horizon 200m below mineralized surface samples.
  • Prospero Silver Corp., and Fortuna Silver Mines Inc., revised its 2018 exploration program, deciding to conduct a 6,000m drill program to test targets at its Buenavista, project in Durango, as well as at its Bermudez and Trias projects in Chihuahua.
