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.

At Los Mimbres prospect, skarn and hornfels boulders with Cu and Pb sulphide mineralization were recently discovered adding a new target within the Yarely project. Mineralization identified at Los Mimbres is similar to that encountered at Metates. Stream sediment, soil, rock geochemistry and geological mapping are underway to advance this target to the drill stage.
  • Excellon Resources Inc., commenced a 3,000m drill program at its Miguel Auza project in Zacatecas to test targets generated from surface mapping, IP surveying, and structural work conducted since mid-2017 at El Cobre, Abejas, Carmen-Lechuzas, and Lomo de Las Minas prospects. Highlights from the surface sampling are 2.3 g/t Au and 667 g/t Ag at Lomo de Las Minas. Results up to 2.9 g/t Au and 300 g/t Ag were sampled at Carmen and El Cobre confirming mineralization in veins at both targets. Mineralization at Miguel Auza is hosted in epithermal quartz veins similar to those found at Fresnillo mining district.
