Highlights on the Second Week of March, 2018. Mining and Exploration News in Mexico

By Jorge Cirett

During the 10th week of the year (March 5th to March 11th, 2018), at least 24 press releases were announced by companies working in Mexico, and three articles on mining matters in Mexico published by newspapers. ON MEXICO ISSUES, the Fraser Institute released the results of the 2017 survey on Mining Attractiveness by Jurisdiction, with Mexico stagnant at mid table due to low results on taxation regime, labor disruptions and security perception. The Sonora government is supporting the mining industry with the signature of a collaboration agreement with the Economy Bureau. The governors of Chihuahua and Oaxaca attended the PDAC in Toronto for promoting mining investment in their respective states. Other delegations present were from Durango and Zacatecas. ON EXPLORATION, In Sonora Riverside announced a bigger land position at its Cecilia project; Oceanus has mapped the favorable El Tigre Formation rock package for 5 km in strike length at its El Tigre property; Mexus Gold updated on exploration of its 8 Hermanos property; Millrock disclosed interesting low grade drilling results from its Navidad property; Azure has started the second drill campaign at its Sara Alicia Au-Co property. In Chihuahua VVC Minerals received the permit for drilling its Samalayuca property; Radius updated on exploration at its Amalia project. In Guanajuato, Vangold started the phase two of drilling at its Pinguico property. ON MINING, two companies, Americas Silver and Santacruz Silver presented production results for the quarter and/or full year 2017. Magellan Gold announced the restart of its mill in Nayarit.  ON FINANCING, Canuc Resources closed a $1.1 M financing round, Colibri closed the first tranche of a financing round netting $1.08 M.

Autlan is to acquire all shares from Metallorum (it already controls an undisclosed percentage), which owns the Lluvia de Oro mine in Sonora.

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.

ON EXPLORATION

  • VVC Minerals Corp. received the permit for drilling at its Samalayuca property in Chihuahua. The SEMARNAT permit approved 22 new drilling sites, in addition to 13 already approved.

The completed and proposed drilling cover 7 Km of strike length on the property.
  • Vangold Mining Corp. concludes phase 1 drilling, starts phase 2 drilling at El Pinguico property in Guanajuato. Vangold completed five of 15 drill holes targeting the underground stockpiles (backfill) on the El Pinguico vein, with poor recoveries and grades. While a better method of assessing these stockpiles is researched, the company has initiated the phase 2 drilling campaign targeting the lower El Pinguico vein extension below the old workings, 300 m below the surface.
  • Riverside Resources Inc. announced that it has been granted the mineral rights to the Cecilia 1 concession, increasing the ground held on the Cecilia project in Sonora to almost 6,000 hectares. Epithermal Au-Ag mineralization is associated to a rhyolite flow-dome setting.
