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 EXPLORATION

  • Canuc Resources Corporation, reported sampling results from its San Javier project in Sonora. Significant results from the northeast section of the San Javier mineralized corridor are 1.5m of 625 g/t Ag in breccia material at the Chiripas working and 3.8m of 477 g/t Ag in vein material at the Little Pit working. In the southwest portion at the Jazmin old working sampling returned 2m of 698 g/t Ag in vein material. “These results clearly indicate that high grade silver vein mineralization, and also silver bearing breccia geology, is evidenced along the full 3 km strike extent of the San Javier structure and the San Javier mineralized corridor. This is very encouraging for geological prospects and vein continuity along trend in the northeasterly direction, and suggests potential for a robust high-grade and vein hosted mineral endowment.” Canuc also announced the release of two of the nineteen claims optioned in san Javier property.
  • Azure Minerals Limited, reported drilling results from its Oposura project in Sonora.

ON RESOURCES AND DEVELOPMENT

  • Alio Gold Inc., initiated the construction of a 1,200m underground decline at its Ana Paula project, which is expected to be completed in Q3 2018. It will enable commencement of the first phase of the proposed underground diamond drill program, which will consist of 12,000 m in 55 holes. The company completed a six-hole 3,800m drill program below the proposed open pit to better define the geometry of the complex high-grade breccia and know the mineralization extent. Alio is also currently carrying out a drilling program on a high priority surface target 150m north of the proposed open pit, on which a detailed geological mapping at a scale 1:2,000 will be conducted.
  • Hecla Mining Company, provided and exploration update on its San Sebastian mine in Durango. An Infill drill program is been conducted to expand high-grade polymetallic zones similar to the Hugh Zone on the Middle and Francine veins, as well as oxide mineralization along the Professor and Francine veins. Significant results are 1.34m of 135 g/t Ag, 23.5% Pb, 18.5% Zn, and 7.9% Cu on the polymetallic zone, and 1.58m of 1,200 g/t Ag and 4.98 g/t Au on the oxide mineralization. At West Middle vein, the most significant intercepts are 1.34m of 317 g/t Ag, 10.1% Pb, 18% Zn, and 3% Cu, and 0.85m of 304 g/t Ag, 8.5% Pb, 9.4% Zn, and 3.8% Cu.
  • Mexican Gold Corp., reported step-out drilling results from the El Dorado / Juan Bran and Santa Cruz zones within its Las Minas projects in Veracruz. Significant interceptions are 8m of 1.06 g/t Au and 6 g/t Ag, including 6m of 1.36 g/t Au and 8 g/t Ag; 6m of 2.52 g/t Au and 10 g/t Ag; 14m of 1.96 g/t Au and 0.3 g/t Ag, including 6m of 3.49 g/t Au and 0.5 g/t Ag; and 24m of 1.24 g/t Au and 3 g/t Ag, including 10m of 2.12 g/t Au and 4 g/t Ag. The drill results tested the continuity of mineralization at El Dorado / Juan Bran zone and extended the mineralized zone to depth as well as cutting multiple mineralized intervals in the upward extension of the Santa Cruz zone.
  • Leagold Mining Corporation, reported underground drilling results for its Los Filos mine in Guerrero. Highlights are 4.1m of 24.2 g/t Au, 6.95m of 23.6 g/t Au, and 9.1m of 8.7 g/t Au from the Nukay, Conchita and Creston Rojo deposits respectively. The aim of the drilling program which comprises over 12,000m to date from 62,000m planned for 2018 is to identify additional resources along the contact of the circular intrusive orebodies.
  • Premier Gold Mines Limited, filed a technical report to release  updated mineral reserves for its Mercedes Mine in Sonora, with 3.3M tonnes of 3.94 g/t Au containing 417K Oz Au, and measured and indicated mineral resources for 3.68M tonnes of 4.32 g/t Au containing 511K Oz Au.
  • Sierra Metals Inc., reported mine development at its Cusi and Bolivar mines in Chihuahua during Q1, 2018. At Cusi, mine development totaled 676m. The company also carried out 1,448m of underground infill drilling, and 7,398m from surface. At Bolivar, mine development totaled 1,177m, with 650m to prepare stops for mine production, 466m to deepening ramps and developing service ramps for ventilation and pumping, and 61m of raises.
  • US Antimony Corporation, reported progress on the construction of the leach plant for the Los Juarez Au-Ag-Sb deposit in Queretaro. Testing and shake-down of the plant is anticipated in Q4 2018.
