The payment from an effective tax rate to the mining sector of 45%is one more sample strict adherence to legality and government mechanisms that promote the socio-economic development of the country (San Jose mine, Oaxaca).
ON EXPLORATION
- One World Lithium Inc., announced that a drill crew will be mobilizing to its Salar del Diablo project in Baja California, to drill a third diamond drill hole. DDH-3 will be located approximately 50Km to the south of DDH-2.
- Colibri Resource Corporation, informed that it will commence a 3D IP survey at its Evelyn project in Sonora. The 3D IP survey will be focused on the Sahuaro and Cerro Rojo targets and will cover an area of approximately 6 square km. The Company is planning a drill program to test currently defined mineralized trends and structures, to evaluate the emerging geological and structural model for the property, and to test results of the IP survey.

Heliostar identified a silicified structure with pyrite and returned 1m channel sample grading 390 g/t Ag, and remains open to expand. Additionally, eleven channel and rock samples returned values >1 g/t Ag in a coherent anomaly that cover an area of 500m by 600m, being this area the extension of the Dos Amigos vein into the eastern block. This mineralization indicates a robust silver endowment and shows the potential for high grades in the eastern block of the El Picacho district.

The IP survey outlined a strong IP high chargeability anomaly of 1,400m north-south and 800m east-west at the south portion of the Alaska vein, at depths of 250 to 300 metres below surface, progressively increasing in width and intensity toward the south.

- Zacatecas Silver Corp., completed geological and structural mapping at its El Cristo project located immediately to the northwest of the Veta Grande deposit. The Veta Grande vein has reported historical production of over 200 M Oz Ag in the region.

Zacatecas Silver has commenced an extensive soil sampling program to assist with location of veins beneath cover of thin soils. “The cumulative strike length of all veins at El Cristo is at least 12 km long. El Cristo an extremely prospective system with numerous high value targets at vein intersections, splays and flexures. Veins display multiphase and brecciated textures, indicative of multiple mineralizing events. Zacatecas Silver is planning an aggressive rock-chip and channel sampling program to better define the silver-base metal grade distribution of the outcropping veins, to ensure that the highest value targets are drill tested”.
- Advance Gold Corp., started a drilling program at its Saldivar lithium salar project in San Luis Potosi to test near surface lithium grade distribution of the salar for bulk sampling preparation.
