  • In Sonora, representatives of the State Congress proposed to form citizen committees to supervise the application of the Mining Fund (Fondo Minero). The proposal aims to give transparency to the application of the funds, and also a mean to control the infrastructure projects generated in the municipalities that are to receive the participation generated by the mining activity (Note of editor.- This is a pressing problem in many other States, where the application of the funds of a mining royalty introduced by the current Federal government is nowhere to be seen).


  • SilverCrest Metals Corp. released phase II drill results for the Babicanora vein at its Las Chispas property in Sonora. The latest results increase by 400 m the high-grade footprint of the Babicanora vein, which is now 1 km in length.

  • On Mexican Silver Production, Zacatecas has 40.8% participation, Durango 14.0% and Chihuahua 13.9%. Located in Zacatecas the Saucito mine is the largest primary silver producer in the world, generating 13% of the Mexican production. Silver production in Zacatecas decreased 11.5% in 2016, due mainly to lower grades at Peñasquito. In Durango, production decreased 23.7% by work interruptions at San Dimas and lesser output from Guanaceví. Construction of the La Preciosa (Durango), Pitarrilla (Durango), El Gallo II (Sinaloa), Cordero (Chihuahua) and Cerro del Gallo (Guanajuato) projects still await better market conditions to go ahead.

Production at Bolivar is expected to reach 3,000 tonnes per day (tpd) in Q1 2018 through the commissioning of 13 new pieces of equipment. At Cusi, the focus in on completing access, development and production of the Santa Rosa de Lima zone, with wider structures and grades than the narrow veins being mined now. Currently selected higher grade material from the old mine and development ore from Santa Rosa de Lima is being sent to the mill. Tonnage from the Santa Rosa de Lima structure is to be gradually increased until the mill operates at its 650 tpd capacity. A geological reinterpretation led to the discovery of the Santa Rosa de Lima zone, which averages 3.8m @ 372 g/t AgEq after two drill campaigns totaling 29,500 m.

• Maiden drilling program starts with 5 holes planned for 450m
• High priority drill targets include old mine workings and outcrop containing
high grade gold and cobalt mineralisation
Azure Minerals Limited (ASX: AZS) (“Azure” or “the Company”) is pleased to advise that diamond drilling of the first hole of a five-hole program has started on its 100%-owned Sara Alicia goldcobalt project, located in the northern Mexican state of Sonora (see Figure 1).
High grade gold and cobalt mineralisation was historically exploited by small-scale underground mining in the 1930s. Azure’s first-pass sampling of surface and underground exposures confirmed the presence of this mineralised zone, returning high grades of gold and cobalt up to maximum values of 39g/t gold and 7% cobalt (see Photo 1 and refer ASX announcement of 23 August).
A reconnaissance drill program has been designed to test this zone with an initial five holes totalling approximately 450m of diamond core planned (see Figure 2 for hole locations). A followup drill program may be undertaken, depending upon initial results.



All approvals granted for diamond drilling at Oposura and Sara Alicia
• Drilling expected to start on both projects within a week
• Two drill rigs at Oposura will enable resource estimation in early 2018
• Sara Alicia drilling to test high-grade gold-cobalt mineralisation
Azure Minerals Limited (ASX: AZS) (Azure or the Company) is pleased to advise that it is about to start drilling campaigns on both its new flagship Oposura zinc-lead-silver and the highlyprospective Sara Alicia gold-cobalt projects in the northern Mexican state of Sonora. The projects, both recently added to Azure’s Mexican portfolio, have received all required approvals from the environmental authorities and drilling is expected to start within a week.
