ON MEXICO ISSUES

  • Gold production in Mexico declined by 2.8% in July 2019. This is the 28th consecutive month of production contractions, the longest since 1981, according to INEGI (Instituto Nacional de Estadística y Geografía). In 2016 the production declined by 5.2%, in 2017 another 13.6% and a further 9.7% in 2018. Mineral products with annual increments include zinc at 10.7%, iron pellets with 2.9%, lead with 2.5%, sulphur with 1.6% and coal with 0.8%.
  • On Peñasquito’s illegal blockade, Mexico’s president, Andres Manuel Lopez Obrador, asked both parties two solve their differences in the conflict that has now more than two weeks (he did not mention the blockade being illegal). Newmont Goldcorp has offered more than US$25 M in investments, amount that the blockaders reckon as lacking. The Peñasquito mine produced 272,000 Oz Au last year, and had re-started production in mid-June after a first illegal blockade by truckers wanting to get a contract and locals accusing the company of water availability issues.
  • To the 3rd of October Frisco and Cemex have suffered big losses in the Mexican stock exchange (S&P/BMV IPC), 13.76% and 6.24% respectively, under the current commercial instability between USA and the European Union. Frisco is one of the biggest mining companies in Mexico, with operations in Baja California, Sonora, Chihuahua, Zacatecas and Aguascalientes (although Frisco is also known for its scant releases on reserves and resources). Cemex is the biggest Mexican cement producer, with operations internationally.

ON EXPLORATION

The two mineral concessions cover 2806 ha underlain by a Precambrian basement composed of granite, gneiss, pegmatites and schist. “The entire sequence is affected by multiple deformations and the emplacement of intrusions such as leucocratic granites and andesitic dikes”. Gold mineralization is associated with quartz-breccia veins, quartz veins and “quartz stockworks emplaced along a series of parallel, foliated, low-angle shear zones within the igneous-metamorphic sequence”. Assays in an historical rock chip sample database have values of up to 230 gpt gold.
  • Colibri Resource Corp. contracted Auro Metallum Geology Consulting Services of Hermosillo, in Sonora, to complete a geological mapping study of its 506 ha Evelyn Gold Project near Caborca in Sonora. Recent sampling has returned up to 4.8 gpt Au from abundant quartz in sub-crop in a new zone identified by soil sampling.

  • Kootenay Silver Inc. signed a surface access agreement with the local ejido at the Copalito project in Sinaloa. Said agreement allows the company to mapping, sampling, geophysics, trenching and drilling. The 3,700 ha project covers a low sulfidation epithermal system with numerous veins, traced over up to 2 km of length, and 0.5 to 15 meters in width.

First Majestic Announce illegal Blockade at La Encantada

https://www.firstmajestic.com/news/index.php?content_id=324

TORONTO and NEW YORK, May 24, 2017 (GLOBE NEWSWIRE) — FIRST MAJESTIC SILVER CORP. (NYSE:AG) (TSX:FR) (the “Company” or “First Majestic”) announces that a rogue group of union workers have halted activities and blocked the accesses at the La Encantada Silver Mine in the state of Coahuila, Mexico. The illegal blockade arose after some of the unionized individuals did not agree with the bonus that the company and the National Union of Miners, Metallurgists, Steelworkers and Similar Workers of Mexico (National Union), agreed to offer the miners in lieu of profit sharing.

Despite an agreement with the National Union, this rogue group of workers unilaterally decided to form a blockade, which has disrupted operations for all of the mine’s employees. It is currently not known how long the blockade will continue, however, First Majestic is working with the leadership of the National Union in order to resume operations and have the workers return to work.

“It is very unfortunate that this group of individuals have chosen to react in this manner instead of through dialogue and the proper channels through its union leadership,” said Dustin VanDoorselaere, COO. “We have been working very diligently with the leadership of the National Union to provide a fair solution for all union employees.”
