ON MEXICO ISSUES, China is already the third biggest foreign player in Mexico. ON EXPLORATION, a PFS was completed on a property in Durango, while in Chihuahua a drilling campaign continues and another one is on the planning stage. In Sonora results from a drilling campaign on a gold property were released, as were surface rock chip results from one Li property. In Hidalgo a property was staked, showing interesting initial rock chip sample results, whereas in San Luis Potosi and Zacatecas assay results were released for a Li property.  ON MINING, construction of a heap leach processing plant has begun in a project in Sonora, while in Sinaloa the high grade output was increased in one property, and development work continues in another one. In Queretaro a flotation mill continues with production tests. ON FINANCING, A C$10 M bought deal financing was completed by a company. ON RESOURCES, a technical report with a maiden resource was filed at SEDAR, and a PFS was completed on another, both from properties in Durango. ON DEALS AND CORPORATE ISSUES, the saga for the control of a property in Sinaloa continues, a property was optioned and one more sold, both in Sonora. A company is applying to be listed in USA and a second payment has been made on the option to earn interest on a tailings property in Durango.

  • Telson Resources Inc. announced the completion of a pre-feasibility study (PFS) on its Tahuehueto property in Durango. The report states a proven mineral reserve of 3.3 M tonnes @ 3.4 g/t Au, 41 g/t Ag, 0.31% Cu, 1.1% Pb and 2.0% Zn, to be mined mainly by underground cut and fill method at a 790 tpd rate, with a mine life of 21 years.
