ON EXPLORATION

  • Riverside Resources Inc., completed 11 N-S lines for soil sampling which returned strong multi-elements anomalies with Au, Pb, Cu, and other key elements. These results along with previous exploration work have outlined four new target areas on its Cecilia project in Sonora. Target 1 is a 4km long by 300m wide target where previous rock sampling has found up to 2 g/t Au in silicified conglomerates , but the soil anomaly is open in both directions beyond the 4 Km and more than 800m wide. Target 2 is a NE trending Ag, Pb, Au, Zn, Sb, Hg and Cu soil anomaly over 2km long and 600m wide in rock cracks with faults and host veining displaying a series of NW striking feeder dikes. Target 3 is a 1km long by 500m wide Au-Zn with minor Ag, Cu, Pb and Bi soil anomaly associated to a N-S trending fault system intersecting Paleozoic limestones. This target is also along the border edge of a magnetic high reported in a regional government geophysics survey likely associated with Pre Cambrian granitic basement.  Target 4 contains “high-grade gold samples in soils and alteration with jasperoid, silicification, and carbonate veining of the Paleozoic limestone that gives a potential limestone hosted Au with anomalous soil assays of Zn, Pb, Ag and Mn”.
  • Kootenay Silver Inc., announced that its partner Capstone Mining Corp., has commenced an exploration program on its la Mina project in Sonora. The exploration program will consists of detailed mapping and rock chip / stream sediment sampling to generate potential drill targets.

ON MEXICO ISSUES

  • Mexico stays about the same on the investment attractiveness index published yearly by the Fraser Institute. Mexico fell to the 50 (of 91 jurisdictions surveyed) position from the 44 (of 104) on the 2016 survey, affected mainly by low rankings in security, taxation regime and labor regulations/work disruptions. In 2014 Mexico was on the 24 position of 122 surveyed. Chile ranked 8 and Peru 19 on the 2017 survey. Below is the table for the perception of the taxation regime (which presents the effect of the recently imposed royalties as a hard fact). The security perception ranking, along the other rankings can be seen at the following link: (https://www.fraserinstitute.org/sites/default/files/survey-of-mining-companies-2017.pdf).Taxation Regime Index, Fraser Institute 20171
  • The Sonora government is supporting the development of the mining industry in the state with the signature of a collaboration agreement with the Economy Bureau (Secretaría de Economía). The agreement looks to promote investment, better technical assessments, training and cut red tape. The mining industry represents 17% of the state’s GDP, with the state providing 31% of Mexico’s mining production. Sonora’s Governor Claudia Pavlovich has been pushing a proposal on the Deputies Chamber to install a 100% deduction of exploration expenses on the year these are incurred.
  • The governors of Chihuahua and Oaxaca attended the PDAC in Toronto Canada to promote mining investment on their states. Both Javier Corral (Chihuahua) and Alejandro Murat (Oaxaca) attended the Mexico Mining Day 2018 and had personal interviews with companies doing business in their states or trying to set a foothold there. Other delegations present were from Durango and Zacatecas.
