ON MEXICO ISSUES
- Mexico is to review the proposed bill to ban open pit mining, announced Claudia Shienbaum, Mexico’s president. The proposal was approved by the lower chamber of Congress in August, and also seeks to prohibit fracking and restrict water usage in areas of scarcity. She emphasized that the review will focus on ensuring environmental protection and is independent of corporate interests. “The Mexican Mining Chamber (Camimex) has voiced strong opposition to the proposed ban. Open-pit mining accounts for 60% of the value of Mexico’s national mining and metallurgical production. Camimex warns that the prohibition could lead to a 1% contraction in the country’s GDP and jeopardize nearly 200,000 jobs.”
ON EXPLORATION

ON MEXICO ISSUES
- Ken Salazar, USA ambassador in Mexico released a letter on which criticizes the Mexican president’s proposal for reform of the Judicial system. The ambassador pointed out the problems that will arise if the proposal is passed as is, bringing a major risk to democracy in Mexico and threaten the historic trade relationships with USA. (Note by editor. – The proposal envisages the selection system for federal judges and magistrates changing from one based on professional examinations to one based on the popular vote, among other bizarre directives aimed to control the judiciary system by the executive branch).
- Graeme Clark, Canada ambassador in Mexico stated that Canadian investors are at crossroads before the probable passing in Congress of the Judicial Reform proposed by the sitting president AMLO. According to CanCham (Cámara de Comercio de Canadá en México) 40% of Canada’s investments in Mexico are on the mining sector.
ON EXPLORATION
- Pantera Silver Corp. is currently evaluating options to restart exploration at the Nuevo Taxco project in Guerrero. “…work will likely focus on initial sampling and mapping in the “Southwest Zone” of the Nuevo Taxco concession”. Pantera Silver is pursuing potential acquisitions, aiming to build a portfolio of 2-3 high-quality projects, focused on silver.
- Colibri Resource Corp. reported results of geological mapping and outcrop sampling on 4,766 ha El Plomo property at the EP project, located 25 km east of Fresnillo plc´s La Herradura mine. At the San Perfecto target mineralization is hosted by a silicified and sericitized moderately to strongly foliated diorite with quartz micro-veinlets in higher-grade samples. Of 29 rock samples recently collected, 14 returned more than 0.1 gpt Au, 9 greater than 0.5 gpt Au and 6 with more than 1.0 gpt Au. More than 616 historical samples yielded results with over 50% above 0.1 gpt Au and 15% with more than 1 gpt Au, peaking at 58.9 gpt Au. “The footprint of mineralization at San Perfecto is now approximately 1,250 m by 700m”. At La Culebra target 34 grab samples were collected, with 14 returning more than 0.1 gpt Au and five more than 1.0 gpt Au peaking at 4.64 gpt Au. “Mineralization is hosted by rusty zones which were mapped over a 650 m strike length in a northeast direction and coincident with an andesite-rhyolite contact”.
- Radius Gold Inc. announced initial results on the exploration program at Plata Verde, in Chihuahua. The first four holes cut several zones of low-grade Ag mineralization “and indicate limited potential for an economic discovery in the eastern extension of silver mantos”. Assays are pending on four holes in the western side of the valley, with thicker favorable basaltic rock and improved visual mineralization. The most recent hole located further northwest “intersected visually improved results, cutting through greater width of basaltic host and encountering visibly the most attractive mineralization seen so far in this drilling program”. The JV partnership is extending the planned program, adding three additional drill holes.
ON MINING
- Endeavour Silver Corp. informed processing resumed at the Guanacevi mine in Durango, after the primary ball mill trunnion failure. Temporary modifications re-purposed one of the re-grind mills as the primary ball mill, which is running at 400 tpd (name plate capacity 1,200 tpd) during this temporary phase. “Contract mining activities and local third-party material purchases will cease until the process plant operations have returned to full capacity”.
