Climate Goals & Targets

Environmental Challenges

  • Lower silver prices resulted in the mine being put on care and maintenance in December 2013.
  • The mill failed to reach design production rates and projected silver recovery in 2012-2013.
  • Unreliable resource model for estimating mineralization extent, complexity, and location.
  • Mill assembled partly from used equipment unsuitable for design parameters.
Mitigation Strategies
  • New metallurgical test work and information on Shafter deposit, Presidio Mine operation, and recent Aurcana operation used to create a new mine model and refine the mill feed processing flowsheet.
  • Proposed activities to advance the Shafter project include cavity survey of Presidio workings, plan to improve definition of remaining Presidio mineralization, mapping Presidio workings, drilling to test zones, re-examining historic drill-hole data, updating the database, re-examining historic information, developing an accurate survey of land holdings, metallurgical testing, equipment inspection, thickener evaluation, and completing a pre-feasibility or feasibility study.

Climate Goals & Targets

Long-term Goals:
  • Not disclosed
Medium-term Goals:
  • Drill 16 holes to test the zone east of mine-grid 53,750.
  • Update the database with historic channel-sample information and re-sample some locations to confirm historic results.
Short-term Goals:
  • Rehabilitate existing workings and complete a cavity survey of the Presidio workings.
  • Develop a plan to improve the definition of the remaining Presidio mineralization.
  • Complete geotechnical investigations to establish design stope dimensions and a ground control management plan.
  • Complete hydrogeological investigations to determine expected water inflow by mine area.

Environmental Challenges

  • Lower silver prices resulted in the mine being put on care and maintenance in December 2013.
  • Design silver production rates were not met during 2012-2013 operations.
  • Unreliable resource model for estimating mineralization extent, complexity, and location.
  • Mill assembled partly from used equipment not fully suitable for design parameters.
Mitigation Strategies
  • Updated mine plan incorporating updated costs.
  • Recommended work program to upgrade inferred resources, including rehabilitation of workings, cavity surveys, geotechnical and hydrogeological investigations, drilling, and data updates.
  • Metallurgical testwork to optimize and confirm whole-ore leach recoveries.
