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.

The initial option to earn 70% lies on Sinaloa issuing shares for $1 M, $60K in cash payments and exploration work commitments of $3 M over 36 months. To earn an additional 30% Sinaloa must spend a further $1 M in exploration and issue Riverside $500 K in shares. Riverside is to retain a 2.5% NSR if Riverside’s interest reduces to less than 10%. Previous work in the 2,071 hectares project includes 6 drill holes on the El Roble system, with intersects of up to 15 m @ 6.9 g/t Au.
  • Riverside Resources Inc. announced that drilling assays from two campaigns funded by Centerra Gold Inc. returned insufficient mineralized thickness and continuity to justify further exploration on the Glor project in Sonora.
