  • The Mining Fund is gone for good from the purpose it was created for: aiding the development of mining communities. Mining States and municipalities wonder what the destiny of more than $1,500 M pesos actually in the Fund. The actual federal government re-directed the use of the Mining Fund, with 85% going to the Education Secretariat, 5% to the Economy Secretary and 10% to federal government infrastructure programs.
  • A new special force for overseeing mining operations was formed by the federal government. The first 118 guards graduated from a special training course, and will be equipped with assault weapons. Heists by organized crime have plagued the industry in the last few years, with robberies of bullion in mining operations across several states.
  • The Economy Secretariat informed mining concessions cover only 9% of Mexico. Graciela Marquez, Secretary of Economy noted that 24 thousand current mining concessions cover 17 M hectares. The Director de Minas (reporting to Gabriela Marquez) pointed that they are following the president view of not granting more mining concessions, which is problem that will catch up in 10 years’ time with fewer new deposits to mine due to the lack of exploration.
  • The Confederacion de Trabajadores de Mexico (one of the largest union organizations in Mexico, best known as “CTM”) asked the federal government and the Deputies Chamber for the no disappearance of the Mining Fund.
  • Fernando Alanís Ortega from Camimex pointed out some 150 junior exploration companies have left Mexico due to the complex operative environment. Several companies have diversified their operations this year, with acquisitions in Canada and USA. The last company to divest its Mexican portfolio is Silver One, to focus on a project in Nevada.
  • The Mexican index of Mining-Metallurgic production increased by 6.2% in July, compared with the same month of 2019 and by 5.1% from July 2020 to the previous month.
  • Sixteen Municipalities in Hidalgo are to receive $48 M pesos from the Fund for Development of Mining Production Zones.  


  • Brigadier Gold Ltd. commenced its maiden drill program at the 3,954 ha Picachos property in Sinaloa. The drilling of 5,000 m in 40 holes will test the San Agustín mine (underground rock chip sample of 1.2 m @ 73.4 gpt Au), and the the Mochomos (underground rock chip sample of 0.5 m @ 18.5 gpt Au, 570 gpt Ag), Tejones (underground rock chip sample of 1.0 m @ 28.6 gpt Au, 114 gpt Ag) and Fermin (underground rock chip sample of 1.0 m @ 0.3 gpt Au, 268 gpt Ag) veins. “the Cocolmeca Vein system is comprised of several sub-parallel veins over a 1.5 kilometre (km) wide zone ……  San Agustín is the best understood of these veins, mainly because it has been historically exposed underground by approximately 670 line-metres of tunnels, stopes and shafts”.
  • Colibri Resource Corp. received results from a high-resolution magnetic survey at its Evelyin property in Sonora. The interpretation of the magnetic data allowed the identification of three families of lineaments that are to aid in the definition and prioritization of targets.
  • Tocvan Ventures Corp. informed on new interpretations on all the information gathered on its Pilar project in Sonora. With the aid of geophysical, geochemical and structural specialists a conclusion was reached that a sub-vertical pipe-like feature may represent a breccia feeder pipe related to epithermal mineralization. The pipe is close to 100 m in diameter, oval shaped and dipping 70 degrees to the SSW.
  • Mithril Resources Ltd. Released results from nine more holes at La Soledad in the Copalquin project, Durango. Drilling confirmed the bonanza grades of the La Soledad vein and intercepted additional veins at depth and along strike. Highlighted results comprise 3.8 m @ 2.58 gpt Au, 143 gpt Ag; 0.5 m @ 6.78 gpt Au, 10 gpt Ag, an open working for 2.5 m and then 1.5 m @ 6.65 gpt Au, 18 gpt Ag; 2.82 m @ 2.37 gpt Au, 22 gpt Ag; 7.5 m @ 6.74 gpt Au, 158 gpt Ag.
  • Megastar Development Corp. reported its exploration team is back at the Yautepec and Magdalena projects in Oaxaca. So far, they have found “highly prospective ferruginous (iron-rich) carbonate sinters and fault-controlled quartz veining and breccias in discontinuous erosional windows under post-mineral volcanic rocks over areas of several hundreds of meters”. These findings correlate well with the envisaged uppermost levels of an epithermal system, the concept exploration model used at the site.
