ON MEXICO ISSUES
- Researchers discovered 12,000 years old submerged ochre mines in the Yucatan peninsula. Multiple artifacts and evidences of mining were found in this cave system that was above sea level up to 8,000 years ago.
- Avino Silver & Gold Mines reports that members from the Mexican mining union have blocked the entrance to the Avino Mine in Durango. The group (that illegally blockades) includes the company’s unionized workers. As a result of the strike at the site, mining and mill processing operations have been halted.
- Mining in Mexico supports 696 communities in 21 States, and often is the only option to take basic services and jobs to regions far away. The mining sector provides 2.6 percent of the GDP and accounts for 8.2 percent of the industrial output. Salaries at US$779/month (17,521 pesos/month) are 39 percent higher than the national average of $513/month (11,549 pesos/month). There are 379 thousand direct jobs and 2.3 M indirect jobs generated by the industry. Mining paid US$1.91 billion ($43,095 million pesos) in mining concession fees in 2019, and US$7,755 billion ($174,500 million pesos) in taxes in the 2016-2019 period.
- The Mining Fund rules have been changed. The changes in the rules were published in the Diario Oficial de La Federación (Official Gazette), with the aim of speeding the process to deliver benefits to the communities, according to the document. The changes (which were opposed by the mining community because of the increased political control of the funds) include the elimination of necessary cost-benefit assessment of the projects deemed for social infrastructure, discarding also the obligation to establish coordination agreements in the request and delivery of said funds. The Mining Fund distributes part of the 7.0% of royalties and the 0.5% special tax on precious metal exploitation.
- Mines in all the country prepare for a production recovery in the second half of 2020, as all companies have scrambled to operate under health safeguards brought by the Coronavirus pandemic.
ON EXPLORATION
- Advance Gold Corp. provided an update on exploration of its Tabasqueña property in Zacatecas. The exploration that started trying to define epithermal vein mineralization has modified its target to a volcanogenic massive sulfide (VMS). A large chargeability anomaly more than 3 km long was defined in a geophysical survey, and subsequent drilling has intersected disseminated sulfides. Drilling of the disseminated sulfides has returned up to 39 ppb Au, 7 ppm Ag, 351 ppm Cu, 54 ppm Pb, 295 ppm Zn.
- Brigadier Gold Ltd. entered into a binding letter of intent with Minera Camargo S.A. de C.V. for an option to acquire 100% interest in the Picachos property in Sinaloa. The area has more than 160 known historic underground workings, a recently identified porphyry copper prospect and drill permits in place. “The largest vein system trends northeasterly for seven kilometers along a major fault zone, and host the past-producing San Agustin underground mine”. Regional stream sediment results from a government survey shows several highly anomalous basins with up to 2.6 ppm Au, 299 ppm Cu, 13.9 ppm Mo, 639 ppm Pb and 1,716 ppm Zn.

The corridor “ hosts two main quartz veins that are separated by some 10 to 20 metres and appears to dip very steeply to sub-vertical. So far it has been mapped along strike for over 2,000 m. Between the two main veins are a series of smaller splay veins with variable orientations, that are related to dilation along the structure under strike slip movement …. Vizsla has an option to acquire 100% of the newly-consolidated 9,386.5 Ha Panuco district in southern Sinaloa, Mexico, near the city of Mazatlán. The option allows for the acquisition of over 75 km of total vein extent, a 500 tpd mill, 35 km of underground mines, tailings facilities, roads, power and permits”.
- Tarachi Gold Corp. updated on field work activities on the concessions known as the Tarachi project, in Sonora.

First Majestic has taken steps to sue the federal government under provision of chapter 11 of NAFTA, on grounds of double taxation. ON EXPLORATION, in Sinaloa, Vizsla Resources released results from seven historic holes from the Plomosas Mine area at its Plomosas project.

ON MEXICO ISSUES
- Camimex informed 23 mining companies working in Mexico have supported 16 States in the country, with activities and donations of medical supplies to aid communities in the Coronavirus emergency. Mexico was the only country in North America that did not place mining within the essential industries to continue activities during the lockdown.

- Adding to the confusion on government announcements, the sub-secretary of health prevention and promotion Hugo López Gatell informed mining, construction and automobile industries are to start activities until 01 June 2020. Most mining companies had already announced the commencement of activities on 18 May, 2020, as the mining industry had been declared essential, a term which has allowed other industries to continue activities during the Coronavirus emergency. In this twist of events, the sub-secretary said these industries can prepare for starting work on 01 June, 2020, and that further notice on physical modification of workspaces, schedules, and distance between workers, among other regulations to be announced on 18 May, 2020.

In mining we return to operate adhering to strict protocols and sanitary measures: since the people leaves home until they return”.

The Supreme Court also has to rule in the case of Puebla’s indigenous communities against the granting of mining concessions in their ground.

The company claims the SAT (Servicio de Administración Tributaria, equivalent to the IRS in USA), has shown a strong deviation from several international treatises on double taxation. “The service of this Notice by the Company on the Government of Mexico initiates a 90-day process for the Government of Mexico to enter into good faith and amicable negotiations with the Company to resolve the current dispute”.
ON EXPLORATION
- Vizsla Resources Corp. released drilling results from seven holes on the Honduras vein and surface and underground sampling of the Animas, Cordon de Oro and Napoleon vein corridors at its Panuco project in Sinaloa.
